将已经运行的应用程序带到前面 [英] bring an already running app to the front

问题描述

我的程序会检查另一个程序是否已在运行，如果是这样的话

我希望它能够恢复因为windows把它放到了其他程序，所以它b / b
出现在屏幕上的其他任何内容之上。我知道如何检查

看看它是否正在运行


如果是UBound（System.Diagnostics.Process.GetProcessesByNa me（programX）） ）> 1

然后


那么什么？如何让programX恢复？


谢谢

解决方案

我应该注意到我'使用VB2003

AFAIK，唯一的方法是使用Windows API调用：


私有声明函数ShowWindow Lib" user32" _

（ByVal hWnd As System.IntPtr，ByVal nCmdShow As Long）As Long


Private Const SW_RESTORE = 9


然后当你想恢复窗口时：


Dim procArray As System.Diagnostics.Process

Dim proc As System.Diagnostics.Process


procArray = System.Diagnostics.Process.GetProcessesByName（" pro gramX"）

如果procArray.Length> 0然后

proc = procArray（0）

ShowWindow（proc.MainWindowHandle，SW_RESTORE）

结束如果


我几乎建议使用AppActivate（proc.Id）代替对ShowWindow（）的

调用（AppActivate可以直接使用而不需要

Imports语句;它是Microsoft.VisualBasic.Interaction

名称空间的一部分），但是如果你在一个最小化的窗口上调用AppActivate，它实际上不会是
恢复窗口，它只是激活任务栏而没有

最小化它，这在我看来有点毫无意义。

My program checks to see if another program is already running and if so
I want it to "restore" as windows puts it that other program so it
appears on top of anything else on the screen. I know how to check to
see if it''s running

If UBound(System.Diagnostics.Process.GetProcessesByNa me("programX")) > 1
then

then what? How do I get programX "restored"?

Thanks

解决方案

I should have noted I''m using VB2003

Cj,

I thought that it was this one,
http://msdn2.microsoft.com/en-us/lib...ngtofront.aspx

There is as well a topmost property but that is anoying, it never goes back.

I hope this helps,

AFAIK, the only way to do this is to use a Windows API call:

Private Declare Function ShowWindow Lib "user32" _
(ByVal hWnd As System.IntPtr, ByVal nCmdShow As Long) As Long

Private Const SW_RESTORE = 9

And then later when you want to restore the window:

Dim procArray As System.Diagnostics.Process
Dim proc As System.Diagnostics.Process

procArray = System.Diagnostics.Process.GetProcessesByName("pro gramX")
If procArray.Length > 0 Then
proc = procArray(0)
ShowWindow(proc.MainWindowHandle, SW_RESTORE)
End If

I was almost going to suggest using AppActivate(proc.Id) instead of the
call to the ShowWindow() (AppActivate can be used directly without an
Imports statement; it''s part of the Microsoft.VisualBasic.Interaction
namespace), but if you call AppActivate on a minimized window, it won''t
actually restore the window, it just activates it the taskbar without
unminimizing it, which is kinda pointless in my opinion.
