With MFC you could lookup how to use class CStdioFile (see the Read() and GetLength() member functions).

thank u for ur fast reply
i tried the CFile class open and read
but it didnot work because it had something to do with my file...so can u help me with this ???bear with me pleease.
and how can i set the text to my edit control... i tried setwindowtext () but i had an error saying :
error C2039: 'SetWindowTextA' : is not a member of 'CString'
again ....thank u

Basically you can read a file like

CStdioFile File;
File.Open("c:\\file.txt", CFile::modeRead|CFile::typeBinary);
DWORD size = File.GetLength();
BYTE * p = new BYTE[1+size];
if(p)
{
    File.Read(p, size);  // Read should return the value of 'size'
    p[size] = 0;		
}

SetWindowText() is a member of CWnd, so if you have pointer (CWnd *) to your window, call it like

CString str = "Text";
pWnd->SetWindowText(str);
