You need to increase non client area size for this purpose handle WM_NCCALCSIZE, add a message map entry for ON_WM_NCCALCSIZE()...
A sample implementation looks likewise...
void CDialogTestDlg::OnNcCalcSize(BOOL bCalcValidRects, NCCALCSIZE_PARAMS* lpncsp)
{
UNREFERENCED_PARAMETER( bCalcValidRects );
lpncsp->rgrc->top += 4;
lpncsp->rgrc->left += 4;
lpncsp->rgrc->bottom -= 4;
lpncsp->rgrc->right -= 4;
CWnd::OnNcCalcSize( bCalcValidRects, lpncsp );
}
Also note that you may need to handle WM_NCPAINT to fill out increased region.

Hai !
GoodMorning !
I am able to read the contents of a whole xyz.txt file into an character array, using
CFile cfile_object;
cfile_object.Open( strFilePath, CFile::modeRead);
// strFilePath contains the path of the required file
int len = cfile_object.GetLength();
char chFile[len];
UINT lBytesRead = cfile_object.Read (chFile, len);
chFile contains whole content of xyz.txt file, but i want each line of xyz.txt file to be stored in a separate string?
if possible plz supply some sample/reference code.
thanks!

CStdioFile::ReadString - Reads a single line of text.
Somethings seem HARD to do, until we know how to do them.

Hi,
I have a function which is accepting two parameters LPARAM and WPARAM. The value being passed to this function by the URL is very big which cannot be stored in LAPARAM. Which data other than LPARAM should i take so that there is no loss of information.
Thanks.

One option is to allocate a block of memory and have the receiving function delete. I've also used a common circular buffer.
Anyone who thinks he has a better idea of what's good for people than people do is a swine.

Hi,
It not only recieves the data but also has other functions. Is there sny other way. Please tell me how you have used circular buffer.
Thanks

Rather than do that, try the simplest way first. The sending function allocated memory with new, the receiving function deallocates it with delete.
The other methods are a bit too verbose to explain here. Choosing which one will depend on how the message is sent, synchronously, asynchronously, from one source, from multiple sources and so on.

Send WM_COMMAND to dialog with WPARAM as IDCANCEL.
::SendMessage( hWnd, WM_COMMAND, IDCANCEL, 0 );
