加载BMP背景后的CStatic如何绘制文字

Question

  CStatic* pStatic = (CStatic*)GetDlgItem(IDC_STATIC_TEXT);
ASSERT(pStatic);
pStatic->MoveWindow(0,0,200,200,TRUE);
CDC* pCdc = pStatic->GetDC();            
HBITMAP hbitmap = ::LoadBitmap(AfxGetInstanceHandle(),MAKEINTRESOURCE(IDB_BITMAP1) ); CDC dcMem;
dcMem.CreateCompatibleDC(pCdc);               
dcMem.SetTextColor(RGB(0, 255, 0));            
dcMem.SelectObject(hbitmap);         int nHeight = dcMem.DrawText( _T("dadasdasdsa"), &CRect(0,0,240,268),DT_WORDBREAK|DT_EDITCONTROL);
if (!nHeight)
{
TRACE(_T("Error Code:%d\n"),GetLastError() );
} pStatic->ModifyStyle(0,SS_BITMAP);
pStatic->SetBitmap(hbitmap);    有图片无文字，nHeight 不为0，请教。。

Answer 1

你这个bitmap本来就没画上文字

Answer 2

 HBITMAP hbitmap = ::LoadBitmap(AfxGetInstanceHandle(),MAKEINTRESOURCE(IDB_BITMAP1) );    CDC dcMem;
    dcMem.CreateCompatibleDC(pCdc);               
    dcMem.SetTextColor(RGB(0, 255, 0));            
    HBITMAP old = (HBITMAP)dcMem.SelectObject(hbitmap);
         int nHeight = dcMem.DrawText( _T("dadasdasdsa"), &CRect(0,0,240,268),DT_WORDBREAK|DT_EDITCONTROL);
    if (!nHeight)   hBitmap = (HBITMAP)dcMem.SelectObject(old);    {
        TRACE(_T("Error Code:%d\n"),GetLastError() );
    }    pStatic->ModifyStyle(0,SS_BITMAP);
    pStatic->SetBitmap(hbitmap);    
试试

Answer 3

把你绘图的代码放到OnPaint函数中去做~

Answer 4

dcMem.DrawText确定是画上文字了吗？

Answer 5

另外我那个代码的位置放错了，哈哈应该是下面这样的
 hBitmap = (HBITMAP)dcMem.SelectObject(old); 
  if(!Height)
 {
  TRACE(_T("Error Code:%d\n"),GetLastError() );
  }  pStatic->ModifyStyle(0,SS_BITMAP);
  pStatic->SetBitmap(hbitmap); 
不知道楼主是不是直接复制的呢

Answer 6

背景都没了，我把代码放在if (IsIconic())的else子句里

Answer 7

影响很大，换位置导致Height为0时才执行哈

Answer 8

CStatic* pStatic = (CStatic*)GetDlgItem(IDC_STATIC_TEXT);
    ASSERT(pStatic);
    pStatic->MoveWindow(0,0,200,200,TRUE);
    CDC* pCdc = pStatic->GetDC();            
    HBITMAP hbitmap = ::LoadBitmap(AfxGetInstanceHandle(),MAKEINTRESOURCE(IDB_BITMAP1) );    CDC dcMem;
    dcMem.CreateCompatibleDC(pCdc);               
    dcMem.SetTextColor(RGB(0, 255, 0));            
    dcMem.SelectObject(hbitmap);         int nHeight = dcMem.DrawText( _T("dadasdasdsa"), &CRect(0,0,240,268),DT_WORDBREAK|DT_EDITCONTROL);
    if (!nHeight)
    {
        TRACE(_T("Error Code:%d\n"),GetLastError() );
    }
    
    pStatic->ModifyStyle(0,SS_BITMAP);
    pStatic->SetBitmap((BITMAP)dcMem.SelectObject(hBitmap));
