where are you opening the file for writing?
CFile file;
file.Open("c:\\abc.txt",CFile::modeCreate | CFile::modeReadWrite );
CString str;
str.Format ("%d",m_combobox.GetCurSel());
file.Write(str,strlen(str));
file.Close();
// This code is not optimized
// Now read the value similarly and use m_combobox.SetCurSel() to set the text in the combo box related to the index

you can use INI file for storing these type of configuration! http://www.codeproject.com/cpp/CIni.asp[^]

i canot understand how to use MapWindowPoints.so please tell how to use this with a\small example.
thank u,
sree.
|
|
|
|
|
If hwnd1 or hwnd2(or both) are mirrored windows (that is, have WS_EX_LAYOUTRTL extended style), MapWindowPoints will automatically adjust mirrored coordinates if you pass two or less points in lpPoints.
RECT rect[10];
for(int i =0; i < (sizeof(rect)/sizeof(rect[0])); i++)
{
MapWindowPoints(hWnd1, hWnd2, (LPPOINT)(&rect[i]), (sizeof(RECT)/sizeof(POINT)) );
}
//where hwnd1,hwnd2 are handle to the mirrored windows

Right from the DOCS:
CRect(
int l,
int t,
int r,
int b
) throw( );
CRect(
const RECT& srcRect
) throw( );
CRect(
LPCRECT lpSrcRect
) throw( );
CRect(
POINT point,
SIZE size
) throw( );
CRect(
POINT topLeft,
POINT bottomRight
) throw( );
You can use what suits you.

You can change your Rect dynamically using SetRect as following
CRect rect;
rect.SetRect(0,0, 420, 560);

-Set the range of the Slider as 0-255
-Invalidate the rect in Slider position change notification
-create the brush using the slider pos in OnPaint message and fill the Client area Rect of the Dialog.

A_Laxmancreate the brush using the slider pos in OnPaint message and fill the Client area Rect of the Dialog.
I tried that way but the screen flickers a lot and also i don't want to call OnPaint , so i would prefer some other alternative like WM_CTLCOLOR or WM_ERASEBKGND.I want some sample code.

HBRUSH CtestMFCDlg::OnCtlColor(CDC* pDC, CWnd* pWnd, UINT nCtlColor)<br />
{<br />
HBRUSH hbr = CDialog::OnCtlColor(pDC, pWnd, nCtlColor);<br />
return CreateSolidBrush(RGB(0,0,0));
}
Try the above code you will get the idea what to do next
