我有一个主窗体，它是不可见的，并且在某些时候会创建一个子窗体。该子窗体在 Designer.cs 中如下所示：
this.listBox1 = new System.Windows.Forms.ListBox();
this.SuspendLayout();
//
// listBox1
//
this.listBox1.FormattingEnabled = true;
//this.listBox1.Location = new System.Drawing.Point(0, 0);
this.listBox1.Name = "listBox1";
this.listBox1.Size = new System.Drawing.Size(255, 147);
this.listBox1.TabIndex = 0;
//
// Form2
//
this.AutoScaleDimensions = new System.Drawing.SizeF(6F, 13F);
this.AutoScaleMode = System.Windows.Forms.AutoScaleMode.Font;
this.AutoSize = true;
this.AutoSizeMode = System.Windows.Forms.AutoSizeMode.GrowAndShrink;
this.ClientSize = new System.Drawing.Size(502, 384);
this.ControlBox = false;
this.Controls.Add(this.listBox1);
this.FormBorderStyle = System.Windows.Forms.FormBorderStyle.None;
this.Name = "Form2";
this.Text = "Form2";
在主窗体中，我正在创建 Form2，如下所示：
Form2 a = new Form2(new Point(0, Screen.PrimaryScreen.WorkingArea.Height / 2)); //This is the location
Thread thtt = new Thread((ThreadStart)delegate()
{
a.CreateControl();
a.Show();
TimeSpan slept = TimeSpan.Zero;
while (!a.Created && slept < TimeSpan.FromMilliseconds(2000))
{
Thread.Sleep(99);
slept += TimeSpan.FromMilliseconds(99);
}
if (!a.Created)
{
MessageBox.Show("after 2 sec no creation?");
System.Diagnostics.Debugger.Break();
}
else
{
//a.Show();
a.Invoke((MethodInvoker)delegate()
{
a.TopMost = true;
a.Location = new Point(0, Screen.PrimaryScreen.WorkingArea.Height / 2);
Cursor.Position = new Point(a.Location.X + 10, a.Location.Y + 10);
a.AddAndAct(minimized);
});
}
aa = a;
});
thtt.IsBackground = true;
thtt.Start();
我遇到的问题是，Form2 实际上是在闪烁，但随后神奇地消失了。任何建议appriciated。
谢谢你的建议，亚历克斯
