Changing Dialog like UNIX or LINUX App

When I worked on Unix systems, I thought that the Unix applications were so cool !!
Therefore, I decided to sumbit this article/code that will enable you to
achieve some of the same features regarding the appearance of Windows dialogs that
Unix and LINUX programmers/users have come to know and love. Enjoy!

First of all, create ‘dialog based app’ and insert the following code into your …Dlg.h

class C…Dlg : public CDialog
{
// Construction
public:
CRect m_rcOldRect; // for original window position.

void LargeWindow(); // Recovering original window feature
bool IsSmall;
CDC m_dcSmallIcon; // CDC for smallIcon

….

// Implementation
protected:

afx_msg void OnSmallButton();
afx_msg int OnCreate(LPCREATESTRUCT lpCreateStruct);
afx_msg void OnNcLButtonDblClk(UINT nHitTest, CPoint point);
afx_msg UINT OnNcHitTest(CPoint point);

};

Next insert following code into your …Dlg.cpp

////////////////////////////////////////////////////////////
// Declare Information for ICON.. Global variable!
int ICON_X = 100; // Small Icon position.
int ICON_Y = 400;

int ICON_WIDTH = 32; //Small Icon Width.
int ICON_HEIGHT = 32;

int COUNT = 20;
int TIME = 10;

///////////////////////////////////////////////////////////////
// Code for BEGIN_MESSAGE_MAP
BEGIN_MESSAGE_MAP(CSmallDlg, CDialog)
//{{AFX_MSG_MAP(CSmallDlg)

ON_BN_CLICKED(IDC_SMALL_BUTTON, OnSmallButton)

ON_WM_NCHITTEST()

//}}AFX_MSG_MAP
END_MESSAGE_MAP()

////////////////////////////////////////////////////////////////////////
// Code for OnPaint method..
void C…Dlg::OnPaint()
{
if (IsIconic())
{

}
else if ( IsSmall == true)
{
CWindowDC dc(this);
dc.BitBlt(0, 0 ,32, 32, &m_dcSmallIcon, 0,0,SRCCOPY);

CDialog::OnPaint();
}

….

}
