Searching for Carriage Returns, etc with CString

[One2b]

I am attempting to find a Carriage Return, a Line Feed, and/or Tabs in a CString. I am trying to use the CString::Find function, but am not sure what the correct parameter it takes. I thought \015, \102, \011, would be find however, it says that I have an illegal escapte sequence. Can anyone tell me how i get CString::Find to search for CR, LF, or Tabs? Thx

'\n' is new line
'\r' is Carriage return

 

[AMosmann]

as far as I know:
\n -CR
\t -TAB

... the signs you need for output

but I am not sure, try it

ya i already tried those....the prob is that it says they are illegal escape sequences. I am not sure how CString::Find looks for carriage returns etc.

 

[scienzia]

Try:
'\r' carriage return
'\n' line feed
'\t' tab

This should work
Ex.

CString a;

...

int pos= a.Find('\r',0);
[\code]

If you want to find just one of the characters (don't care which) use:

[code]
int pos = a.FindOneOf("\r\n\t");
[\code]

Hope this helps...

Hmm maybe my problem lies somewhere else...do u mind lookin at my code? I am tryin to remove all comments from this CString (i.e anywhere I see a ;.

CString CParamString::excludeComments(CString &s)
{
TRACE("Entering excludeComment(CString &s)\n"
int iSLength = s.GetLength();
int iSFindSemiColons = s.Find(";;"
int iSFindCR = (s.Right(iSFindSemiColons)).Find('\n'); //Find a Carriage Return to find end of line
int iSFindTab = (s.Right(iSFindSemiColons)).Find('\t'); //Find a Tab to find end of line
//TRACE("This is a Carriage Return: %d\n", );
TRACE("iSLength: %d\n", iSLength);
TRACE("iSFindSemiColons: %d\n", iSFindSemiColons);
TRACE("iSFindCR: %d\n", iSFindCR);
TRACE("iSFindTab: %d\n", iSFindTab);

if(-1 != iSFindSemiColons) //If enter here, comments have been found
{
cszTmp += s.Left((iSLength - iSFindSemiColons)); //Add everything before the comments (ie ; to the CString
if(-1 != iSFindCR) //If enter here the end of the line is a Carriage Return and use everything past it to search for next set of comments
{
excludeComments(s.Right(iSFindCR));
}
if(-1 != iSFindTab) //If enter here there was a tab, check everything past it for comments
{
excludeComments(s.Right(iSFindTab));
}
else //If enter here neither tab nor carriage return were at the end, so check
{
excludeComments(s);
}
}
return cszTmp += s; //Done searching for comments, return final answer (ie, a CString with no comments)
}

if your cstring is n characters long and you find CR at
position p I don't think you can say s.Right(p). Should be
s.Right(n-p). Using p maybe you can say s.Mid(p) but I'm
not familiar with these cstring-functions. I prefer using
char with pointers for parsing text.
Once again : check those right-functions !
hope this helps
