Application-wide Error Handling
Feb 21, 2007
I am creating a rather large system that is as OOP as I am able to with VBA (Please let the next version of VBA use .NET!).
I have created an ErrorHandler object that deals with all logic/user errors and I have decided to include runtime errors in it's scope as well.
Now I have an object function to catch all errors as such:
Public Function CatchAll(E As ErrObject)
Select Case E.Number
Case xxx
...
Case Else
MsgBox E.Number & ": " & E.Description & vbCrLf & E.Source
End Select
End Function
Now I have added the following to every single procedure and function in my application, and have realised how ridiculous it is.
On Error Goto ErrorHandling
...
ErrorHandling:
ErrorHandler.Catchall Err
Is there a way to add a single global ErrorHandling statement somewhere in my code that will be called whenever an error is raised?
Perhaps in my main module that fires all code, can I put a small procedure that will handle the errors? Or as a function in my ErrorHandler class that I call on initialisation?

So the issue I am having is that I have a worksheet with two long rows of value. If the user enters the incorrect value, the program gives a error case of 1004. If and when this error occurs I want the program to send a MessageBox to the user then end the program. The problem that I am running into is that whenever I write On Error Goto... It Goes to the label whenever any runtime error occurs. My belief is that there has to be a way to only check for a runtime error on a single line of code rather than the entire sub.

My current code opens a file ("Report01.CSV") from the directories in column A (one at a time), and copies data into sheet 2.
The problem is that sometimes there is no ("Report01.CSV") file in one or more of the directories.
What I would like to add is an error handler that would remove the directory (delete that cell) that caused the error and continue with the loop. I.e. resume importing data from the other directories.
CODE:
Dim wrkMyWorkBook As Workbook
Dim lngRow As Long: lngRow = 1
Dim lngColumn As Long: lngColumn = 2
Do Until Sheets("Sheet1").Range("A" & lngRow).Value = vbNullString
Set wrkMyWorkBook = Workbooks.Open(Filename:=Sheets("Sheet1").Range("A" & lngRow).Value & "" & "REPORT01.CSV")
lngRow = lngRow + 1

The On Error GoTo works if there is only one instance of the text not being found but crashes if there is a second.
I have tried adapting code found here http://www.excelforum.com/excel-prog...ght=cells.find but can't get it to work exactly as i would like.
Here is an extract of my code. There are about 12 different cells.find in total.

I recorded a macro to save a worksheet as a PDF file
It works fine, except when the PDF file is already open - Excel returns an error message and stops.
Can I use some error handling code to prevent the error, maybe bring up a msgbox and exit the sub at the point where the error occurs?
The part of the code where it stops is:
ActiveSheet.ExportAsFixedFormat Type:=xlTypePDF, Filename:= _
"C:UsersDaveDesktopTestingDemo List.pdf", Quality:= _
xlQualityStandard, IncludeDocProperties:=True, IgnorePrintAreas:=False, _
OpenAfterPublish:=False

I am writing a code in VBA using getpivotdata function. It is working fine untill the value does not exist.
Dim pt As PivotTable
Sheets("Pivot2").Select
Set pt = ActiveSheet.PivotTables(1)
Cells(2,1).Value = pt.GetPivotData("ID", "GCB", "1", "Gender", "F", "9 box Rating_2012", NBArr(k)).Value
'the code is looping through the values in an array called NBArr
I have tried to handle this as follows:
If IsError(pt.GetPivotData("ID", "GCB", GCB1, "Gender", Gen1, "9 box Rating_2012", NBArr(k)).Value) = True Then
Cells(2,1).Value= "0"
ElseIf IsError(pt.GetPivotData("ID", "GCB", GCB1, "Gender", Gen1, "9 box Rating_2012", NBArr(k)).Value) = False Then
Cells(2,1).Value = pt.GetPivotData("ID", "GCB", GCB1, "Gender", Gen1, "9 box Rating_2012", NBArr(k)).Value
End If
However, even this is not working (in case when the function finds no value).

I'm looking for some direction with enhancing this code:
Code:
Case "L18"
Dim dfcust As String
Dim wshgrp As Worksheet
[Code]...
With this code, wshmain.range("Y18") is populated with the value associated with the vlookup. However, problems exist when the vlookup fails. If the vlookup fails, I don't want to try to populate wshmain.range, just simply .protect and abandon.

I am working on a worksheet with quite a few advisors who will be using the sheet, because of this reason I am trying to cover my back with as much error handling with my VBA script as possible. Where I am struggling is the following line:
Code:
Set cb = Workbooks.Open("wilm-dchome"UserName"DesktopCurrent projectPipeline Grouped.xlsm")
I want to have an error handler that says if this file cannot be found use the following line of code instead:
Code:
Set cb = Workbooks.Open(Application.GetOpenFilename())
It may even be just a simple if statement instead but I cant seem to find the answer.

In an error handling procedure, I want to be able to capture the name of the Module and Sub procedure (macro) that the error has occurred in.
Is there any way to do this, outside of storing the name of the Sub somehow in a variable?
The Err.Source method seems to only contain very broad information, such as "VBA Project" when an error is encountered.

If there are records meeting the criteria are found, they are to be copied to a 2nd worksheet. Otherwise, the remainder of the code is to be executed.
I am getting an error "No Cells were found" (which is true since the autofilter doesn't net any results) with the line highted in red.
Consider this snippit of
'
' courts
'
Courts:
Dim lcrtcopy As Long
End_RowDest = 0
wshV.Activate
ActiveSheet.Unprotect
With Worksheets("Crts_Temp")
If .FilterMode Then .ShowAllData 'disable advanced filter of data if applicable
End With..........

I've got some code that reformats a file that a supplier sends us. They seem to randomly change the structure, so I'm trying to make the code a bit more robust.
Part of the code uses MATCH to look for specific column headings, so I've got some error handling around this of the format:
On Error GoTo NoIncCol
Line using MATCH
On Error GoTo Exiting
where Exiting is my standard error handling (Close without Save) and NoIncCol is the same, but with an error message saying that the term the code was trying to MATCH can't be found. This works well for me.
In another part of the code, I need to check for another column heading, which so far has turned up in two different forms. At the moment I'm doing this as follows:
With Sheets("Sheet1").Range("1:1")
Set rFound = .Find("Term1")
If Not rFound Is Nothing Then
a = "Term1"
Else
This feels a bit clunky, and I don't really like having what is essentially error-handling in the middle of my code. But the only other way I can think of to do it is to use a GoTo, and I believe that's not really considered good practice either.

I have a UserForm (and associated code) to locate a specific entry in Column 'A' of a spreadsheet and insert a date, initials, and hyperlink to another file.
The basic code works fine, but did not account for the user entering a Job# that was not in the system, so I added an If/Else to account for this...
The additional code took the If (Job# not found) route every time...
Following many hours of searching this site and variations of the error handling code, I still can not get it to work.
So I'm asking for your assistance to point out why the error handling (based on other successful code found here) is not working for me.
'Insert Link
Private Sub CommandButton3_Click()
If TextBox1.Value = "" Then
MsgBox "Please Insert a Job#"
Exit Sub
ElseIf TextBox2.Value = "" Then
MsgBox "Please Insert Quoters Initials"
Exit Sub
ElseIf TextBox3.Value = "" Then
MsgBox "Please Insert Quote Date"
Exit Sub
The 'Find' part of the code is working, as the correct cell is selected after running the code... but it gives the error message, instead of executing the rest of the code...
If I remove the 'On Error Resume Next', it stops on the find block, where on inspection FindR = Nothing.
So if FindR does = Nothing, how did it manage to select the cell?

When I enter this formula I get a #VALUE! error. I think it's because cell AG46 has an IF formula that results in "blank" if 0. How do I fix this error so that it includes cell AG46 and if cell AG46 is blank it counts it as a zero?
=SUM(A12)-(AG46*8)(=40 is the answer I'm looking for)
=SUM(40)-(0*8)

I'm trying to add a little error handling in my code. I have a macro that, when running opens a number of workbooks. At the end of the macro, my code then closes all the workbooks I've opened.
I was wanting to create an error-handling procedure that displayed a message box, and then closed any workbooks that I've opened during the course of the macro. Obviously the error could trigger at any point, so not all workbooks may have been opened at the time
My code is as follows - I've tried On Error Resume Next in the error-handling code, but Excel still returns an error that it can't find the Incidents_MTD sheet when trying to close it.
Code:
On Error GoTo ReportError
code
code

I have a excel document that is very heavy with Data Validation List Boxes. Below is just one example. Error handling is what I am trying to figure out.
Description:
I have 3 List Boxes.
One list box data is based on data selected in the previous list box.
1st List Box uses this formula: =Series
2nd List Box uses this formula: =INDIRECT($C$2)
3rd List Box uses this formula: =INDIRECT($C$3)
It all works! HOWEVER....
If user decides to go back and change selection in first or second list box, and forgets to change the data in the second or third box, then data will be incorrect. How do I solve this problem?
Is there anyway to write something so it would give them an error message and instructing them to correct the data?

The following code shows the bare bones which illustrate my problem. The routine runs whenever the user enters a string which begins "Frm1=" and contains exactly three commas.
My problem is with the MsgBox which appears if the ErrorHandler is reached. With the following code the MsgBox requires two clicks on OK to dismiss it. If I change Resume to GoTo it requires only one. Is this normal? Is there any way of dismising the MsgBox with one click? ...

I have written a VBA procedure which loops through excel files in an array: in turn it opens the file, refreshes the data, saves the file and closes. I would like to write an error handler which stores the file which errored (copied from the loop iteration) and the error description to an array. The error handler should then close the file and continue with the next iteration - e.g.
Code:
If ActiveWorkbook.ReadOnly Then
ActiveWorkbook.Close
Next i
*Although a generic if error may be better.
My idea is that all files which errored in some way will be stored in an array which I can automatically print/send to a user so they can manually figure out the problem. (This element falls outside the range of this query).
Below is a simple example of my efforts which only contains one file in the array to make things simpler: the error handler section won't work, it's just there to show my thinking
Code:
Sub Refresh_CRIS()
On Error GoTo Errorhandler
Dim routepath As String
routepath = "
chdfsSharedAreaPrivateTest"
ChDir routepath
[Code] ........
Errorhandler:
On Error Resume Next
Failed = Array(i)
If ActiveWorkbook.ReadOnly Then 'Just an example for testing
ActiveWorkbook.Close
Else
MsgBox "Pivots which failed to refresh:" & Failed '& ", ", 0, "Debug" 'Test with msgbox
End If
End Sub

I am currently creating a database which involves using a macro to create new worksheets in the workbook. When the macro is run and a work sheet is being inserted, an input box asks the user for a worksheet name.
As you can imagine, the worksheet does not like it when the worksheet name input by the user, is the same as one already existing and so throws up a 1004 error.
In order to resolve this error I have included an error handling code to request the user to input a differnet worksheet name, as the one previously inserted exists.
My problem: It all works fine until the user types in an existing worksheet name twice, so once initially and again when the error handler has prompted a second attempt. On the second incorrect input a 1004 error warning is displayed.
I would like the error handler to keep repeating until a worksheet name that doesn't exist is inserted by the user. Is this possible?
My code so far:
Sub NewTrancheSheet()
'
Sheets("Tranche Sheet Template").Visible = True
Sheets("Tranche Sheet Template").Select
Sheets("Tranche Sheet Template").Copy Before:=Sheets(1)
Sheets("Tranche Sheet Template (2)").Select
Sheets("Tranche Sheet Template (2)").Move After:=Sheets(Sheets.Count)
Sheets("Tranche Sheet Template (2)").Select.................

Before I go into details I am working in one workbook with several worksheets(Tabs) in the workbook. I have three Buttons on one tab. the button I am having trouble with is the third. I want to insert a column in a separate tab that contains approximately 87,000 rows of data. I then want to do a row count and select the empty cells in the inserted column and put a formula in there. I have tried a loop VBA code and it works, but it takes about 30 minutes to run all the way through. The underlined portion is what is higlighted with error 1004: Application-defined ro object-defined error. I am not sure how to fix this. This is what I have now:

use code tags around code. Posting code without them makes your code hard to read and difficult to be copied for testing. Highlight your code and click the # at the top of your post window.
