however I had to do some operations like name.append(".txt" which don't seem to be working if I declare name as a CString variable.

WinExec("findstr /C:\"ERROR #1028\" C:\\SERVER.log > C:\\temp_log.txt", SW_HIDE)

But, the output seems to be not re-directing to the temp_log.txt file.
I even tried creating the file temp.txt before executing the same, but the contents will be blank. Even I tried the >> operator too.
