custom action - calling DLL

[dmetzler]

I have set up a custom action to call the SHChangeNotifyA function in the shell32.dll.

However, when I attempt to build the project with the custom function, I get an error:

The function block "::SHChangeNotifyA" must be in the form "Module::Function" with an error code of -3713

I cannot find any specific information on how to correct this.

Has anyone seen this before, and if so, how do I correct the problem?

Regards,

Don Metzler

What are your (Standard DLL?) action settings?

Does it work if you use SHChangeNotify instead of SHChangeNotifyA?

No - the same error occurs.

Strange that the signature line doesn't have shell32.dll at the front; a similar example (except with no condition) seems to work at this end:

I deleted the existing item and recreated it with the same parameters. The new one inserted the "shell32:" as a prefix to the function name.

Okay, good---is it working now?
