I need to read data from an Excel sheet as part of a data conversion. Certain columns contain mostly numeric data but may contain some alphanumeric data somewhere in the excel sheet. The problem is, my conversion sees the alphanumeric values as null (or blank. Using the .ToString() method returns ""). To connect to Excel, I'm creating an oledb connection, creating an OleDbDataAdapter, then filling a DataSet with the adapter.
Here's the VB code for connecting:
private _oleadpt As OleDbDataAdapter
private _oleconnection As New OleDbConnection
Dim olecomm As OleDbCommand
'_database comes from a settings file and is the full path to an excel document
Dim connstring As String = "Provider=Microsoft.Jet.OLEDB.4.0; Data Source=" & _database & ";
Extended Properties=""Excel 8.0;HDR=YES;"""
[Code] .....
I think the data adapter is determining the datatype for the columns based on the first however-many rows it looks at. It decides the columns with numbers are numeric which is the start of my problem. Changing the formatting of the column in Excel doesn't seem to affect the datatypes in my data set. Is there a way to tell the dataadapter or dataset what type of data to use for a column? Or should I try to cast the data in my SQL statement?
I'm creating an application that will be visiting several different sites.Each site will have the same elements but not necessarily in the same order.On a previous post I was told to use the Select Case to choose between the choices.Can Select Case be used to choose between Webpage elements?Let's say that on one site the first web page element is choose button A but on site two it will choose button B.

This may or may not need to be moved to the deployment folder...Okay I have a vb.Net application that connections to a sql server 2005 database "TacticalDB" while debugging the application I was using the connection string,
Dim con As SqlConnection = New SqlConnection("Data Source=.SQLEXPRESS; AttachDbFilename=" + Application.StartupPath + "DataTacticalDB.mdf; Database=TacticalDB; Trusted_Connection=True; User Instance=true")
Which works fine, but I have moved into getting the application ready for deployment and so I created a setup application in the same solution as the application. Now I have added the database file with the setup but when my application gets to the con.Open() line it catches an exception,
System.Data.SqlClient.SqlException: Database 'C:UsersJohnDocumentsVisual Studio 2008ProjectsBlackout_ScoutBlackout_Scoutinx86DebugDataTacticalDB.mdf' already exists. Choose a different database name.
Cannot attach the file 'C:Program Files (x86)MicrosoftSetup1DataTacticalDB.mdf' as database 'TacticalDB'.

Now I only have the one place where the application should look for the Database and thats Application.startupPath/Data/TacticalDB.mdf and if im running the newly installed exe it shouldn't look back in the myprojects folder but it is.

View 3 RepliesI am working to a big solution that is almost finished. The language interface is Romanian. Now I have a problem because I have to make an option at login in which user can chose the language - and I have to create all the software in Romanian and English languagesd.
My intention is to create inside of o database (because my application is working with an sql database) a table named lang_tbl and in which I will put all the words and text that I have used in the application in romanian on one columnb and in English on another column and when I start the application I will load all the rows from the table in an array together with the unique ID's. And in runtime I will use the unique ID for every text that I have in the application.
I am quite new to the VB scene, and am still quite confused by the variety of options presented as far as choosing the correct project type.I have been coding for roughly 4 years now and consider myself still to be a beginner. My past experiences include, hmtl, C++, vba, assembly, and a few others which I'm sure currently escape me.However, VB is a whole new boat and I'm just not sure where to get started with what I want to do.I've Googled the internet, went through the MSDN, and even did some tutorials.My current dilemma is I wish to make a program that will do a the following: Allow a User to download a set of data from an embedded web page.Open an excel file Download more data from a different web page.Open another excel document..I'm sure this is probably quite simple to do (read: I hope...). However I'm just not sure where to begin as far as choosing a project type. Additionally I'd like to have it set up with buttons, where button1 reads something along the lines of "Step 1: Click Here to Go and Download Data", "Step 2: Click Here to browse to excel file", etc etc.What type of project do I chose to get the stuff done on my list?

View 2 Repliesin VB.NET DGVedit mode, after press ENTER to move the active cell into the desired cell, notdirectly move to the next line, how is it?
View 2 RepliesThe problem is that if you never enter anything into a cell for a new row then that cell is never validated. This is a problem because I have columns that should not be null. I am doing the check in the row level validation and storing the information about which cells are empty that should not be empty. The row level validation works fine and the row level validation error indicator goes on,(red exclamation mark at the beginning of the row) but I also need a visual indicator on the individual cells that are in error.
I am thinking that setting the HasError property for the cells that are in error should cause them to display n error style (the default red border). Is there a way to this this either from XAML (perferably) or from code?Alternatively I could cause those cells to re-validate when the row editing is finished. Does anyone know how to do this?

I'm attempting to copy cells, one at a time, from an Excel 2003 (or 2007) spreadsheet to a Word 2003 (or 2007) table. I'd like the code to be version-agnostic, and so am using late binding. The formatting of the contents of the Excel cell, such as color, underline, strike-through, needs to be preserved. My approach is to use a Word doc as a template. It has a table at the top which I can copy to the end of the doc, add rows as needed, and fill in the word table cells with the data from the excel spreadsheet. Unfortunately, all the formatting disappears. All I get is the text itself.

I wanted to implement the use of Enter key when entering data and moving from cell to cell. How am i going to implement that?

I have a DataGridView with several columns. One column is a TextBox column named "Status". This column can only show one of three values: 'Final', 'Ready', or 'No Reportable'. I want to have some code that would turn the TextBox cell into a ComboBox cell when the user left-clicks on the cell to allow the user to choose one of these three options. When the user clicks elsewhere or the cell loses focus I want the cell to change back to a TextBox cell.
Here is what I have so far, but the code throws an exception indicated below Plus, I don't think the code would remove the combobox when the cell loses focus.
Exception: "Provided cell does not belong to this DataGridView control."

View 4 RepliesI have a datagrid that will be accepting data from an external measuring device via the serial port. The grid is also open to editing records as well. Part of the process of making this grid user friendly is to intercept the "enter" key and move to the next cell until there is a value in the cell. This is only for some cells, other cells can be blank. I have worked out how to intercept the "enter" key from another post on this forum. Here is the code:

I'm using something call ultragrid in my program.The program works as a mini-record keeping area (Like any datagrid, really).
