View 10 RepliesStripping HTML Function Within Text Areas Content
Mar 10, 2010I'm writing a small program that loads a folders contained file names into a list box, you then double click one of the file names listed and it appears within the programs text area where the user may freely edit it. I then have given the users options to export the data contained within the text box to a word template. What I'd like to do is add a button which the user can click in order to strip away all the html within the text areas content. I found a solution but for some reason I can't make it work. There are no errors displaying nor does the program crash out, it simply isn't doing what it should be doing.
The function I'm using is below:
Function stripHTML(ByVal strHTML)
'Strips the HTML tags from strHTML using split and join
'Ensure that strHTML contains something
If len(strHTML) = 0 Then
stripHTML = strHTML
[Code] .....
I've used the below snippet in an attempt to put the function to work in the text box.
Private Sub btnHTMLstrip_click()
' calls function stripHTML, applies to text box
richTxtBox.Text = stripHTML(richTxtBox.Text)
End Sub
So, its not working as it should?

Looking On Input For Areas To Improve?
Jul 21, 2011I'm currently in a programing class for vb.net. It's my first true exposure to OOP and I'm looking for some advice on areas where I could improve. I was wondering if someone would be willing to look at one of my programs that I have written and offer advice on areas where I can improve and things that I made much more complicated than they need to be. I'm not looking for a line by line critique just a general look at things to improve upon in the future.

Placing The Same ASP.NET Control In Different Areas Of A Page?
Feb 4, 2010I have some code that I've inherited, and it's not the greatest in the world, but it works, with one small exception:
This page is a directory search, it has controls identified by record ID, however there exists a situation where there can be more than one result with the same record ID, thus making .NET barf. I had originally implemented a check that just didn't put the control on the page, if it was already there, but we've been getting negative feedback.
My question is this: Is there a way to put the same control in two places at once, for instance having if a user checks one, the corresponding one checks as well? I'm not terribly well versed in how .NET behaves, but I'll try to provide as much additional context as possible, if needed.
EDIT: Here's the updated code that generates the controls by looping over a datatable of results
Dim cbxSendInfo As CheckBox
Dim strCheckboxID As String = "cbxSendInfo-" & drOrganizer("ID") & "-" & i
Debug.text = Debug.text & " Loading Checkbox (" &
[Code]....
Where drOrganizer("ID") is the record ID, and i is the result record number.
I know this is a terrible way to do this, at least from my background, but like I said, this is inherited code that's been hacked to pieces.
C# - Return Another PartialView That Occupy Different Areas Of My Page?
Jan 14, 2010i have an Ajax ActionLink which normally just returns a PartialView (which is just a UserControl ascx file) however, my needs have changed and i want to return another PartialView (so a total of two PartialViews) that occupy different areas of my page... of course i can't call " return PartialView("UserControl.ascx") " twice in a row consecutivelly... so my question is what would be an elegant work around for this?
how can i return two PartialViews WITHOUT wrapping these two PartialViews up in a larger parent view? i hesitate to do this because both items are in a different part of the html table which would require me to include practically the entire page in the parent view due to the structure of the table, and in this case lots of html data unnecessarily would be sent to the browser at each request - defeating the purpose of an ajax call/partial update (correct me if i'm wrong).

VS 2008 : Have A Label's Text Recorded Into A Database When Button Is Clicked?
Apr 14, 2009I would like to have a label's text recorded into a database when my button is clicked. I do not yet understand the database connection. I have created the db, and have the following

Dim Conn As String = "Provider=Microsoft.SQLSERVER.CE.OLEDB.3.5; Data Source=c: empTestDB.sdf;"

When I try to test this the .ExecuteNonQuery() becomes highlighted and says the given type name is unrecognized. My table is setup as table1 and the only 2 columns are datetime and temperature. I want the label text to go to temperature and I would like somehow the time the temperature was taken to go into the datetime field. I had the provider=microsoft.jet.oledb.4.0, but I changed it since I thought this was the one to use.
Import Text File To SQL Server 2008 Database In Real Time
Jan 31, 2012I have a machine which creates a new log file at the beginning of the day(12am) and updates the log file whenever there is any changes until the end of the day. How do I import the data in real time (30 sec, 1min or whenever there is any changes) to my SQL server database? Will SQL Server 2008 be able to access the active log file? If not will it be easier if I let my machine create a new log file whenever there is any updates? But if it is so, how do I import so many log files with different names in real time. (I must be able to scale the solution up to multiple machines).
