Poly input
Is there a way to create a SubVI with a real poly input? I mean an
input wire that takes anything, like the one in Flatten to String, without losing information what
"anything" is - it may be a custom cluster that sub knows nothing about.
What I would want is to serialize this cluster for data transmission
in little-endian order using Flatten to string, but I want to flatten
the raw data, it cannot be encapsulated into a variant (I suppose that
"Variant" carries some additional meta-data - I still have to check
this).
I hope I have correctly describe what I want to do - I have a feeling
this sort of thing is very hard in LabVIEW.
Thanks in advance, Mike

Yes, you can make polymorphic VIs.
Do you have a specific example you are looking to impliment?
Thank you. I am aware of the polymorphic VIs, but their limitation is, that the input type has to be known up front. I am looking for a way to get something similar to the real "poly input" that is only limited to LabView native VIs. I want to implement a function that can serialize any input in "little-endian" form an then send it over the wire. My goal is to have serialization "hidden" from the user. One idea is to have the Variant input, but the data sent would have to be "raw" (without the encapsulating variant). But the challange is, how to "unvariant" without knowing what is inside.
On Lavag someone suggested the VariantType library (I've somewhat forgotten about that), but it suggested that it is slow. I think it might work for me, but another challange after that is, how to put the "raw" data I receive into a variant without knowing what is inside. The data will be serialized in little-endian format, so "Variant to Data" would not strip it in the correct byte order.
I have an idea, but I would have to test it first...

Score staff problems with keyboard input
Hi. I am trying to input midi keyboard notes, in real time, into Logic Pro. This works fine. However, I'd also like to create a reasonable, normal score from those notes. The problem is that the notes are divided between the bass and treble clefs. This isn't at all readable when, for example, a chord played with the right hand is say, an A minor chord with the C note being middle C. The 3 notes should all appear in the treble clef.
When I try to move the note from the bass clef to the treble clef, I get messages that I need poly voicing and when I follow the help files to add another voice, I get a new clef. The only way I've been able to figure out how to do this is to record the left hand and right hand parts in different tracks, separately, which is quite cumbersome.
This ought to be easy! What am I missing?i have to say i have created extremely complex and sophisticated concert music scores using logic. it can be done despite a myriad of problems and bugs. it's great advantage is flexibility and speed, there is nothing wrong with what it should be able to do, it just trips you up at the very last hurdle - hugely frustrating because it gets you there well ahead of the game.
i can tell you through the grapevine that improvements and upgrading are on the way for the score editor. it is very useful to have the likes of all the people on this thread posting because score users are under represented on the forum. logic developers don't realize how many of its users depend on its score features, because most of us don't post.
now some important tips:
- you can set a default score style in the arrange window in the paramters box when you click on a midi instrument track. that means whenever you create a midi region it will be in that score style.
- being able to select score styles for different regions is a good thing!!!! this way you can speed up your work flow incredibly - way way faster than sibelius or finale.
Rests have to be written instead of automatically appearing.
rubbish! you can set the rests to appear automatically. use differing score styles.
I wanted to say that I am hugely disappointed with apple's neglect of the score windo
now there i am with you brother.
if you want to see what can be achieved using score in logic, even in the state it's in you can have a look at a sample of my violin concerto i have at my website:

One MIDI input, one set of modulation parameters for the EXS24
This might be somewhat of a neophyte question, but here goes:
I'm interested in being able to set a specific set of modulation parameters for each note in series of notes inputted into the EXS24. I'd like to be able to bypass any sort of complex routing techniques with the modulation matrix or automating the parameters in the arrangement window. For instance if I input 2 C1 notes, one right after the other, of the same length, I'd to be able to set the velocity, filter values, ASDR values, etc. of the first completely independently from the second. The main reason I ask this is that for instruments such as a guitar (which has multiple strings), one note might be able to be played at high velocity, high release, low attack, for instance, while another one might be played exactly after that (on a separate string maybe) with low velocity, high release, high attack, etc., etc. In order to achieve this more realistic sound, would I have to work with multiple instances of the EXS24 (and then maybe just group them all together?), or is this sort of micro-manipulation of all the modulation parameters for each individual midi note input somehow possible with just one instance of EXS24?
Hope this makes sense!Do you have a controller with polyphonic after touch? you can already have different velocities for note attacks and filters with a standard velocity sensing keyboard. If your board sends release velocity you can also have a different release for each note. With poly after touch you can have different vibrato depth for each note. If you want differing mod speeds for different notes I'd have to give it more thought...

CRC code?: x^8+x^7+x^2+1 poly, FDBK=0xA1, init val=0xFF
I'd like to generate a CRC CCITT code. I found some that are 8 bit, but they are few compared to 16 and 32 bit.
Looking at the vi's, I don't see how the generating poly is being used, nor how the feedback value is being used?
There is not much to go on...? I have a set of values to use as a verification that the code is generating the right CRC:
U11=0x65, W1234=0xCF, W12=0x76, M01=0x43 etc. Input is a generally a letter followed by a pair or quad of numbers generally.
Anybody know what to make of this? I have some C code that apparently does the calculation, but I don't want to post it here.
Many Thanks!Smercurio,
They are things that I found on the NI discussion boards such as this:
http://forums.ni.com/ni/board/message?board.id=170&message.id=66012&view=by_date_ascending&page=1
There was a spiffy 16 bit CRC that was posted there by Waldemar, and I attach it. I don't know how to reduce it
to 8 bits, and wondered how to do that. It has lots of knobs and switches to adjust things, always desirable when reverse engineering something like this. I found it impressive. (There are other worthy candidates out there, too...) I don't think reducing the order of the polynomial is sufficient to take you to 8 bits, because of the XORing all the way through.
I do have a lookup table and I figured out how to use it. I have a snippet of C code that might generate the table. I am rusty on C,
but think I know what it is doing to generate the table. I may be able to generate the table in Labview, -without testing it in C first, -though I 'd prefer the satisfaction of knowing that the code I am working from, is right. It is amazing how different all the CRC vi's look compared to eachother.
The table is only 256 values, so I can type those into an array by hand and that will suffice, to get my application up and running.
I'd still like to know how to make a CRC generator myself, how to change the number of bits as well as the polynomial.
The feedback constant 0xA1 is used to generate the table itself, but not otherwise, so that clears that up.
Thank you for the DLL suggestion. I did not know about that and it may prove useful. I don't have a C compiler, but I can probably access one if I need to.
Thank you again. -sroman -
Error while running a query-Input for variable 'Posting Period is invalid
Hi All,
NOTE: This error is only cropping up when I input 12 in the posting period variable selection. If I put in any other value from 1-11 I am not getting any errors. Any ideas why this might be happening?
I am getting the following error when I try and run a query - "Input for variable 'Posting Period (Single entry, mandatory)' is invalid" - On further clicking on this error the message displayed is as follows -
Diagnosis
Variable Posting Period (Single Value Entry, Mandatory) is used as a lower limit (X) and an upper limit () in an interval selection. This limit has the value #.
System Response
Procedure
Enter a different value for variable Posting Period (Single Value Entry, Mandatory). If the value of the other limit is determined by another variable, you can change its value also.
Procedure for System AdministrationOK.
Well, if the variable is not used in any interval selection, then I would say "something happened to it".
I would make a copy of the query and run it to check if I get the same problem with period 12.
-> If not, something is wrong in the original query (you can proceed as below, if changes to original are permitted).
If so, then try removing the variable completely from the query and hardcode restriction to 12.
-> If problem still persists, I would have to do some thinking.
If problem is gone, then add the variable again. Check.
-> If problem is back, then the variable "is sick". Only quick thing to do, is to build an identical variable and use that one.
If problem also happens with the new variable, then it's time to share this experience with someone else and consider raising an OSS.
Good luck!

Hi,
After running some updates yesterday, the "show text input options" is no longer available in the options. Neither can I select suretype when writing a message. Would appreciate some help.
Thanks
Solved!
Go to Solution.Had to re-boot after removing an application and everything back to normal! What bugs me is that my service provider tech never brought up a re-boot but rather wanted me to delete all my data and start all over!

Open and close data input in DP.
Hi,
We have two periods in the future (actual and next) and we need open and close
actual year for input with macros.
We have built two macros to open and close actual year for input. The macro
to close the input is working OK (COL_INPUT( 0 )). the macro to open the input (COL_INPUT( 1 )) works OK too,
but the color doesn´t change, It goes on in grey color instead of white color.
We have used some operators (ROW_BG(), ROW_FG()...) to try to change the color but doesn´t change.
Did you Know how to bulid the macro to open actual year changing to white color?
Thanks in advance.
Raúl.do you mean it is grey but you can still enter data?
check what your "input from" date is on the planning book design(data view tab)
I have seen this happen too... But, since you are using the column input macro you can let your input from be right from the beginning and use the macro to make it open and closed at the relevant years(means you set the column_input (0) for history too
the KF that should not be edited is set in the setting "output only" -
[Interface] - Passing variety parameters/input to PL/SQL report
Hi,
I've the PL/SQL report which can allow passing in the parameter, i use '&'.
the report is given to the end user who do not have the IDE for PL/SQL. the machanism of the report is generated into the spool file and import into excel format.
now i am wondering how to create a tool using SQL or PL/SQL to allow the end user to choose the parameter(s) dynamically and passing into the PL/SQL to generate the report based on the input selected.
the parameters like below:
package code :
week no :
year :
department :
all the above parameters, the data would be selected from the existing lookup table. the user is allow to select more than 1 input for specified parameter for instance i want to spool report for week 1 until week 5.
pls advise any solution on this topic. thankshi scoot,
thank for reply.
yep, i'm using sql*plus and also sql navigator 4.0 .
the user don't have the software to interact. i'm thinking of build an simple interface using VB and passing in the parameter then initiate the sql*plus to run the program in background mode.
but if you have any other solution which not need to use other software to wirte such program , pls let me know immediately. thank -
Debugging is not working in R/3 from WebDynpro-ABAP developed webpage input
Dear Friends,
We are facing a serious problem for debugging. Expecting valuable input for the same.
Debugging is not working in R/3 from WebDynpro-ABAP developed webpage input in Production Server.
The debugging (for WebDynpro-ABAP application) is working in Dev. Server for
1st ] Within R/3
Ex. debug for bapi within R/3. i.e. value enter as input in R/3 only.
2nd ] From webpage to R/3
Ex. Some input given on the internet web page developed through WebDynpro and external breakpoint set in R/3 it works. It directs to R/3 code through debugging.
In Prod. Server the 1st case above is working but the 2nd case is not working.
In Prod. Server the WebDynpro developed applications are running successfully through internet explorer webpage inputs. So running the application is not a problem in prod. Server but debugging of the same is the problem.
The setting which are done in Prod. server are,
1] RZ10 in parameters are set for port and host name.
2.1] In SMICM check for ICM.

How to input data into an arraylist from a text file?
I am trying to take data from a text file and put that data into an arraylist. First here is the text file:
[item1, 10, 125.0, item2, 10, 12.0, item3, 20, 158.0]
3
4530.0
[item5, 65, 555.5, item4, 29, 689.0]
2
56088.5
[item7, 84, 34.5, item6, 103, 0.5, item8, 85, 1.36]
3
3065.1The text between the [ ] is the output from my arraylists. I have three arraylists. The first [ ] belongs to arraylist A, the second to arraylist B, and the third to arraylist C. The format of the arraylists is this:
<item name>,<# in stock>,<value of one item>
The first number below the arraylists in the text file represents the number of items in the list. The second number below the arraylists represents the total value of the items in the arraylists.

}Right now I am stuck on this and I cannot progress any further until I figure out how to input the data in the text file back into a arraylist.
Thanks in advance.Thanks but I figured it out. Heres a sample of the code i used to solve my problem:
try
//Warehouse A BufferedReader.
BufferedReader inA = new BufferedReader(new FileReader(inputFileWarehouseA));
//Warehouse B BufferedReader.
BufferedReader inB = new BufferedReader(new FileReader(inputFileWarehouseB));
//Warehouse C BufferedReader.
BufferedReader inC = new BufferedReader(new FileReader(inputFileWarehouseC));
//Warehouse details BufferedReader.
BufferedReader inDetails = new BufferedReader(new FileReader(inputFileDetails));
//Will hold values in warehouse arraylists.
String lineA = null;
String lineB = null;
String lineC = null;
//Will hold the details of each warehouse.
String line1 = null;
String line2 = null;
String line3 = null;
String line4 = null;
String line5 = null;
String line6 = null;
//Get the item count and total value for each warehouse.
while(inDetails.readLine() != null)
line1 = inDetails.readLine();
line2 = inDetails.readLine();
line3 = inDetails.readLine();
line4 = inDetails.readLine();
line5 = inDetails.readLine();
line6 = inDetails.readLine();
/**Assign the item count and total value to warehouse A.*/
//Cast.
int intLine1 = Integer.valueOf(line1).intValue();
double dblLine2 = Double.valueOf(line2).doubleValue();
//Assign the values.
this.intWarehouseAItemCount = intLine1;
this.dblTotalValueA = dblLine2;
/**Assign the item count and total value to warehouse B.*/
//Cast.
int intLine3 = Integer.valueOf(line3).intValue();
double dblLine4 = Double.valueOf(line4).doubleValue();
//Assign the values.
this.intWarehouseBItemCount = intLine3;
this.dblTotalValueB = dblLine4;
/**Assign the item count and total value to warehouse C.*/
//Cast.
int intLine5 = Integer.valueOf(line5).intValue();
double dblLine6 = Double.valueOf(line6).doubleValue();
//Assign the values.
this.intWarehouseCItemCount = intLine5;
this.dblTotalValueC = dblLine6;
/**Put the items back into the warehouses arraylists. */
//Add items to warehouse A.
while((lineA = inA.readLine()) != null)
warehouseAList.add(lineA);
//Add items to warehouse B.
while((lineB = inB.readLine()) != null)
warehouseBList.add(lineB);
//Add items to warehouse C.
while((lineC = inC.readLine()) != null)
warehouseCList.add(lineC);
}(this isn't the whole try statement its pretty long) -
How to use one pop up window for multiple buttons and input fields?
Hi Experts,
I have created a pop up window that will be opened from multiple buttons in the same view. There are input fields that the data will be populated from a pop up window. How can I set up which button that a pop up window is opened from? I also would like to populate the data from a pop up window to the input field next to a clicked button. There are 6 buttons and 6 input fields that share the same pop up window. I would very appreciate your responses.
Thank you,
DonHi,
Try creating 2 context attributes, one in your component controller and the other in the pop-up view. Bind the attribute of pop-up view to the component controller attribute.
In the main view, on click of every button set a unique code in the controller's context which helps you in identifying the button clicked. Since u have created a binding to the pop-up view attribute the value flows from the controller.
In the init method of your pop-up view, check the value of the attribute and based on that display which ever UI elements are required.
Eg:
On Button 1 click set value "B1", Button 2 value "B2" etc. In the init() of pop-up view u can check the values and perform the required operation:
if(("B1").wdContext().currentContextElement().getButtonIdentifier()){
else...{
Hope this helps you.

How do I use one audio jack as input and one as output?
On my MacBook Pro, if I get a USB-headphone connector (to add another audio port), will I be able to set one audio port as input and the other as output? To use the port coming out of the USB jack as a headphone jack, and plug a mic/output device into the computer's port?
I'm thinking about buying a "Sabrent USB External Stereo Sound Adapter". I have a preamp that is NOT an interface, and I want to be able to monitor what I'm doing so I can multitrack. But my MacBook only having one audio 1/8 inch jack makes it so I have to choose either input OR output...I'm hoping if I add an extra port via USB I'll be able to have one of each.
Thank you!Roger Wilmut1 wrote:

Yes, either way round. In System Preferences>Sound you can set the input and output ports separately.
Roger, the System setting have -Nothing- to do with the question being asked. Do you use Logic Pro audio software? If you did you would know Logic has it's own audio settings that run independently from the System audio. There's also the fact that Maverick has problems with "some" older USB 2.0 audio hardware. Basically, this is not a slam-dunk, that's why I suggested asking someone if they've used this combination before. Although... the USB audio device is cheap ($10) it might be worth it to try. Still.............**
** I question the wisdom of using cheap audio hardware on a computer that cost $1000+, software that costs $200 and then using the internal audio chip ($2) and an external monitoring device that costs $10. Defeats the whole purpose of using professional audio software. -

How can I stay on the same line when inputting values in the CLI?
The title is a bit vague i know :) but i have this issue which isn't really a problem but it would be better if I can solve it.
Intro)
I've made this simple addition (and more options but thats not relevant) application for kids in my spare time so that they can train their maths in school and compare their results with other students which is saved in the database using the hypersonic DB that comes with the JBoss application server.
Now so far so good, but i'm having an issue with the Scanner (I think, but i doubt its because of the CLI) , when i enter a number or text it works and exceptions will be catched etc but when i press the enter key without anything entered the input value wil be displayed a line below and that's not what I want. I want it to stay in the same line.
Sample CLI output:

I want the input to stay in the same line unless you have typed something. I feel silly for not knowing how to handle this.
Hm.. i'll tried to solve it myself but it seems that im unable to do that.
