SUMMARY

Within a standard Windows dynamic-link library (DLL), the instance handle of the current .DLL is passed to the function through the LibMain() API function. In a FoxPro-link library (FLL), you do not have access to the LibMain() function.

In FoxPro versions 2.x, you have access to a global variable called Inst. Within this global variable is the current instance handle. However, if you are using Visual FoxPro version 3.0, you can use the FoxPro API call _GetAPIHandle() to obtain the the current instance handle.

MORE INFORMATION

FoxPro 2.x

In FoxPro version 2.x, to obtain the current instance handle, the variable Inst must be declared as follows: 
     HINSTANCE Inst;
Once this is done, the current instance handle will be stored in the global variable Inst.

Visual FoxPro

To obtain the current instance handle in FoxPro version 3.0, use the the FoxPro API call _GetAPIHandle(). For more information on this API function see the _GetAPIHandle() topic in the Visual FoxPro on-line help file.
