• Change of domain deleted data in Team Foundation Server?

  - by glumesc

  Dear All, Maybe my google-fu is failing me, but I cannot seem to find any information on the following: My Windows user account was recently moved, accidentally, to another domain in my company's Active Directory. While in the other domain, I was unable to access my data stored in TFS 2008 (e.g. shelvesets, pending changes, workspaces, etc). I assume this was because it was associated with my ORIGINALDOMAIN\userId account, rather than NEWDOMAIN\userID account. My account has now been moved back to ORIGINALDOMAIN, however I still cannot see any of my data in TFS. In fact, it appears that all of my data (all my shelvesets!) have been deleted. It is almost as if TFS saw that my userId had disappeared from ORIGINALDOMAIN and assumed that I had been "deleted" and thus deleted all my data. Has anybody else encountered this? Is there hope for my data or am I royally stuffed? Thanks in advance, Steve

• Microsoft Sync Framework - How to reprovision a table (or entire scope) after schema changes?

  - by Rabbi

  I have already setup syncing with Microsoft Sync Framework, and now I need to add fields to a table. How do I re-provision the databases? The setup is exceedingly simple: Two SQL Express 2008 servers The scope includes the entire database Using Microsoft Sync Framework 2.0 Synchronizing by direct access. Using the standard new SqlSyncProvider Do I make the structural changes at both ends? Or do I only change one server and let Sync Framework somehow propagate the change? Do I need to delete the _tracking tables and/or the stored procedures? How about the triggers? Has anyone been using the Sync Framework? Please help.

• Is it possible to raise an error if a variable assignment in a select returns multiple values?

  - by Brann

  I just found a bug on one of my softwares where I had forgotten a where clause. The code was something like that : declare @foo bigint declare @bar bigint select @foo = foo, @bar=bar from tbFooBar where (....a long list of condition goes there) (... and an extra condition should have went there but I forgot it) Unfortunately, the where clause I forgot was useful in very specific corner cases and the code went through testing successfully. Eventually, the query returned two values instead of one, and the resulting bug was a nightmare to track down (as it was very difficult to reproduce, and it wasn't obvious at all that this specific stored procedure was causing the issue we spotted) Debugging would have been a lot easier if the @foo=foo had raised an exception instead of silently assigning the first value out of multiple rows. Why is that this way? I can't think of a situation where one would actually want to do that without raising an error (bearing in mind the clauses 'distinct' and 'top' are there for a reason) And is there a way to make sql server 2008 raise an error if this situation occurs ?

• Clean way to combine multiple jars? Preferably using ant

  - by Jacob

  I have runtime dependencies on some external jars that I would like to "rejar" into a single jar. These external dependencies are stored in a external_jars directory, and I'd like to be able to not have to list each one out (e.g., to not need to change my build scripts if my dependencies change). Any thoughts? Google gave me a good answer on how to do this if you don't mind listing out each jar you want as a dependency: http://markmail.org/message/zijbwm46maxzzoo5 Roughly, I want something along the lines of the following, which would combine all jars in lib into out.jar (with some sane overwrite rules). jar -combine -out out.jar -in lib/*.jar

• What does MySqlDataAdapter.Fill return when the results are empty?

  - by Brian

  I have a 'worker' function that will be processing any and all sql queries in my program. I will need to execute queries that return result sets and ones that just execute stored procedures without any results. Is this possible with MySqlDataAdapter.Fill or do I need to use the MySqlCommand.ExecuteNonQuery() method? Here is my 'worker' function for reference: private DataSet RunQuery(string SQL) { MySqlConnection connection; MySqlCommand command; MySqlDataAdapter adapter; DataSet dataset = new DataSet(); lock(locker) { connection = new MySqlConnection(MyConString); command = new MySqlCommand(); command = connection.CreateCommand(); command.CommandText = SQL; adapter = new MySqlDataAdapter(); adapter.Fill(dataset); } return dataset; }

• Temporary intermediate table

  - by user289429

  In our project to generate massive reports in oracle we use some permanent table to hold intermediate results. For example to generate one report we run few queries and populate the table, at the final step we join the intermediate table with huge application tables. These intermediate tables are cleared for next report run. We have few concerns in performance areas. These intermediate tables are transactional and don't have statistics. Is it good idea to join these with application tables which are partitioned and have up to date statistics. We need these results stored in the intermediate tables to be available across requests from UI hence we are not in a position to use oracle provided temporary tables. Any thoughts on what could be done would be appreciated.

• Slickgrid, confirm before edit

  - by Evan

  I am making a slick grid and need the ability to add rows with a code column. For this to be possible the code column needs to be editable for the entire table. I am trying to work out a way that I can confirm the edit with a standard javascript confirm popup box. I tried putting one into the onedit event within the slickgrid constructor and that executed after the edit. I am led to believe that the edit function is independent from calling the edit stored procedure of the database. Is there a better way to go about this? RF_tagsTable = new IndustrialSlickGrid( LadlesContainerSG , { URL: Global.DALServiceURL + "CallProcedure" , DatabaseParameters: { Procedure: "dbo.TableRF_tags" , ConnectionStringName: Global.ConnectionStringNames.LadleTracker } , Title: "RF tags" , Attributes: { AllowDelete: true , defaultColumnWidth: 120 , editable: true , enableAddRow: true , enableCellNavigation: true , enableColumnReorder: false , rowHeight: 25 , autoHeight: true , autoEdit: false , forceFitColumns: true } , Events: { onRowEdited : rowEdited /*function(){ //this is my failed attempt var r=confirm("Edit an existing tag?") if (r){ alert(r); } else { alert(r); } }*/ , onRowAdded : rowAdded } });

• How to ignore the .classpath for Eclipse projects using Mercurial?

  - by Feanor

  I'm trying to share a repository between my Mac (laptop) and PC (desktop). There are some external dependencies for the project that are stored on different places on each machine, and noted in the .classpath file in the Eclipse project. When the project changes are shared, the dependencies break. I'm trying to figure out how to keep this from happening. I've tried using .hgignore with the following settings, among others, without success: syntax: glob *.classpath Based on this question, it appears that the .hgignore file will not allow Mercurial to ignore files that are also committed to the repository. Is there another way around this? Other ways to configure the project to make it work?

• How does Mach-O loader loads different NSString objects?

  - by overboming

  I have known that If you define a bunch of @"" NSString objects in the source code in Mac OS. These NSStrings will be stored in a segment in the Mach-O library. Section sectname __ustring segname __TEXT addr 0x000b3b54 size 0x000001b7 offset 731988 align 2^1 (2) reloff 0 nreloc 0 flags 0x00000000 reserved1 0 reserved2 0 If I hex dump the binary, they are aligned closely one by one with a 0x0000as separator. What I want to know is how does the loader in Mac OS X load these NSStrings when the program runs? Are they loaded simpily by recognize the 0x0000 separator or these is a string offset table elsewhere in the binary pointing to separate NSString objects? Thanks. (What I really want to do is the increase the length of one of the NSString, so I have to know how the loader recognize these separate objects)

• routing difficulty

  - by user281180

  Part of my application maps resources stored in a number of locations onto web URLs like this: http://servername/Issue.aspx/Details?issueID=1504/productId=2345 Is it possible to construct an MVC route that matches this so that I get the path in its entirety passed into my controller? Either as a single string or possibly as an params style array of strings. In my Global.aspx I have routes.MapRoute( "Issue", "Issue/{Details}", new { controller = "Issue", action = "Details" }, new { issueId = @"\d+", productId = @"\d+" } ); I have tried the code RouteValueDictionary parameters = new RouteValueDictionary { {"Controller", "Issue"},{ "action", "Details" }, { "issueId", Test.ID }, {"productId", Test.Project.ID} }; VirtualPathData vpd = RouteTable.Routes.GetVirtualPath(null, parameters); var test = vpd.VirtualPath; test value is /Issue.aspx/Details?issueId=1504&productId=3625. How to generate URLs Using ASP.NET Routing and sends it to users and they should be able to open the page by clicking on the generated link. However, here the servername isn`t included. How can I have the servername with the the link as http://servername/Issue.aspx/Details?issueID=1504/productId=2345

• How do I reference members of a single object passed to the View?

  - by Juxtaposed

  I'm new to MVC2 in ASP.NET/C#, so please forgive me if I misunderstand something. I have code similar to this in my Controller: var singleInstance = new Person("John"); ViewData["myInstance"] = singleInstance; return View(); So in my view, Index.aspx, I want to be able to reference members in that object. For example, Person has a member called Name, which is set in the constructor. In the view I want to get Person.Name from what is stored in the ViewData object. Ex.: <%= ViewData["myInstance"].name %> That doesn't work. The only real workaround I've found is to do something like this: <% var thePerson = ViewData["myInstance"]; print (or whatever the method is) thePerson.Name; %> Any help would be much appreciated... This was so much easier in PHP/Zend Framework... sigh

• App Engine - Objectify - Storing a byte[]

  - by Spines

  I'm using the Objectify library for interfacing with the app engine datastore. In my User class, I store the hashed password as a byte[]. When I put it in the datastore, it is correctly stored as a blob. When I try to load the User object back out I get this error: java.lang.IllegalStateException: Cannot load non-collection value '<Blob: 40 bytes>' into private byte[] How do I fix this? Do I have to change my User class to have the hashed password be of type ShortBlob?

• Copying blocks (ie: copying them to instance variables) in Objective-C

  - by RyanWilcox

  I'm trying to understand blocks. I get how to use them normally, when passed directly to a method. I'm interested now in taking a block, storing it (say) in an instance variable and calling it later. The blocks programming guide makes it sound like I can do this, by using Block_copy / retain to copy the block away, but when I try to run it I crash my program. - (void) setupStoredBlock { int salt = 42; m_storedBlock = ^(int incoming){ return 2 + incoming + salt; }; [m_storedBlock retain]; } I try to call it later: - (void) runStoredBlock { int outputValue = m_storedBlock(5); NSLog(@"When we ran our stored blockwe got back: %d", outputValue); [m_storedBlock release]; } Anyone have any insights? (Or, is there something I'm not getting with blocks?) Thank you very much!

• "lock request time out period exceeded" Error When Trying to See DB Hierarchies

  - by Lloyd Banks

  I have a DB that I can run basic queries (albeit much slower than normal) off of. When I try to see the hierarchy trees for tables, views, or procedures in SSMS Object Explorer, I get the "lock request time out period exceeded". My Report Server reports that run off of objects in this DB are no longer completing. Jobs associated with procedures stored on this DB also do not run. I tried using sp_who2 to find and kill all connections on the DB. This has not solved the problem. What is going on here? How can I resolve this?

• How to view existing data in Core Data?

  - by mshsayem

  Well, may be this question is silly, but I couldn't find a way (except programmatically). I built a project (for iPhone OS 3.0) which uses Core Data. The xcdatamodel file shows the schema description, but I want to see the data in tabular form (like the management studio for mssql server or phpmyadmin for mysql). Is there any way (except coding)? What is that? Also, which file (in disk/device) those data are stored into? [ I built the tutorial (from apple) on Core Data, named Locations. They used this line somewhere in the code: NSURL *storeUrl = [NSURL fileURLWithPath: [[self applicationDocumentsDirectory] stringByAppendingPathComponent: @"Locations.sqlite"]]; But, I did not see any "xxxxx.sqlite" file in project location (nor in the disk).]

• Can Google App Engine be used for "check for updated" and download binary file web service?

  - by Tofrizer

  Hi, I'm a Google App Engine newbie and would be grateful for any help. I have an iPhone app which sources data from an sqlite db stored localling on the device. I'd like to set up a Google App Engine web service which my iPhone client will talk to and check if there is a newer version of the sqlite database it needs to download. So iPhone client hits the web service with some kind of version number/timestamp and if there is a newer file, the App Engine will notify the client and the client will then request the new database to download which the App Engine will serve. Is it possible to set up a web service in Google App Engine to do this? Could anyone point me to any sample code / tutorials please? Many Thanks

• Best Application for storing code snippets

  - by Konrad

  Hi all, Just wondering if you can point me in the direction of a simple, fast program which stores code snippets. I have been using a local wiki up to now, but I find it a little annoying at times. Ideally I would like this application to be portable - i.e. it could run off of a USB stick on multiple machines with no installation. What do you guys use? EDIT: I would prefer a solution that was decoupled from the IDE and stored locally, not in the cloud. EDIT 2: Thanks for all the replies thus far, but I am still awaiting a non cloud / web based portable solution. Anyone else care to weigh in? :)

• DropDownList selectedValue not changing display

  - by MemphisDeveloper

  I have a list of controls that I change based on an event. The controls are contained within a table that is created dynamically. I traverse through a set of controls and if it is a RadioButtonList or a DropDownList I do the following: CType(cntrl, ListControl).SelectedValue = val The radio buttons set just fine but the dropdown list doesn't reset. Can anyone tell me why. The initial table is created on the first Page Load and stored in memory. It's values are changed during the eventhandling and reposted to a MasterPage's content holder.

• Trouble compiling some decompiled C# code

  - by Colin O'Dell

  I was decompiling an open-source project (because the source for the latest version hasn't been released yet). Using RedGate's Reflector tool, it gave me this block of code: if(somecondition == true) { ref Vector3i vectoriRef; float num17 = length - num; Vector3i end = vectori3; (vectoriRef = (Vector3i) &end)[1] = vectoriRef[1] - ((int) num17); } somecondition is a boolean. length and num are floats defined outside the code. vectori3 is also defined outside the code and is of type Vector3i. The type Vector3i is essentially this code, but with x, y, and z stored as integers. When I try to compile this decompiled code, I get the following errors: Line 2: Only assignment, call, increment, decrement, and new object expressions can be used as a statement Line 3: ; expected Line 3: Invalid expression term 'ref' Line 6: 'Vector3i' is a 'type' but is used like a 'variable' Any thoughts on how I can fix this code so it compiles correctly and does whatever it was intended to do?

• how to optimize an oracle query that has to_char in where clause for date

  - by panorama12

  I have a table that contains about 49403459 records. I want to query the table on a date range. say 04/10/2010 to 04/10/2010. However, the dates are stored in the table as format 10-APR-10 10.15.06.000000 AM (time stamp). As a result. When I do: SELECT bunch,of,stuff,create_date FROM myTable WHERE TO_CHAR (create_date,'MM/DD/YYYY)' >= '04/10/2010' AND TO_CHAR (create_date, 'MM/DD/YYYY' <= '04/10/2010' I get 529 rows but in 255.59 seconds! which is because I guess I am doing to_char on EACH record. However, When I do SELECT bunch,of,stuff,create_date FROM myTable WHERE create_date >= to_date('04/10/2010','MM/DD/YYYY') AND create_date <= to_date('04/10/2010','MM/DD/YYYY') then I get 0 results in 0.14 seconds. How can I make this query fast and still get valid (529) results?? At this point I can not change indexes. Right now I think index is created on create_date column

• how to tackle a custom forms database

  - by Neil Hickman

  I'm currently researching a project for the place that I work in. We are trying to create a system that will allow forms to be set up dynamically from a database. My question is what database structure would best suit something like this? I currently have a structure of: forms_form forms_formfields forms_formdata I don't think this is the most appropriate layout for this. Basically to make is make sense I need to be able to make a form within the database that can have infinite fields all customized and have the data when submitted stored in the database.

• Interpreter in C++: Function table storage problem

  - by sub

  In my interpreter I have built-in functions available in the language like print exit input, etc. These functions can obviously be accessed from inside the language. The interpreter then looks for the corresponding function with the right name in a vector and calls it via a pointer stored with its name. So I gather all these functions in files like io.cpp, string.cpp, arithmetic.cpp. But I have to add every function to the function list in the interpreter in order for it to be found. So in these function files I have things like: void print( arg ) { cout << arg.ToString; } I'd add this print function to the interpreter function list with: interpreter.AddFunc( "print", print ); But where should I call the interpreter.AddFunc? I can't just put it there below the print function as it has to be in a function according to the C++ syntax. Where and how should all the functions be added to the list?

• Custom XAML property

  - by Scott Silvi

  Hey all - I've seen a library that allows me to do this inside my XAML, which sets the visibility of the control based on whether or not the user is in a role: s:Authorization.RequiresRole="Admin" Using that library with my database requires a bunch of coding that I can't really do right now. Ultimately here's what I want to know... I have received the authenticated users role from my SPROC, and its currently stored in my App.xaml.cs as a property (not necessary for the final solution, just FYI for now). I want to create a property (dependency property? attached property?) that allows me to say something very similar to what the other library has: RequiresRole="Admin", which would collapse the visibility if the user is not in the Admin role. Can anyone point me in the right direction on this? Thanks, Scott
