CListCtrl

图标的原理

a)高宽(x,y)和2个图片句柄
b)图片的句柄有1张彩色，另一张是黑白（Mask）

typedef struct _ICONINFO {
  BOOL    fIcon;
  DWORD   xHotspot;
  DWORD   yHotspot;
  HBITMAP hbmMask;
  HBITMAP hbmColor;
} ICONINFO, *PICONINFO;

CListCtrl列表图标设置

编辑列表项：默认的EditLable
列表项内部数据结构体

 struct LVITEM{
  UINT   mask;
  int    iItem;
  int    iSubItem;
  UINT   state;
  UINT   stateMask;
  LPTSTR pszText;
  int    cchTextMax;
  int    iImage;
  LPARAM lParam;
};

a)插入时可以指定：

int InsertItem(int nItem,LPCTSTR lpszItem,int nImage );

b)修改时指定图标：

BOOL SetItem(    int nItem, 。。。)

列表项组成分析：

int InsertItem(
   const LVITEM* pItem 
);

int InsertItem(
   UINT nMask,
   int nItem,
   LPCTSTR lpszItem,
   UINT nState,
   UINT nStateMask,
   int nImage,
   LPARAM lParam
);

BOOL SetItem( 
   int nItem, 
   int nSubItem, 
   UINT nMask, 
   LPCTSTR lpszItem, 
   int nImage, 
   UINT nState, 
   UINT nStateMask, 
   LPARAM lParam  
); 
BOOL SetItem( 
   const LVITEM* pItem  
); 

CListCtrl-SetItem设置列表项的方法

各种设置方法CListCtrl::SetItemXXX

全部数据设置：CListCtrl::SetItem Sets some or all of a list view item's attributes.

CListCtrl::SetItemCount
 Prepares a list view control for adding a large number of items.
CListCtrl::SetItemCountEx	// Sets the item count for a virtual list view control.

CListCtrl::SetItemData  Sets the item's application-specific value.
 设置关联数据：一个列表项背后可以关联一个结构体，或者一个double或者一个longlong数据。

CListCtrl::SetItemIndexState
 Sets the state of an item in the current list-view control.
CListCtrl::SetItemPosition
 Moves an item to a specified position in a list view control.
 
CListCtrl::SetItemState Changes the state of an item in a list view control.

状态种类有哪些？

#define LVIS_FOCUSED            0x0001  虚线
#define LVIS_SELECTED           0x0002 蓝色

LVITEM lvi = { LVIF_STATE };
	lvi.iItem = 1;
	lvi.state = LVIS_FOCUSED| LVIS_SELECTED;
	lvi.stateMask = LVIS_FOCUSED | LVIS_SELECTED;
	m_list.SetItem(&lvi);
	//等价于 m_list.SetItemState(2, LVIS_SELECTED, LVIS_FOCUSED | LVIS_SELECTED);
CListCtrl::SetItemText  Changes the text of a list view item or subitem.
等价与SetItem 指定{ LVIF_TEXT }
 	LVITEM lvi = { LVIF_TEXT };
	lvi.iItem = 1;
	lvi.iSubItem = 2;
	lvi.pszText = (LPTSTR)(LPCTSTR)str;
	m_list.SetItem(&lvi);

CS架构多页面开发与数据交互

主要有五个窗口 组成
Page1基本信息工号 工资等 对其都采用关联性数据变量 方便操作
Page2 扩展信息 性别 学历等 同样采用关联性数据变量 方便操作
修改窗口 采用Tab Ctrl控件，
数据录入窗口
主窗口

添加用户实现向导多页数据交互
