I created a VBA project in Excel. I would like to figure out how to transfer the data back in forth to make a more presentable and user-friendly program in VB Studio.Basically, I need my form in VB to input data to into an excel �workbook.data�, where the calculations are preformed. Then I need to copy the finished excel data cells �workbook.results� and paste them into an end result form in VB. I have tried looking at threads and cannot come up with a solution. There is no data saved each time the program runs, so I don't have a database.

I would like to prompt the user, in the middle of a VB program, either with MsgBox or any other dialog, to input data in a worksheet of the Workbook that contains the code and then, on some event, read the data and continue execution.

I have a bunch of Excel files, each file with multiple worksheets (aka, tabs). I want to loop thru each file, and within each file, loop thru its worksheets and do some stuff. I've included Microsoft.Office.Interop in my code and I am able to do Excel operations but I am not sure how you loop thru the multiple worksheets within a workbook.

I know I havent posted in awhile but you guys have done such a good helping me, my projects have been a breeze lately I have a new challenge though and I cant seem to figure out the solution. This new project Im working on sends a range of cells from an excel worksheet to the body of an email message and attaches two files.
I already have the automation down for the population of the excel file.I just need to copy Range A1:F20 from xlsheet3 to the body of a blank email with a populated subject line.Ive checked out this site already [URL].. but he seems to be accomplishing it with excel where as I (if I can) would like to do it in VB on VS .
My application searches for a specific worksheet in an open workbook. The code to find the worksheet is:
If Amendaction = True Then If oBook IsNot Nothing Then
For Each ws As Excel.Worksheet In oBook.Sheets
If ws.Name = SheetToFetch Then SheetFind = ws.Name
[code]....
When I execute the code, depending on the worksheet name, the result found in ws.name has one or more spaces in front of the text. e.g. "Bour001" used in creating the worksheet name becomes " Bour001" when returned by ws.name.
I have been asked to create import functionality in my application. I am getting an excel worksheet as input. The worksheet has column headers followed by data. The users want to simply select an xls file from their system, click upload and the tool deletes the table in the database and adds this new data.
I thought the best way would be too bring the data into a datatable object and do a foeach for every row in the datatable insert row by row into the db.
I want to read an excel file using VB.NET program. I know the logic below can do this. But I have a question. What if I don't know the name of the worksheet OR if the name of the worksheet is not SHEET1?
