主题：在foxtable中形成了一个字符串，将它存为编码为"UTF-8",后缀为.kml的文件，并起动它，该怎么操作

这个该怎么操作。

另外这个字符串中的长度不受限制，该要定义什么变量

为何出错：

Dim a  As String
a = " <?xml version="1.0" encoding="UTF-8"?>
<kml xmlns="http://earth.google.com/kml/2.2">
<!-- Processed by GE-Path -->
<Document>
<name>New-Path</name>
  <open>1</open>
   <LookAt>
<longitude>2.2</longitude>
<latitude>1.11</latitude>
<range>1000000</range>
<tilt>0</tilt>
<heading>0</heading>
   </LookAt>
   <Style id="sgrillo1">
     <IconStyle>
 <Icon>

<href>root://icons/palette-4.png</href>
         <y>128</y>
<w>32</w>
<h>32</h>
</Icon>
     </IconStyle>
     <LabelStyle>
 <color>ffffffff</color>
        <scale>1</scale>
      </LabelStyle>
   </Style>
<Folder>
  <open>0</open>
 <name>Names</name>
<Placemark>
     <name>dd</name>
   <description>ee</description>
   <styleUrl>#sgrillo1</styleUrl>
   <Point>
   <altitudeMode>clampedToGround</altitudeMode>
      <coordinates>2.2, 1.11</coordinates>
  </Point>
</Placemark>
</Folder>
</Document>
</kml>  "

FileSys.WriteAllText("C:\Documents and Settings\Administrator\桌面\wwffw.kml", a , True,Encoding.UTF8)

对A变量的赋值不成功(这里出错),要如何更改这个代码：

Dim a  As String
a = " .....

.......

......"

FileSys.WriteAllText("C:\Documents and Settings\Administrator\桌面\wwffw.kml", a , True,Encoding.UTF8)

反方向操作又可以：

比如桌面有一个正确的qq.kml文件，我读取这个文件赋值到一个字符变量中，同时又重命名到一个新的*.kml文件，并启动这个*.kml文件，成功，

Dim s As String = FileSys.ReadAllText("C:\Documents and Settings\Administrator\桌面\qq.kml", Encoding.UTF8)
Output.Show(s)
FileSys.WriteAllText("C:\Documents and Settings\Administrator\桌面\aa.kml", s, True, Encoding.UTF8)

所以3楼的代码中的那个字符变量的正确赋值是一个关键,请教大家该如何操作

为什么我把上面代码的前与尾（即下面红色部分），复制贴粘到新代码每一句的前与尾，提示出错，好像还是不能赋值

" <?xml version=""1.0"" encoding=""UTF-8""?>" & vbcrlf & _
"......." & vbcrlf & _

还是不行，附代码：

Dim a  As String
a = "<?xmlversion="1.0"encoding="UTF-8"?>" & vbcrlf & _
"<kmlxmlns="http://earth.google.com/kml/2.2">" & vbcrlf & _
"<!--ProcessedbyGE-Path-->" & vbcrlf & _
"<Document>" & vbcrlf & _
"<name>New-Path</name>" & vbcrlf & _
"<open>1</open>" & vbcrlf & _
"<LookAt>" & vbcrlf & _
"<longitude>2.2</longitude>" & vbcrlf & _
"<latitude>1.11</latitude>" & vbcrlf & _
"<range>1000000</range>" & vbcrlf & _
"<tilt>0</tilt>" & vbcrlf & _
"<heading>0</heading>" & vbcrlf & _
"</LookAt>" & vbcrlf & _
"<Styleid="sgrillo1">" & vbcrlf & _
"<IconStyle>" & vbcrlf & _
"<Icon>" & vbcrlf & _
"<href>root://icons/palette-4.png</href>" & vbcrlf & _
"<y>128</y>" & vbcrlf & _
"<w>32</w>" & vbcrlf & _
"<h>32</h>" & vbcrlf & _
"</Icon>" & vbcrlf & _
"</IconStyle>" & vbcrlf & _
"</kml>"
Output.Show(a)
FileSys.WriteAllText("C:\Documents and Settings\Administrator\桌面\mmmm.kml", a, True, Encoding.UTF8)
