I have created a simple usercontrol in c# . It consist of three textboxes.

I have written a method in usercontrol to set the values in these textboxes

public partial class Win : UserControl

{

public Win()

{

InitializeComponent();

}

private void button1_Click(object sender, EventArgs e)

{

textBox3.Text = textBox1.Text + textBox2.Text;

}

public void CalVal()

{

textBox1.Text = "My";

textBox2.Text = "Name";

textBox3.Text = "Neeraj";

}

}

It is successfully registered as COM component .

When i use it in VB6 i am not able to set the values in these textboxes

Dim objControlNew As Try.Win

Private Sub Command2_Click()

Dim str As String
Dim strnew As String

Set objControlNew = New Try.Win

Me.Controls.Add objControlNew, "dotnet"
Me.Controls("dotnet").Visible = True
objControlNew.CalVal
End Sub

I am just calling the method , values are set from usercontrol , but i am not able to see the values in the textboxes.

Please help if anyone know the solution

The scenario you're trying is actually unsupported unless you use the Interop Toolkit 2.0 (http://msdn2.microsoft.com/en-us/vbasic/bb419144.aspx). The templates for that are only in VB, but someone posted a C# translation over at CodeProject: http://www.codeproject.com/useritems/VB6InteropToolkit2.asp.

If you're building your .NET component in VB it's as simple as using the ComClass attribute; if you're using C# there's some extra work involved. Check out http://blogs.msdn.com/vbteam/archive/2007/06/01/so-what-does-lt-comclass-gt-actually-do.aspxfor more info.

Hope that helps,

@Naren7:
Not sure if this is relevant, but here goes:

If you are using the control in C# (MyControl for example), you can instantiate the control directly in code:

MyControl txtControl = new MyControl();
txtControl.Parent = this;
txtControl.Size = new Size(20, 60);
txtControl.Location = new Point(5, 5);
txtControl.Text = "";

Take a look at exactly what InitializeComponent() does in your form's constructor. That's what instansiates all the controls that you drag onto the form designer.
