See Saving a Drawing to a Bitmap File[^] (Its with MFC but I think you can convert to Win32).

I am writing a mouse hook program to trace the mouse movement and something confused me. I use WH_MOUSE to hook the mouse event in global wide, but some message like WM_MOUSEMOVE can not hooked when the mouse leave the window with a left/right button down, so I have add the SetCapture() function to my code when the GetCapture() return NULL, but it does not worked well, in some window like "MS word" or "Winamp" it go wrong.

I have also tried the WH_MOUSE_LL, it realy worked well. but it slowness the animation In window XP when turn on the visual effect "animation the window when Maxminze or Minmize", you will find the mouse move slowness when you click the mini/max box in the titlebar in any window with the mouse move quickly.

It totally confused me, some one can help me.

Thanks.

First question, why do you want to hook the mouse?

Second question - What makes you think you can capture the mouse and no other app
is going to capture the mouse itself?

That's a naughty thing for a mouse hook to do Smile | :)

Slowing the system down with your
hook is generally considered BAD as well.

I want hook the mouse to trace the mouse move track, so I can measure the mouse move distance on the screen. And in the hook, my App just want to filter the cursor' position from the "lParam" parameter.The problem is I can filter the cursor's position in any window with mouse move in its window's rect, but if I press a left/right button down in the window then keep the button hold and move the mouse out of this window, the mouse message will skip this hook which using WH_MOUSE.

So I use the WH_MOUSE_LL hook, every thing goes fine here, only slow the mouse when I click the min/max box on the window's title bar with mouse move quickly, if you are using WinXP turn on the visual style "animation the window when Maxminze or Minmize" and download sn app.zip from this address: "http://www.codeproject.com/useritems/MBtn2DblClickVC.asp" which hooked with WH_MOUSE_LL too, it will appear this problem also.

Could you give me some advise to solve this problem, using WH_MOUSE but how to capture the out window message, or using WH_MOUSE_LL but avoid slow the mouse move?

thanks. Smile | :)

"Untitled" is not the name of your application. What you are referring to is the caption text. You did not indicate on which side of the '-' you wanted to change, so my suggestion is for the right side. The preferred method is to change IDR_MAINFRAME in the string resource table.

You set it with CDocument::SetTitle().

Normaly - loading a Document automagically changes the Document title to "DocumentName - ProjectName"

That is true.
I was under the impression that he was unhappy with the "Untitled-" part of what he thought was the name of his EXE.
But you are right - he might have wanted to change something different.

Which the OP was not wanting to do. He clearly wanted to alter the caption. He just failed to indicate which part.
