By following any one of the hundreds of examples that exist out there for this problem.

Or you could just sub-class the static and give it new behaviours so that (a) it's underlined, (b) has a different cursor (c) has a different colour (d) changes colour once visited (e) performs the desired action upon WM_LBUTTONUP, so long as it was under the mouse when the WM_LBUTTONDOWN message came in.

Remember, google is your friend. (Also, I believe Chris has written an article & class for this)

I haven't gone through the code for the link that I provided you. but the article writer must have used ShellExecute or something like that to help the user navigate to a URL on which he/she clicks. You can replace this code with creation/showing of a dialog

Hi,

You can use CFile, like this you open the file..

char* pszFileName = "c:\\test\\myfile.dat";
CFile myFile;
CFileException fileException;

if ( !myFile.Open( pszFileName, CFile::modeCreate |   
          CFile::modeReadWrite, &fileException ) )

like this you can read and write..

char      szBuffer[256]; 
UINT      nActual = 0; 
CFile myFile;

myFile.Write( szBuffer, sizeof( szBuffer ) ); 
myFile.Seek( 0, CFile::begin );
nActual = myFile.Read( szBuffer, sizeof( szBuffer ) );

Like this you close the file..

myFile.Close();

The price of anything is the amount of life you exchange for it.

Thanks and Regards.

sorry, I didn't notice that aspect of the things Smile | :)

The problem in your code is that you're using CFile::modeCreate, but according to the documentation[^], this flag tells to truncate the file if already existing :

MSDN says:
CFile::modeCreate
Directs the constructor to create a new file. If the file exists already, it is truncated to 0 length

So, you have to add the flag CFile::modeNoTruncate to counter this undesired behavior.
The use of this flag however keeps the file pointer at the beginning of the file. So if you want to append things at the end, you must call once after CStdioFile::Open() the function CStdioFile::Seek(CFile::end).

Does the following work better ?

CStdioFile file;
<font color="blue">if</font> (file.Open(_T(<font color="blue">"\\log.txt"</font>), CFile::modeCreate | CFile::modeWrite | CFile::modeNoTruncate)) {
    <font color="green">//file.Seek(0, CFile::end);</font>
    file.SeekToEnd();
    file.WriteString(logfile);
    file.WriteString(_T(<font color="blue">"\n"</font>));
    file.Close();
}
