The thing is I am on a mac and don't know how to use an F8 in that case. Could anyone tell me how can I do that otherwise and http://stackoverflow.com/questions/16398261/how-to-check-which-line-of-vba-code-is-causing-errors how do I know which line is causing problems with execution? debugging vba excel-vba-mac share|improve this question edited May 6 '13 at 12:19 David Zemens 30.8k72755 asked May 6 '13 at 11:56 seigna 661310 1 See this: answers.microsoft.com/en-us/office/forum/… –David Zemens May 6 '13 at 12:20 add a comment| 3 Answers 3 active oldest votes up vote 4 down vote To check which line is giving you the error, you can use the ERL property. See this sample code below. Sub sample() Dim i As Long On Error GoTo Whoa 10 Debug.Print "A" 20 Debug.Print "B" 30 i = "Sid" 40 Debug.Print "A" 50 Exit Sub Whoa: MsgBox "Error on Line : " & Erl End Sub For this to work, you will have to number the code lines as I have done above. Run the above code and see what happens. share|improve this answer answered May 6 '13 at 13:24 Siddharth Rout 91k11102146 add a comment| up vote 2 down vote Sub Main() Dim lNum As Long On Error GoTo ErrHandler lNum = 1 / 0 ErrExit: Exit Sub ErrHandler: Debug.Print Err.Description Stop Resume End Sub When you
generally put more focus on the coding part and getting the desired result but during this process we forget http://www.exceltrick.com/formulas_macros/vba-on-error-statement/ an important thing i.e. Error handling. Error handling is an important part of every code and VBA On Error Statement is an easy way for handling unexpected exceptions in http://www.excel-easy.com/vba/examples/error-handling.html Excel Macros. A well written macro is one that includes proper exception handling routines to catch and tackle every possible error. Error handling is important because in case of on error any unexpected exceptions your code doesn’t break. Even if any fatal unexpected error occurs in the code then also you should ensure that the code should terminate gracefully. Definition of VBA On Error Statement: On Error statement instructs VBA Compiler, what to do in case any runtime exception are thrown. Syntax of On Error Statement: Basically there are checking error vba three types of On Error statement: On Error Goto 0 On Error Resume Next On Error Goto
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 objects. We call the Range objects rng and cell. Dim rng As Range, cell As Range 2. We initialize 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 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 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 'InvalidValue:' upon hitting an error (don't forget the colon). Add the following code line: InvalidValue: 4. We keep our error code simple for now. We display a MsgBox with some text and the address of the cell where the error occurred. MsgBox "can't calculate square root at cell " & cell.Address 5. Add the following line to instruct Excel VBA to resume execution after executing the error code. Resume Next 6. Exit the Visual Basic Editor and test the program.
