When you move the function into a cpp file you have to put the class name
in front of it:

void Form1::Status (String ^message)
{
...
}

Otherwise the compiler thinks it is a global function. I.e., not a
member of any class.

It dosen't resolve problem
Error 1 error C2653: 'Form1' : is not a class or namespace name
c:...\projects\header\header\function.h 5

For example if i make header file like this:
#pragma once

void Status (System::String ^message)


{

message = "global function";



} ;

works good. So problem isn't with that.

Problem occurs when I add to this function any command related with
controls on Form.
For example:

/// function.h

#pragma once

void Status (System::String ^message)


{

message = "global function";

this->MessageBox::Show (message);

} ;

errors:
Error 1 error C2673: 'Status' : global functions do not have 'this'
pointers c:\...\header\function.h 8
Error 2 error C2653: 'MessageBox' : is not a class or namespace name
c:\...\header\function.h 8
Error 3 error C2227: left of '->Show' must point to
class/struct/union/generic type c:\..\header\function.h 8

when i remove this-> errors are:

Error 1 error C2653: 'MessageBox' : is not a class or namespace name
c:\..\header\function.h 8
Error 2 error C3861: 'Show': identifier not found c:\..\header\function.h
8

Problem is with pointer this->. I don't know what it can
replace.



MessageBox will be work if add to header file
using namespace System::Windows::Forms;
