• Smart Device Development How to use RegisterRunningDevice

  Hi all !!!!!!!!!!!! I'm on an important project of network device developping. I made a UPNP AV Control Point that works very well. Now I'm building a MediaServer device and I'm facing a problem about register the device. I did my own implementation. Since it doesn't work, I tried the example provided by the microsotf SDK and I get the same error after calling IUPnPRegistrar::RegisterRunningDevice. the return result of the function is 8004a025. I searched the meaning of this value and I didn't obtain anything. If somebody can know the meaning of this or the causes of non-running of this function, I'm waiting your contibutions because without running the function I canont progress. Thank you very much. ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. XNA with C# Professional version

  I can find any of this in the FAQ so I'll ask: Is there a way to get/install and use the XNA framework with the professional version of C# My Visual Studio Professional already as C# installed. I'd like to be able to play with XNA without playing to many installation games Thanks, Gary Not yet. I tried already a week ago (when trying to get XNA working on my x64 platform) to get it to work in VS 2005 Pro, but it is not that easy. Yes, it is quite annoying, especially since my beloved Code Rush doesn't work in Express But maybe it is possible to copy some files over and get it to work, will try again in a few days when I get annoyed Code Rush is still missing. In the future Ms will make bigger versio ...Show All

• Visual C# How to get a page source code of URL programmatically?

  From a C# routine I need to go to a URL page and download the HTML source code of that page bypassing the browser. I then intent to analyze the code and extract another URL -- but I already know how to handle it. I prever to have this page in memory, as a string variable, not as a disk file--it is intended for a very temporary usage. The challenge for me is to figure out how to have the program download the HTML code without alerting the Internet Explorer Browser. I am sure it is a simple problem for a longtimer. Hope for help. Thanks You can fetch the html page using HttpWebRequest class: HttpWebRequest request = ( HttpWebRequest ) HttpWebRequest .Create(url); using ( Stream stream = request.GetResponse().GetRespo ...Show All

• SQL Server Changinge fonts for properties dialog in SSMS

  I would like to change the font used in SQL Server Management Studio's database properties dialog to something that is not sans-serif so that I can easily tell when a db file is on drive I (I) vs drive l (L) . I've changed every single entry under Tools > Options > Environment >Fonts and Colors to use Courier New as well as every single entry under the system's Display Properties > Appearance > Advanced, and the font in the SSMS server tree and in the object properties dialogs are still sans-serif fonts. Does anyone know of a way to change this Thanks! ...Show All

• SQL Server During processing - error in Event Viewer only?

  A cube I'm trying to process is consistently failing ("the process completed with failure."). Since no specific error was given, I checked the event viewer and noted this for MSSQLServerOLAPServices: "OLE DB error: OLE DB or ODBC error: Invalid object name "SiteAccountProfile"; 42S02. SiteAccountProfile is a table I query from in my DSView (and it's also a dimension table), but I can't imagine what the error is referring to / complaining about. Anyone know what this might mean Okay, more tinkering yielded this nugget: "SiteAccountProfile" is used as a reference dimension (IE another dimension uses it as the reference dimension) on several measures. On a particular measure (this happened to be th ...Show All

• Visual Studio Setting my own Environment variables

  Hi, I created an environment variable like this: set TARGETPATH=D:\SOMEPATH in DOS shell i referenced it in the proj file as $(TARGETPATH). In the XML it is happy. If i open the IDE it doesn't recognise. If is use a system environment variable the IDE is happy. Where do i need to setup custom environment variables so that they can be seen by the IDE the way system ones are.

• Visual Studio Express Editions install a program from C# express with only .Net 1.1

  Is this possible I wrote a program for my associates at work, unfortunately I made the huge mistake of not checking whether or not they had .NET 2.0 installed, unfortunately, they do not, instead they have .NET 1.1. I cant ask them to install 2.0 so im in a pickle, is there any way to set up my program to only use .NET 1.1, i dont mind modifying my code or anything, if there is, please please let me know. Thank you! Express generates assemblies that only work with the .NET 2.0 framework. You could recompile your app using the .NET 1.1 command line compilers but that's quite awkward. Ask you friends to download and install the .NET 2.0 framework , it is a one-time installation they'll eventually need to ma ...Show All

• SQL Server Auto Number Sequence

  How can I create a number sequence starting at a certain number and continue on for the number of records I have. For example I have 3000 records in my table and a field named I created called RecordId which I'd like to start at number 1 and goto 3000 (or maybe even start at 9000 and goto 12000 or however many records there are). In my pseudo SQL code Im guessing it would be something like... select * from Incident update Incident set RecordId( i=9000; i<=Number of Records in Table; i++) Whats the easiest way to do this A potentially more expressive function you could use in place of identity is the row_number. select row_number over( partiton by ... order by ...) + startin_numbe ...Show All
