This function is supposed to search the computer for a certain file which in my program is file 'a'. There are problems with my function though, and if anyone could give me pointers I would be grateful.

well, file.cFileName contains the 'fully qualified path to folder'.

use _splitpath() to extract the path and filename:

http://msdn.microsoft.com/en-us/library/e737s6tf%28v=vs.71%29.aspx


line 7 is wrong. Use strcmp() with the filename (extracted with _splitpath())

http://cplusplus.com/reference/cstring/strcmp/?kw=strcmp

Like so:

1

if(0 == strcmp(fname, "a")) // Well typo if(0 == strcmp(fname == "a")) // Note the ""

//if(0 == strcmp(fname == "a")) //¿?
if(0 == strcmp(fname, "a"))


@OP: Learn to indent your code, the mistake is obvious.
Also, `<fully_qualified_path_to_folder>' ¿are you serious?

Where the heck did the a come from? And anyway, you can't convert a string to a character. What the heck are you talking about?
coder777 (8444)
the a came from your first post line 7.

And anyway, you can't convert a string to a character.
what is this refering to?

Follow the link how to use splitpath. Here's an exampl for it:

#include <stdlib.h>
#include <stdio.h>

int main( void )
{
   char fname_from_fully_quallified_path[_MAX_FNAME];

   _splitpath(file.cFileName, NULL, NULL, fname_from_fully_quallified_path, NULL);
}



As I mentioned above <fully_qualified_path_to_folder> <= file.cFileName. You don't get that?

read this for how to use ShellExecute:

for http://msdn.microsoft.com/en-us/library/windows/desktop/bb762153%28v=vs.85%29.aspx

handle -> HWND
leave that NULL!

CoInitializeEx? why? This is plainly wrong in a loop
and why this secon ShellExecute?
