• How to set post parameters in WebClient class in a Silverlight app.

  - by cmaduro

  First of all, I wrote a simple php page, that picks up some variables from the POST parameters such as a query and a authentication string, and returns the result as xml. I intend to call this page with the WebClient class from a Silverlight application. I'm using POST because we are querying the database with any valid sql statement, not only select statements. The WebClient class uses the UploadDataAsync method to post to a http server, however it requires the post parameters be passed as a NameValueCollection. This class is missing in the Silverlight runtime. How do I proceed???

• java.sql.SQLException: SQL logic error or missing database

  - by Sunil Kumar Sahoo

  Hi All, I ahve created database connection with SQLite using JDBC in java. My sql statements execute properly. But sometimes I get the following error while i use conn.commit() java.sql.SQLException: SQL logic error or missing database Can anyone please help me how to avoid this type of problem. Can anyone give me better approach of calling JDBC programs Class.forName("org.sqlite.JDBC"); conn = DriverManager.getConnection("jdbc:sqlite:/home/Data/database.db3"); conn.setAutoCommit(false); String query = "Update Chits set BlockedForChit = 0 where ServerChitID = '" + serverChitId + "' AND ChitGatewayID = '" + chitGatewayId + "'"; Statement stmt = null; try { stmt.execute(query); conn.commit(); stmt.close(); stmt = null; } Thanks Sunil Kumar Sahoo

• Selection Highlight in NSCollectionView

  - by Hooligancat

  On some occasions my head just hurts from banging it against the Cocoa wall. Today is one of those days. I have a working NSCollectionView with one minor, but critical, exception. Getting and highlighting the selected item within the collection. I've had all this working prior to Snow Leopard, but something appears to have changed and I can't quite place my finger on it, so I took my NSCollectionView right back to a basic test and followed Apple's documentation for creating an NSCollectionView here: http://developer.apple.com/mac/library/DOCUMENTATION/Cocoa/Conceptual/CollectionViews/Introduction/Introduction.html The collection view works fine following the quick start guide. However, this guide doesn't discuss selection other than "There are such features as incorporating image views, setting objects as selectable or not selectable and changing colors if they are selected". Using this as an example I went to the next step of binding the Array Controller to the NSCollectionView with the controller key selectionIndexes, thinking that this would bind any selection I make between the NSCollectionView and the array controller and thus firing off a KVO notification. I also set the NSCollectionView to be selectable in IB. There appears to be no selection delegate for NSCollectionView and unlike most Cocoa UI views, there appears to be no default selected highlight. So my problem really comes down to a related issue, but two distinct questions. How do I capture a selection of an item? How do I show a highlight of an item? NSCollectionView's programming guides seem to be few and far between and most searches via Google appear to pull up pre-Snow Leopard implementations, or use the view in a separate XIB file. For the latter (separate XIB file for the view), I don't see why this should be a pre-requisite otherwise I would have suspected that Apple would not have included the view in the same bundle as the collection view item. I know this is going to be a "can't see the wood for the trees" issue - so I'm prepared for the "doh!" moment. As usual, any and all help much appreciated.

• Emacs: selective c-auto-newline

  - by Yktula

  When c-auto-newline is set to non-nil, it re-indents the current line and inserts a carriage return and then indents the new line. However. I'm using 1TBS indent-style, which means if/else statements are made like this: if (n == 1) { exit(EXIT_SUCCESS); } else { perror("n"); } Also, I write do/while write loops like this: do { printf("%d\n", n++); } while (n < 64); As such, while I do want a newline automatically inserted after every opening brace and semicolon, I don't want newlines to be automatically inserted after an if statement or do loop is concluded with a closing brace. How can I have GNU Emacs (23.2.1, *nix) selectively insert newlines like that? Along the same lines, can I have Emacs insert an opening brace, a newline, and a closing brace on another newline, while putting the cursor in the middle of the two braces after closing parentheses following an if statement, function declaration, and the like?

• Xcode 3.2: Build & Analyze never finds any issues

  - by GamingHorror

  I've used the Clang Static Analyzer from the command line before. I wanted to try Xcode's built-in version via Build & Analyze. I never get any negative results even though i specially prepared my code with very obvious issues Clang was always able to point out: // over-releasing an object: [label release]; [label release]; // uninitialized vars, allocating but not freeing an object NSString* str; int number; CCLabel* newLabel = [[CCLabel alloc] initWithString:str fontName:str fontSize:number]; [newLabel setPosition:CGPointZero]; The result is always the same: a green checkbox, no issues. I read that C++ code can cause issues. I'm running this with cocos2d that includes box2d. Could this be a cause? Did anyone get results from Build & Analyze with the cocos2d engine? What else could it be? I also tried enabling the Static Analyzer Build Settings and then Build but the result was the same. I have restarted Xcode, cleaned all targets and emptied Xcode caches to no avail.

• ASP Classic page quit working

  - by justSteve

  I've had a set of legacy pages running on my IIS7 server for at least a year. Sometime last week something changed and now this line: Response.Write CStr(myRS(0).name) & "=" & Cstr(myRS(0).value) which used to return nothing more exciting than the string: 'Updated=true' (the sproc processing input params, stores them to a table, checks for errors and when that's all done returns a success code by executing this statement: select 'true' as [Updated] Now my pageside error handler is being involved and offers: myError=Error from /logQuizScore.asp Error source: Microsoft VBScript runtime error Error number: 13 Error description: Type mismatch Important to note that all lots of pages use the same framework - same db, same coding format, connecitonstrings and (so far as I can tell) all others are working. Troubleshot to this point: The call to the stored procedure is working correctly (stuff is stored to the given table). The output from the stored procedure is working correctly (i can execute a direct call with the given parameters and stuff works. I can see profiler calling and passing. I can replace all code with 'select 'true' as updated' and the error is the same. everything up to the response.write statement above is correct. So something changed how ADO renders that particular recordset. So i try: Response.Write myRS.Item.count and get: Error number: 424 Error description: Object required The recordset object seems not to be instantiating but the command object _did execute. Repeat - lots of other pages just the same basic logic to hit other sprocs without a problem. full code snippet set cmd1 = Server.CreateObject("ADODB.Command") cmd1.ActiveConnection = MM_cnCompliance4_STRING cmd1.CommandText = "dbo._usp_UserAnswers_INSERT" ... cmd1.CommandType = 4 cmd1.CommandTimeout = 0 cmd1.Prepared = true set myRS = cmd1.Execute Response.Write CStr(myRS(0).name) & "=" & Cstr(myRS(0).value)

• Need help understanding Generics, How To Abstract Types Question.

  - by kmacmahon

  I could use some really good links that explain Generics and how to use them. But I also have a very specific question, relater to working on a current project. Given this class constructor: public class SecuredDomainViewModel<TDomainContext, TEntity> : DomainViewModel<TDomainContext, TEntity> where TDomainContext : DomainContext, new() where TEntity : Entity, new() And its creation this way: DomainViewModel d; d = new SecuredDomainViewModel<MyContext, MyEntityType>(this.context, selectedProtectedItem); Assuming I have 20 EntityTypes within MyContext, is there any easier way to call the constructor without a large switch statement? Also, since d is DomainViewModel and I want to access methods for SecuredDomainViewModel, it seems I need to do this: if (((SecuredDomainViewModel<MyContext, MyEntityType>)d).IsBusy) But again "MyEntityType" could actually be one of 20 types. Is there anyway to write these types of statements where MyEntityType is returned from some sort of Reflection?

• python metaprogramming

  - by valya

  I'm trying to archive a task which turns out to be a bit complicated since I'm not very good at Python metaprogramming. I want to have a module locations with function get_location(name), which returns a class defined in a folder locations/ in the file with the name passed to function. Name of a class is something like NameLocation. So, my folder structure: program.py locations/ __init__.py first.py second.py program.py will be smth with with: from locations import get_location location = get_location('first') and the location is a class defined in first.py smth like this: from locations import Location # base class for all locations, defined in __init__ (?) class FirstLocation(Location): pass etc. Okay, I've tried a lot of import and getattribute statements but now I'm bored and surrender. How to archive such behaviour?

• What is better: CSS hacks or browser detection?

  - by Darryl Hein

  Commonly when I look around the Internet, I find that people are generally using CSS hacks to make their website look the same in all browsers. Personally, I have found this to be quite time consuming to find all of these hacks and test them; each change you make you have to test in 4+ browsers to make sure it didn't break anything else. About a year ago, I looked around the Internet for what other major sites are using (Yahoo, Google, BBC, etc) and found that most of them are doing some form of browser detection (JS, HTML if statements, server based). I have started doing this as well. On almost all of the sites I have worked on recently, I use jQuery, so I use the built in browser detection. Is there a reason you use or don't use either of these?

• SQL Quey slow in .NET application but instantaneous in SQL Server Management Studio

  Here is the SQL SELECT tal.TrustAccountValue FROM TrustAccountLog AS tal INNER JOIN TrustAccount ta ON ta.TrustAccountID = tal.TrustAccountID INNER JOIN Users usr ON usr.UserID = ta.UserID WHERE usr.UserID = 70402 AND ta.TrustAccountID = 117249 AND tal.trustaccountlogid = ( SELECT MAX (tal.trustaccountlogid) FROM TrustAccountLog AS tal INNER JOIN TrustAccount ta ON ta.TrustAccountID = tal.TrustAccountID INNER JOIN Users usr ON usr.UserID = ta.UserID WHERE usr.UserID = 70402 AND ta.TrustAccountID = 117249 AND tal.TrustAccountLogDate < '3/1/2010 12:00:00 AM' ) Basicaly there is a Users table a TrustAccount table and a TrustAccountLog table. Users: Contains users and their details TrustAccount: A User can have multiple TrustAccounts. TrustAccountLog: Contains an audit of all TrustAccount "movements". A TrustAccount is associated with multiple TrustAccountLog entries. Now this query executes in milliseconds inside SQL Server Management Studio, but for some strange reason it takes forever in my C# app and even timesout (120s) sometimes.

• SHA1 hashing in Delphi XE

  - by Leonardo Herrera

  Hello, I'm in the process of implementing XML digital signatures. I'm starting with little steps, so right now I want to solve the problem of SHA-1 hashing. There are lots of questions about this in SO: Digitially Sign Key with Lockbox Encryption library for Delphi Convert this php digital signing to Delphi Delphi: is there a version of LockBox for Delphi-XE Delphi 2010 Cryptography libraries ...and probably more. However, I'm using Delphi XE. So far, I've tried LockBox 2 (both the Songbeamer and Sourceforge versions), Lock Box 3, DCPCrypto2 and some others (Hashes is an easy to use unit which uses Windows crypto functions) I prepared a small test rig that gives me the following: LockBox2 FAILED: 1 ('abc') Got: '9f04f41a848514162050e3d68c1a7abb441dc2b5' Expected: 'a9993e364706816aba3e25717850c26c9cd0d89d' FAILED: 2 ('abcdbcdecdefdefgefghfghighijhijkijkljklmklmnlmnomnopnopq') Got: '51d7d8769ac72c409c5b0e3f69c60adc9a039014' Expected: '84983e441c3bd26ebaae4aa1f95129e5e54670f1' LockBox3 FAILED: 1 ('abc') Got: '9f04f41a848514162050e3d68c1a7abb441dc2b5' Expected: 'a9993e364706816aba3e25717850c26c9cd0d89d' FAILED: 2 ('abcdbcdecdefdefgefghfghighijhijkijkljklmklmnlmnomnopnopq') Got: '51d7d8769ac72c409c5b0e3f69c60adc9a039014' Expected: '84983e441c3bd26ebaae4aa1f95129e5e54670f1' DCPCrypto2 FAILED: 1 ('abc') Got: '9f04f41a848514162050e3d68c1a7abb441dc2b5' Expected: 'a9993e364706816aba3e25717850c26c9cd0d89d' FAILED: 2 ('abcdbcdecdefdefgefghfghighijhijkijkljklmklmnlmnomnopnopq') Got: '51d7d8769ac72c409c5b0e3f69c60adc9a039014' Expected: '84983e441c3bd26ebaae4aa1f95129e5e54670f1' Hashes Test 1 passes Test 2 passes Have you succeeded in compile the mentioned libraries under Delphi XE and make them give the appropriate values?

• SQL Where question

  Hi all, I have a question about case statements and nulls in a where clause. I want to do the following: Declare @someVar int = null select column1 from TestTable t where t = case when @someVar is not null then @someVar else t end Here is the problem: Let's say @someVar is null. Let's also say that column1 from TestTable t has NULL column values. Then, my condition t = t in the case statement will always evaluate to false. I basically just want to be able to conditionally filter the column based on the value of @someVar if it's provided. Any help?

• how does public key cryptography work

  - by rap-uvic

  Hello, What I understand about RSA is that Alice can create a public and a private key combination, and then send the public key over to Bob. And then afterward Bob can encrypt something using the public key and Alice will use the public and private key combo to decrypt it. However, how can Alice encrypt something to be sent over to Bob? How would Bob decrypt it? I ask because I'm curious how when I log onto my banking site, my bank sends me data such as my online statements. How does my browser decrypt that information? I don't have the private key.

• Conditional includes in Classic ASP - where the file may not exist on the server

  - by Brent

  I am currently in a situation where I have to make some additions to an application written in classic ASP using server-side JScript on IIS. The additions that I need to make involve adding a series of includes to the server-side code to extend the application's capabilities. However, the inc files may not exist on the server in all cases, so I need the application to fall back to the existing behavior (ignore the includes) if the files do not exist, rather than generating an error. I know that this can't be accomplished using if statements in the JScript code because of the way that SSI works, and have not come across any ways of dynamically including the code on the server side, where the files may not exist. Does anyone know of a way to accomplish this in classic ASP? Any help would be much appreciated.

• use of EntityManagerFactory causing duplicate primary key exceptions

  - by bradd

  Hey guys, my goal is create an EntityManager using properties dependent on which database is in use. I've seen something like this done in all my Google searches(I made the code more basic for the purpose of this question): @PersistenceUnit private EntityManagerFactory emf; private EntityManager em; private Properties props; @PostConstruct public void createEntityManager(){ //if oracle set oracle properties else set postgres properties emf = Persistence.createEntityManagerFactory("app-x"); em = emf.createEntityManager(props); } This works and I can load Oracle or Postgres properties successfully and I can Select from either database. HOWEVER, I am running into issues when doing INSERT statements. Whenever an INSERT is done I get a duplicate primary key exception.. every time! Can anyone shed some light on why this may be happening? Thanks -Brad

• How to setup a project to use TweetSharp

  - by Stuart Helwig

  I am trying to follow Pete Brown's introductory WPF tutorial which makes use of the TweetSharp libraries to interact with Twitter. I have downloaded what appears to be the latest TweetSharp binaries (and a few others including the ReleaseCandidate) from Codeplex (http://tweetsharp.codeplex.com/). No matter what references I add and no matter what using statements I try, I cannot create a reference to the TwitterService for the FluentTwitter class. I simply get the compiler error - "The type or namespace cannot be found". Now I've noticed that the TweetSharp.dll that Pete references is 518KB but the one contained in each of my different downloads is only 84kb. (I've tried several times - I am getting the full download here). The link from Pete's article to the TweetSharp libraries, no longer works (http://code.google.com/p/tweetsharp/). What basic element am I missing here or what could I be doing wrong?

• Regex for circular replacement

  - by polygenelubricants

  How would you use regex to write functions to do the following: Replace lowercase 'a' with uppercase and vice versa Where words are separated by whitespaces and > and < are special markers, replace >word with word< and vice versa Replace postincrement (i++;) with preincrement (++i;) and vice versa. Variable names are [a-z]+. Input is just a bunch of these statements. Bonus: also do decrement. Also interested in solutions in other flavors. Note: this is NOT a homework question. See also my previous explorations of regex: Regex split into overlapping strings (Alan Moore's answer is especially instructive) Can you use zero-width matching regex in String split? (my solution exploits a known Java regex bug with regards to non-obvious length lookbehind!)

• Python 'datetime.datetime' object is unsubscriptable

  - by Robert

  First, I am NOT a python developer. I am trying to fix an issue within a python script that is being executed from the command line. This script was written by someone who is no longer around, and no longer willing to help with issues. This is python 2.5, and for the moment it cannot be upgraded. Here are the lines of code in question: start_time = datetime.strptime(str(paf.Start),"%Y-%m-%d %H:%M:%S") dict_start = datetime(*start_time[:6]) end_time = datetime.strptime(str(paf.End),"%Y-%m-%d %H:%M:%S") dict_end = datetime(*end_time[:6]) When this code is ran, it generates an error with the description: 'datetime.datetime' object is unsubscriptable. This is the import statement: from datetime import datetime I have a feeling that this is something simple, but not being my native language and Google not yielding any valuable results, I am stuck. I have tried a couple of different import methods, yielding different errors, but all with these statements. Any help on this would be greatly appreciated.
