secure sockets in vb.net SriramKS18-May-12 5:33 SriramKS 18-May-12 5:33  I have a client application that connects to a server using sockets. The API published by the company that runs the server states '.. communication is done using SSL-encrypted TCP sockets.' After connecting, I get a connection success. On sending a message, the server reports a 'SSL Handshake failed' error. How do i establish a SSL Handshake? Are there any code snippets available? I am using the Socket Class and not the TCPClient Class to establish connection. Any help in this matter will be highly appreciated.

I've created a pietable from which I build my chart, which has two columns, first column "stockname", second column "stockvalue". I couldn't get the percentages to show up, so I decided to add a third column "percentage" and calculate it there, but then I struggle to show that one in the label. The end result should be that every slice of the pie should show the stockname and the percentage. How to write this in code? Thanks Reference properties not displayed in IDE VS2010 priy@16-May-12 20:02 priy@ 16-May-12 20:02  I have VS2010 SP1 installed on my system. When I open a solution and goto added references, I am unable to view their properties.However I am able to view properties of .cs files. What is the issue here?and how can I resolve it? Re: Reference properties not displayed in IDE VS2010 Dave Kreskowiak17-May-12 2:15 Dave Kreskowiak 17-May-12 2:15  I'm not sure I understand what you're saying, but... If I do, the only properties you could possibly view are the file properties of the referenced library. If that's the case, no, Visual Studio does not show those. Showing those is hardly relevant to anything.

Windows 7 helpfully doesn't provide a way to disassociate file extensions but even so - given I have told the clickonce deployment to associate file extensions I would like it not to ignore me. Anybody any have pointers? I have been googling this all afternoon. Re: Click Once and file associations RugbyLeague16-May-12 6:00 RugbyLeague 16-May-12 6:00  Hmm, it appears it won't overwrite previously set file associations Re: Click Once and file associations Dave Kreskowiak16-May-12 7:26 Dave Kreskowiak 16-May-12 7:26  RugbyLeague wrote: using ClickOnce Mistake #1. Don't. Use WiX, or Advanced Installer, or InstallShield, or some other dedicated packaging tool and make a proper installation. You'll have to far more control over your setup instead of fighting with the limitations of ClickOnce.

Re: Click Once and file associations Dave Kreskowiak18-May-12 2:06 Dave Kreskowiak 18-May-12 2:06  That's not the problem. No. The only way to do that would be to make every user an Administrator. I don't know anyone today that's going to do that.

Hence clickonce Re: Click Once and file associations Dave Kreskowiak18-May-12 3:27 Dave Kreskowiak 18-May-12 3:27  Like I said. That's not the problem. The problem is you need Administrators or a software deployment system to install the software. If you don't have Admins that like walking around to every machine installing software, you need a software delivery system to install it for you, like System Center Configuration Manager, or LANDesk, or something similar. BTW, when a user clicks on a ClickOnce link, the installation is run as the user, not an administrator.

We have SCCM but the people in charge of that tend to only use it for apps rolled out to 100s - my apps usually only target 30 to 40 users - ClickOnce is great for that.

The problem is that you're running into the limitations of ClickOnce. The only REAL solution to the problem is to repackage using a normal packaging tool. Then you distribute that package using SCCM.

So far I have been quite happy with ClickOnce - as you say it has limitations but nothing to make it unuseable Re: Click Once and file associations Dave Kreskowiak28-May-12 6:47 Dave Kreskowiak 28-May-12 6:47  Being a SCCM person where I work (and over 800 applications), I find that ridiculous. We ship everything, even down to manually installed applications on single workstations.

You've used WinForms instead. Judging from the error syntax your project is a WebForms ASP.Net prject. You should use the right DLL.
