本文介绍了在Windows应用程序中如何使用不同方法来加载和更改光标图标。包括从文件和资源加载光标，根据控件类型或鼠标位置改变光标等实用技巧。

1.从文件加载光标图标

HCURSOR  hcur = ::LoadCursorFromFile(_T("Excalibur.cur"));//加载光标  
	::SetClassLong(GetSafeHwnd(), GCL_HCURSOR, (LONG)hcur);
	return true;

2.从资源加载光标

HCURSOR hCur = LoadCursor(AfxGetInstanceHandle(),MAKEINTRESOURCE(IDC_CURSOR_MOVE));
	::SetCursor(hCur);
//或者SetCursor(AfxGetApp()->LoadCursor(IDC_CURSOR_LINK));
	return true;

3.通过类名，按钮控件改变光标

CString sClassName;
	::GetClassName(pWnd->GetSafeHwnd(), sClassName.GetBuffer(80), 80);
	if (sClassName == "Button")
	{
		HCURSOR hCur = LoadCursor(AfxGetInstanceHandle(),
			MAKEINTRESOURCE(IDC_CURSOR_BT));
		//MAKEINTRESOURCE(IDC_CURSOR1));
		SetCursor(hCur);


	}

4.通过控件ID，按钮控件可以，静态框不行

	/*不可用 CStaic控件的属性Notify 必须要设置为TRUE 才能使得 当鼠标在 CStatic上时改变形状
	if (pWnd->GetDlgCtrlID() == IDC_STATIC_HOME)
	{
		//SetCursor(AfxGetApp()->LoadCursor(IDC_CURSOR_LINK));
		HCURSOR hCur = LoadCursor(AfxGetInstanceHandle(),
			MAKEINTRESOURCE(IDC_CURSOR_LINK));
		SetCursor(hCur);
	}
	*/

5.通过鼠标位置

pt坐标在OnMouseMove获取

void CControlDlg::OnMouseMove(UINT nFlags, CPoint point)
{
	 
	pt= point;


	CControlDlg::OnMouseMove(nFlags, point);
}

BOOL CControlDlg::OnSetCursor(CWnd* pWnd, UINT nHitTest, UINT message)
{
	CRect rect;	
	GetDlgItem(IDC_STATIC_HOME)->GetWindowRect(&rect);
	ScreenToClient(&rect);
	if(HTCLIENT == nHitTest&&rect.PtInRect(pt))	
	{
		//SetCursor(AfxGetApp()->LoadCursor(IDC_CURSOR_LINK));
		HCURSOR hCur = LoadCursor(AfxGetInstanceHandle(),
			MAKEINTRESOURCE(IDC_CURSOR_LINK));
		SetCursor(hCur);
	}


	return TRUE;
	// */
	//return CDialogEx::OnSetCursor(pWnd, nHitTest, message);
}

6.从系统加载

SetCursor(AfxGetApp()->LoadStandardCursor(IDC_HAND));
