re: jQuery Books Review
Today @ 11:18 am | by ako

This book is deep and narrow. I am very disappointed by the coverage of the JQuery UI and other plug-ins. I expected more coverage of plug-ins and recommendations of which to use and how to use them. I browsed the TOC online and thought there was better coverage of plug-ins.
This book is good for somebody who wants to know the inner details of JQuery and develop their own plug-ins. If you want applied JQuery, look elsewhere.

re: No Preview Images in File Open Dialogs on Windows 7
Today @ 11:13 am | by Rick Strahl

Yeah still see them at times, although not that often. Then again I'm hardly ever using Explorer any more - xPlorer2 is so much better than fighting Explorer :-}

Today @ 8:33 am | by Richard

Have you seen the runaway random Explorer views in Windows 7? I used to get them all the time in Vista, but on the two machines I've upgraded to 7 and the one clean install, I haven't seen this problem once.

re: Problems with opening CHM Help files from Network or Internet
Yesterday @ 3:28 pm | by Howard

Thanks for everyones input I have solved a problem that has plagued me for a while now (at least on my home machine). Now if only I could fix this on a locked down office machine. I think this is a big enough issue that many people would stop developing CHM files.

re: Editing Applicationhost.config on 64 bit Win2008
Yesterday @ 4:55 am | by Daniel Bryars

I'm curious about the "unwanted DOS style attacks" you mentioned, makes me think I should be changing my UrlScan rules too?

Can you point me in the right direction to read up about these type attacks please?

re: DataContractJsonSerializer in .NET 3.5
Yesterday @ 12:28 am | by Maxi

for fellow programmers who encounter unexpected character. this is from microsoft connect:
Please note that DataContractJsonSerializer only supports the following encodings: UTF-8, UTF-16LE and UTF-16BE.

So, this "ms = new MemoryStream(Encoding.UTF8.GetBytes(json));" will work.

The followings are not promised to work:
ms = new MemoryStream(Encoding.Unicode.GetBytes(json));
ms = new MemoryStream(Encoding.Default.GetBytes(json));

Linq returns the whole table
Tuesday @ 7:39 pm | by Rob von Nesselrode

Hi Rick,

I've been doing some maintenance work on a heavily Linq'd middle tier and was suprised to find that it seems to always retrieve the whole table via the Datacontext.GetTable<>().

Even with you line from above:

tt_customer Tcust = context.tt_customers.Single(c => c.Pk == customer.Pk);

The whole table will be pulled into the "repository".

Am I right? or have I been in the sun too long...

Underlying this is the real question: "how to get back just one record in the first place".

Regards

Rob

re: Advanced FoxPro .NET COM Interop Article Series
Tuesday @ 7:33 pm | by Rick Strahl

Yes that should be possible. You can host a WCF service in an EXE or COM accessible assembly through VFP (although I would probably recommend using a separate EXE daemon rather than a COM hosted component for stability).

re: FireFox Slow Startup: Watch out for Browser Highlighter Plugin
Tuesday @ 12:48 pm | by Susan

In my case, after a reboot, I got an error message that popped up every 30 seconds reporting a problem with tbhdaemon.exe. That would in turn bring up 3 or 4 tell Microsoft about the problem windows. I thought for sure I had a virus. I also noticed Firefox was slow, but would never have put the two together. I removed that Highlighter add-in about an hour ago and all seems to be well now. Such a relief! Thanks so much. - Susan

re: ASP.NET ItemTemplates, EVAL() and embedding dynamic values into controls
Tuesday @ 11:15 am | by Hardik Shah

Quite well written and supported with facts and issues commonly faced by .Net guys like us. The only question remains for me is how can we use the Eval function outside Controls in the .aspx page.

re: SmtpClient and Locked File Attachments
Tuesday @ 3:31 am | by free hosting

Got a note a couple of days ago from a client using one of my generic routines that wraps SmtpClient. Apparently whenever a file has been attached to a message and emailed with SmtpClient the file remains locked after the message has been sent. Oddly this particular issue hasnt cropped up before for me although these routines are in use in a number of applications Ive built <a href="http://www.webdevforums.com/dedicated-hosting.html">dedicated server </a>. The wrapper I use was built mainly to backfit an old pre-.NET 2.0 email I built using Sockets to avoid the CDO nightmares...

re: Dynamic Delegates with Expression Trees
Monday @ 4:31 am | by Tjaart van Wijck

I this easily extensible to user a generic delegate?

What I'm looking for is a dynamic delegate wrapper for a generic method, where we start with a MethodInfo without a call to .MakeGenericMethod.

Any ideas?

Linq to SQL DataContext Lifetime Management

Good Explanation

re: Sql 2008 Management Tools: Can't save changes that require Recreation of Database
Sunday @ 7:38 pm | by David

Thanks man - this was starting to piss me off. I agree that this was something that could have been implemented better. First it could check if you even had any rows in the table before it bothered with any of the warnings. Next - the warning about data loss is cool, but they should give you the option to go ahead anyway.

re: FireFox Slow Startup: Watch out for Browser Highlighter Plugin
Saturday @ 1:05 pm | by J.

When i tried uninstalling this, YourUninstaller uninstalled almost everything in my pc. Now i got some pop`up thing with microsoft office that asks me the original installation source and it appears if i click on a folder, or if i try to get in explorer or my computer. When i start the pc, an error message appears, something about diskeeper. Opera doesn`t work, neither mozilla. What the hell happened? Oh, and system restore doesn`t work.

re: More on GZip compression with ASP.NET Content
March 05, 2010 @ 11:33 am | by Mike

Thanks for the code.

Is there an easy way to see if its working?

Trace does not show anything I can see.

Here is the vb.net code:
Public Shared Sub GZipEncodePage()

Dim Response As HttpResponse = HttpContext.Current.Response

'If (IsGZipSupported() And HttpContext.Current.Request.Path.IndexOf(".axd") = -1) Then
If (IsGZipSupported()) Then

Dim AcceptEncoding As String = HttpContext.Current.Request.Headers("Accept-Encoding")
If (AcceptEncoding.Contains("deflate")) Then
Response.Filter = New System.IO.Compression.DeflateStream(Response.Filter, System.IO.Compression.CompressionMode.Compress)
Response.AppendHeader("Content-Encoding", "deflate")
Else
Response.Filter = New System.IO.Compression.GZipStream(Response.Filter, System.IO.Compression.CompressionMode.Compress)
Response.AppendHeader("Content-Encoding", "gzip")
End If
End If

' Allow proxy servers to cache encoded and unencoded versions separately
Response.AppendHeader("Vary", "Content-Encoding")
Response.AppendHeader("Vary", "Accept-Encoding")
End Sub

Public Shared Function IsGZipSupported() As Boolean
Dim AcceptEncoding As String = HttpContext.Current.Request.Headers("Accept-Encoding")

If (Not String.IsNullOrEmpty(AcceptEncoding) And AcceptEncoding.Contains("gzip") Or AcceptEncoding.Contains("deflate")) Then
Return True
End If

Return False
End Function
