我使用以下代码显示内部书面公司安全申请的形式方言窗口,其中一项要求是,不能将形式转移、重新布局或以任何其他形式生活。 任何方面,见下面的开端......

public class ShowMessage
{
const int SW_SHOWMAXIMIZED = 3; //for maximising (if desired)
const int SW_SHOW = 5; //for simply activating the form (not needed)
const int SW_SHOWNORMAL = 1; //displays form at original size and position (what we use here)
const UInt32 SWP_NOSIZE = 0x0001; //cannot be resized
const UInt32 SWP_NOMOVE = 0x0002; //cannot be moved
static readonly IntPtr HWND_TOPMOST = new IntPtr(-1); //always lives at the top
const UInt32 TOPMOST_FLAGS = SWP_NOMOVE | SWP_NOSIZE; //sets the flags for no resize / no move
[DllImport("user32.dll")]
static extern bool ShowWindow(IntPtr hWnd, int nCmdShow);
[DllImport("user32.dll")]
static extern bool SetWindowPos(IntPtr hWnd, IntPtr hWndInsertAfter, int X, int Y, int cx, int cy, uint uFlags);
/// <summary>
/// Displays the passed form using the parameters set in the base ShowMessage class
/// </summary>
/// <param name="frm">A Windows Form object</param>
/// <example><code>ShowMessage.ShowTopmost(new myForm());</code></example>
public static void ShowTopmost(Form frm)
{
ShowWindow(frm.Handle, SW_SHOWNORMAL); //shows the form
SetWindowPos(frm.Handle, HWND_TOPMOST, 0, 0, 0, 0, TOPMOST_FLAGS); //sets the form position as topmost, centered
}
}
Then I simply call
ShowMessage.ShowTopmost(new frmMessage());
我不说这是唯一的方式,也不是正确的方式,而是说是:
