Creating a Windows Forms Control (C++)

trying to run this basic form control example on msdn.

At step 1 of the portion "To add a custom property to a control" we place the ClickAnywhere code in the public section of the class.

First error: "error C2144: syntax error : 'bool' should be preceded by ';'"

Is this syntax correct in C++? (see below)

(removing the ClickAnywhere portion of code, it compiles fine...)

Since you are using Visual Studio .Net 2003, you are using Managed C++, not C++/CLI. There is a significant difference in syntax. For a property, you must use the __property keyword, not the C++/CLI property keyword and its new style.

It should therefore be:

__property bool get_ClickAnywhere() {
    return (label1->Dock == DockStyle::Fill);
}
__property void set_ClickAnywhere(bool value) {
    if (value)
        label1->Dock = DockStyle::Fill;
    else 
        label1->Dock = DockStyle::None;
}

It looks like you are being tripped up by following a guide written for C++/CLI (Visual Studio 2005 and later) while still using Visual Studio 2003.
