These two lines are kicking my ass:



g_sImgLoad is a char* that stores the result of the function vdOpenFilDialog(), which is used to browse Windows for a file.

The second line writes a 1 or a 0 to the clipboard, depending on whether the file exists or not. For some reason, I always get 0 on the clipboard, even though when I paste the filename into Windows, it shows me the image.

What's the problem here?

Thanks.

Check to see what g_sImgLoad is before sending it to dbFileExist().

As I said, I tried g_sImgLoad in Windows and it showed me the file. I also checked it in the debugger and it appeared to be fine.

If the string that your file open dialog returns contains backslashes as separators, then replace them with double slashes before you pass them to dbFileExist.

I will test this a bit more when I get home from work, because dbFileExist sometimes returned zero on first try and one on the second try which is rather strange. However, backslashes will surely be a problem.

You only require double backslashes when writing string literals to prevent escaping of the string when you actually want to write a backslash character; Once it's in a string then it doesn't matter.

Also I think Zoto has now fixed the issue, nice of him to post notifying us .

I was just getting to that!

Contrary to what I thought (thanks to Benjamin), the problem was that I was passing a pointer back from the dialog function. Silly me.

My experience is that if I pass a simple backslash-separated path to any file handling function, it does not work. Maybe it's only on my system but it really matters.

Anyway, I'm glad that the issue is solved.
