• move vim cursor after a function

  - by emergence

  I'm using both the supertab and snipmate plugins. Let's say I'm using snipmate to create an if statement structure. Once I'm done adding statements inside the if-statement, how can I quickly move the cursor after the if-statement. For example: if [ $a = "b" ]; then bla; fi If my cursor is right on the semicolon and I'm in insert mode. What is the fewest number of actions I can take to move the cursor to the line after the 'fi'? If I press tab, supertab just open an autocomplete window. Thanks

• How to deal with the limited Linq Support of OData (Open Data Protocol)

  - by user341127

  I have a software, which uses a lot of Linq to SQL. Recently, I want to immigrate to OData (or WCF Data Service) architecture. But I met too many problems in Linq for the Linq support of OData is so limited. I have to modify most of my Linq statements and test them thoroughly again. I am wondering whether there is a system way to solve such a problem instead of my manual work. For example, by an external package. BTW, now I have no confidence to use OData as a kind of architecture. You are appreciated to share your ideas. Thank you in advance, Ying

• How efficient is an if statement compared to a test that doesn't use an if? (C++)

  - by Keand64

  I need a program to get the smaller of two numbers, and I'm wondering if using a standard "if x is less than y" int a, b, low; if (a < b) low = a; else low = a; is more or less efficient than this: int a, b, low; low = b + ((a - b) & ((a - b) >> 31)); (or the variation of putting int delta = a - b at the top and rerplacing instances of a - b with that). I'm just wondering which one of these would be more efficient (or if the difference is to miniscule to be relevant), and the efficiency of if-else statements versus alternatives in general.

• Why is run() not immediately called when start() called on a thread object in java

  - by pi

  Or is it? I have a thread object from: Thread myThread = new Thread(pObject); Where pObject is an object of a class implementing the Runnable interface and then I have the start method called on the thread object like so: myThread.start(); Now, my understanding is that when start() is called, the JVM implicitly (and immediately) calls the run() method which may be overridden (as it is in my case) However, in my case, it appears that the start() method is not called immediately (as desired) but until the other statements/methods are completed from the calling block i.e. if I had a method after the start() call like so: myThread.start(); doSomethingElse(); doSomthingElse() gets executed before the run() method is run at all. Perhaps I am wrong with the initial premise that run() is always called right after the start() is called. Please help! The desired again is making executing run() right after start(). Thanks.

• Using using to dispose of nested objects

  - by TooFat

  If I have code with nested objects like this do I need to use the nested using statements to make sure that both the SQLCommand and the SQLConnection objects are disposed of properly like shown below or am I ok if the code that instantiates the SQLCommand is within the outer using statement. using (SqlConnection conn = new SqlConnection(sqlConnString)) { using (System.Data.SqlClient.SqlCommand cmd = new System.Data.SqlClient.SqlCommand()) { cmd.CommandType = CommandType.Text; cmd.CommandText = cmdTextHere; conn.Open(); cmd.Connection = conn; rowsAffected = cmd.ExecuteNonQuery(); } }

• Preview result of update/insert query without comitting changes to database in MySQL?

  - by Camsoft

  I am writing a script to import CSV files into existing tables within my database. I decided to do the insert/update operations myself using PHP and INSERT/UPDATE statements, and not use MySQL's LOAD INFILE command, I have good reasons for this. What I would like to do is emulate the insert/update operations and display the results to the user, and then give them the option of confirming that this is OK, and then committing the changes to the database. I'm using InnoDB database engine with support for transactions. Not sure if this helps but was thinking down the line of insert/update, query data, display to user, then either commit or rollback transaction? Any advise would be appreciated.

• unknown column in where clause

  - by ranzy

  $result = mysql_query("SELECT * FROM Volunteers WHERE Volunteers.eventID = " . $var); $sql = mysql_query("SELECT * FROM Members WHERE Members.pid = " . $temp); I am also doing or die(mysql_error()) at the end of both statements if that matter. My problem is that the first statement executes perfectly but in that table I store an attribute called pid. So the second statement is supposed to take that and return the row where it equals that pid so I can get the name. I get an error that says unknown column in 'a2' in 'where clause' where a2 the pid attribute returned from the first statement. Thanks for any help!

• How to call constructor of the current class and parent class at the same time?

  - by Siegfried

  public class A{ public A(int a, int b) {...} } public class B : A{ List a; List b; public B(){...} //constructor1 public B(int a, int b) : base(a,b){...} //constructor2 } My question is I need to initialize both list a and b in class B. If I put them in the constructor1, how can I call constructor1 in constructor2? I don't want to rewrite the initialization statements in constructor2 again. Thanks!

  Hi I have the SQL query with c as ( select categoryId,parentId, name,0 as [level] from task_Category b where b.parentId is null union all select b.categoryId,b.parentId,b.name,[level] + 1 from task_Category b join c on b.parentId = c.categoryId) select name,[level],categoryId,parentId as item from c and I want to convert it to LINQ to SQL, yet my LINQ skills are not there yet. Could someone please help me convert this. It's the with and union statements that are making this a bit more complex for me. Any help appreciated.

• Searching algorithmics: Parsing and processing a request

  - by James P.

  Say you were to create a search engine that can accept a query statement under the form of a String. The statement can be used to retrieve different types of objects with a given set of characteristics and possibly linked to other objects. In plain english or pseudo-code using an OOP approach, how would you go about parsing and processing statements as follows to get the series of desired objects ? get fruit with colour green get variety of apples, pears from Andy get strawberry with colour "deep red" and origin not Spain get total of sales of melons between 2010-10-10 and 2010-12-30 get last deliverydate of bananas from "Pete" and state not sold Hope the question is clear. If not I'll be more than happy to reformulate. P.S: This isn't homework ;)

• MEMORY(HEAP) vs. InnoDB in a Read and Write Environment

  - by Johannes

  I want to program a real-time application using MySQL. It needs a small table (less than 10000 rows) that will be under heavy read (scan) and write (update and some insert/delete) load. I am really speaking of 10000 updates or selects per second. These statements will be executed on only a few (less than 10) open mysql connections. The table is small and does not contain any data that needs to be stored on disk. So I ask which is faster: InnoDB or MEMORY (HEAP)? My thoughts are: Both engines will probably serve SELECTs directly from memory, as even InnoDB will cache the whole table. What about the UPDATEs? (innodb_flush_log_at_trx_commit?) My main concern is the locking behavior: InnoDB row lock vs. MEMORY table lock. Will this present the bottleneck in the MEMORY implementation? Thanks for your thoughts!

• phpmyadmin and the database

  - by Jonathan

  Not sure I fully understand what phpmyadmin does. I created a database in phpmyadmin, and would now like to start accessing the data in it from php. However I have no idea where the database is? Should I export in the phpmyadmin software? I tried that but it came up with a .sql file which can be opened in notepad and contains the SQL statements used to create the datbase and the one table inside. Basically that doesn't look like a database to me.

• INSERT INTO statement that copies rows and auto-increments non-identity key ID column

  - by AmoebaMan17

  Given a table that has three columns ID (Primary Key, not-autoincrementing) GroupID SomeValue I am trying to write a single SQL INSERT INTO statement that will make a copy of every row that has one GroupID into a new GroupID. Example beginning table: ID | GroupID | SomeValue ------------------------ 1 | 1 | a 2 | 1 | b Goal after I run a simple INSERT INTO statement: ID | GroupID | SomeValue ------------------------ 1 | 1 | a 2 | 1 | b 3 | 2 | a 4 | 2 | b I thought I could do something like: INSERT INTO MyTable ( [ID] ,[GroupID] ,[SomeValue] ) ( SELECT (SELECT MAX(ID) + 1 FROM MyTable) ,@NewGroupID ,[SomeValue] FROM MyTable WHERE ID = @OriginalGroupID ) This causes a PrimaryKey violation since it will end up reusing the same Max(ID)+1 value multiple times as it seems. Is my only recourse to a bunch of INSERT statements in a T-SQL WHILE statement that has an incrementing Counter value? I also don't have the option of turning the ID into an auto-incrementing Identity column since that would breaking code I don't have source for.

• Java JPA @OneToMany neededs to reciprocate @ManyToOne?

  - by bguiz

  Create Table A ( ID varchar(8), Primary Key(ID) ); Create Table B ( ID varchar(8), A_ID varchar(8), Primary Key(ID), Foreign Key(A_ID) References A(ID) ); Given that I have created two tables using the SQL statements above, and I want to create Entity classes for them, for the class B, I have these member attributes: @Id @Column(name = "ID", nullable = false, length = 8) private String id; @JoinColumn(name = "A_ID", referencedColumnName = "ID", nullable = false) @ManyToOne(optional = false) private A AId; In class A, do I need to reciprocate the many-to-one relationship? @Id @Column(name = "ID", nullable = false, length = 8) private String id; @OneToMany(cascade = CascadeType.ALL, mappedBy = "AId") private List<B> BList; //<-- Is this attribute necessary? Is it a necessary or a good idea to have a reciprocal @OneToMany for the @ManyToOne? If I make the design decision to leave out the @OneToMany annotated attribute now, will come back to bite me further down.

• Implementation code for GetDateFormat Win32 function

  - by morpheous

  I am porting some legacy code from windows to Linux (Ubuntu Karmic to be precise). I have come across a Win32 function GetDateFormat(). The statements I need to port over are called like this: GetDateFormat(LOCALE_USER_DEFAULT, 0, &datetime, "MMMM", 'January', 31); OR GetDateFormat(LOCALE_USER_DEFAULT, 0, &datetime, "MMMM", 'May', 30); Where datetime is a SYSTEMTIME struct. Does anyone know where I can get the code for the function - or failing that, tips on how to "roll my own" equivalent function?

• iphone app hangs in AppDelegate (?)

  - by d_CFO

  No nib/IB, so I've inserted "myAppDelegate" in main and deleted the reference to main.xib in info.plist. Debug continues nicely through all five tab controllers; they seem to have gotten properly loaded into the nav controller. In fact, control passes out of the last "}" in applicationDidFinishLaunching. But there was no (visible) response back at [window addSubview:[tabBarController view]]; and [window makeKeyAndVisible]; statements, much less to the loadView within the first tab (program execution never gets there). The last line is, UIApplication _performInitializationWithURL:sourceBundleID:]. I missed a step? I executed a step improperly?

• JavaScript - question regarding data structure

  - by orokusaki

  I'm trying to calculate somebody's bowel health based on a points system. I can edit the data structure, or logic in any way. I'm just trying to write a function and data structure to handle this ability. Pseudo calculator function: // Bowel health calculator var points = 0; If age is from 30 and 34: points += 1 If age is from 35 and 40: points += 2 If daily BMs is from 1 and 3: points -= 1 If daily BMs is from 4 and 6: points -= 2 return points; Pseudo data structure: var points_map = { age: { '30-34': 1, '35-40': 2 }, dbm: { '1-3': -1, '4-6': -2 } }; I have a full spreadsheet of data like this, and I am trying to write a DRY version of code and a DRY version of this data (ie, probably not a string for the '30-34', etc) in order to handle this sort of thing without a humongous number of switch statements.

• Tracing or Logging Resource Governor classification function behavior in Sql Server 2008

  - by nganju

  I'm trying to use the Resource Governor in SQL Server 2008 but I find it hard to debug the classification function and figure out what the input variables will have, i.e. does SUSER_NAME() contain the domain name? What does the APP_NAME() string look like? It's also hard to verify that it's working correctly. What group did the function return? The only way I can see this is to fire up the performance monitor and watch unblinkingly for little blips in the right CPU counter. Is there some way I can either run it in Debug mode, where I can set a breakpoint and step through and look at variable values, or can I at least do the old-school method of writing trace statements to a file so I can see what's going on? Thanks...

• Python continue from the point where exception was thrown

  - by James Lin

  Hi is there a way to continue from the point where exception was thrown? eg I have the following psudo code unique code 1 unique code 2 unique code 3 if I want to ignore the exceptions of any of the unique code statements I will have to do it like this: try: #unique code 1 except: pass try: #unique code 2 except: pass try: #unique code 3 except: pass but this isn't elegant to me, and for the life of me I can't remember how I resolved this kind of problem last time... what I want to have is something like try: unique code 1 unique code 2 unique code 3 except: continue from last exception raised

• Best Practice to write Connection string for heavy traffic ASP.NET Web Application

  - by hungrycoder

  What is the best way to define connection string for a web application that has minimum 500 live users on the internet in terms of connection pooling. And load factors to consider? Suppose I have connection string as follows: initial catalog=Northwind; Min Pool Size=20;Max Pool Size=500; data source=localhost; Connection Timeout=30; Integrated security=sspi" as Max Pool Size is 500 and as live users exceed 500 say 520 will the remaining 20 users experience slower page load?? Or what if I have connection string as follows which doesn't talks anything about pooling or Connection time out? How the application behaves then? initial catalog=Northwind; data source=localhost; Integrated security=sspi" I'm using "Using statements" however to access the MYSQL database.

• Tool to automatically add tracing or instrumentation to an .NET app?

  - by Tony_Henrich

  I have a .NET app which runs once a day. Sometimes there's a logical error somewhere which occurs randomly. Is there a tool like Eqatec's Tracer which automatically injects instrumentation in the code and logs everything to a file? The issue with Eqatec's Tracer is that it opens a window on the machine and it doesn't seem to log. My issue rarely occurs and I need to keep all logs for a long time. I don't want to change the source code and add logging statements all over the place. I am aware of PostSharp & Logfaces.

• Sharing some info with all DLLs pulled into a process

  - by JBRWilkinson

  Hi all, We've got an Enterprise system which has many processes (EXEs, services, DCOM servers, COM+ apps, ISAPI, MMC snapins) all of which make use of many COM components. We've recently seen failures in some of the customer deployments, but are finding it hard to troubleshoot the cause. In order to track down the problem, we've augmented the entire source with logging statements where errors occur. In order to identify which logs came from what processes, the C++ logging code (compiled into all components) uses the EXE name to name the log. This is good for some cases, but not all - COM+ apps, ISAPI and MMC snapins all have system EXE names and the logs end up interleaved. I saw this post about shared data sections which might help, but what I don't understand is who decides what goes in the shared section. Is there any way I can guarantee that a particular piece of code writes into the shared section before anyone else reads it? Or is there a better solution to this problem?

• Errors/Warnings/Debug Info no longer appears in Debug Console

  - by Alex L

  Hi Guys: This one is driving me crazy. When I run my App and open the Debug Console there is nothing there! Nope, not even the output from my NSLog statements. Before I would see a bunch of debug information starting with [Session Started ...] and ending with 'Terminating in response to SpringBoard's termination'. The Status Bar at the bottom of the Console says my App was successfully launched. Even Errors and Warnings from my code no longer appear. How do I get this to show up again? Any help would be greatly appreciated.

• code-style: Is inline initialization of JS objects ok?

  - by michael

  I often find myself using inline initialization (see example below), especially in a switch statement when I don't know which case loop will hit. I find it easier to read than if statements. But is this good practice or will it incur side-effects or a performance hit? for (var i in array) { var o = o ? o : {}; // init object if it doesn't exist o[array[i]] = 1; // add key-values } Is there a good website to go to get coding style tips?
