Get information from different hidden Form C++/clr - c++-cli

Question

I have a Windows Form application I am creating in C++/CLR Visual Studio 2012.
The goal is to have the user input values into the form named Home Page. Then once all the info is filled in they click a button and the Home Page form is hidden and then second form called Setup Info is shown.
The part I need help with is the info from Home Page needs to be accessible in Setup Info. To get an idea of how my files are setup this is the youtube video I followed to create my C++ Windows Form Application Click Here.
In my HomePage.h
// Button that will hide the Home Page Form and then show the SetupInfo Form.
private: System::Void Start_Click(System::Object^ sender, System::EventArgs^ e) {
this->Hide();
SetupInfo^ SetupInfo = gcnew ExcelToPPT::SeuUpInfo();
SetupInfo->Show();
}
In my Setup Info.H
// When Setup Info is loaded button1 will have the text of textbox1 from Home Page Form.
private: System::Void SetupInfo_Load(System::Object^ sender, System::EventArgs^ e) {
button1->Text = HomePage->Textbox1->Text;
}
This is the general idea but it doesn't work. How do I get this to work?
Let me know if you need any more information.
[EDIT]
I am able to do this through extern global variables, but is there another way to directly access the text text boxes?
Also wen I exit out of my Setup Information it doesn't seem to kill my program how do I solve this problem?

Answer 1

The simplest thing would probably be to just pass your Home Page form to the new SetUpInfo form.
private: System::Void Start_Click(System::Object^ sender, System::EventArgs^ e) {
this->Hide();
SetUpInfo^ setUpInfo = gcnew ExcelToPPT::SetUpInfo(this);
setUpInfo->Show(); ^^^^
}
In SetUpInfo.h:
public ref class SetUpInfo : Form
{
private:
HomePage^ homePage;
public:
SetUpInfo(HomePage^ homePage);
};
In SetUpInfo.cpp:
SetUpInfo::SetUpInfo(HomePage^ homePage)
{
this->homePage = homePage;
}
void SetUpInfo::SetUpInfo_Load(System::Object^ sender, System::EventArgs^ e)
{
button1->Text = this->homePage->Textbox1->Text;
}
