Thank you prasad_som,

I found this works aswell....

	HANDLE Handle;
	WIN32_FIND_DATA FindData;
	Handle = FindFirstFile(fileName, &FindData);
	if(FindData.dwFileAttributes & FILE_ATTRIBUTE_DIRECTORY);
	else
	{
		Ptr = FindData.cFileName;
.....

Actually PathStripPath() is the right one to use na?

You can use this function,too. In addition to originally suggested.
Remember PathStripPath strips original string.

What made me think the PathStripPath better is that, in the docmentation of the PathFindFileName in MSDN, it says the function "Searches a path for a file name.". I think this will invoke some disc operation where as the PathStripPath only need to work on the buffer. I am not sure..... What do you think about this?

This means, searches path mentioned in buffer.

No, it doesn't.

Naveen R wrote:

As said earlier, both version works on buffer. But, PathStripPath strips(modifies) original buffer , passed as input. Which may be not needed. Again, need to use these functions according to need.

I think you missed some thing here...

Generally to find a string, use comparision APIs, say strcmp, CString::Compare and also APIs are available for case in sensitive comparing..

Actually i donno any API for this, but i'll you an algo for this,
1) Open the File as Random file
2) Move the file pointer to end of file (using seek method)
--inside loop
3) Decrement the pointer and read a char (to read the char before, using seek method)
4) check for delimiting chars (say space, or some thing else)
5) if not a delimiting char then append the char to a string
6) decrement the file pointer (to set to previous position, using seek method)
7) goto step 3 (have to decrement again, to get previous char)
8) if its a delimiting char then break the loop.
--end of loop
Now you got the last word in the file, but it'll be in reverse. So apply strrev and get the original string..

I tried this procedure but the decrementing the pointer and reading the data gives me data as -1

Use CFileDialog::m_ofn-->lpstrInitialDir .Modify your code like this,

CFileDialog dlg(TRUE, _T("dgl"), _T("Playlist"), OFN_FILEMUSTEXIST, "*.*", this);
dlg.m_ofn.lpstrInitialDir = "c:\\";//mention folder you want to display initialy
dlg.DoModal();
