C＃隐藏在启动新业态 [英] C# Hide new Form at start

问题描述

IHAVE一种形式，是隐藏的，这个加载子窗体的2E形式应该被隐藏藏汉

请注意事项：我最不使用

  ShowInTaskbar = FALSE; //应该被隐藏得
  

和我最能如果我使用形式之间的通信（隐藏/可见），我不能，直到它的可见=真正的交流;

  this.SetParameterValueCallback + =新SetParameterValueDelegate（ShowMain.SetParamValueCallbackFn）; 
 ShowMain.AddItemCallback =新AddItemDelegate（this.AddItemCallbackFn）; 
 //Showsub.Show（）; 
 Showsub.Hide（）; //没有工作
  

我已经试过到目前为止

  THIS.VISIBLE = FALSE; //没有工作
 
的BeginInvoke（新MethodInvoker（代表
 {
隐藏（）; 
}））; //没有工作
 
 base.SetVisibleCore（假）; //没有工作，我不是能形式
之间进行通信 

解决方案

我真的不明白，为什么你就可以使它在一个工作，而不是其他。从得到时可见它的Show（）方法被调用防止表单需要重写SetVisibleCore方法。也许你可以利用此代码：

 私人布尔mAllowVisible = FALSE; 
 
公共BOOL ReallyVisible {
 {返回mAllowVisible; } 
集合{
 mAllowVisible =价值; 
如果（值）THIS.VISIBLE = TRUE; 
} 
} 
 
保护覆盖无效SetVisibleCore（布尔值）{
如果（价值和放大器;&安培;！IsHandleCreated）CreateHandle（）; //确保Load事件运行
如果值= FALSE（ReallyVisible！）; 
 base.SetVisibleCore（值）; 
} 
  

Ihave a form which is hidden and this loads a subform the 2e form should be hidden aswell

Please notes: I most not use

ShowInTaskbar = false; //  should be hidden too

and I most be able to communicate between forms if I use (hide/visible) i cant communicate until its visible = true;

  this.SetParameterValueCallback += new SetParameterValueDelegate(ShowMain.SetParamValueCallbackFn);
        ShowMain.AddItemCallback = new AddItemDelegate(this.AddItemCallbackFn);
        //Showsub.Show();
        Showsub.Hide(); // not working

I have tried so far

this.Visible = false; // didnt work

 BeginInvoke(new MethodInvoker(delegate
            {
                Hide();
            })); // didnt work

base.SetVisibleCore(false); // didnt work, Im not able communicate between form

解决方案

I don't really understand why you would be able to make it work in one but not the other. Preventing a form from getting visible when its Show() method is called requires overriding the SetVisibleCore method. Perhaps you can leverage this code:

private bool mAllowVisible = false;

public bool ReallyVisible {
  get { return mAllowVisible; }
  set {
    mAllowVisible = value;
    if (value) this.Visible = true;
  }
}

protected override void SetVisibleCore(bool value) {
  if (value && !IsHandleCreated) CreateHandle();  // Ensure Load event runs
  if (!ReallyVisible) value = false;
  base.SetVisibleCore(value);
}
