How do I run Form2, from Form1 ?
in [Visual C]

From: Keith on 26 Apr 2010 20:34 Thanks very much for continuing to answer my questions. I tried a couple of options and included the following two lines... #include "Form1.h" #include <Form2.h> // also tried.... #include "Form2.h" and both ended up with the same error. I must have something else wrong. Keith

If so, use full namespace qualifier when using Form2 class. like Form2Namespace::Form2^ form2 = gcnew Form2Namespace::Form2; or add using Form2Namespace; Form2^ = gcnew Form2;
From: Keith on 27 Apr 2010 22:12 Thank you for your comments and thank you for continuing to help. I built this application to try to learn more about C++ so, least for me, it's become a bit of an interesting quest that's telling me a lot about how C++ works. Over in Form2.h… I have the following code… namespace Test_Forms_Application { /// <summary> /// Summary for Form2 /// /// the machine-generated warning text is here… /// /// </summary> public ref class Form2 : public System::Windows::Forms::Form { public: . . . etc… The same text is in Form1.h where one of the lines is … namespace Test_Forms_Application { with code for Form1 below that. So I tried both of the following code items in the Onclick method for the button in private: System::Void button3_Click(System::Object^ sender, System::EventArgs^ e) { /* // test code A using Test_Forms_Application; Form2^ pForm2 = gcnew Form2(); pForm2->ShowDialog(); // show modal */ // or… // test code B Test_Forms_Application::Form2^ pForm2 = gcnew Form2(); pForm2->ShowDialog(); // show modal } Now the errors are as follows… // error for test code A error C2873: 'Test_Forms_Application' : symbol cannot be used in a using-declaration // error for test code B error C2039: 'Form2' : is not a member of 'Test_Forms_Application' and that just doesn't make sense, so I've clearly made some other error somewhere. When I click on menu shoices … “project”, and then, “show all files” I see tabs in the workspace that show both Form1.h and form2.h. Is it possible that somehow Form2 is not part of the project and I'm clearly not seeing it? Keith

Hi Faisal, I sincerely appreciate your help. I've probably made a mistake that isn't revealing itself yet. I think I'm going to set the problem aside and work on some other areas for awhile ... maybe recreate the whole project to see if this issue continues to exist. I just bought Visual Studio, so it will be a perfect time to recreate it in that new platform after the disks arrive. Thanks so very much. Keith |
