如何：从Main函数最大化窗口？ [英] How to: Maximize window from the Main function?

问题描述

在我的表单的主要功能中，我检查应用程序是否已经运行了
。如果是，我会抛出一个告诉用户的消息框。我想要做的事情也是最大化应用程序，但我无法这样做。

任何人都有这方面的经验。


TIA，

马特

In the main function of my form I check to see if the application is already
running. If it is, I throw up a message box telling the user. What I would
like to do is also maximize the application, but I am unable to do so. Does
anyone have any experience with this.

TIA,
Matt

推荐答案

这不会将窗口设置为最大化，但它具有基本相同的影响。我认为有

Dim ScrnRec As Rectangle

ScrnRec = Screen.PrimaryScreen.Bounds（）


Me.Top = ScrnRec .TOP

Me.Left = ScrnRec.Left

Me.Width = ScrnRec.Width

Me.Height = ScrnRec.Height
您也可以尝试...


Me.WindowState = FormWindowState.Maximized

This won''t set the window to maximized, but it has
basically the same affect. I think there is
Dim ScrnRec As Rectangle
ScrnRec = Screen.PrimaryScreen.Bounds()

Me.Top = ScrnRec.Top
Me.Left = ScrnRec.Left
Me.Width = ScrnRec.Width
Me.Height = ScrnRec.Height
You could also try...

Me.WindowState=FormWindowState.Maximized

试试这个：

this.WindowState = FormWindowState.Maximiz

但是你不能从Main那里做 - 使用构造函数或者OnLoad事件或

无论什么

try this:
this.WindowState = FormWindowState.Maximiz
but you cant do it from Main - use the constructor or or the OnLoad event or
whatever

我假设您将杀死第二个实例并激活第一个实例，

如果是这样，您只需调用SetActiveWindow API：


[DllImport（" user32.dll"）]

IntPtr SetActiveWindow（IntPtr hWnd）;


这个诀窍。


你需要第一个应用程序的hWnd，如果你需要代码让它让我知道。


希望这个帮助，

Hi,

I assume that you will kill the second instance and activate the first one,
if so all you have to do is call SetActiveWindow API:

[DllImport("user32.dll")]
IntPtr SetActiveWindow( IntPtr hWnd);

This will do the trick.

You need the hWnd of the first app, if you need code to get it let me know.

Hope this help,
