Hello, this: CFileDialog dlg(FALSE); CString fname = dlg.GetPathName(); const char* szBuffer = fname; int i = sizeof(szBuffer); CFile f; if( f.Open ("F:\\test\\id.txt", CFile::modeWrite ) ){ try{ f.Write(szBuffer, i); f.Close(); } catch (CFileException *e){ AfxMessageBox ("Error!"); e->Delete(); } } } ...if you type in "rtf" it insert in my "id.txt" file: F:\r¼ÖA

You might want to try:CFileDialog dlg(FALSE); CString fname = dlg.GetPathName(); const char* szBuffer = fname.GetBuffer(0); int i = fname.GetLength(); CFile f; // CFile::modeWrite is OK if you want to append // data to the end of the file. If you're looking // to create a new file and have it contain JUST this // filename, you need to open the CFile with the // CFile::modeCreate flag. if( f.Open ("F:\\test\\id.txt", CFile::modeWrite ) ) { try{ f.Write(szBuffer, i); f.Close(); } catch (CFileException *e) { AfxMessageBox ("Error!"); e->Delete(); } } // And remember to release your string pointer. fname.ReleaseBuffer();

int i = strlen(szBuffer); rechi

It works!!!!Thanx. Thanks, Mark

By the way, how can i change the code to read the file? Thanks, Mark

Try:CFileDialog dlg(FALSE); CString fname = dlg.GetPathName(); char* szBuffer = NULL; int i = 0; CFile f; if( f.Open ("F:\\test\\id.txt", CFile::modeRead ) ) { try { // Get the size of the file. i = f.GetLength(); // Create buffer to hold file data. szBuffer = new char[i]; // Read in the file data if(szBuffer != NULL) f.Read(szBuffer, i); // Close the file. f.Close(); } catch (CFileException *e) { AfxMessageBox ("Error!"); e->Delete(); } // end TRY-CATCH } // end IF // If szBuffer != NULL, it contains the file data. // Do whatever you want to it, and then make sure you // clean up the dynamic memory you new'ed. if(szBuffer != NULL) delete [] szBuffer;

CFileDialog dlg(FALSE);

dlg.DoModal();

CString fname = dlg.GetPathName(); 
const char\* szBuffer = fname;
char s\[128\];

int i = lstrlen(szBuffer);

CFile f;
if (f.Open("F:\\\\test\\\\id.txt", CFile::modeWrite | CFile::modeCreate) == TRUE)
{
    try
    {
        f.Write(szBuffer, i);
    }
    catch (CFileException \*e)
    {
        AfxMessageBox ("Error writing!");
        e->Delete();
    }
        
    f.Close();
}

if (f.Open("F:\\\\test\\\\id.txt", CFile::modeRead) == TRUE)
{
    try
    {
        f.Read(s, i);
    }
    catch (CFileException \*e)
    {
        AfxMessageBox ("Error reading!");
        e->Delete();
    }
}

I must cast the szBuffer to a CString type: CString csPath = szBuffer; is this allowed? Thanks, Mark

[David Crow]

Actually, this implicitly casts szBuffer to a LPCTSTR, which CString has an assignment operator for.

Nice, but still generates test.pmjyyyxx as output???? Thanks, Mark
