以编程方式控制其他窗口控件 [英] Control other windows controls programatically
问题描述
大家好!,$
我正在尝试从当前窗口访问另一个窗口,并设法完成所有工作,例如启动后台工作那个窗口等等。
不幸的是,我遇到了问题,我通常使用这一行:
Window2 frm = new Window2();
我已完成以下操作:
public MainWindow()
{
InitializeComponent();
MessageBox.Show(" Check 1");
Window2 frm = new Window2();
MessageBox.Show(" Check 2");
}
该行给出了以下错误:
调用目标抛出了异常。

Hi everyone!,
I'm trying to accessing another window from my current window and manage to do all the stuff like starting a backgroundworker in that window, etc.
Unfortunately, I'm having a problem, I usually use this line:
Window2 frm = new Window2();
I've done the following:
public MainWindow() { InitializeComponent(); MessageBox.Show("Check 1"); Window2 frm = new Window2(); MessageBox.Show("Check 2"); }
That line gives me the following error:
Exception has been thrown by the target of an invocation.
What is the cause of this problem ?
help please
