请问怎样根据以下代码写出IE 地址栏上的参数?

[howtofind]

以下是通过获取IE 地址栏上的参数来把一幅图片按照参数的height,width来显示的,请问应该怎样在IE 地址栏上写,例如我想显示http://localhost/bb/ww.jpg,以下的代码所在地址是http://localhost/bb/default.aspx ,应该怎样写? 谢谢了.


<%@ import namespace="System" %>
<%@ import namespace="System.Drawing" %>
<%@ import namespace="System.Drawing.Imaging" %>
<%@ import namespace="System.IO" %>
<script runat="server" language="VB">
Sub sendFile()
dim g as System.Drawing.Image = System.Drawing.Image.FromFile(server.mappath(request("src")))
dim thisFormat=g.rawformat
dim imgOutput as New Bitmap(g, cint(request("width")), cint(request("height")))
if thisformat.equals(system.drawing.imaging.imageformat.Gif) then
response.contenttype="image/gif"
else
response.contenttype="image/jpeg"
end if
imgOutput.save(response.outputstream, thisformat)
g.dispose()
imgOutput.dispose()
end sub

Sub sendError()
dim imgOutput as New bitmap(120, 120, pixelformat.format24bpprgb)
dim g as graphics = graphics.fromimage(imgOutput)
g.clear(color.yellow)
g.drawString("错误！", New font("黑体",14,fontstyle.bold),systembrushes.windowtext, New pointF(2,2))
response.contenttype="image/gif"
imgOutput.save(response.outputstream, imageformat.gif)
g.dispose()
imgOutput.dispose()
end sub
</script>

<%
response.clear
if request("src")="" or request("height")="" or request("width")="" then
call sendError()
else
if file.exists(server.mappath(request("src"))) then
call sendFile()
else
call sendError()
end if
end if
response.end
%>
