hi
i have a Device context. is there any way to findout if it change ?? (for example i foundout if a line drawn in it or any changes occures in it)
i want to Redraw a DC if it change. but first i have to findout if it change. 
thnx

It seems you don't really understand what a DC is. You can't draw lines in a DC, you can draw lines on a bitmap using a DC.
The DC is (among other things) more of a descriptor and abstraction layer of the target device and area.
If you however are sure no one else is selecting a new bitmap into the DC, you could possibly create two DIB sections, select one into the DC, select the other into a compatible DC, and blit the original bitmap into the second one. When you then want to check if anything has changed you can just memcmp the two memory areas.
It would probably be quite slow (I'd expect something like >5 milliseconds for just 640x480x24, even on a moderately fast machine), but short of alternatives it would at least work (maybe you'll have to use 32-bpp to not be bitten by DWORD-alignment and unspecified values at end of every line).

If you are using Memory Device contexts (where you select your own bitmap into the DC) then you can use this function to find the bounding box to the last changes since you ask for the changes:
::GetBoundsRect
However, if you are trying to detect changes on a window, then you will have to resort to other methods.

To ask the right question you have to know part of the answer. Try to read books, it helps.

It is like , when person loves "C#, ASP.NET and C++", but advises others to use gmtime instead of standard windows APIs.

And why didn't you mention that to him then, stupid "Anonymous"?
Do you know why forums are made? They are made to help people who asking for help.
You didn't help!
But I did... I can acknowledge that I forgot the Win32 API (GetSystemTime) because I've been to long inside the C Runtime Library now. But you knew about the Win32 API so, Why didn't you mention that? Doooooooooohh!!
BTW: Why are you anonymous? Don't you take responsibility for what you say?
Help or be quiet!

Would you like my home address too? I did not mention anything because with your irresponsible answers you are breading ignorant programmers. This person obviously does not know anything about Windows or programming in general. By giving him this "quick fix" you produced yet another hacker, rest of us have to clean up after. This guy should read something, anything, before even coming here.

Not necessary.

Hm... I answered him with "Look up time(...) and gmtime(...) in MSDN Library....". That is an answer for what he were asking for! And the first one, that thing with HWND and ID I didn't understood so I asked what he meant with that. What did You answered him? Nothing! You said he had to know some damn part of the answer!!
Do I bread ignorant programmers??? You're so stupid!

Right, then I told him to look up some functions that might be what he were looking for.
Better he look up things and read about it then I give him already written code!

Hacker? ROTFLMAO! 
We are talking about a way to get the minutes from time and how to get a HWND from some ID!

hi,
:-DI did not get convincing answer the last time.sorry if considered spam.
I am drawing these engineering related drawings that need a lot of pre calculation for neat display before actually being rendered to the user.Every time.Zooming included.I (naturally) used CreateCompatibleDC() function,drew onto that, calculated stuff and continued from there.
The problem arises while scrolling.I set the scrolling sizes according to the bounds of the drawing plus spaces.The bound is calculated as said earlier.When i scroll, things get eaten away.However, moving the drawing slowly using the arrow keys works fine.
Why is this happening?Help.Drawing is the soul and life and ... of my sw

I'm doing a MFC MDI app, with CScrollView view.
I am getting a very strange problem, the last row of the view is not visible until I resize the window in any way. I can scroll to the bottom, but it won't be visible until the window is resized(Even smaller, I can scroll there and it'll be drawn then)
This is how I set the scroll size
SetScrollSizes(MM_TEXT, CSize(1026, 1026),
CSize(64, 64),
CSize(1, 1));
Everything else draws fine though
This is how the last row is drawn
if (dc->RectVisible(CRect(CPoint(0, 1025), CSize(1026, 1))))
dc->FillSolidRect(0, 1025, 1026, 1, RGB(70, 70, 70));
Still happens if I do it without the RectVisible()

I can not get the above message to work in an ordinart CDialog messages map.
where the memberFxn looks like:
void edit1Return(NMHDR * pNotifyStruct, LRESULT * result )
{
MessageBox("Carrage return occured");
}
Must there be some kind of initializing in the program? Or how will I get the message to work?

The dialog is intercepting the pressing of the enter key (and calling OnOK) before it gets to the focused control. You can try disabling the translation of enter hits as follows:
BOOL CYourDlg::PreTranslateMessage(MSG* pMsg)
{
if(pMsg->message==WM_KEYDOWN&&pMsg->wParam==VK_RETURN)return 0;
return CDialog::PreTranslateMessage(pMsg);
}but we warned that playing with PreTranslateMessage can lead to all sorts of strange behaviors with your app.

Does anybody know how to change the mouse cursor form ? I've been trying using lhCursor = AfxGetApp()->LoadStandardCursor(....) to change the cursor image, then SetCursor(lhCursor) make the change visible and finally OnSetCursor to stick with the changes whenever the mouve moves. The problem is that when the mouse leaves the window and comes backin again, it resets it's cursor to the old image, not the one I changed it to.
Thank you

Load the cursor once in OnInitDialog and set it every time OnSetCursor is called just like this:
BOOL CYourDlg::OnSetCursor(CWnd* pWnd, UINT nHitTest, UINT message)
{
SetCursor(lhCursor);
return TRUE;
}I've tried it and it works OK.
