我需要一些帮助来调整我的PDF页眉/页脚和我的文本区域.第一页看起来还不错,从那里开始变得更糟.页眉和页脚是否会占用我现有的边距空间？

我想知道出了什么问题以及我可以通过调整来设置以下内容:

1. 页面宽度
2. 边距宽度
3. 头
4. 页脚
5. 文字区域

我的标题覆盖功能如下:

public partial class Header : PdfPageEventHelper
{
public override void OnStartPage(PdfWriter writer, Document doc)
    {
    PdfPTable headerTbl = new PdfPTable(2);
    headerTbl.SetWidths(new float[] { 4, 1 });
    headerTbl.TotalWidth = doc.PageSize.Width;

    iTextSharp.text.Image logo = iTextSharp.text.Image.GetInstance(HttpContext.Current.Server.MapPath("~/Images/view.gif"));
    logo.ScalePercent(5);
    PdfPCell cell = new PdfPCell(logo);
    cell.HorizontalAlignment = Element.ALIGN_RIGHT;
    cell.PaddingRight = 20;
    cell.Border = Rectangle.NO_BORDER;


    Font timesH = new Font(Font.FontFamily.TIMES_ROMAN, 20);
    Font times = new Font(Font.FontFamily.TIMES_ROMAN, 10);
    Chunk c1= new Chunk("THIS IS MY HEADER TEXT", timesH);
    Chunk c = …

我正在使用使用GOOGLE MAPS API v3的 Web应用程序.

我正在画一个poly-line与之相连的东西Google Way Points poly-line.

我希望我的折线具有与其相同的颜色和重量Way Points poly-line.

但我无法弄清楚默认Google方式的蓝色和绿色线的颜色代码和笔画重量是多少？

我有一个表,其中A,B和C允许空值.

SELECT  
   A, B, C, 
   A + B + C AS 'SUM' 
FROM Table

如果我的A, B and C值是10, NULL and NULL,我的SUM列中没有显示任何内容.

有没有办法解决这个问题,并显示SUM为10？除了将NULL转换为零之外？

当执行mysql查询时,它会多次显示记录,尽管数据库中只存在单个条目.为什么会这样？每当我执行查询

SELECT  a.*, 
        b.CNTCT_ADD_ID  AS Cntct_Add_Id,
        c.PHONE_NBR_ID AS Cntct_nbr_Id, 
        d.OA_NM AS OaNm,
        e.HOUSE_NAME AS house,
        e.FLAT_NO AS flat,
        e.HOUSE_NO AS houseno,
        e.ADDRESS_LINE_1 AS Address1,
        e.ADDRESS_LINE_2 AS Address2,
        e.ADDRESS_LINE_3 AS Address3, 
        f.PHONE_NBR AS phneNO
FROM contact_add_phoneno a
LEFT JOIN contact_address b ON a.CNTCT_ADD_ID = b.CNTCT_ADD_ID  
LEFT JOIN contact_phones  c ON a.CNTCT_NBR_ID = c.PHONE_NBR_ID
LEFT JOIN org_accounts d ON a.OA_ID_ORIGINATED = d.OA_ID
LEFT JOIN address_mst e ON e.ADDRESS_ID = b.ADD_ID 
LEFT JOIN phone_nbr_mst f ON f.PHONE_NBR_ID =c.PHONE_NBR_ID 

它显示相同的记录超过2次.

当我添加struts标签时,格式化消失.我该怎么办？

这是我的代码:

    <div class="panel-body" style="background-color:;">

    <div align="center">
        <font size=3> <s:form id="FormAddUser" name="FormAddUser"
                action="AddUser" method="post" class="form-horizontal">
                <div class="row" align="center">
    <div class="col-sm-6">
        <div class="col-sm-4" align="right">
            <label>User ID</label>
        </div>

        <s:textfield name="UserId" class="form-control"></s:textfield>
    </div>
</div>

<div class="row" align="center">
    <div class="col-sm-6">
        <div class="col-sm-4" align="right">

        </div>

            <label>Address</label>
        </div>

        <s:textarea name="Address" class="form-control"></s:textarea>

        </div>

        <s:textfield name="DOB" class="form-control" placeholder="dd/mm/yy"></s:textfield>
