I was not aware of this.
For backwards compatibility...? I thought managed C++ was to do this...?
So there is a CWnd in VS.NET...?

VS.NET ships with new, updated version of MFC. CWnd is still there.
Managed C++ is something entirely else.

Do you have the same version of MDAC installed on both machines? You can download it from the microsoft web site. www.microsoft.com/data

Can Visual Studio .NET still use my old custom appwizards from 6.0? I can't find any way to incorporate my *.awx files into the new IDE.

Hi,
I have started a project(DLL) which was not using MFC. But I need to add some of my classes which are derieved from MFC to this project. So, I added stdafx.h with all MFC includes to this dll and included where ever necessary. But still I am getting compilation errors that the MFC classes are undefined.
Can some one help me?
Thanks in advance

In addition to adding the MFC header files, you will also need to link with the MFC DLLs either statically or dynamically.

Hi Nish,
Thanks for your reply.
But if you are referring to the project settings/general/MFC classes
then, I have already chosen 'Use MFC in a static Library' option.
Should'nt that be enough? I still get the compilation errors.
Thanks

Yes, that should do.
You are getting compile errors eh?
Can you show your stdafx.h please?
And I presume you have included it in all your cpp files.

Perhaps post the actual error you are receiving.
Compilation error...? I don't think that has anything to do with including the right libs/dll's. The compiler goes blitz when your code is funny...like your using a structure that doesn't exist.
You have all the right includes...?

Is there a standard way in MFC to track the state of Scroll Lock, Num Lock
and Caps Lock?

Hmmm... try the Win32 GetKeyboardState call?
|
|
|
|
|
But, what is the event on which I call it?

If the user presses the key while you have the keyboard focus, you will get a WM_KEYDOWN and a WM_KEYUP message for those three keys.
If you want to know the state of the keys to display in your status bar like a lot of program sdo, then just call GetKeyState in your handler that updates your user interface.

|

I have to update the state, even when I do not have keyboard focus. (like the status bar does)

Then you need to use a timer.

If you want to display the state info on the Status Bar you'd do this in your CMainFrame::OnUpdateStatusBar() or am I missing something here?

Hi,
I have 2 GDI drawing problems and I was hoping you guys could help me out.
1. I have several bitmaps (8x8, 16x16 and 32x32) that I use in PatBlt to set the background of my view to mimic zooming. Everything else is drawn on top. The 8x8 and 16x16 bitmaps tile the background perfectly. However, the 32x32 doesn't work at all! Instead the back of the view is completely corrupted (almost like returning FALSE from OnEraseBkGrnd and whizzing windows over it).
Anyone know if PatBlt has a limit on the size of the bitmap it can use or what the problem might be?
2. I implemented the double buffering ideas put about on this and other sites to draw to an offscreen buffer and then blit it back to remove flicker. However, when I resize the window or my view is redrawn, the flicker is as bad as normal.
According to the examples, I'm not missing anything, so what might have I done wrong?
Thanks for any help,
Simon

As long as you are using an OS newer than Windows 95 you can do brushes larger than 8x8.
As far as the flicker when you resize your window, it may help to make sure that you frame window that contains the view does not have the CS_HREDRAW or CS_VREDRAW styles set.

Are all your images same in color depth..?
I dunno if PatBlt will blit 265 color images or not, I don't see why it wouldn't BitBlt does. Maybe try all 16 colors images and see what happens.
Double buffering...flicker free drawing is a pain or is that paint...?
If you sit down and think about it you'll figure it out if you haven't already. If you don't fully understand everything thats going I would suggest using CMemDC found here on CP or maybe read the article FLicker free drawing By Keith Rule...???
I have used all the double buffering classes and implemented myself both MFC and SDK and I couldn't figure out why my screen still flickered when I overrode OnEraseBkgnd() and OnPaint/OnDraw. Seems you can't have both painting...Tell me is you figure it out.
Cheers!
