• Visual Studio Express Editions Help with class templates

• Windows Live Developer Forums Restrict VE Map scroll

  My client has just asked me this – and I am not sure if it can be done My client wants to limit the outer edge of the map scroll to an area around the UK. (to stop users VE’ing their holiday destinations during work hours) Any suggestions IF this can be done Yes but that is good if you are in on a particular zoom, however lets say you are at county level and start panning across the uk, when you reach the boundary I would actually like to un-pan the the last move. Is this possible like reversing the last view change rather than setting map to required centre. I am guessing that the only way would be to record the center of the map prior to the pan and if it goes out of boundary then move ba ...Show All

• .NET Development .NET framework adoption rate?

  We are trying to decide on whether to maintain 1.1 compatibility for our software or use some of the new features in 2.0. Thus we need to know how widely .NET 1.1 has been adopted by end users. If few machines have 1.1 installed we might as well use 2.0 since most users will have to download the redistributable anyway. But if many 2000/XP machines already have .NET 1.1 installed it would make sense to rather stay compatible with 1.1, since our application footprint is small relative to the redistributable. I haven't been able to find good information on the adoption rate of .NET, so I would appreciate any links. It would also be interesting to know why the .NET framework has always been (still is) an optional component in the service packs ...Show All

• Windows Forms Comparing .NET diagramming components

  Im considering using the Nevron .NET Vision toolkit for UI and Diagraming componentry to build an windows application under .NET 2.0/VS2005/C# to create/edit network diagrams, dependency trees etc. From what I have seen the toolkit seems reasonable. However, as I am very new to winForms programming I would be interested if anyone could maybe point to some other candidates I could consider. Any tips appreciated. ...Show All

• Silverlight (formerly WPF/E) Info on support for other platforms?

  Hi, I know that as of right now MS is only planning on supporting the browsers that are currently supported in the CTP, and I've read on a developer's blog that MS will be relying on partners to implement support for other platforms. Is there any of this work with partners underway Is there anything else that I'm missing I'm giving a presentation on WPF(/E) to some execs at my company, and I'd like to be able to mention something about support on other platforms because I know this will be a con when compared to Flash. Thanks, HV "WPF/E" was built for the internet and as such should work anywhere people browse from. That said, we have limited resources and we need to optimize our effort around th ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Render triangles of subset

  Hi, I wondering if its possible to render the triangles of a subset one by one Thanks, -Dave Sure but you have to do it by your own. First you need to get the attribute data for the subset and then you can loop. (I have not include method names because I don’t know which language and mesh class you use) I hope you would do this only for diagnostic purpose because it will kill the performances. ...Show All

• .NET Development Formatting numbers

  .net I am building a solution that shows two numbers. VAT on sales and VAT on costs. I can obtain the two values through a SQL query Sum(amount) * 0.175 etc etc however when I want to subtract one from the other I get a single digit number. For example my sql query might return 14,5435.00 and 5,746.00 but the value i get after i try to subtract them is 9. I have tried using format but that just returns a letter "N" in this case. Label35.Text = Format(objDataRow.Item( "totalclientyear" ), "N" ) objDataRow.Item("") return an object. You need to convert the data to a number for the format to work Label35.Text= CDec(ObjDataRow.Item("totalclientyear" ...Show All

• Visual Studio Team System assigning work items to many people

  I'm using team system and microsoft project to create and modify work items. I can create task work items in either project or team explorer and pass them backwards and forwards without problem if I only assign to a single person. If I try to assign to multiple resources (a comma separated list of names) in project then the work item will not publish to team system. If I remove all the names but one then it works again. I can see that it is reasonable for some work items (i.e., bugs) to only be assignable to a single person but it seems unbelieveable that all tasks on all development projects would only be assigned to one person. Someone tell me that it ain't so! Do I need to create a custom work item I'm on windows xp pro sp2 and ...Show All

• SQL Server MSDE (SQL Server does not exist or access denied.)

  Hi all, I'm getting this error message when I try to connect my MSDE database from other machine using enterprise manager application. Both of the machines are WinXP SP2. I found some solution such as using 'SQLServer Network Utility' but didn't work out for me. I even can not connect my database on my computer using TCP/IP. When I connect with name, it worked fine. I already enable both TCP/IP and Named pipe protocol on the MSDE machine. If someone has solution on that please let me know. Thanks, Myo If you have SQL Server 2005 installed on the same box as the MSDE, you need make sure SQL Browser is running. Make sure the ports (UDP/1434 and your TCP Port) are open if firewall exists.

• SQL Server import from Access to SQL, not knowing the table format

  I need to import few tables from MS Access to MS SQL but the table structure in Access is always different, as I would like the destination table in SQL to be. Therefore I would like that a table would be created in SQL at runtime, according to the structure the Access table accessed has. i'm not sure about this, but i think you can use the script task to determine the access table schema.  then, you could use this schema information to dynamically create the sql server table. ...Show All
