I need to send some data from Form7 to From1.
In Form7 you eneter text in textbox and click button ok
when Form1 load it will show text from Form7 in one lalbel called class_name_lbl..
Here is code for FORM7:

private: String^ class_name()
             {
                
                return textBox1->Text;
             }
private: System::Void button1_Click(System::Object^  sender, System::EventArgs^  e) {
                
                class_name();
             }

Here is code for FORM1

private: System::Void Form1_Load(System::Object^  sender, System::EventArgs^  e) {
            
             Form7^ forma = gcnew Form7();
             forma->ShowDialog();
             class_name_lbl->Text = forma->class_name();
         }

But this code won't work, here is eror in line: " class_name_lbl->Text = forma->class_name();"

and eror is:
"

Error   5   error C3767: 'Klaser::Form7::class_name': candidate function(s) not accessible   d:\maturski\klaser\klaser\Form1.h   1887

"

Can anyone help, and tell me how to solve this eror..?
TNX!
