Using VB 2008, I have a form which includes a richtextbox which is bound to a database field. When i bind the datafield to the richtextbox, I get an unformatted display unlike the control in VB6. How can I bind the data from the database to the richtextbox so that it displays formatted?

I have a code that binds the data from the database to textboxes. The problem is I want to make one of the textboxes Payment use a dollar sign.I tried formatting it as shown in the code below but only the first record gets formatted, the rest do not. When I click the next button, the dollar sign disappeared.
Here is a portion of the code:
bs = New BindingSource(ds, ds.Tables(0).TableName)
Me.txtPayment.DataBindings.Add("Text", bs, "Payment")
Me.txtPayment.Text = Format(CType(txtPayment.Text, Decimal), ("c"))
I have tried everything else I know, FormatCurrency but no luck.Payment is the name of the column in the database, the data type in SQL Server is Small Money.

I am creating a database in VB.NET for a movie rental place. I currently have three forms;
Member Information
DVD Information
Borrow DVDs
What I would like to do is when I am viewing a member's details, if I click a button 'Borrow DVD for Member', the member's ID number transfers over to the Borrow DVDs table in the Member ID which also would hold some information from the DVD Information table, but I'm sure if i can figure out how to do this firstly, I will be able to apply the same rule and work it out myself.I have been trying to use a query statement like;
INSERT INTO [Borrow DVDs].[Member ID] [IN goodstuffvideos.mdb]
SELECT [Member Information].[Member ID]
FROM [Member Information]
but that has been coming up with error codes and completely not working.
Borrow DVDs table fields are: Borrow ID, Member ID, DVD ID Number, Hiring Fee, Borrowing Limit?
DVD Information table fields are: DVD ID Number, Title, Rating, Hiring Fee, Borrowing Limit Member?
Information table fields are: Member ID, Family Name, Given Name, Address, Town/Suburb, Postcode?
The error coming up is; Error in INSERT statement. Unable to parse query text.And under that it says The query cannot be represented graphically in the Diagram and Criteria Pane.
I have a database that I would like to filter characters from anywhere in the field. Example the letter A is typed into textbox1 and in the grid every field that contains an A is show.

Dim filter1() As String
filter1 = TextBox2.Text.Split(" ")
Sheet1BindingSource.Filter = "Stationary_location like '" & filter1(0) & "' Stationary_location like '" & filter1(1) & "'"

View 4 RepliesI have made a front-end application in Visual Basic .NET that will store data entered by the user in a backend Access 2003 Database. The application has other functionality as well.If the user searchs for a previous record that has been stored in the Access Database, I query the Database (SELECT ... ) using an OLEDB Connection and then display the records on a Datagrid on my Form. Everything is working fine, however, the Column Headings of the Datagrid are the Field Names in my Database (FirstName, LastName,...) rather than Caption Values (First Name, Last Name,... )
I tried looking up the net, but most of the topics addressing a similar problems use DAO, and I understand that it is not completely supported in VB .NET.

View 1 RepliesI am working on an asp.net project in VS2010 using vb.NET (not VBA) designing an interface to allow a user to upload a file to an access 2007 table attachment field. My understanding is that in order to interface with a table with an attachment field you
must use DAO to connect to the database so that you can expose the attachment field properties. When I try to open the DAO recordset I am getting "COM exception was unhandled by user code" with a message stating "Too few parameters. Expected 3". The error code is -2146825227 and the stacktrace message is "at dao.Database.OpenRecordset(String Name, Object Type, Object Options, Object LockEdit)"
