- individual code for error handling Resume Next Use the Resume Proceed command to specify a jump point for continuing the program after error handling: ErrorHandler: ' ...
- The first form, On Error Resume Next , tells OOo to ignore all errors: No matter what happens, keep running and pretend everything is fine.
- Use Resume LabelName to continue running at some specified location (see Listing 62).
Process error Else ' ... OOo Basic provides a mechanism to modify this behavior (see Table 18 ). L'exemple commence par vérifier si le numéro de l'erreur correspond à celui qui est attendu (stocké dans la constante imaginaire ExpectedErrorNo), puis traite l'erreur en conséquence. It is cumbersome to check every mathematical operation before it is used.

"on Error Goto -1" The error information is cleared, so it isn't possible to check if an error occurred following the statement. LibreOffice Basic offers several methods to prevent the termination of a program when a run-time error occurs.
For example, dividing by a variable that at some point evaluates to zero will cause a run-time error. navigate here The Exit Sub command is required so that the error handler code would not be executed again. Care should be taken when you use the On Error Resume Next command as this dismisses all open error messages. The default error handler displays an error message and stops the macro.
The Error$ contains the text of the error message. If the problem is not fixed, the error will occur again. All exceptions thrown by UNO are caught by the Basic runtime system and transformed to a Basic error.

Listing 57: The error is cleared by the Resume Next statement.
Numerous examples and explanations demonstrate proper techniques and discuss known problems and solutions. Example: Sub ExampleReset On Error GoTo ErrorHandler Dim iNumber As Integer Dim iCount As Integer Dim sLine As String Dim aFile As String aFile = "c:\data.txt" iNumber = Freefile Open aFile If another error occurs, the system outputs a warning.
