You could try the VC++ forums if you are a VC++ guy. This is the C# forum.

except codeguru.com,codeproject.com,tek-tips.com!
are there any more that is attracting more and more people??thanks!

This is an odd request. What you're looking for ( flexgrid ) is an odd request, you're unlikely to get an answer. However, codeguru & CP are IMO without doubt the most populated sites on the web. In any case, if you can't figure out www.google.com, you probably shouldn't be programming.

Well said Christian. Coming in here and asking about other forums is tantamount to going into a restaurant and asking the chef there to give you the names of his competitors.

*grin* That reminds me of the time I bought pizza from Pizza Hut and took it into McDonalds next door, and sat down to eat it ( some friends wanted the Golden Arches, I wanted something that resembled food ). I was asked to leave.

Man! That's harsh! I'd be like "Hey, my buddies are buying your food and besides you don't even sell pizza!!"  Of course, it would not have worked out any better for me. I just like to be argumentative

I was well known there - I'd tried to get served in the drive through on foot by getting friends to make car noises while I ordered and holding a plate as a steering wheel.....

I was at a McDonald's that sold pizza, I think it was somewhere in Kentucky; but that was 7 years ago.

I have been trying to optimise my screensaver, because when double buffering is turned on it slows right down. I create a bitmap and graphics object in memory, draw to that instead of the screen and in the paint method, draw the bitmap to the screen. There is too much action going on to try and draw only the changed bits. It's slower than turning on double buffering - how can this be ? What faster method for double buffering could exist ? I'm using graphics::drawimageunscaled, but I've tried drawimage.

I think my next project is going to be a class that manages dirty rectangles. 
But for a quickie, what happens if you only update the area that is needed in the OnPaint event (ie use the PaintEventArgs.ClipRectangle). I have a hunch that something is causing the Paint event to be fired outside of your Invalidate(false) so if you draw everything over again, a lot of that is wasted cycles because it will only get clipped off.

Invalidate(false)
Ok James, please fill me in on this, what does Invalidate(); do? I don't seem to find a *visible* method called Invalidate(); but I see people calling it.

Invalidate is a method that comes from the Control class, calling Invalidate() or Invalidate(bool) forces the control to repaint itself and optionally its child controls.
The other overloads forces a repaint of only a specific area of the control and optionally its child controls.
The term comes from the Win32 API where a window was Invalid if a part of it needed repainting, calling Invalidate set it so the whole window needed updating or just a specific part of it.

I don't see what else would fire my paint message, but my resolution is (2x1280)x1024, and the *whole* screen needs to be drawn every time. There is stuff going on everywhere. If I run 800x600 it runs very nicely.

Sorry, I did a search for DrawCachedBitmap using the Graphics class from the .NET Framework and didn't find it, maybe is not implemented for .NET
anybody knows why is not exposed through the .NET Graphics class ?
<MyOriginalMessage>
From MSDN Help:
CachedBitmap Class
A CachedBitmap object stores a bitmap in a format that is optimized for display on a particular device. To display a cached bitmap, call the Graphics::DrawCachedBitmap method.
Remarks
A CachedBitmap object stores an image in a format that is optimized for a particular display screen. You cannot draw a cached bitmap to a printer or to a metafile.
Cached bitmaps will not work with any transformations other than translation.
When you construct a CachedBitmap object, you must pass the address of a Graphics object to the constructor. If the screen associated with that Graphics object has its bit depth changed after the cached bitmap is constructed, then the DrawCachedBitmap method will fail, and you should reconstruct the cached bitmap. Alternatively, you can hook the display change notification message and reconstruct the cached bitmap at that time.
Example Code [C++]
The following example calls DrawCachedBitmap to draw the image stored in a CachedBitmap object.
VOID Example_DrawCachedBitmap(HDC hdc)
{
Graphics graphics(hdc);
// Create Bitmap object.
Bitmap bitmap(L"Climber.jpg");
// Use the Bitmap object to create a CachedBitmap object.
CachedBitmap cachedBitmap(&bitmap, &graphics);
// Draw the cached bitmap.
graphics.DrawCachedBitmap(&cachedBitmap, 20, 10);
}
I've used it on a project, and it speed the things up (actually i'm not using it right now, see below)
But it's not as flexible as DrawImage (at least in C++, haven't tried it with c# yet)

Your second buffer needs to be in frame buffer memory. Then switching between the two frames is VERY VERY fast. Of course, if you aren't using OpenGL or DirectX, I have no idea how to do that.
Tim Smith
I know what you're thinking punk, you're thinking did he spell check this document? Well, to tell you the truth I kinda forgot myself in all this excitement. But being this here's CodeProject, the most powerful forums in the world and would blow your head clean off, you've got to ask yourself one question, Do I feel lucky? Well do ya punk?

AFAIK only OGL and DX let you do that... Still waiting for DX 9 to come out for C# code support

Can anyone tell me how to change the screen resolution in C# ? How about for multiple monitors ?
