• Game Technologies: DirectX, XNA, XACT, etc. Blitting?

  I've checked through the XNA Documentation, but there doesn't seem to be any way to 'blit'. For those of you unfirmiliar with 'blit': Blit is a way to draw something. For example, say you create a "Texture2D" variable, set the size etc... But the texture is blank. The normal way to create a texture to this is to load up a bitmap image with it through the ContentManager, right But what if you want to use a whole sprite-sheet with many images Back to the blank, say, 65 x 65 bitmap image, you obviusly don't want this 2D image of the player to be a whole 1024x768 sprite-sheet. So this is where I used blitting in other programs, it basically asks for the x, y co-ordinates, and the length of the bitmap and takes a picture from that x,y and 'c ...Show All

• Visual C++ Problems verifying login against AD with more than one domain

  Hi, Searched the forum and net for help with my little problem but haven't found anything, please redirect me if you know the place. :) Anyways I have this small C++ program that verifies user login and password against a domain in AD. Works fine when there's just one domain to take care off. But now a customer wants to use it in an environment were they have more than one domain. I'm quite sure I tested against more than one domain when I wrote the app, but I could've done it wrong. AD is not my strongest side. It could be that they have one domain with subdomains, and I want to verify against the subdomains. This is the code i Use to verify: hr = ADsOpenObject(CA2W(cDomain), // Path to AD.

• Visual Basic save as new project

  I want to open an existing project in vb 2005, modify it and save as a new project keeping the existing one unchanged. Is there a way of doing this.

• Visual Studio Anonymous access and SSL

  I've got my VSS database configured for web access using SSL and the VSS Web Service. Should I be allowing anonymous access to the VSS Web Service virtual directories I think this is the default set-up, but want to be sure. I had loads of problems getting this to work at all, so I have manually configured just about everything. I do require an SSL connection to the service, so VSS usernames and passwords should be encrypted and I should be good to go correct Thanks. Sorry, let me clarify...  I get that no matter what I need VSS user accounts.  What I am confused on is if those accounts need to be synched with the users NT login   I understand this to be the case with VSS Internet over H ...Show All

• .NET Development Bug? : Sgen breaks web-service serialization

  I am using the noaa weather web service and it works fine if I have not run sgen on the assembly. I have sgen disabled in the project settings and instead run it explicitly in the main build. I run sgen using the command: sgen /a:myassembly.dll /force /compiler:/keyfile:myassembly.snk This creates an [assembly_name].XmlSerializers.dll and when running the application again, the same call to the web-service fails with the following exception. This is internal to the web-service code so I'm stuck for what to do other than not run sgen: System.InvalidOperationException: There was an error generating the XML document. ---> System.ArgumentException: Item has already been added.

• Visual Studio What is #IND, #DEN etc.

  Hi, Often, if some floating point operations fail, i see values such as -1.#IND000000000000000000000 and 3.4353453453535342#DEN in the Debugger. Does anyone know what exactly this means. I could not find any documentation explaining these special double values (#DEN, #IND etc.). Thanks for help, cheers, Stefan I can't seem to find #DEN but not #IND is floating point NAN (not a number).

• Visual Studio Team System Customising WorkItem & Work Flow

  Hi All, I am trying to customise Work Item Template. This Customisation also include definning workflow. i am not clear about this work flow what is the relation between WorkItem customisation & workflow. Any inputs with good practicle example will be highly appreciated. Thanks. Work Flow is used to define the behaviors of your fields when the item in different state or transition. You clould want some filed is readonly or required when the item in Active state. Or you don't want a bug can be modified from Active to Closed directly. All these things can be implemented in WorkFlow. BTW: The customization tool PTE (Version 0.9.2346.34929) has a severy bug when you define WorkFlow. Memory Leak!! ...Show All

• Software Development for Windows Vista USB Video (UVC) extension unit

  I am having difficulty accessing UVC extension units using DirectShow IKsControl::KsProperty. When I try doing KSPROPERTY_TYPE_GET | KSPROPERTY_TYPE_TOPOLOGY on PropertyId 0, I get back the extension unit GUID and six additional bytes (1,1,3,2,1,0,6) which do not seem to be defined in the DDK. PropertyId 1 returns error 0x80070490. Any suggestions The data for KSPROPERTY_EXTENSION_UNIT_INFO (PropertyId = 0) is copied over from the device's extension unit descriptor which is cached during device startup. During startup, the driver issues a number of control requests to the device like GET_INFO, GET_LEN, GET_MIN and GET_MAX. The value returned by GET_INFO tells the driver which of GET and SET requests are v ...Show All

• SQL Server Migrating SQL 2000 to a new sever

  I am upgrading our SQL 2000 Server hardware. I am looking for a way to "mirror" this server. The only items that we are changing are updating the hardware and the OS will be Server 2K3 instead of Server 2k Does anyone have a reliable method, or suggested processes for migrating one server to another Best way of doing this is to backup your system databases and restore them on the win2003 server. Check out a paper called "Move your Master" from www.SQLServerCentral.com When you successfully have moved your master you can backup and restore all the databases on the new server. If you have a large amount of databases detach from hostserver - attach on targetserver. Users should ...Show All
