应用已经运行？ [英] App already running?

问题描述

嘿所有，

另一个转换为vb.net。我的vb6程序是一个应用程序

启动程序，用于检查所述程序的先前实例，并且将使用消息框警告用户
。对于我的生活，我不能想象如何在vb.net中执行此操作。让我们说notepad.exe（作为一个例子）已经运行了
。我的程序试图再次启动它，但我需要

检查notepad.exe是否已经在我启动之前运行。


有没有人剪断编码来帮助我吗？我已经用Google搜索了我的屁股，而我最接近的就是检查/ my / app之前的

实例，我甚至都不能得到/那/上班。


听起来很简单，但我很难过。


感谢您的帮助！

Hey all,
Another convert to vb.net here. My vb6 program was an application
launcher that checked for previous instances of said programs and would
alert the user with a message box. I can''t, for the life of me, figure
out how to do this in vb.net. Let''s say notepad.exe (as an example) is
already running. My program tries to launch it again, but I need to
check if notepad.exe is already running before I launch it.

Does anyone have a snipped to code to help me out here? I''ve googled
my arse off and the closest I can get is to check for a previous
instance of /my/ app, and I can''t even get /that/ to work.

Sounds simple, but I''m stumped.

Thanks for any help!

推荐答案

我确定有一个可以满足您需求的Windows API。我或许能够找到它，但现在没有时间。同时，祝你好运

I''m sure there''s a windows API that will do just what you want. I may be able
to find it, but don''t have time right now. Meanwhile, good luck

这里是我为VB6创建的一些代码 -


公共声明函数GetWindow Lib" user32" （_

ByVal hwnd As Long，_

ByVal wCmd As Long _

）As Long


Public Declare Function GetWindowText Lib" user32" _

Alias" GetWindowTextA" （_

ByVal hwnd As Long，_

ByVal lpString As String，_

ByVal cch As Long _

）As Long


公共声明函数GetWindowTextLength Lib" user32" _

Alias" GetWindowTextLengthA" （_

ByVal hwnd As Long _

）As Long


Public Const GW_HWNDFIRST = 0

公共Const GW_HWNDLAST = 1

Public Const GW_HWNDNEXT = 2

Public Const GW_HWNDPREV = 3

Public Const GW_OWNER = 4

Public Const GW_CHILD = 5

Sub LoadTaskList（FHandle As Long，Wins

Here''s some code I created for VB6 --

Public Declare Function GetWindow Lib "user32" ( _
ByVal hwnd As Long, _
ByVal wCmd As Long _
) As Long

Public Declare Function GetWindowText Lib "user32" _
Alias "GetWindowTextA" ( _
ByVal hwnd As Long, _
ByVal lpString As String, _
ByVal cch As Long _
) As Long

Public Declare Function GetWindowTextLength Lib "user32" _
Alias "GetWindowTextLengthA" ( _
ByVal hwnd As Long _
) As Long

Public Const GW_HWNDFIRST = 0
Public Const GW_HWNDLAST = 1
Public Const GW_HWNDNEXT = 2
Public Const GW_HWNDPREV = 3
Public Const GW_OWNER = 4
Public Const GW_CHILD = 5
Sub LoadTaskList(FHandle As Long, Wins

（））

''加载字幕和Wins中所有窗口的句柄

())
''loads captions and handles of all windows in Wins
