You should be aware of the XCHG assembler instruction which will exchange two values, uses 3 cpu clocks. Your optimizations will, in some cases, use 3x more CPU clocks, larger binary and unreadable code.

Splitter will just clone your picture to two monitors, why would you want that? SLI if you have nvidia gpu, which you dont... :) with ati it's called crossfire.

I did it, it works now, thank you.

OK thanks, this looks like something i needed.

I tried that already, look at this picture http://img214.imageshack.us/img214/6206/drawingfx6.png It draws button but without XP styles...

CImageButton class is very lousy way of replacing API function DrawFrameControl and i definitely don't need that... All that code is easily replaced with these 4 lines of code: CPaintDC dc(this); CRect rc; GetClientRect(&rc); dc.DrawFrameControl(&rc, DFC_BUTTON, DFCS_BUTTONPUSH); http://img214.imageshack.us/img214/6206/drawingfx6.png

Can you explain how do you think that i should use CBitmapButton class? As i see that class only helps in inserting bitmaps on to buttons, but it still needs me to draw the button (because my bitmap is displayed only on one small portion of button).

I will try.

OK thank you all for your answers, i will try it out and let you know if it's woking. In case my english is so bad that nobody understood what i want to do :), I want to draw something like this http://img252.imageshack.us/img252/2254/codeprojectkc1.png

I already tried something with WM_PAINT, but it didn't work. And after reading this article in MSDN i give up on WM_PAINT... "Handling WM_PAINT The most extreme choice is to implement a WM_PAINT handler and do all the painting yourself." http://msdn2.microsoft.com/en-us/library/ms364048(vs.80).aspx

It stops on some ASSERT... I know that i have to draw the entire button by myself, but my question is how do i let windows draw that button for me (with al it's visual styles) and i just want to draw small bitmap in right corner of button?

I want to draw a small arrow bitmap on top of already drawn button. I tried with calling default drawing proc before my code for drawing bitmap but it gives me some error. OnDrawItem(int nIDCtl, LPDRAWITEMSTRUCT lpDrawItemStruct) { CDialog::OnDrawItem(nIDCtl, lpDrawItemStruct); HDC thdc = CreateCompatibleDC(lpDrawItemStruct->hDC); HGDIOBJ tobj = SelectObject(thdc, LoadBitmap(AfxGetInstanceHandle(), MAKEINTRESOURCE(IDB_ARROW_DOWN))); TransparentBlt(lpDrawItemStruct->hDC, lpDrawItemStruct->rcItem.right - 20, lpDrawItemStruct->rcItem.top + (lpDrawItemStruct->rcItem.bottom - lpDrawItemStruct->rcItem.top - 16) / 2, 16, 16, thdc, 0, 0, 16, 16, RGB(255, 0, 255)); SelectObject(thdc, tobj); DeleteDC(thdc); } if i exclude "CDialog::OnDrawItem(nIDCtl, lpDrawItemStruct);" then code works, but there is no borders and caption text, just my bitmap.
