Exception Handling

[lsmyth1717]

Does anyone know how to do exception handling in vb6. Do you use the Try Catch blocks. If so can someone show me a very quick example of this

There are no try/catch blocks in VB. I wish there was. VB.Net has them.

In VB, you use On Error. There are several ways to use it.

On Error Resume Next ' This will ignore errors and continue

On Error Goto LineLabel ' This will jump you to error handler

On Error Goto 0 ' This will turn off error handling

The best way (in my opinion) to use error handling is....

Public Sub ErrorHandlingExample()
  On Error Goto ErrorHandler

  Dim iTest as Integer

  iTest = iTest / 0

  Exit Sub

ErrorHandler:

  Call MsgBox(Err.Description)

End Sub

This is a brief description, you should look at the help files more a fuller understanding of error handling.
