Char Input and kbhit() equivalent function injava

May be its very simple question.
But can anyone please suggest me how to get char as input from keyboard and store it into char primitive type.
and also suggest equivalent kbhit() function in java.
please be more elabotative so that noviece can easily get.

Please tell how to do it.This is where it gets complicated. You will have to create a JNI wrapper for kbhit() .
I would suggest you find a different way of getting input to your program.

Type input and command key functions don't work

I have regularly been experiencing problems with the type cursor not moving and not inputing type while using the keyboard. Also while this occurs command key shortcuts and the force quit dialog box won't appear on the screen after pressing the command, option and escape keys. The only temporary solution I have at the moment is choosing restart from the Apple menu.
Any suggestions or help with this would be appreciated!

You might try repair and maintenance, which Dr. Smoke goes into detail here:
http://www.thexlab.com/faqs/faqs.html
I've had keyboard problems that I fixed by running repairs.
You could also have a bad keyboard. If it's a non-Apple keyboard make sure you have the most up to date software for it. If you happen to have a spare keyboard plug that in and see if it happens with a different one.

Synchronize input and output tasks to start at the same sample point [C++ NI_DAQmx Base]

I'm trying to initiate the analog input and output streams to start reliably at the same sample. I've tried triggering the output from the start of the input using the following code [NI-DAQmx Base 2.1 under Mac OS X with an M-Series multifunction board].

Hi Michael,
First of all, thanks very much for taking the time to investigate this problem! Much appreciated.
You asked for "an actual error code you got and any description that is given". The full output from the program that I posted earlier in this thread is appended to the end of this message. In summary, following the call to...
DAQmxErrorCheck ( DAQmxBaseCfgDigEdgeStartTrig( outputTaskHandle, outputTrigger, DAQmx_Val_Rising ) );
... with ...
char outputTrigger[] = "Dev1/ai/StartTrigger";
...the error message is ...
DAQmxBase Error: Specified route cannot be satisfied, because the hardware does not support it.
You asked "specifically which M series device you are using"? It is the PCIe 6251 (with BNC 2111 connector block). I'm testing and developing on an Intel Mac Pro (dual boot OS X and Windows XP).
You asked for "the location you pulled the code from". Here it is...
http://zone.ni.com/devzone/cda/epd/p/id/879
...specifically from the file "Multi-Function-Synch AI-AO_Fn.c".
I adapted the NI-DAQmx calls to their NI-DAQmx Base equivalents.
Finally, you asked "Is the trigger necessary, or do you just need to know that the measurements are running on the same clock?". I believe that some kind of sychronized trigger is necessary in my situation (correct me if I'm wrong). Timing is crucial. Say I initiate an analog output stream that delivers a voltage command step 5 ms from the onset. I need to record the response (analog input stream) so that its onset is accurately aligned (synchronized) at 5 ms. A typical recording situation would stimulate and record a short data 'sweep', then wait for the (biological) system to recover, then stimulate and record another short sweep, and repeat. I need all the recorded sweeps to align accurately so that they can be averaged and analyzed conveniently.
I definitely do not want my customers to rely on an expensive external TTL pulse generator to initiate and synchronize each 'sweep'. That would effectively eliminate the cost advantage of an NI board, as well as adding unnecessary complexity in setup and use. It would be a show-stopper for me.
It seems perverse, but would it be possible to use a digital output channel connected directly to a digital input chanel to trigger the input and output streams?
Regards,
John.

How can I pass Recordsets as input parameter to a Function ?

Hi Gurus,
I want to create a function that receive recordsets as input parameter also returns recordsets as output.
I have a requirement to do stock taking for all order items of one Order number in one single query execution (to avoid row by row basis).
From the post in the forum I know that a function can return recordsets / query result using REF CURSOR or pipelined table function.
My question is : how to pass the recordsets as input parameter to that function ?
(because I could have 75 rows item in one order number)
Below is the DDL and the query :
create table stocks (Product char(4), Warehouse char(5), expireddate date, qty_available number)
insert into stocks values('P001', 'WH001', '01-dec-2006', 30)
insert into stocks values('P001', 'WH002', '01-dec-2006', 50)
insert into stocks values('P001', 'WH002', '01-jan-2007', 50 )
insert into stocks values('P001', 'WH001', '01-Mar-2007', 150)
insert into stocks values('P002', 'WH003', '01-dec-2006', 25)
insert into stocks values('P002', 'WH003', '15-Jan-2007', 50)
insert into stocks values('P002', 'WH003', '01-Mar-2007', 75)
insert into stocks values('P003', 'WH001', '01-dec-2006', 30)
insert into stocks values('P003', 'WH002', '15-Jan-2007', 40)
insert into stocks values('P003', 'WH003', '01-Mar-2007', 50)
CREATE TABLE Order_Detail (PRODUCT_ORD CHAR(4), QTY_ORD number, Priority_WH CHAR(5) )
INSERT INTO Order_Detail VALUES ('P001', 75, 'WH003') // previously 'WH002'
INSERT INTO Order_Detail VALUES ('P002', 45, 'WH002')
INSERT INTO Order_Detail VALUES ('P003', 55, NULL)
The query for stock taking :
select product,warehouse,expireddate, least(qty_available-(sm - qty_ord),qty_available) qty
from ( select product,warehouse,expireddate,qty_available,qty_ord, sum(qty_available) over(partition by product order by s.product,expireddate,decode(warehouse,priority_wh,0,1),warehouse ) sm
from stocks s,order_detail o
where s.product = o.product_ord order by s.product,expireddate,decode(warehouse,priority_wh,0,1) )
where (sm - qty_ord) < qty_available

Hi,
This my requirement :
I have (simplified)Order_Detail as below :
CREATE TABLE Order_Detail (PRODUCT_ORD CHAR(4), QTY_ORD number, Priority_WH CHAR(5) )
INSERT INTO Order_Detail VALUES ('P001', 75, 'WH003') // previously 'WH002'
INSERT INTO Order_Detail VALUES ('P002', 45, 'WH002')
INSERT INTO Order_Detail VALUES ('P003', 55, NULL)
Then I want to do stock taking from my STOCK table (described on my first post on this thread)
create table stocks (Product char(4), Warehouse char(5), expireddate date, qty_available number)
The rule is : The stok taking is on First In First Out basis, on expireddate.
And I want to do it in single query.
I want to make this a Function / Stored Procedure so that other transaction can also make use of this query.
That is why I need to pass the 3 rows oy mr Order_Detail above, do the query, and return the result.
Then INSERT the result into ORDER_DETAIL_PER_EXPIRED_DATE table.
I hope this clear my requirement, is this possible ?
Thank you,
xtanto

How can I use a different driver for audio input and output?

I did a search of course, and came up with something about an aggregate. I have no idea what this is, how to do it, or if it would even work for me.
What I am trying to do is:
1) Record into Logic Express using my Tascam US-122.
2) Have playback come out of my computer sound system, not the Tascam.
If I go over to the Audio setup window, I can only record when the driver is set to Tascam US-122. Likewise, I can only listen to sound when my Built-In Audio is selected. It gets rather annoying going between the two.
So, would this aggregate thing solve my problem? If so, how do I do it? Thanks for any help!
-allen

Yes it should do what you want.
Go to "Audio Midi Setup", and go to the Audio menu and click "Open Aggregate Device Editor". The interface is pretty simple but if you do get stuck, just use the help function in Audio Midi Setup, as it has a step by step guide.
Then when you return to logic, go to the Preferences>Audio>Drivers section and select Aggregate Device as the new driver rather than either the built in sound or the tascam. Then the inputs and outputs will apply to BOTH devices.

SSIS: How to use one Variable as Input and Output Parameter in an Execute SQL Task

Hello,
i need your help,I'm working on this issue since yesterday and have no idea how to deal with it.
As I already said in the tilte i want to start a stored procedure via a Execute SQL Task which has around 15 prameters. 10 of these should be used as input AND output value.
As an example:
i have three Variable:
var1    int        2
var2    int     100
var3    int     200
the stroed procedure:
   sp_test
     @var1 int
      @var2 int output
      @var3 int output
   AS
   BEGIN
        SET @var2 = @var2 * @var1
        SET @var3 = @var3 + @var1
   END
So in the Execute SQL Task i call the Stored Procedure as follwos:
    Exec sp_test  @var1 = ?, @var2 = ? output, @var3 = ? output
(I use an OLE DB Connection)
The parameter mapping is as follows:
User::Var1        input                   numeric              0                 -1
User::Var2        input/output         numeric              1                 -1
User::Var3        input/output         numeric              2                 -1
Now my problem. If i set  Var2 and Var3 as Input parameter the values are still the same after running the package. If i set them to a output value the are both Null because the procedure doesnt get any values.
I already tried to list them a second time - like
    User::Var2        input                  numeric              1                 -1
    User::Var2        output                 numeric              1                 -1
or i use a new variable
    User::Var2                  input                  numeric              1                 -1
    User::Var2Return        output                 numeric              1                 -1
but i alwas get the error
"Multiple-step OLE DB operation generated errors. Check each OLE DB status value, if available. No work was done."
Has anybody an idea how I can solve this problem?
Thanks a lot.
Kind Regards,
Alice

Hi Alain,
thx for your answer.
I have around 15 procedures called one after the other to calculated and modify my values. Each procedure is responsible for an other but overlapping set of variables. So i thought it would be a good idea to call them one after the other with the needed variables via a execute sql task.
So if i use a result set, how i get my stored procedure to return 10 values? I would have to use a Function instead of a procedure, wouldn't i?
As if i have 15 procedures this would be a lot of work.
But thanks a lot for the idea. I think an other idea would be to create one function which calls all stored procedures and returns all the calculated values as a result set, wouldn't it?.
Kind Regards.
Alice

Audio Line-in input and BT Headset output not working

Hi,
I'm trying to run the Line-in into my MBPro and route the output to my Logitech H800 BT Headphones at the same time (a pass through), but can't get it to work.
I have tried to run the line-in to the Internal Speakers and can not get this to work either.
Steps to taken:
1. Go to the Sound window by selecting the Sound icon from System Preferences.
Next, I route the Line-in by:
2. Selecting the Input button from Sound Effects, Output, Input buttons.
3. Select "Line In" from the Select a device for sound input list.
4. Select "Sound Input" from the Use audio port for drop down list
5. you should see activity on the Input Level.
6. Next, select the Ouput button from Sound Effects, Output, Input buttons.
7. Select "H800 Logitech Headset Stereo (or Internal Speakers) from the Select a device for sound output list.
8. Verify that "Sound Input" from the Use audio port for drop down list is still selected.
9. Also, verify that the Mute checkbox is not selected in either the Input or Output window.
10. NO SOUND :-(
11. If I pull up a radio station in a webbrowser, I can listen to it without issue. So, I think audio out is set correctly.
12. If I install Audacity: 1) It shows the audio input and output to be set as above (Built-in Input/H800 Headset). 2) If I record and then playback, it records the audio going in the Line-In and plays back accross the H800. 3) Also looked for a Monitor function in Audacity but could find one to test simulataneous I/O.
Any idaes welcome ?

ahh sry, thats how the line in works on my Mac Pro, I guess the Macbook is different. This is a program I use in conjunction with another called 'soundflower' to route my audio to all the places it needs to go:
http://www.macupdate.com/app/mac/11333/linein
If you need to run multiple instances, you can open up terminal and type
open -n /Applications/[PUT PROGRAM NAME HERE].app/
It will open up another instance every time you run that script.

How to use a bluetooth cellphone for audio input and output

Hello, I was wondering how to set-up my Mac Book so that I can use my bluetooth cellphone for audio in and audio out. Ideally, I would like to use my handset for talking on iChat and Skype. Has anyone had any luck doing this? When I bond my cellphone these optiosn do not appear. I know that this is easy to do on a Windows machine but I am not sure about how to do it on my Mac Book.
Thanks!

Is it possible to create a Webservice in BI which takes XML as an input and gives PDF as output with an additional requirement that Siebel expecting the XSD from BI to send data in the BI requested format

Is it possible to create a Webservice in BI which takes XML as an input and gives PDF as output with an additional requirement that Siebel expecting the XSD from BI to send data in the BI requested format. Siebel wants to send the data as xml to BI but not sure of the BI capabilities on giving WSDL embedded with XSD (input is a hierarchical)

Hi All,
I am able to fulfil above requirement. Now I am stuck at below point. Need your help!
Is there any way to UPDATE the XML file attached to a Data Definition (XML Publisher > Data Definition) using a standard package or procedure call or may be an API from backend? I am creating an XML dynamically and I want to attach it to its Data Definition programmatically using SQL.
Please let me know if there is any oracle functionality to do this.
If not, please let me know the standard directories on application/database server where the XML files attached to Data Definitions are stored.
For eg, /$APPL_TOP/ar/1.0/sql or something.

Simultaneously read more than one input and generate output

Is it possible To simultaneously read more than one input and generate outputs depending on these inputs? If this isn't possible what is the best way to go about making some sort of timed loop that will read an input, read the next input, decide whether or not to output and so on. Hope someone can help. Thanks.Message Edited by Esmith13 on 05-25-2005 01:36 PM

Hi,
You should look at the synchronized examples for analog input and output that can be found in the example finder under:
Help>>Find Examples>>Hardware Input and Output>>DAQmx>>Synchronization>>Multi-Function
These will get you started to being able to handle multiple tasks at the same time.
I hope this helps. Have a Great Day!

FINALLY INPUTTING and OUTPUTTING Annotations!

Ok, before everyone thinks that this is a very bad solution, I have to tell that I`m no programmer and my knowledge of PostgreSQL, Ruby or any other language is very poor.
With useful help from Jamie Hodge, fbm and Nicholas Stokes (mainly)
I could manage to write a command for inputting and outputting from Final Cut Server Annotations.
So lets go to the fun part:
INPUTTING:
1- Create a Response called "Annotations IN" (or whatever you want):
a - Reponse Action: "Run an external script or command"
b - Run Script > *Commnad Path: /Library/Application Support/Final Cut Server/Final Cut Server.bundle/Contents/Resources/sbin/fcsvr_run
Command Parameters: psql px pxdb -c "COPY pxtcmdvalue FROM '/FCSRV/annotation-in.txt' USING DELIMITERS '|';"
2 - Create a poll Watcher with name: "Watch for Annotations IN"
a - Enable: true
b - Monitor Address: Chooses a Device (create a new one or use a tmp one) and path to where you`ll going to put a txt file with the annotations.
c - Response List: Choose the Response you created "Annotations IN" in my case.
d - Event Type Filter: Created, Modified
e - Poll Watcher > Listing Frequency: 2 (or any number of seconds you feel like it).
Listing multiple: 2
Wildcard include Filter: *.txt (or any custom extensions you want)
3 - Create a txt file and use this as a template:
{ASSET_ENTITYID}|1527|{TCIN}/(30000,1001)|{TCOUT}/(30000,1001)|{Annotation}|{USE RID}|{DATE}
Where:
{ASSET_ENTITYID} = Is the entityid of your asset. You can find what number it is by issuing:
/Library/Application\ Support/Final\ Cut\ Server/Final\ Cut\ Server.bundle/Contents/Resources/sbin/fcsvr_run psql px pxdb -c "SELECT pxmdvalue.entityid, pxmdvalue.value AS asset_name FROM pxmdvalue INNER JOIN pxentity ON pxentity.entityid = pxmdvalue.entityid WHERE pxmdvalue.fieldid='1543' AND pxentity.address LIKE '/asset/%';"
This will output ALL your assets, so if you know the name or want to parse the name you can use:
/Library/Application\ Support/Final\ Cut\ Server/Final\ Cut\ Server.bundle/Contents/Resources/sbin/fcsvr_run psql px pxdb -c "SELECT pxmdvalue.entityid, pxmdvalue.value AS asset_name FROM pxmdvalue INNER JOIN pxentity ON pxentity.entityid = pxmdvalue.entityid WHERE pxmdvalue.fieldid='1543' AND pxmdvalue.value='ASSETNAME' AND pxentity.address LIKE '/asset/%';"
Where in ASSETNAME you`ll have to put your Asset Name without extension.
{TCIN} and {TCOUT} is, of course, the TC`s points. In the form of: HH:MM:SS;FF
{Annotation} is the commentary.
{USERID} (in my case was 1)
{DATE}: This one is tricky. My example is 2009-03-15 19:31:15.839795-03
So is in the form YYYY-MM-DD HH:MM:SS.????? I really don`t know the rest. Could be milliseconds?
Of course one can write a script to translate everything from a txt file like:
ASSETNAME | TCIN | TCOUT | ANNOTATIONS | USER
But as I`ve said I`m no programmer
Ok.. now the time for the OUTPUT:
The command-line is:
/Library/Application\ Support/Final\ Cut\ Server/Final\ Cut\ Server.bundle/Contents/Resources/sbin/fcsvr_run psql px pxdb -c "SELECT pxmdvalue.value AS Asset_NAME, pxtcmdvalue.value, pxtcmdvalue.begintc, pxtcmdvalue.endtc FROM pxmdvalue INNER JOIN pxtcmdvalue ON pxmdvalue.entityid = pxtcmdvalue.entityid WHERE pxmdvalue.value='ASSETNAME';"
Where ASSETNAME is the Asset name without the extension.
Or issuing the following to OUTPUT ANNOTATIONS from ALL assets:
/Library/Application\ Support/Final\ Cut\ Server/Final\ Cut\ Server.bundle/Contents/Resources/sbin/fcsvr_run psql px pxdb -c "select * from pxtcmdvalue;"
Adding "> /PATHTO_WHERE_IN_WANT/ANNOTATIONSOUTPUT.TXT" at the end will put all output into a txt file.
It`s possible (in theory) to:
1- Create a boolean md field in FCSRV called "EXPORT Annotations" (don`t choose lookup)
2- add or create a md group called "Export Annotations" and add the above md field to it (don`t choose lookup)
3- Add "Export Annotations" md field to Asset Filter md group
4- Make a Response for Running external command. Command path: /Library/Application Support/Final Cut Server/Final Cut Server.bundle/Contents/Resources/sbin/fcsvr_run
Command Parameters: psql px pxdb -c 'SELECT pxmdvalue.value AS Asset_NAME, pxtcmdvalue.value, pxtcmdvalue.begintc, pxtcmdvalue.endtc FROM pxmdvalue INNER JOIN pxtcmdvalue ON pxmdvalue.entityid = pxtcmdvalue.entityid WHERE pxmdvalue.value=[FileName];' > ~/Desktop/ann-out.txt
(I`m having problem with this, it doesn`t work).
5- Make a Subscription that if Export Annotations modified = true, trigger if changed and trigger the Response above.
6- Add exporting annotations md group to Media md set.
In theory it`s possible to modify the FinalCutServerIntegrationSample get and input annotations instead of adding another "comment" field to md group list.
Few!
Ok so please help beautify this out!
This will be very useful for a lot of people.... We know that it`s only a matter of time to FCSVR have this function built-in... but this "time" could be years.
So let`s start ourselves!
Thank you very much!!
Regards!

I need to accomplish this without the use of a community-created library.That's a bizarre requriement. Why?

Okay, [here you go|http://lmgtfy.com/?q=communication+between+StarOffice+Spreadsheets+and+Java].
If you don't have any knowledge or experience, on the matter, please refrain from directing me to a google search. I assure you, I have already performed such a task.How would I know that.
But okay, let's say I know that. Let's say you bothered to point out that you've already done that. Further, let's say I do have knowledge of the subject at hand. Maybe I'm an expert. Maybe I wrote Star Office and an open source library (which wheel for some reason you must reinvent). You are assuming that I also have psychic powers, so that I can read your mind and know exactly what you've read so far and exactly what parts of your very broad and vague question said reading did not answer.
In short, you have received answers commensurate with your questions.

XSLT Generation from input and output XML

Is it possible to generate an XSL mapping file in Java if we have input and output XML.
If yes, then how to achieve this when user defined functions are used during mapping?

How to temporally match/save Input and Output Channels's data?

Hello, I have a voltage-input, voltage-output SISO system, and need to indentify its dynamic response (or transfer function) as a reference to a PID control. Without using the system identification toolbox, my goal is to generate/provide a sine sweep input (ranging 1Hz-5kHz for 10sec) to the system and to save the corresponding output response signal as well as the sweep input signal simultaneously.
I got a sample program online and am trying to modify it as attached, but I really need your advices/comments concerning several problems I am facing with:
1) With the below setting, the number of the acquired Input channel samples obtained is 5461, which is smaller than expected (i.e., 10000). What would I be missing in setting parameters?
- H/W: NI-USB-6341 DAQ
- AO: continuous samples with the waveform timing (1k sampling, 10000 samples => 10 sec, slower sampling just for testing purpose)
- AI: continuous samples, samples to read: 30k, rate: 1k
2) I am using flat sequence structure as a way to making the start point of saving AI and AO data same, but wonders if this is a right method or if there is other better approaches. (I had an idea of using an internal clock with "1-sample mode" for sync, but this may not work at the high speed sine sweep like 5kHz, right?)
3) I just want to provide the sine sweep just once to the system and do not require the "reset" functionality implemented in the original sample program. I failed to remove this "reset" part as I did not fully understand the sample code. If I run the attahed, the generated AO signal is periodically provided to the system. Please give me any advice to modify the program as I want.
Thanks for your help and valualble time.

Hi J. Kim,
To begin, you say you want to synchronize your analog input and output so that they start at the exact same time, yes? To achieve tight synchronization, you need to use DAQmx VIs instead of the DAQ Assistant. There's a good overview of DAQmx VIs here. There's also a document that deals specifically with synchronization in DAQmx here. Additionally, if you go to Help>>Find Examples in the LabVIEW example finder, you can see many other examples of acquiring data using DAQmx.
As for your configuration, you have your analog input DAQ assistant wired far before your analog output DAQ assistant in your sequence strucutre, so the dataflow of the program will cause the analog input DAQ Assistant to execute before the output. They cannot be in different sequences if they are executing simoultaneously, and I would not use flat sequences here except to start the two tasks in DAQmx. Where did you find this example?
Best,

Multiple inputs and outputs using DAQmx VIs

Hello,
I am fairly new with the LabView programming language. I have a few training books that I have been reading, and I have been following online tutorials and reading the forums. However, I have come to a problem where I don’t see a clear solution. I am using LabView 2009 (9.0f3) and DAQmx VIs.
I am using a NI 9172 chassis PLC, with two 9201 AI cards, 9217 AI RTD card, 9472 DO card, 9263 AO card, and two 9237 AI Bridge cards.
I am reading eight analog inputs with the 9201 cards, two analog RTD inputs with the 9217 card, three digital outputs with the 9472 card, three analog outputs with the 9263, and eight analog inputs with the 9237 cards.
I wrote a simple program to test one digital output task, two of the analog output tasks, and a single analog input task. I put all of them in the same while loop, and it worked perfectly. However, when I add analog input tasks to the same loop, I get an error 200022. So I tested each sensor individually by changing the channel before each run. I searched error 200022 and found that this is because I cannot start another analog input task until the previous one ends. With this said, I don’t know how to acquire an analog voltage in the same task as an analog RTD voltage. Both inputs take different constants in the start task DAQmx icon.
Attached is my test program. It is titled “Test All”. This is the program I used to test the various sensors. I tested the input sensors one at a time, and it worked fine. A few tasks are written just to test functionality, and will be added to later. The data is only displayed on the screen. I will add triggers and data write to disk functions later. This program works now, but if I add more analog inputs, it will generate the 200022 error.
Can someone show me how to correctly write the code for multiple inputs and outputs using DAQmx? All training materials and tutorials I can find all show a single input or single output, not multiples of each. Thanks for looking.

Hi RandyC,
The Knowledge Base article Using Different Types of DAQmx Global Channels in the Same Task goes into a little more depth of what Bryan is talking about, and it also includes some example code to help show what to do.
Hope that helps,

How to get signal from analog input and send it to analog output (real-time)

Hi everyone,
I am doing simple task in Visual C++ and I am using PCI-6221(37 pin).
Basically, I want to send same signal from 'analog input' to 'analog output'
at the same time (almost), to make it real-time application.
Can someone please provide me sample program.
I would appreciate if you could provide me with the good tutorial which explains
step by step everything about programing NI-DAQmx for C/C++.
Best Regards,
Khassan
Solved!
Go to Solution.

This is my code in C++, you can optimize it if it looks too messy. This code reads signal from analog input and outputs it through analog output.
To make this code work additional include directories and library directories must be added from NI.
I hope it helps someone.
