【问题描述】:
我正在尝试从 Windows 任务管理器中恢复一些项目。 使用此代码,我从 Process TAB 恢复了 SysListView32 句柄: (dlgItem)
IntPtr mainWindowHandle = Process.GetProcessesByName("taskmgr")[0].MainWindowHandle;
Api.WindowPlacement lpwndpl = new Api.WindowPlacement();
lpwndpl.length = Marshal.SizeOf((object) lpwndpl);
Api.GetWindowPlacement(mainWindowHandle, ref lpwndpl);
bool flag1 = lpwndpl.showCmd == 1 || lpwndpl.showCmd == 3;
IntPtr dlgItem = Api.GetDlgItem(Api.FindWindowEx(mainWindowHandle, IntPtr.Zero, (string) null, (string) null), 1009);
如何恢复 SysListView32 服务选项卡的句柄?
我正在使用的一些 API 定义:
internal static class Api
{
public struct Rect
{
private int left;
private int top;
private int right;
private int bottom;
}
public struct Point
{
private int x;
private int y;
}
public struct WindowPlacement
{
public int length;
public int flags;
public int showCmd;
public Api.Point ptMinPosition;
public Api.Point ptMaxPosition;
public Api.Rect rcNormalPosition;
}
[DllImport("user32.dll")]
[return: MarshalAs(UnmanagedType.Bool)]
public static extern bool GetWindowPlacement(IntPtr hWnd, ref Api.WindowPlacement lpwndpl);
[DllImport("user32.dll")]
public static extern IntPtr GetDlgItem(IntPtr hDlg, int nIDDlgItem);
[DllImport("user32.dll", SetLastError = true)]
public static extern IntPtr FindWindowEx(IntPtr hwndParent, IntPtr hwndChildAfter, string lpszClass, string lpszWindow);
}
