如何从一种形式回到另一种形式 [英] How to go back from one form to other

问题描述

大家好，

我对C ++/CLI编程是相当陌生的.在我的项目中，我有一个主要形式.当我单击它上的按钮时，我会隐藏此表单并显示其他表单.这很好.我使用的代码是

hi guys,

i am fairly new to c++/cli programming. In my project i have a main form. when i click a button on it i hide this form and show other form. this is working fine. The code i used is

weatherfrm^ weather = gcnew weatherfrm();
this->Hide();
weather->ShowDialog();

现在我想做的是，当我单击第二个表单上的按钮时，我想再次显示第一个表单并关闭此表单.我能够关闭第二种形式，但是我找不到显示第一种形式的方法，因为我无法在第二种形式上创建第一种形式的实例.这样做的原因是，我在第一个中包含第二种形式weather.h，但是现在我不能对主形式做同样的事情，因为文件不能互相包含.


有人可以帮我吗?

now what i want to do is when i click the button on the second form i want to show the first form again and close this form. i am able to close the second form but i cant find a way to show the first form as i cannot create an instance veriable of first form on the second form. The reaon for this is that i include the second form weather.h in the frst one but now i cant do the same for the mainform as the files cannot include each other.


can someone plz help me.

推荐答案

您可以使用方法ShowDialog()显示第二个表单，此调用将显示该表单，直到该表单为关闭.然后，要再次显示主要表单，只需在下面的行中添加this->Show():

You show the second form using the method ShowDialog(), this call show the form and doesn''t return until the form is closed. Then to show again the main form, you have to just add this->Show() on the line below:

weatherfrm^ weather = gcnew weatherfrm();
this->Hide();
weather->ShowDialog();
this->Show();
