I think I got it working! Here's what I did:
1) From my C# class, I declared a delegate variable, like so:
public partial class DelegateForm : Form
{
Delegate vbDelegate;
...
2) Now I implemented a C# method that takes a vb delegate as a
parameter. This method
gets called from VB:
public void exportDelegate(Delegate AVBDelegate)
{
vbDelegate = AVBDelegate;
}
3) Now that we have the delegate instance in place, we can invoke the
vb method *through* it. We can now
send the textBox value from C# to the Listbox found in the VB
form:
private void btnSendToVB_Click(object sender, EventArgs e)
{
vbDelegate.DynamicInvoke(textBox.Text);
}
