hi everyone

i makes an array "CWnd" class and i want to do "CreateEx" for everyone, but just the first "CreateEx" works and for second and next will error and doesn't work.
i also want set different "Parent" for each (from hwnd).
like : Parent of 1st CWnd is "Cmd" and 2nd is "Calculator" and ... .
can you help me?
what's wrong?

the code i use in create function is like below:

void Theme::CreateTheme(CRect rect,CString Text, CWnd *parent,unsigned short int W,unsigned short int H){

	CString className = AfxRegisterWndClass(CS_HREDRAW | CS_VREDRAW | CS_OWNDC, NULL, (HBRUSH)GetStockObject(BLACK_BRUSH), NULL);
	CreateEx(0, _T(className),Text, WS_POPUP | WS_VISIBLE | WS_CLIPSIBLINGS | WS_CLIPCHILDREN, rect, parent, 0);


	Parent = parent;
	cdc=Parent->GetWindowDC();
	w=W;
	h=H;

}

at finally i want to :

Theme t[5];
t[0].CreateTheme(...);
t[1].CreateTheme(...);
t[2].CreateTheme(...);
...

Actually all the Events like "OnPaint" "OnLButtonDown" and ... work except the"OnTimer".
I need to work with "OnTimer" but just this event doesn't work.
can you tell me where the my wrong is?

thanks an advance

i declared and use them like below :

____________________________________________________________

Theme theme1;
theme1.CreateTheme(CRect(-2,-2,-1,-1),_T("Hello"),CWnd::FromHandle(hwndDlg),800,500);


Theme theme2;
theme2.CreateTheme(CRect(-2,-2,-1,-1),_T("Hello"),CWnd::FromHandle(hwndDlg),500,300);

____________________________________________________________

in the object "theme1", all of the events work but in the Object "theme2" the "OnTimer()" event doesn't work , of course others event like "OnLButtonDown" and ... work correctly in "theme2".

and this is the contains of .h :


__________________________________________________________________

class Theme : public CWnd{
private:
	
protected:
	virtual void DoDataExchange(CDataExchange* pDX);	// DDX/DDV support

public:
	CWnd  *Parent;
	CPoint cursor;
	bool drag;
	CString path,imagepath;
	char DialogMove;//0==top to center - 1==center to top - 2==center to down - 3==down to center
	char code,sb;//code = 0=main page - sb=show button=1=ascedung,-1=desceding;
	short int iimage,bstart,bend,//i = index of images-b = index of buttons
	ib;//ib=index of button for clicking and do code
	short int w, h,D;
	float ani_p, ani_max;
	bool ani,mousec;
	CRect WRect,rdesktop;
	CDC *cdc;
	short int lani;
	HWND hwndani;
	Object *Image;
	CRect *Rect;
	bool *BEnable;//enable of buttons-1 = enable
	unsigned char ButtonCount,ImageCount,SysButtonCount;
	bool Created;

	void GotoPage(unsigned char PageNo,unsigned char BStart,unsigned char BEnd);
	void OnLButtonDown();
	void OnLButtonUp();
	void ClearRect(short i,short j,COLORREF color);
	bool IsIn(CPoint point,CRect rect);
	bool IsInRect(CPoint point,CRect rect,CRect Rectangle);
	void Center2Top();
	void Top2Center();
	void Down2Center();
	void Center2Down();
	bool AddImage(unsigned char Index,CString ImagePath,unsigned short int X,short int Y);
	void AddButton(unsigned char Index,CRect rectangle,bool enable);
	void DrawImages(unsigned char alpha,int IImage);
	Theme(unsigned char imagecount,unsigned char buttoncount,unsigned char sysbuttoncount);
	~Theme(void);
	void CreateTheme(CRect rect,CString Text, CWnd *parent,unsigned short int W,unsigned short int H,UINT nID);
	afx_msg void OnPaint();
	afx_msg void OnTimer(UINT nIDEvent);
	
	DECLARE_MESSAGE_MAP()
};

	OnPaint();
