我正在尝试将 Visual Studio 6 上完全正常工作的 Win32 代码迁移到 Visual Studio 2010。Rebar 似乎存在一些问题。以下是我在 Visual Studio 6 上运行良好的代码。

HWND            hwndRebar = NULL;
REBARINFO       rbi;
REBARBANDINFO   rbbi;
HWND            hwndChild;
RECT            rc;
LPSTR           lpszTemp;
UINT            nHeight;

hwndRebar = CreateWindowEx( WS_EX_TOOLWINDOW, 
                            REBARCLASSNAME, 
                            NULL,
                            WS_VISIBLE |
                            WS_BORDER | 
                            WS_OVERLAPPED | 
                            WS_CHILD | 
                            WS_CLIPCHILDREN | 
                            WS_CLIPSIBLINGS | 
                            RBS_VARHEIGHT | 
                            RBS_BANDBORDERS | 
                            RBS_DBLCLKTOGGLE |
                            RBS_AUTOSIZE |
                            RBS_REGISTERDROP |
                            CCS_TOP |
                            CCS_NODIVIDER | 
                            CCS_NOPARENTALIGN |
                            0,
                            0, 
                            0, 
                            200, 
                            m_info.cyTB, 
                            hwndParent, 
                            (HMENU)IDC_REBAR, 
                            g_hInst, 
                            NULL);

if(!hwndRebar) 
    return FALSE;

rbi.cbSize  = sizeof(rbi);
rbi.fMask   = RBIM_IMAGELIST;
rbi.himl    = NULL;
if(!SendMessage(hwndRebar, RB_SETBARINFO, 0, (LPARAM)&rbi))
    return FALSE;

//add a band that contains a button
hwndChild = CreateMainToolbar(hwndRebar);

if(!hwndChild)
    return FALSE;

GetClientRect(hwndChild, &rc);

ZeroMemory(&rbbi, sizeof(rbbi));
rbbi.cbSize       = sizeof(REBARBANDINFO);
rbbi.fMask        = RBBIM_SIZE | 
                        RBBIM_CHILD | 
                        RBBIM_CHILDSIZE | 
                        RBBIM_ID | 
                        RBBIM_STYLE | 
                        0;
rbbi.cxMinChild   = rc.right;
rbbi.cyMinChild   = MYICON_CY + EXTRA_PIXELS;
rbbi.cyMaxChild   = TallestBtn(hwndChild);
rbbi.cyChild      = m_info.fTextLabels ? rbbi.cyMaxChild : rbbi.cyMinChild;
rbbi.cyIntegral   = rbbi.cyMaxChild - rbbi.cyMinChild;
rbbi.cx           = 100;
rbbi.fStyle       = RBBS_CHILDEDGE | 
                        RBBS_VARIABLEHEIGHT |
                        ((m_info.windows & WND_TOOLBAR) ? 0 : RBBS_HIDDEN) | 
                        0;
rbbi.wID          = IDC_TOOLBAR;
rbbi.hwndChild    = hwndChild;

// SendMessage FAILED on visual studio 2010. But worked on visual studio 6.
if(!SendMessage(hwndRebar, RB_INSERTBAND, (WPARAM)-1, (LPARAM)(LPREBARBANDINFO)&rbbi))
{
    int i = GetLastError(); // --> i = 6 (invalid handle)
    return FALSE;
}

我尝试在 Visual Studio 6 和 2010 中运行代码并进行一些比较。我发现在视觉 6 上,sizeof(REBARBANDINFO)的值是80而在视觉工作室 2010 上它是100。所以我确实在visual studio 2010上通过硬编码值尝试了一个实验到80。然后sendMessage成功了,但是那个钢筋里面的UI在窗口上是不可见的。谁能帮我解决这个问题?先感谢您。

编辑:

如果我用REBARBANDINFOW_V6_SIZE而不是硬编码值 80替换sizeof(REBARBANDINFO)是个好主意吗?
