Working with multiplie Panels And C Files

[Kobi_K]

Hi !

I have a general question...

I'm workign with CVI 9.1 , and i have serveral C files .

At the main.c file I'm loading all my panels for ex Panel Name - PREF, Panel Handle - panelPrefHandle

At the service.c file I'm trying to use GetCtrlVal(panelPrefHandle,....,...);

                                              OR  GetCtrlVal(PREF,....,...);

At service.c i'm including #include "main.h"

Still I'm getting the error :

NON-FATAL RUN-TIME ERROR:   "Service.c", line 677, col 29, thread id 0x00000D30:   Library function error (return value == -42 [0xffffffd6]). The handle is not a panel handle

so my question is how can i pass panel handel over serveral c files ?

Hi,

you need to include the include file of the panel: if you build and save a panel in the UIR editor, a corresponding *.h file is generated; you need to include this file in the *.c file which will access this panel, because the panel name etc. are defined in the panels' include file.

Hth, Wolfgang

I know thats what i did .

But still it doesn't recognize the panelHandle

Declaring you panel handle as a global works, you can also just pass the handle to the function as an integer:

yourFunction(int PanelHandle)

and use it inside your function as needed.
