Chat Client Programming

Hello,

I’m planning to build a website using ASP.net. The members of this site should use a client like Skype. The client should support the following features:

·Audio Chat.
·Text chat and instant messaging.
·Desktop sharing

I do not know the best option to achieve that. Is there an existing library to develop this client? Or I should build the client from scratch? Shall I use SIP, XMPP or other protocols? Can I use Google for work or office 365?

Note: The expected number of users is 100’000 and later in future.

Thanks in advance

If you want a custom solution have a look at the SignalR framework.

Desktop sharing can be extremely sketchy (you're potentially sending IO command and control over public networks and have a serious possibility of breaking Confidentiality and Integrity) and unless you have a full Dev/QA team is completely not worth developing in any serious way.

Adobe connect does everything you're talking about and already scales; I'm sure there are other options out there as well.

Controls you create yourself are not automatically remembered, you have to re-add them on page_load or page_init.

You have to re-add the control on Page_Load so that you can access its data.

Good Day All

i have a repeater control that i bind with 10 000 records and it handles it nicely and its defined like this

ASP.NET

<table id="example" class="table table-striped table-bordered" cellspacing="0" width="100%">

                <thead>
                    <tr>
                        <th>ID</th>
                        <th>Recipient</th>
                        <th>Possible Bank</th>
                        <th>Amount</th>
                        <th></th>
                    </tr>
                </thead>
                <tbody>
                    <asp:Repeater ID="rptDonationList" runat="server" OnItemCommand="rptDonationList_ItemCommand">
                        <ItemTemplate>
                            <tr>
                                <td style="width: 10%">
                                    <%# Eval("DONATIONS_ID") %>
                                </td>
                                <td style="width: 30%">
                                    <%# Eval("Name") %>
                                </td>
                                <td style="width: 30%">
                                    <%# Eval("LU_BANKS_NAME") %>
                                </td>
                                <td style="width: 20%">R <%#string.Format("{0:n}",Eval("AMOUNT")).Replace(".00","") %>  
                                </td>
                                <td style="width: 10%">
                                    <asp:Button ID="btnDonate" Width="70" Height="29" CommandArgument='<%# Eval("AMOUNT") +"|"+Eval("RECEPIENT_USER_ID")+"|"+Eval("DONATIONS_ID")+"|"+Eval("RemainingDonationAmount") %>' CommandName="Donate" CausesValidation="false" runat="server" CssClass="btnred  btn-danger" Text="Donate" /></td>
                            </tr>
                        </ItemTemplate>
                    </asp:Repeater>

                </tbody>
            </table>

When the Button Donate is clicked it fires the OnItemCommand event that is defined like this

<br />
 protected void rptDonationList_ItemCommand(object source, RepeaterCommandEventArgs e)
        {
            if (e.CommandName == "Donate")
            {
                 string[] data = e.CommandArgument.ToString().Split('|');
                Session["PaymentAmount"] = data[0];
                Session["PaymentforUserId"] = data[1];
                Session["DonationId"] = data[2];
                Session["RemainingDonationAmount"] = data[3]; 
                Response.Redirect("/MakePayment.aspx",false); 
            }
        }

The problem is when this above event is fired , the page at the bottom left corner shows a message on the status bar "Uploading 10%.." which makes the page to wait until 100% before it moves to another page. What exactly is it uploading as the code above just redirects to the next page.

Thanks

10,000 records on one page?! Do you seriously think anyone is going to look through that many records to find the one they want? WTF | :WTF:

If a user can look at and discard one record every second, it would take them almost three hours to look through your list. And that's assuming they don't make a mistake, miss the record they're looking for, and have to start again.

Also, since you're using WebForms, you're going to have an enormous ViewState, which is almost certainly why your page takes so long to load and to post back.

Split the data into pages of a reasonable size, and give the user tools to filter the list to find the record they want.

Hi Richard

Thanks for your reply. There is paging on the repeater and there is no perfomance issue on the repeater. The only thing that im asking is why does it say "Uploading..." where else in the itemcommand im just assigning some sessions and redirecting?

What i must also mention is that locally connected the online domain it has no issue.

1. Does the 'upload' happening before, or after the event raised? I think you do not hit the server side until the 'upload' is at 100%, so it somehow related to the postback...
2. Put a sniffer (Fiddler like) to see what actually passing on the lines...
3. how large the ViewState is?
4. It is browser specific? What browser?

The Problem has been resolved. This is a good lesson. The problem was that my web application was running in an https IIS server in which my application was using Bootstrap that has fonts which was outside my server with a http not https control. i removed and copied all the files to the local server. So it looked like the system was slow but it was not , there was no error it was just blocking the user from moving forward. i hope this helps someone else

Are you saying that mixed content (http/https) was blocking the pages? Browser should have to show a warning about that...
In any case the solution is to create protocol-less links (using cdn is a good thing and in most cases better than local copy)...

hi experts.. How to use store procedure with Entity Framework

2-May-16 8:58

Yes i was even shocked when i saw this. The thing the page itself does not timeout or give an error the chrome developer toolbar showed me that the page is blocked due to the mixed content. After moving them locally it started moving like lightning fast.
