I realise this is an old post but it might help someone else out.
I needed to do a similar thing but I didn't want to concatinate fields in the sql used to fill the datatable as it was contained in an existing stored procedure. So I filled the datatable with the records I wanted then basically added another column in the datatable which was my concatinated display value. I then used this new column as the DisplayMember.
assuming we have a datatable which is populated with "AccountCode" and corresponding "AccountName"
eg "ABC" , "Freds workshop"
"XYZ" , "Bills Lighting"
'Add a new calculated column to the datatable
Dim DataCol As DataColumn = New DataColumn("Display")
DataCol.DataType = System.Type.GetType("System.String")
DataCol.Expression = "AccountCode + (' - ') + AccountName"
dt.Columns.Add(DataCol)
'Now setup the combobox
cmbAvailableCompanies.DataSource = dt
cmbAvailableCompanies.DisplayMember = "Display"
cmbAvailableCompanies.ValueMember = "AccountsCode"
It will now display "ABC - Freds Workshop" and "XYZ - Bills Lighting" in the combobox.
The only issue I have found is if I turn sorting of the combobox on the SelectedValue of the combobox gets out of sync with the Displayed value. I haven't worked this out yet but for the time being I can live with it.

Hi!
How do I allow the user to reload the main form of the application? In essence, I want a button that closes the whole program and opens it again, starting from scratch.
thanks
|

|

Write a method that sets the initial state of your controls and variables, call it in your form load ( so it always works the same ) and call it again from a button event.

What is wrong with my statement?
Dim mySelectQuery As String = "SELECT * FROM table where Rdate between '" & FromDate.Value & "'" And "'" & ToDate.Value & "'"
Rdate is a value from the database.
I get this error : Cast from string "SELECT * FROM table where recv" to type 'Long' is not valid.
Thank you
|

All 3 expressions for between must be the same datatype. If Rdate is from Type Date you must convert FromData.value and ToDate.value to a Date. This conversion depends on the database system. Look there for more information. If you use SQLServer see in Transact-SQL-Help for command 'CAST', 'CONVERT','BETWEEN' and 'DATETIME'.

Stephan

Try this (Assuming RDate is of DateTime type):
"SELECT * FROM table where Rdate between #" & FromDate.Value & "#" And "#" & ToDate.Value & "#"
I'd love to help, but unfortunatley I have prior commitments monitoring the length of my grass. :Andrew Bleakley:

You inject values into the SQL, which is a security risk and causes other problems.
Use parameterised queries instead of injecting values.

Hi all,
does anyone know about how to build a Email sending function in a website? cause we are trying to enable customers to send news and some images of our products to their friends. Our news is storded in an XML file.when we display the News we will use the XMLReader to read the whole content in the XML file and save it with some reasonable html codes into a string variable. And then display the sting variable in a label. When we run it, the formated content will be display.
And we would like to send the same News page or at least some formated XML content file to the customers' friends.
But the email we managed to send can only send string, no pictures allowed. and when we send Label1.text, it send all the stings instead of the formated page.
Can anyone help!!!

Hello Jackie,
see code below. It's easy to extend it to send attachments. Look at MSDN for the both classes.
Private Sub SendMail(ByVal Sender As String, ByVal Subject As String, ByVal Body As String)
Dim oSmtp As System.Web.Mail.SmtpMail
Dim oMailMsg As New System.Web.Mail.MailMessage
oMailMsg.From = Sender
oMailMsg.To = "recv1@account.com;recv2@account.com"
oMailMsg.Body = Body
oMailMsg.BodyFormat = System.Web.Mail.MailFormat.Html
oMailMsg.Subject = Subject
oSmtp.SmtpServer = ConfigurationSettings.AppSettings("MailServer")
oSmtp.Send(oMailMsg)
oMailMsg = Nothing
End Sub
Regards
Stephan
