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) ...

  • How to avoid displaying of system menu !!

    Posted by Legacy on 12/03/1999 12:00am

    Any solution for this problem ???

    Bye,

    Is there anyway to stop the repaint of all desktop icons ?
    The flicker spoils the effect.
