如何一个接一个地加载多个表单？ [英] How to load multiple forms one after another ?
问题描述
我有3个表单，如form1，form2，form3
每个表单将每10秒逐个加载。
请帮忙我出去了。
我尝试了什么：
Program.cs
.........................
静态class program
{
public static RadForm1 RadForm1 = null;
public static RadForm2 RadForm2 = null;
public static RadForm3 RadForm3 = null;
public static int Flag = 0;
///< summary>
///
[STAThread]
static void Main（）
{
Application.EnableVisualStyles（ ）;
Application.SetCompatibleTextRenderingDefault（false）;
线程splashThread =新线程（新的ThreadStart（
）代表
{
RadForm1 = new RadForm1（）;
RadForm1.Size = new System.Drawing.Size（1365,739）;
Application.Run （RadForm1）;
}
））;
splashThread.SetApartmentState（ApartmentState.STA）;
splashThread.Start（）;
RadForm2 =新RadForm2（）;
RadForm2.Size = Screen.PrimaryScreen.WorkingArea.Size;
RadForm2.Load + = new EventHandler（RadForm1_Load）;
Application.Run（RadForm2）;
RadForm3 =新的RadForm3（）;
RadForm3.Size = Screen.PrimaryScreen.WorkingArea.Size;
RadForm3 .Load + = new EventHandler（RadForm2_Load）;
Application.Run（RadForm3）;
}
静态无效RadForm1_Load（对象发送者，EventArgs e）
{
if（ RadForm1 == null）
{
return;
}
RadForm1.Invoke（新动作（RadForm1。关闭））;
RadForm1.Dispose（）;
RadForm1 = null;
}
static void RadForm2_Load （对象发送者，EventArgs e）
{
if（RadForm2 == null）
{
return;
}
RadForm2.Invoke（新动作（RadForm2.Close））;
RadForm2.Dispose（）;
RadForm2 = null;
}
}
和第二种形式...... ..........
public RadForm2（）
{
Initia lizeComponent（）;
Thread.Sleep（5000）;
this.StartPosition = FormStartPosition.CenterScreen;
}
好吧，假设你在winforms开发方面有相当的技巧，这是一个简单的例子，我在大约10分钟内掀起。第一个for显示10秒，然后关闭，此时第二个表单自动打开。
步骤1 - 创建一个新的winforms应用程序（它已经有Form1）。我在表单中添加了一个ok和cancel按钮。但你没必要。
第2步 - 添加新表格（Form2）。
步骤3 - 在program.cs中，将主函数更改为：
[STAThread]
static void Main（）
{
Application.EnableVisualStyles（）;
Application.SetCompatibleTextRenderingDefault（ false ）;
Form1 f1 = new Form1（）;
Application.Run（f1）;
if （f1.DialogResult == DialogResult.OK）
{
Form2 f2 = new Form2（）;
Application.Run（f2）;
f2.Activate（）;
}
}
第4步 - 这是你的Form1代码
public partial < span class =code-keyword> class Form1：Form
{
int dismiss = 10000 ;
int elapsed = 0 ;
定时器计时器;
public Form1（）
{
InitializeComponent（）;
timer = new Timer（）{Interval = 50 ，Enabled = true };
timer.Tick + = timer_Tick;
}
void timer_Tick（ object sender，EventArgs e）
{
逝去+ = timer.Interval;
if （已过去> = dismiss）
{
button1 .PerformClick（）;
}
}
私有 void button2_Click（ object sender，EventArgs e）
{
DialogResult = DialogResult.Cancel;
this .Close（）;
}
private void button1_Click（ object sender，EventArgs e）
{
DialogResult = DialogResult.OK;
this .Close（）;
}
私有 void Form1_FormClosing（ object sender，FormClosingEventArgs e）
{
timer.Enabled = false ;
timer.Dispose（）;
}
}
计时器可能过于精细，但计时器事件最低Windows中的优先级事件，并不保证在繁忙的系统上处理它们。我建议使用另一种技术，但是出于示例的目的，它是合适的。
你应该能够将这段代码移动到你想要的地方：

I have 3 forms like form1,form2,form3
each form will load one by one every 10 seconds .
Please help me out.
What I have tried:
Program.cs
.........................
static class Program
{
public static RadForm1 RadForm1 = null;
public static RadForm2 RadForm2 = null;
public static RadForm3 RadForm3 = null;
public static int Flag = 0;
/// <summary>
///
[STAThread]
static void Main()
{
Application.EnableVisualStyles();
Application.SetCompatibleTextRenderingDefault(false);
Thread splashThread = new Thread(new ThreadStart(
delegate
{
RadForm1 = new RadForm1();
RadForm1.Size = new System.Drawing.Size(1365, 739);
Application.Run(RadForm1);
}
));
splashThread.SetApartmentState(ApartmentState.STA);
splashThread.Start();
RadForm2 = new RadForm2();
RadForm2.Size = Screen.PrimaryScreen.WorkingArea.Size;
RadForm2.Load += new EventHandler(RadForm1_Load);
Application.Run(RadForm2);
RadForm3 = new RadForm3();
RadForm3.Size = Screen.PrimaryScreen.WorkingArea.Size;
RadForm3.Load += new EventHandler(RadForm2_Load);
Application.Run(RadForm3);
}
static void RadForm1_Load(object sender, EventArgs e)
{
if (RadForm1 == null)
{
return;
}
RadForm1.Invoke(new Action(RadForm1.Close));
RadForm1.Dispose();
RadForm1 = null;
}
static void RadForm2_Load(object sender, EventArgs e)
{
if (RadForm2 == null)
{
return;
}
RadForm2.Invoke(new Action(RadForm2.Close));
RadForm2.Dispose();
RadForm2 = null;
}
}
and in second form................
public RadForm2()
{
InitializeComponent();
Thread.Sleep(5000);
this.StartPosition = FormStartPosition.CenterScreen;
}
Well, assuming you're reasonably skilled at winforms development, here's a simple example that I whipped up in about 10 minutes. The first for is displayed for 10 seconds, and then closes, upon which time the 2nd form opens automagically.
Step 1 - Create a new winforms app (it will already have "Form1"). I added an ok and cancel buttons to the form. but you don't have to.
Step 2 - Add a new form ("Form2").
Step 3 - In program.cs, change the main function to look like this:
[STAThread] static void Main() { Application.EnableVisualStyles(); Application.SetCompatibleTextRenderingDefault(false); Form1 f1 = new Form1(); Application.Run(f1); if (f1.DialogResult== DialogResult.OK) { Form2 f2 = new Form2(); Application.Run(f2); f2.Activate(); } }
Step 4 - This is your Form1 code
public partial class Form1:Form { int dismiss = 10000; int elapsed = 0; Timer timer; public Form1() { InitializeComponent(); timer = new Timer(){ Interval = 50, Enabled=true }; timer.Tick += timer_Tick; } void timer_Tick(object sender,EventArgs e) { elapsed += timer.Interval; if (elapsed >= dismiss) { button1.PerformClick(); } } private void button2_Click(object sender,EventArgs e) { DialogResult = DialogResult.Cancel; this.Close(); } private void button1_Click(object sender,EventArgs e) { DialogResult = DialogResult.OK; this.Close(); } private void Form1_FormClosing(object sender,FormClosingEventArgs e) { timer.Enabled = false; timer.Dispose(); } }
The timer might be too granular, but timer events are the lowest priority events in windows, and they are not guaranteed to be handled on a busy system. I would recommend using another technique for this, but for the purposes of example, it's suitable.
You should be able to moify this code to do what you want:
