Check for library exist or not.

I have a program with reference to MS Office libraries. If my program is installed in a computer without MS Office, How could I check that so that my program could run correctly?

Any function that hasn't been used won't load the dll needed for it until it actually happens, find an obscure function in the dll that does little (or doesn't do anything bad), give it values it can use to do little with (or not) and call the function, the standard "File Not Found" will happen if the library doesn't exist.

Error #53, "File Not Found".

Quickest way to know a DLL (even when it SHOULD exist) isn't loading correctly, either because it went bad or isn't there.

The Call [some API call here] is where you call your DLL or Any DLL for that matter. Typically, if you want to have a global function that does error testing then place a value (boolean) around the call:

DllCall = True
Call [DLL]
DllCall = False

Then in the CallDead routine:

if Err.Number = 53 Then replaces to if Err.Number = 53 And DllCall = True Then

The Resume Next will take the DllCall back to false, if it's not a serious error (like a bug in your code, no wait, it's not bug, it's an ISSUE, yes, thats it, ISSUE. Someone grab me a tISSUE).
