Question

in my .h I’ve got something like this:

class Cbeckhoff_frontendDlg : public CDialogEx
    {
    // construction
    public:
    Cbeckhoff_frontendDlg(CWnd* pParent = NULL);
    //...
    //this is the member object I want to create
    Modul test;
    };

And my .cpp looks like this:

Cbeckhoff_frontendDlg::Cbeckhoff_frontendDlg(CWnd* pParent /*=NULL*/)
    : CDialogEx(Cbeckhoff_frontendDlg::IDD, pParent)
    {
    //..
    };
    //and should look like this:
    Cbeckhoff_frontendDlg::Cbeckhoff_frontendDlg(CWnd* pParent /*=NULL*/)
    : CDialogEx(Cbeckhoff_frontendDlg::IDD, pParent),test()
    {
    //..
    };

I messed up the former test case I tried to publish here, I’m sorry about that. I guess I don’t quite understand what happens there. I assume Cbeckhoff_frontendDlg starts the parential CDialogEx- constructor, but I want to start my own constructor test aswell. Is that possible?

If Modul has a default constructor and you do not want to use another constructor, the following is already enough:

Cbeckhoff_frontendDlg::Cbeckhoff_frontendDlg(CWnd* pParent /*=NULL*/)
    : CDialogEx(Cbeckhoff_frontendDlg::IDD, pParent) {}

If you want to use another constructor (e.g., one receiving an integer), you could do:

Cbeckhoff_frontendDlg::Cbeckhoff_frontendDlg(CWnd* pParent /*=NULL*/)
    : CDialogEx(Cbeckhoff_frontendDlg::IDD, pParent), test(some_integer) {}

EDIT: As for the semicolons you should not use a semicolon after a method’s body:

class Foo {
    Foo() {
        // ...
    } // <- no semicolon

    void bar() {
        // ...
    } // <- no semicolon
}; // <- at the end of a class you need a semicolon
