hey, is there an easy way to get the text of a CSting into the clipboard? I cant seem to find a way. Or is it more envolved?
thanks

Easy only in VB.

Look at MSDN[^] for a C/C++ solution. (see the samples)

CSharedFile sf(GMEM_MOVEABLE | GMEM_SHARE | GMEM_ZEROINIT);

// Place clipboard data in the shared memory file
sf.Write(sString, strlen(sString)); 
	
if (sf.GetLength() > 0) {
	// Put the data on the clipboard
	OpenClipboard(AfxGetMainWnd()->GetSafeHwnd());	
	EmptyClipboard();
#ifdef _UNICODE
	SetClipboardData(CF_UNICODETEXT, sf.Detach());
#else
	SetClipboardData(CF_TEXT, sf.Detach());
#endif
	CloseClipboard();
}

Calling convention in a DLL

What programming tools do you use? MFC makes working with clipboard very easy.

I'm using LoadLibrary and GetProcAddress to pull a function from a DLL. This is working okay but when I call the function, I get this from the Debug Library:

"The value of ESP was not properly saved across a function call. This is usually a result of a calling function declared with one calling convention with a function pointer declared with a different calling convention."

Now I know this means that I'm using the wrong definition for my function pointer. Unfortunately, I don't know what the exact definition should be (and the person who can tell me is on holiday!).

I know that it's two strings in and an integer return. I've tried:
typedef int (*FUNCPTR1) (LPSTR Key, LPSTR Licensee);
typedef int (*FUNCPTR1) (LPCSTR Key, LPCSTR Licensee);

neither of which work.

So does anyone have any idea how I can extract the correct definition from the DLL?

May the problem come from a mix between C and C++ ?
if so, __cdecl may help.

Isn't __cdecl for in the DLL? I know it's being exported with the right name.

Where would I put __cdecl in the calling program?

In dll
void _stdcall aa(){};
In app
void(_stdcall* )() tmp = GetProcAddress(..);

i think above will pass

If I try any variation on this theme, I get "Syntax Error : ')'" on the closing parenthesis after _stdcall*

i'm sorry , should like this

void(_stdcall* tmp)() = GetProcAddress(..);
OR
typedef void(_stdcall* funType)();
funType tmp = GetProcAddress(..);

That's the answer I'm looking for. Thanks, that works great!

The fastest solution to this problem is by removing the "/GZ" from the "Project Options" listbox
