I have written a long bit of code, which works fine. I decided to add an error handler just in case of any errors. I have run through my code numerous times to confirm that there is no error, but the msgbox still pops up.
View 3 RepliesI have a userform that reads data from a sheet with thousands of records (lines) each record with some 30 cells (columns). I wanted the user to scroll up & down in the sheet, using the keyboard arrows and I wanted the userform to show the relevant record, where the cursor stands. For this purpose I created an event handler (Worksheet_SelectionChange) that identifies the scrolling, populates the form with the relevant record data and then returns the focus back to the sheet. The command I have used to send focus back to the sheet (so the user can keep scrolling) is:
VB:
AppActivate "Microsoft Excel" & " - " & ThisWorkbook.Name
Now comes the bizarre part... This macro can work perfectly for hours and then decide to "die", or can work on one computer but not the other (all with Excel 2007, BTW). When the macro dies (or if it does not work, to begin with), the debugger points to the command I mentioned, with an error message "Run-time error '5' , Invalid procedure all or argument."
how to make my macro "stable" (make it work always and on every computer)?
Unfortunately, I cannot upload the file, because it contains confidential data (and it is not in English...).
VB:
Private Sub Worksheet_SelectionChange(ByVal Target As Range)
lr = Cells(Rows.Count, 1).End(xlUp).Row
If Target.Column < 2 And Target.Row > 1 And Target.Row <= lr Then
crow = ActiveCell.Row

I have a piece of code with some error handlers in it but for some reason the error handler can't deal with a second error. The example code below suffers from the same problem in that it falls over when it tries to process the i = "w" line for the second time. If you F8 through the code the error handler works the first time but not the second. Why is this and what can I do to get it to keep going to erH when it hits the i = "w" line?
Sub test()
Dim i As Integer
testing:
On Error GoTo erH
i = "w"
erH:
i = 1
GoTo testing
End Sub
What I'm wondering is when it is a good idea to use Error Handler's. I've got maybe 50 procedures in the project I'm working on. Some of the procedures are merely parent procedures calling other procedures. Since other people will be using this workbook, I want there to be a way to troubleshoot if errors occur, but it almost seems bad form to have an Error Handler for EVERY single procedure. Conversely, somehow, someone always finds a new and creative way to error out my workbook, and they don't understand the code and/or are not VBA literate. I can always fix afterwards, but solving the problem immediately over the phone is not ideal. I'm very new to debugging for other users. The workbook is currently in constant development/improvement used by only a handfull of users, but eventually it will need to be at some decent release stage, where the VBA code will be password protected, and I will not want the user getting into the code.
View 2 Replies View Relatedhow to improve the following error handling strategy and code samples so as to maximise its usefulness for the purposes described.
During function calculations in VBA, such as is done by numerical integrators, numerical run-time errors may occur, such as:
Err.Number = 5 Invalid procedure call eg. LOG(-5)
Err.Number = 6 Overflow
Err.Number = 11 Division by zero
My present strategy to address these errors:
Say the variable x is used in the function calculations, and some particular value of x causes one of the above errors to occur. After the above errors are trapped, the x value is increased slightly from its initial value, and the failed calculation line is retried (Resume). On the next error trap, the x value is decreased slightly from its initial value, and the calculation tried again. This way, the initial x value is cyclically changed by adding increasing magnitude increments of alternating signs, searching for the nearest x value which will allow the function calculation to be done without error. Thus it causes the x value to swing around the initial x value in a pendulum-like manner, but with a widening swing per pass.
So far, I have the following code:
Code:
ErrorHandler:
If Err.Number = 5 Or Err.Number = 6 Or Err.Number = 11 Then
If Initial = True Then

From my userform I use a calendar to input in two text boxes the "from" and the "to" dates and get a "custom" statement of activity by company.
If I input two dates that do not exist within my summary of sales how can I code in order to get an error message AND clear the text boxes. (textbox1&2)
Example: jan 07 to Dec07 do not exist/ Oct 09 does
"from" and the "to" dates = 01/01/2007 to 12/10/2010 would work (and it does)
01/07/2007 to 12/06/2007 does not exist anywhere then I want to see a message box to that effect AND the textboxes cleared for input of the new "from" date in textbox1
If Impossible at least can you help on an error handler? (on error resume does not work or at least I think it does not)
Before doing some modifications in a data sheet, I first check with the below code whether a certain list is complete or not using the VLOOKUP function. If I encounter a missing value in the list, a userform appears asking to fill out 3 data fields, which are then added to the original list to complete it. All of this works fine if only one line is missing; if there are two (or more) lines missing, all goes well untill the VLOOKUP function errors out on the second line missing.
I can't find out why everythign goes welll with the first missing line, but not with the second missing line.

Is it possible to create an Error Handler for the entire workbook, or do you have to put one on every sub routine?
View 1 Replies View RelatedI can not seem to find a good example of code for a try and catch error handler out on the web for something I am working on. Here is the code I am working with:
View 2 Replies View RelatedI am writing a macro to track stats in a workbook. The workbook has the check every tab in the given workbook, hidden and unhidden. In order to track the stats I find a column labeled "Read Dates" on each worksheet. The "Read Dates" column is not always in the same location so I have the macro Find the words "Read Dates". To make sure the cell the macro finds is the column label and not just another cell where someone may have used the words "Read Dates", I have an 'If/Then' statement checking the column to the left to ensure "Rev Mo" is there. If the state is true, the macro begins tracking stats. If the statement is false it attempts to find the next cell containing "Read Dates".
My problem occurs when the macro selects a sheet that contains no data or does not have the words "Read Dates". To help remedy this, I have an Errhandler that simply tells the macro to move onto the next worksheet. My problem is that there are several worksheets that do not have a cell with the value of "Read Date" so the second time the ErrHandler errors. Below is the section of the code I currently have an issue with.
Sub Begin_tracking()
'Error Handler
On Error Goto ErrHandler
WCount = Worksheets.Count
For i = 1 To WCount
If Worksheets(WCount - i + 1).Visible Then
Worksheets(WCount - i + 1).Select
Can anyone think of a better way of doing this so the entire workbook is worked or tell me how I can reset the Error Handler is it will move onto the next worksheet? I've looked into help on this forum to rest the ErrHandler but what I've found and tried has not worked. The ErrHandler may be invoked 2 times or it may be invoked 20 times depending on the workbook.
For some reason I thought this would be simple, but not as simple as I thought. I have a UserForm that enters data into a sheet, but before it is entered, the user is prompted for the sheet password (sheet is protected). What I tried to do is use an error handler to exit the sub if the password is incorrect, user hits Cancel, etc. Here is the code I am using:
View 10 Replies View RelatedI have written a number of UDFs, which work fine in my spreadsheet. Two of these are more complex, and I'm having a few problems...
When I run any VBA routine (i.e. control passed to VB), these two UDFs return #VALUE! errors, but I can't see why. As these are Functions, I can't think of a way to test where the error is being generated, like I would in a Sub
When I return to Excel, any recalculation fixes the problem, which makes me think something is declared incorrectly. All named cell references relate to other VBA functions, calling the relevant row / column numbers, and I think these are all correct. I've tried removing AS INTEGER etc, to avoid type mismatches, and adding APPLICATION in front of worksheetfunction...
Function precedentStart(Target As Range) As Integer
Application.Volatile
With ThisWorkbook.Sheets("sheet1")
Dim splitPrecedent As Variant, lookupI As Integer, rowI As Integer
precedentStart = .Cells(Target.Row, colOrigStart).Value
splitPrecedent = Split(Target.Text, ",")
For i = LBound(splitPrecedent) To UBound(splitPrecedent)
rowI = WorksheetFunction.Match(splitPrecedent(i), .Range("schedRefs"), 0)
lookupI = .Cells(rowI, colAdjEnd).Value
If lookupI > precedentStart Then precedentStart = lookupI
Next i

why the On Error GoTo statement only executes the first time an error occurs in the following
On Error GoTo CubeNotFound
For x = 2 To TotalRecords
Cells.Find(What:=WSID, After:=ActiveCell, LookIn:=xlFormulas, LookAt:=xlWhole, SearchOrder:=xlByRows, SearchDirection:=xlNext, MatchCase:=False, SearchFormat:=False).Activate
'Other actions are located here, but have been removed. These actions take place if the Find is succesful.
CubeNotFound:
Message = MsgBox("WS ID " & WSID & " was not found! Excel will continue with the next WS ID.", vbOKOnly, "WS ID NOT FOUND")
Next x
I have that statement there because if WS ID is not found then VB generates an error that the user won't be able to interpret, and also stops the code. I want VB to continue to the next record if one is not found.
I'm not sure why this is happening, but every other time I run this one specific macro, I get a "Run-time error '1004': Paste method of Worksheet class failed". I even tried running this macro, then running a different one, then running this again, but I still got the error every other time.
Every time I get the error, it highlights this line of
Sheets("Regenerate Request").Paste
This is all of the code up to where I get the error:
Sub YesRegen()
' after user has hit Yes on the RegenerateRequest macro, this posts the new request to

Application.Run "LogUnprotect"

see attached example. I am trying to write an error detection routine that iterates through worksheets that have numeric values for names (ignore text names or alphanumeric). Macro checks range on each numeric worksheet E3:E33 and is supposed to report back on the SummarySheet if any value other than 1 or 0 is found in range E3:E33 on any numeric-name worksheet. Code as follows:
[Code] ....
Problem is that it just reports EVERY worksheet as having an error when clearly most don't (none do I think in the attached example).
Try changing some of ranges E3:E33 to values other than 1 or 0, it still reports all sheets. Why the macro does not evaluate the range E3:E33 properly and just reports every worksheet as having an error?
See the attached sheet. I am trying to add together two figs which are linked to calculations which have formula built in to stop error messages when there is a 0 / 0 = #value type error. However when these two cells are added, if the cells are blank I get an error message. And if only one cell has a value, I get "" with my existing formula. what I need to do to get a result of 7 if for example cell A4 = "" + B4 =7. At the moment my formula shows "" in the sum total of these cells
View 5 Replies View RelatedOK, so I have a userform with some text boxes that I have specially formatted to accept only date values in the form of mm/dd/yy. By default they are blank. I have a check in one of my codes that looks like this
Code:
If DateBox vbNullString And DateValue(DateBox) > checkdate Then
M1 = "NEOPRENE" & Chr(13)
Else
M1 = "" & Chr(13)
End If
Where DateBox is this specially formatted TextBox and checkdate is a future date being checked against.So if DateBox has a value in it AND that value is greater than the date being checked against the returend string is Neoprene, otherwise it is blank.
Well the problem I have is when the first condition returns FALSE, i.e. when DateBox is empty, the DateValue half still gets evaluated and returns a type missmatch error or something like that because DateValue("") returns an error. I have line of code 8 times, one for Neoprene, squeegee, etc. So the name of the text boxes are each unique and I am using M1, M2, M3, etc.
For other reasons, use of "On Error Resume Next" doesn't work for this situation because it causes a result opposite to what I want to happen.
the if stattement works perfectly and does exactly what i want except when it comes to the else part. if there is no error the statements are run perfectly but if there is an error (in this case the error is generated when a match cannot be found in the spreadsheet) the else statement doesnt kick in and post the msgbox.
the code just crashes. and returns an error 1004 on the line i have highlighted in yellow
res = WorksheetFunction.Match(invvar, Columns(1), 0)
If Not IsError(res) Then
Me.txtClientID.Value = ws13. Cells(res, 7)
Me.txtNumber.Value = ws13.Cells(res, 7)
Me.txtDate.Value = ws13.Cells(res, 8)

I am trying to run create a simple macro that copies and paste special values - something I have done 100's of times but for some reason I keep getting an error message - even though I recorded the macro and didnt write it by hand - see below:

selection.PasteSpecial Paste:=xlPasteValues, Operation:=xlNone, SkipBlanks _

I have some code that, although works fine in Excel 2003, does not in Excel 1997. I receive this error when I try running it:
COMPILE ERROR:

Sub HPVAL()
Dim r As Range, myStr As String
myStr = "HP"
Set r = Cells. Find(What:=myStr, After:=ActiveCell, LookIn:=xlFormulas, LookAt _
:=xlPart, SearchOrder:=xlByRows, SearchDirection:=xlNext, MatchCase:= _
False, SearchFormat:=False)
If Not r Is Nothing Then
r = r.Value
While Not r Is Nothing
Set r = Cells.FindNext(r)
If Not r Is Nothing Then
r = r.Value
End If
Wend
End If
End Sub
It looks like Excel is getting hung up on the "SearchFormat:=" portion of the code.
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.
View 3 Replies View RelatedI have written a Excel (2003) that searches a worksheet for a string in any cell. If the string is not found, it uses the 'On Error GoTo' command to jump to a given label. It works fine on the first string not found. When it searches for the next non-existent string, it fails with:
'Run-time error '91':

I need to repeat these same steps (seen for row 5 below) for rows 5 to 50. My script worked until I hit row 35 and then I got the "compile error.." message.

the spreadsheet needs to be copied to a directory called "C:downloads" as it contains a ODBC query to itself (In reality, this is a query to an External Oracle Database)
On loading, it should pop up a simple userform, with a combo and two command buttons, which when pressed takes you to a (hidden) tab that displays a pivottable.
All works well until I try to close /save when 60% of the time, Excel encounters problems and closes and will not load up the file the next time until either quit excel or disable macros. Messages include "file/path access error", "I/O Error" or get restarts excel.
On a casual run through, I expect you might report back that "All worked ok for me". Please can you give it a bit of a thrashing, comment out the userform show, save the file (frequently) becuase i assure you it will break ultimately!
This is a brand-new file and I've tried it on about 5 different PC running different versions of Excel and generally get the same result.
