I just ran another test in the converter, and it seems that "Handles Me.Load" is causing the problem.

Removing that allowed me to successfully convert one page...

Cheers,

Thank you Imar. Removing the "Handles Me.Load" did it!!! Now, If I could only figure out the Default.aspx.cs error I'm getting:

Code:

Compiler Error Message: CS0136: A local variable named 'drChatRoom' cannot be declared in 
this scope because it would give a different meaning to 'drChatRoom', which is already used 
in a 'parent or current' scope to denote something else

Source Error:

 

Line 23:             DataRow drChatRoom;
Line 24:             int lastCategoryID = 0;
Line 25:             foreach (int drChatRoom in dtChatRoom.Rows)
Line 26:             {
Line 27:                 int CategoryId = dtChatRoom.Rows(currentRow).Item("CatID").ToString();

Line 25 is the one throwing the error. Any takers?

Heuh? I was preparing an answer based on message alerts I got, but now when I wanted to post the answer, the questions are gone ... ;)

I am not sure if I am changing the intention, but this should work:

DataRow drChatRoom;
int lastCategoryID = 0;
foreach (drChatRoom in dtChatRoom.Rows)
{
int CategoryId = dtChatRoom.Rows(currentRow).Item("CatID").ToString ();

(e.g. remove the int datatype for drChatRoom in the loop.)

Or:

int lastCategoryID = 0;
foreach (DataRow in dtChatRoom.Rows)
{
int CategoryId = dtChatRoom.Rows(currentRow).Item("CatID").ToString ();

Besides this, I think

dtChatRoom.Rows(currentRow)

has to be

dtChatRoom.Rows[currentRow]

as it is an indexer, not a method....

Cheers,

Imar

Imar,

Thanks for all the help. I tried your suggestions, but no I get the error:

"CS0230: Type and identifier are both required in a foreach statement"

Ok, so I "gave up" on the previous error, and I worked around it. Now, I get the chat room display but I get the following Javascript error at the bottom of my page:

Line: 16
Char: 5
Error: 'Object expected'
Code: 0
URL: http://domain/ChatWindow.aspx?ChatRoomID=1

My code in ChatWindow.aspx looks like this:

Code:

<%@ Page Language="C#" AutoEventWireup="false" CodeFile="ChatWindow.aspx.cs" Inherits="aftercare_ChatWindow" %>

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

<html xmlns="http://www.w3.org/1999/xhtml" >
<head id="Head1" runat="server">
        <title>Untitled Page</title>

<script type="text/javascript">

setInterval('refreshChatWindow();',2000);

function refreshChatWindow()
{
    CallServer('', null);     
} //This is line #16, where the error is showing
function ReceiveServerData(arg, context)
{
    //send the value to the html control...
    var obj = document.getElementById("divChatWindow");
    obj.innerHTML = arg;
    location.href = "#bottom";
}


    </script>
</head>

    <body title="Chat Window Area" bgcolor="#ffffcc">
        <form id="Form1" method="post" runat="server">
        <div id="divChatWindow"></div>
        </form>
    </body>
</html>

Any help is appreciated.

I think the previous error can be fixed with this:

foreach (DataRow drChatRoom in dtChatRoom.Rows)
{
int CategoryId = dtChatRoom.Rows(currentRow).Item("CatID").ToString ();

The Javascript error seems to be about a missing CallServer function. Shouldn't you add that function, or include a file that contains it?

Found an excellent little VB.NET to C# conversion tool:

http://www.elegancetech.com/CSVB.aspx

might be worth looking into.

Hmm... they only mention Visual Studio 2003 code, that's NET 1.0 and NET 1.1...

I think purchase is waste, there are free tools available online directly on websites. One of them is "Dot Net Taxi".
