<![CDATA[Not able to load dll]]>Hi,

I am not able to load dll. "bool okLoad = mylib.load();" is returning false.

I have tried following, but none of them are working:

1.) QLibrary mylib("abc.dll");
bool okLoad = mylib.load();

2.) QLibrary mylib("C:/Simulator/Package/trunk/Simu/abc.dll");
bool okLoad = mylib.load();

3.) I have added "LIBS += abc.dll " in .pro file too

I don't know I am not able to load dll.

Thanks in advance

As is said if not all symbols are C-exported the compiler (and probably some specific settings) need to match in order to successful load the library!
Where did you get the DLL from?

"Cannot load library abc.dll: This application has failed to start because the application configuration is incorrect. Reinstalling the application may fix this problem."

I can see that corresponding header file have C-exported methods.

And please provide more info:
What is this DLL for?
Does it contain C-exported methods? If not is the compiler version the same?
What does QLibrary::errorString() return after the you have called load()?
