HTML Tag Replacement Regex Not Quite Working Correctly?
Sep 14, 2009
This is a follow up to another question of mine. The solution I found worked great for every one of the test cases I threw at it, until a case showed up that eluded me the first time around.My goal is to reformat improperly formatted tag attributes using regex (I know, probably not a fool-proof method as I'm finding out, but bear with me).
My functions:
Public Function ConvertMarkupAttributeQuoteType(ByVal html As String) As String
Dim findTags As String = "</?w+((s+w+(s*=s*(?:"".*?""|'.*?'|[^'"">s]+))?)+s*|s*)/?>"
[code].....

I'm using VB.Net in an ASP.Net 2.0 app to run some regular expressions that remove some unnecessary markup. One of the things that I'd like to do is remove span elements that don't have any attributes in them:[code]I'd like to remove the outer span elements. Unfortunately, my regex above gives me this as a result, since the closing span matches the first one it comes across:[code]

I have some update panels on my page that do some asyncpostbacks to keep some dropdownlists correctly populated. My problem is that on my page i have an HTML input that is handling some file uploads. With the AJAX on the page with asyncpostbacks, and while i step through my code behind, the files arent being uploaded. Using a postbacktrigger (non-async) is not possible because of my layout.
Here is my code:
<div id="divFileInputs" runat="server">
<input id="file1" name="fileInput" type="file" runat="server" size="50" style="width: 50em"
onfocus="AddFileInput()" class="textbox" /></div>
[code]....
When I put a breakpoint in at the declaration of service and then check the value of "files", the count is 0. I am expecting it to be 2 when i have one file uploaded.

I am trying save a value from an input tag in some HTML source code. The tag looks like so:
<input name="user_status" value="3" />
I have the page source in a variable (pageSourceCode), and need to work out some regex to get the value (3 in this example). I have this so far: [Code] Which works fine most of the time, however this code is used to process source code from multiple sites (that use the same platform), and sometimes there are other attributes included in the input tag, or they are in a different order, eg:
<input class="someclass" type="hidden" value="3" name="user_status" />
I just dont understand regex enough to cope with these situations.

I have been making a text based noughts and crosses game and trying to convert an alpha grid reference into a number to run the logic sequence that decides whether the an input is valid. I am using the asc command to convert but it just keeps putting up the error: Conversion from string "a" to type 'Double' is not valid, when it reaches the line If (Asc(Left(choice, 1)) >= 65 And Asc(Left(choice, 1)) <= 67) Or (Asc(Left(choice, 1)) >= 97 And Asc(Left(choice, 1) <= 97))Choice is the input and has already been checked for length, whether it contains an alpha and numeric input (and where they are) and whether the numeric value is valid.

MVC3 VB.NET application. I have the below section of code in a function. This code is supposed to only fire if the handout1 is not nothing. But for some reason it is going into the then block when the handout1 is nothing in the database... I have tried a hundred different ways of checking but it is still trying to run that line of code even when there is nothing to assign to it....

I am at college and am creating an app. however i have two main problems within my app. my app is a pizza app which will allow staff within a pizza shop to send the orders to the kitchen (this is just a listbox).but, the math doesnt work, the correct pricing isnt being displayed in the label for the orders for some reason. I have tried different ways of writing and placing my code but the result is always the same. also, i have five customers per table. if i select all the customers orders and click on send, only customer two's order will be sent. not any of the other customers, but if i just do customer one on its own, it works.

I have a context menu strip associated with a listview. Everything work just fine however one of my menu options on the context menu strip has a pop-out menu (you know, you hover over the selection, and another menu strip expands out).I can seem to get these to work correctly.
Public Sub ReleasedToolStripMenuItem_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles ReleasedToolStripMenuItem.Click
FileEntries(ListViewSelectedIndex).Status = "Released"
[code]....
So I changed my sub to read as the one VB created, and still didnt work. So I went back to edit the context menu, double clicked "Reserved" menu items, then VB creates a sub w/o the _1 (like I had before).Also the check-box status for these menu items works fine.

I use the following statement to position which row to update;
Dim salonToUpdate = (From r In db.Salons _
Where r.StoreID = storeID _
Select r).Single()
If fileDate = #1/1/1900# OrElse fileDate = Nothing Then
SalonToUpdate.LastDownLoadDate = TableDate
[Code] .....
I've double checked to make sure none of the dates are invalid or null, but when the bolded statement executes, the following sql runs through the trace:
exec sp_executesql N'UPDATE [dbo].[Salons]
SET [LastDownLoadDate] = @p0
WHERE 0 = 1',N'@p0 datetime',@p0='2008-01-04 00:00:00:000'
Of course it's going to fail if LINQ is passing in where 0=1 every time. Shouldn't it be using some unique row identifier, (in my case, the salon id), to update the specific row?

i have a text box that has a max length of 5. when typeing into that text box the character input stops on the 5th character. if i set teh text property to a sting that has more than 5 characters the text box accepts the string. in vb6 i think that the text box would truncate the string to 5 characters.
does anyone know of a way to truncate, or get the text box to only accept the maxlength of the text box

[[code]I have this issue where most of the rows in the table do not fill in the data to textbox2 and any edits made in the text box when this happens do not commit to the underlying datasource.When scrolling down and back up the datarepeater different records seem to be shown each time the data on the left is correct in the standard DGV ... it's just the data repeater that doesn't work.

This issue is driving me nuts. Yesterday it was working perfectly but unfortunately I deleted the form by mistake and I had to build it again. The form contains a datagridview and I have the following code on the Load event:

I have an AsynchFileUpload on my page and for some reason when I try to use it to save the file to the server it falls. The control will allow me to select a file locally and it displays the local file path in its text box, BUT when I then click a button on my page which I am going to be using to submit all details then upload the page everything goes wrong and I get a Null Ref Exception from the AsynchFileUploader.

It seems that the filename is being lost somewhere after the button is clicked, or just never stored

I'm trying to see if the microphone on a PC is working correctly by utilizing the SpeechRecognitionEngine class.I'm using the following
VB.NET
Dim RecognitionEngine As New SpeechRecognitionEngine(New CultureInfo("en-US"))
'Dim synth As New SpeechSynthesizer
'synth.SpeakAsync("Microphone")
[code]....
When I run this code, the microphone runs until it detects a sound. If the room is silent, it never stops. At least so much as I can tell so far.But I need a way to detect when it can't detect a sound within a specified interval.I looked on MSDN and all I could find was a property called, BabbleTime. I can specify a TimeSpan that will time out the speech recognition, but from that, I can't determine if it was the timeout that caused the code to continue or if it detected sound.

I need to remove all quotes from an image tag found within lots of other text. For example, I want to make
<img src="folder/image.gif" target="_blank" />
into
<img src=folder/image.gif target=_blank />
I'm using vb, and need to use a regEx specifically for the img tag and not use replace. The img tag can be in a block of other text, so I need to use regEx to search for the <img and then within that until I meet a /> I need to remove all quotes.

I am trying to remove the tables within an HTML file, specifically, for the following document, I'd like to remove anything within the tags <TABLE....> and </TABLE>. The document contains multiple tables with texts in between.
The expression that I came up with, <TABLE.*>s*[s|S]*</TABLE>s*, however would remove the text in between the tables. In fact it would remove everything between the first <TABLE> and the last </TABLE> tags. I would like to keep the texts in between and only remove the tables.
