Hi,

I have a macro in my excel worksheet that I recorded for excel solver.

Now I am trying to get that macro into my vb6 application, but vb6 doesn't recognize the syntax from my macro

Looks like you are going to need to write a Solver Sub manually to "recreate" what the solver did for you in Excel.

alternatively...this link looks promising
