callback function in UIR file is not a known function

[bmihura]

Whenever I call

LoadPanel (0, "CAL_ATP.uir", TEXT_PNL);

or

LoadPanelEx (0, "CAL_ATP.uir", TEXT_PNL, __CVIUserHInst);

in my CVI-generated DLL, I get this:

"The callback function, ClosePopup, specified in the UIR file, is not a known function. If you are using an external compiler, you must include the UIR callbacks object or source file in the executable or DLL."

I clearly have ClosePopup defined in my DLL. Even when I select "Embed Project .UIRs" under the "Build >> Target Settings..." menu, it still can't find ClosePopup. Other functions in my DLL are exported by export.h and used successfully by TestStand, but ClosePopup is not found by LoadPanel or LoadPanelEx.

How can I fix this?

When this happened to me once it was because I had a typo in the name of the function. (eg. ClosePopUp instead of ClosePopup) Ever since then I always let CVI generate the function prototypes for all callbacks in the UIR. Perhaps you could try editing the name slightly and let CVI go through the normal activities (of generating the CAL_ATP.h file; and the function prototype in your source code) to see if this clears the problem.

When this happened to me I had a problem where the function was actually present but the function was not in the UirCallbackTable.c.  This table was supposed to be automatically generated but it wasn't updated due to Clearcase File Configuration issues.  So check to see if your function is in UirCallbacTable.c.

I had it declared

void __stdcall ClosePopup (...);

in an attempt to make it export, when I should have stuck with

int CVICALLBACK ClosePopup (...);

like CVI generated for me. Now it works, thanks.

Hey Bruce,

Where are you these days?  I worked with you @ Symtx on JSF some time back.  Last I heard was that you were in CA.

Hiya Todd, I wasn't expecting to see you here! I'm back in CA for a few months.
