Are you wanting to send a message to the control that currently has focus?
Yes I want to send message to the editable control that currently has focus.

What do you mean by "common class name" and "general name?"
When I use FindWindowEx I have to pass name for the control as below
HWND hEdit = FindWindowEx(hHandle, NULL, "Edit", NULL);
This is for notepad so from here I want for all control

Use SendMessage().

Not possible. The best you could hope for would be to send the message to HWND_BROADCAST. But this will not work for child windows.

Simple toolbar inside a dockable toolbar

Hi,
here are many interesting articles and samples in the CODE PROJECT about DOCKING TOOLBARS and how to add text, list, buttons inside a dockable toolbar.
But how to add a simple toolbar inside a dockable toolbar and made it active?
Of course, no problems to create and see it in the dockable toolbar by using CreateEx() and LoadToolBar() methods - but how to enable the toolbar buttons?
Neither event ON_UPDATE_COMMAND_UI nor EnableButton() function do not help (if to add them into OnSize() function and do re-sizing of the dockable toolbar with mouse, time from time for a few millisecods the toolbar buttons are enabled, but they immediately return to disabled mode).

Ujjwal
U can do one thing set up a threshold limit
for every image say which represent the focused area.
Copy the image in the memory ,
Do this for every image and later on u can merge the
immage.
I have worked a bit on OpenGL but i dont know if there
are any special class developed for such functions.

thank you

You can use this code:
ShowWindow(SW_SHOWMAXIMIZED);

But of course it must be called inside the class of the window you want to maximize (otherwise, get a pointer to the target CWnd and call the ShowWindow from that window).

I have tired using the
ShowWindow(SW_SHOWMAXIMIZED);

I have created a child window then got the pointer
to the window & when i display the window by
the ShowWindow(SW_SHOWMAXIMIZED);
It should show me two the main window min_,max_,close_ button
& also the min_,max_,close_ button for the child window.

But the child window's min_,max_,close_ button disappear, and
i am not able to close the window

You'll need to figure out atleast the approximate place where the crash happens. IMO, log files are the best to figure that out.

You can also try attaching the application to Visual Studio, turning on "Break into the debugger on Win32 exceptions and C++ exceptions (Debug->Exceptions) and letting the application crash.

Assuming you're using VS .NET 2003, there's nothing special you need to do. Run your application, fire up Visual Studio, goto Debug->Processes, select your application and click Attach. You obviously won't be able to step through the code, but you can ask VS to break into the debugger if a Win32 exception or C++ exception happens.

Without being more specific, "table form" is too ambiguous. You could write the string data to a file and say it is a 1x1 table, or you could write it to a file and say it is a 1xN table where N is the number of 'words' in the string.

Hey, Sorry for late. just i came.
This is also one way.

CDialog dlg;//This can be any window
dlg.ModifyStyle(WS_MAXIMIZEBOX,0);//To remove the max btn.
dlg.ModifyStyle(0,WS_MAXIMIZEBOX);//To add the max btn

//Like this you can add any style and remove any style

This is simple way. At runtime you can change the style of any control or any window. see about modifystyle in msdn.

Nice talking to you. Blush | :O
