Trapping Errors at Run-Time Before you can do anything to deal with a run-time error, you need to capture the error. You use the On Error statement to enable an error trap.

  • For example, vbObjectError + 1001.

If the value Err.Number is nonzero, the operation caused an error and the program can take special action. On Error Resume Next Vba Regardless of the approach you take, you must always ensure that private data within the class is valid and that code within the class cleans up any local or module level On Error Goto 0 You’ll be auto redirected in 1 second.

That is, when a procedure throws an exception, it can nest another exception inside the exception it's raising, passing both exceptions out to the caller. check my blog Thanks Mon, 10/08/2012 - 11:13 — buzz4rd (not verified) how to fix error vb6 it's a great tutorial. fnum = FreeFile Open filename For Input As fnum ' The file is now open.
