Question

VC中用什么函数可以实现光标的移动

麻烦提供一个简短的例子吧
我要做一个简单的文本编辑器
需要光标可以像TXT那样在任意位置做输入删除的那样的操作
注意是VC啊
谢~~~~

Answer 1

BOOL WINAPI SetCursorPos(
__in int X,
__in int Y
);
Parameters
X [in]
int
The new x-coordinate of the cursor, in screen coordinates.

Y [in]
int
The new y-coordinate of the cursor, in screen coordinates.

Return Value
BOOL

Returns nonzero if successful or zero otherwise. To get extended error information, call GetLastError.

// initialize the cursor array
_afxCursors[0] = ::LoadCursor(hInst, MAKEINTRESOURCE(AFX_IDC_TRACKNWSE));
_afxCursors[1] = ::LoadCursor(hInst, MAKEINTRESOURCE(AFX_IDC_TRACKNESW));
_afxCursors[2] = _afxCursors[0];
_afxCursors[3] = _afxCursors[1];
_afxCursors[4] = ::LoadCursor(hInst, MAKEINTRESOURCE(AFX_IDC_TRACKNS));
_afxCursors[5] = ::LoadCursor(hInst, MAKEINTRESOURCE(AFX_IDC_TRACKWE));
_afxCursors[6] = _afxCursors[4];
_afxCursors[7] = _afxCursors[5];
_afxCursors[8] = ::LoadCursor(hInst, MAKEINTRESOURCE(AFX_IDC_TRACK4WAY));
_afxCursors[9] = ::LoadCursor(hInst, MAKEINTRESOURCE(AFX_IDC_MOVE4WAY));

{
// trackers should only be in client area
if (nHitTest != HTCLIENT)
return FALSE;

// convert cursor position to client co-ordinates
CPoint point;
GetCursorPos(&point);
pWnd->ScreenToClient(&point);

// do hittest and normalize hit
int nHandle = HitTestHandles(point);
if (nHandle < 0)
return FALSE;

// need to normalize the hittest such that we get proper cursors
nHandle = NormalizeHit(nHandle);

// handle special case of hitting area between handles
// (logically the same -- handled as a move -- but different cursor)
if (nHandle == hitMiddle && !m_rect.PtInRect(point))
{
// only for trackers with hatchedBorder (ie. in-place resizing)
if (m_nStyle & hatchedBorder)
nHandle = (TrackerHit)9;
}

//ASSERT(nHandle < _countof(_afxCursors));
::SetCursor(_afxCursors[nHandle]);
return TRUE;
}

使用向导，生成单文档或多文档程序，仔细找一下，选择基类时将默认的CView改为CEditView,就可以实现你想要的功能了。

什么狗屁百度呀，把回答A问题的答案放到B问题下面，乱点鸳鸯呀
