Try out the below code piece...

CDC* pDC = GetDC();

CDC memDC;
memDC.CreateCompatibleDC(pDC);

CBitmap bitmap;
bitmap.CreateCompatibleBitmap(pDC, 100, 100);

CBitmap* pOldBitmap = memDC.SelectObject((CBitmap*)&bitmap);

//
// Write the Text using memDC
//

pDC->BitBlt(0, 0, 100, 100, &memDC, 0, 0, SRCCOPY);

memDC.SelectObject((CBitmap*)pOldBitmap);

ReleaseDC(pDC);

Its pretty easy..Follow the above programming structure and replace the MFC functions with the equivalent Win32 APIs.This will be a good excercise to learn about the win32 multimedia/graphic APIs !.

p.s : I know it is little time consuming Poke tongue | ;-P

Rane's code makes a bitmap the same format as the
display. If you want to guarantee 24bpp or 32bpp
you can use CreateDIBSection() instead of CreateCompatibleBitmap().

Create a class for the edit control, in that class, handle the WM_CHAR message. When ever user press a character, that function will get called. The character will appear in the edit box only if you call CEdit::OnChar from that function. So if you want to prevent the characters, just dont call the base class function.

Handle EN_CHANGE notification. Find the '.' from the right side of the string. If found at 4th position from the last you should display the previously correct string and keep on displaying it else you can allow the user to enter the character.Also you would need to validate the values for some other entries like 13.1.1.0. Hope this helps you.

I don't have an example with me Big Grin | :-D

Why not simply use a masked edit control? Most of them supoport a mask that would look something like ##.##.

What confusion do you have in this? Confused | :confused:

This API sets the default Kernel or User Mode locale. If the first Parameter is set then this API sets the UserMode locale else KernelMode locale.The Second parameter corresponds to the type of Locale to be set.

For the list of locale codes, see here[^]

The APIs in ntdll (the ones that start with Nt) are usually not documented, on purpose. Unless you have an overriding need to use such an API, you should use a Win32 API instead.

Hi all,

How could I come to know that any popup is blocked in Internet explorer programmatically in my toolbar plug-in?

Actually I want to catch that event & need to do some operation over there.

Please help me.

Thanks for reply..

Actually I want to count the number of popups blocked by internet explorer & show that count to user as a caption of toolbar button.

As number of popups blocked increases my button caption also changes.

I want to make it something like Google Toolbar Popup Blocker.

Re: Help needed for Pop-up issue

You can achieve it using "cookies", which can hold information on the number of popup windows blocked.

I think Threads in MFC Part I: Worker Threads[^] is helpful for you.

Use Ctrl+Left/Right to switch messages, Ctrl+Up/Down to switch threads, Ctrl+Shift+Left/Right to switch pages.
