execution at a specified line upon hitting an error. Situation: Both programs calculate the square root of numbers. Square Root 1 Add the following code lines

to the 'Square Root 1' command button. 1. First, we declare two Range excel vba error handling not working objects. We call the Range objects rng and cell. Dim rng As Range, cell As Range 2. We initialize excel vba error handling line number the Range object rng with the selected range. Set rng = Selection 3. We want to calculate the square root of each cell in a randomly selected range (this range can be https://msdn.microsoft.com/en-us/library/5hsw66as.aspx of any size). In Excel VBA, you can use the For Each Next loop for this. Add the following code lines: For Each cell In rng Next cell Note: rng and cell are randomly chosen here, you can use any names. Remember to refer to these names in the rest of your code. 4. Add the following code line to the loop. On Error Resume http://www.excel-easy.com/vba/examples/error-handling.html Next 5. Next, we calculate the square root of a value. In Excel VBA, we can use the Sqr function for this. Add the following code line to the loop. cell.Value = Sqr(cell.Value) 6. Exit the Visual Basic Editor and test the program. Result: Conclusion: Excel VBA has ignored cells containing invalid values such as negative numbers and text. Without using the 'On Error Resume Next' statement you would get two errors. Be careful to only use the 'On Error Resume Next' statement when you are sure ignoring errors is OK. Square Root 2 Add the following code lines to the 'Square Root 2' command button. 1. The same program as Square Root 1 but replace 'On Error Resume Next' with: On Error GoTo InvalidValue: Note: InvalidValue is randomly chosen here, you can use any name. Remember to refer to this name in the rest of your code. 2. Outside the For Each Next loop, first add the following code line: Exit Sub Without this line, the rest of the code (error code) will be executed, even if there is no error! 3. Excel VBA continues execution at the line starting with 'InvalidValu
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 http://www.functionx.com/vbaexcel/Lesson26.htm Excel and the VBA language provide various tools or means of dealing with errors.

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 excel vba error 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(txtWeeklyTime) ' If there was an error, the flow would jump to the label WeeklySalary = HourlySalary * WeeklyTime txtWeeklySalary = FormatNumber(WeeklySalary) ThereWasBadCalculation: MsgBox "There was a problem when performing the calculation" End Sub To avoid this, you should find a way to interrupt the flow of the program before the label section. One way you can do this is to add a line marked Exit Sub before the label. This would be done as follows: 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(txtWeeklyTime) ' If there was an error, the flow would jump t

(It works but I'm interested to know what other people make of it and for any suggestions you might like to make.) The most important facts to realise are: When you use on error goto Label1 the procedure enters into a state of "I'm handling an error" as an exception has been raised. When it is in this state, if another "On Error Goto" label2 statement is executed it will NOT goto label2, but raises and error which is passed to the code that called the procedure. You can stop a procedure being in the "I'm handling an error" state by clearing the exception (setting err to nothing so the err.number property becomes 0) by using Err.clear or On Error Goto -1 ' Which I think is less clear! (NOTE that On Error Goto 0 is different from the above) Also important to note is that Err.Clear resets it to zero but it is actually equivalent to: On Error Goto -1 On Error Goto 0 ie Err.Clear removes an "On Error Goto" that is currently in place. So therefore it is mostly best to use: On Error Goto -1 as using Err.clear You would often need to write Err.Clear On Error Goto MyErrorHandlerLabel I use the above techniques with various labels to simulate the sometimes useful functionality that Visual basic TRY CATCH blocks give, which I think have their place in writ
