I have a SQL stored procedure that I bind to a Silverlight Datagrid. That works ok, the problem is when I use the same stored procedure to bind a different dataset to the same grid, it doesn't display the new data, only empty columns from the last dataset that was bound. What is going on here? I tried to set the grid = Nothing and I tried using Datagrid1.columns.clear() but that didn't work.

I have a dataset that is being generated from an XML file.
This dataset has two tables (User and UserSecurity) - that is related because they both have the same primary key. [i know, the tables should probably be combined, but this is the data that I have to work with][code]...

I am still having issues with the combo box. I have the correct query. I have four tables in MS Access. I need to create a form in Visual Basic that has a combo box and a datagrid. The selection from the combo box will display all relevant information about that person on the datagrid. For example, if I select John Doe (from the combo box) the datagrid should display: [Code] How do I add John Doe to the combo box and link this query to it, when upon being selected, it displays the result in the datagrid?

I finally got this code to work:
vb
Dim path As String = OpenFileDialog1.FileName
Dim myDataset As New DataSet()
Dim strConn = New OleDbConnection("Provider=Microsoft.ACE.Oledb.12.0;Data Source=" & path & ";Extended Properties=""Excel 12.0;HDR=YES;IMEX=1""")
Dim myData As New OleDb.OleDbDataAdapter("SELECT * FROM [Sheet1$]", strConn)
myData.Fill(myDataset)
DataGridView1.DataSource = myDataset.Tables(0).DefaultView
Now that I figured that out I was going to try and place the data in a specific location. On my application I have a datagridview set up with 4 columns. What I would like to do is put column A of the excel file under the 1st column of the datagridview and column C of the Excel File in the second column of the datagridview.
So replace:
vb
DataGridView1.DataSource = myDataset.Tables(0).DefaultView
With:
vb
DataGridView1.columns(0) = myDataset.Tables(0).columns(0)
DataGridView1.columns(1) = myDataset.Tables(0).columns(2)
Obviously this doesnt work, and something tells me I might need a for loop to import the data, but I have never imported information from an Excel file before and to make it worse I have never worked with datagridviews before so I have no idea how to go about this.
I would like to do something like this if I could:
vb
For x = 1 To xldoc.rows.length - 1
DataGridView1.Item(0, x).Value = CType(xlDoc.Cells(0, x + 1), Excel.Range).Text
Next

Major problems with the Schema. I am using the DataGrid and not the VB Express 2010 DataGridView. Using code to make a new DataSet and DataView. What is confusing me is when adding Items after right clicking the application in the Solution Explorer, the add items shows DataSet, Xml To Schema, and Xml File. It is obvious that I don't know how to generate an xsd file that I can read into a code generated DataSet. If someone is familiar with xml and VB Express2010. how to generate an xsd file using DataGrid instead of DataGridView that I can read into a code generated DataSet?

I have a search form on that will be pulling search template queries from a table in the underlying (an Access db on a share). The search form has a calendar control for filtering by date range, a listbox containing the names of the search templates, a second listbox which lists the fields in the selected template, and then some controls which show/hide themselves depending on which field is selected so that the user can pick a field and enter it's unique criteria in the appropriate control for filtering. Below these controls is a DataGrid, which will obviously display the results.
The problem is how to dynamically "transform" this DataGrid to display the selected search template. These templates do not represent tables in the underlying; rather they represent preconstructed SQL queries (stored in a table) which are essentially SELECT queries with joins and no WHERE clause (so they are the results of multiple tables joined together by their keys).
To be honest, I'm having trouble even generating the LINQ queries to represent these template dynamically, but that's not as important, since I can manually translate the SQL queries into LINQ. This is definitely not the preferred method, as the whole point of putting these templates in a table, rather than code, was to allow for future additions without rebuilding/redistributing the application interface.

I have a VB app and it has a login feature installed. Now when someone logs in into the app I want the users First Name and Last Name to be displayed on my second form where the user gets redirected on a sucesfull login. I don't know how to accomplish this as I am quite new to VB. I have provided my login code below (btw it uses an online database):
MySqlConnection = New MySqlConnection
MySqlConnection.ConnectionString = "server=;Port=; user id=; password=; database="
MySqlConnection.Open()
[Code].....
I think the code which provides the first name and last name need to check the users username which was provided on the first form and search through the DB. Then when it has found the record it should recieve the First Name and Last name.

I understand how you can expose data in a database (with access to mysql) in Odate in order to create a program in VB.NET and connect to these data with a service.
the purpose of all this is to create a software to display data, and dynamically modify the data remotely.
