窗口的力量前进

介绍在使用了来自代码项目的代码示例和代码片段那么多时间之后，是时候贡献一些东西了。本文展示了在您自己的项目中使用Form类中的两个预编程属性是多么容易。这说明做这个是多么容易。WindowState这。最上层可以使用。的代码 force forward函数小而简单，调用它时使用bool值强制窗口位于顶部，或者将其重置为正常。如果窗口已最小化到任务栏，则窗口状态将更改为正常状态，因此它将从任务栏弹出。隐藏,复制Code

private void ForceForward(bool forceForward)
{
    if (forceForward)
    {
        // Force the window up from taskbar if needed...
        if (this.WindowState == FormWindowState.Minimized)
            this.WindowState = FormWindowState.Normal;

        // Top most windows...
        this.TopMost = true;
    }

    // If not force forward, set TopMost back
    // to original state...
    else
        this.TopMost = false;
}

序列本程序使用定时器进行演示。当计时器启动时，延迟被设置为5秒。对于计时器每“滴答”一次，延迟就减少1。当延迟达到0(或低于0)时，它执行ForceForward(true)，然后结束序列。隐藏,收缩,复制Code

private void btStart_Click(object sender, EventArgs e)
{
    // Start button set to false!
    btStart.Enabled = false;

    // Run once every second (1000ms = 1sec)...
    timer.Enabled = true;
    timer.Interval = 1000;

    // Delay is set to 5 seconds...
    delay = 5;

    // Show on form in begining of countdown...
    lbCountdown.Text = delay.ToString();
    this.Text = delay.ToString();

    // Start the timer...
    timer.Start();
}

private void timer_Tick(object sender, EventArgs e)
{
    // Decrease delay...
    delay--;

    // Show countdown status...
    lbCountdown.Text = delay.ToString();
    this.Text = delay.ToString();

    // When delay has reached zero, ForceForward...
    if (delay <= 0)
    {
        ForceForward(true);
        EndSequence();
    }
}

private void EndSequence()
{
    // Stop and disable...
    timer.Stop();
    timer.Enabled = false;

    // Reset countdown label...
    lbCountdown.Text = "";
    this.Text = "Force Forward";

    // Start button now enabled for next force...
    btStart.Enabled = true;

    // Now set back to normal... 
    ForceForward(false);
}

当结束序列执行完毕，定时器停止，程序恢复正常;它不再是“最顶层”的窗口。本文转载于：http://www.diyabc.com/frontweb/news11165.html
