Visual basic and DOS

[alifyag]

Hello,
The following code gets executed when i click on cmd_Execute


Private Sub cmdExecute_Click()
Shell ("perl gps_field_VB.pl " & sFile & " " & "ams.xls " & final_lat & " " & final_long)
End Sub

where sFile, final_lat, final_long all are defined.
The Dos window pops up in minimised mode and the perl script runs perfect.

However since the script takes some time to process I want to display a message in the status bar saying "File Processing" when the script is running and then display "File Processed" when the script has finished running.

How do I do it. I am using VB6 and I have Windows 98.

Thanks a ton.
Al

Explore the CreateProcess api: You have to create the process, hold onto the process handle, and loop (with Sleep in the loop) untill GetExitCodeProcess succeeds (which indicates the process has terminated, returning an exit code).
