I wish someone here could help you out, but I suggest you not to *magnify* your question. Remove all those bold style and post a neat question. An example:
Hi Friends,
I have a top level window. I need to show background magnified contents into the window. [Explain a bit more here]
My approach:
I created the desktop bitmap on application startup i.e. m_hbitmapScreenShot.
I created a WS_POPUP window; on each mouse move call i move the window by specified offset calling MoveWindow API and draw the new location contnets into it.
CDC* pDC = GetDC();
CRect rc;
GetClientRect(&ec);
::StretchBlt(pDC->;m_hDC, 0, 0, rc.Width(), rc.Height(), m_hMemDC, nDesX, nDesY, m_nGlassSize /m_nZoomLevel,
m_nGlassSize / m_nZoomLevel, SRCCOPY);
I have two issues
1) When I move the window the background window is not painted at once; so my window traces remains at old location for a while.
2) How to capture background window bitmap when my window is up; I dont need my window in screen shot.
Also, The Other magnified glass disappears as left mouse button is up.
But I need to show it always.
I am attaching screen shot "Magnify.JPG" for your reference.
"Magnify.JPG" location

First of all, I agree with VuNic, please don't "run into the room and start yelling 'Look at me, look at me'", using the bolds will just get people upset around here.
And for your problem, try using a Layered window[^] for your "magnifying glass". If you get the desktop DC and use StretchBlt to blit from it you should see that your layered window over the desktop is not in the capture. But note that this works for all layered windows so your screen capture will not show ANY layered windows, not just your own.

I don't know.Maybe it use other windowsXP's dll? I copy user32.dll from winxp to win2000 and it don't work too.

PrintWindow is not supported in Win2K.
It is not enough to simply copy some DLLs from XP to make this work in Win2K.
I'm sure the call goes down to the kernel and calls some routines there.
So you will have to implement this the hard way without the PrintWindow function.

I have a problem with EAXDirectSoundCreate method call. If I created a DLL which uses MFC, and in the DLL's InitInstance() to revoke EAXDirectSoundCreate. When application runs, and loads the DLL, then EAXDirectSoundCreate executed, application will hang up inside of that method. Need your help here how to fix the problem. Thanks.

How do we build a network using visual c++..The network is assumed as graph.
|
|
|
|

We usually build networks using cables, hubs, switches,... 
If the Lord God Almighty had consulted me before embarking upon the Creation, I would have recommended something simpler.

No, you must have asked her to search for VC++ in Orkut, FaceBook ,etc. That's what the OP is looking for.
He never answers anyone who replies to him. I've taken to calling him a retard, which is not fair to retards everywhere.-Christian Graus

I should admit, you're more advanced too: How do you know the OP is a lady?

Hi,
Has anyone come across a simple way of making an MFC toolbar button flash? I tried using pCmdUI->Enable() with an alternating enable/disable flag which looked great but of course the button is disabled half the time 
TIA
Tony

|
|
|
How about alternating checked/unchecked?

Hi,
Thanks for the suggestion. I tried it and it looked OK but still not quite what I wanted. For info, I did manage to get the look I was after but I dont know if its the "correct" way to do it. I created two versions of the toolbar bitmap each showing the two states I needed. I loaded them into two image lists in CMainFrame::OnCreate(). I then swapped the image list into the toolbar on a timer, like this...
CMainFrame::OnCreate(LPCREATESTRUCT lpCreateStruct)
{
...
m_il1.Create(IDR_MAINFRAME1, 32, 0,RGB(128,128,128));
m_il2.Create(IDR_MAINFRAME2, 32, 0,RGB(128,128,128));
...
}
CMainFrame::FlashToolbarButton()
{
static bool bSwap = true;
if(bSwap)
{
m_wndToolBar.GetToolBarCtrl().SetImageList(&m_il1);
bSwap = FALSE;
}
else
{
m_wndToolBar.GetToolBarCtrl().SetImageList(&m_il2);
bSwap = TRUE;
}
m_wndToolBar.Invalidate();
}
Probably very ugly - maybe someone else has a more elegant solution.

How about an owner drawn toolbar[^]?

The code below produces the following compiling error:
STS_OP_temp_test.cpp: In constructor 'STS_OP_temp_test<U>::STS_OP_temp_test()':
STS_OP_temp_test.cpp:66: error: expected primary-expression before 'int'
STS_OP_temp_test.cpp:66: error: expected `;' before 'int'
I take the error to mean that the compiler can't resolve "cwtm.templateMethod". Either it doesn't think "cwtm" is defined, or it doesn't think cwtm has a method called "templateMethod".
If you don't quite understand the class template stuff happening here, go to this site:
http://publib.boulder.ibm.com/infocenter/comphelp/v8v101/index.jsp?topic=/com.ibm.xlcpp8a.doc/language/ref/template_template_arguments.htm
But that site doesn't solve my problem.
Thanks for your help.
