How to call a dll which has one VISA name as input

Hi there,
The Labview application builder can generate a dll file from a vi which is a simple serial comunication program using VISA name as one control.
The problem is how to call the dll file in Labview which has a VISA name as INPUT?
Thanks!
George

I would suggest modifying the LabVIEW VI so that the input is a string control instead of a visa control. The LabVIEW application will work the same and there is no need for any casting. All visa VIs can take a string as an input. Then when you recreate the dll make the input a string. Then you can easily pass a string to the dll from any API.

How to call a function which has a cursor

hey folks I have a function which has a cursor,,like this
CREATE OR REPLACE FUNCTION EMPCU RETURN VARCHAR
AS
CURSOR EMPC IS
SELECT LNAME,SALARY,SSN
FROM EMPLOYEE
WHERE DNO IN(4,5);
EMPV EMPC%ROWTYPE;
BEGIN
OPEN EMPC;
LOOP
FETCH EMPC INTO EMPV;
EXIT WHEN EMPC%NOTFOUND;
/*DBMS_OUTPUT.PUT_LINE(EMPV.LNAME||' '||EMPV.SALARY||' '||EMPV.SSN);*/
RETURN EMPV. LNAME ||' '|| EMPV.SALARY||' '||EMPV.SSN;
END LOOP;
CLOSE EMPC;
END EMPCU;
Above function created successfully. I called above function like this
DECLARE
ENAMESAL VARCHAR2(70);
BEGIN
ENAMESAL:=EMPCU();
DBMS_OUTPUT.PUT_LINE(ENAMESAL);
END;
Function is called and function is returning only one row instead of 7 rows. Actually cursor is supposed to return 7 rows but it is returning only one row. Is there any snytax to call a function which has a cursor. So experts please tell me where I have to make changes. I would be very thankful to you

Well, you've told the function to RETURN within the loop, so after the first record in the loop, the function returns as you've instructed it.
You would need to change your function to accept a specific input from the EMP table and then do a look up for that specific record and return the values you wanted, and wrap the function call in a loop in your anonymous block.
Or you could just have the anonymous block like this....
BEGIN
   FOR X IN
      SELECT EMPV. LNAME ||' '|| EMPV.SALARY||' '||EMPV.SSN AS Line_Data
      FROM EMPLOYEE
      WHERE DNO IN(4,5)
   LOOP
      DBMS_OUTPUT.PUT_LINE(x.Line_Data);
   END LOOP;
END;

Write a query for which has its field name as input parameter

Hi All,
I need to write a query for SSRS report. StartDate, EndDate and ChangedField are the input parameters.
Let's consider that we are taking employee details. The table contains lot of fields like emp name,add1,add2,city,state,country,designation,rank etc. We have almost 30 fields are there. These field name are coming as input parameter "ChangedField"
. I need to show the records which belong to the start date and end date also data change for the field which is given in the input parameter "ChangedField". That meand If I give ChangedField="city", we need to check for data which
has been updated with new City name in the given time period.
Please suggest.
Regards,
Julie

Hi Julie,
Per my understanding that you have many fields in the table to be displayed in the report, some of the fields will always show and others should be hide and show based on the selection of the parameters which include the columns names, right?
By default, we can't display columns dynamically in the report automatically without insert this column in the report before. So, in your scenario, I will suggest you to add all the columns in the reports first and then add show/hide expression on
the column visibility based on the selection of the parameter "ChangedField", when some of the fields selectted they will be display, otherwise they will be hidden. For the fields which you want to be always displayed will not need to add the expression
in the column visibility.
Details steps about how to acheive this, please referencet to the article below:
Displaying Dynamic Columns in SSRS Report
If you still have any problem, please feel free to ask.

But how do i create element if a column name is kind of dynamic. Please help. I cannot Rename/change the Column in SQL Query. Please let me know If I could handle this whole logic in BI Publsiher.

How to call LabVIEW dll from ATL COM dll

I have tried to call simple LabVIEW 8.6 Dll from win32 test application, class Library.
I have include LabVIEW generated SharedLib.h file and SharedLib.lib file in the test application which I created as simple win32 console project and also from win32 class Library. I was sucessfully able to call my LabVIEW dll funtion.
But when I create ATL COM project and try to add SharedLib.h file and SharedLib.lib file I used to get following erors
Error 1 error C2733: second C linkage of overloaded function 'StrCatW' not allowed d:\program files\national instruments\labview 8.6\cintools\extcode.h 463
Error 2 error C2733: second C linkage of overloaded function 'StrCpyW' not allowed d:\program files\national instruments\labview 8.6\cintools\extcode.h 464

Error 5 error C2733: second C linkage of overloaded function 'StrCmpNW' not allowed d:\program files\national instruments\labview 8.6\cintools\extcode.h 467
these many errors.
Will some one explain me how to call LabVIEW dll from ATL COM dll.
Thanks & Regards,
Jay

I also had this problem. My application is unicode-aware, but I was attempting to link it to a library with primitive C-string arguments. You could dynamically load the DLL as suggested (more work), modify the header files (really not recommended), or if you are feeling lucky you could try fooling the compiler, as I was successfully able to do in Visual Studio 2010, by steering the preprocessor around those functions (assuming you're not using them, of course -- otherwise this probably wouldn't work):
// prepare for NI extcode.h inclusion. avoid linker errors for this project.
#define StrCatW(a,b)     IgnoreLinkError_StrCatW(a,b);
#define StrCpyW(a,b)     IgnoreLinkError_StrCpyW(a,b);
#define StrCpyNW(a,b,c) IgnoreLinkError_StrCpyNW(a,b,c);
#define StrCmpW(a,b)     IgnoreLinkError_StrCmpW(a,b);
#define StrCmpNW(a,b,c) IgnoreLinkError_StrCmpNW(a,b,c);
// header file for my LabView-built DLL (ASCII single-byte character arguments)
#include <MyLibraryHeader.h>
// clean up afterwards, put things back to 'normal'
#undef StrCatW
#undef StrCpyW
#undef StrCpyNW
#undef StrCmpW
#undef StrCmpNW

How to call the DLL writing in Vb6.0 from testsatnd?

Hi,
I want to call a dll writting in VB6.0 from teststand. But as i see from the "Step Setting" in teststand, only the C/C++ Dll can be selected in the "adapter" type. I try to use this one as my adapter to call my VB6.0 dll, in result, there is no function can be seen in the "function" tab in teststand.Anyone know how to call the DLL writing in Vb6.0?
Solved!
Go to Solution.

Hi Ivan,
Just to be sure that your DLL is not wrong
you have check if all functions are well and present.
There is tool called "Dependency Walker" You can download it at http://dependencywalker.com/ .
With it you can look "inside" your dll
If you will see your functions there, you will see them (in my case !!always!!) in TestStand, too.
Hope this helps

How to handle user preference which has "_" and " " in the name

Hi Experts,
I have a question how to handle value which has like "_" and "space" etc in user preference.
If setting "a_b-c d", I could not retrieve this because it's escaped in database.
So this code can't get value even though I can set it.
Is there any restriction of name? Is there any documentation how to code user prefernece which has non alphabet and number in the name?
I know it's possible to handle the data like adding escaped data. But I don't think this is the best way to retrieve the data. Because nobody confirm it's not problem in the future.
Could you tell me the best way to get these user preference?
Thanks in advance,
Masaaki Tada

Plumtree recommends that user preference names have only alphanumeric characters in them (a-z, A-Z, 0-9). Any non-alphanumeric characters will be encoded by the EDK.
I strongly suggest that you change your user pref name to something that's alphanumeric. However, if that is not possible, you can use the following workaround: in the web service editor, enter the encoded name for the user pref. There are several ways to get the encoded name.
One way is to encode the pref manually, yourself. Plumtree uses the %u encoded format: each non alphanumeric character is converted into %uxxxx, where xxxx is the Unicode representation of the character. For all ASCII characters, just look at the ASCII hex chart. For example, character "-" has a hex value of 2d. So, a preference name "jane_pref" would be encoded to "jane%u002dpref", and you'd enter the latter value on the preferences page in the web service editor.
The other way to find out the encoded value is to set a preference programmatically and use the HTTP tunnel tool to look at HTTP traffic between the portal server and remote server. The remote server will be sending a HTTP header to the portal server (the header name will probably be CSP-User-Pref) and inside the header you should see the pref name, encoded with %u. Just copy it out of there and into the web service editor.
Hope this helps,
Jane

Can not create an object for my c# form dll which has an ActiveX control

I want to create an object in teststand for my C# form dll which has an ActiveX Control . but the error says ActiveX control can not be instantiated because the current thread is not in a single-threaded apartment. can someone help to solve the problem?
Thanks.

Two options:
1) put the step in a subsequence and use the sequence call "New thread" option with the advanced setting "Use single-threaded Apartment". Put a wait step immediately after the sequence call to wait for the new thread.
2) Inside of your dll, using .NET APIs create a new thread initialized as STA and call your code from that. Have the original thread wait for the new thread to finish running your dialog code.
Hope this helps,

How to use the DLLs which created from c++ in Java?

And How to use the DLLs which created from JNI in C++?

Huh?
Are you asking how to do JNI - you should read the tutorial.
Are you asking how to load it - then use System.loadLibrary()
Are you asking what to do with the output from javah - put it in a C file and write some code, compile it into a dll.

How to upload a file which has more than 999 line item through BDC ?

Hello Techards
Hi to all
Can any body tell me how to upload a file which has more than 999 line item through BDC for traction F-02 ?
Thanks in advance.
Shovan

Hello Shovan,
You split it up to post two accounting documents with the help of a "suspense" a/c.
Say, you have to post the following line items below:
line 1 - dr. - GL a/c X - $1000
line 2 - cr. - GL a/c Y - $1
line 3 - cr. - GL a/c Y - $1
line 1001 - cr. - GL a/c Y - $1
You cannot post the above as a single doc in SAP (because of technical reasons), so you need to break it up into 2 documents as below:
Doc1
line 1 - dr - GL a/c X - $1000
line 2 - cr - GL a/c Y - $1
line 3 - cr - GL a/c Y - $1
line 998 - cr - GL a/c Y - $1
line 999 - cr - SUSPENSE a/c - $3
Doc2
line 1 - dr - SUSPENSE a/c - $3
line 2 - cr - GL a/c Y - $3
Note that there is no incorrect impact on accounting as first we credit suspense a/c by $3 and next we debit the same suspense a/c by $3 as a result the effect is nil. Similarly, we credit $997 to GL a/c Y (which is less by $3) in the first doc which is compensated by the second doc by crediting the shortfall of $3.
Hope this helps,
Cheers,
Sougata.
