[問題] form1控制form2的物件問題

[deh3215 (黑金屬魂)]

專案是用C++,不過大同小異
form1
-----------------------------
#include "form2.h"

public: Form2 ^form2;

private: System::Void btn1_Click(System::Object^  sender, System::EventArgs^
 e) {

         form2 = gcnew Form2();
         form2->Show();
         this->Hide();//隱藏form1
}

form2
-----------------------------
無法inlcude"form1.h"
改成
ref class Form1;
public ref class Form2 : public System::Windows::Forms::Form
{
...
}
public: Form1 ^form1;

private: System::Void button1_Click(System::Object^  sender,
System::EventArgs^  e) {

   form1 = gcnew Form1();//這一行過不了編譯...
   form1>button1->Text = "****";

}

目前想達成功能為form1的button click後,開啟form2,from1隱藏,form2的button按下,

關閉form2,回到form1

問題:已經可以在form2.h宣告form1變數,為何new form1實體就失敗?

還是只能透過傳form1的參考給form2,用public的form1來接?
