generally put more focus on the coding part and getting the desired result but during this process we forget an important thing i.e. Error handling. Error handling vba on error goto 0 is an important part of every code and VBA On Error Statement is vba error handling in loop 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 any fatal unexpected error occurs in the http://www.mrexcel.com/forum/excel-questions/229230-visual-basic-applications-if-error-show-msgbox.html code then also you should ensure that the code should terminate gracefully.

I have got following problem. This macro should paste from clipboard to cells(1,1). And if there is no data in clipboard, I would like it to display msgbox with test "Nothing to paste". What this keep doing is on error it will enter in cell(1,1) text: "MsgBox "Nothing to paste"" instead of displaying message. Could you please help me correct mistake? Many thanks in advance!!! Sub Paste() Cells(1, 1).PasteSpecial If Err on error goto Then MsgBox "Nothing to paste" End If End Sub excel vba error-handling share|improve this question asked Mar 28 '14 at 12:26 Petrik 3941317 it will enter in cell(1,1) text: "MsgBox "Nothing to paste"" instead of displaying message. - it's because your last action was copy this line of code and paste it in your sub. And this line is still in clipboard –simoco Mar 28 '14 at 12:34 add a comment| 2 Answers 2 active oldest votes up vote 0 down vote accepted Try clearing the clipboard after you paste your text so that the next run wont contain the same text that was just pasted. Sub Paste() On Error Resume Next Cells(1, 1).PasteSpecial 'Clear clipboard Application.CutCopyMode = False If Err Then MsgBox "Nothing to paste!" Err.Clear End If End Sub Here is another way that uses the MS clipboard more directly. First you need to add a reference to: Microsoft Forms 2.0 Object Library in your vba project. Public Declare Function OpenClipboard Lib "user32" (ByVal hwnd As Long) As Long Public Declare Function EmptyClipboard Lib "user32" () As Long Public Declare Function CloseClipboard Lib "user32" () As Long Sub Paste() Dim DataObj As New MSForms.DataObject DataObj.GetFromClipboard On Error GoTo ErrorHandler ActiveSheet.Cells(1, 1).Value = DataObj.GetText OpenClipboard (0&) EmptyClipboard CloseClipboard Exit Sub ErrorHandler: MsgBox "Nothing to paste!"

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.
