According to MSDN [^] this could also mean that your call was successful and "the return value is the number of scan lines copied from the bitmap". Perhaps you can post a code snippet?

To add to Moaks reply...
You're passing NULL for "LPVOID lpvBits" parameter, correct?
If so, have you initialized the struct pointed to by the "LPBITMAPINFO lpbi" parameter properly?

So does the Utility class provide such a method?

I have a window inherited from CView, used for showing pictures.
When moving dialog over it, there are sometimes black lines left on the window. It seems like calling InvalidateRect with a little small rectangle area as parameter. I don't know how it comes out. Please help me solve it!
I set this window's map mode to MM_ISOTROPIC and the logical extent is smaller than device extent.
Does it have something to do with the problem?
Thanks in advance!

Are the lines just on the pictures or in the entire view window?
Regardless, you are responsible for repainting any invalid areas of the window.
The MM_ISOTROPIC mode only comes into play when you are doing this painting...

Call the function again in OnDraw() function to draw whatever you are drawing in the view window.

and indeed sscanf does what you are requiring. see here [^].

Will CString::Format be helpful ?

actually i didn't try it but sscanf was just fine
Thanks for ur valuable time ur all great
thanks

you can do:
k = strtol(s, &pStop, 16);
where pStop is a char pointer (see strtol documentation).
of course you'll get k=0x1E.

First of all, I'm still using MFC4.2 with VC6. But the problems I ran into are probably the same since Win3.x .
I have a CDialog, made with the dialog editor. Beside other controls I have a tab control in this dialog, which is attached to a CTabCtrl Object.
Now I want to mask out a part of this tab control. Easy, isn't it?
So I created dynamically a CStatic object, "Static1", with the background color corresponding to the dialog background color and sized and positioned the window to cover the area that I want to mask out. This static is a child of the TabControl.
So far so good.
But as soon as the tab control is repaintd my static control disappeared behind the tab control.
I made a second static control, "Static2", this time with the resource editor. This static is not a child of the TabControl.
Same behaviour.
I tried to adjust the z-order of "Static1". No effect.
I even called SetWindowPos with the wndTopMost pointer after each button down-, selection change- and WM_PAINT notifictaion, just for the case that the z-order is changed somehow somewhere. No success.
The behaviour is:
Upon startup or completely repaint of the dialog I see "Static1" and "Static2" ("Static2" is above "Static1").
After changing the Tabs (or hovering) I see the tab control. (Static 1 & 2 are behind the tab control).
If the statics are just covered by a window and drawn again afterwards, the result is indetermined, mostly all three controls are only drawn partitially in the overlapping area.
What can I do to nail my static on top of the tab control and that it gets repainted AFTER every repaint of the tab control?
Regards
Leo
