Problem with GetCtrlVal(), RUN TIME ERROR Compiling a CVI 5.0 Source with CVI 8.0

[ThiloV]

Hello everybody,

I have little problem. We got the new 8.0 version of CVI.

Today I wanted to compile an old source written in CVI 5.0.

But now there appear several NON FATAL RUN TIME ERRORS:

GetCtrlVal (panelHandle, str_module[mod].ctrl_filename, str_module[mod].filename);

str_module[mod].ctrl_filename is equivalent to an control ID on my GUI

The error wich appears is:

return value -13

Invalid control ID

It is strange! In CVI 5.0 everything worked correct.

What is the problem? Can you help me?

Maybe it is a problem in the header file.

Is it possible to create a new header of my .uir File.

Hi ThiloV,
   The prototype for GetCtrlVal is:
     

           int GetCtrlVal (int Panel_Handle, int Control_ID, void *Value);

   so Control_ID is meant to be integer.  How is defined str_module[mod].ctrl_filename ?    You can put there a MACRO, but not a string. 

   If, instead of the variable, you put the number of your control, generated by CVI and stored in .h file for uir resource, do you still get the error?

   Please, let me know!!!!

Hi Graziano,

thank you for your reply.

str_module[mod].ctrl_filename  is an integer. It is a part of a struct in my source.

>>If, instead of the variable, you put the number of your control, generated by CVI and stored in .h file for uir resource, do you still get the error?

I tried this, but I still get the error. I don't understand what is wrong.

Do you have an idea?

Hi Thilo,
   I'm really sorry, but I've no idea of what's going on......

   Can you post some files? Especialy the .h (header) containing the user interface controls IDs, and can you post the chunk of code where you define the structure containing str_module[mod].ctrl_filename definition?? I mean the typedef struct ....

   Unfortunately, I can't assure you this may help.....

    Greetings!

Hello Graziano,

Thank you for your help. In the mean time I found the mistake.

It was a problem with the Panel Handle.

But it is very strange that CVI 5.0 never showed this error.

Bye

OK!
   It's always useful to report strange behaviours!

   Have a nice day!
