Referencing TabControls from another Form C++/CLI - c++

Question

I am trying to convert this tabbed browser into C++ from visual basic.
I am trying to reference the Tab Control from Form1.h.
Here is the code on Form1.h:
private: System::Void Form1_Load(System::Object^ sender, System::EventArgs^ e) {
String^ title = String::Concat("TabPage ",(tabControl1->TabCount + 1).ToString());
tab^ newtab = gcnew tab;
newtab->Show();
newtab->TopLevel = false;
newtab->Dock = System::Windows::Forms::DockStyle::Fill;
TabPage^ myTabPage = gcnew TabPage(title);
myTabPage->Controls->Add(newtab);
tabControl1->TabPages->Add(myTabPage);
}
The code on the second form that is trying to create another tab is this:
private: System::Void newTabToolStripMenuItem_Click(System::Object^ sender, System::EventArgs^ e) {
tab^ newtab = gcnew tab;
newtab->Show();
newtab->TopLevel = false;
newtab->Dock = System::Windows::Forms::DockStyle::Fill;
TabPage^ myTabPage = gcnew TabPage();
myTabPage->Controls->Add(newtab);
tabControl1->TabPages->Add(myTabPage);
}
In visual basic all that is required is to add Form1. to the beginning like so...:
//Original
tabControl1.TabPages.Add(myTabPage);
//New
Form1.tabControl1.TabPages.Add(myTabPage);
How could I do this same thing in C++?

Visual Basic provides a default instance of each class in your project. When you say Form1.tabControl1, you're actually getting a particular global instance of Form1, and accessing the tabControl1 field on that.
Add a way to send the instance of Form1 to the second form, and use that instead of Form1. Something simple like passing the instance of Form1 to the second form in its constructor will probably do the trick.
