Error Handler For Finding Values On Each Worksheet

Dec 11, 2007

I 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.

Even Handler Causes Run-time Error 5

Apr 5, 2013

I 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

[Code]....

Reset Error Handler

Sep 21, 2007

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

How To Improve VBA Numerical Error Handler

Mar 21, 2012

how 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

Error Message / Handler For Calendar

Oct 11, 2009

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)

Resume VBA Code From Error Handler

Oct 23, 2008

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.

Sub proCheckVesselCodes()
Sheets("Sheet4").Select
Range("K1").Value = "Check"
Set varRange1 = Range("A1")
fctCountNrRows
varRow1 = varRow
varRow2 = 2

jump:
On Error Goto addvessel...............

Error Handler For Incorrect Password (Protected Sheet)

Feb 1, 2007

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:

Catch An Error And Reset The Entire Code To The Very Beginning And Skip That Entire Entry

Jun 5, 2008

I want to catch an error and reset the entire code to the very beginning and skip that entire entry. When I use "Next fieldSheetName" I get "Next without For," error 1004. Searches tell me I have an open block somewhere, but that's not true. Removing that statement (and having the loop iterate as normal) has no error at all.

Dim employeeName As String
Dim fieldMax, x, y As Byte ' Counters mostly
Dim workedHours, fieldSheetName As Integer

fieldMax = 204 ' Row number to stop on in the field time sheet
row = 4 ' Row specification for field time sheet. Begin at row 4 to ignore headers
' and start on the first name. This should not be changed!
Col = 3 ' Start at column 3 then increase by one to start going to next time entry

' RESET HERE!
For fieldSheetName = 4 To fieldMax Step 8 ' This is our MAIN loop. It iterates from 0 to fieldMax, which is 204...........

Error Handler's: To Error Or Not To Error

May 11, 2006

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.

Freezing Row With Catch?

Dec 18, 2013

I am looking to freeze row 18 in an excel sheet, however in doing so this really limits the amount of rows below row 18 that can be viewed and scrolled through.

I would like to know if there is any way that you could freeze row 18 and when you scroll down on the worksheet, you can scroll down past rows 1-17 and when row 18 reaches the top row it would lock there? And you would then be able to continue scrolling down the worksheet beyond row 18..

Catch Deleted Row

May 19, 2008

I want to catch if the user has deleted a row. There is a need to know when a row is deleted and what the data was in that row. So, what I'm trying to do if a row is deleted is to undo the action and then change the font of all data in that row to have the strikethrough effect. This will enable others looking at the workbook to know that the information in the row existed but is no longer relevent.

So, the code is something like this:If row deleted Then
Application.Undo
Target.Font.Strikethrough = True
End If

UserForm: File/Path Access Error & I/O Error

Dec 19, 2006

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.

How To Catch Last Populated Cell In A Row

Feb 12, 2013

I have to create a formula to fine difference between 2 numbers.

There are columns A to Z.

Values will be populated in A1 to Z1. Sometimes the value will stop in between itself. For example H1.

So, I need a formula to catch the last populated cell (H1 in our case) and then find the difference between the value in its previous column.

H1-G1 should be the result I should get.

Emulating Try / Catch Procedure In VBA

May 6, 2014

I have a VBA procedure in Excel that opens PowerPoint presentations and searches each slide for embedded objects, opens, and attempts to save the objects as separate files utilizing the following statement:

Shape.OLEFormat.DoVerb Count

Where Count is the "Open" verb. 90% of the time it works great but there are times where the object simply wont open so the application just stops. I don't get any errors so I don't see how I can trap for this incident.

What I would like to do is emulate something similar to C#'s Try/Catch function.

Is there a way to do something like this in VBA?

Catch 22 - I.e. Last Entered Value In A Given Range

Oct 7, 2008

let's suppose I have a prefixed range like A1:A300 in which periodically I need to enter some records (normally numbers but also sometime blank cells - i.e. void no entries); so imagine you have an array of cells in which I want to catch by mean of a formula or a macro the last entered significative record (i.e. a number); the objective is obviously to catch the last significative record in that given range having numbers in it (i.e. leaving out any blank cells in between); no other clues to approach the problem are given: do you think it's possible to sort out somehow this tricky problem ?

example:

1
34
67
#
45
#
#
545
#
22

where # stands for blank cell

how to catch 22?

Vlookup For Date Not Finding It. #N/A Error

Jun 6, 2008

I haven't had issues with vlookup on other worksheets, but this one is giving me trouble. I have attached the excel file for your consideration.

The lookup value is in cell U2, formatted as a date
The table array is V2:Z19
The column index number is 2 for C3
False lookup


I've tried the formula with and without the text function for the date and I've also tried different formats for the dates in columns V to Z because I know the format of the cells have to match for vlookup. It is very frustrating because this should be simple, but it is messing up.

Catch/Trap Formula Errors

Sep 15, 2006

I am trying to find some solution on frequent errors , that come up when one copy, or drag formulae.
Sometime the error doesn’t appear on surface, but after digging you realize that some formula is not pointing to correct
cells.

I want to create a macro which will do following things :

1. It will go to each cell in the selected range, and compare the cell’s formula with that of the cell on its right and left.
2. If the formulae are not similar it should change the color of that cell.

Basically, I am trying to catch logical errors. However I don’t know how to approach this problem? Is there any in-built functionality in Excel that can do this task ?

Open File Macro, Error - Incrementing File Name

Feb 2, 2007

When it opens the desired file, it increments the file name by 1 each time it is opened (via the macro).

Example;
The first time it is opened you see the file name in the header read "P'Binder L&T Pages" for a moment, then it changes to "P'Binder L&T Pages1"...
I close the file and open it again (via the macro), and see the file name in the header read "P'Binder L&T Pages" for a moment, then it changes to "P'Binder L&T Pages2"...
The file name continues to increment on every opening until the PC is rebooted, then it starts at 1 again.

Sub OpnLTpages()

Dim wb As Workbook
Dim AlreadyOpen As Boolean

AlreadyOpen = False

For Each wb In Workbooks 'Scan open workbooks
If wb.Name = "P'Binder L&T Pages.xls" Then ........................
