我正在使用此代码(在Windows 2003上)删除和调整窗口大小：

Process process = Process.GetProcessById(12121);

IntPtr mwh = process.MainWindowHandle;

SetWindowLong(mwh, GWL_STYLE, WS_VISIBLE);

ShowWindowAsync(mwh, 3);

SetWindowPos(mwh, new IntPtr(0), 0, 0, 0, 0, SWP_NOMOVE | SWP_NOSIZE | SWP_FRAMECHANGED);

和声明：[DllImport(“user32.dll”)] private static extern bool ShowWindowAsync(IntPtr hWnd，int nCmdShow);

[DllImport("USER32.DLL")]

public static extern int SetWindowLong(IntPtr hWnd, int nIndex, int dwNewLong);

[DllImport("user32.dll", CharSet = CharSet.Auto, SetLastError = true, ExactSpelling = true)]

public static extern bool SetWindowPos(IntPtr hWnd, IntPtr hWndInsertAfter, int X, int Y, int cx, int cy, int uFlags);

static readonly int GWL_STYLE = -16;

static readonly int SWP_NOMOVE = 0x2;

static readonly int SWP_NOSIZE = 0x1;

static readonly int SWP_FRAMECHANGED = 0x20;

static readonly int WS_VISIBLE = 0x10000000;

当我调整与我开始的过程相关的窗口时，一切正常 . 但是，当我想与其他用户窗口这样做时，它什么都不做 . 如何让它适用于其他用户的窗口？
