Well, I'm not going to recommend using an ActiveX. I would bet that most users aren't admins on their boxes at work, so I guess we're going to have to just assume that if they have an appropriate OS and .Net version, they can run the app.

how about you develop a thin clien on each of client machine and using .NET remoting to call that client(from web server). then render that data as ur desired format.

The whole point is not installing anything on their machine (it's for enterprise users). I'll just tell the boss it can't be done.

The only way to do this, is to have users upload the files, and then your central app controls who gets what. So, you're talking about building a permissions system, which means users need to log in, and then have permission to files assigned to them.

Is it possible to detect the version of .Net that's installed on a client machine over the web? Specifically, I want to see if .Net 3.5 SP1 is installed.

Hi Am trying to make a Socket web application for testing purposes.
I have sorted out how to use the socket appropriately and it seems like working fine.
One thing I did not figure out how to do is:

I use, for example, the following when creating a socket:

<br />
                //create the listening socket...<br />
                m_socListener = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp);<br />
<br />
                IPEndPoint ipLocal = new IPEndPoint(IPAddress.Any, m_Port);<br />
                    //bind to local IP Address...<br />
                    m_socListener.Bind(ipLocal);<br />
                    //start listening...<br />
                    m_socListener.Listen(4);<br />
                    // create the call back for any client connections...<br />
                    m_socListener.BeginAccept(new AsyncCallback(OnClientConnect), null);<br />

I get the data after the Socket strip the ip/tcp headers.
I am interested in that headers, is there a way I can get it?

I just recieved a new PC at work with Visual Studio 2008 and Crystal Reports 2008 installed on it. I can't seem to add a reference in VS for the Crystal Reports and since they didn't install my old version of Crystal on it, none of my applications can buid without errors. How can I reference Crystal 2008 so that I can update my reprots and compile again? Help!

Thanks all for any imput at all...

Problem when loading an aspx page from ascx

tiran_kaskas29-Jun-09 3:05

29-Jun-09 3:05

Dear colleges,
I have run into the following situation:
webpage1.aspx is using UC1.ascx.
UC1.ascx has a button which as a result will redirect to webPage2.aspx

webPage2.aspx uses UC2.ascx. Within UC2.ascx I have a button (Send).
It seems like pressing the button leads to re-launching webPage2 (it's Page_Load method is being called with IsPostBack set to false).

The problem is that re-launching the page will result in a brand new UC2 instance, which will wipe out all information previously stored in it prior to selecting the Send button.

This is the code in webPage2.aspx.cs:

<br />
namespace conversion<br />
{<br />
    public partial class SocketConnectionListPage : System.Web.UI.Page<br />
    {<br />
        protected void Page_Load(object sender, EventArgs e)<br />
        {<br />
            if (!IsPostBack)<br />
            {<br />
                string[] parameters = new string[2];<br />
                parameters[0] = Request.Params["protocol"];<br />
                parameters[1] = Request.Params["port"];<br />
<br />
                SocketConnectionList myAscx = (SocketConnectionList)FindControl("SocketConnectionList1");<br />
                myAscx.SetSocketProperties(parameters);<br />
            }<br />
        }<br />
    }<br />
}<br />

Not sure what the cause of the problem is but I've always tried to avoid doing navigation in user controls. What you could do it have your page subscribe to an event in the user control and when the button is pressed on the user control raise the event and the event handler in the page can do the redirection.

Can you please explain what it does and where I do it?

I have seen the problem even more weird:
I have a webPage1.aspx which has a registered UC1.ascx.

When you click a button on this web page (all is actually UC1 which is loaded by webPage1.aspx), a new UC1.ascx instance is created. It will happen every click, and has nothing to do with browsing from one page to another.

Any clue?

I got confused,
Have you two different pages with two different usercontrols
Or it is just one page with user control that is added at runtime
Please, clarify
Or send a sample code

foreach(Minute m in MyLife)
myExperience++;

tiran_kaskas29-Jun-09 4:27

29-Jun-09 4:27

Ignore what was previously written to avoid confusion.

I am doing a very simple thing: my aspx page is using a user control. Whenever I click a button, it seems like a new user control class instance is created, and hence all settings stored in the first user control instance were obsolete.

Now, in the ascx I put myDataTable variable for stub purposes. I use it to determine if a new SocketConnection user control is created.
It seems like the first time the page is loaded, I see a SocketConnection instance being created.
Then, if you click whatever button in that page, you see another instance of SocketConnection being created (as myDataTable is null).

I need to keep some information, like socket connection objects, in the user control class to be able to show a list of clients currently connected to this server and the messages exchange.

Thanks for your help.

I might not be fully understanding your problem but....

When the page posts back myDataTable will always be null, it doesn't mean a new instance is being created per se, page level variables aren't persisted between posts,you would need to store it somewhere (i.e. session) and repopulate on post back.

What is the value of PostBack in the user control when you click a button?

tiran_kaskas29-Jun-09 5:27

29-Jun-09 5:27

PostBack is false when a button is clicked.

How do I store information in session?
I mean I need to store socket connection objects etc? Any sample?
