Edit The Current Regex Code To Include <script Type="text/javascript"?
Nov 16, 2011
Here is the current regex
"src=[""'](http://|./|/)?w+(.w+)*(/w+(.w+)?)*(/|?w*=w*(&w*=w*)*)?[""']>"
What I am trying to do is to grab element that is:
<script type="text/javascript" src="http://www.mysite="I need to grab everything inside these quotes">
With the current Regex I am able to grab the value but it also grabs all the "src" elements on the page.
src="http://www.mysite="I need to grab everything inside these quotes">
What I am attempting to do is to only get this one line that includes the
<script and then the src="">
And then just get the src="info from hrere" How can I edit the current regex code to include <script type="text/javascript"

I'm to .NET and all the associated cool stuff you can do, but am wondering about efficiency with User Controls and JS includes.
My user controls are mainly made up with an ascx display page and .vb.ascx code behind, as is customary with the code-behind coding style of .NET, which is great for coding simplicity although it does double then bear of files required. However, as I understand it, the server compiles these and returns the HTML efficiently.
Where the Control requires JavaScript, as I'm developing, I am making external JS files for each User Control with the same name, so the user controls consist of 'controlName.ascx, controlName.vb.ascx, controlName.js'
If a page requested by the user contains several User Controls the browser will be requesting multiple JS files, probably a master page JS file, jQuery AND each required file for the respective Controls.
This approach makes sense to me whilst developing and as everything's all kept nice and neat, making problem solving easy, but when it goes live there'll be loads of get requests from the browser, given that each time the browser gets a file, even the process of requesting the file to check if its cached or not must take some time.
Would I be best off including my JS inline in the ascx files, or code behind, directly inserting the script, or what is the 'correct' way to handle these multiple files to reduce get requests from the browser.
I'm using CSS sprites for buttons and stuff for the same reason, so wondering what to do with JS files. In my case CSS is generally handled by classes in the primary pages, so these are not an issue.

When a user clicks a button, my program checks to see if the string "Apple" exists. If it does, an "X" is added to the middle to make it "AppXle"
This is also what I want to happen:
When a user clicks a button, my program checks to see if the string "Orange" exists. If it does, the "O" and "a" are removed to make it "rnge"

I have a small program that is used for managing media libraries for some software front-ends. Basically, it reads in the files of a directory and, one-by-one, creates a new directory by each file name and moves the respective file into the new folder.Everything works well, but I am wanting to extend the functionality a bit.I would like to include multi-part file detection so that titles that are named as such:
movie-disc1.avi
movie-disc2.avi
would be moved into a single folder named movie. The files would not be renamed.As of now, I simply have an option that will allow the user to ignore certain files that match a regex pattern:
Dim m As Match = Regex.Match(IO.Path.GetFileName(filePath), "(.*?)([ _.-]*(?:cd|dvd|p(?:ar)?t|dis[ck]|d)[ _.-]*[0-9]+)(.*?)(.[^.]+)$")

Basically, I have a gridview that is opened in a new window from the parent window. It has a bunch of records with a view button to view the details of each record (which stays in the same newly opened window). I have a calendar in the parent window that accepts a Date querystring parameter to set the current date on the calendar at page load. I'm just trying to refresh the calendar in the parent window to match the date of the label in the newly opened window.
All the code below is in the newly opened window. The .Net code-behind below refers to when that view button is clicked and everything is populated. At the end, I call the js to refresh the parent window and pass the value of the LabelScheduleDate as the querystring parameter. Now the label comes through as '03/25/2010' in the code-behind, but when I pass it to the js, it comes through as '0.00005970149253731343' in the end querystring. I'm not really sure what is making the value change, and I want to pass it as just text. Do I need to pass it as a string object? I tried but I don't think I was doing it right.
JavaScript Function
function RefreshParent(inputDate) {
window.opener.location = window.opener.location + "?Date=" + inputDate;
}

alert(new RegExp(phone_check_pattern).test("test input"))

Basically what needs to happen is when the user clicks edit onto the gridview and clicks on a certain textbox a javascript calendar popups up and the user picks a date.So far, I can set it statically and the calendar works for that one row, but not the other rows since the ID changes.My ASP Code (id of textbox has been set to txtStartDate):
<asp:TemplateField SortExpression="StartDate" HeaderText="Start Date">
<EditItemTemplate>
<asp:TextBox ID="txtStartDate" onClick="ddlchange()" Runat="server" Text='<%#Bind("StartDate")%>'>
[code]....
This works, for one textbox. It does not work for other since 'ct102' changes with every row.

(Not really sure if I phrased the question correctly...) I want to create a lambda expression that would take an Object, attempt to convert it to a passed-in Type, and print to the console whether it was successful or not. At a glance, the lambda expression may seem a pretty silly way to accomplish this task, but I'd really like to know what I'm doing wrong, so I can better grow my skill set.
VS gives me a designer error about the second "T" in the expression below, telling me it isn't defined) This is where I left off:

Using the walkthrough from [URL], I implemented a DatagridView in virtual mode, totally unbound, in VB 10 Express (we are talking WinForms).
I understand that CommitEdit (DataGridViewDataErrorContexts.Commit) commits the current cell's contents to the data cache.
The example uses row-level commit, i.e. it pushes the values into a row buffer until the current row is left. Only then the row is added to (or updated in) the data store. That's exactly what I do, too.
Question -- how can I commit the current row programmatically without leaving it? (I want to commit the whole row, not just the current cell.)
If the user leaves the row, there is a RowValidating, RowValidated, RowEnter event sequence where the datastore update is taken care of. So one idea (currently my only one) was to simply re-set CurrentCell to Nothing, for example.
But I cannot just set the DataGridView's CurrentCell property to Nothing (or any cell outside of the current row) since I want to commit from within an event handler of a custom edit control created by a custom column, and I see an System.InvalidOperationException exception when setting CurrentCell there.
In fact, it is a tiny button right to a combo box, i.e. I create a DataGridViewComboBoxCell descendant which is a DataGridViewComboBoxColumn descendant's edit control. My special ComboBox cell adds a tiny button which should commit the current row. Unfortunately, that button's _Click event handler cannot change CurrentCell since DetachEditingControl throws the exception then.
Obviously, I must delay the CurrentCell re-assignment until the whole _Click event has been processed. Or what? How would I do that -- register a custom Windows message, SendMessage that one to me, and override the windows procedure of the form so it re-sets CurrentCell when this message is received? (Hello?)
There should be a rather easy way to let DataGridView commit all changes by firing the events that I handle to perform the datastore update, no?

With all new technologies like Async/Await I spent hours rewriting sample code from the published C# MSDN Articles to VB.NET.Now that Roslyn is available, why do the authors not inlude the VB.NET code. After all, it can be converted automatically. Why does MSFT not make this a requirement fo all published MSDN articles.This would save us VB.NETs lots of precious time.

I'm making a simple decoder. Type a message in the "message" text box and it spits out a code in the "code" text box. If you pop a code into the "code" text box it spits out the message in the "message" text box. Seems simple, right? Well here's my problem. I typed "The quick brown fox jumped over the lazy dog" to test it and it will put a lowercase "f" at the beginning, put letters that aren't supposed to be in there in there, and replace what should be upper case letters with lower case. I commented out the code for replacing symbols because it seemed to work fine before I put them in the code but still the same result. I checked over the code to see if I mixed stuff up. Like I accidentally put the replacement for a lower case "e" as the replacement for a lower case "h" but I can't find anything.

I am retrieving some records from a database dynamically, not knowing exactly which table I need to query, or even which fields to retrieve. I display this data in a control that looks a bit like a listbox, except each item is two lines: a label and a value. Now, the user needs to be able to browse through this list until he finds the item he needs, and then he should be able to edit the item.
This application will (eventually, this is just a 'proof of concept') run on a mobile device or PDA or something like that, so space is limited. To allow the user to edit a value, I simply show a panel containing some edit control (textbox, checkboxes, combobox, etc), let the user edit whatever he's editing, save the change and display the list of items again.[code]...

I have been using Visual Basic for about 2 weeks now so I know I am getting in over my head at this point, but times a factor. I have created a user form with around 100 User entered text boxes and pull down menus, tabbed pages etc. I can create a distributable file with no problem. However I cannot find any kind of example, tutorial, etc that will show me how to allow an end user to save the form as "enterfilenamehere.DCP" (for example) and then reopen any .dcp file created in my form application. The only examples and tutorials I can find are how to type text and save it as a txt. format. Could someone lend a complete novice some advice or point me in a good direction on where to learn about saving and opening custom file types?To clarify The user can use my form, But at this point has no way of saving and recalling what they entered in my form. It's a one time use only...not really what I want.

I have worked out how to pass my custom objects into ASP.Net json webservices. Works a charm. Problem I am having is passing in straight arrays of my custom objects or alternatively passing in arrays that are parameters of my custom objects. So for example...
Public Class WebService1
Inherits System.Web.Services.WebService
<WebMethod()> _
[code]....
Fails with error: The value "System.Collections.Generic.Dictionary`2[System.String,System.Object]" is not of type "WebApplication1.WebService1+Person" and cannot be used in this generic collection. Parameter name: value
So how do I explain to ASP.net that it is infact an array of Person? note: That changing the function to as List(of Person) or ArrayList does work but given that I implement my own custom collections this is not optimal for me.
UPDATE: Ok so what I have worked out so far is that this problem is definitely associated with how the JavascriptSerializer uses the SimpleTypeResolver to resolve types. Basically if I do something like this
Public Function AddPersonList(ByVal PersonList As String) As PersonList
I can recreate the error using the following code.
Dim PersonList As PersonList = jsonSerializer.Deserialize(Of PersonList)(PList)
However when I provide my own custom type resolver along the lines of
Dim jsonSerializer As New JavaScriptSerializer(New MyCustomTypeResolver)
I can successfully create an instance of my custom list.Now I have worked out how to provide my own custom convertor in the web.config file. Along the lines of this....
<system.web.extensions>
<scripting>
<webServices>
[code]....
PSS: I have tried to use the assembly fully qualified name as specified in the docs for the SimpleTypeResolver (SimpleTypeResolver MSDN) but this throws a "Operation is not valid due to the current state of the object." exception - which is an error caused when the TypeResolver cannot resolve the name?
My problem was never passing in a List(of Object) into my webservice (I simply posed the question as such to simplify it for stackoverflow). In such a case I would be willing to completely accept using a Generic List(of) but my problem was actually that one of my custom objects implemented a property with a strong typed List(of) so for example:
Customer {CustomerID AS Guid, FirstName AS String, LastName AS String, EmailAddresses AS EmailAddressList}
which now needs to be changed to
Customer {CustomerID AS Guid, FirstName AS String, LastName AS String, EmailAddresses AS List(Of EmailAddress)}
This is admittedly not the end of the world and is probably better in the webservice context (as you have suggested) but definitely a detriment when it comes to internal application usage of my Collection properties. What this means is that once I have this property I either need to cast it to my CustomCollectionList every time I want to use some advanced feature or I need to implement another property which exposes the CustomCollectionList.
