Have you tried using <a href="http://msdn.microsoft.com/en-us/library/system.windows.forms.form.showdialog(VS.71).aspx" rel="noreferrer">Form.ShowDialog()</a> instead of <a href="http://msdn.microsoft.com/en-us/library/system.windows.forms.form.show.aspx" rel="noreferrer">Form.Show()</a>?

ShowDialog shows your window as modal, which means you cannot interact with the parent form until it closes.

blocks|key|1504043|text|您是在父窗体的子窗体上调用ShowDialog()，还是仅在子窗体上调用Show()？|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|1504044|ShowDialog将“阻止”用户与作为参数传递给ShowDialog的表单进行交互。|1504045|在父级中，您可以调用类似以下内容：|1504046|MyChildForm+childForm+=+new+MyChildForm();

Are you calling <code>ShowDialog()</code> or just <code>Show()</code> on your child form from the parent form?

<code>ShowDialog</code> will "block" the user from interacting with the form which is passed as a parameter to <code>ShowDialog</code>.

Within the parent you might call something like:

<pre><code>MyChildForm childForm = new MyChildForm();

childForm.ShowDialog(this);
</code></pre>

where <code>this</code> is the parent form.

While using <code>Form.ShowDialog()</code>, you cannot interact with the parent form until it closes.

blocks|key|1504209|text|虽然使用前面提到的childForm.ShowDialog(这)会禁用您的主窗体，但它看起来仍然不是很禁用。但是，如果在调用ShowDialog()之前调用Enabled+=+false，在调用ShowDialog()之后调用Enable+=+true，那么主窗体看起来就像被禁用了一样。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1504210|var+childForm+=+new+Form();

While using the previously mentioned childForm.ShowDialog(this) will disable your main form, it still doesent look very disabled. However if you call Enabled = false before ShowDialog() and Enable = true after you call ShowDialog() the main form will even look like it is disabled.

<pre><code>var childForm = new Form();
Enabled = false;
childForm .ShowDialog(this);
Enabled = true;

You can also use MDIParent-child form. Set the child form's parent as MDI Parent

Eg

<pre><code>child.MdiParent = parentForm;
child.Show();
</code></pre>

In this case just 1 form will be shown and the child forms will come inside the parent.
Hope this helps

blocks|key|1504442|text|对我来说，这项工作，例如，这里发生了什么是主菜单将被禁用，当你打开注册表单。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1504443|+frmUserRegistration+frmMainMenu+=+new+frmUserRegistration();

For me this work for example here what happen is the main menu will be disabled when you open the registration form.

<pre><code> frmUserRegistration frmMainMenu = new frmUserRegistration();
 frmMainMenu.ShowDialog(this);

blocks|key|1289803|text|如果您只是试图模拟一个Form.ShowDialog调用，但又没有阻塞任何东西(有点像模拟的对话窗体)，那么可以尝试使用Form.Show()，一旦显示了模拟的对话窗体，就立即使用如下命令禁用所有其他窗口。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1289804|private+void+DisableAllWindows()

If you are just trying to simulate a Form.ShowDialog call but WITHOUT blocking anything (kinda like a Simulated Dialog Form) you can try using Form.Show() and as soon as you show the simulated dialog form then immediately disable all other windows using something like...

<pre><code>private void DisableAllWindows()
{
foreach (Form f in Application.OpenForms)
if (f.Name != this.Name)f.Enabled = false;
else f.Focus();
}
</code></pre>

Then when you close your "pseudo-dialog form" be sure to call....

<pre><code>private void EnableAllWindows()
{
foreach (Form f in Application.OpenForms) f.Enabled = true;
}
</code></pre>

blocks|key|1289433|text|为什么不干脆让父母等孩子关门。这超出了您的需要。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1289434|//+Execute+child+process

Why not just have the parent wait for the child to close. This is more than you need.

System.Diagnostics.Process proc = 
 System.Diagnostics.Process.Start("notepad.exe");
proc.WaitForExit();
