Answer 1

CWnd* pWnd=GetDlgItem(IDC_HIDE);                  
CDC*  pDC=pWnd->GetDC();                                 
pWnd->Invalidate();                                      
pWnd->UpdateWindow();                                    
CRect rectBtn;                                                               
pWnd->GetClientRect(&rectBtn); 
pDC->SetBkMode(TRANSPARENT);
CPen penBtn;
penBtn.CreatePen(PS_SOLID, 1, RGB(255, 255, 255));
pOldPenBtn = pDC->SelectObject(&penBtn);
CBrush brushBtn;
brushBtn.CreateSolidBrush(RGB(255, 255, 255));
CBrush *pOldBrushBtn;
pOldBrushBtn = pDC->SelectObject(&brushBtn);
pDC->Rectangle(&rectBtn);
pDC->SelectObject(pOldPenBtn);
pDC->SelectObject(pOldBrushBtn);
pWnd->ReleaseDC(pDC);IDC_HIDE为按钮ID，画圆的话将Rectangle改为Ellipse

在不行的话，就弄个ICO图片，贴上去。
