怎么调试才能知道变量有没有取到值呢?
我在用vs.net   2005   vb.net做一个网站,前台代码中其中有一句: <%=theTitle   %> 怎么调试才能知道这个变量有没有取到值呢?,我直接按F5没有报错,但也没有显示这个变量,搞不清了,各位高手讲讲vs的调试吧,越详越好,要是能远程演示下就更好了,qq:164106387
------解决方案--------------------那就 
 response.write(theTitle) 
 response.end
------解决方案--------------------改成下面这样试试 :   
 If Trim(codestr)  <>   " " Then 
     StrCnn =  "server=localhost;uid=as;pwd=;database=myweb " 
     Cnn = New SqlConnection(StrCnn) 
     Cnn.Open() 
     sql =  "select * from book_info where id= " & Trim(codestr) 
     Cmd = New SqlCommand(sql, Cnn) 
     DataR = Cmd.ExecuteReader 
     If DataR.Read() Then 
         theTitle = DataR( "title ") 
   Response.Write( "theTitle设置了值 ") 
   Response.End()   
         theContent = DataR( "content ") 
         theAuthor = DataR( "author ") 
         theCopyFrom = DataR( "copyfrom ") 
         theAddTime = DataR( "addtime ") 
     Else 
   Response.Write( "theTitle没有设置值 ") 
   Response.End()   
         Cnn.Close() 
         Response.Write( " <font color= 'gray '> 请选择文章! </font>  ") 
         Response.End() 
     End If 
     Cnn.Close() 
 Else 
   Response.Write( "theTitle没有设置值 ") 
   Response.End()   
 End If
