• .NET Development Using System.Net.Mail with Gmail is Faulty

  Can someone try this on their computer with their Gmail account I'm not sure if its every mail service or just gmail, because gmail is the only mail service that allows for smtp access (hotmail and yahoo don't) that I use. The problem is that the mail message send completed event is not triggered, even when its done. The email is sent and all, its just the event isnt triggered. Mybe is the same problem that here: To send to hotmail, your server ip must have reverse dns resolution. This meaning, that for example from your dynamic IP internet connection you can't send to hotmail. You must have a domain name associtate at your IP address. This is a way to avoid spammers.

• Visual C# Custom Business Objects as Data Sources

  I've built a class library and it builds fine. I go into the Data Sources of my client windows application but it doesnt appear in the data sources object list even though I've referenced it. I've done a couple of tests with building dummy class libraries and I get this problem intermitantly. I'm new to C# and so I think it could be something I'm doing wrong. Can anyone point me in the right direction. Thanks a lot PJ. I'm using .Net 2.0. There was actually a problem with my business object class which was why it wasn't showing up in the list but now its fine. ...Show All

• Visual Studio 2008 (Pre-release) Any way to create BreadCrumb navigation in Navbar?

  In a WPF Browserlike app I'd like to show a breadcrumb navigation bar instead of the 'back' and 'next' buttons, showing a trail of the pages the user has visited, offering to go back to any page by clicking the breadcrumb. Can this be done in the controltemplate of the NavigationWindow This would contain the same pages as the navigation dropdown list does. Just in case it's not clear what I'm talking about I added a small project , showing a static navigation where I would have liked the automatic one.

• Visual Studio Team System VS2003 against TFS

  Hi, I have migrated VS2003 project from VSS to TFS. I have installed MSSCCI Provider for connection with TFS from IDE VS2003. In IDE VS2003, I have connected to TFS. When I checked out some file under Source Control, then I changed it and Checked in, this file, project and solution kept in check out state. And I might to do undo check out. Sometime, this action made the problem, by rolling back the actions, which I did. I have also noticed that, TFS made double folder structure to local folders (It was copying parent folder to new folder which had the same name as parent folder), because TFS added new mappings to current workspace. It's expected behavior And what can I do instead of undo check out Thanks Janko The & ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Blue Screen of Death or System Restart

  I have XNA installed on my home computer, and on my laptop, and it happens rather often (a few times a day) that when I try run the project, or click the Save All button, I get a system reboot or a BSOD. It happened once too when I tried to move a file to another folder, in the Solution Explorer. Since it happens on two different computers, I was wondering if someone else has had the same problem. Any known bug/solution Thank you!
