I ma not sure I understand your problem. There are 2 steps in displaying a
form.
1) Create a form object
2) Display the form
Between step 1 and 2, you can set the properties of the form, so if you
create your form, set whatever you want to pass into the object, you can see
that value in the load event of the form.
example class :
public class MyForm : Form
{
public int MyValueToLookInLoadEvent = 0;
public MyForm()
{
}
private void MyForm_Load( object sender, System.EventArgs e)
{
if (MyValueToLookInLoadEvent == 1)
DoSomething();
else
DoSomethingElse();
}
}
example main code
MyForm f = new MyForm();
f.MyValueToLookInLoadEvent = 1;
f.Show();
thats about it.
I guess you will need to decide what you want in MyValueToLookInLoadEvent
and the datatype of it, and other things. You can also have an overloaded
constructor of the form taking a parameter.
Sorry for the C# code, i know you are after VB.NET. Anyways, HTH,
