Yesterday we started our performance testing of our latest application and found one query taking 16 sec to execute. Using a combination of SQL profiler and JetBrains dotTrace (I blog on that later – it deserves it) We narrowed the problem down to not an ill performance SQL query but actually the built in CBO.FillCollection…
Just announced that a new major release of virtual earth will happen on the 7th of November. No details of the changes yet but it is a good thing that the guys let us know so we can be prepared to update our apps next week. What features will we see? They were playing with…
Well i got my new 9400 Dell lappy. Only problem is, has the 9300, which from the outside looks pretty much identical, and we both have tech ed backpacks so the chances of us taking the wrong lappy is kinda high. So how did we solve this you might ask….with stickers of course
Implement .NET Framework interfaces to cause components to comply with standard contracts. (Refer System namespace) • IComparable interface, IComparable Generic – V2 • IDisposable interface – version breaking change to add this to a class• IConvertible interface – converts objects to value type• ICloneable interface • IEquatable<T> interface – V2 Generalised compare different objects• IFormattable interface – cultural ToString()
Improve type safety and application performance in a .NET Framework application by using generic collections. (Refer System.Collections.Generic namespace) all V2 classes pretty much impmented as generic versions of the 1.1 classes. Faster because there is no boxing/unboxing• Collection.Generic interfaces • Generic Dictionary • Generic Comparer class and Generic EqualityComparer class • Generic KeyValuePair structure • Generic List class, Generic List.Enumerator…
Manage a group of associated data in a .NET Framework application by using collections. (Refer System.Collections namespace) • ArrayList class – implements IList• Collection interfaces ICollection – defines size, enumerators, and syncronisation of collections IComparer – used with Array.Sort and Array.BinarySearch. Allows customisation of sort order of a collection IList– collection of objects accessed by index IEnumerable – exposes enumerator, for…
Manage data in a .NET Framework application by using .NET Framework 2.0 system types. (Refer System namespace) • Value types (bool, byte, char, decimal, double, enum, float, int long, sbyte, short, struct, uint, ulong, ushort) • 2 categories – structs ( numeric types, bool, user defined) – enums Derived from System.ValueType. Cannot contain null. Implicit default constructor that intialises default value. Assigning one…
I now face the problem of contact on 4 different instant messenger clients….MSN Messenger, Google Talk, Skype and now ICQ (for my new job). I started looking at Meebo which allows me to log into 3 of the 4 at once without having to install yet another client and it’s looking ok so far. Least it means…
To add an attribute by code in Infopath: IXMLDOMNode expressionBox= _document.DOM.selectSingleNode(“//someNode”); IXMLDOMNode disableEditing; node2 = _document.DOM.createAttribute(“disableEditing”); node2.text = “yes”; addressNode.attributes.setNamedItem(node2);
I installed Vista RC2 when it was first released and have been struggling with performance using a Dell 9300 with1GB RAM, 7200 HDD, 2Ghz M cpu, 6800go GPU. Today my new RAM arrived from AusPCMarket – 2 sticks of Corsair DDR2 1GB. What a difference it has made. Now can say from experince get at…
We came across a problem with InfoPath 2003 the other day. We use a lot of expression boxes to display read-only data, and happened across the fact that we can select them, type in them, and then save the data . All very scary when it’s meant to be READ ONLY! Only thing i’ve found…
Testing the child blog feature….

I purchased a Logitech headset today and enabled vista speech recognition. It is very cool and yet a little bit frustrating. Unfortunately although I can start a new blog entry completely using my voice I couldn’t Dictates directly into the text box control. had to start notepad. All I need now is for the cursor…
For those who don’t know…the main expressway for Brisbane peak hour traffic has been closed. Read more about it here. Because my bus seems to use the roads everyone else does it too a few hours to get to work the other day instead of 1/2 hour. So i’ve been getting dropped at the train….
IIS7 provides a tighter integration with ASP.NET that will let us do some very cool things like friendly urls, file security etc. In order to get DNN to run I had to make a few changes: 1. Turn on IIS7. Seem like an obvious one i know. Its in Control panel -> Programs -> Turn…
We went out to Beaudesert today to take some action shots of the RTCB motorX. I was itching to use the built in movie maker in Vista RC2 so check it out courtesy of YouTube. See the photos here.
Went to the 2nd VSTS Tech Brekkie today. Greg did a great session on Introduction to Visual Studio Team Edition for Database Professionals. As usual he did a great session. The db stuff is looking pretty cool esp the testing etc. Looking forward to the next sessions….
Saw this on news.com. http://www.news.com.au/story/0,23599,20555319-13762,00.html Funny how some people will follow instructions that are obviously incorrect and the instinct to live doesn’t kick in.
I downloaded, installed and transfered all my bugs from excel to a proper bug tracker today in 15mins flat. The application is called BugTracker.Net, it’s free, and runs in IIS using SQL server for the database. Installation couldn’t have been easier. Simply unziped, setup a website pointing to that folder, created a database, set the connection…
So i’ve gone and knocked my ipod cable out when it was connected to the pc…when it has the “Do not diconnect” message on. Normally this is ok..but on this occasion it was busted. Tried replugging in and everything i could think of…was starting to think i’d have to wait for it to run outta…
