Can you use just a connection string to connect to a database or do you always have to define it using the database connection dialog? I am using vb.net 2005 express. Also if not is it possible in another language?

Sure. It's a Connection String. All you need to do is specify what the SQL Server name is and the database to use:
Dim conn As New SqlConnection("Data Source=serverName;Initial Catalog=databaseName")
This is, of course, a bit different for an Access database:
Dim conn As New OleDbConnection("Provider=Microsoft.Jet.OLEDB.4.0;Data Source=filePath;")

This is what I am using to populate a combo box.
cboSectionTitle.DataSource = premiumsListDataSet
cboSectionTitle.DisplayMember = "SectionTitle"
cboSectionTitle.ValueMember = "SectionID"
I get an error on the ValueMember line as follows:
can not bind to the new display member
I think there is a problem with the data but do not see what it is.
P.S. The SectionID column is not unique
in the table the fields parentID and SectionID are both primary keys
Thanks

Does that DataSet object have more than one table?? Bind to the appropriate Table or DataView in the DataSet, then the DisplayMember and ValueMember will actually mean something.

Google for ""vb fingerprint free"[^]" and you should find what you're looking for.

Could you be more specific? Do you mean that you have strings with numbers in decimal format that you want to convert to strings with numbers in binary format?

I need to print Code 39 barcodes on a Star printer. In order to do this I need to send a series of control string directly to the priter like Chr(27) + Chr(98) + Chr(52) + Chr(50) + Chr(49) + Chr(57) + message+ Chr(30).
How could I code suing the System.Drawing.Printing object. I've tried to using DrawString function, but I've just get the text printed out, not the bar code.
Anyone have any suggestion

Hi
I'm using the combo selectedIndexChanged Event to trigger the population of a lot of data (Indented Bill of Materials).
If the combo has focus and you move the mouse wheel... Well lots of events and lots of data.
How can I disable the mousewheel for this combo.
I tried to use e.handled in the mousewheel event, but handled is not a method that can be used.
Any ides?
Cheers
Richard

the erro:
Format of the initialization string does not conform to specification starting at index 0.
"Dim Myconn As New SqlClient.SqlConnection("ConnectionString2")"
this is the problem line.

|

The connection object will not read the value from the config file, you have to do that yourself and pass the value to the connection object.

Example from MSDN:
Public Sub ReadMyAppSettings()
Dim appName As String
appName = ConfigurationSettings.AppSettings("Application Name")
Console.WriteLine()
Console.WriteLine("Reading AppSettings")
Console.WriteLine("Application Name: " & appName)
End Sub
The ConfigurationSettings class is in the System.Configuration namespace.

Hi guys,
When I used visual studio 7, to send a mail I used System.Web.mail.namespace .
''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''
Imports System.Web.Mail
Public Class Form1
Dim obj As System.Web.Mail.SmtpMail
Dim Attachment As System.Web.Mail.MailAttachment
Dim message As New System.Web.Mail.MailMessage()
Private sub send_Mail()
obj.SmtpServer = text_Server.txt
message.to = text_To.txt
message.from = "\" & txtFromDisplayName.Text & "\ <" & txtFrom.Text & ">"
message.BodyFormat = MailFormat.Text
message.Subject = text_Subject.Text
message.Body = txtMessage.Text
Try
obj.Send(message)
catch ex as Exception
MsgBox("Problem with sending..please retry!",,"Attention!")
End Try
End sub
End Class
'''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''
Now in Visual Studio 2005 (8), when I try the same code, the program "suggests" me to use the latest System.Net.Mail.namespace because System.Web.Mail.namespace is absolete!
So,is there someone to help me with this? I try to find examples in Web, but I find only examples in C# .net not in vb .net. Help me please!
Thanx in advance..   ;)

The syntax is mostly the same. Use:
<br />
Dim obj As System.Net.Mail.SmtpClient <br />
Dim Attachment As System.Net.Mail.Attachment<br />
Dim message As New System.Net.Mail.MailMessage<br />
A couple of the parameters are different - for example .host instead of .SmtpServer, but apart from that it's pretty much the same. Intellisense should be able to fill in anything else you need.
