  • How, by telephone? There is no way that you can use the keyword "call" to call an exe.

  • Are you using a .Net application to call the VB6 application?

    If so, the exception message would indicate that the error is coming from the VB6 executable.

  • As Karen indicated, VB 6 questions are off-topic here and need to be posted in another forum.

    In addition, I would also like to politely ask that you to close out your threads in the future by marking those posts that are most helpful to your questions. You may find that people are more inclined to provide assistance if you give them credit for their answers and less inclined when you simply abandon them.

  • Including a snip of the offending code makes it easier for people to assist you.
