I've been putzing around with this for awhile but I need to delete column B (minus the header) when ever it is empty.
If xlWorkSheet.Range("B2:B65565").Value = "" Then
Dim rg As Excel.Range = xlWorkSheet.Columns("B")
rg.Select()
rg.Delete()
End If
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.

View 1 RepliesI found out there are ways to Select, Insert, and Update Excel file by using OLEDB. But the limitation is that we can not delete a record.My idea is to delete row (instead of record). The question is how to programmatically delete row in excel, by id selected?I want to delete the row where id = 3. I can grab the id, but have no idea how to delete the row which contains the id 3.
View 3 RepliesI'm reading data from Excel and processing the file line by line.
If the process succeeds then I need to delete that row from Excel and save it. If it fails, then continue with the next line and so on.
Initially I used OLEDB to read data from Excel, but by using this I cannot delete rows.
I think we can solve this by using COM component.

The Strange thing is that Microsoft API reference says that it would produce a Boolean, but it doesn't as it is a Sub and not a function.
I am trying to create a .Net application to edit a excel file by deleting some columns and keeping the columns which we need and then removing the duplicate values based on the first column which is going to be the Serial no. which should have a check to have 6 digits by default like 2563 should be displayed as 002563.

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:

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 strSourceFolder As String

View 1 RepliesI 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.

How to pass values to a particular column in Excel
View 8 RepliesI 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
