hey, (like the subject line..lol)

i am having a bit of a problem with using my own DLL's in vb, I wrote it in VC++, and am trying to use it in vb, but i keep getting the error:
"Cant find DLL entry point in..."

now do you have any idea why this does that? Do you need to reference it or something? All i am doing to connect it to VB is add:
Code:
Private Declare Function add Lib "DLLTest.dll" (y As Integer, x As Integer) As Integer
in the general declarations, is this wrong? I dunno...

thanks
