可靠地找到进程的路径...Win XP、Vista 和 7

总之，

我在互联网上进行了研究，发现了很多潜在的解决方案，但我在 Windows 7 计算机上不断收到错误。

这是独家新闻。我有一个用 VB.NET 编写的应用程序，它启动一个控制台应用程序。控制台应用程序将独立于我的 VB.NET 应用程序运行，因此用户可以关闭并重新启动 VB.NET 应用程序，并可能从同一安装启动控制台应用程序的第二个会话。

我不想要这个。我想在 VB 应用程序启动时识别正在运行的控制台应用程序的实例，并禁用第二次、第三次等运行控制台应用程序的功能。时间。但是...我只想在控制台应用程序与 VB.NET 应用程序位于同一文件夹中启动时禁用此功能。

这是我当前使用的代码：公共函数 CheckForConsoleApp() 作为布尔值 '检查控制台应用程序是否正在该文件夹中运行。如果是则返回 true。

    Dim p() As System.Diagnostics.Process
    p = System.Diagnostics.Process.GetProcessesByName("MyConsoleApp")
    If p.Length = 0 Then return false

    Dim Path As String = My.Application.Info.DirectoryPath
    Dim i As Integer
    For i = 0 To p.Length - 1
        Dim pPath As String = p(i).MainModule.FileName
        pPath = pPath.Substring(0, pPath.LastIndexOf("\"))
        if pPath = Path Then Return True
    Next i

    Return False

End Function

在我的系统（32 位 Windows XP）上，这不是问题，并且每次都有效。在同事的 64 位 Windows 7 计算机上，生成错误，只能完成“ReadProcessMemory 或 WriteProcessMemory”的一部分。使用日志文件和其他努力表明：

Dim pPath As String = p(i).MainModule.FileName

行是发生故障的地方。

我们的应用程序必须在 Windows 7、Vista 和 XP 计算机上运行，无论是 32 位还是 64 位平台。我发现 WinAPI 命令可以将读/写权限应用于某些内存位置，但这些命令专门与 ReadProcessMemory API 命令一起使用，因此我还没有看到如何在 .NET 中应用类似的命令。

帮助？谢谢， SH

All,

I have researched the Internet and found more than a few potential solutions, but I keep getting errors on a Windows 7 machine.

Here's the scoop. I have an application written in VB.NET that launches a console application. The console application will run independently of my VB.NET app, so the user can close and restart the VB.NET app and potentially start a second session of the console app from the same installation.

I don't want this. I want to identify instances of the running console app when my VB app starts, and disable the ability to run the console app a second, third,...etc. time. But...I only want to disable this ability when the console app has been launched from the same folder as the VB.NET app.

Here's the code I'm using currently:
Public Function CheckForConsoleApp() As Boolean
'Check to see if console app is running in this folder. Retrun true if so.

    Dim p() As System.Diagnostics.Process
    p = System.Diagnostics.Process.GetProcessesByName("MyConsoleApp")
    If p.Length = 0 Then return false

    Dim Path As String = My.Application.Info.DirectoryPath
    Dim i As Integer
    For i = 0 To p.Length - 1
        Dim pPath As String = p(i).MainModule.FileName
        pPath = pPath.Substring(0, pPath.LastIndexOf("\"))
        if pPath = Path Then Return True
    Next i

    Return False

End Function

On my system (32 bit Windows XP) this is not a problem, and it works every time. On a co-worker's 64-bit Windows 7 machine, an error is generated that only a portion of the "ReadProcessMemory or WriteProcessMemory" can be completed. The use of log files and other efforts have shown that the:

Dim pPath As String = p(i).MainModule.FileName

line is where the failure occurs.

Our application has to work on Windows 7, Vista, and XP machines, on both 32-bit and 64-bit platforms. I've found WinAPI commands to apply read/write permissions to certain memory locations, but those were specifically used with ReadProcessMemory API commands, so I've yet to see how to apply similar commands in .NET.

Help?
Thanks,
SH
