• How to get quality sprite sheet generation with rotations

  - by BenMaddox

  I'm working on a game that uses sprite sheets with rotation for animations. While the effect is pretty good, the quality of the rotations is somewhat lacking. I exported a flash animation to png sequence and then used a C# app to do matrix based rotations (System.Drawing.Drawing2D.Matrix). Unfortunately, there are several places where the image gets clipped. What would you suggest for a way to get high quality rotations from either flash or the exported PNGs? A circle should fit within the same image boundaries. I don't mind a new program that I must write or an existing program I must download/buy.

• Fresh Install of SQL Server 2008 doesn't install managment studio. Help!

  - by Jordan S

  Ok I am running Windows 7, 64 bit. I cleaned of SQL server 2005 completely off my system leaving only SQL Compact Edition. I went here http://www.microsoft.com/downloads/details.aspx?FamilyID=01af61e6-2f63-4291-bcad-fd500f6027ff&displaylang=en and installed SQL Server 2008 Express Edition Service Pack 1. After the install, under my start bar menu all i have for SQL configuration tools are the Configuration Manager, Error and Usage Reporting and the Install Center. I don't have the SQL Managment Studio. So I went here http://www.microsoft.com/downloads/details.aspx?FamilyID=08e52ac2-1d62-45f6-9a4a-4b76a8564a2b&displaylang=en and downloaded the SQL Server 2008 Management Studio Express but when I try to install it I get a warning says This program has known compatibility issues and that I need to Install SQL Server 2008 Service Pack 1. I thought that is what I installed. So, I tried to continue running the install but I then get an error message that says Invoke or BeginInvoke can not be called on a Form before it is opened... How can I check if Service pack 1 is installed or not? What should I do?

• Random number generation algorithm for human brains?

  - by Magnus Wolffelt

  Are you aware of, or have you devised, any practical, simple-to-learn "in-head" algorithms that let humans generate (somewhat "true") random numbers? By "in-head" I mean.. preferrably without any external tools or devices. Also, a high output (many random numbers per minute) is desirable. Asked this on SO but it didn't get much interest. Maybe this is better suited for programmers.. :) I'm genuinely curious about anything that people might have come up with on this problem.

• SQL 2008 Backups to UNC Share Failing 0xC002F210

  - by Matty Brown

  This problem is driving me NUTS!! We take backups of all of our production databases to a network share, which are then backed up to tape nightly. 8pm Mon-Fri - Full backup, followed by log backup 7am-7pm Mon-Fri, at half-hour interval - Log backup Our backups have been working in this manner since we migrated from SQL Server Standard 2000 to 2008, 3 years ago. Recently, the first log backup on Mondays have been failing. Not every time, but almost every time! The rest of the week, we've had no problems. I guess the issue may have something to do with the size of the log backup that's attempted after a weekend of no backups. Now onto the issue I need a fix for... All this week, every full backup on our biggest two databases have failed (Both backups < 1GB compressed). There's plenty of disk space on the source and destination servers. I'm guessing the issue is to do with the amount of time it takes to complete the backups of these databases, and/or the size of the backup files required to complete these backups. Changing the backup destination to local storage works fine (and very, very fast in comparison). From the Job History, I can find a few hints as to what the problem could be... Code: 0xC002F210 (Always this code, but a mix of the following descriptions...) "The operating system returned the error '64(failed to retrieve text for this error. Reason: 1815)' while attempting 'SetEndOfFile' on '\drserver\SQLBackups\Database.bak'. BACKUP DATABASE is terminating abnormally. "The operating system returned the error '64(failed to retrieve text for this error. Reason: 1815)' while attempting 'FlushFileBuffers' on '\drserver\SQLBackups\Database.bak'. BACKUP DATABASE is terminating abnormally. Please help save my hair and sanity!!

• Chicago Architects Group &ndash; Document Generation Architectures

  - by Tim Murphy

  Thank you to everyone who came out to the Chicago Architects Group presentation last night.  It seemed like the weather has a way of keeping a large portion of the people who registered from making the meeting.  There was some lively networking going on before and after the meeting.  I enjoyed the questions that people had during the presentation.  It helped to bring out some of the challenges with dealing with the OOXML and ODF standards from an architecture perspective. I have posted the Slides and Code.  Feel free to contact me with any questions. For those of you who missed the presentation I will be giving a similar one at the Lake County .NET Users Group on June 24th. The next CAG presentation will be July 20th.  The presentation will be Architecting A BI Installation by David Leininger.  Look for the registration to open in the next day or so. del.icio.us Tags: Chicago architects Group,OOXML,ODF,BI,LCNUG,slides,code

• Long delays in Unity3D substance generation

  - by Josh Buhler

  Currently working on an iOS/Android project in Unity3d, and we're seeing some incredibly long times for generating substances between testing runs. We can run the game, but once we shut down the playback, Unity begins to re-import all off the substances built using Substance Designer. As we've got a lot of these in our game, it's starting to lead to 5 minute delays between testing runs just to test a small change. Any suggestions or parameters we should check that could possibly prevent Unity from needing to regenerate these substances every time? Shouldn't it be caching these things somewhere?

• Game Resource Generation

  - by Darthg8r

  I am currently building a game that has a "City" entity. These cities generate and consume resources such as food variably over a period of time. I need to be able query the server often to find exactly how much food the city at any given point. These queries can take place multiple times per minute. There could also be 400,000 cities to track at a given time. How would you handle tracking these resources? Would you do it in real time, keeping an instance of the city in memory on the server, with some sort of a snapshot in time of the resources, then computing the growth/consumption from that snapshot time for subsequent queries? Would you work exclusively with a database, using a similar "snapshoting" scheme? Maybe a mixture of the 2, caching recently queried cities in memory for a period of time? There is also a lot of other data that each city needs to track. A player can queue units to build in a barrack. The armies available in the city will need to be updated as units complete. I'm interested in everyone's input on where/when/how you'd manage the real time data.

• UV Atlas Generation and Seam Removal

  - by P. Avery

  I'm generating light maps for scene mesh objects using DirectX's UV Atlas Tool( D3DXUVAtlasCreate() ). I've succeeded in generating an atlas, however, when I try to render the mesh object using the atlas the seams are visible on the mesh. Below are images of a lightmap generated for a cube. Here is the code I use to generate a uv atlas for a cube: struct sVertexPosNormTex { D3DXVECTOR3 vPos, vNorm; D3DXVECTOR2 vUV; sVertexPosNormTex(){} sVertexPosNormTex( D3DXVECTOR3 v, D3DXVECTOR3 n, D3DXVECTOR2 uv ) { vPos = v; vNorm = n; vUV = uv; } ~sVertexPosNormTex() { } }; // create a light map texture to fill programatically hr = D3DXCreateTexture( pd3dDevice, 128, 128, 1, 0, D3DFMT_A8R8G8B8, D3DPOOL_MANAGED, &pLightmap );

float fU = ( f11 * f02 - f01 * f12 ) * invDenom; float fV = ( f00 * f12 - f01 * f02 ) * invDenom; // Check if point is in triangle if( ( fU >= 0 ) && ( fV >= 0 ) && ( fU + fV < 1 ) ) return true; return false; } Screenshot Lightmap I believe the problem comes from the difference between the lightmap uv coordinates and the pixel center coordinates...for example, here are the lightmap uv coordinates( generated by D3DXUVAtlasCreate() ) for a specific face( tri ) within the mesh, keep in mind that I'm using the mesh uv coordinates to write the pixels for the texture: v[ 0 ].uv = D3DXVECTOR2( 0.003581, 0.295631 ); v[ 1 ].uv = D3DXVECTOR2( 0.003581, 0.003581 ); v[ 2 ].uv = D3DXVECTOR2( 0.295631, 0.003581 ); the lightmap texture size is 128 x 128 pixels. The upper-left pixel center coordinates are: float halfPixel = 0.5 / 128 = 0.00390625; D3DXVECTOR2 pixelCenter = D3DXVECTOR2( halfPixel, halfPixel ); will the mapping and sampling of the lightmap texture will require that an offset be taken into account or that the uv coordinates are snapped to the pixel centers..? ...Any ideas on the best way to approach this situation would be appreciated...What are the common practices?

• PHP ORM style of querying

  - by Petah

  Ok so I have made an ORM library for PHP. It uses syntax like so: *(assume that $business_locations is an array)* Business::type(Business:TYPE_AUTOMOTIVE)-> size(Business::SIZE_SMALL)-> left_join(BusinessOwner::table(), BusinessOwner::business_id(), SQL::OP_EQUALS, Business::id())-> left_join(Owner::table(), SQL::OP_EQUALS, Owner::id(), BusinessOwner::owner_id())-> where(Business::location_id(), SQL::in($business_locations))-> group_by(Business::id())-> select(SQL::count(BusinessOwner::id()); Which can also be represented as: $query = new Business(); $query->set_type(Business:TYPE_AUTOMOTIVE); $query->set_size(Business::SIZE_SMALL); $query->left_join(BusinessOwner::table(), BusinessOwner::business_id(), SQL::OP_EQUALS, $query->id()); $query->left_join(Owner::table(), SQL::OP_EQUALS, Owner::id(), BusinessOwner::owner_id()); $query->where(Business::location_id(), SQL::in($business_locations)); $query->group_by(Business::id()); $query->select(SQL::count(BusinessOwner::id()); This would produce a query like: SELECT COUNT(`business_owners`.`id`) FROM `businesses` LEFT JOIN `business_owners` ON `business_owners`.`business_id` = `businesses`.`id` LEFT JOIN `owners` ON `owners`.`id` = `business_owners`.`owner_id` WHERE `businesses`.`type` = 'automotive' AND `businesses`.`size` = 'small' AND `businesses`.`location_id` IN ( 1, 2, 3, 4 ) GROUP BY `businesses`.`id` Please keep in mind that the syntax might not be prefectly correct (I only wrote this off the top of my head) Any way, what do you think of this style of querying? Is the first method or second better/clearer/cleaner/etc? What would you do to improve it?

• Data from a table in 1 DB needed for filter in different DB...

  - by Refracted Paladin

  I have a Win Form, Data Entry, application that uses 4 seperate Data Bases. This is an occasionally connected app that uses Merge Replication (SQL 2005) to stay in Sync. This is working just fine. The next hurdle I am trying to tackle is adding Filters to my Publications. Right now we are replicating 70mbs, compressed, to each of our 150 subscribers when, truthfully, they only need a tiny fraction of that. Using Filters I am able to accomplish this(see code below) but I had to make a mapping table in order to do so. This mapping table consists of 3 columns. A PrimaryID(Guid), WorkerName(varchar), and ClientID(int). The problem is I need this table present in all FOUR Databases in order to use it for the filter since, to my knowledge, views or cross-db query's are not allowed in a Filter Statement. What are my options? Seems like I would set it up to be maintained in 1 Database and then use Triggers to keep it updated in the other 3 Databases. In order to be a part of the Filter I have to include that table in the Replication Set so how do I flag it appropriately. Is there a better way, altogether? SELECT <published_columns> FROM [dbo].[tblPlan] WHERE [ClientID] IN (select ClientID from [dbo].[tblWorkerOwnership] where WorkerID = SUSER_SNAME()) Which allows you to chain together Filters, this next one is below the first one so it only pulls from the first's Filtered Set. SELECT <published_columns> FROM [dbo].[tblPlan] INNER JOIN [dbo].[tblHealthAssessmentReview] ON [tblPlan].[PlanID] = [tblHealthAssessmentReview].[PlanID]

• Use CompiledQuery.Compile to improve LINQ to SQL performance

  - by Michael Freidgeim

  After reading DLinq (Linq to SQL) Performance and in particular Part 4  I had a few questions. If CompiledQuery.Compile gives so much benefits, why not to do it for all Linq To Sql queries? Is any essential disadvantages of compiling all select queries? What are conditions, when compiling makes whose performance, for how much percentage? World be good to have default on application config level or on DBML level to specify are all select queries to be compiled? And the same questions about Entity Framework CompiledQuery Class. However in comments I’ve found answer  of the author ricom 6 Jul 2007 3:08 AM Compiling the query makes it durable. There is no need for this, nor is there any desire, unless you intend to run that same query many times. SQL provides regular select statements, prepared select statements, and stored procedures for a reason.  Linq now has analogs. Also from 10 Tips to Improve your LINQ to SQL Application Performance   If you are using CompiledQuery make sure that you are using it more than once as it is more costly than normal querying for the first time. The resulting function coming as a CompiledQuery is an object, having the SQL statement and the delegate to apply it.  And your delegate has the ability to replace the variables (or parameters) in the resulting query. However I feel that many developers are not informed enough about benefits of Compile. I think that tools like FxCop and Resharper should check the queries  and suggest if compiling is recommended.

• SQL SERVER 2005 with Windows 7 Problems

  - by azamsharp

  First of all I restored the database from other server and now all the stored procedures are named as [azamsharp].[usp_getlatestposts]. I think [azamsharp] is prefixed since it was the user on the original server. Now, on my local machine this does not run. I don't want the [azamsharp] prefix with all the stored procedures. Also, when I right click on the Sproc I cannot even see the properties option. I am running the SQL SERVER 2005 on Windows 7. UPDATE: The weird thing is that if I access the production database from my machine I can see the properties option. So, there is really something wrong with Windows 7 security. UPDATE 2: When I ran the orphan users stored procedure it showed two users "azamsharp" and "dbo1". I fixed the "azamsharp" user but "dbo1" is not getting fixed. When I run the following script: exec sp_change_users_login 'update_one', 'dbo1', 'dbo1' I get the following error: Msg 15291, Level 16, State 1, Procedure sp_change_users_login, Line 131 Terminating this procedure. The Login name 'dbo1' is absent or invalid.

• Physics-based dynamic audio generation in games

  - by alexc

  I wonder if it is possible to generate audio dynamically without any (!) audio assets, using pure mathematics/physics and some input values like material properties and spatial distribution of content in scene space. What I have in mind is something like a scene, with concrete floor, wooden table and glass on it. Now let's assume force pushes the glass towards the edge of table and then the glass falls onto the floor and shatters. The near-realistic glass destruction itself would be possible using voxels and good physics engine, but what about the sound the glass makes while shattering? I believe there is a way to generate that sound, because physics of sound is fairly known these days, but how computationaly costy that would be? Consumer hardware or supercomputers? Do any of you know some good resources/videos of such an experiment?

• Cloning a NAS drive which hosts a SQL Server DB

  - by Adrian Hand

  We have a system in the field running a server application which is suffering with major performance issues. The system in question has 2 onboard 300gb sas drives in RAID 5 from which it boots Windows Server 2003, and a 6tb buffalo terastation NAS unit (also RAID 5) to which the server app does all of its reading and writing. I believe the terastation is the source of all our woes. Whilst under load, reads and writes tick by at something of the order of 1meg/sec, though the network in question is hardly utilised. The terastation contains various data, but crucially hosts a full instance worth of SQL Server .mdf and .ldf files (master etc - the whole shooting match) I wish to stop all the services on the server, then take everything on the terastation and essentially clone it to some alternative onboard storage, so as to eliminate the terastation from the equation as far as poor performance is concerned. ie the terastation is currently drive D: - I want to copy everything off and then have the duplicate assume the drive letter so that as far as the software is aware, nothing is different. This is tricky because of the mdf and ldf files - everything else will work with a straight up file copy. Can anyone suggest a means to achieve what I am describing? Many thanks!

• My Generation Drivers DropdownList Empty

  - by hmloo

  I just installed MyGeneration 1.3.1 on my Windows Vista, and when I try to setup the default settings there are no drivers to select from. but it's OK in my Windows XP machine. At last I got the answers from search engine, it is caused by multi .Net Frameworks coexist and MyMeta.dll is registered by the .Net v2.0 while it should be registered with the .Net v4.0. So we have to manually register the dll. Please follow these steps: 1. Run Visual Studio Command Prompt (2010) with "Run as Administrator". 2. Enter the command "regasm.exe "C:\Program Files\MyGeneration13\MyMeta.dll" /tlb: MyMeta.tlb" 3. Exit Command Prompt when successfully registered. 4. Run MyGeneration and the proplem should be disapear. Hope this helps. Thanks for reading.

• Automated backups for Windows Azure SQL Database

  - by Greg Low

  One of the questions that I've often been asked is about how you can backup databases in Windows Azure SQL Database. What we have had access to was the ability to export a database to a BACPAC. A BACPAC is basically just a zip file that contains a bunch of metadata along with a set of bcp files for each of the tables in the database. Each table in the database is exported one after the other, so this does not produce a transactionally-consistent backup at a specific point in time. To get a transactionally-consistent copy, you need a database that isn't in use.The easiest way to get a database that isn't in use is to use CREATE DATABASE AS COPY OF. This creates a new database as a transactionally-consistent copy of the database that you are copying. You can then use the export options to get a consistent BACPAC created.Previously, I've had to automate this process by myself. Given there was also no SQL Agent in Azure, I used a job in my on-premises SQL Server to do this, using a linked server configuration.Now there's a much simpler way. Windows Azure SQL Database now supports an automated export function. On the Configuration tab for the database, you need to enable the Automated Export function. You can configure how often the operation is performed for you, and which storage account will be used for the backups.It's important to consider the cost impacts of this as well. You are charged for how ever many databases are on your server on a given day. So if you enable a daily backup, you will double your database costs. Do not schedule the backups just before midnight UTC, as that could cause you to have three databases each day instead of one.This is a much needed addition to the capabilities. Scott Guthrie also posted about some other notable changes today, including a preview of a new premium offering for SQL Database. In addition to the Web and Business editions, there will now be a Premium edition that has reserved (rather than shared) resources. You can read about it all in Scott's post here: http://weblogs.asp.net/scottgu/archive/2013/07/23/windows-azure-july-updates-sql-database-traffic-manager-autoscale-virtual-machines.aspx

• SQL Server DBA - How to get a good one!

  - by ETFairfax

  I'm a lone developer. I am currently developing an application which is seeing me get way way way out of my depth when it comes to SQL DBA'ing, and have come to realise that I should hire a DBA to help me (which has full support from the company). Problem is - who? This SO thread sees someone hire a DBA only to realise that they will probably cause more harm then good! Also, I have just had a bad experience with a ASP.NET/C# contractor that has let us down. So, can anyone out there on SO either... a) Offer their services. b) Forward me onto someone that could help. c) Give some tips on vetting a DBA. I know this isn't a recruitment site, so maybe some good answers for c) would be a benefit for other readers!! BTW: The database is SQL Server 2008. I'm running into performance issues (mainly timeouts) which I think would be sorted out by some proper indexing. I would also need the DBA to provide some sort of maintenance plan, and to review how our database will deal what we intend at throwing at it in the future!
