Visual Basic for Applications Reference Visual Studio 6.0 On Error Statement See Also Example Specifics Enables an error-handling routine and specifies the location of the routine within a procedure; can also be used to disable an error-handling routine. Syntax On Error GoTo line On Error Resume Next On Error GoTo 0 The On Error statement syntax can have any of the following forms: Statement Description On Error GoTo line Enables the error-handling routine that starts at line specified in the required line argument. The line argument is any line label or line number. If a run-time error occurs, control branches to line, making the error handler active. The specified line must be in the same procedure as the On Error statement; otherwise, a compile-time error occurs. On Error Resume Next Specifie

Also, VB6 features in-code labels that can be used to create confusable “jump” patterns. These patterns are on error complex to read in VB6 and need to be removed from the resulting code for the sake of maintainability. The Visual Basic Upgrade Companion is able to remove unstructured “spaghetti code” and convert it to structured .NET statements. All unused labels are removed from the resulting code, plus the most commonly used “On Error” patterns are currently recognized and replaced for native .NET equivalent on error statement “try … catch” blocks. As part of the full conversion of the Visual Basic 6 Error handling schema (On Error ... Goto) to .NET, it is also necessary to convert the Err Object. The following VB6 extract shows a simple usage of the “On Error” statement to avoid a possible division by zero. The flow control of this source code extract will jump to the “ErrorHandler:” label in case there is an arithmetic error. Original VB6 source code Public Sub ErrorHandling(arg1 As Integer) On Error GoTo ErrorHandler Dim var1 As Integer var1 = 1 / arg1 MsgBox var1 MsgBox arg1 Exit Sub ErrorHandler: MsgBox Err.Description, , "Error" End Sub The Upgrade Wizard converts it using the same error management statements as in the original VB6 source code. VB.NET code generated by the Upgrade Wizard Public Sub ErrorHandling(ByRef arg1 As Short) On Error GoTo ErrorHandler Dim var1 As Short var1 = 1 / arg1 MsgBox(var1) MsgBox(arg1) Exit Sub ErrorHandler: MsgBox(Err.Description, , "Error") End Sub The Visual Basic Upgrade Companion is able to generate VB.NET source code using the .NET “Try Catch” blocks by applying special refactor techniques, as well as t
