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

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]....

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.

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
[Code]....

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.
Sub proCheckVesselCodes()
Sheets("Sheet4").Select
Range("K1").Value = "Check"
Set varRange1 = Range("A1")
fctCountNrRows
varRow1 = varRow
varRow2 = 2
jump:
On Error Goto addvessel...............

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.

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:

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.

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...........

I wonder if there is a way to clear event handler code in a userform programmatically?
Haven't quite managed it yet.
Something like:
dim x as integer
With ThisForm.CodeModule
x = .CountOfLines
For 1 to x
.line = ""
Next x
End With

Is there an Event Handler that runs a macro whenever any control object in a worksheet has its state changed or whenever any checkbox is checked/unchecked. I want to have a method handle this outside of the checkbox since the number of checkboxes are dynamic and should not have to be individually coded by the user.

I have a workbook, that when opened the first time needs to prompt the user to save it. I got that working with no issues by using
Private Sub Workbook_Open()
SaveOnOpen
End Sub
where SaveOnOpen is a procedure in another module. What I would like to do now is re-assign the Workbook_Open sub to be set to null, so that it doesn't run any more. Is it possible to somehow assign Workbook_Open to call a null procedure, as opposed to setting up an onTime call to delete the code itself?

I have a standard module in which I gather information from a workbook, create an XML document, Post it, and collect the value I need from the response XML. Thing is I have to run through it maybe hundreds or thousands of times depending on the number of records I have. It takes ten years to finish the loop. I have read that it might be possible to post them concurrently using a class module and an event handler, but I have not worked with Class modules before. Compiling all the XML documents into memory is easy, posting them and getting my return values in a timely manner is the problem at hand.

to save typing the same things over and over I have created a dialog box with checkboxes, named with several common terms we use when writing an invoice. i.e. dig a hole, paint a fence etc. I have assigned the dialog box to a button on the worksheet.
When I check the checkboxes, I want the text to go to a blank section of the invoice one underneath the other. The reading I have done suggests this is an event-handler subroutine, I just don't know enough about VBA yet to be able to write the code.

I have a workbook with 20 worksheets the first is a summary called Discount Set the 19 sheets with various names
The 19 sheets in column H4:H40 u enter a number greater than 0 which is the quanty required. This is used to calculate a price on which ever row it is entered
the selection must only affect numbers as there are rows that are just shading and they contain no data .
So u could enter quanties on serval rows of different sheets to get a total price displayed in the Discount set
What I want to do is have button on the Discount Set which will clear any quantity that does not equal 0 back to 0 in column H which will reset the total 0.00

I know that a variable of string type is equal to "" before it's assigned a value. So I reset the value of strings to empty (i.e. "") when I want them clear of a value. I also know that variables of Variant Type are equal to NULL when they are unassigned so I reset them to NULL when I want to clear them of a value.
But what about a Long? When you declare a variable of Long Type or Int Type or Double Type, what is it's inital value when empty and unassigned. I assume it's not 0 since 0 is an actual number.
I want to reset my lng variable and clear it of a value. So I'm wondering what should I set to... How can i do this?

I have a textbox that pulls language using the following code:
Code:
Private Sub TextBox1_Enter()
TextBox1.Value = Sheets("Language").Range("B2").Value 'places the value of the cell into the textbox
[Code]....
Randomly and sporadically, when working in the textbox, the form seems to reset. By reset, I mean that the language resets to what was there originally.

When I execute a macro, and if during the macro execution I press the "Esc" key, the execution stops and I get a Microsoft Visual Basic window with the message that code execution has been interrupted with buttons to Continue, End, Debug and Help. If I click the "End" button, the window closes and Excel is at rest - which seems to be some sort of Reset process.
I have a need to execute that process while Excel is at rest.
Is there any way to code the process in VBA?

i have cells A1 to A10 filled with numbers
i have cells B1 to B10 blank
what i need to do is when something is typed in cell B1 - A1 to A5 are reset to zero and when i type something in cell B2 - A2 to A6 reset to zero.
I have tried to do this as a range ie
A1- A10 have numbers in B1 - B10 copy these numbers and reset if anything is typed in C1 with this formula =IF(C1:C5="",A1,"0") what it should do is reset B1 to zero if anything is typed in C1-C5 but only when something is typed in C1 does this work ..

I am not experienced at all with Excel, here is my problem: In column "A": I have 288 rows and has nothing but numbers in them. Row 1 is the lowest number, row 288 is the highest number. In each row the numbers typically increase; every once in a while the numbers may stay the same, but the number will never be lower. The numbers range from 0 through 600,000.
What I want to do is have column "B" follow column "A" until the cell total reaches 12000. The next cell in column "B" would then reset and start all over from "0". I want it to keep on reseting every 12000 counts. Another potential problem is that a majority of the time the cell value will not be an even 12000, 24000, 36000 etc. They may be more like A40: 11742 A41: 13201 etc.

My spreadsheet has 459 rows; however, the vertical scroll bar ends at row 569738. I have attempted to delete all of the extra rows by holding SHIFT and CTRL, striking the down arrow then right-clicking on the left margin of highlighted row numbers and choosing delete. I have also done the same procedure except clicking clear all from the editing menu. None of these methods has removed the rows and enlarged the vertical scroll bar to a proportionate size in relation to the number of rows.
