CString WriteString;
	WriteString.Format("%s.%d d",WriteString,NI);

At above WriteStringthe buffer too small warning is shown when executed any times because CStringtype is not enough to hold string of any size.

My goal is to get content ofWriteStringto write in to a file at end.

But it shows the warning when size of WriteStringreach to a limit. Is there any other way to write these strings to a file?or make the writeString be of unlimited size.

How much data is the WriteString holds. Actually there is no size limit for CString. Depends on system memory and process memory. Please post the exact warning message and line you are getting.

Solution 1

In the Format(..) context,
try to use the string as the receiver only Smile | :) :
CString cszComposed(_T("SomeValue"));
CString cszTemp;
cszTemp.Format(_T(".%d d"), NI);
cszComposed += cszTemp;

If your objective is to reuse variables, here goes the way to go:
CString WriteString;
WriteString.Format("%s.%d d", CString(WriteString),NI);</pre>

Notice the CString() constructor call. You will have not problems because your format receives a copy of WriteString, instead of manipulating it directly.

Do you really think the OP is still looking for a solution to a solved question from over three years ago?!

Posting new answers to old, solved questions is a form of abuse - you're not trying to help the OP, you're just trying to increase your reputation points.

Do you think I care that much about my reputation here? This is the first time I went to see it. Almost all points I got were from Sign Ins, that most likely are done automatically by the browser.
