Is there a way to make a VB program run as a screen saver?
I noticed that a program I downloaded put two files in the windows directory a .scr file and a .ini file, but the actual .exe file is int's it's own directory.

The only difference between a Screen saver and a normal program is the extinsion.  Windows finds all programs with the .scr extension and lists them and their titles as Screen Savers.  You could make a program that is named .scr and it calls to an external .exe in a different directory.  The Settings part of the screen saver is sent as a command line switch /C .
And Example of this is:
         if Command$ = "/c" then frmSetting.show

Here is a useful api to hide the currsor

Declare Function ShowCursor Lib "user32" Alias _
"ShowCursor" (ByVal bShow As Long) As Long

bShow is either True or False

What exactly do you put in the program that you call the  visual basic screensaver.exe with? And do you just write it on a .bas and then change the file extension?

Well I made bas program and put the following in the sub main:

Dim returnvalue As Double
returnvalue = Shell("c:\windows\desktop\screensaver\GMscreensaver.EXE", 3)
AppActivate returnvalue
End

And then I changed the extension to the compiled program above to scr and selected it as my screensaver and it did call the listed program, but I got a runtime error # 6 overflow.

Plus it kept loading the screensaver program without waiting for the delay to start the screensaver that windows has. So I figure I got a bunch of missing code. What do I need to do?
