I would like to load a vb.net dll or exe into memory and then call functions in that program from another program or vb script.
The reason for doing this is that the vb.net program gets called fairly often as it is updating fields in a database as people are entering dates.
I figured that if the code or functions were already in memory, the process would take a lot less time so the program itself wouldn't have to load each time.
Any help would be appreciated. Thanks. John

The 1st time you use routines in a library (which is what you are essentially describing) the library gets loaded. It stays loaded until some more important process needs that RAM.

Typically, .DLLs contain synchronous calls, and .EXEs contain asynchronous calls.
