程序运行的2个实例 [英] 2 instances of the program running

问题描述

我创建了一个VB.net Windows窗体应用程序。如果我运行程序

然后我再次错误地点击我的桌面图标，我会得到第二个运行该程序的
实例。无论如何都要检查/阻止

第二个实例启动，然后带我到已经运行的

应用程序。 （我已经看过过去的应用程序了...双击

点击桌面图标只会调出已经运行最少的

应用程序。）


非常感谢任何帮助！

I have created a VB.net windows forms application. If I have the program
running and then I mistakenly click on my desktop icon again, I get a second
instance of the program running. Is there anyway to check / prevent a
second instance to startup and just take me to the already running
application. (I have seen applications in the past do this... double
clicking on the desktop icon just brings up the already running minimized
application.)

Any help would be greatly appreciated!

如果您在VS / VB中搜索PrevInstance，您将获得以下代码

block


函数PrevInstance（）As Boolean

如果

Ubound（Diagnostics.Process.GetProcessesByName（Diag nostics.Process.GetCurrentProcess.ProcessName））

If you do a search for PrevInstance in VS/VB you will get the following code
block

Function PrevInstance() As Boolean
If
Ubound(Diagnostics.Process.GetProcessesByName(Diag nostics.Process.GetCurrentProcess.ProcessName))

0然后
返回True

否则

返回错误

结束如果

结束功能


只需从Sub Main调用它（）


Sub Main

如果不是PrevInstance那么

Dim MainForm作为新的Form1''（或其他）

Application.Run（MainForm）

结束如果

End Sub

0 Then Return True
Else
Return False
End If
End Function

Just call it from Sub Main()

Sub Main
If Not PrevInstance Then
Dim MainForm as new Form1 ''(or whatever)
Application.Run(MainForm)
End if
End Sub
