vb.net表单..一次只能启用一个表单 [英] vb.net forms ..enable only one form at a time

问题描述

我必须表单..当我单击form1中的按钮时，第二个表单form2应该显示。但我不能在关闭form2之前选择form1。我怎么能这样做？

I have to forms.. when I click a button in form1 the second form form2 should show. but I should not be able to select form1 before closing form2 . how can I do that?

推荐答案

只需创建新实例，并使用ShowDialog代替Show：

Just create the new instance, and use ShowDialog instead of Show:

Dim fs As New frmSecond()
fs.ShowDialog()

在frmSecond实例关闭之前，原始表单将不执行任何操作。

The original form will do nothing until the frmSecond instance is closed.
