How to fill a TreeView from two related tables (Customers 1 -> Products n)? I have seen the example of microsoft using Northwin Database and I do not understand this, I need something simpler.

I am trying to make a database, fill it with tables and then fill the tables. I am having problems connecting to the server and am really not sure why. I have posted this thread in two areas of this site because I was not sure what was the best area to put it in. [code]
View 3 RepliesI have an Access 2003 DB and an SQL Server 2005 DB.
I have one datagridview where I want to present data from both databases.
My query would look like this:
SELECT
ACCESS2003.Resource_ID,
ACCESS2003.NAME,
SQL2005.Resource_ID
[Code]....
SQL statements:
SQL = "SHOW TABLES;"
Try
conn.Open()
The remarked area works fine when I'm accessing a specific table. I've successfully inserted the products_model field into the combobox too. The datagridview does show the table names in the db using the SHOW TABLES sql statment, but I'm not understanding how to get this info into the combobox instead.
I'm looking for a recursive subroutine.I have the dataset from sql-server with in the datasource-table a parent- and a child-column.
I made a routine to put the parent-nodes in the tree.The problem starts with the childs over so many levels.I can write it out but it is to much code, I'm sure it can be done more efficient with a recursive subroutine.
.tv_Ana.Nodes(A).Nodes(B).Nodes(C).Nodes(D).Nodes(E).Nodes(F).Nodes(G).Nodes(H).Nodes.Add(Trim(sLev_nI + "-" + row_nI("MidCod").ToString()))
The tree will be about 25 levels deep.A few days ago I saw a recursive subroutine to fill the childnodes without the above difficulty to write alle the levels in code.That example I cannot find it any more, but it had a line of code more or less like this here below:
Dim
Nodes As TreeNodeCollection = tv.Nodes(A).Nodes
but it doesn't work yet!
I have a database with values as shown in the attached image "Image1.jpg". There are multiple other columns not shown on the screenshot (over 30), for the sake of this question we'll say I'm interested in columns called "Col1", "Col2", "Col3" & "Col4".
I was able to get this information automatically filled into a TreeView as shown on attached image "Image2.jpg".
At this point I also want to fill a DataGridView from the same database.
I managed to accomplish this with the following
Private Sub FillDataGrid()
Dim DA As New OleDbDataAdapter
Dim DS As New DataSet
[Code]....
But unfortunately this uses the manual binding of data to the DataGridView, which I'm sorry to say I struggled to "convert" if you like, to using SQL commands and coding to connect a database to DataGridView.

I need to fill a datatable(in data set) row by row by providing the the data by variables in VB.Net.

View 3 RepliesI have a SQL Server database for which I have created a strongly-typed DataSet (using the DataSet Designer in Visual Studio 2008), so all the adapters and select commands and whatnot were created for me by the wizard.
It's a small database with largely static data, so I would like to pull the contents of this DB in its entirety into my application at startup, and then grab individual pieces of data as needed using LINQ. Rather than hard-code each adapter Fill call, I would like to see if there is a way to automate this (possibly via Reflection). [code]...

I'm very new to asp.net and I have a general question about datalists. I was able to get this to work, but I don't understand how really. I think I need someone to give me the "theory" on this. So first I connect to the database:

Here are my questions:
- Why is the datalist pulling field2 successfully?
- Are the MyCommand.Fill(DS, "field1") and DS.Tables("field1").DefaultView meaningless?
- I guess my bottom-line question is, why do I have to specify fields in the vb if I can output any field?

I have a program that will load a web page into the Program Contained 'Webbrowser1' and autocomplete the Login by referencing the Code:
WebBrowser1.Document.GetElementById( _
"frmLogin:strCustomerLogin_userID").SetAttribute("Value",

What I actually want to do is directly enter the Value into the Active Browser page, rather than the program contained 'Webbrowser1'. What code do I need to access the Current Browser Web page (be it IE, FireFox etc)?
this is the code in the webpage:

I am working on a database application. I had used Dataset to link my VB programme to a database and selected specific tables. However, I created more tables in the database and I wanted to add the new tables to the dataset. I could not find a simple way to do this, so I deleted the existing dataset and created a new one. This move has broken my VB codes. I can no longer run them as errors are shooting up. In fact, I connot view the forms in my programme anymore. I have a backup of the codes to rerun, but then I need to add new tables to the dataset.
