闪屏等到线程结束 [英] Splash Screen waiting until thread finishes

问题描述

我仍然有闪屏的问题。我不想使用属性 SC.TopMost = TRUE 。

I still have a problem with the splash screen. I don't want to use the property SC.TopMost=true.

现在我的应用场景如下：

Now my application scenario is as follows:

在progeram.cs：

[STAThread]
static void Main()
{
    new SplashScreen(_tempAL);// where _tempAL is an arrayList
    Application.Run(new Form1(_tempAL));
}

在SplashScreen类：

public SplashScreen(ArrayList _Data)
{
    DisplaySplash()
} 
private void DisplaySplash()
{
    this.Show();
    this.TopMost = true;
    this.CenterToScreen();
    this.SetTopLevel(true);

    _allServerNarrators = new string[10];
    for (int i = 0; i < _allServerNarrators.Length; i++)
        _allServerNarrators[i] = null;

    GetFromServer();

    this.Hide();
    _serverData = new ArrayList();
    _thisData.Add(_allServerNarrators);
    _thisData.Add(_serverNarrators);

}
private void GetFromServer()
{
    _serverNarrators = new ArrayList();
    string _file = "Suras.serverNar";

    if (!Directory.Exists("c:\\ASGAQuraan"))
        Directory.CreateDirectory("c:\\ASGAQuraan");

    while (counter < 4 && _serverFiles == null)
    {
        if (Download("c:\\ASGAQuraan", _ftpServerIP, _file))
        {
            StreamReader _strReader = new StreamReader
                         ("c:\\ASGAQuraan\\"+_file,System.Text.Encoding.Default);
            string _line = _strReader.ReadLine();
            string _word;

            while (true)
            {
                while (_line != null)
                {
                    _word = _line.Substring(0, _line.IndexOf("*"));
                    int _narId = Convert.ToInt32(_word);
                    _line = _line.Substring(2);
                    int k = 0;
                    _serverNarratorNode = new ArrayList();
                    while (true)
                    {
                        int ind = _line.IndexOf("*");
                        if (ind > 0 && ind < _line.Length)
                        {
                            string str = _line.Substring(0, (ind));
                            if (k == 0)
                            {
                                _allServerNarrators[_narId] = str;
                                _serverNarratorNode.Add(str);
                            }
                            else
                            {
                                _serverNarratorNode.Add(str);
                            }
                            _line = _line.Substring(ind + 1);
                            k++;
                        }
                        else
                        {
                            _line = null;
                            break;
                        }
                    }
                    _serverNarrators.Add(_serverNarratorNode);
                    _serverFiles = "added";
                }
                _line = _strReader.ReadLine();
                if (_line == null)
                {
                    break;
                }
            }
        }
        else
            counter++;
    }
}

我要的东西在其中等待，直到线程完成闪屏类。

What I want is something in the splash screen class which waits until the thread finishes.

有关详细信息，请告诉我，我要告诉你。

For more details, please tell me what I need to tell you.

推荐答案

在2个线程以下是有点混乱，但我要带刺，说这...

Following across 2 threads is a bit confusing, but I'm going to take a stab and say this...

我不完全明白这里你的设计，但如果问题是，当你启动第二个应用程序的启动画面形式变白......这是最有可能的原因在于初始屏幕忙于执行所有这些事实code在GetFromServer（）。这么忙，它没有时间来重新绘制自己。

I don't fully understand your design here, but if the issue is that when you launch a second application the splash screen form turns white... It's most likely due to the fact that splash screen is busy executing all of that code in GetFromServer(). So busy that it has no time to re-paint itself.

您使用 BackgroundWorker组件执行GetFromServer方法。这将运行在独立的线程该方法和离开的形式的螺纹自由地重新油漆本身

To remedy this problem I would suggest that you use the BackGroundWorker component to execute the GetFromServer method. This will run that method in a separate thread and leave the form's thread free to re-paint itself.
