I recently need to call a C program from VB4, passing certain parameters
to and get some values back from & produce certain output to a flat
file.
But I have no ideas how to start. Do I have to first create my own DLL
or API including those C program and how to create DLLs?

Any advice with regard to this issue will be greatly appreciated.
