Some handy file functions for use with MFC

These are some handy functions I use that wrap the SHLWAPI functions from Win32 SDK. All of these could be done with the individual calls, these functions just make it a little more convenient.

//
//	Returns the file portion from a path
//
CString GetFileOnly(LPCTSTR Path)
{
//	Strip off the path and return just the filename part
	CString temp = (LPCTSTR) Path; // Force CString to make a copy
	::PathStripPath(temp.GetBuffer(0));
	temp.ReleaseBuffer(-1);
	return temp;
}

//
//	Returns the folder portion from a path
//
CString GetFolderOnly(LPCTSTR Path)
{
//	Strip off the file name so we can direct the file scanning dialog to go
//	back to the same directory as before.
	CString temp = (LPCTSTR) Path; // Force CString to make a copy
	::PathRemoveFileSpec(temp.GetBuffer(0));
	temp.ReleaseBuffer(-1);
	return temp;
}

//
//	Adds a backslash to the end of a path if it is needed
//
CString AddSlash(LPCTSTR Path)
{
	CString cs = Path;
	::PathAddBackslash(cs.GetBuffer(_MAX_PATH));
	cs.ReleaseBuffer(-1);
	if(cs.IsEmpty())
		cs = BACK_SLASH;
	return cs;
}

//
//	Removes a backslash from the end of a path if it is there
//
CString RemoveSlash(LPCTSTR Path)
{
	CString cs = Path;
	::PathRemoveBackslash(cs.GetBuffer(_MAX_PATH));
	cs.ReleaseBuffer(-1);
	return cs;
}

//
//	Adds a folder path and file together to make a file path
//
CString AddPathAndFile(LPCTSTR Folder, LPCTSTR File)
{
	CString cs = Folder;
	::PathAddBackslash(cs.GetBuffer(_MAX_PATH));
	::PathAppend(cs.GetBuffer(_MAX_PATH),File);
	cs.ReleaseBuffer(-1);
	return cs;
}

//
//	Adds a .ext to the end of a file path
//
CString AddExt(LPCTSTR Path, LPCTSTR Ext)
{
	CString cs = Path;
	::PathAddExtension(cs.GetBuffer(_MAX_PATH),Ext);
	cs.ReleaseBuffer(-1);
	return cs;
}

//
//	Returns true if file exists or false if file does not exist
//
BOOL FileExists(LPCTSTR Path)
{
	return (::PathFileExists(Path));
}

//
//	Returns true if file is read only
//
BOOL FileReadOnly(LPCTSTR Path)
{
	DWORD nAttributes;
	if((nAttributes = GetFileAttributes(Path)) != -1) {
		if(nAttributes & FILE_ATTRIBUTE_READONLY)
			return true;
	}
	return false;
}

//
// Returns just the .ext part of the file path
//
CString GetFileExt(LPCTSTR Path)
{
	CString cs;
	cs = ::PathFindExtension(Path);
	return cs;
}

CString GetFileName(LPCTSTR Path)
{
	CString csFile = GetFileOnly(Path);
	if(!GetFileExt(csFile).IsEmpty()) { // Is there an extension
		::PathRemoveExtension(csFile.GetBuffer(_MAX_PATH));
		csFile.ReleaseBuffer();
	}
	return csFile;
}

//
// Exchanges one file extension for another and returns the new fiel path
//
CString RenameFileExt(LPCTSTR Path, LPCTSTR Ext)
{
	CString cs = Path;
	::PathRenameExtension(cs.GetBuffer(_MAX_PATH), Ext);
	return cs;
}
