how to pass value from one form to another?

[The_Sire]

Hi everybody,

i am trying to create a form app with multiple forms. there is a form i'm using as "search". i want to take the value of the textbox in search-form and pass it to another form which shows the result of the search. i've tried to include search-form.h in the form of the result but it returns an error.

	
String ^ key;
key = searchbox->Text;
std::string ks = marshal_as<std::string>(key);
ks=ks+".bin";


	ifstream sfile(ks);
			
        	if (sfile)
		{
                   PatInfo ^ form = gcnew PatInfo;
		   form->ShowDialog();
					
		}												
		else 
			{
 			 MessageBox::Show( "Please try again.");
			}

to conclude, i want the form PatInfo to open an receive the "ks" var. thanks in advance!!
