Errors and Error Handling When you are programming an application, you need to consider what happens when an error occurs. An error can occur in your application for one of two of reasons. First, some condition at the time the application is running makes otherwise valid code fail. For example, if your code attempts to open a table that the user has deleted, an error occurs. Second, your code may contain improper logic that prevents it from doing what you intended. For example, an error occurs if your code attempts to divide a value by zero. If you have not implemented error handling, Visual Basic halts execution and displays an error message when an error occurs in your code. The user of your application is likely to be confused and frustrated when this happens. You can forestall many problems by includi

A good article is the one of CPearson.com However I'm still wondering if the way I used to do ErrorHandling was/is completely wrong: Block 1 On Error Goto ErrCatcher If UBound(.sortedDates) > 0 Then // Code Else ErrCatcher: // Code End If The if vba on error clause, because if it is true, it will be executed and if it fails the Goto will go into the Else-part, since the Ubound of an Array should never be zero or less, without an Error, this method worked quite well so far. If I understood it right it should be like this: Block 2 On Error Goto ErrCatcher If Ubound(.sortedDates) > 0 Then // Code End If Goto hereX ErrCatcher: //Code Resume / Resume Next / Resume hereX hereX: Or even like this: Block 3 On Error Goto ErrCatcher If Ubound(.sortedDates) > 0 Then // Code End If ErrCatcher: If Err.Number <> 0 then //Code End If The most common way I see is that one, that the Error "Catcher" is at the end of a sub and the Sub actually ends before with a "Exit Sub", but however isn't it a little confusing if the Sub is quite big if you jump vice versa to read through the code? Block 4 Source of the following Code: CPearson.com On Error Goto ErrHandler: N = 1 / 0 ' cause an error ' ' more code ' Exit Sub ErrHandler: ' error handling code' Resume Next End Sub Should it
the wrong time. The application may crash. A calculation may produce unexpected results, etc. You can predict some of these effects and take appropriate actions. Some other problems are not under your control. Fortunately, both Microsoft Excel and the VBA language provide various tools or means of dealing with errors. Practical Learning:Introducing Error Handling Open the Georgetown Dry Cleaning Services1 spreadsheet and click the Employees tab Click the Payroll tab Click the TimeSheet tab To save the workbook and prepare it for code, press F12 Specify the folder as (My) Documents In the Save As Type combo box, select Excel Macro-Enabled Workbook Click Save Introduction to Handling Errors To deal with errors in your code, the Visual Basic language provides various techniques. One way you can do this is to prepare your code for errors. When an error occurs, you would present a message to the user to make him/her aware of the issue (the error). To prepare a message, you create a section of code in the procedure where the error would occur. To start that section, you create a label. Here is an example: Private Sub cmdCalculate_Click() ThereWasBadCalculation: End Sub After (under) the label, you can specify your message. Most of the time, you formulate the message using a message box. Here is an example: Private Sub cmdCalculate_Click() ThereWasBadCalculation: MsgBox "There was a problem when performing the calculation" End Sub If you simply create a label and its message like this, its section would always execute: Private Sub cmdCalculate_Click() Dim HourlySalary As Double, WeeklyTime As Double Dim WeeklySalary As Double ' One of these two lines could produce an error, such as ' if the user types an invalid number HourlySalary = CDbl(txtHourlySalary) WeeklyTime = CDbl
