I have a declare statement in my COM component compiled in VB:<BR><BR>Private Declare Function CALPROP Lib "Caldll.dll" (ByVal text As String, a1 As Single, a2 As Single) As Single<BR><BR>This file Caldll.dll (compiled in FORTRAN) is residing in the same folder as the COM component. When I call a method, i get "caldll.dll file not found".<BR><BR>Can somebody help me with this. <BR>CLARIFICATION: this dll "ca;dll.dll" is compiled in FORTRAN, so it is NOT a registerable component.<BR><BR><BR>
