I typed up an an aspx page, everthing looked good--it worked, and then suddenly it doens't work anymore.  I get an error:

Description: An error occurred during the compilation of a resource required to service this request. Please review the following specific error details and modify your source code appropriately.

Compiler Error Message: CS1002: ; expected

Line 322:            #line default
Line 323:            #line hidden
Line 324:            parameterContainer.Controls[1].RenderControl(__output);
Line 325:        }
Line 326:        


The Line error isn't in my code. I've looked on the internet and only found something about modifying the code too much so I RETYPED the whole thing again by hand.  Same problem.

Can anyone help?

I don't know but could it be that I user make a SqlParameter for the querystring "categoryID" for 4 command objects because I need it 4 times?

            cmd3.CommandType=CommandType.StoredProcedure;
            cmd3.Parameters.Add("@urlCatID",SqlDbType.Int);
            cmd3.Parameters["@urlCatID"].Value=Request.Querystring["categoryID"];

Hi,
the following error "Compilation Error CS1002: ; expected" will be reported if you have missed ; in any of the lines. Check whether every line ends with a ;

regards,

and also since the parameter is of type int you should also convert it to int like
cmd3.Parameters["@urlCatID"].Value=Convert.ToInt32(Request.Querystring["categoryID"].ToString());

venki

The error line referred to isn't even in my code--it's some hidden thing.  I don't have 324 lines in my code.

I've tried the converting to int but doesn't help--but the error message does seem to refer to a parameter problem....

sounds like .net indexing is having problem.

try this,
1. close all of open vs.net ide
2. restart iis
3. remove all files under %Windir%\Microsoft. net\Framework\v1.1.4322\Temporary ASP.NET Files\ or %Windir%\Microsoft. net\Framework\v1.0.3705\Temporary ASP.NET Files\ if you have ver1.0 installed.
4. remove all files under C:\Documents and Settings\<yourUserName>\VSWebCache\<yourMachineName>

re-open the project / solution and then recompile.

ok, I have the assumption because you were mentioning that the error message was showing something that is not from your code. try one last try before pasting your code here.

Close the ide, remove all files which have .dll, .pdb and .projdata extension. they're usually under folder bin\debug and bin\release or object\debug and object\release for each project.

re-open the solution and then re-compile.

Hi,
"I'm not using VS.net.  I'm hand coding this."
C# is case-sensitive since you are not using vs.net check whether you are using proper cases for keywords.
also can you paste the code here.

Yes I will paste code here.  I'm new to this and I saw the page working perfectly displaying all output then suddenly didn't.
I might have accidentally done something.  Also, because I'm new to this my coding may not be the best.
By the way, the other pages are still displaying nicely with all database outputs happening as they should.

Thanks for taking a look.

Hey, I think it's something wrong with this line--the second thing I'm trying to pass <%CatHeader%> was one of the last things I was working on...
I figure it's this because I just tried to add another querystring and the error was similar but refered to that line...

  <td nowrap bgcolor="#E9EAEB">
        <a href="products.aspx?subCatID=<%#DataBinder.Eval(Container.DataItem,"subCatID")%>&category=<%CatHeader%>" class="h5_roll">

I have a bunch of this kind of code embedding in my aspx, I use c# and never put semicolon behind.
Now the code is running the production without any problem. So I guess that's not the problem.

Hi, no that's not it either but here's  a bit of good news--when I remove any reference to <%=CatName;%> or <%=CatName%> or whatever
and just type in the the querystring, the page shows up fine!

Can someone please look at how I am retrieving the querystring incorrectly at the top:

string CatName=Request.QueryString["Category"];

Thanks

BTW--yes I found all the other typos in the code after removing the  <%=CatName;%> so the page shows but the displaying of
the querystring still gives the same error so I'm pretty sure it's this.

ihenry,

I do have <table></table> tags etc.  remember I'm only providing the User Control portion--not the whole HTML page--just to keep things
shorter.  The page DOES show up nicely when no reference to the <%=CatName;%>--which I believe is THE problem!!

No, that's not the problem either--I even typed it in the address bar to make sure.

I've used this on another part of the page to try to display but it gives the same error that  ) is expected:

<span class="h4_b_666666"><%=CatName;%></span>

Hi,
I think the problem lies here. in your script section you are declaring and initializing CatName variable inside the IsPostBack check like this
<script runat="server">
void Page_Load(object sender, EventArgs e)
{
     if(!IsPostBack){
     
          //string CatID=Request.QueryString["catID"];
          string CatName=Request.QueryString["Category"];

and when you try to access it like this
=<%=CatName;%>"

you will get the following error
Compiler Error Message: CS1026: ) expected

so modify the code block like this

script runat="server">
string CatName;
void Page_Load(object sender, EventArgs e)
{

     if(!IsPostBack){
            
          //string CatID=Request.QueryString["catID"];
           CatName=Request.QueryString["Category"];

and now access the variable like this
<%=CatName %>

It should work

            <form id="Form1" method="post" runat="server">
            <%=CatName %>
            </form>
      </body>
</HTML>

and when I access the webform like this
http://localhost/WebApplication29/WebForm1.aspx?Category=bbb

I got the display bbb

I hope that this helps you

PS- I think when you declare a variable within a {} block it will be accessible from only that block i.e its scope will be limited
to only that block. I think this is what is causing you the problem.

venki,

THANK YOU! That was the problem.

I think I know what you mean about initializing it inside the Page_Load...if I vaguely remember my C# classes.

If you have a brief explanation that would be great too, otherwise thanks to both you and ihenry for your patience with this.
