Vbscript On Error Exit
as it usually happens I have to write a small script to check something. It opens Excel, writes something to it and closes it. But that's not the point. The point is that I cannot manage to write code for error handling. This script: Sub Work() On Error GoTo ErrMyErrorHandler Dim objExcelApp Dim wb Dim ws Set objExcelApp = CreateObject("Excel.Application") Set wb = objExcelApp.Workbooks.Add(True) Set ws = wb.Sheets(1) ws.Cells(1,1).Value = "Hello" ws.Cells(1,2).Value = vbscript error handling best practices "World" wb.SaveAs("c:\test.xls") objExcelApp.Quit() Exit Sub ErrMyErrorHandler: MsgBox Err.Description, vbExclamation + vbOKCancel, "Error: " & CStr(Err.Number) End Sub Work() gives this error: Line 2 is the line with the On Error statement. What am I doing wrong? Thank you. vbscript share|improve this question asked Jun 27 '11 at 7:45 Grigory 45911024 add a comment| 3 Answers 3 active oldest votes up vote 3 down vote accepted looks like you can not point custom label to error handler in VB Script. You can only use on error goto 0 '(raises exceptions) on error resume next '(ignores exceptions) if you use the second syntax, you can catch occruing exceptions via Err global variable: if Err.Number <> 0 then MsgBox "Exception occured: " & Err.Decscription share|improve this answer edited Jun 27 '11 at 8:43 answered Jun 27 '11 at 7:48 heximal 7,46822149 add a comment| up vote 3 down vote Heximal is correct that VBScript does not allow custom labels for error handlers. Using your example, you'd really be trying to do something like this. Sub Work On Error Resume Next Dim objExcelApp Dim wb Dim ws Set objExcelApp = CreateObject("Excel.Application") Set wb = objExcelApp.Workbooks.Add(True) Set ws = wb.Sheets(1) ws.Cells(1,1).Value = "Hello" ws.Cells(1,2).Value = "World" wb.SaveAs("c:\test.xls") objExcelApp.Quit() If Err.Number <> 0 Then ErrMyErrorHandler End Sub Sub ErrMyErrorHandler MsgBox Err.Description, v

On Error Statement Enables or disables error-handling.Syntax Copy On Error Resume Next On Error GoTo 0 RemarksIf you don't use an On Error Resume Next statement anywhere in your code, any run-time error that occurs can cause an error message to be displayed and code execution stopped. However, the host running the code determines the exact behavior. The host can sometimes opt to handle such errors differently. In some cases, the script debugger may be invoked at the point of the error. In still other cases, there may be no apparent indication that any error occurred because the host does not need to notify the user. Again, this is purely a function of how the host handles any errors that occur.Within any particular procedure, an error is not necessarily fatal as

Error Handling - on error goto Label? MCubitt (Programmer) (OP) 5 Nov 03 03:52 Within VBS, is it possible to provide my own error handling, such:..on error goto myerrorhandle..quitmyerrorhandle:if Err.Number=3 thenecho "Oh no, not good"elseecho "Not so bad, but not great."end ifquit RE: Error Handling - on error goto Label? tsuji (TechnicalUser) 5 Nov 03 04:55 Hello MCubitt,Vbs does not support On Error Goto Label directive. Instead, it is not difficult to implement the functionality. Something like this illustrate the idea.set fso=createobject("scripting.filesystemobject")on error resume nextset f=fso.opentextfile("nonexisting.txt")errcode=err.numbererr.clearselect case errcodecase 53call errorhandle_53'case etc...case elsemsgbox err.number & vbcrlf & err.description'do something / call some routineend select'some other stuffon error goto 0'do some other stuffset f=nothingset fso=nothingsub errorhandle_53'file not foundmsgbox err.number & vbcrlf & err.description'do something usefulend sub RE: Error Handling - on error goto Label?

There are various ways on handling errors in QTP. There are three possible kinds of error type one would encounter while working with QTP. Syntax Errors Logical Errors Run Time Errors Error Types: Syntax Errors: Syntax errors are the typos or a piece of the code that does not confirm with the VBscripting language grammar. Syntax errors occur at the time of compilation of code and cannot be executed until the errors are fixed. To verify the syntax one use the keyboard shortcut as Ctrl+F7 and the result is displayed as shown below. If the window is NOT displayed one can navigate to "View" → "Errors". Logical Errors: If the script is syntactically correct but it produces unexpected results. Logical error usually does not interrupt the execution but produces incorrect results. Logical errors could occur due to variety of reasons, viz- wrong assumptions or misunderstanding of the requirement and sometimes incorrect program logics(using do-while instead of do-Until) or Infinite Loops. One of the ways to detect a logical error is to perform peer reviews and also verifying the QTP output file/result file to ensure the tool has performed what it has intended to do. RunTime Errors: As The name states, this kind of Error happens during Run Time. The reason for such kind of errors is that the script trying to perform something but it is unable to do so and the script usually stops as it is unable to continue with the execution. Classic Examples for Run Time Errors are, File NOT found but the script trying to read the file. Object NOT found but script is trying to act on that particular object. Dividing a number by Zero. Arra
