Problem with reading an unusual value from a FP-RTD-124 module.

I need help troubleshooting a FP-RTD-124 module. The problem I am having is that when I monitor the channel in FieldPoint Explorer, I get what appears to be a random number for the value. The numbers range from around -40C to +50C. I would expect the value to be consistent since it should be room temperature. FP Explorer also indicates that the channel status is "Successful!" and the rest of the channels are "Open RTD".
I am convinced that the RTD is wired in correctly to Channel 0 of the FP module. I have pulled the RTD out and measured consistently (using a multimeter) the resistance at ~107.4 Ohms which is what I would expect at room temperature. I have also tried changing the RTD and using diff
erent channels but I am still receiving those random numbers for the value. In addition, I made sure the channel was configured with the same TCR value as the RTD.
--- Additional Information ---
The RTD is a 4 wire Minco 100 Ohm Platinum RTD with a TCR=0.00385. I am using FieldPoint Explorer 3.0.2 (build 177). The network module is a FP-1600 connected directly to a computer using a x-over ethernet cable. The terminal base for the FP-RTD-124 is a FP-TB-1.
Any help would be appreciated.

Ken,
The first thing to do is to make sure the FP-RTD-124 is working correctly. Take a fixed resistor (100-200 ohms) and wire it between +Sense and -Sense. Add one jumper wire from +Sense to +Excite and a second one between -Sense to Com. Set the channel to the 0-400 Ohm range in FieldPoint Explorer. If the resistance is a steady, accurate value then the FP-RTD-124 is fine and you need to double check the RTD itself. If the reading is jumping around on the FP-RTD-124, then there is either an outside source of influence (make sure there are no connections to the V & C terminals on the terminal base) or the FP-RTD-124 has been damaged. If the FP-RTD-124 is behaving correctly, then check the lead to lead resistance on your RTD. It may be that one of the wires is
partially open that you did not catch when measuring with the DMM (assuming you used a 2 wire DMM).

Problem with reading consistent Language readings from device from within universal app

Friends,
I am working against a Class a wrote the other day. But I get unconsistent Uri results after pulling language and region on windows/Phone?!
As a beginner to all this, great of someone could tell me whats going on;
public void SetLanguageCode()
GeographicRegion userRegion = new GeographicRegion();
string LocalLanguageString = userRegion.CodeTwoLetter;
string LocalLanguage = Windows.Globalization.Language.CurrentInputMethodLanguageTag;
// string for NavigationUrl
string LocalLanguageID = LocalLanguage + "-" + LocalLanguageString;
Uri TestUriBase = new Uri("http://test.test.com/");
Uri UserUri = new Uri(TestUriBase, LocalLanguageID);
UriBuilder UrlBuild = new UriBuilder(UserUri);
Uri UriFinal = UrlBuild.Uri;
_languageCode = UriFinal.ToString();
Last field _languageCode returns "buggy" Uri on some regions/devices. How could you feed it a more static/solid language reading than above?
Thanks again for any pointers...
Regards, Kato.

Thanks for taking the time here;
To your question - its not correct.
But my problem is this - if I change my regional/keyboard settings to "Norwegian" - away from your US.
I get a string that is working and is correct;
http://test.test.com/nb-NO
But to get YOUR US Region to work - I need to tweak this line with commenting out the end;
string LocalLanguageID =
LocalLanguage; // +
"-" + LocalLanguageString;
And then its suddenly correct, but wrong if I change the region/language again to something "Scandenavian"...Then the final Uri for "_languageCode" is to short - like
http://test.test.com/nb
Which results in a "en-US Setting" - when hitting my MVC site from my App.
My MVC site that will answer to this "Uri" request from the app, has a fallback to "en-US", which is great if the Region/Language is missing/not offered. But now my final "_languageCode" field seems to change
its pattern based on different regions?!
And sometime it seems to give me a mix of region/language too?! Like this;
"http://test.test.com/en-US-NO"
So whatever pointers anyone has here?!
Thanks.
Regards, Kato.

I am facing a Problem with reading images from database

Hi everybody..
any help will be most appreciated, I am facing problem with reading images from database. I am pasting my code...
string connect = "datasource = localhost; port = 3306; username = root; password = ;";
MySqlConnection conn = new MySqlConnection(connect); // creating connecting string
MySqlCommand sda = new MySqlCommand(@"select * from management.add_products ", conn); //creating query
MySqlDataReader reader;
try
conn.Open(); // Opening Connection
reader = sda.ExecuteReader(); // Executing my Query..
while (reader.Read())
byte[] imgg = (byte[])(reader["Picture"]);
if (imgg == null)
pc1.Image = null;
else
MemoryStream mstream = new MemoryStream(imgg);
pc1.Image = System.Drawing.Image.FromStream(mstream);
It says Parameter not Valid... i am reading all the images from database

I agree with Viorel. You are getting the error because the format of the data is incorrect probably because the data was modify. It may not be the reading of the database the is incorrect, but the application that wrote the data into the database. You need
to compare the imgg array data with the data before it was written to the database to see if the data matches. I usually start by comparing the number of bytes which is easier to check then compare the actual to isolate which function is changing the
byte count.
An image is binary data. The standard VS methods for reading and writing data (usually stream classes) default to ASCII encoding which will corrupt binary data. The solution usually is to use UTF8 encoding instead of the default ascii encoding.
Ascii encoding with stream often aligns the data and adds extra null bytes to the end of the data which can produce these type errors.

Problem with READ Statement in the field routine of the Transformation

Hi,
I have problem with read statement with binary search in the field routine of the transformation.
read statement is working well when i was checked in the debugging mode, it's not working properly for the bulk load in the background. below are the steps i have implemented in my requirement.
1. I selected the record from the lookuo DSO into one internal table for all entried in source_packeage.
2.i have read same internal table in the field routine for each source_package entry and i am setting the flag for that field .
Code in the start routine
select source accno end_dt acctp from zcam_o11
into table it_zcam
for all entries in source_package
where source = source_package-source
     and accno = source_package-accno.
if sy-subrc = 0.
delete it_zcam where acctp <> 3.
delete it_zcam where end_dt initial.
sort it_zcam by surce accno.
endif.
field routine code:
read table it_zcam with key source = source_package-source
                                             accno = source_package-accno
                                             binary search
                                             transportin no fields.
if sy-subrc = 0.
RESULT = 'Y'.
else.
RESULT = 'N'.
endif.
this piece of code exist in the other model there its working fine.when comes to my code it's not working properly, but when i debug the transformation it's working fine for those accno.
the problem is when i do full load the code is not working properly and populating the wrong value in the RESULT field.
this field i am using in the report filter.
please let me know if anybody has the soluton or reason for this strage behaviour.
thanks,
Rahim.

i suppose the below is not the actual code. active table of dso would be /bic/azcam_o1100...
1. is the key of zcam_o11 source and accno ?
2. you need to get the sortout of if endif (see code below)
select source accno end_dt acctp from zcam_o11
into table it_zcam
for all entries in source_package
where source = source_package-source
and accno = source_package-accno.
if sy-subrc = 0.
delete it_zcam where acctp 3.
delete it_zcam where end_dt initial.
endif.
sort it_zcam by surce accno.
field routine code:
read table it_zcam with key source = source_package-source
accno = source_package-accno
binary search
transportin no fields.
if sy-subrc = 0.
RESULT = 'Y'.
else.
RESULT = 'N'.
endif.

Problem with QofQ and Null Values

Just converted from CF5 to CF7. Finally figured out what was
causing the error message :
"The value "" cannot be converted to a number" when running a
QofQ. It happens whenever there is a NULL (and I think a ZERO)
value in the QofQ. I'm using the QofQ in a seperate chart program.
The main query merges data from a store and a region table.
I'm doing a LEFT OUTER JOIN to combine the REGION with the STORE,
AND so that stores with NO SALES for a given day will show up as
ZERO. On the main report, when I don't use a QofQWhen grouping by
DAY or MONTH, I can test the value in the CFOUTPUT for NULL or ZERO
and display "0" or "N/A" on the report.
But when I try to chart it, using a QofQ to read in the
values from the main query, and format the numbers, I get this
error message. I've tried using the CAST function, using FLOAT,
DOUBLE, BIGINT, etc., but still get same error message.
The only way I could fix this is to add a WHERE statement to
the QofQ, that only includes sales values greater than ZERO. But
then, I have gaps in my chart because stores with NO SALES for a
given day or MONTH don't appear. Because they are removed from the
query. The whole point of LEFT JOINS is to include items with no
values (or NULL) values.
Does anyone know if it's possible to keep these values in a
QofQ? So that items (e.g., store locations in my case) with NULL or
ZERO values for some or all days or months can be charted? Even
with a ZERO value? I've read everything I can get my hands on
regarding QofQ, the CAST function, etc., but nothing seems to work.
Thanks for any help. (FYI, didn't have this problem with CF5. It's
QofQ could handle NULL or ZERO values without providing an error).

Well, I tried the IsNull function on the 3 SUM() values I was
calculating in my SELECT statement (on a LEFT OUTER JOIN QUERY),
and I STILL got another "cannot convert "" to a number" but this
time the error message was more direct, and pointed me to a DATE
field in my query, where I was SORTING AND GROUPING either by DAY
or MONTH (depending on what user selected on form).
In my QofQ, I'm not just reformating the integer SUM()
values, but also the date values. So, I applied the IsNull()
function to the DATE values in my main query. I still kept getting
errors. But after experimenting ((SQL Server BOL docs doesn't give
ISNULL() examples for DATE FIELDS, only NUMBER fields), I tried
putting the dates in SINGLE QUOTES in my IsNull() function, the
QUERY RAN. Then I wasn't sure WHAT date to enter, e.g., 1/1/1889 or
1/1/2001, etc.
Then, I discovered, after experimenting, that you cannot just
blindly enter ANY date when using IsNull in a date field,
especially if you are using CFGRAPH to chart the results by day.
You have to select a date within the date range the user selected,
so this means using the FORM.DATE (or URL.DATE) value from the
form. Here's the working example from my SELECT main query:
SELECT SUM(ISNULL(d.ttldb,0)) AS SumOfDB,
SUM(ISNULL(d.ttldbv,0)) AS SumOfDBV,
SUM(ISNULL(d.ttldbi,0)) AS SumOfDBI,
<CFIF '#url.reptype#' IS "DAILY">
ISNULL(d.depday, '#url.date1#') AS depday
<CFELSE>
month(ISNULL(d.depday, '#url.date2#')) AS TranMonth,
year(ISNULL(d.depday, '#url.date2#')) AS TranYear
</CFIF>
Then I discovered that whatever date was used in the URL.DATE
field (in my case it would be one of the two date field from the
form, and depended on whether you coded DATE1 or DATE2, the chart
would always show ZERO values for that date. So I tried putting the
IsNull() date values in the GROUP BY and ORDER BY statements, e.g.,
<CFIF '#url.reptype#' IS "DAILY">
GROUP BY ISNULL(d.depday, '#url.date1#')
ORDER BY ISNULL(d.depday, '#url.date1#') DESC
<CFELSE>
GROUP BY year(ISNULL(d.depday, '#url.date2#')),
month(ISNULL(d.depday, '#url.date2#'))
ORDER BY year(ISNULL(d.depday, '#url.date2#')),
month(ISNULL(d.depday, '#url.date2#'))
</CFIF>
And this worked. The report ran just fine, and the chart
charted every value correctly.
I guess you have to learn all the little "quirks" about CF7
and how it's QofQ and chart programs work. But so far, so good.
Thank you all for your help. Now I've got to update other old
CF5 programs that are returning errors when there are null values
from my LEFT OUTER JOIN queries. Will take some time, but at least
I know how to do it. Thanks to your help.
I really appreciate your time and efforts to help with this
issue.

How can I read an ID-value from the LMS and insert this into an URL?

Hi
Right now I am struggling with a little problem. Hopefully anyone here knows the answer. For the latest course I am building (Captivate 6), it is necessary that at one point the course reads an ID-value from the LMS. After that, this ID should be inserted into an URL.
To be more precisely: the ID must be read (getValue) from cmi.archive_id and inserted into an URL like that: http://.../archive.php?action=pdf&objectID=ARCHIVE_ID.
Unfortunately I am more of a designer und less of a javascript-maestro (well...I am a javascript-noob to be precisely), therefore I am pretty clueless how to do that. I tried a simple executed action (run Javascript: cpEIGetValue('cmi.archive_id'); and after that open URL http://.../archive.php?action=pdf&objectID=ARCHIVE_ID), but...well...that didn't work.
Any ideas?
Thanks a lot in advance

Think you'll find help looking at Jim Leichliter's website:
http://captivatedev.com/
He has great tutorials about JavaScript and also a widget that allows to enter a variable in URL's

Problem with reading config file

Hello,
I have problem with reading config file from the same dir as class is. Situation is:
I have servlet which working with DB, and in confing file (config.pirms) are all info about connection (drivers, users, passw, etc.). Everything work fine if I hardcoded like:
configFileName = "C:\\config.pirms";I need to avoid such hardcoding, I tryied to use:
configFileName = Pirms.class.getClassLoader().getResourceAsStream ("/prj/config.pirms").toString();but it isn't work.
My config file is in the same directory as Pirms.class (C:\apache-tomcat-5.5.17\webapps\ROOT\WEB-INF\classes\prj)
Also I tryied BundledResources, it isn't work fo me also.
Can anybody help me to solve this problem? with any examples or other stuff?
Thanks in advance.
Andrew

Thanks, but I am getting error that "non-static method getServletConfig() cannot be referenced from a static context"
Maybe is it possibility to use <init-param> into web.xml file like:
<init-param>
<param-name>configFile</param-name>
<param-value>/prj/config.pirms</param-value>
</init-param>If yes can anybody explain how to do that?
I need to have that file for:
FileReader readFile = new FileReader(configFile);Thanks in advance.

Java API to read the Encrypted Values from Windows Registry settings

Is there any Java API to read the Encrypted Values from Windows Registry settings ?
My Java Application invokes a 3rd party Tool that writes the key/value to windows registry settings under : “HKLM\Software\<3rdparty>\dataValue”.
This entry is in BINARY and encrypted with 3DES, using crypto API from Microsoft.
3rd party software to encrypt the data stored in registry it
either uses C++ code: and uses the call “CryptProtectData” and “CryptUnProtectData” or
If it is a .NET (C#) it uses the call “Protect” or “UnProtect” from class “ProtectData” of WinCrypt.h from the library “Crypt32.lib.
Note: The data is encrypted using auto-generated machinekey and there is no public key shared to decrypt the Encrypted data.
Since the data is encrypted using auto-generated machinekey the same can be decrypted from a .Net / C++ application using CryptUnprotectData or UnProtect() API of WinCrypt.h from the library “Crypt32.lib.
To know more about Auto-Generated MachineKey in Windows refer the links below
http://aspnetresources.com/tools/machineKey
http://msdn.microsoft.com/en-us/library/ms998288.aspx
I need to find a way in Java to find the equivalent API to decrypt (CryptUnprotectData) and Microsoft will automatically use the correct key.
But i couldn't find any informato related to Java APIs to enrypt or decrypt data using auto-generated machinekey.
Is there a way to read the encrypted data from Windows regsitry settings that is encrypted using the Auto-Generated Machine Key ?
Kindly let me know if Java provides any such API or mechanism for this.

If the symmetric key is "auto-generated" and is not being stored anywhere on the machine, it implies that the key is being regenerated based on known values on the machine. This is the same principle in generating 3DES keys using PBE (password-based-encryption). I would review the documentation on the C# side, figure out the algorithm or "seed" values being used by the algorithm, and then attempt to use the JCE to derive the 3DES key using PBE; you will need to provide the known values as parameters to the PBE key-generation function in JCE. Once derived, it can be used to decrypt the ciphertext from the Regiistry in exactly the same way as the CAPI/CNG framework.
An alternate way for Java to use this key, is to write a JNI library that will call the native Windows code to do the decryption; then the Java program does not need to know details about the key.
That said, there is a risk that if your code can derive the key based on known seeds, then so can an attacker. I don't know what your applicatiion is doing, but if this is anything related to compliance for some data-security regulation like PCI-DSS, then you will fail the audit (for being unable to prove you have adequate controls on the symmetric key) if a knowledgable QSA probes this design.

Problem with: select 'c' as X from dual

Problem with 'select 'c' as X from dual'
I get 2 different results when I execute the above with SQLPlus (or java) depending on the instance I am connected to. For one instance the result is a single character and for the other the character is padded with blanks to 32 chars in the SQLPlus window (and java).

OneKey Recovery 6.0. Problem with back up operating system from recovery cd'ies

Hello, i have problem with back up operating system from recovery cdies.
When i acceped start button to backup partition system i get an alert "space not enough"
I had linux before and i whant change it to windows back. i deleted all ext partitions. I have all unlocated space.I shouldnt have problems.
Please help me

I would use something like Partition Magic or Acronis Disk Director to first create a FAT32 partion for your C: Drive where your OS will go and be sure to leave 10GB or so unallocated for the secondary FAT32 Partition where your "factory image" will go.
You then create a Logical Drive with the unallocated space and make it hidden (PM or ADD will do this). Install your OS (preferably Windows XP if you want less problems) and then after you have setup everything the way you want (drivers, applications, etc), then use Acronis True Image to create your "factory restore" image on the hidden partition and activate the Startup Recovery Manager.
This is the way I do it and it works like a charm!

Stacked 100% bar chart - Problem with datatips for zero value data points

I have a stacked 100% bar chart that shows datatips in Flex 4.   However, I don't want it to show datatips for
data points with zero values.   Flex 4 shows the datatip for a zero value data point on the left side of a bar if the data point is not the first in the series.
Here's the code that illustrates this problem.    Of particular concern is the July bar.    Because of the zero value data point problem, it's not possible to see the datatip for "aaa".
Any ideas on how we can hide/remove the datatips for zero value data points ?        Thanks.

Problem with reading data from screen and inserting in table

hi ther,
im new to abap-webdyn pro. can anyone suggest how to read data from screen and insert into table when press 'ADD' button.
i done screen gui , table creation but problems with action. what the content of acton add.
is ther any link that helps me or tut??
thankx in advance!
regards

Hi,
Create a context node for the screen fields for which you want to enter the values with cardinality 1.1.....
Now in the layout of your view bind the screen input fields to that context node(attributes) to the value property of the input fields...
Now in the action of ADD button....
--> go the wizard and select the read node button and select the node which you have created it generates the auto code for you.....
for example if the node is contains aone attribute like MATNR
reading the node from wizard will generate the code as....
DATA lo_nd_matnr TYPE REF TO if_wd_context_node.
DATA lo_el_matnr TYPE REF TO if_wd_context_element.
DATA ls_matnr TYPE wd_this->element_matnr.
DATA lv_matnr TYPE wd_this->element_matnr-matnr.
* navigate from <CONTEXT> to <MATNR> via lead selection
lo_nd_matnr = wd_context->get_child_node( name = wd_this->wdctx_matnr ).
* @TODO handle non existant child
* IF lo_nd_matnr IS INITIAL.
* ENDIF.
* get element via lead selection
lo_el_matnr = lo_nd_matnr->get_element( ).
* @TODO handle not set lead selection
IF lo_el_matnr IS INITIAL.
ENDIF.
* get single attribute
lo_el_matnr->get_attribute(
    EXPORTING
      name = `MATNR`
    IMPORTING
      value = lv_matnr ).
here the variable lv_matnr will contain the entered value......
now you can use this value for further process.
Thanks,

Problem with reading special char from file

Hello Oracle community,
Got a problem when reading from a file. I am using a croatian keyboard and trying to read special charachters (ČĆŽŠĐ) from a file.

when no_data_found then
    utl_file.fclose(l_file);
end;But I keep getting this in dbms_output: ČĆĐ. For some reason it keeps skipping 2 chars Š and Ž. If I try to insert or update data the values are show correctly. What could be the cause of such a problem?
Best regards,
Igor

Hi Igor,
Looks like a NLS_LANGUAGE issue. Check the following threads:

Help! Problem with reading objects from file

I wrote a "Library" program for an assignment, and one of the requirements is that the library store all of its information to file upon exit, and reload this information from file when run.
Well, the writing to file part is working. I'm using a FileOutputStream object and an ObjectOutputStream object. I can tell from the file size of the .dat file that information is going into it.
But what I can't do is read from file. For that, I'm using a FileInputStream and an ObjectInputStream. I keep getting this exception:
java.io.EOFException
     at java.io.DataInputStream.readInt(Unknown Source)
     at java.io.ObjectInputStream$BlockDataInputStream.readInt(Unknown Source)
     at java.io.ObjectInputStream.readInt(Unknown Source)
     at Library.readDataFromFile(Library.java:350)
     at Library.<init>(Library.java:63)
     at LibraryDriver.main(LibraryDriver.java:6)I looked this exception up and it says it's thrown when a data input stream unexpectedly ends....But I am instantiating the input streams just before I try to read from file:
                        fileInStream = new FileInputStream(libraryFile);
               objInStream = new ObjectInputStream(fileInStream);
               Object[] objectArray = new Object[objInStream.readInt()];Both input streams have methods that "return the number of bytes that can be read from this file input stream without blocking". Just for kicks, I tried writing that number to the console.
For the FileInputStream, I get 404 bytes.
For the ObjectInputStream, I get 0 bytes.
So I guess it's a problem with the ObjectInputStream? Anyone have any suggestions as to how I can fix this, please?

Yep, here's the relevant code from the writeToFile() method:
                      for (int i = 0; i < libraryAuthors.length; i++) {
                    currentAlphaAuthorList = libraryAuthors;
                    for (int j = 0; j < currentAlphaAuthorList.size(); j++) {
                         currentAuthor = (Author) currentAlphaAuthorList.get(j);
                         objOutStream.writeObject(currentAuthor);
               objOutStream.flush();
               objOutStream.close();
