Hi
Suppose I have two forms: Form1 and Form2. I create and show an instance of
Form2 in the code of Form1 e.g.
Dim myForm2 = New Form2
myForm2.Show()
How do I tell myForm2 that Form1 is its parent? That is, when I look at
either "Parent" or "ParentForm" in Form2, they both show "Nothing".
Can anybody help???
Thanks in advance

您想以模态方式显示表单吗？

您好
感谢您的建议;虽然我不认为你的建议是
正是我需要的。
在Form2中，我有一个进度控件，我正在使用它在Form1中显示
计算进度。如果我正确理解ShowDialog，使用这个
，程序将在Form1中停止。我想我可以使用
线程，正如新闻组中的其他人所建议的那样，但是，我仍然认为必须有一种方法可以使用我拥有的技术来实现它描述即
在第一种形式中显示带有进度控件的表单，并从Form1中增加
控件，例如
theProgressControl.Increment（1）''在Form1中调用
这确实有效。但是，我希望第二种形式，即具有
进度控制的形式，以第一种形式为中心。我尝试过使用：
myForm2.StartPosition = FormStartPosition.CenterParent
但这不符合我的预期，即它不是'第一种形式为中心。
有人可以提供帮助吗？

Hi
Thanks for your advice; although I don''t think what you are suggesting is
exactly what I require.
In Form2, I have a progress control, which I am using to display the
progress of calculations in Form1. If I understand ShowDialog correctly,
using this, the program will stop within Form1. I suppose I could use
Threads, as others in the newsgroup have kindly suggested, however, I still
think there must be a way to do it using the technique I have described i.e.
show the form with the progress control in the first form, and increment the
control from within Form1 e.g.
theProgressControl.Increment(1) '' This is called within Form1
This does indeed work. However, I want the second form i.e. the one with the
progress control, to be centered in the first form. I''ve tried using:
myForm2.StartPosition = FormStartPosition.CenterParent
but this does not do what I expect i.e. it isn''t centered on the first form.
Can anybody help?
