Is it possible to split a form class code between .h and .cpp file in C++/CLI like we do with native C++
When I do that I get parse error in the designer view.
Yes you can.
Let the method definition in header, for example the constructor and destructor:
Form1(void);
~Form1();
and create a .cpp file, or just edit an existing : include "formName.h"
(dont forgot namespace), next:
Form1::Form1(void)
{
// ...
}
Form1::~Form1()
{
// ...
}
For events (Click, Load, etc) load the event, keep definition of method in header and put the implementation in source file.
.h:
System::Void Button_Click(System::Object ^sender, System::EventArgs ^e);
.cpp:
Void Button_Click(Object ^sender, EventArgs ^e)
{
MessageBox::Show("Hello, world !");
}
