Hi Jerry,
I've also been struggling with this problem as the Geosoft documentation is
not very helpful on the use of VB. The solution for the geostd problem is to
delete all copies of geostd.dll from directories other than the one in which
you installed 4.3 and to ensure that the 4.3 directory (containing all the
Geosoft dll's) is included in your PATH environment variable. You can't just
put geostd.dll in your windows system directory as it requires other Geosoft
dll's to load properly, so if it doesn't also find these in the system
directory the load fails and you then get the misleading File not found
error message. (Misleading because it did find geostd, but it failed to load
properly).
If you're going to distribute a VB application for users who do not have an
Oasis licence, you need to use the (more limited) gx_oppi.bas function
definitions rather than those included in the VB samples and the gx_oppi.dll
file should be installed in the system or application directory, or the user
needs to run the OPPI setup program.
Hope that this helps
