The information in this article applies to:
This article was previously published under Q213789 SYMPTOMS
In Microsoft Excel 2000, when you run a Microsoft Visual Basic for
Applications macro that uses Automation objects, Visual Basic may not indicate that the macro has halted when a macro error occurs. In some
cases when this behavior occurs, Excel may appear to stop responding (hang).

The following macro starts Microsoft Excel, inserts a new workbook, and then inserts an ActiveX control on the worksheet. The code produces an error when it attempts to select a drawing shape that does not exist. The On Error statement at the beginning of the macro traps this run-time error message and allows the macro to continue.
Sub AddCheckBox()
Dim x As Object
' Begin error trapping.
On Error GoTo errHandler
' Create the Microsoft Excel Automation object.
Set x = CreateObject("Excel.Application.9")
' Make the Excel object visible.
x.Visible = True
' Add new workbook.
x.Workbooks.Add
' Create ActiveX check box control.
x.ActiveSheet.OLEObjects.Add "Forms.CheckBox.1"
' Select cell E10.
x.ActiveSheet.Range("E10").Select
' Code will error here.
x.ActiveSheet.Shapes(1).Select
' Display message box.
MsgBox "Macro Completed"
Exit Sub
errHandler:
' Activate this instance of Microsoft Excel, so message is visible.
AppActivate Application.Caption
' Display a message that an error has occurred.
MsgBox "An Error has occurred" & Chr(10) & _
"RunTime Error " & Err & " " & Error(Err)
' Resume processing of the macro.
Resume Next
End Sub
STATUSMicrosoft has confirmed that this is a problem in the Microsoft products that are listed at the beginning of this article. MORE INFORMATION
In versions of Excel earlier than Excel 97, when you initiate an OLE Automation statement such as CreateObject or GetObject, if a macro error occurs, the host or server program flashes to indicate that an error has taken place. The same behavior is seen in these earlier versions of Excel if a program is made visible and maximized. The only way to determine if the macro has stopped unexpectedly is to switch back to the server program.
