Can't find what? What is the exact error message that you see?

[ForNow]

Sorry don't know the pretag for the linker but you can see the output thing is I opened up VS command prompt and did DUMPBIN /EXPORT and I can see those functions exported and I did put that .lib library path (its Windows SDK 8.0) in VC++ directories for the library directories

 Creating library msvc.debug.AMD64.obj\\hengine.lib and object msvc.debug.AMD64.obj\\hengine.exp

Did you actually include the .lib file in your linker inputs in the project?

[ForNow]

It's a nmake project so All I do in the project properties on the left pane is VC++ directories I input the path the lib is in the library directories the thing is I have used other Windows Sdk API however this is in windows SDK 8.0 to I had to download and include the header path and library path after I installed Windows SDK 8.0

I don't know nmake. But somewhere in the nmake file you need to tell the linker which libraries to include. Just giving the path to the directory will not work, it does not scan every file looking for exported functions.

Thing is I have added Windows SDK API into this project such as SendMessage to communicate with the windows program I wrote But I think you are right

Well, as I say, the linker will not attempt to guess which .lib file it needs to include.

Going by the page at https://msdn.microsoft.com/en-us/library/windows/desktop/hh706898(v=vs.85).aspx You will need to include Synchronization.lib in the nmake file/settings with the other .lib files (inlcuding the path, im not too up to date with nmake)

IS there a way to do this with #import directive in the source code

[ForNow]

I found it in addition to including the path there was LIB = $(LIBS) user32.lib I added synchroninzation.lib the user32.lib allowed me to use SendMessage without a problem thanks

No, the #import statement imports types from a type library at compile time. You can use the #pragma command as described at: comment (C-C++)[^].
