如何突出显示由form_1创建的form_2 [英] How to highlight the form_2 which is created by form_1

问题描述

改进的问题

回答2:谢谢，但我不能只显示它.

回答1:
(1)如果我不添加"this.Controls.Add(form_2)"行，则form_2将显示在form_1后面.因此，我将这行添加到form_1的行下方的form_1中，以便form_2可以显示在form_1客户区中.

另外，我必须在"this.Controls.add(form_2)"之前添加"form_2.toplevel=false"，否则它将显示"无法将顶级控件(form_2)添加到控件(this)"的消息，并且则无法在高级版本中运行.

(2)加亮表示让form_2中的顶部栏具有加亮的蓝色.因为即使单击form_2或在form_1中添加以下任何一行，也只能看到form_2中顶部栏的灰色蓝色:

Improved question

To Answer 2 : Thanks, but I am not to show it only.

To Answer 1 :
(1) If I don''t add the line of "this.Controls.Add(form_2)", the form_2 will be shown behind the form_1. So, I add this line in form_1 just below the line of "initialcomponet()", so that the form_2 can be shown in the form_1 client area.

Plus, I have to add "form_2.toplevel=false" before "this.Controls.add(form_2)", or, it will show message of "can not add top level control(form_2) to control(this)", and then it can not run in advanced.

(2) The highlight means to let top bar in form_2 has highlight blue color. Since I can only see gray blue color of top bar in form_2 even I click the form_2, or add any line of following in form_1 :

form_2.Show();
form_2.Activate();
form_2.Enabled = true;
form_2.BringToFront();
form_2.Focus();

第一个问题

我有一个名为form_1的窗体的winform应用程序，我在form_1中编写代码来创建form_2，我想用突出显示颜色激活form_2，但是失败.代码如下:

1.我创建form_2并将其包含在form_1 (this)
中

First question

I have a winform application with a form named form_1, I write code in form_1 to create form_2, and I would like to activate the form_2 with highlight color, however, it fails. The code is below :

1. I create form_2 and let it be included in form_1 (this)

Form_help form_2 = new Form_help();
form_2.TopLevel = false;
this.Controls.Add(form_2);

2.我尝试用以下几行激活form_2以突出显示它，但是所有操作都没有突出显示它.

2. I try to activate form_2 to highlight it with the following lines, but all fails to highlight it.

form_2.Show();
form_2.Activate();
form_2.Enabled = true;
form_2.BringToFront();
form_2.Focus();

问题是如何突出显示form_2?由于我将在form_1中放置多个表单，并且当单击任何表单时，单击的表单将突出显示.

我也尝试使用form_1.activecontrol(form_2)方法，但仍然失败.

The question is how can I highlight the form_2? Since I would place multiple forms in form_1, and when click any of the forms, the clicked form will be highlight.

I also try the way of form_1.activecontrol(form_2) method, but it still fails.

推荐答案

您是否要使表格1包含多个表格?如果是这样，请尝试使用mdi父容器. <-推荐使用以下解决方案.

否则，您可以使用P/Invoke:
http://www.pinvoke.net/default.aspx/user32.setforegroundwindow

它将任何窗口设置为前景窗口，或者至少尝试使用它，只需使用this.Handle即可获取表单的句柄.

Are you trying to make form 1 contain multiple forms? If so, try using a mdi Parent Container instead. <-- Recommended over solution below.

Otherwise you can use P/Invoke:
http://www.pinvoke.net/default.aspx/user32.setforegroundwindow

It''ll set any window to the foreground window or atleast try to, just use this.Handle to get the form''s handle.

Form_help f = new Form_help();
f.ShowInTaskbar=false;
f.backcolor=color.red;
f.windowstate=formwindowstate.maximized;
f.show();

表单不是控件，您不将其添加到控件集合中.

突出显示是什么意思?

A form is not a control, you don''t add it to the controls collection.

What do you mean by highlight ?
