You need to call AfxInitRichEdit to initialize rich edit control for app. Call this function in your application.

Hi Prasad, Thansk for the responce. I called AfxInitRichEdit(); in my Dialog, I am getting error C2065: 'AfxInitRichEdit' : undeclared identifier Dialog which I have created is from win32 Application and not from MFC. Can u please tell me hw use rich edit box in win 32 application.

Use LoadLibrary for initializing rich edit control. You main window procedure would look like this,

LRESULT CALLBACK WndProc(HWND hwnd, UINT Message, WPARAM wParam, LPARAM lParam)
{
switch(Message)
{
case WM_CREATE:
hLib = LoadLibrary("RICHED32.DLL");
break;
case WM_CLOSE:
DestroyWindow(hwnd);
FreeLibrary(hLib);
break;
..

}

Hi Prasad, what shd be the hlib variable type ??? and where we have to declare that variable?? error C2065: 'hLib' : undeclared identifier

[prasad_som]

Its HMODULE. You can declare it as

HMODULE hLib;//of course you can decide how you want to manage it

I've just given example. Only thing important, you need to load dll before invoking dialog.

Hi Prasad, I did changes as u have mentioned. But still no changes , still the dialog is not getting displayed which contains rich edit box.If i remove the Rich edit control Dialog is getting displayed. I have 3 dialogs one main another sub dialogs , in the sub dialog I have the rich edit control. The main MainDlgProc BOOL CALLBACK MainDlgProc(HWND hwnd, UINT Message, WPARAM wParam, LPARAM lParam) { HMODULE hLib; switch(Message) { case WM_CREATE: hLib = LoadLibrary("RICHED32.DLL"); break; and the sub dialog DlgProc BOOL CALLBACK SearchDlgProc(HWND hwnd, UINT Message, WPARAM wParam, LPARAM lParam) { HMODULE hLib; switch(Message) { case WM_CREATE: hLib = LoadLibrary("RICHED32.DLL"); break; I am using windows 2000 OS with VC6.

Dear ! dear ! I mentioned in earlier reply, you need to load library before invoking dilaog. I'd assumed , you main application window is not dialog window in question, and window procedure I mentioned is of main window. So use given procedure with main window. You should get idea from this snippet,

hLib = LoadLibrary("RICHED32.DLL");
ret = DialogBox(GetModuleHandle(NULL),
MAKEINTRESOURCE(IDD_MYDLG), hwnd, MyDlgProc);
if(ret == -1)
{
MessageBox(hwnd, "Dialog failed!", "Error",
MB_OK | MB_ICONINFORMATION);
}
FreeLibrary(hLib );

If you want to use of functions on a dll you need first to load it dll and then use of functions
