How to invoke the control of another class in MFC in one class

Learning Record:

Two classes, one for the main class

1 for: Cckdlg, main class

1 is: HTTPS, used to make HTTPS request to get page status.

The test interface is as follows:

Defining functions in the Cckdlg class

void // for output log information {M_log. SetSel (-1,-1"\ r \ n",1);}

Https class:

#pragma onceclass  Cckdlg;//Integrated Cckdlgclass  https{public:    Https (void);     ~https (void);     void Test (void);};

The HTTPS class calls Functions in the Cckdlg class

void https::test ()

{

// cwnd* pWnd = AfxGetApp ()->getmainwnd (); cckdlg* ck = // get main program handle ck->printf_r (L"Hello words" // get the defined
MessageBoxW (null,l "https", L "https", MB_OK);
}

After Cckdlg, the interface button responds to the event:

void Cckdlg::onbnclickedbutton1 () {    //  Todo:add your control notification handler codehere c5/>new  Https;    Thttps-Test ();}
