Hey guys, so im really knew to aspx. I'm trying to create a registration form that connects to my access database and once a user registers it sends their information to the database.
But when i run my code it goes straight to catch as exception.
Here is my code,the code i have colored in red below may be causing the problem as i do not know exactly how to code it.
Suggestions would be appritiated.

<script runat="server">
Dim conn As New OleDbConnection("provider=microsoft.Jet.OLEDB.4.0;" & _
"Data source=" & AppDomain.CurrentDomain.BaseDirectory & "App_Data\webproject1.mdb")
Dim sqlcomand As New OleDbCommand

Protected Sub Button1_Click(ByVal sender As Object, ByVal e As System.EventArgs)

sqlcomand.Connection = conn
sqlcomand.CommandText = "insert into Registration " & _
"(FirstName,LastName,Age,Gender,Address,PostCode,Email,Username,Password) Values " & "('" & _
txtfirstname.Text & "'," & _
txtlastname.Text & "," & _
txtage.Text & ",'" & _
txtgender.Text & "'," & _
txtadress.Text & "," & _
txtemail.Text & ",'" & _
txtusername.Text & ",'" & _
txtpassword.Text & "')"
MsgBox("thanks for registering please login")

Catch ex As Exception
MsgBox("Error you cannot register")
End Try
End Sub

The problem is with your msgbox() command.
The msgbox is trying to display on server.
It cannot hence error.
You need to use a clientscript (javascript) and use it with asp.net to display alert(). There are many articles on Internet on this.
Search "Page.ClientScript"

Most simple way is to use:

Response.Write("<script type=\"text/javascript\"> alert('thanks for registering please login');</script>");

Alternatively you could do something like this.

Dim scriptBlock As String = "<script type=""text/javascript"">"
scriptBlock += "alert('thanks for registering please login');"
scriptBlock += "</script>"
ClientScript.RegisterClientScriptBlock(Page.GetType(), "scriptKey", scriptBlock)

With this method you can access and modify the script block server side using the provided key "scriptKey".

Hope it helps.
