Directory search problem 1

[labnotes]

I have the attached code. When run and I find a file I test to see if I can write to it. If I can everything is fine. If I can't write to the file the program doesn't work. Any ideas?

Thanks

My first idea would be to step through the code in the debugger and see exactly what is going on. Is that what you mean?

Thanks - great idea. Now if I can get the debug to work.

Looking at your code, are you sure that you are not adding a *.* to the end of your path string unnecessarily ?


if(strcmp(wfd.cFileName,file)==0)
{
path[strlen(path)-3]='\0';
strcat(path,file);
FindClose(fh);
return;
}

Why do you remove the last 3 characters of path, which are *.* by replacing with '\n', and then immediately add *.* back again ?

You really need to step through this, and see what is hapenning. what compiler are you using ?

Do you need help with that? Give more details, it's pretty easy in most cases.

Here variable .file. is &quot;*.*&quot;.
Are wild characters allowed as parameters of strcmp???!!
