Practical Learning: Creating a Simple Window

1. To use the dynamic macros, change the file as follows:

#include <afx.h>

#include <afxwin.h>

class CSimpleFrame : public CFrameWnd

{

public:

CSimpleFrame();

DECLARE_DYNCREATE(CSimpleFrame)

#ifdef _DEBUG

virtual void AssertValid() const;

virtual void Dump(CDumpContext& dc) const;

#endif

};

struct CSimpleApp : public CWinApp

{

BOOL InitInstance();

};

IMPLEMENT_DYNCREATE(CSimpleFrame, CFrameWnd)

CSimpleFrame::CSimpleFrame()

{

// Create the window's frame

Create(NULL, "Windows Application");

}

CSimpleApp theApp;

2. Test the application and return to MSVC.

2.2.4 Windows Styles.......................................................................................

Windows styles are characteristics that control such features as its appearance, its

borders, its minimized, its maximized, or its resizing states, etc.

After creating a window, to display it to the user, you can apply the WS_VISIBLE style

to it. Here is an example:

Create(NULL, "Windows Application", WS_VISIBLE);

The top section of a window has a long bar called the title bar. This is a section we

referred to above and saw that it is used to display the name of the window. This bar is

added with the WS_CAPTION value for the style argument. Here is an example:

Create(NULL, "Windows Application", WS_CAPTION);
