exist

[oex]

Is there an 'exist' function for directories? exist c:\dirpath without trailing backslash works but beeps :lol

Code Select Expand

    invoke  SHGetFileInfo, addr MyDir,
                            NULL,
                            addr sfi,
                            sizeof sfi,
                            SHGFI_DISPLAYNAME

Seems to work for directories, not sure if it is the best way...  returns 0 if the directory does not exist and 1 if it does

I know this is crude but I store the current path and change directory to a path to test. If it returns an error it does not exist. If it does not return an error I change back to the current path with a verified directory.

Use GetFileAttributes and test the return value for INVALID_FILE_ATTRIBUTES (error) then FILE_ATTRIBUTE_DIRECTORY.

FindFirstFile ?

[sinsi]

GetFileAttributes takes 1 parameter (the name) and returns a dword, no need to allocate structures then close handles.

:lol the only one I'd thought of was FindFirstFile.... let me rephrase which one's best

EDIT: Thanks Sinsi (and all :wink)will try that one then :bg

There are many ways to kill a bird  :bg  Didn't think about FindFirstFile.

[oex]

You can kill a bird with FindFirstFile? :lol

SHGetFileInfo is brutally slow and too much for this simple task. I'd go with Sinsi's suggestion. Searching also found this thread :
