Hi,

I've got a text program I'm working on. It has game like print. But I 
want to be able to copy to the clip board and paste from it in my 
program etc. I'm using Windows 7. I have used a bit of Ubuntu in the past.

Well, it doesn't matter what you've used in the past :-)

Thanks for the reply Jimmy.

I was thinking more like SDL (has SDL_GetClipboardText, 
SDL_SetClipboardText, 
http://wiki.libsdl.org/moin.cgi/CategoryClipboard). I'm not sure I would 
be able to get Windows CE Clipboard stuff working for me.

Search engines often return Windows CE results for API searches.

Here's the clipboard developer documentation for full Windows versions:

Here's an example I've quickly put together for you:

import std.stdio;
import core.stdc.string;

extern(Windows) {
    void* GetClipboardData(uint);
    bool OpenClipboard(void*);
}

void main() {
    if (OpenClipboard(null)) {
        auto cstr = cast(char*)GetClipboardData(1);
        if (cstr)
            writeln(std.conv.to!string(cast(char*)cstr[0..strlen(cstr)]));

The other way is a bit more complicated.
Try this:

   void* GetClipboardData(uint);
   void* SetClipboardData(uint, void*);

       EmptyClipboard();

       auto mystr = "my data";
       void* handle = GlobalAlloc(2, mystr.length + 1);
       void* ptr = GlobalLock(handle);
       memcpy(ptr, toStringz(mystr), mystr.length + 1);

Thanks so much Jimmy. You put in a bit of effort. :-)

I just added this code to my general library:





extern(Windows) {
    bool OpenClipboard(void*);
    void* GetClipboardData(uint);
    void* SetClipboardData(uint, void*);
    bool EmptyClipboard();
    bool CloseClipboard();
    void* GlobalAlloc(uint, size_t);
    void* GlobalLock(void*);
    bool GlobalUnlock(void*);
}

string getTextClipBoard() {
    if (OpenClipboard(null)) {
	   scope( exit ) CloseClipboard();
        auto cstr = cast(char*)GetClipboardData( 1 );
        if(cstr)
            return cstr[0..strlen(cstr)].idup;
	}
	return null;
}

string setTextClipboard( string mystr ) {
	if (OpenClipboard(null)) {
		scope( exit ) CloseClipboard();
		EmptyClipboard();
		void* handle = GlobalAlloc(2, mystr.length + 1);
		void* ptr = GlobalLock(handle);
		memcpy(ptr, toStringz(mystr), mystr.length + 1);
