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
OK, 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.
Cells.Find(What:="flags", After:=ActiveCell, LookIn:=xlFormulas, LookAt _ :=xlWhole, SearchOrder:=xlByRows, SearchDirection:=xlNext, MatchCase:= _ False).Activate 'if there is an error, ignore it and continue On Error Resume Next Selection.EntireColumn.SpecialCells(xlCellTypeConstants, 1).EntireRow.Delete Shift:=xlUp 'reset normal error handling On Error GoTo 0
I am finding the cell marked "flags", then in that column look for the special cell and delete the rows where they are found. It works when it actually finds those cells, but it reports an error when no cells were found.
Is there a way to resume running a code should there be an incompatible file that causes an error? Currently I'm reading a bunch of excel sheets, but there might be some sheets that aren't formated as such and cause an error 400.
Using the code I got from the Forum Drop Down I added the subs to put a custom command button in the right menu. The first thing it does is delete any existence of the menu item so that you don't get a new one every time you right click your menu. I has just a clear as day "On Error Resume Next". But when it encounters the delete command the error dialog pops up and says "Run time error 5. Invalid procedure call or argument."
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:
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
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 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
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)
I have some code below. I have error handling in place for when it tries to open a specific file. If it isn't there then user has option to continue and ignore this file, or browse and select a new one.
The problem is, when the user wants to ignore the file, the "Resume Next" continues to run the VBA assuming the file was ok i.e. the code after the line to open the file. What I would like is for it to skip the succeeding code and go to look for the next file.
Below is the VBA:
Code: For i = 0 To 2 Step 1
'add in error handling for if the file is missing On Error GoTo MissingFile Workbooks.Open Filename:="\hbeu.adroot.hsbcdfsrootgb002hfcfinance01fnce" & qfolder & "Data" & qfile(i), UpdateLinks:=False, ReadOnly:=True
[Code] .........
Missing File:
qMissingPrompt = "There was an error opening data file. Click OK to browse or Cancel to ignore and move to next file" qAns = MsgBox(qMissingPrompt, vbOKCancel) 'click cancel - ignore error and move onto the next file If qAns = vbCancel Then
[Code] .......
So, where it says Resume Next, currently it will start running the following (after On Error Goto 0)
Code: Set datawb = ActiveWorkbook
range("A2").Select Do Until ActiveCell.Value = "" etc.
What I would like it to do is go back to is to go to the next i
Code: For i = 0 To 2 Step 1
Or even to go to the 'Next' statement at the end so that it moves onto the Next i and tries to open the next file.
I 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:
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.
I have a workbook with several hundred row the VBA code loops through. It takes about an hour to run all the calculations. Whenever I need to pause the script I hit ESC, which works well for me, but for other users it would be nice to have a command button that halts code. Even better would be another button to resume code.
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:
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?
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've got some code (at bottom) which works very well for small groups of data but when it gets large it hangs excel. Had heard that I can make code which will get it to pick up on the row after where it left off rather than having it run the entire loop again. Specifically speaking of the raw data sheet. It is sorted by date and by code so that if it works on the first code for the date it won't have to return to that row again for data. Uncertain how to implement that approach. (sample data layout below)
Option Explicit
Sub DoubleDirectionLoop()
Dim Wb As Excel.Workbook Dim Ws1 As Excel.Worksheet, Ws2 As Excel.Worksheet Dim iCol As Integer Dim iRow As Integer, iRow2 As Integer Dim Loop1 As Integer, Loop2 As Integer Dim Loop3 As Integer, PeakSum As Long
I use the following code to assign a macro to right arrow key.
Application.OnKey "{RIGHT}", "myMACRO"
My questin is how to let the right arrow key resume its normal function, that is move from left to right (A2 to A1) if I do not want the macro any more and without quit and restart EXCEL? The following code disabes the right arrow key's normal function. Application.OnKey "{RIGHT}", ""
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 want to create an event handler for multiple buttons. I know that it can be done in VB but I'm not sure about VBA. Auto Merged Post;bump* Auto Merged Post;bump*
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.
I'm trying to attach Worksheet_Change to a worksheet created at runtime. Usually you put it in the code window of the Sheet object but what do you do when you create the worksheet at runtime?
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.
