Well, i've setupped it using dialogs with the following code: 
// The global vars

HINSTANCE hinst_RE32Dll;
HWND h_RE;

// This is inside WinMain

hinst_RE32Dll = LoadLibrary("Msftedit.dll");

// And this is inside the DialogProc function

	case WM_INITDIALOG: 
		Main = hWnd;
		RE = CreateWindowEx(0, RICHEDIT_CLASS, 0, WS_VISIBLE | ES_SUNKEN |
			WS_CHILDWINDOW | WS_CLIPSIBLINGS | ES_MULTILINE | WS_CHILD |
		    ES_NOHIDESEL  |  WS_VSCROLL | ES_AUTOVSCROLL | ES_AUTOHSCROLL | WS_HSCROLL ,
			0, 0, 0, 0, hWnd, (HMENU) NULL, (HINSTANCE)GetWindowLong(Main,GWL_HINSTANCE), NULL);
		break;
Now, the problem is that when i start my program, i don't see any richedit control. Was wondering if anyone would have any idea why this happens and how to fix this.

In order to use a RichEditCtrl, you must at some point before attempting to display it call AfxInitRichEdit. If you don''t it won''t show up and/or will crash your app. So, try that.

Are you sure that is the right DLL? The MFC source loads RICHED32.DLL.


It depends on the version of the Rich Edit control youre trying to load.

AfxInitRichEdit() is an MFC macro. If you do not wish to use it, InitCommonControlsEx() is there to help you.

He''s not using MFC. I don''t think it likes a size of 0, 0. Try giving it a specific size. Also, the library is:

riched20.dll

Hello Alura, I''ve the same problem with MSFTEDIT. Could you post which value do you assign to the dwICC member of the INITCOMMONCONTROLSEX structure? Thank you really

Sorry I didn''t know. It''s only that when I try to create a window with the RICHEDIT_CLASS class name, if I load the Msftedit.dll library instead of Riched20.dll, CreateWindow (or CreateWindowEX) fails and GetLastError reports Class name not found, I think that Msftedit requires another class name, but user Alura says he/she got it with InitCommonControlsEx. I''ve tried with some dwICC member values, but I got nothing. Thank you very much.

Double check that LoadLibrary() does not fail. Remember that Msftedit.dll only exists on machines with WinXP SP1.

Yes, I have XP with SP1, and LoadLibrary does not return NULL. What do you mean with "double" check?

I meant make sure that LoadLibrary() does not return NULL.

Can you post the code you use to create the rich edit using Msftedit.dll?

If you use MSFTEDIT.dll, your code will only work on windows XP. Whats wrong with RICHED20.dll ?

Edit: on my compiler RICHEDIT_CLASS expands to "RichEdit20A"...
