InstallShield 2018 » InstallScript Language Reference
Tip • The CallDLLFx function is supported only for compatibility with scripts created in previous versions of InstallShield. Consider using the more flexible method described in Calling a .dll File Function instead of using the CallDLLFx function.
The CallDLLFx function calls a function within a specified .dll file.
Syntax
CallDLLFx ( szDLL, szFunction, lvValue, svValue );
The function called must use the following fixed definition, where hwnd is the main window handle for the main InstallShield window:
LONG APIENTRY YourFunction (HWND hwnd, LPLONG lpIValue, LPSTR lpszValue);
