Excel Column Deleting Program?
May 27, 2010
I have a server that exports a file to our server every wed and sat. The file is a .csv file, so I created a batch file to move that to a folder and rename it to .xls. My problem is that there are things on that excel file that that the dealership doesn't want, like a cost column and some other blank ones i need to delete. So I want to write a program that will read that file into the program, delete the columns, and then write it back to file. So when they go into the excel file those columns won't be there. So i have to do this to 3 different ones because there are 3 different dealerships. So far this is what I have. I would like to create this on a Console App, because I want to be able to just run this from the dos prompt, or I think I'm just going to have a schedule run it for me at a specific time on wed and sat. But this was created in the Forms App
This is what i have:
Imports System.Object
Imports Microsoft.Office.Interop

I've made a dataset using the dataset designer, and I'm trying to add a column to reflect changes made to the database (added a column, nothing fancy). Is there a way to 'refresh' the dataset schema from the datasource without deleting my adapter (and all the methods and queries I've created)?

I have to compare two columns in two different Excel sheets and delete the duplicates. I have come up with several strategies that work, but I am searching for the most efficient way to do this. At first, I was sorting the columns and looping through them in the manner of a sequential update and deleting when the cell values were equal. But I discovered here an article by Mike Rosenblum that explained that it is much more efficient to stick the columns into an array and iterate them from there. So I was able to do that. There was a complication in that once I had deleted a row, then the array and the spreadsheet were out of sync. So I had to compensate by incrementing a variable each time a row was deleted, and subtracting this variable from the array index to calculate the row to be deleted in the spreadsheet.
So now I am wondering whether there is a better strategy. I thought that if I could merely hide the rows to be deleted and then find a way to delete all hidden rows at once after the loop was over, then this would eliminate the problem of the array and the spreadsheet getting out of sync and would make the code easier to understand. I thought of putting the row numbers of the duplicates into another array and deleting the rows after the comparing loop. But this creates the same problem of having to compensate the row numbers in the array.

I am writing a program that loops through all of the sheets in an Excel workbook and saves each sheet as its own workbook. It turned out to be a bit trickier than I expected, since the Sheet.Copy method creates a strange object (see here for the MSDN discussion that I believe is relevant: [URL]. Anyway, I found a Stack Overflow post [URL] that got me to where I am, which is essentially complete, outside of one hanging EXCEL.EXE process that is left after the program completes, which I believe is a result of the sheet.copy method creating a new workbook (potentially a new application as well?). The other thing I run into, which I believe is related to this, is that even though I have my application set to visibility off, when I run the program, excel still opens up and is visible going through the steps.
Here is my code:
Code:
Imports System.Data
Imports System.IO
Imports Microsoft.Office.Interop
[CODE]...
Now I think the problem comes from the end of the loop, where I try to close the export file and the new worksheet it creates:
Code:
'close excel and release com objects
System.Runtime.InteropServices.Marshal.ReleaseComObject(exportsheet)
exportsheet = Nothing
xlApp1.Workbooks(fileNames(counter - 1)).Close(False)
I can't figure out what to do to release the `ComObject` for the new worksheet that is created. I have been trying all sorts of things, but it always throws a COM error when I do it and if I try to define it as nothing (like I do with exportsheet) is says that it is read only by default, so I can't do it. It seems like it should be something as simple as: System.Runtime.InteropServices.Marshal.ReleaseComObject(xlApp1.Workboo ks(fileNames(counter - 1))) But that is not the case. I have tried a few variants of this and I am thinking it has to do with the MSDN link above, but I can't quite sort out what to do. So the code works for my purposes, outside of leaving one EXCEL.EXE after it is done. As far as a test file, I am just using an Excel file with 3 sheets and I put some information on each and change the sheet name, so it is easy to see if it is working or not.

Final Update: On the off chance that some poor soul ran into the same issue I was running into, the first update should solve it, but it is also important to note that the excel.exe will hang until you close the application. I am report automation code as a windows form application (so coworkers can give the file location and such) and there is going to be an excel.exe process running until you close the pop up window from the program. Maybe garbage collect does not run until you close the application window or it just hangs on to an instance of excel.exe for some other reason.

I am reading an Excel file into VB.NET. There are 4 columns containing dollar figures of varying amounts. Here is what I need to do is identify the columns with the highest $ figure, the next highest, etc. and mark them so that .NET can identify them (e.g. col3 is highest so rank1 variable is "col3" and so on).So I am dealing with Excel Ojects which is new to me and sorting which is new to me. If it helps, here is how I am reading in the Excel file:
xlsWorkBook = xlsApp.Workbooks.Open(folders(f).ToString & "" & fileInFolder.ToString)
xlsWorkSheet = xlsWorkBook.Worksheets("Sheet1")
Dim ColumnNumber As Integer = xlsWorkSheet.Cells(1, StartColumn).Column

I have many files at work that need to be copied from one directory to another. However, I do not need to copy all the files at once.
I get excel sheets with the list of files that need to be copied once a week. So, in the main directory there is about 150.000 files and I only need to copy about 800 at a time.
I am thinking of having a textbox and an open dialog so I can pick the directory the main files are at - another one where I can choose where they will be copied to.
The problem is the list will be in excel sheet (column A). How do I have vb.net (2008) see the file names in column A and find them and move them?
Right now, I have macros in excel doing the job, however, I have so many things in this excel I need to transfer this part out and into vb.net.
The macro in excel doing the job is:
Code:
Sub CopyFiles()
Dim objFSO As FileSystemObject
Dim strSourceFolder As String

Looking at deleting columns in excel and have found several threads that show how to delete an entire column which I have tested and done successfully. These columns were all identified by "A", "B", "C" and so on...
I was wondering if it was possible to do the same thing using the column headers. When deleting the columns in excel, one has to keep in mind that columns deleted from the left will shift the entire sheet to the left and if one is not careful, the next column[code]...
Let's say a user wants to delete the 'Middle' column (assume as column B in excel) and then delete the 'Suffix' column (assums as column D in excel). If they don't know to work from right to left when deleting columns, they would write code that would delete Column B and then repeat that code for Column D. However, once column B is deleted, all columns will shift left, which will result in the 'Phone' column (formerly column E now column D) being deleted instead of the 'Suffix' column (formerly column D now column C).
If there was a way to delete the columns by their headers (i.e. Middle, Suffix...) this would eliminate the problem; to me it seems a bit more intuitive as well.

How to pass values to a particular column in Excel

Dec 2, 2009
I have a function within a class that imports an Excel sheet into an arraylist. I have overcome the problem of asking the user if there is a header or not. Now I want to ask the user which column is the data in. Here is my basic code for getting the header Yes/No and this is handled with a simple MessageBox... but of course this cannot be used to return a numeric value such as (0) being column #1. So I'm thinking I need a special form to pop up which the user will enter the the column being 1,2,3,4,5... etc. Of course subtracting "one" 1-1=0 is column 1 and 2-1=1 is column 2, etc.
Here's how I handled the header issue with a message box:
Private Sub ValidateCriteria()
If m_header = "" Then
GetHeader()
If m_header = "" Then Throw New Exception("Do you want to specify header row before importing?")
End If

I have a range in excel and I want to be able to sort it by one column programmatically.
There is range.sort, but it has a ridiculous about of parameters and I cannot get it to work.
Surely there must be something to be able say I want this data to be sorted by this column?

I am using VB.NET to query via SQL an Excel spreadsheet using ADO. The general way is like this: SELECT [firstname], [secondname] FROM [Sheet1$] Which works perfectly
However, one of the headings is called 3, so I want to do: SELECT [firstname], [secondname], [3] FROM [Sheet1$] However, this does not work. I know I can use * to get all columns, but later on I want to use (using dataReader): dr("3") which won't work

I want to calculate the difference between 1st Value (B2) and last Value (last populated row in column B)
Edited :
Using formula : =B2-B6 is not what's required. (I want diff in Cell C2)
I want when the user enters the value in B7 it automatically shows the difference between B2 and B7, when he populates B8 then it shows the diff between B2 and B8 and so on.. I don't want some direct method to do this in Excel and not by iterating all values to check the last value.
