I’m going to be in Seattle next week for Microsoft’s annual global MVP Summit. Would love to meet some of you there - if you see me around, please say hi, or contact me if you want to sort something out in advance.

Just stumbled upon this due to some confusion about the version of PowerShell I was running on my 64 bit Vista machine. I ran PowerShell from the start menu, using the context menu to bring it up as Administrator. Then I set the execution policy to RemoteSigned:

> Set-ExecutionPolicy RemoteSigned

I ran PowerShell as a normal user (through SlickRun - brought up the 32 bit PowerShell without me noticing at first), tried to run a script and it failed. Get-ExecutionPolicy still s …

Here’s the Fest08 page, and there’s a paragraph on registration right at the top. I’ll be doing a new session there, called Handling data in F#.

Last year this one-day event was great, I’m sure it’s going to be another day full of fantastic content this year. Data today, data tomorrow is the motto this time — a great idea, I think, since almost everybody works with data in some shape or form these days. So, I hope to see you there!

I’m going to be in Galway, Cork and Dublin next week.

In Galway, I’ll do a WPF session for GMIT students on Monday afternoon, and Functional Programming in C# 3.0 in the evening at GAMTUG. If you want to be there, follow this link for all the details! On Tuesday I’m going to be in Cork, delivering a WPF session again. Here’s the link for that one — hope to see you there as well! The video is actually about my WPF introduction, but if there’s enough time, I might well do the longer _WPF in b …

I just had a weird problem — for some reason IE wouldn’t run my XAF (eXpressApp Framework) web applications (ASP.NET) anymore. At first I suspected some sort of installation problem, since I’d just installed the new 8.1.1 version, and not long ago this used to work just fine. But for some unrelated reasons I uninstalled and reinstalled, and the problem was still the same.

In the URL for the application, I tried replacing localhost with 127.0.0.1 and I found that this solved the problem. I …

I was playing around a bit today with F#, trying to write some real code that interfaces with WPF. Here are a few things I found — very much a “note to self” thing, but if you happen to be interested, please comment or ask.

Number 1 - implementing interfaces that include events is a PITA

I was trying to implement INotifyPropertyChanged, which contains the event PropertyChanged. Eventually I found a working description in this forum thread. I’ve now implemented the interface and a helper …

I just spent a little while hunting down an interesting problem in a little F# app. I had a bunch of code in a single file and I was going to structure it a bit and move certain parts into separate files. I started out from some code like this:

namespace Sturm.MyNamespace

type ICommandLine = begin
  abstract member Parts: string list
end

type IPlugin =
  abstract member CanHandle: ICommandLine -> bool
  abstract member Handle: ICommandLine -> unit

type blah =
  val mutable dummy:  ...

I recently posted about this issue I was having with a weird delay when trying to print and I thought I’d found a solution to it. But now I’ve discovered that the solution was responsible for new problems… particularly when trying to print large files (not large by numbers of pages, but by content - big scanned images or things like that), I’m suddenly getting error messages every time about timeouts.

I haven’t spent too much time trying to fix this issue, but switching the printer port back …
