Here's Irwin's code..

Code:

VOID FilterString(__in_z LPCTSTR lpcszFilterString, __in TCHAR tch, __out_z LPTSTR lpszBuffer)
{
TCHAR tchUpper = _totupper(tch);
UINT i = 0;

for (; i < _tcslen(lpcszFilterString); i++)
if (_totupper(lpcszFilterString[i]) != tchUpper)
lpszBuffer[i] = lpcszFilterString[i];
lpszBuffer[i] = _T('\0');
}

So I used..

Code:

FilterString(szScript, '\t', szScriptAll);

szScriptAll should have been "nn", but instead, it's..

Code:

n
n

I can't filter '\n' for some reason, but I can filter every other character. Help?

Code:

char* FilterCharacter( char* szSrc, const char* Filter ) {
char* szReturn = new char[500];
char* szToken = strtok( szSrc, Filter );
while( szToken != NULL ) {
strcat( szReturn, szToken );
szToken = strtok( NULL, Filter );
}
return szReturn;
}

I have no idea if it works, i coded it off the top of my head.

Irwin's posted code was wrong. Here's the fix that i applied:

Code:

VOID FilterCharacter(__in_z LPCTSTR lpcszFilterString, __in TCHAR tch, __out_z LPTSTR lpszBuffer)
{
TCHAR tchUpper = _totupper(tch);
UINT i = 0, pos = 0;

for (; i < _tcslen(lpcszFilterString); i++)
if (_totupper(lpcszFilterString[i]) != tchUpper)
lpszBuffer[pos++] = lpcszFilterString[i];
lpszBuffer[pos] = _T('\0');
}

FilterCharacter("t\testt\tes\tstt\test", '\t', buffer);

and

FilterCharacter("tes\nts\nttes\nt", '\n', buffer);

work perfectly fine.

Hmm, interesting.. in a multi-line text box, is a new line (hitting the return key) interpreted as a '\n'?

Probably.. convert the string to hex and check.

\n = 0x10 = Line Feed

It may be represented by \r\n instead, and that could be the problem.
