在我的主窗体上,我有一个 ListView,其中包含属于我们软件套件的进程的 LargeIcon 视图列表。每个 LV (ListView) 项目都包含文本和图像,该图像与我们的软件产品的图标相同,用于相应的应用程序(即 MarinaOffice、LaunchOffice、PureRental 等)。有一个计时器根据是否在 Process.GetProcesses() 方法调用中找到进程来更新列表。当用户单击正在运行的进程的 ListView 项时,它应该最大化并在当前进程前面显示该进程(即 WinForms 应用程序)的窗口。下面的代码几乎可以完成我想要完成的工作,但是,如果我想要显示的应用程序已经最大化,但是在我在监视器上的 windows 应用程序后面,它没有将我展示的过程放在我的应用程序前面。换句话说,只要我使用下面的 WIN32 方法显示的应用程序被最小化,它就可以工作。但是,它已经最大化,它没有。

// Used to Show Other Process Windows
private const int SW_SHOWMAXIMIZED = 3;
[DllImport("user32.dll")]
static extern bool ShowWindow(IntPtr hWnd, int nCmdShow);    

// Method that checks for running apps in our suite every 3000ms
private void timerRunningApps_Tick(object sender, EventArgs e)
{
    CheckRunningapps();
}

// Stripped down version of method that looks for running process in our suite and 
// adds the process name and icon to a ListView on our main form
private void CheckRunningapps()
{
    List<Process> AllProcesses = System.Diagnostics.Process.GetProcesses().ToList();

    listViewRunningApps.BeginUpdate();
    listViewRunningApps.Items.Clear();

    foreach (Process process in AllProcesses)
    {
        ListViewItem lvi = new ListViewItem();
        if (process.ProcessName.ToLower().Contains("marinaoffice"))
        {
            lvi = new ListViewItem("MarinaOffice");
            lvi.SubItems.Add("MarinaOffice");
            lvi.ImageIndex = 1;
            lvi.Tag = process;
            listViewRunningApps.Items.Add(lvi);
        }
    }

    listViewRunningApps.EndUpdate();
}

// Method that actually shows the process.  This works as long as process is minimized
// However, if the process is maximized but, merely behind the current window it does
// not bring it in front.  I have noticed that there is a ShowWindowAsync method.
// Should I use that instead?
private void listViewRunningApps_MouseDoubleClick(object sender, MouseEventArgs e)
{
    ListViewItem lvi = listViewRunningApps.GetItemAt(e.X, e.Y);
    if (lvi != null)
    {
        Process process = (Process)lvi.Tag;
        ShowWindow(process.MainWindowHandle, SW_SHOWMAXIMIZED);
    }
}

尝试这样的事情,我认为发生的事情是,如果窗口已经最大化,则您不会使用 ShowWindow Call 更改窗口状态,在这种情况下,您还需要使用BringWindowToTop将其带到 Z-Order 的前面方法。

Process process = (Process)lvi.Tag; 
ShowWindow(process.MainWindowHandle, SW_SHOWMAXIMIZED);
BringWindowToTop(process.MainWindowHandle);
