How to change the split view when editing an aspx file

I've been using SPD 2010 more and more over the past few weeks.  However, when there's a navigation bar on the left, toolbox on the right, ribbon above and split view of code and design in the middle, there's just not enough room on the screen - (I have 2 LCDs at 1280x1024).  I can spread the window accross both monitors but that's not much use unless, I can change the split between code and design from horizontal to vertical. Is this possible?  Help apprieciated. Cheers, Bill

Defining a regular expression in the application settings xml file.


I have a little question about application settings. I have a regular expression in my code which should be customizable by the user so I made an application setting for it.  The regular expression is used in a class in the project and has the following value

Dim email_regularex As String

So now I made a new Settings file in my project and gave the following value for this string in the settings file:



So when i do this in Visual Studio 2008, Visual Studio automatically creates a app.config xml file with the right settings in it.

But when I start my application and use the regular expression like this:


 myMatch As

 Match = Regex.Match(email, email_regularex)


 myMatch.Success Then

 MsgBox("Please enter a valid email address like: iiiiii@iii.com"

, MsgBoxStyle.Critical)


the application break

Server error: is checked out or locked for editing by ... but page does not exist


I tried to rename a page in the source variation of a Publishing Site using Site Content and Structure tool, let's call it "newpage". This threw an HTTP 500 error. I then tried to rename it in SharePoint Designer. I got two message prompts, the first said:

"A file with the name Pages/newpage.aspx already exists. Do you want to replace this file?"

There is no file of that name in the Pages list in either the source or target variation. I said "Yes" and got the following error:

"Server error: The file <path>/newpage.aspx is checked out or locked for editing by ."

No user name was given in the message. I can successfully rename the page in the target variation to have the new name.

I also cannot create a new page in the source variation called newpage.aspx, I get an error saying that there is already a page of that name ... but there isn't. I have cleared the site and site collection recycle bins.

RegEx - fetching parts of file name


Hi all,

I have to admit that regular expressions is one of the topics I should learn more about...can someone help me out here? What I need is the numbers between the two underscores as one column and whatever is between the "jb" and the ".jpg" in another column. How would I go about doing this...?? ->

 ('0001_56311_jb302,086.jpg'), ('0002_212311_jb302,066.jpg'),
 ('0003_2311_jb302,046.jpg'), ('0004_11_jb302,026.jpg')

Unable to read the security policy file for trust level 'WSS_Minimal' after editing 'Alternate Ac



This is my first post, so I hope that I have picked the correct forum - it seemed the most appropriate.
I am pretty green when it comes to SharePoint admin, but as it was going so well I got a bit over-confident and tried out the 'Alternate Access Mapping'.  I didn't intend to save any changes, but I must have, because now under:

Central Administration > Operations > Alternate Access Mappings >
Edit Public Zone URLs

the 'Default' is "http://<myServer> : <port>"

and afaik there was no setting there before.  Unfortunately, I can no longer connect to http://myServer : port, although I can connect to the 'Central Administration' site on http://myServer : otherPort.  Apologies in advance for the data dump below, but if anyone has any suggestions on what I could've done (or even better what I could do to fix it before tomorrow :-) I would be very grateful.

Here are the errors that I saw/see in the browser:

Looking for a RegEx expression to eliminate extra whitespace in a line

avoid application freeze from regex.macthes using user entered expression


To my chargrin, I discovered using time limited thread  for regexMatch will not allow abort and still freeze the application.


However the freezing can be avoided despite bad user greedy expression if we precede the the matches inside the thread with


 if (!myRegex.IsMatch (...))


  // some sort state setting including message protected internal variable to indicate timeout



// then the actual matches statment

here is a sample inner class that can be used to do time limted matches

 private class MkMatchSvr


 private string sInput;

 Regex myRegex;

 protected internal string sOut;

 protected internal bool bOut;

 protected internal MatchCollection myMatch;


Regular expression to validate file path


Hello all,

Would you please share me a regular expression to validate a file path?

Note that the file path can be any valid file path {local, shared and network} as well.



File Splitter in .Net

I love to do utility programs in .Net. And this is one of them. As I was playing with JSplit (a free file splitter program), I wondered if I could do it in .Net. The framework supports file operations like reading files in bytes and creating them. It is indeed easy to do file operations in .Net Basics on File operations

Editing the Data in a GridView

In addition to deleting a GridView's underlying data, another common need is to allow end users to edit the data displayed in a GridView. With ASP.NET 1.x's DataGrid control, editing the data is certainly possible, but requires creating three event handlers and writing a dozen or so lines of code. With the GridView and ASP.NET 2.0, it is possible to create an editable GridView without writing a single line of code! All of the necessary functionality is encapsulated within the GridView.

The GridView allows editing on a row-by-row basis. An editable GridView contains an additional column with an Edit button in each row. When the end user clicks on an Edit button that row becomes editable, causing the Edit button to change to Update and Cancel buttons and the other columns to become TextBoxes. The end user can then update one or more column values and click Update to save their changes.
