Anyone get DuplexChannel working over internet?

Posted By:      Posted Date: December 04, 2010    Points: 0   Category :WCF

Starting with P2PCHAT sample in codeproject website, I made a lot of changed to make it working over internet. I find a machine with public IP and run the server (custom resolver) on it, let's call it A. Also I run a peernode on the same machine so that nodes from other machines behind routers can join the same mesh through node A. I dealt with firewall issues as well.

When I get less than 5 (approximately) machines to join the mesh, it's working fine. All 5 people can talk together. However, if more people join in, then no body can see each other anymore. Sometimes 2 or 3 people can still talk to each other while others did not get the messages being sent around.

In the custom resolver, I return the PeerNodeAddress[] with public IPs to the joining nodes.

After months of struggling, I am at wit's end. Can anyone point me to a new direction to give more try? Or sockets would still be more reliable?

Thanks in advance for any suggestions.

CSS font is working in FireFox but not in Internet Explorer 8.0

Hi All, I tried a lot but I could not figure out why the IE is not taking font size and name in to effect from CSS. In firefox my website could be seen very nice but in IE it is little bit unshiny and font size is bigger For the difference which I am talking about could be seen  if your PC have both firefox and IE installed. Please go to http://www.nymidtowndentistry.com open it in FF and IE and you could see the font and alignment related change. All these settings are in body element of CSS. Do you any idea regarding this? Any help would be appreciated. Thanks for your time. -Hitesh

POP up window not working properly in internet explorer


Hi ,

Developing a asp.net c# web site.

I need to open a popup new window when the user clickes a link button.

The following code is written in the click event of the link button.

ScriptManager.RegisterStartupScript(this, typeof(string), "OPEN_WINDOW", "window.open( 'Instructions.aspx', null, 'height=400,width=600,status=yes,toolbar=no,menubar=no,location=no' );", true);

Works fine with firefox. When I try to open this in internet explorer it does not allow to maximise the pop up window ( The maximise is disabled)

I also tried without giving the height and width of the pop up window. But it also failed. Code is as follows.

ScriptManager.RegisterStartupScript(this, typeof(string), "OPEN_WINDOW", "window.open( 'Instructions.aspx', null, 'status=yes,toolbar=no,menubar=no,location=no' );", true);

Any suggestions will be greatly helpful.

Working with SharePoint document libraries

Document libraries are collections of files that you can share with team members on a Web based on Microsoft Windows SharePoint Services. For example, you can create a library of common documents for a project, and team members can use their Web browsers to find the files, read them, and make comments. Users with Microsoft Office 2003 can check out and edit the files as if they resided on a local or network drive.

By default, your team Web site comes with a built-in document library named Shared Documents, which is listed on the Quick Launch bar as well as on the Documents and Lists page.

Server side validation of Fileupload control not working



I've tried this method in my code behind to try and validate that the Fileupload control has a file or not. I get the error message the the event "Server Validate" cannot be found. Can anyone tell why? Thanks.

Public Sub CustomValidator1_ServerValidate(ByVal source As Object, ByVal args As System.Web.UI.WebControls.ServerValidateEventArgs) Handles CustomValidator1.ServerValidate

' Get file name

        Dim uploadAvatar As FileUpload = DirectCast(AdvertisementForm.FindControl("uploadAvatar"), FileUpload)

        Dim UploadFileName As String = uploadAvatar.PostedFile.FileName

        If UploadFileName = "" Then
            ' There is no file selected
            args.IsValid = False

Row command working on all rows not selected one?



I have this code that hides a column in a gridview.  (The column houses another nested gridview).

    Protected Sub GridView1_RowCommand(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewCommandEventArgs) Handles GridView1.RowCommand
        If e.CommandName = "Select" Then
            If GridView1.Columns(0).Visible = False Then
                GridView1.Columns(0).Visible = True
                GridView1.Columns(0).Visible = False
            End If
        End If
    End Sub

The trouble is that if I click the select link on one row that action to hide is carried out on all rows.  How can I set this up so that it only hides the row that is selected?

New off line application working with sdf file. Need advice


Hey Folks

I am working on a project currently where I need to get data out of a 3rd party vendor's software that uses a .sdf file I looked this up and its a SQL CE file. I was hoping to just link to with with access but thats apparently not going to happen. I need to link to the database extract data from it to a csv file for later use. I also and most important I need to get the data from it and create a report that can be printed while on a customers site that my or may not have web access so I need for this program to be on and off line. I had my webapplication that I have been working on open and was able to bring up the sdf file under the server exploere however I can't seem to get anything out of it when I try to do grid views or detail views errors out.

Can I use one of Visual Studio projects to create this sort of applicaiton if so what would be the best approach. I would love to get an access odbc driver since office is allready installed on the employee's laptop's

URL Rewriter.net - not working



I have a website that uses Querystrings to determine what content to show on a page. I would like to be able rewrite these URL's to become Search Engine Friendly URLs. So for example I would like to change http://www.website.co.uk/Company/Company/Conference.aspx?WebPage=ImportantDates to http://www.website.co.uk/Company/Company/Conference.aspx/ImportantDates.

I have been reading the following article by Scott Gu - http://weblogs.asp.net/scottgu/archive/2007/02/26/tip-trick-url-rewriting-with-asp-net.aspx - who suggested using a HTTPModule such as URL Rewriter.net (http://urlrewriter.net/).

So I have done this and added the URLRewriter.dll file in my bin directory and altered the web.config (following Scott Gu's approach #2). However my URL's are not changing and I don't know what I am doing wrong. I have added the following in the web.config to try and change the URL's.


    <rewrite url="~/UKAIS/ConferenceWebPage.aspx?WebPage=(.+)$" to="~/UKAIS/ConferenceWebPage.aspx/$1" />

However my webpage URL remains with the ?WebPage querystring.

I am really stuck and any help would be very much appreciated.
