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'm trying to code a button which has a SELECT statement to get information from one table but I want the information displayed in a data grid view.From the data grid view, this data will be stored in a different table within the same database.Previously i had used a list box to display the information but i could not save it in the data base.[code]Is there any way you can display this on a data grid view like i did on the listbox?Im using a datagrid view textboxcolumn column.
The application I'm working on requires that I print out some tables without having a datagrid present.Is there a way to print the tables to a printer using the PrintDocument object or does have to be done another way?

So I've been playing around with SQL strings in VB 2008, and trying to retrieve records from a database and display them in a data grid view. This is the part of the code that gets the fields and displays them in the data grid view:
None of the Microsoft videos I have watched, or the other posts I have seen, have given me the pieces I need to understand this process. This is the one key piece of understanding that I need to finish about 4 different programs I have started in the last 2 years. All of them key on understanding the following processes:
I created a table in Excel using excel 2007's Table feature, with the numbers 1 - 5 in one column, and a number of food products in the second column, easy enough, but now i have to display that table with it's gridlines, in VB2008, how do i do this? 2nd question I created a textbox in Visual basics, how do i tell it to display the value of, lets say Cell B5 from my excel file?
I have a SQL Data Base. I have created a relation between these tables. Problem is when i drag and drop it on Data grid i get only Parent table columns but i want to sea them both like this.
My aim is to choose a value from Listbox1 and on Listbox2 I would like to display the corresponding value from a table in my database. I mean, when I select Product A from Listbox1 (which is getting its values from row "Model" in my database table), I should see its price on Listbox2 which is available in the "Price" row of the same table (and also manipulate this price in different places for calculation etc.) . I am not sure if the best way is using "databinding.filter".
Here is the code I have but I cannot making it work:
Dim dtCOP As New AmetailorDataSet.COPDataTable Dim adapterCOP As New AmetailorDataSetTableAdapters.COPTableAdapter adapterCOP.Fill(dtCOP)
[code]...
A small note: my aim was using a Richtextbox instead of Listbox but I am told that Richtextbox is not suitable for using with datasources.
I am trying to display in my richtextbox1 a text from a table in my database according to some conditions that I decide by filtering. I worte a code for this but I think I am making a mistake because it gives errors all the time with Richtextbox (it does not accept datasource). Could you please help me on this?
Here is the code I have:
Dim dtCOP As New AmetailorDataSet.COPDataTable Dim adapterCOP As New AmetailorDataSetTableAdapters.COPTableAdapter adapterCOP.Fill(dtCOP)
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 currently have this working already for one of my combo box's, but when i try to use the same code i get this error ''There is no row at position 6.'' . The are 2 fields in the table asset_type_id, asset_type_name', im trying to dispaly the values in a combo box for the field 'asset_type_name.
the code for ' Friend Sub RetrieveCustomerInformation2()' works but the other friend sub throws the error. Imports System.Data.SqlClient Imports System.Data Imports System Imports System.Data.OleDb
i have to create a mortgage calculator (I know we have killed this mortgage calculator). Has to display an amortization table to display the list after doing the calculation. Here is the actual assignment:
Write the program in VB.Net (not Web based) and have it accept user input of the amount, term and interest rate. Display the mortgage payment amount. Then, list the loan balance and interest paid for each payment over the term of the loan. The list will be longer than the screen, so use loops to display a partial list, hesitate, and then display more of the list. Insert comments to document the program.
I have created 4 buttons. Calculate, Clear, List, and Exit. The buttons all work, but the list does not. Not sure what i am doing wrong.
I am trying to update a database table from my datagrid using an event handler and ItemCommand. I manage to call the routine and everything is working fine except the text that is inserted into my database is empty. I managed to track this back to the text not being passed from my datagrids footer to the sql parameters. I tried using a string first and then passing that to the parameters but they were also empty. I am accessing the control using the following line.
is there a way to caputre the values in a datagrid and bind them to a sql table? I have a datagrid bound to a sql query with some editable cells and I wanted to know if the updates could be sent back to the sql table. is there a way to set the updated datagrid to a new dataset and bind the new data to the existing sql table?

I'm using the HtmlAgilityPack to extract data from a html document. I can get the data to display in console.Writeline however I need to get it into a DataGrid/DataTable so I can import it into SQL Server. For the life of me I can't figure out how to get it into the DataGrid.

I have tried googling so much that I have given up trying to look. I am trying to display a dataset in a wpf datagrid. After that I am going to need to display the individual column value in textboxes. I can then change the value in those textboxes and pressing, say, a commit button, to commit the changes to a database. Here's the code I have so far.
Dim con As New SqlConnection Dim dbConnString As String Dim ds As New DataSet
