Thread: why i cant use richedit 4.1

Hi i am tryng to change a program i wrote to use richedit 4.1. It compiles but doesnt work...The library was loaded successfully. Yet, the rich edit window just cant be created.

Code:

// rich edit control
	InitCommonControls();
	if(!LoadLibrary("Msftedit.dll"))
	return 0;

	GetClientRect(hwnd,&r);
	hEditCntl = CreateWindowEx(0,
								TEXT("RICHEDIT_CLASS"),
								NULL,
								WS_CHILD |WS_VISIBLE | WS_HSCROLL | WS_VSCROLL |
								ES_AUTOHSCROLL | ES_AUTOVSCROLL | ES_MULTILINE,
								0,
								0,
								r.right-r.left,
								r.bottom-r.top,
								hwnd,
								(HMENU)ID_EDIT,
								hinst,
								NULL);

			if(!hEditCntl)
		MessageBox(hwnd,"Not working","Not working",MB_ICONEXCLAMATION );

oops i wasnt aware it was for unicode application. What about rich edit 3.0? I tried loading the riched20.dll library and register with the classname "RICHEDIT_CLASS". It didnt work either.

Oh yes it finally work. Now i can start to the functions of rich edit. Thanks alot.

But just one more question. I have a menu for the parent window of the rich edit control. Each time i selects the undo function from the menu, it does not execute the undo action on the control if i use the window handle from the WM_COMMAND message handler, i.e hwndCtl. I have to use the window handle i store in my mainFrame class when i first create the control for the undo action to work. Is there something wrong with my HANDLE_WM_COMMAND message handle?

HANDLE_WM_COMMAND calls this function:

Code:

void mainFrame::mainWindow_onCommand(HWND hwnd, int id, HWND hwndCtl, UINT codeNotify)
{
	switch(id)
	{case ID_FILE_EXIT:	DestroyWindow(hwnd);
						break;

	case ID_FILE_NEW: Edit_SetText(hEditCntl,NULL);
		              break; 

    // function to handle notify message from rich edit control
	case ID_EDIT: edit_onCommand(hwnd,id,hwndCtl,codeNotify);
		                 break;

// I CANT USE hwndCtl FOR THIS CASE
	case ID_EDIT_UNDO: Edit_Undo(hEditCntl);
					   break;

	default: FORWARD_WM_COMMAND(hwnd,id,hwndCtl,codeNotify,DefWindowProc);
	}

}

ah yes...I realised my mistake. Thanks for saving my day again.
