I was developing a small project, during development i need to view the list of all opened windows in my explorer. i read somewhere and like to post the solution of this only for you :-)

It is very simple. here is the example by which you can display titles of each window opened. try this and enjoy.
In your OnInitDialog() write this…

HWND hnd = ::GetWindow(::GetDesktopWindow(), GW_CHILD);
CWnd *pWnd;
CString csTitle = "";

while( (hnd != NULL) )
{
pWnd = CWnd::FromHandle(hnd);
pWnd->GetWindowText(csTitle);

MessageBox(csTitle, "Title", NULL);
hnd = *pWnd->GetNextWindow(GW_HWNDNEXT);
}

I put some time to draw a border around a Dialog in MFC application. Here is the solution that i found. It is very simple for any level of programmer.

Follow just three simple steps.

Step1:

Add OnCtlColor() method in your Message map like:-

BEGIN_MESSAGE_MAP(CDATToSWFDlg, CTrayDialog)
ON_WM_CTLCOLOR()
END_MESSAGE_MAP()

Step2:

Add this method in your code.

HBRUSH CDATToSWFDlg::OnCtlColor(CDC* pDC, CWnd* pWnd, UINT nCtlColor)
{

CBrush m_brush;

m_brush.CreateSolidBrush(RGB(239, 255, 255)); // Set color to your Dialog
///////// SETTING BORDER /////////

pDC = GetWindowDC();
CRect rect;
GetWindowRect(&rect);
rect.OffsetRect( -rect.left, -rect.top);
CBrush brush( RGB(0, 0, 0)); // Color of your desired border
pDC->FrameRect( &rect, &brush);
int borderWidth = 4; // Set the width of your desired border.
for(int i=1; i<borderWidth; i++)
{
rect.OffsetRect( -rect.left+i, -rect.top+i);
pDC->FrameRect( &rect, &brush);
}
HDC hdc = pDC->GetSafeHdc();
for(i=1; i<borderWidth; i++)
{
rect.OffsetRect( -rect.left-i, -rect.top-i);
pDC->FrameRect( &rect, &brush);
}
ReleaseDC(pDC);
//////////////////////////////////
return m_brush;
}

Step3:

Define OnCtlColor() method in header file of Dialog like:-

class CDATToSWFDlg: public CDialog
{
// Construction
public:
HBRUSH OnCtlColor(CDC* pDC, CWnd* pWnd, UINT nCtlColor);
}

Thats it…. Now just run it and enjoy :-)
But please add in comments if you have any powerful solution.
Thanks.

If you want to change the background color of your dialog box, it is a very simple.

In your CTestDlg header file, declare a member variable from CBrush:

class CTestDlg : public CDialog{…protected: CBrush m_brush;…};

Then, add this line in the OnInitDialog function:

BOOL CTestDlg::OnInitDialog(){ … m_brush.CreateSolidBrush(RGB(255, 255, 255));

// color white brush …

}

Finally do this on the ID_CTLCOLOR handle:

BEGIN_MESSAGE_MAP(CDesktopToSWFDlg, CTrayDialog) ON_WM_CTLCOLOR()END_MESSAGE_MAP()

HBRUSH CAboutDlg::OnCtlColor(CDC* pDC, CWnd* pWnd, UINT nCtlColor){

/*** No need to do this!****

HBRUSH hbr = CDialog::OnCtlColor(pDC, pWnd, nCtlColor);

*//*** Return the white brush.*/

return m_brush;}

Hope it could help any fellow programmer.

Write this Function in your class.

HBRUSH CCaptureOPtionsDlg::OnCtlColor(CDC* pDC, CWnd* pWnd, UINT nCtlColor)
{
if( nCtlColor == 6 ) // for Slider control
{
pDC->SetBkMode(TRANSPARENT);// Set the Background Mode to TRANSPARENT }

else if( nCtlColor == CTLCOLOR_DLG ) // for dialog
{
pDC->SetTextColor(RGB(0, 0, 0)); // set the Text Color; black
pDC->SetBkMode(TRANSPARENT); // Set the Background Mode to TRANSPARENT
m_brush.CreateSolidBrush(RGB(214, 211, 206)); // Set RGB color any you want for your Dialog
}
return m_brush;
}
