Question

如何从方案角度(假设我们称之为变数)提出一种已经显示出来的表象,并将其放在C# WinForms的申请中?

Answer 1

请使用<代码>Bring ToFront()方法

Answer 2

您可使用<代码>SetForegroundWindow。好的例子:。 C# Force Form Focus。

[DllImport("User32")]
private static extern int SetForegroundWindow(IntPtr hwnd);

使用:

SetForegroundWindow(form.Handle);

这里的答案对我来说并不大。如果表格没有重点,使用表格,实际上就把它放在前面。如果形式没有重点,那么活动就只是使形式爆发。我写了这个小的助手,毫无道理地做了工作(我无法得到全部信贷,在为世界森林基金网络找到这个地方,并做了改动):

public static class FormHelper
    {
        const UInt32 SWP_NOSIZE = 0x0001;
        const UInt32 SWP_NOMOVE = 0x0002;
        const UInt32 SWP_SHOWWINDOW = 0x0040;

        [DllImport("user32.dll")]
        private static extern IntPtr GetForegroundWindow();

        [DllImport("user32.dll")]
        public static extern bool SetWindowPos(IntPtr hWnd, IntPtr hWndInsertAfter, int X, int Y, int cx, int cy, uint uFlags);

        [DllImport("User32")]
        private static extern int SetForegroundWindow(IntPtr hwnd);

        [DllImport("user32.dll")]
        private static extern uint GetWindowThreadProcessId(IntPtr hWnd, IntPtr ProcessId);

        [DllImport("user32.dll")]
        private static extern bool AttachThreadInput(uint idAttach, uint idAttachTo, bool fAttach);

        public static void BringToFront(Form form)
        {
            var currentForegroundWindow = GetForegroundWindow();
            var thisWindowThreadId = GetWindowThreadProcessId(form.Handle, IntPtr.Zero);
            var currentForegroundWindowThreadId = GetWindowThreadProcessId(currentForegroundWindow, IntPtr.Zero);
            AttachThreadInput(currentForegroundWindowThreadId, thisWindowThreadId, true);
            SetWindowPos(form.Handle, new IntPtr(0), 0, 0, 0, 0, SWP_NOSIZE | SWP_NOMOVE | SWP_SHOWWINDOW);
            AttachThreadInput(currentForegroundWindowThreadId, thisWindowThreadId, false);
            form.Show();
            form.Activate();
        }
    }

你们都必须做的是表Helper。 Bring ToFront以你想要显示的形式通过。

Answer 4

F或m.Show();

或

F或m.ShowDialog();

What s different? First show new f或m but all other will be activity. Second solution make that only this new f或m will be activity.

Answer 5

您是否尝试了Form.Show(<<><>>>>>>>>和(或 Tom>。
