Making an Event for Windows Forms Application's Button

[kustrle]

OK, I made two Windows Forms Applications (Look images below)
Step 1: http://img245.imageshack.us/img245/8227/78636770.jpg
Step 2: http://img408.imageshack.us/img408/808/48168956.jpg
Well, as you see at "step 1" there is some text (blured) and the Next button in bottom left corner. I would like to know how to make that when I click Next button it will send me to Step 2? Step 1 application and step 2 application are 2 different projects... Should i merge them together first (how to do this)?

However once again: I want when I click button Next at Step 1 it open me application of Step 2.

I tryed to describe my problem as much as possible... However, since I am not exprert programer I may missed some important things, so fell free to ask here.

Thanks!

Yes, merge them, all you have to do as far as i know is rename the second form to "Form2" and copy it to the first project. Once you've done that, linking them together isn't too hard.

Try that first.

[kustrle]

Well, I think I have merged 'em but I am not really sure if it's all right...
Here is Screen Shot of my project now (it was project for Step 1 before)
When I have First Step tab selected:

When I have Second Step tab selected:

It gets compiled without errors.

So if it's nicely merged now, what to do if I want when I click Next button at step 1 it send me to step 2?

[William Hemsworth]

Looks good to me.

Okay, now at the top up your header file Form1.h, add the code:

#include "Form2.h"

and to hide the current form and open the new one, place this code in the event handler of the Next button on Form1:

Form2 ^secondForm = gcnew Form2();
this->Hide();
secondForm->Show();

Be weary, one of your forms is named form1 and the other Form2, remember C++ is case sensitive.

[kustrle]

Hm, I added #include line to form1.h. Now beggining of code in form1.h looks like

#include "form2.h"
#pragma once

...

But I got no clue what Event Handler is...
That's the code u told me to add into form1 next button's event handler

Form2 ^secondForm = gcnew Form2();
this->Hide();
secondForm->Show();

Could you tell me more exactly in what file and in what place in that file I should copy that code? Or just what event handler is?

[William Hemsworth]

Could you tell me more exactly in what file and in what place in that file I should copy that code? Or just what event handler is?

When you double click your button in designer mode, it takes you to the code that's executed once it's pressed, It would look something like this:

private: System::Void mybutton_Click(System::Object^  sender, System::EventArgs^  e) {
    Form2 ^secondForm = gcnew Form2();
    this->Hide();
    secondForm->Show();
}

[kustrle]

I get those error results

[William Hemsworth]

You're missing two sets of end curly braces, change the end to this:

private: System::Void button1_Click(System::Object^ sender, System::EventArgs^ e) {
                  form2 ^secondForm = gcnew form2();
                  this->Hide();
                  secondForm->Show();
            }
      };
}

Try to keep your formatting tidy, hope this helps.

[kustrle]

End of my form1.h looks like this

private: System::Void button3_Click(System::Object^  sender, System::EventArgs^  e) {
			 }
private: System::Void label1_Click(System::Object^  sender, System::EventArgs^  e) {
		 }

private: System::Void button1_Click(System::Object^  sender, System::EventArgs^  e) {
                 form2 ^secondForm = gcnew form2();
                 this->Hide();
                 secondForm->Show();
            }
      };
}

It compiles nice, without errors. But when I start application, I can click next button as much times as I want and nothing moves - just as before.

[William Hemsworth]

Don't know, if you did everything I said it should have worked.

[kustrle]

Hm, now it works. It automatialy added me one more line of code to end

private: System::Void button1_Click_1(System::Object^  sender, System::EventArgs^  e) {

I also added

form2 ^secondForm = gcnew form2();
                 this->Hide();
                 secondForm->Show();

Under that line so now my end looks like

private: System::Void button1_Click(System::Object^  sender, System::EventArgs^  e) {
                 form2 ^secondForm = gcnew form2();
                 this->Hide();
                 secondForm->Show();
            }
	  private: System::Void button1_Click_1(System::Object^  sender, System::EventArgs^  e) {
form2 ^secondForm = gcnew form2();
                 this->Hide();
                 secondForm->Show();			  
			   }
};
}

Thank you very much! You helped me.

[William Hemsworth]

Glad to see you got it working :icon_lol:
You're welcome.
