Question

我遇到以下问题。我非常感谢你的帮助。

问题描述 MFC桌面应用程序 VisualStudio 2010 图标应该在CListCtrl中显示为CImageList。它通常可以正常工作，除非将RemoteDesktop与OS Windows 2008/2003一起使用。在这些特定情况下，图标仅显示为黑色方块。与VMware vSphere连接（RemoteDesktop的替代方案） - ＆gt;图标显示得恰当 Windows XP / 7/8上的Remotdesktop - ＆gt;图标显示正确

代码：

OnInitDialog()
{


    // Setting the symbol for this dialog-field. This is done automatically
    // if the  mainwindow of the application is no dialog-field.
    SetIcon(m_hIcon, TRUE);         // using big symbol
    SetIcon(m_hIcon, FALSE);        // using small symbol

    // TODO: appending additional initialization
    InitList(); //
    m_list.SetImageList(imageList, LVSIL_NORMAL);

    //captions
    CString buf = _T("testitem");   
    m_list.InsertItem(0, buf, 0);
    m_list.SetItemData(0, (DWORD) 0);
    m_list.SetItemText(0, 0, _T("0"));


    m_list.SetItemState(0, 2, LVIS_SELECTED);
    m_list.EnsureVisible(0, FALSE);
}

void CDispomarkierungTestDlg::InitList()
{
    imageList = new CImageList();
    int err = imageList->Create(16, 16, ILC_COLOR32 | ILC_MASK, 1, 1);  //ILC_COLOR16 , ILC_COLOR8 , ... getested 
    int id = 40;
    int requiredLength = 3154;
    LPCSTR picInCharsFromDB = GetBitmapAsText();
    int width = 24;
    int heigth = 24;
    int pixel = 32;
    int planes = 1;
    BYTE *picInBytes = new BYTE[requiredLength];
    int lengthVariable = requiredLength;
    int* lengthPointer;
    lengthPointer = &lengthVariable;

    Base64Decode(picInCharsFromDB, requiredLength, picInBytes, lengthPointer);      

    HANDLE hBitMap = CreateBitmap(width, heigth, planes, pixel, picInBytes);

    BITMAP bitmap;
    GetObject(hBitMap,sizeof(BITMAP),&bitmap);

    CImage image;
    image.Attach((HBITMAP)hBitMap);

    CBitmap icon;
    icon.Attach((HBITMAP)hBitMap);

    CBitmap* bitmappointer;
    bitmappointer = &icon;

    BITMAP bmp;
    icon.GetBitmap(&bmp);

    CClientDC dcClient(this);
    CDC memDC;
    memDC.CreateCompatibleDC(&dcClient);

    HBITMAP hbmMask = ::CreateCompatibleBitmap(memDC.GetSafeHdc(), width, heigth);

    ICONINFO ii = {0};
    ii.fIcon    = TRUE;
    ii.hbmColor = icon;
    ii.hbmMask  = hbmMask;

    HICON hIcon = ::CreateIconIndirect(&ii);
    ::DeleteObject(hbmMask);
    err = imageList->Add(hIcon);
}

在实际应用程序中，源是一个将Bitmap保存为字符串的数据库。这就是加载过程中代码复杂的原因。可以将图像作为资源加载，但在这种情况下没有选项。服务器和客户端的驱动程序更新到最新版本。我在这里添加了项目https://www.hidrive.strato.com/lnk/gRuMg38R。谢谢你帮忙
