Visual C++ Form Variable Errors - forms

Question

I'm new to Visual C++, have added a form to my project, which has given me a file kamisado_board.h with entirely auto-generated code, which I have included at the bottom of this post for reference. I assume this is fine as it was generated by the program.
I've written a separate file, kamisado_main.cpp, and get the following errors upon compiling:
"Error 1 error C2065: 'KamisadoBoard' : undeclared identifier"
"Error 2 error C2146: syntax error : missing ';' before identifier 'form'"
"Error 3 error C2065: 'form' : undeclared identifier"
"Error 4 error C2061: syntax error : identifier 'KamisadoBoard'"
"Error 5 error C2065: 'form' : undeclared identifier"
"Error 6 error C2227: left of '->Show' must point to class/struct/union/generic type"
I have included the code for this file here:
#include <stdlib.h>
#include <stdio.h>
#include <stdbool.h>
#include <iostream>
#include "kamisado_board.h"
int
main(int argc, char *argv[])
{
bool running = true;
int input = 0;
KamisadoBoard form = gcnew KamisadoBoard;
return(0);
}
I figured that it might be a missing #include from my experience with C (I code C for my job but am new to C++), but it's still complaining even with me including kamisado_board.h. Am I missing a line somewhere? I've included the auto-generated form file kamisado_board.h below for reference though I'm assuming this will be correct! Thanks in advance.

Ok, I'm assuming that the kamisado_main.h is your main form, because you have the main routine in the .c++ file.
I cant't see the whole header file, but I think it looks fine, I hope you created the project with the CLI option.
You have to create the form variable like this, you*re missing ^, this should resolve all the errors: KamisadoBoard ^ form = gcnew KamisadoBoard;
I'm not sure if you can use this native main routine for C++/CLI, if it doesn't work try using this code in your kamisado_main.cpp:
#include "kamisado_main.h"
using namespace Project1;
[STAThreadAttribute]
int main(cli::array<System::String ^> ^args)
{
// Enabling Windows XP visual effects before any controls are created
Application::EnableVisualStyles();
Application::SetCompatibleTextRenderingDefault(false);
// Create the main window and run it
Application::Run(gcnew KamisadoBoard ());
return 0;
}
