Setting Loop Counter=number Of Worksheets In Any Workbook?
Jun 18, 2009
I want to write an Excel macro to set print formats in all worksheets in a workbook. I don't think you can do this by grouping; it appears you have to do it in each individual worksheet. I want to be able to run a macro in any workbook to loop through all worksheets in the workbook and then select the first worksheet.
How do you have the macro determine how many worksheets there are and set the loop counter equal to that number?
I'm trying to delete all the worksheets contained in a workbook using the code below but I get this error:
"Attempting to call into managed code without transitioning out first. Do not attempt to run managed code inside low-level native extensibility points, such as the vectored exception handler, since doing so can cause corruption and data loss."
For Each obj In xlWorkBook.Worksheets xlWorkBook.Worksheets(obj.Name).delete() Next
I tried to do this a different way yesterday and it told me I couldn't have a workbook with no worksheets. Is this written in stone or can it be done?
I have 2 workbooks( Book1 and Book2) with multiple sheets.I am only interested in one of the worksheets in the workbooks(both the worksheets names are the same).The thing is that the data is in the form of pivot tables, so each time i have to filter according to specific categories, copy and paste into another new workbook.The thing is column headings in both the worksheets are different,BUT BOTH the worksheets data must be combined into 1 single worksheet( row after row).
Meaning in Book1, my columns are in the form of Cost, revenue,margin and in book2, the columns are in the form of Cost,Revenue, Profit Margin %.... That means i must add a profit margin % column in Book1 and a Margin column in Book2 before I combine the data into a single worksheet. Each week, new data gets added into Book1 and Book2, so I wish to automate this by creating a code, so that when the source data changes, my new workbook's data also changes.
My program needs to convert the variables users enter in textboxes from metric to imperial and vice versa so the user can switch units at any time during run time and have the values in the textboxes display the correct value. The problem is that for example if the user initially enters all his values in metric when converting I will be displaying the rounded value of the imperial value. If the user initially enters his values in imperial, when converting I will be displaying the rounded value of the metric value.
But the problem occurs when then user switches back to the original units all the values go to 0 because in the coding for my radio button I set the txtboxes to the rounded xxx value. How to code the radiobuttons to detect what unit was initially selected to set the right values. What I tried doing was set a counter on the radio buttons to determine which one has been pressed more often... but there has got to be a better way to do this..
Imperial Radio button: Private Sub optImperial_CheckedChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles optImperial.CheckedChanged 'Change Labels to Imperial lblMDegreeC.Text = "Degree F" lblMDegreeC2.Text = "Degree F" [Code] .....
i wanted to know how to create a for...loop...and specify the counter for the loop to control the animation time. I want the for..loop to increase the speed of the moving object (button) and move it 5 times...
the code i started with is
Private Sub ForNextButton_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles xForNextButton.Click For Counter = 0 To 1000 'do somtething----the something i want to do is repeat the moving process 4 times and at a fast speed---how do i write that Next
I have a sub which requires multiple counter variables. Is there a more efficient way of doing this. My example is simple. Image if I had 20 separate counters I was trying to manage. I would have to create 20 separate variables and then increment each in the desired place in the code.
Dim Counter1 as Double Dim Counter2 as Double Dim Counter3 as Double
I'm trying to load a file where this file has, like, 10 lines. And I want to load each line (0 to 9) to each TextBox in my app (TextBox1 until TextBox10). So, there's a way to do this with a counter?
Like this mine code (that doesn't works): If (System.IO.File.Exists("configs.ini")) Then Dim configs As String() = System.IO.File.ReadAllText("configs.ini").Split(vbNewLine) Const Max As Integer = 9 Dim TextBoxes(Max) As TextBox For i = 0 To Max TextBoxes(i + 1).Text = configs(i) Next End If
I have a for loop which goes like this - for i = 0 as integer to 100 result &= "Name" & sqldr("name") result &= "Lastname" & sqldr("lastname") result &= "dob" & sqldr("dob") next
The sqldr is the sql datareader (not important here) I want my end result to be Name1 = Sam Lastname1 = Davis dob1 = 01/01/1966 Name2 = ... Name3 = And so on depending on how manyrecords are in database. How do I make this happen in this for loop?
The program is to take an entered string then search for a subset of letters entered through and input box.In my subprocedure Sub btnSearch_Click I am using a loop to move through the entire length of an entered string to search for a set of letters entered through an input box. I can find the set of letters to search for but instead of increasing my counter "Found" for every instance of a match it returns the length of the string instead. I just don't know why the IF doesn't prevent the counter from increasing for every element in the string. I want the counter to increase only when the match is found. I just put 2 message boxes in there to make sure it found the right letter and then display the counter.

We have a project that needs to gather survey data. On one particular page of the website, there are 21 questions each with a scale of 1-5 where the user selects one radio button for each question in the table. The survey is being coded in VB.NET. The data submits to an SQL database. All the radio buttons are similarly named, so only the number changes for the question [Code]
Im writing a program and its pulling data from a .MDB to put in a .DAT file.
Here is my while loop:
vb database_connection() sql = "SELECT * FROM tlalist"
[Code].....
In my database there are currently 6 rows. and only 1 row has the TLA_DAY column equal to 1, but for some reason when I look at the .DAT file it creates it outputs the result twice rather than only once.
Once JTLA_count increments it becomes "2", but the while loop still outputs as if its still equal to "1". Ive used breakpoints and the counter is incrementing fine.
In building an Excel workbook with VB.Net, is it possible to sort all the worksheet tabs into a particular order? I'm building a workbook with individual sheets named by drive letter, i.e., "C Drive", "D Drive", etc.
I kinda found a way to get the name.. but not the value.. anyone have some sample code to just run thought the settings and spit out the name and value ?
I am trying to write a small program that will beep every two minutes as a gag for a friend of mine to play as a pratical joke on someone however when I run it I get this error message "TimeSpan overflowed because the duration is too long." and I am not sure as to why I am getting the error message.
Basically what i am doing is clicking on a picture in a Picture box and posting a label to the spot i click on. in some instances i will need to put as many as 60 labels on an individual picture. Below is a snippet of code that works perfectly fine to place 1 point. What i would like to do is setup an array of labels. Something along the lines of
[Code]...
then be able to loop through the code below until i get all my labels placed. The only issue is that when i try doing that i get an error that Label is a type and cannot be used as an expression. Is there another way to do this that i am not seeing?
I'm looking for some code that uses progressively smaller steps that will converge 2 numbers to a tolerance of 0.00001. The starting difference between 2 numbers may be as high as 100 so using a step value of 0.000001 is not a good choice to start with. I thought about nested DO:LOOPs or a nested FOR:NEXTs but think there must be an easier way to achieve this. Has anyone coded a convergence loop like this?
I have this code sample from a book I'm reading which looks to be incorrect:
Imports System.Diagnostics Sub Main Dim pc As New PerformanceCounter("PerfApp", "Clicks", False) 'excepiton here pc.Increment() counterLabel.Content = pc.NextValue().ToString() End Sub
There excepion message I get is: The requested Performance Counter is not a custom counter, it has to be initialized as ReadOnly. I looked for a property to see if I can set it but couldn't find one.
I have 15 checkboxes of control array and at run time fill any 4 or 5 or 6 check boxes with color using colordialog. How can i send the colors to the sql server table using for loop using code at runtime
I want to make a autotyper and I was wondering how would I make The words I am writing in the textbox be set to a number of times? EX.- say I want to write a word only 10 times instead of it keep repeating..
I dont want to be setting the index positions and lenghth to a specific number becuase when i choose a different name from the listbox that is at a different position or longer it wont display it properly. explain to me another way around this so as it will allow any details to be selected and read???
So i am trying to add new worksheets to excel...not a problem there, but then I had a thought: What I really need is the proper code to add new worksheets on open that are named all of the dates in the current month minus saturday and sunday dates. That is what started to throw me for a loop. so i started with
set newsheet = worksheets.add newsheet.name = date $
I'm trying to get the first row in each worksheet to be shaded and have the font bold. Right now, I am able to get the first worksheet changes made, but none of the other worksheets within the same workbook are being changed. Here is what I have written so far for creating the spreadsheet and applying a format.Public Function WRITE_TO_EXCEL(ByVal dt As System.Data.DataTable, ByVal includeheader As Boolean, ByVal worksheet_index As Integer) As Integer
Is it possible to manipulate data in worksheets?[code]...
what i want to do is round off the time in if the time is greater than 6:00 example please look at the data date 8/2 and 8/3. i would like to modify it and make the 6:01 to 6:15, and 6:16 to 6:30 , every 1-15min late the time would round off to the nearest 15mins.. my question is how can i make loop in the column "time in" and every time the program sees a "late IN" it will round it up to the nearest 15mins.
I have a bunch of Excel workbooks that contain multiple worksheets. I want to loop through each workbook and export each worksheet into it's own new workbook. I want one worksheet in each new workbook.
Here's what I've got so far: Sub ExportWorksheet(ByVal worksheet As Excel.Worksheet, ByVal filePath As String) Dim xlApp As Excel.Application = New Excel.ApplicationClass Dim xlWorkBook As Excel.Workbook = xlApp.Workbooks.Add worksheet.Select() worksheet.Copy() [Code] .....
