Hi guys,

thanks, Wes Aday and Mali_S!

a right way for calling Form2 is:

C#

private: System::Void button1_Click(System::Object^  sender, System::EventArgs^  e) {
                 
                 Form^frm=gcnew Form2();
                 frm->Show(); //Attention: ShowDialog() not the same result
                 Form1::Hide();

}
Of course i've written this above in Form1.h:

C#

#pragma once
#include "Form2.h"

my advanced question is, how can i make this:
Form1 Button_Click->Form2, Form2 Exit->Form1 again!

how can i code the "Quit" top right of the windows??

Thx!

You want to hide the form 1 not close it.

But with "Hide();" there is nothing anymore. Both Form1 and 2 are hidden. I can't see Form2 either...

Form^frm=gcnew Form2(); frm->Show(); Form1::Hide();

Thank you!! it makes sense! what i wrote was Showdialog(), there must have difference.

From two you questions (this and next one) I feel you have a big misconception about using two+ forms. First, you need to explain why doing so, to get a really useful answer. What you are trying to do now it hardly useful...

i just play it for learning. you know, i am a beginner and i am starting with some basic books like Windows Forms Programming with C# etc...

That makes sense. If you do it with experimental purposes, there can be a number of different scenarios of using multiple forms. But in good practice, the best thing is using only one forms. It can have different parts (panels, tabs of a tab control or something like that) which you can show and hide, or re-populate, so those parts would play the roles of different forms.

Solution 1

Instead of closing form1, Hide it. After being done with Form2, close the form1 and exit the function.
