最初无法在窗口中看到列表

Question

我想在单独的窗口中显示列表项。但是，当窗口打开时，它不会显示列表。我可以单击列表项，但看不到它。如果我单击数据，它会一一显示。此外，当我向下滚动列表时，它也会显示数据。

我已经厌倦了

m_bList_index.UpdateData(FALSE); 
m_bList_index.UpdateWindow();
m_bList.UpdateData(FALSE);
m_bList.UpdateWindow();

在DisplayList（）函数的最后，但这不能解决问题。下面是我要编辑的代码。

    CListBox m_bList_index; 
    CMyListBox m_bList; 
    BOOL CBatch::OnInitDialog()
    {
        CDialog::OnInitDialog();
        m_status.Empty();
        m_bIndex.Empty();
        m_elapsed_time.Empty();
        m_estimated_time.Empty();
        CenterWindow();
        m_bList.CreateColumn();
        DisplayList();
        return TRUE;
        // return TRUE  unless you set the focus to a control
    }

    void CBatch::DisplayList()
    {
        unsigned int size;  
        m_bList_title.ResetContent(); 
        m_bList_title.SetHorizontalExtent(2000);
        m_bList_title.InsertString(0, theApp.m_pFieldBTitleStr);
        theApp.bCheckList->SetSortingType(theApp.checkList->GetSortingType());
        theApp.bCheckList->Sort();
        size = theApp.bCheckList->GetSize();            
        m_bList_index.SetRedraw(FALSE);   
        m_bList_index.ResetContent();
        m_bList_index.SetHorizontalExtent(2000);
        m_bList.SetRedraw(FALSE);   
        m_bList.DeleteAllItems();
        m_bList.SetHorizontalExtent(2000);

char ColumnName[256];
char strColumnValue[256];
double fColumnValue;

for (unsigned int i = 0; i < size; i++)
{      
    char buffer[255];
    int index = 0;

    if(m_bList.m_SerialNo)
    {
        sprintf(buffer,"%d",i+1);
        m_bList.InsertItem(i, buffer,0);
        index = 0;
    }
    else
    {
        theApp.bCheckList->m_checkArray[i]->get((CV_CHECK_FIELD)(m_bList.ListColumns[0]),buffer);
        m_bList.InsertItem(i, buffer,0);
        index = 1;
    }
    for(; index < m_bList.NoofColumns; index++)
    {

        LV_COLUMN rightjust;
        rightjust.mask = LVCF_FMT;
        rightjust.fmt = LVCFMT_RIGHT;
        m_bList.SetColumn(index+m_bList.m_SerialNo,&rightjust);

        memset(buffer,0x0,256);
        theApp.bCheckList->m_checkArray[i]->get((CV_CHECK_FIELD)(m_bList.ListColumns[index]),buffer);

        if ( (m_bList.ListColumns[index] ==  CV_CHECK_FIELD_FILELOCATION) ||
            (m_bList.ListColumns[index] ==  CV_CHECK_FIELD_POSTED_DATE) ||
            (m_bList.ListColumns[index] == CV_CHECK_FIELD_STATUS))
            strcpy(buffer, buffer);
        }

        m_bList.SetItemText(i,index+m_bList.m_SerialNo,buffer); 

    }

}
        m_bList.SetSel(0, TRUE);
        m_bList.SetRedraw(TRUE);
        m_bList_index.SetRedraw(TRUE);
        UpdateData(FALSE);
    }
