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.

The problem is I am able to extract the data by giving cell reference like: TextBox1.Text = objWorksheet.Cells(5, 2).value
But I want to select a row as per input given by user and want to extract data from that row.
The input given by user is in text format, in my case name of employee. And I have to extract address of that name.

Well I had a thread going that branched out to this topic, so rather completely veering off the main topic there, I felt creating a new thread was adequate.So as the title says, I'm trying to create a user-defined type. It's not a simple type at that but a user here had showed me a way to fix all my problems. That was to create a type BigDecimal. Which my initial thought was to utilize the BigInteger type. Being that the Integer Part, and Fractional parts would be split off into two variables, both BigIntegers. Which would be combined at the end as a "decimal". However I have many many questions see that this is my first attempt at truly creating a type of my own. So as of right now I'm basically swinging in the dark here.

I have a project to import data from one worksheet into database SQL Server 2008 on Windows Server 2008 using Interop. The project in debug mode works fine, but accessing the site from a client computer, I am getting permission denied message to the file I'm trying to import and it is located on the server. I wonder what it takes to make additional settings, as well as file folder. IIS? DCOM?

With vb.net I would like to select 4 cells in Excel and then pass those cell values along with 1 button tag to a formula in Excel.I press a button with a month, say "May" as text. I want to grab a cell in Excel labeled "May1t" the value of which is the number of hours until may. This is the code I'm using.
xlsWB.Worksheets(2).Range(Month1 & "1t").Value I am able to set a variable with this as the value but,
I want to pass this cell (which will be updating as the time counts down) and 3 other similarly specified cells along with the button tag to an Excel formula.I have something like this:
Private Sub F_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles F.Click
xlsWB.Worksheets(4).Range("B2").Formula = "=MyFunction()"
xlsWB.Worksheets(1).Range(Month1 & "1t").Select()
End Sub
The formula takes the parameters in the order: MyFunction(Cell,Tag,Cell,Cell,Cell).

What I need to get done here is not a GUI, like the SQL Import and Export Wizard, which can be run from the SQL (2000) Enterprise Manager only, but a code that I can run from within the Visual Basic For Applications IDE from Microsoft Excel 2003, maybe in the form of a module, class or userform or a combination of all three. The best that I have come across so far, was a class that first checks if the worksheet is in a database formattable condition, then creates the database, if it does not exist, a table and then transfers the data from the worksheet to the table.
I have tried the Access 2003 TransferSpreadsheet method, but that does not solve my purpose, because I want to move the data from Excel to Access, starting from the creation of the database itself.

SQL Server has a Data Type of "Float". Visual Studio has a Data Type of "Decimal". In other words, if I have a variable in a VB.Net app that is defined as a "Decimal" ...can I move that value into a SQL Server Data Table column defined as a "Float"?

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 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

Within the application, I need to have two levels of access: Standard User and Power User,for example.These two levels can have the same access level within Windows.It is not my intention to elevate to administratoWhat is needed, is a way to have two different groups of users.ne group will be able to run the application while a second group has access to additional features within the application but not within the windows environment
It is my hope that there will be two user account types: 1) Standard User and 2) some other user type such as Power User or something else that will distinguish it from Standard User
