You are viewing records from 08/16/2007 18:54:39 to 08/07/2008 22:13:27. I'll be adding support for selecting a date range in future.
Here I am installing SQL Server 2008 and I notice that it's installing .NET Framework 3.5 SP1.
There's a total lack of announcements so I'm not sure, but given that it's bonded at the hip with Visual Studio 2008 SP1 I am expecting it to install that next (and saw it when extracting the ISO). Only thing is it seems (updated this post after hitting this) you can't use the SP1 that is shipped with SQL server to update your normal copy of VS2k8, it only does the limited shell.
I have found what seems to be the sole blog entry over at blogs.msdn.com that has any mention of it: http://blogs.msdn.com/euanga/archive/2008/08/07/sql-server-2008-installation-confusion-vs-2008-sp1-and-netfx-3-5-sp1.aspx which seems to confirm it's the RTM version at least but it opens a can of worms by saying that you need VS 2008 SP1 and that it isn't available to install against the non-sql server bits.
Regardless of if it has been officially released, .NET 3.5 SP1 (but apparently not yet Visual Studio SP1 and all its goodness) is certainly out now anyway...
PermalinkWell the subject says it all!
MSDN subscribers can now download SQL Server 2008 - I'm sure an SQL Express 2008 edition will come out soon. Interestingly there is an extra edition available on MSDN - "Web Edition", this is pure speculation but I'm guessing this is standard edition without CALs (or SQL Express without the memory, cpu and filesize restrictions if you want to look at it that way) so you can use it on webservers.
I downloaded a copy of it this morning and will install it in a bit to try it out. Hopefully the software at work will be fine with it (we tested on an old release candidate but haven't recently) but it'll be good to have the new data types (finally we get a seperate date and time type, and the spatial data types are awesome) and an improved management studio either way.
Another feature that will be good is the ability to dictate the resources a particular database (or user) can take up, preventing a particular website or application consuming all the resources on a server.
Permalinkhttp://fantasticcontraption.com/ is quite possibly the best free web game I've encountered.
In it you get to solve complex (or seemingly simple looking) physics puzzles to move one item to another with only bars that you join together and motors (wheels in the game) that turn uncontrollably. It is then your job to make sense of these and make them do what you command! A very simple premise that rapidly gets out of control.
(Chris gets the blame for suggesting it to me and making it consume a huge amount of my free time today...)
PermalinkMy site and a bunch of hosted sites were down over the weekend due to an explosion at the datacentre where the servers are located in Houston. This is now fixed.
No e-mail was lost as the server in New York was still up, but it's still mighty annoying.
PermalinkI just encountered a small tool Microsoft released in 2005 called Log Parser 2.2. This is a tool that allows you to take literally any data format anywhere and turn it into anything, very handy - particularly when processing IIS logfiles.
The site that used to exist for it has vanished, but there's still a few good resources out there related to it:-
Alexis Eller's talk on using log parser (I couldn't find a blog for her unfortunately)
Professor Windows - May 2005 article which has a lot of good examples.
Update - I am trying to build a replacement for tools like Webalizer which aren't maintained anymore (or are insanely complex to install and configure and maintain strange files as 'summaries'). I am currently using the following command to create and maintain a multiple GB database containing an indexed set of logfiles and getting back graphs of the data instantly for display in Open Flash Chart.
The command I'm using is:
"C:\Program Files\Log Parser 2.2\logparser" "select 1, * into WebLog from <MyIISSiteNumber>" -i:IISW3C -o:SQL -server:(local) -database:NullifyDBLog -driver:"SQL Server" -createTable:ON -transactionRowCount 100 -iCheckpoint:CheckpointFile.lpc
Which is working really well, it took about 30 minutes to process 4 or 5 years of logs and now updates the database near instantly!
Watch out for the fact that LogParser isn't too bright when making tables, to do this with my log format you need to create extra indexes, I opted for indexing obvious things like date, time, the uri, the referrer, the bytes transferred and the user agent.
PermalinkJust so I don't forget, Visio UML generation is no longer available in Visual Studio 2008 out of the box; to add it back in just run the following reg file (adapted for your file paths obviously):

PermalinkI was trying to get speech recognition to work as easily as text-to-speech synthesis and noticed that there's a gotcha in that you can't use it from an MTA STA thread, so you need to invoke it on another thread. Calling BeginInvoke on an anonymous delegate instance of voidDelegate sorts this pretty easily and is a nice and brief method of avoiding the problem.
Here's the necessary code to make a blank form with two text boxes (called TextBox1 and TextBox2) do speech recognition continually. To use this code you need a reference to System.Speech.DLL and a using clause pointing to System.Speech.Recognition.
Note that hypothesized text is also displayed, so you can see the speech recognition engine 'thinking' which is handy as it lets you tell if you need to do more training with the engine.
private void Form1_Load(object sender, EventArgs e)
{
InitSpeechRecognition();
}
SpeechRecognitionEngine _recognitionEngine;
public void InitSpeechRecognition()
{
voidDelegate d = new voidDelegate(initSpeechRecognition);
d.BeginInvoke(null, null);
}
private delegate void voidDelegate();
private void initSpeechRecognition()
{
_recognitionEngine = new System.Speech.Recognition.SpeechRecognitionEngine();
_recognitionEngine.SetInputToDefaultAudioDevice();
DictationGrammar d = new DictationGrammar();
d.SpeechRecognized += new EventHandler<SpeechRecognizedEventArgs>(d_SpeechRecognized);
_recognitionEngine.UnloadAllGrammars();
_recognitionEngine.SpeechHypothesized += new EventHandler<SpeechHypothesizedEventArgs>(r_SpeechHypothesized);
_recognitionEngine.RecognizeCompleted += new EventHandler<RecognizeCompletedEventArgs>(r_RecognizeCompleted);
_recognitionEngine.LoadGrammar(d);
_recognitionEngine.RecognizeAsync();
}
void r_RecognizeCompleted(object sender, RecognizeCompletedEventArgs e)
{
BeginRecognition();
}
delegate void SpeechHypothesizedPassThroughDelegate(object sender, SpeechHypothesizedEventArgs e);
void r_SpeechHypothesized(object sender, SpeechHypothesizedEventArgs e)
{
if (this.InvokeRequired)
{
this.Invoke(new SpeechHypothesizedPassThroughDelegate(r_SpeechHypothesized), sender, e);
}
else
{
textBox2.Text = e.Result.Text;
}
}
delegate void SpeechPassThroughDelegate(object sender, SpeechRecognizedEventArgs e);
void d_SpeechRecognized(object sender, SpeechRecognizedEventArgs e)
{
if (this.InvokeRequired)
{
this.Invoke(new SpeechPassThroughDelegate(d_SpeechRecognized), sender, e);
}
else
{
//display the recognised text, or process it here
textBox1.Text += e.Result.Text + " ";
}
}
private void BeginRecognition()
{
new voidDelegate(delegate()
{
_recognitionEngine.RecognizeAsync();
}).BeginInvoke(null, null);
}
private void StopRecognition()
{
new voidDelegate(delegate()
{
_recognitionEngine.RecognizeAsyncStop();
}).BeginInvoke(null, null);
}
PermalinkI wanted to run a bunch of methods simultaneously on as many threads as possible to get the job done, but still wait at the end. I know MS have something coming to solve this, but wanted a lightweight solution, so here it is:
To use this, you simply call it with a list of delegates you want to execute, and define the return type:
The result is now valid for 100 executions but took a lot less time than 100 seconds to calculate. You could of course just be running four things at the same time, all different using this.
PermalinkThis is really simple but annoyed me for a few minutes until I got .NET Reflector up, so hopefully this will help someone else.
The render method on ASP.NET WebControl based server controls seems to be adding a span tag around the HTML output for some reason, to fix this simply override the Render method:
protected override void Render(HtmlTextWriter writer)
{
RenderContents(writer);
}
Well Microsoft have just released Windows Server 2008 and Visa service pack 1 to manufacturing. Still waiting for SQL Server 2008, but the stack is almost complete :)
Excellent features I'm looking forward to are:
- IIS 7 on a server OS!
- IPv6 file and print sharing (and oh my goodness is file and print sharing faster)
- IPv6 over VPN!!
- RDP over IPv6! (Can you tell I'm an IPv6 fan)
- Application level terminal services (like Citrix has)
- Fail back router support! If you bring one down and then back up, it doesn't keep using the failover!
- IPv6 enabled by default and not uninstallable (disabling will have to do for people who don't want to use it which should result in a lot more IPv6 compatible servers).
- Read only domain controllers - good for if the domain controller is sighted somewhere insecure.
- ADAM is now a first class citizen if you need an LDAP server but not active directory. Active directory is also no longer completely intrinsyc to the server once promoted too!
The only unfortunate thing I can see is the removal of the basic firewall and OSPF from routing and remote access, but the basic firewall has been replaced by windows firewall - I just hope you can still define rules for the other hosts in the network.
Permalink 3 CommentsThere's an article on MSDN about how to host the Windows Workflow Foundation design surface (which is a redistributable).
The example code is really complete and worth a look at, it's almost an out-of-the-box copy of just the workflow designer from Visual Studio.
If your end user requires more flexibility than most you can offer them drag-and-drop customisation of particular processes in your system (like creating a new customer could be made to go off and send details to a webservice without you, the developer; needing to get involved).
PermalinkJust a single snippet of code to work from, I included explanations in the comments. This is really a very easy to use feature in C# 3. Unfortunately you can’t create extension properties yet, but that will likely be coming soon.
namespace ExtensionMethods
{
//Note that this class is static, it must be to contain extension methods and
//it also can't reside inside another class.
public static class ExampleExtensionMethod
{
//This is the extension method
public static bool HasLetterAInIt(this string s)
{
//Just return if it contains the capital letter A as this is just an
//example
return s.Contains("A");
}
}
class Program
{
static void Main(string[] args)
{
//This will print false
Console.WriteLine("TEST".HasLetterAInIt().ToString());
//whilst this will print true
Console.WriteLine("AAHH!!".HasLetterAInIt().ToString());
}
}
}
Create a .NET 3.5 Console, Windows Forms or WPF project, add an SQL Compact Edition local database, I left the default name of Database1.sdf for the example. Just right click and open it from solution explorer and add some tables. I added two tables: Person and Pet, with a relationship between the two (right click the child table, choose properties to get the add relationship option).
Command: C:\Program Files\Microsoft SDKs\Windows\v6.0A\bin\SqlMetal.exe
Arguments: $(ItemPath) /dbml:$(ItemFileName).dbml
Initial Directory: $(ItemDir)
This is really easy and quick, but something that is handy. Getting speech synthesis to work under .NET 3.0 is really a breeze.
synth.SelectVoiceByHints(System.Speech.Synthesis.VoiceGender.Female, System.Speech.Synthesis.VoiceAge.Teen, 0);
If you’re getting the Windows Forms designer instead of the Compact Framework 3.5 designer then you likely have a problem in your registry. When you try to compile the build succeeds, but then you get the following warning:
C:\WINDOWS\Microsoft.NET\Framework\v3.5\Microsoft.CompactFramework.Common.targets : warning : An internal error occurred in PlatformVerificationTask. System.Exception: Could not locate an IAsmmetaBindingService for platform PocketPC. Check your registry settings for the platform.
C:\WINDOWS\Microsoft.NET\Framework\v3.5\Microsoft.CompactFramework.Common.targets : warning : at Microsoft.CompactFramework.Build.AsmmetaContext..ctor(String ndpversion, String platformFamily, String platformID, ICollection references)
C:\WINDOWS\Microsoft.NET\Framework\v3.5\Microsoft.CompactFramework.Common.targets : warning : at Microsoft.CompactFramework.Build.Tasks.PlatformVerificationTask.Execute()
This also manifests itself in the GetDeviceFrameworkPath entry not accepted by the schema in the “C:\WINDOWS\Microsoft.NET\Framework\v3.5\Microsoft.CompactFramework.Common.targets” file.
Well, there’s an easy enough solution to these problems, the AsmmetaBinder entries are missing from the registry in each of the sub-types under:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\.NETCompactFramework\v3.5.0.0
So here’s the entries you need to copy into notepad, save as fix.reg or similar and then double click:-
Windows Registry Editor Version 5.00

This one has been annoying me for a while now, as I do a bit of compact framework development. I simply compared two exactly similar XP machines entire compact framework installs – files, registry settings, etc till I found the differences between a working and non-working system.
There's a limit on the data sent and recieved in WCF, resulting in errors like this when the webservice sends back larger messages:
"The maximum message size quota for incoming messages (65536) has been exceeded. To increase the quota, use the MaxReceivedMessageSize property on the appropriate binding element."
The fix for this is to create a new binding with much larger limits:
System.ServiceModel.BasicHttpBinding binding = new System.ServiceModel.BasicHttpBinding();
binding.MaxBufferSize = 1024 * 1024 * 2; //bit bigger than default
binding.MaxReceivedMessageSize = 1024 * 1024 * 2;
binding.ReaderQuotas.MaxStringContentLength = 1024 * 1024 * 2;
ServiceReference1.MyServicesSoapClient client = new ServiceReference1.MyServicesSoapClient(binding, new System.ServiceModel.EndpointAddress("http://myservice/service.asmx"));
Just a reminder to myself, to let a user run an application pool without granting silly rights, you just need to run:
aspnet_regiis -ga <machine>\<user>
Which grants rights to the metabase and the temporary files folder.
PermalinkI just noticed that Visual Studio 2008 is now out to MSDN subscribers!
Unsurprisingly MSDN is struggling to work :)
PermalinkWell the subject says it all - I am indeed still around.
Trying to develop Windows Presentation Foundation applications with VS2K5 is more an exercise in suffering than getting any work done, even with Expression Blend to help.
Since it is coming out this month I should have plenty more to post at some point soon :)

Just a quick note so I can look it up easier later :) - Simply call EnableGlass(); in the Form load event and it'll change the form to support glass.
You also need to implement support for changing the colour scheme of Vista and it needs to invalidate the form after running EnableGlass - a call to this.Invalidate();
private void EnableGlass()
{
if (Environment.OSVersion.Version.Major >= 6) //check for vista
{
DwmEnableComposition(true);
DWM_BLURBEHIND d = new DWM_BLURBEHIND();
d.dwFlags = DWM_BLURBEHIND.DWM_BB_BLURREGION | DWM_BLURBEHIND.DWM_BB_ENABLE;
d.fEnable = true;
d.hRegionBlur = IntPtr.Zero;
DwmEnableBlurBehindWindow(this.Handle, d);
Paint += new PaintEventHandler(Glass_Paint);
}
}

PermalinkMSDN subscriber downloads now works in Opera, I just happened to use the wrong browser to go there and it worked great. They even suggested manually installing the file transfer manager if not running IE.
I'm impressed, congratulations to whoever at Microsoft instigated making it cross browser (or at least, not moan and stop you outright).
