How do you draw a solid underline from one cell to another? I tried the last line below to do this but it only underlines each word. Is there a way to connect the line?
xlWSheet.Range("A" & i.ToString).Value = "Local"
xlWSheet.Range("B" & i.ToString).Value = "Name"
xlWSheet.Range("C" & i.ToString).Value = "Reg Hours"

I am using asp.net oledb to export information to excel file. I encounter problems when the information to export becomes too big, in this case the code I have given below, the excel file generated becomes an empty spreadsheet.If I changed the loop to 1123 for insertion of the rows. The generated excel file is fine, 1125 rows, and 4 columns shown.A test program in windows form is also working fine regardless of how many rows.[code]I couldn't find a solution to my problem as well. What I did eventually was to run the process using another separate windows service. The code works perfectly fine running from a windows form or service program, but not asp.net, not sure why.

View 7 RepliesI'm trying to upgrade a VB6 app to VB 2008. I have read the article in the tutors corner about automating Excel from VB but I cannot get it to work. Heres what I have done:
1) set a reference to the Microsoft Excel 12.0 Object Library
2) Added "Imports Excel = Microsoft.Office.Interop.Excel" to the top of the module
3) in a routine I have added: Dim X As New Excel.Application Here's where I get an error: Error 75 'Application' is ambiguous in the namespace 'Microsoft.Office.Interop.Excel'.
I'm working with vb.net 2008. My application generates 1 excel file (with login details etc). The application will store user results for various sections into csv files. I'm trying to combine the csv files into the excel file. I'm trying to get this to work with one csv file initially ...but I am ending up with a blank Excel file. This is what I've tried so far:
Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click

I have a project that has a need to display a Excel file in second window, but because other controls are needed, simply launching excel is not sufficient. Right now I do not know if the target machines have excel installed but I know with certainty that if they do it would be 2010, is there any method or library that allows you frame your own form around an excel window?
View 1 RepliesI have an application the contains several excel files bundled with it. I'm not opening the files and processing them within my application. These files contain a data-connection to reload all of the pivot-tables within each excel file. I have a 'link' on my form, that when clicked, it determines which file to open and calls a sub using filename and executing Process.Start(filename) for any excel file I want to open. I have no problems opening any one of the files and then exiting excel.
The problem is when I 'close' a file, but don't exit Excel; then try to open another file(clicking link on form)... it creates a new instance of Excel.
I know from experimenting that the fileopendialog form will 'reuse' an existing Excel instance, IF it does not already have a file open.
How can I do the same thing without using the fileopendialog?
I don't want the end-user to have access to the folders where these files live. That's why I have multiple 'links' on my form, one for each xls that already exists. I just want them to be able to click on a link and the xls file opens AND if they choose to merely 'close' a file and not exit... Don't create a new instance of Excel, but re-use the existing one.
I took oledbconnection with excel file, after disposing this connection i m still unable to open that excel manually,It shows some access error.
