I have no idea about this platform. So all I can say is for the 'real' MFC.

But if you have a CComboBox, you can use AddString(), or CB_ADDSTRING as a message to the control.
For loading all entries at once like a menu, you could load the menu, get the texts, and call AddString()with it in a derived class.

Run Dll

I've created an MFC-dll.

Now I want to execute the app inside the dll. Which program do I have to use for that? Rundll.exe, Rundll32.exe (what's the difference)?

Or are there any other programs?

This is what I did (and it didn't work Smile | :)

):
Inside vc6 I pressed ctrl-f5 to run the app, a popup appeared requesting a dll-executer. I browsed to windows/rundll32.exe and selected it. But the dll was never executed.

What am I doing wrong?

syntax : rundll32 DllName,FunctionName [Arguments]

Where FunctionName is an entry-point (any function) with the following prototype :

void CALLBACK EntryPoint(
  HWND hwnd,        // handle to owner window
  HINSTANCE hinst,  // instance handle for the DLL
  LPTSTR lpCmdLine, // string the DLL will parse
  int nCmdShow      // show state
);

Interesting stuff is that WinMain() has this prototype too, but this was easily predicted.

MSDN doc[^]

rundll.exe is the former 16-bit counter part (now legacy).

If the DLL is an in-proc COM component, you may instead use the DllHost.exe surrogate process, though it works differently.

I'm calling rundll from VC6.

So the settings are:

Executable for debug session:
c:\windows\rundll32.exe

Working directory:
empty

Program arguments:
empty

Remote executable and path name:
empty

Where do I have to put the functionname?
Is it fn() or just fn without ()?
I don't have to state the dll-name, isn't it?

btw:
I've tried several combinations, but none of them work.
I can switch to release version if debug doesn't work.

The functionname should be put in the Program arguments field, (may be with additional quotes to make sure that space chars are properly interpreted).

Your operating system already uses many times rundll32.exe xxx, so I guess this could help you figuring it out. Just do a search in the registry!

I entered this: ,functionname
whithout quotes or brackets, like it's defined in .def file.

Now rundll says that it cannot find the path to other dll's needed by my dll (mfc dll's I guess). But they are probably in windows\system directory.

I've also tried to enter my projects pathname, but that doesn't make any difference.

and another question:
I saw once that dll's are called by the RunDll-function, instead of the WinMain-function for regular apps. Is that true? Can't find it anymore.

Why my code can't print the bitmap?

These are my codes about printing bitmap:

	if (printDlg.DoModal() ==IDOK)<br />
	{<br />
		dc.Attach (printDlg.GetPrinterDC());<br />
		DOCINFO di;<br />
		memset(&di,0,sizeof(DOCINFO));<br />
		di.cbSize =sizeof(DOCINFO);<br />
		di.lpszDocName ="Í¼Ïó´òÓ¡";<br />
		CString filename="MONEY.bmp";<br />
     HBITMAP bmp=NULL;<br />
bmp=(HBITMAP)LoadImage(NULL,filename,IMAGE_BITMAP,0,0,LR_LOADFROMFILE|LR_CREATEDIBSECTION);<br />
<br />
	  CBitmap bitmap;<br />
	  bitmap.Attach (bmp);<br />
	  BOOL bPrintingOK = dc.StartDoc(&di);<br />
	CPrintInfo Info;<br />
    Info.m_rectDraw.SetRect(0,0, dc.GetDeviceCaps(HORZRES), dc.GetDeviceCaps(VERTRES));<br />
	StartPage(dc);<br />
<br />
	  <br />
      CDC dcMemory;<br />
      dcMemory.CreateCompatibleDC(&dc);<br />
	  		<br />
	  dcMemory.SelectObject(bmp);<br />
	  BITMAP bm;<br />
	  bitmap.GetBitmap(&bm);<br />
		<br />
dc.StretchBlt (0,0,bm.bmWidth,bm.bmHeight,&dcMemory,0,0,32,32,SRCCOPY);<br />
	  EndPage(dc);<br />
	  EndDoc(dc);<br />
	DeleteDC(dcMemory);<br />
   dc.Detach ();<br />
	}<br />
	DeleteDC(dc);<br />
<br />

The compiler told me there are 0 errors,but I can't see the bitmap appear on the paper after the program is executed.Why? Frown | :(

This is the classic case of trying to print a device-dependant bitmap (DDB). What you need to do is to convert the bitmap to a device-independant bitmap (DIB) before you print it. There are articles on www.codeguru.com[^] describing it and probably also here somewhere...

Look at the bitmap section[^] at codeguru for some code.
