Hey, do you know if there is any Win32 API for extracting various parts from a string containing the file name with the whole path, or do I have to figure out some algorithm myself?
Or, if you have a code snippet at hand to do this work, could you paste it?
Thanks.
Depending on how your path is stored there may be various things you can try. If it is a simple c-style character array, the strrchr function can be used to find the last '\\' character in the array. If you have a string container storing the whole path/filename, then the rfind member function can be used in the same way. Once you have that position, the filename is simply the string/array starting from just after that character and going on to the end. I'm not familiar enough with Win32 API calls to know if there is another way.

Thanks, to retrieve the file name with extension, it goes as follows:
Code:string f = "C:\\Windows\\Desktop\\picture.jpg"; int i = f.find_last_of('\\'); if (i != string::npos) f = f.substr(i+1); // f contains the result :)
WinApi solution:
Also, see the many other Path_ functions. Very useful.Code:TCHAR szPath[] = TEXT("c:\\dir1\\file.txt"); PathStripPath(szPath); // Result: szPath == "file.txt" TCHAR szPath[] = TEXT("C:\\TEST\\sample.txt"); PathRemoveFileSpec(szPath); // Result: szPath == "C:\TEST"
GetFileTitle-returns string system would display for filename
GetFullPathName-given a filename returns full path for file.
GetLogicalDriveStrings-returns strings for all valid drives
GetLongPathName-converts shortpath to longpath
GetShortPathName-converts longpath to short path
