HWND handle

[enzo972002]

Hi folks!

I'm working on a MFC project and i've got a question to make. The project i'm involved in, is a dialog based aplication. So, the Wizard took the first steps of the work. I'm basing the program on an example that has been created entirely programming, and it makes reference to a HWND handle variable that is necessary to pass to one of the methods.

The code is like this:

 HRESULT CText::BlendText(HWND hwndApp, TCHAR *szNewText)
{
    
	LONG cx, cy;
                HRESULT hr;
	CSubtitlesDlg dialog;

	// Create a device context compatible with the current window
	HDC hdc= GetDC(hwndApp);
	HDC hdcBmp = CreateCompatibleDC(hdc);

	// Write with a known font by selecting it into our HDC
                HFONT hOldFont = (HFONT) SelectObject(hdcBmp, g_hFont);

	// Determine the length of the string, then determine the
                // dimensions (in pixels) of the character string using the
                // currently selected font.  These dimensions are used to create
                // a bitmap below.
                int nLength, nTextBmpWidth, nTextBmpHeight;
                SIZE sz={0};

	nLength = (int) _tcslen(szNewText);
	GetTextExtentPoint32(hdcBmp, szNewText, nLength, &sz);
	nTextBmpHeight = sz.cy;
                nTextBmpWidth  = sz.cx;

                // Create a new bitmap that is compatible with the current 
                //window
                HBITMAP hbm = CreateCompatibleBitmap(hdc, nTextBmpWidth,   
                nTextBmpHeight);
                ReleaseDC(hwndApp, hdc);

	// Select our bitmap into the device context and save the old one
                BITMAP bm;
	HBITMAP hbmOld;
	GetObject(hbm, sizeof(bm), &bm);
	hbmOld = (HBITMAP)SelectObject(hdcBmp, hbm);
 ...

I make a reference to this method in another class like this:

 hr = Text.BlendText(___________, Text.g_szAppText);

<- I need to know what to put in here

Does anybody know which method do i need to use in order to get this handle to the window i'm working with? I wonder if the question is clear, but i'll try!! Many thanks. Serj.

The handle of the window. If you have a CWnd object you can use GetSafeHwnd() to get its handle.

This is the only CWnd i have in all the project:

CSubtitlesDlg::CSubtitlesDlg(CWnd* pParent /*=NULL*/)
: CDialog(CSubtitlesDlg::IDD, pParent)
{

If the function that calls Text.BlendText is a member of your CSubtitlesDlg class, then you can just place GetSafeHwnd(). But the window must exist at the time of the call to get a valid HWND.
