一个窗口不显示在任务栏中，只在系统托盘中。我怎样才能让它显示在任务栏中呢？

我尝试以下code，但它没有任何效果：

  INT windowStyle = GetWindowLong（pMainWindow，GWL_EXSTYLE）;
SetWindowLong函数（pMainWindow，GWL_EXSTYLE，windowStyle和放大器; WS_EX_TOOLWINDOW）;
 

和，这不是我的形式！我碰到Process.GetProcessesByName手柄，我不知道如何访问Form类的属性：

 过程[] =过程Process.GetProcessesByName（somename）;
someProcess =流程[0];

pMainWindow = someProcess.MainWindowHandle;
 

解决方案

下面似乎做的伎俩。如果隐藏＆功放; SetWindowLong函数调用它，然后显示在任务栏后重新出现。该窗口。

我在努力寻找一种方法来从任务栏中移除它曾经窗口是最小化...

  [的DllImport（user32.dll中）
公共静态外部INT的SetWindowLong（IntPtr的的HWND，国际nIndex，INT dwNewLong）;

[的DllImport（user32.dll中）
静态外部布尔的ShowWindow（IntPtr的的HWND，INT的nCmdShow）;

私人const int的SW_HIDE = 0×00;
私人const int的SW_SHOW = 0×05;

私人const int的WS_EX_APPWINDOW = 0x40000;
私人const int的GWL_EXSTYLE = -0x14;

私人无效ShowWindowInTaskbar（IntPtr的pMainWindow）
{
    SetWindowLong函数（pMainWindow，GWL_EXSTYLE，WS_EX_APPWINDOW）;

    的ShowWindow（pMainWindow，SW_HIDE）;
    的ShowWindow（pMainWindow，SW_SHOW）;
}
 

A window is not showing in the task bar, only in the system tray. How can I make it show up in the taskbar as well?

I tried the following code, but it had no effect:

int windowStyle = GetWindowLong(pMainWindow, GWL_EXSTYLE);
SetWindowLong(pMainWindow, GWL_EXSTYLE, windowStyle & WS_EX_TOOLWINDOW);

And, this is NOT my form! I'm getting the handle from Process.GetProcessesByName and I don't know how to access properties of the Form class:

Process[] processes = Process.GetProcessesByName("somename");
someProcess = processes[0];

pMainWindow = someProcess.MainWindowHandle;

The following seems to do the trick. If you hide & reshow the window after calling SetWindowLong it then shows in the taskbar.

I'm struggling to find a way to remove it from the taskbar once the window is minimized...

[DllImport("User32.Dll")]                
public static extern int SetWindowLong(IntPtr hWnd, int nIndex, int dwNewLong);

[DllImport("user32.dll")]
static extern bool ShowWindow(IntPtr hWnd, int nCmdShow);

private const int SW_HIDE = 0x00;
private const int SW_SHOW = 0x05;

private const int WS_EX_APPWINDOW = 0x40000;
private const int GWL_EXSTYLE = -0x14;

private void ShowWindowInTaskbar(IntPtr pMainWindow)
{                       
    SetWindowLong(pMainWindow, GWL_EXSTYLE, WS_EX_APPWINDOW);

    ShowWindow(pMainWindow, SW_HIDE);
    ShowWindow(pMainWindow, SW_SHOW);      
}
