You need to add the entries of the control in the message map manually. The best way to do it is to look how class wizard does and do the same for your control.
So, add an edit box to your dialog, add the handler with classwizard look at the message maps entries (in the dialog class header file and source file) and see what has changed. Now you can do the same for your control.

Hi Cedric Moonen,
My Doubt is that the CEditBox doesn't Handle the WM_RBUTTON_DOWN Event. The Events handled for the Edit Box are.
EN_CHANGE,EN_ERRORSPACE,EN_HSCROLL,EN_KILLFOCUS,EN_MAXTEXT,EN_SETFOCUS,EN_UPDATE.
What about the Event Handler of WM_RBUTTON_WOWN Event.
please tell me your suggestions.

These aren't events handled by the edit control. These are notifications posted by the edit control to it's parent. In that case you can use WM_PARENTNOTIFY[^]. Or if your only interested in a right-click there is NM_RCLICK[^] notifications.

i made an application which used a dll and loads it dynamically. If dll is not present an exception raises. All i want is if dll is not present it should be known at the Loadlibrary(..) call and i could handle that exception.
Is my question meaningfull? If yes please help me.
Thank you

Hi all,
I have created a device independent driver. For which i want a application launcher. My drivers name is "TestIOCTL" and its symbollic link is "\Device\TestIOCTL ". I now want to open this driver file for which i have used the following code segment.
hDevice = CreateFile ("\\DosDevices\\TestIOCTL",
0,
FILE_SHARE_READ | FILE_SHARE_WRITE,
NULL,
OPEN_EXISTING,
FILE_ATTRIBUTE_NORMAL,
NULL
);
The hDevice returns 3 thro GetError() Method meaning File not found. Can anyone tell me how to open this driver file.
Thanks In advance.
Regards
Kenny.

Correction:
Error 3 means ERROR_PATH_NOT_FOUND
(Error 2 means ERROR_FILE_NOT_FOUND)
Just a hint, I never opened a driver myself.
But I suggest you try these for the "file" name:
L"\\\\.\\Device\\TestIOCTL"
L"\\\\.\\TestIOCTL"
L"\\\\.\\DosDevices\\TestIOCTL

I see two solutions:
1. Make an ownerdrawn control derived from the CListCtrl.
2. Use a grid control
~RaGE();
I think words like 'destiny' are a way of trying to find order where none exists. - Christian Graus

Another solution would be to use customdraw.

Probably, you written this code in OnPaint or similar function. Invoking message box cause it to call again(WM_PAINT)(it invalidates that area), and its going in endless loop.
Avoid calling messagebox there.

|

Yes, Im doing this in OnDraw().Ok Thank u.

More in general, avoid user interactions and whatever action that may be destructive respect to the drawing ... while drawing.
The good practice is to handle all user "options" with commands altering the "state" of the application (some member variables), and make OnDraw / OnPaint to already know everiting about their drawing.

hi,
Inorder to not write the Code in OnPaint(...) function which is repetative you can Write your own member Function.
in order to get the Device Context like on Paint(...) member function,
Use CDC* ptr = ::GetDC(...) // In your Member function,
OnPaint(...) is Repetative.
this will propably solve the Problem.
Good Luck.
