Registry in VB Express 2005

I want to store the information in the form into the registry.



Heres my code:

Code:

---

Private Sub Button3_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button3.Click

Dim Value As String

Value = ComboBox1.Text

My.Computer.Registry.CurrentUser.CreateSubKey("MRU")

My.Computer.Registry.SetValue("HKEY_CURRENT_USER\Software\Microsoft\Terminal Server Client\", _

"MRU", "" & Value)

End Sub

---

If I press Button3, it creates a value "MRU" in HKEY_CURRENT_USER\Software\Microsoft\Terminal Server Client\

BUT.. If I put something else in the ComboBox, it overwrites the registry value when I press Button3 again.

How is it possible to make it add MRU1, MRU2, ect ?



Now I have MRU0 to MRU10 in the registry.

If I press the Button3 now, it creates MRU key, but if I edit the value in the combobox, it overwrites.

I want it to create MRU11, MRU12, ect...



Thanks in advanced!

Post this question in the .NET forum please.

I've moved your thread.

If you run My.Computer.Registry.SetValue("HKEY_CURRENT_USER\Software\Microsoft\Terminal Server Client\", "MRU", "" & Value), it will set the value of MRU. To set the value of MRU1, you have to run My.Computer.Registry.SetValue("HKEY_CURRENT_USER\Software\Microsoft\Terminal Server Client\", "MRU1", "" & Value). You can use a variable for the number - My.Computer.Registry.SetValue("HKEY_CURRENT_USER\Software\Microsoft\Terminal Server Client\", "MRU" & iCounter, "" & Value).

okay.
I got it..
But.. One more question though..
When I press "Button3", it overwrites the MRU0... I want it to add the next one..
Let's say i have MRU0, MRU1, MRU2.

I have this in the code:

Code:

---

        My.Computer.Registry.SetValue("HKEY_CURRENT_USER\Software\Microsoft\Terminal Server Client\Default", _
        "MRU" & iCounter, "" & Value)

---

Now..
When I press "Button3", I want it to add MRU3 to the registry automaticly.
And when I press "Button3" again after that, I want it to add MRU4 to the registry automaticly.

You guys with me now??

You can consider setting your iCount as a class level variable and increment it every time you click the button.

vb.net Code:

' My count.
    Private iCount As Integer = 0
 
    Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
        ' Do something with my count.
        MessageBox.Show(iCount.ToString())
        ' Increment the count.
        iCount += 1
    End Sub

Good luck.

Okay!
Thanks! Saved my day ;)

Ok..

What is the code for when I close (exit) the form?

Is it:

Code:

---

Private Sub Form1_Close(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Leave
End Sub

---

??

One more thing about the registry...

If .. lets say 'test' value exists in the registry...
Like..

Name:
'Test0'

Type:
REG_SZ

Value:
Test.Test

And when I press 'Button3', it creates Test1 with the value 'Test.Test'..
(If 'Test.Test' is in the combobox that is!)

I want it to NOT save it in to the registry if the value 'Test.Test' exists...
How is this possible?

Thanks!

To insert the code for a certain control's events you can:
1) Select the control in the desinger and click the Events button (lightening bolt) in the Properties window.
2) In code view in the left combo box select the desired control and then in the right combo box select the desired event

What about my last post? the one with 'Test.Test' ...?

You can do something like this to check for a key (example 1) or a value in the key (example 2):

vb.net Code:

' Check for a key in the registry.
        Dim key As Microsoft.Win32.RegistryKey = My.Computer.Registry.LocalMachine.OpenSubKey("SOFTWARE\Microsoft\Windows\CurrentVersion")
        If key IsNot Nothing Then
            MessageBox.Show("Found the key")
        Else
            MessageBox.Show("Didn't find the key")
        End If
 
        ' Check for a value in the key.
        If My.Computer.Registry.GetValue("HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion", "ProductId", Nothing) IsNot Nothing Then
            MessageBox.Show("Found the value")
        Else
            MessageBox.Show("Didn't find the value")
        End If

Hope that helps.
