Standard windows libraries vs. EE

Hey there!

I needed a function that copies text to clipboard and at first I didn't realise there is ClipSet() in the engine so I made my own function following a tutorial.

This works perfectly when compiled and used as an independent console app:

Code:

#include <Windows.h>

void SetClipboard(char *text)

{

    const size_t len = strlen(text) + 1;

    HGLOBAL hMem =  GlobalAlloc(GMEM_MOVEABLE, len);

    memcpy(GlobalLock(hMem), text, len);

    GlobalUnlock(hMem);

    OpenClipboard(0);

    EmptyClipboard();

    SetClipboardData(CF_TEXT, hMem);

    CloseClipboard();

}

but when I tried to put it in a header file and then include it into one file in my EE project where I needed it, this happened:

Code:

I know this function is useles since ClipSet() is already there but I'm simply wondering why is it not working... This happened to me before with different functions but I simply worked my way around like this time.

#include doesn't play nice in the code editor. You have to add it in the application properties, I believe.

Kiekos · 04-27-2014 10:43 AM

Unfortunately I'm not using the code editor but VS 2012.

Btw, I've also tried including only declaration of the function in the header file and the definition was in a .cpp file that was added to the project.

This setup works for most of my functions, but not this one... Same errors, so I guess it doesn't have anything to do with the way I include it, either way it explodes when compiled.

EDIT: And as you can see, none of the errors points at my function! Each of them points at different standard windows library saying that something's missing there or is undefined.

did you paste "#include <windows.h>" before EE headers include? If not, try to do that.

Kiekos · 04-28-2014 10:14 AM

Thanks for the hint, but unfortunately that doesn't seem to be the problem. Current setup looks like this:

Code:

//functions.h

#ifndef FUNCTIONS

#define FUNCTIONS

void SetClipboard(char *text);

#endif

and this functions.h file is included in the main.h file, which is then included in all .cpp files. The definition is in separate .cpp file that is only added to the project.

Code:

//functions.cpp

#include "stdafx.h"

#include <windows.h>

void SetClipboard(char *text)

{

    const size_t len = strlen(text) + 1;

    HGLOBAL hMem =  GlobalAlloc(GMEM_MOVEABLE, len);

    memcpy(GlobalLock(hMem), text, len);

    GlobalUnlock(hMem);

    OpenClipboard(0);

    EmptyClipboard();

    SetClipboardData(CF_TEXT, hMem);

    CloseClipboard();

}

and that's the whole file. But even if I put #include <windows.h> as the first header in the main file, same errors occured...
