[绘图界面库] 求助list view control绘制表格

    TYPE(T_LVCOLUMN) lvc
    TYPE(T_LVITEM) lvi


   character(len=Len("序号")),dimension(3)::header=["序号","姓名","年龄"]
   character(len=4):: pszText



    lret=DlgInit(IDD_test, gdlg)

    if (lret == FALSE) goto 9999
    lret = DlgModeless(gdlg)

    hListView=getDlgItem(gdlg%hwnd,IDC_LISTCONTROL)
    lret= sendmessage(hListView,LVM_SETEXTENDEDLISTVIEWSTYLE,0,LVS_EX_GRIDLINES)

    lvc%mask=IOR(IOR(LVCF_WIDTH,LVCF_TEXT),LVCF_SUBITEM)
    lvc%cx=50

    do i=1,3
        pszText=header(i)
        !      iret = MessageBox(null, pszText, "Error"C, MB_OK)
        lvc%pszText=LOC(pszText)
        lvc%iSubItem=i-1

        lret= sendmessage(hListView,LVM_INSERTCOLUMN,i-1,LOC(lvc))
    end do

！上面的代码可以显示出表头"序号","姓名","年龄"
！下面的代码用来添加项目，程序没有报错，可以没有显示出来任何一个“小明”
    lvi%mask=LVIF_TEXT

    pszText="小明"C
    lvi%pszText   =LOC("小明"C)
    !       lvi%iItem  = sendmessage(hListView,LVM_GETITEMCOUNT,0,0);
    lvi%iItem=0
    lvi%iSubItem  =0;
    lret=sendmessage(hListView,LVM_SETITEM,0,LOC(lvi))

if (lret == -1) then
        goto 9999
    else
        lvi%mask=LVIF_TEXT

        lvi%pszText   =LOC("小明"C)
        lvi%iSubItem  =1;

        lret =sendmessage(hListView,LVM_SETITEMTEXT,1,LOC(lvi))
    end if

    if (lret == -1) then
        goto 9999
    else
        lvi%pszText   =LOC("小明"C)
        lvi%iSubItem  =2;
        lret =sendmessage(hListView,LVM_SETITEMTEXT,2,LOC(lvi))
    end if


    return

9999 iret = MessageBox(null, "Error initializing dlg"C, "Error"C, MB_OK)
    return
