Determining the exact directory path [modified]

capricious_001

Hi there, I am trying to use CreateFile to open up a file handle however in some instances it doesnt work. Is there a way to convert a file location string into its exact case-sensitive string? For example.

lszLogFile = "C:\\TeSt\\TeSt.txt";

HANDLE hLogFile = NULL;
hLogFile = CreateFile(lszLogFile, GENERIC_READ, FILE_SHARE_READ, NULL, OPEN_EXISTING, 0, NULL);

lszLogFile is the actual parameter that works with create file and a handle is created, however if

lszLogFile = "C:\\test\\test.txt";

Then a handle will not be created. Is there a way to find out what the actual Directory string is? Thanks guys, Robbie -- modified at 13:10 Monday 19th June, 2006 Added the extra backslashes, and no that wasnt the problem.

Sure your problem is case related, not a lack of \ characters? Steve S Developer for hire

Should be:

lszLogFile = "C:\\test**\\**test.txt";

This should be:

lszLogFile = "C:\\TeSt\\TeSt.txt";

Why not? Have you checked the return value of GetLastError()?

It's whatever value you have assigned to lszLogFile.

lol nono, the path directory is correct. I just forgot the extra backslash in this example. I tested it. having lszLogFile = "C:\\TeSt\\TeSt.txt"; works rather than having all the characters as lower case. So really the question is how do i retreive the case sensitive file path of that file -- modified at 13:09 Monday 19th June, 2006 I wrote that piece of code in my original post on the fly. I hate copying and pasting my code because its just too much too read.

OK. I've read your modified post. Now it looks like a "chicken-and-egg" question though.

To retrieve the so-called *exact* file path, you need a valid file handle and pass the valid handle into some API. To get a file handle without knowing the *exact* case-sensitive path (in your case), you can only input the path in case-insensitive form which results in failure (in your case). Anyway, my system works very well with both your code snippets. :->

I used GetLastError() and figured out that it was an issue with my type-casting, but I fixed it lol. Thanks for the help.

But copy/paste is the preferred method as needless posts can be avoided. You only need to paste the relevant snippets, not an entire program.

Windows file systems are not case-sensitive. If C:\test\test.txt is failing, it's due to something else, not the case of the letters. Check the value of GetLastError()
