Well, don't call it button1, for a start ( that's just dumb )

You have properties on the form for the AcceptButton and CancelButton. These set what buttons are pressed by Enter and Escape

Check Visible property of button it has to be true, to be sure of it you may also set this property on Form load event.

Good Morning All

i have the Following App.Config file in VB2003 and a Windows Application.

<?xml version="1.0" encoding="utf-8"?>
<configuration>
	<appSettings>
		<!--   User application and configured property settings go here.-->
		<!--   Example: <add key="settingName" value="settingValue"/> -->
		<add key="timer.Enabled" value="True" />
		<add key="timer.Interval" value="1000" />
		<connectionstring>
		<add name ="Tshwane_Train"
		connectionString = "login=sde;Password=topology;Database=Tshwane_Valuations_Train;
		Server=SGIICORNETGS01"/>
		</connectionstring>
	</appSettings>	
</configuration>

and am Accessing this Connction string from the Vb App, like this

Dim constr As String = Configuration.ConfigurationSettings.AppSettings("Tshwane_Train")

When i compile the Application, i get no Errors ,but but when i try to run the application, i mean the Part that will need to Connect to the Database i get the Following Error.

An unhandled exception of

type 'System.Configuration.ConfigurationException' occurred in system.dll<br />
Additional information: Unrecognized element

What is Wrong

Thanks

You might try something like this:

connStr = My.Settings.ConnectionString

Works for me.

At First i saw my e-mail with this Code from you

Public Sub initializeDataConnection()

        Dim strConn As String

        Dim settings As ConnectionStringSettings

        settings = ConfigurationManager.ConnectionStrings _
              (WindowsApplication1.My.MySettings.APPProdConnectionString")

        If Not settings Is Nothing Then
            strConn = settings.ConnectionString
            cn = New SqlConnection(strConn)
        End If

    End Sub

and when i click to go to CodeProject, i see a Different Answer, did you change it?

let us look at the above code, i understand what you are doing and in the Following line where you declare like this

Dim settings As ConnectionStringSettings

The ConnectionStringSetting is not recognised, am using VS2003 and VB(Windows App) is this Applicable to it?

Thanks

Your app.config has a seperate section for connection strings. Have a google.

The "key" attribute (or node .. what is this thing anyway ?) does not have a connectiontring atrribute.

Use: <add key="keyname" value="value" /> and it should work...

you can skip the <connectionstrings> <connectionstrings /></connectionstrings> part too...

combobox Problem....

16-Jun-08 21:25

I am working in window based application

funFillCombo_prod(CmbProduct, "select productid,product from product_master where status=1")
CmbProduct.ValueMember = "productid"
CmbProduct.DisplayMember = "product"
CmbProduct.SelectedIndex = 0

In function I fill the combobox ……… by dataset
Public Function funFillCombo_prod(ByVal cmbCombo As ComboBox, ByVal strsql As String) As Boolean
Try
Dim intI As Integer
If con.State <> ConnectionState.Open Then con.Open()
GDataAdapter = New SqlDataAdapter(strsql, con)
GDataSet = New DataSet()
GDataAdapter.Fill(GDataTable)
cmbCombo.DataSource = GDataTable.DefaultView
funFillCombo_prod = True
Catch ex As Exception
MsgBox(Err.Source & " : " & Err.Description, vbInformation, g_MSG_Title)
funFillCombo_prod = False
Finally
GDataSet = Nothing
End Try
Exit Function
End Function

Private Sub CmbProduct_SelectedIndexChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles CmbProduct.SelectedIndexChanged
If CmbProduct.Items.Count > 0 Then
If CmbProduct.SelectedIndex <> -1 Then
MessageBox.Show(CmbProduct.SelectedValue.ToString())
End If
End If

End Sub

Problem is that in CmbProduct_SelectedIndexChanged I want valumember of a combobox

But msgbox which I write in that event is giving me the desired o/p but problem is that…
For two times I got this message System.Data.DatarowView. then I got the valuemember which I require,

Please tell me how to solve this System.Data.DatarowView. Problem

This means you have not set the ValueMember of the combobox, so it's showing the ToString of the object referred to

They aren't, unless your code creates them.

That's not smart. No-one will email you, except spammers. If you gave CP this email, CP will email you when you get a reply.

The picker has a Value property, which is the date. The rest is sufficiently trivial that if you don't know, you should buy a book or read some articles on basic SQL and basic ADO.NET, I really don't know how to explain this and feel sure you understand me without writing half a book.

I know you can find a variety of blowfish algorithm for .Net downloads on the Internet. Can you not just use what .Net has built-in via the System.Security.Cryptography namespace, or are you converting something that used to be encrypted with blowfish, and you prefer to continue with that encryption?
