Hanselminutes Podcast 227 - Inside Expression SuperPreview with developer Mike Calvo

Scott talks to Mike Calvo, a Microsoft Lead Developer based out of Minnesota (!) about Expression SuperPreview. SuperPreview helps developers and designers with cross-browser CSS and HTML issues. How'd they build it and with what? What's inside? How does the cloud fit in and how do they support Safari? I played with SuperPreview a bit last year, but started looking at it again last month when I noticed that version 4 has introduced support for Safari on Mac via a Cloud-based Remote Service. I fired up Expression SuperPreview 4, and saw this: Then I signed up: Which enabled Mac Safari for this initial beta. I assume they'll add a pile of other browsers. If I don't see immediate browser support for ALynx, the Amiga port of Unix...(read more)

Regular Expression to Match


Here is the kind of text I want to match via a regular Expression

The id="dgSchedule" is always present in the TAG but its location may differ

The table is span over multiple line/contains white spaces/tabs...

I have the regular expression to match the start and end tag respectively over a single line

\<table .*\>


The problem is to match the whole table span over multiple lines

<table cellspacing="0" rules="all" border="1" id="dgSchedule" style="border-style:None;height:100%;width:100%;border-collapse:collapse;">
	<tr class="blackbar" align="center" style="background-color:#7FB4DE;font-family:Verdana;font-weight:bold;height:20px;">
		<td>From Place</td><td>To Place</td><td>Time</td><td>Bus Type</td>

	</tr><tr style="background-color:#DEECF5;">
	</tr><tr style="background-color:#EFF5FA;">
	</tr><tr style="background-color:#DEECF5;">


asp expression bound to user control parameter?


How can I get pass the DataKey of a GridView to a usercontol, preferably without code behind.

Why doesn't this work:

<ucOrderDetails:AJAX_OrderDetail ID="od1" runat="server" OrderNumber='<%# GridView1.SelectedValue.ToString() %>'  />

GridView1 is just a list of orders with a DataKey of OrderNumber.

od1 is not inside of a databout control, does it need to be?

Syntax error (missing operator) in query expression

Good Day Gurus!

I have a Excel user application which has a user form (named 'Registo') that displays criteria and an image that has been entered in it's corresponding spreadsheet. This works the way it should.  There's also the ability to search the spreadsheet via a form (by clicking 'Pesquisar' button) this opens a search form. However, I having a bit of a problem with it. When I try to search for something it basically doesn't do anything at all. It just sits there. So I tried to debug it and I think I'm having a problem with either the JET db engine or somethign with teh query or maybe I don't have the correct reference.

I 'borrowed' this Excel application from another forum because it's exactly what I'm looking for! However, I suck at vb.

So I was hoping somebody could take a look at the code and see if I'm missing something?  I'm kinda' desparate to get this working because I'm been trying to figure it out for days and I'm running out of time.  Cry

The file reached the maximum download limit. Check that the full text of the document can be meaning



I'm facing an issue with the indexing.

I have 1 WFE+Index server+DB server.

Index server is not installed with MS FIlter pack 1.0

When crawling, the there will be document with warning in crawl log:
The file reached the maximum download limit. Check that the full text of the document can be meaningfully crawled.

Documents that with warning are such as doc, ppt, xls, docs, ppts and many others.
However, I view into the successful crawled document, there are doucments with ext doc and ppt.

For large file index, there are MaxGrowthFactor + MaxDownLoadSize required to be added into the index server.

As my understanding is, MS Filter Pack should installed into index server(already did, correct me if i'm wrong).

I looked into the Office SharePoint Seach(CA>Services in farm), if the server is appointed to "Use this server as indexing server", then MS Filter Pack is suppose to be installed into that particular server as well.

At the bottom, there also has another option is "Use all web front end for crawling".

The question here is, IF the option "Use all web front end for crawling" is selected.
Does the WED FRONT END Server required to installed the Ms Filte

Need a regular expression


I have a required field validator for a texbox, but I just found out that the texbox can have a space in it (for a delimiter, let's say).

I checked the .net and regexlib.com, but couldn't find what I was looking for.

I simply need a regular expression that basically excepts any character string including spaces in it or even a space by itself

Can someone help me out?

Implicit-type lambda expression: is it possible?

Hi all, i was plaing around with LINQ and lambda expressions. I was trying to find duplicated files in my system. After a while a realized that duplicated could mean: - same name - same size and extension - ....   So i wrote this code: DirectoryInfo rootDirectory = ....; var groupFiles = selector => rootDirectory.EnumerateFiles("*", SearchOption.AllDirectories).GroupBy(selector).Select(g => new { g.Key, Info = g, Count = g.Count() }).Where(g => g.Count > 1); var groupsByName = groupFiles(f => f.Name); var groupsBySize = groupFiles(f => new { f.Length, f.Extension}); But i get the following error: Error 1 Cannot assign lambda expression to an implicitly-typed local variable So i tryed to make the type explicit and i realized that is not so easy. So what i'm missing?! IMPORTANT. 'm not tying to have the code working. I can solve the issue by duplicating code (even if i hate to do that) I'm rtying to improve my skills with LINQ and Lambda Expressions. Thanks all!!  

Matching set of characters via regular expression

I need to be able to match sets of quote and space characters in a string and replace these accordingly. I currently have this done in 2 lines of code, but would like to use regular expression so that I can use only 1 line of code. See below: var Qt = unescape("%22"); //quote char var Sp = unescape("%20"); //space var Cr = unescape("%0d"); //carriage return var Lf = unescape("%0a"); //line feed var CrLf = Cr + Lf;  //carriage return & line feed stringOut = stringIn.replace(Qt+Qt+Sp+Qt,Qt+Qt+CrLf+Qt); stringOut = stringOut.replace(Qt+Qt+Sp+Qt+Qt,Qt+Qt+CrLf+Qt+Qt);   I want to replace space in string like in pattern below with carriage return line feed: (in hex) 22 22 20 22 or 22 22 20 22 22. This needs to return 22 22 0D 0A 22 or 22 22 0D 0A 22 22   Line in green above will only match and replace 22 22 20 22 , but I want have regular expression into 1 line of code which  will match and replace either 22 22 20 22 or 22 22 20 22 22
