please guide to do that.

Code is here

foreach (Microsoft.Office.Interop.Outlook.MAPIFolder folder in start)
{
                  node = node.Nodes.Add(folder.Name);

                   Microsoft.Office.Interop.Outlook.MAPIFolder found = TraverseTee(folder.Folders, name, bBuildTree, node);

                   node = node.Parent;

}

CFileFind can be called recursively to do the same

I want to capture the desktop as an image just like printscreen function. Any Win32 API or MFC class that perform the task.

THANKS.

Various methods for capturing the screen[^]

I believe there is a better way to do the Capture it the GDI way in the article.
Instead of GetDesktopWindow() and GetDC() you can use CreateDC(_T("DISPLAY"), NULL, NULL, NULL);

I love work. It gives me something to do between weekends.

Adam Roderick J29-Jul-09 20:23

29-Jul-09 20:23

offcourse superman's suggested method is better

see the code below for help Smile | :)

HDC hDesktopDC, hMemDC;
int nXPos = 0, nYPos = 0;
int nWidth = 0, nHeight = 0;
HGDIOBJ hOldBitmap, hBitmap;

// check for an empty rectangle
if ( IsRectEmpty( lpRect_i ))
{
return NULL;
}

// create a DC for the screen and create
// a memory DC compatible to screen DC
hDesktopDC = CreateDC( _T( "DISPLAY" ), NULL, NULL, NULL );
hMemDC = CreateCompatibleDC( hDesktopDC ); // get points of rectangle to grab
nXPos = lpRect_i->left;
nYPos = lpRect_i->top;
nWidth = lpRect_i->right - lpRect_i->left;
nHeight = lpRect_i->bottom - lpRect_i->top ;

// create a bitmap compatible with the screen DC
hBitmap = CreateCompatibleBitmap( hDesktopDC, nWidth, nHeight );
// select new bitmap into memory DC
hOldBitmap = SelectObject ( hMemDC, hBitmap );
// bitblt screen DC to memory DC
BitBlt( hMemDC, 0, 0, nWidth, nHeight, hDesktopDC, nXPos, nYPos, SRCCOPY );
// select old bitmap back into memory DC and get handle to
// bitmap of the screen
hBitmap = SelectObject( hMemDC, hOldBitmap );
// clean up
DeleteDC( hDesktopDC );
DeleteDC( hMemDC );
// return handle to the bitmap
return ( HBITMAP )hBitmap;

Thanks all of you for guidance and providing me a couple of alternates to perform the task. I would implement the stuff then I would be back , if i face some problem.....

Sorry, I have to ask very primitive questions but I did some work in VC++ around 9 years back and now forget every thing. Even I have to struggle to play with AfxMessageBox these days Smile | :)

Anyhow, now I want to display the captured image. The image is captured in HBITMAP hCaptureBitmap, so what class I should use to display the image. Suppose I have SDI based application and in View class what should I do......

Adam Roderick J29-Jul-09 23:35

29-Jul-09 23:35

no more direct code

Clue :-

1. device context.
2. SelectObject
3. bitBlt

Now try yourself Smile | :)

You mean , I should get the DC in view class by calling some thing like GetDC , then Select that DC and at the end by using bitBlt should display in the view class....

hmmm. what about if I take an object of Picturebox and then assign the handler of Bitmap to it. but I guess u are right there is no need to take an object of PictureBox, rather view class can be work as a placeholder as well. let me try

void CSDITESTView::OnFileTest()
{
int nScreenWidth = GetSystemMetrics(SM_CXSCREEN);
int nScreenHeight = GetSystemMetrics(SM_CYSCREEN);

HWND hDesktopWnd = GetDesktopWindow()->m_hWnd;

HDC hDesktopDC = ::GetDC(hDesktopWnd);
HDC hCaptureDC = CreateCompatibleDC(hDesktopDC);
HBITMAP hCaptureBitmap =CreateCompatibleBitmap(hDesktopDC,nScreenWidth, nScreenHeight);
SelectObject(hCaptureDC,hCaptureBitmap);
BitBlt(hCaptureDC,0,0,nScreenWidth,nScreenHeight, hDesktopDC,0,0,SRCCOPY|CAPTUREBLT);
::ReleaseDC(hDesktopWnd,hDesktopDC);
DeleteDC(hCaptureDC);

}

I guess this code should work as it is doing the all stuff already, but it not displaying anything ? why

Who will call the paint?

clue
1. Some one should call painting, isnt Smile | :)

Just simple, usually it is not done to give the whole code,
well check the below code.

HBITMAP CopyScreen( LPRECT lpRect_i )
{
HDC hDesktopDC, hMemDC;
int nXPos = 0, nYPos = 0;
int nWidth = 0, nHeight = 0;
HGDIOBJ hOldBitmap, hBitmap;

// check for an empty rectangle
if ( IsRectEmpty( lpRect_i ))
{
return NULL;
}

// create a DC for the screen and create
// a memory DC compatible to screen DC
hDesktopDC = CreateDC( _T( "DISPLAY" ), NULL, NULL, NULL );
hMemDC = CreateCompatibleDC( hDesktopDC ); // get points of rectangle to grab
nXPos = lpRect_i->left;
nYPos = lpRect_i->top;
nWidth = lpRect_i->right - lpRect_i->left;
nHeight = lpRect_i->bottom - lpRect_i->top ;

// create a bitmap compatible with the screen DC
hBitmap = CreateCompatibleBitmap( hDesktopDC, nWidth, nHeight );
// select new bitmap into memory DC
hOldBitmap = SelectObject ( hMemDC, hBitmap );
// bitblt screen DC to memory DC
BitBlt( hMemDC, 0, 0, nWidth, nHeight, hDesktopDC, nXPos, nYPos, SRCCOPY );
// select old bitmap back into memory DC and get handle to
// bitmap of the screen
hBitmap = SelectObject( hMemDC, hOldBitmap );
// clean up
DeleteDC( hDesktopDC );
DeleteDC( hMemDC );
// return handle to the bitmap
return ( HBITMAP )hBitmap;
}

void CSlideshawDlg::OnFirst()
{
RECT rect;
rect.left = 150;
rect.bottom = 500;
rect.top = 150;
rect.right = 500;
HBITMAP hBit = CopyScreen( &rect );
CDC memdc1;
CClientDC dc(this);
memdc1.CreateCompatibleDC(&dc);
memdc1.SelectObject( hBit );
dc.BitBlt(150,150,500,500,&memdc1,0,0,SRCCOPY);
}
