• Protocol error in TDS stream

  - by jasonline

  What are the possible causes of this type of error - "[Microsoft][ODBC SQL Server Driver]Protocol error in TDS stream"? And how can this be fixed? My application runs in C++ calling stored procedures implemented in SQL Server. There's this one SP (containing select and update statements) that causes this problem, after which all succeeding queries will return that the cursor is in an invalid state. I've checked the SP but I don't see any possible problem.

• Having a destructor take different actions depending on whether an exception occurred

  - by dan04

  I have some code to update a database table that looks like try { db.execute("BEGIN"); // Lots of DELETE and INSERT db.execute("COMMIT"); } catch (DBException&) { db.execute("ROLLBACK"); } I'd like to wrap the transaction logic in an RAII class so I could just write { DBTransaction trans(db); // Lots of DELETE and INSERT } but how would I write the destructor for it?

• CSS Extra Small Spacing

  - by Doug

  http://www.dougymak.com/cnit133/hw8.part4.html So if you look at the tabs and look at hw2, you'll notice it has a little extra spacing that overlaps the spacing on the right. That's because wrapped the div in the <li>. You will notice the others not having it. I don't understand why is it making that extra little spacing after I wrap it. Just for the record, this is for CSS spacing which has nothing to do with the JS.

• Why build Javascript functions as JQuery plugins?

  - by Mohammad

  I've seen alot of JQuery implementations of existent JavaScript functions that merely wrap the JavaScript code in a JQuery wrapper and don't actually rely on any of JQuery's base for their operation. What are the benefits of using Javascript as a JQuery plugin? If there are none is there a speed loss to use a JQuery plugin that could have easily been implemented outside the wrapper just as well? Many thanks in advance (just trying to learn something here).

• C# Wrapping an application within another application

  - by Gio Borje

  I want to secure some applications for some people without teaching them how to add an encryption or authentication, so I thought about mocking up a simple application that launches another application if some password or authentication function returns true.

• Definition of SNMP Gauge32 vs Counter32

  - by DougN

  Can someone point me to a good definition of Gauge32 vs Counter32? I understand that Counter32 can wrap, but Gauge32 can't. I'm trying to understand their semantics. For example, I've heard you should take the difference between two Counter32 readings to get a value/second. Is there something like that for a Gauge32 value? Thanks for any insight.

• Eclipse does not format this if statement correctly

  - by Maroloccio

  This should be easy to answer: I have Eclipse set to wrap Java code over 80 chars to respect my margin. This code never wraps: if (expressionItem.type.isTypeCompatibleWith(containingNameLink.type) == false) { reportParsingError("expression type incompatible with containing " + "context."); } Question: how do I set my code formatter preferences so that the margin is respected?

• Delphi - Why does ExplicitWidth and ExplicitHeight keep appearing in .DFM files and what is it!?

  - by Pauk

  We've noticed that when checking in updates that our .DFM files have had ExplicitWidth and ExplicitHeight properties added for what appears to be no particular reason. My two questions are, what are they for and why do they get automatically added by Delphi? Below is an example with the property in: object Splitter2: TcxSplitter Left = 0 Top = 292 Width = 566 Height = 8 Cursor = crVSplit HotZoneClassName = 'TcxXPTaskBarStyle' AlignSplitter = salBottom Control = BottomPanel Color = clBtnFace ExplicitWidth = 8 end

• How do I track the method the user is looking at in VS 2010 IDE as an Addin

  - by Rob

  I have been wandering around the object model for VS 2010 and haven't been able to work out the best method for watching what the user is looking at in the main edit window. I know that each Class/method/property is broken down into its own . What I would ideally like is to hook to an event which says "The user has moved the cursor onto Project.Class.Method" and ideally "and is looking at line 4". Any suggestions?

• Which Qt classes use the disk directly?

  - by Jurily

  I'm trying to write a library to separate all the disk activity out into its own thread, but the documentation doesn't really care about such things. What I want to accomplish is that aside from startup, all disk activity is asynchronous, and for that, I need to wrap every class that accesses the disk. Here's what I found so far: QtCore: QFile QTemporaryFile QDir QFileInfo QFileSystemWatcher QDirIterator QSettings QtGui: QFileDialog QFileSystemModel QDirModel (unsure) QFont (unsure) QFontDialog I'm sure there are more.

  Writing an app that will include the ability to decompress zip and rar files. I think I'm OK on how to handle the .zips but .rars seem a little more trouble. I noticed that rarlabs has source available but it's C++. Is there a way to compile, wrap or otherwise use this code within an iPhone app? Reference: http://www.rarlab.com/rar_add.htm Open to alternate suggestions on how to handle .rar files as well. I'm still pretty much a newbie so please explain in small words :)

• Assigning a vector of one type to a vector of another type

  - by deworde

  Hi, I have an "Event" class. Due to the way dates are handled, we need to wrap this class in a "UIEvent" class, which holds the Event, and the date of the Event in another format. What is the best way of allowing conversion from Event to UIEvent and back? I thought overloading the assignment or copy constructor of UIEvent to accept Events (and vice versa)might be best.

• Why is TransactionScope using a distributed transaction when I am only using LinqToSql and Ado.Net

  - by Ian Ringrose

  We are having problems on one machine, with the error message: "MSDTC on server XXX is unavailable." The code is using a TransactionScope to wrap some LingToSql database code; there is also some raw Ado.net inside of the transaction. As only a single sql database (2005) is being accessed, why is a distributed transaction being used at all? (I don’t wish to know how to enable MSDTC, as the code needs to work on the server with their current setup)
