Excel Vba On Error Resume
but, i keep getting errors 'index out of range' i just want to make a combo box that is populated by the names of worksheets which contain a querytable For Each oSheet In ActiveWorkbook.Sheets On Error GoTo NextSheet: Set qry = oSheet.ListObjects(1).QueryTable oCmbBox.AddItem oSheet.Name NextSheet: Next oSheet I'm not sure whether the problem is related to nesting the On Error GoTo inside a loop, or how to avoid using the loop vba error-handling vba do until error share|improve this question asked Oct 4 '11 at 19:51 justin cress 5331921 add a comment| 9 Answers 9 active oldest votes up vote 11 down vote accepted The problem is probably that you haven't resumed from the first error. You can't throw an error from within an error handler. You should add in a resume statement, something like the following, so VBA no longer thinks you are inside the error handler: For Each oSheet In ActiveWorkbook.Sheets On Error GoTo NextSheet: Set qry = oSheet.ListObjects(1).QueryTable oCmbBox.AddItem oSheet.Name NextSheet: Resume NextSheet2 NextSheet2: Next oSheet share|improve this answer answered Apr 27 '12 at 19:07 Gavin Smith 1,690616 add a comment| up vote 7 down vote As a general way to handle error in a loop like your sample code, I would rather use: on error resume next for each...

generally put more focus on the coding part and getting the desired result but during this process we forget an important thing i.e. http://www.exceltrick.com/formulas_macros/vba-on-error-statement/ Error handling. Error handling is an important part of every code and VBA http://www.excel-easy.com/vba/examples/error-handling.html On Error Statement is an easy way for handling unexpected exceptions in 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 any unexpected exceptions your code doesn’t break. Even if on error 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 three types of On Error statement: On Error Goto 0 On Error Resume on error goto 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 th
