Launching a form from a form
Posted on 2011-03-08
I have an application developed under Microsoft Visual Studio .NET 2003 (Visual C++) with two forms, Form1 and Form2.
When I click a button on Form1 (Button2) I want to hide Form1 and show Form2. But how ?
(Yes, I am a newbie on this topic.. :-( ).
The code generated by MS Visual Studio .NET 2003 (Visual C++) is:
private: System::Void button2_Click(System::Obje
{
// Put some code in here to launch Form2.
}

Form2^ frm = new Form2();
this->Hide();
frm->ShowWindow();
ps. .Net code is not MFC - the two are rather different languages.

When trying to compile this source code I get the following errors:
Form1.h(104) : error C2143: syntax error : missing ';' before '^'
Form1.h(106) : error C2065: 'frm' : undeclared identifier
Form1.h(106) : error C2227: left of '->ShowWindow' must point to class/struct/union
type is ''unknown-type''
C:\Programfiler\Microsoft Visual Studio .NET 2003\Vc7\PlatformSDK\Inclu
What have I done wrong here ? :-(

The following code compiled and run without errors.
Form2 * md1=new Form2();
md1->Activate();
md1->Show();
Form2 * md1=new Form2();
md1->Activate();
md1->Show();
I'm a newbie. I use Microsoft Visual Studio .NET 2003 IDE with Visual C++.
Your code (which of course is C++.net-code) did not compile (see error messages in an earlier posting), but my code snippet did compile and - surprisingly - it runs as well.
I started by choosing "Visual C++ Projects" and then "Windows Forms Application" as template. This template should be "A project for creating an application with a Windows user interface using Managed Extensions for C++.". So maybe I'm not using .NET-code using this template at all - or.. ???

Hmmm, is it using the older syntax? Microsoft made some changes to C++.net very early on. Be careful, you might be writing code that you would have difficulty porting to a newer version of visual studio.
