.net - Converting Html Symbol Code Before Sql Insert Stmt?
Oct 24, 2011
I am trying to export some data from a SQL Express table to Access using VB.net. The data is correctly displayed in SQL as, for example, temperature with the small degree object and the letters F or C for Farenhiet or Celsius. The character is of course represented by ° = "°" in html code, which is what appears in my access tables.
How can I get the insert statements to correctly pass this symbol? I have thousands of records and this applies to maybe a hundred or so in each of a few hundred DB's I am running this conversion on.I read the data from a Gridview an .aspx .net web page and then use an insert query with an Access OLEDB connection.

I'm trying to ensure that all characters which are not numeric, or alphabetic are converted to HTML code when submitted to my database.
[Code]...
This successfully converts anything to HTML, but now I need to put some condition in there so it only does it where I need it to. ie; on any character which will either screw up my database entry, or screw up formatting when returned back to the screen as HTML (this database content is for product data for a website).
So for simplicity, I guess I want to convert only charcters which are not A-Z alphabetic or 1-0 numeric.
I could use isNumeric, but not sure how to detect alphabetic characters.
I've been Googling and found something which looked like it would work, but the logic/filtering was wrong.
So I figured I'd ask here :D

This may sound really stupid but I have to ask cause I'm not finding this answer anywhere.I have an application where the user will need to sign up for a new user account on the website [URL]..However when I am using Firefox's plug-in Firebug to view html I am getting something totally different than when I just right click on the site and view the page source.
What I am trying to do is to get the captcha from the website and display it in a picturebox on the application so the user can view the captcha, solve the captcha and then the app post is back to the service for a response.
Here is the source that I am getting using Firefox's Firebug to inspect the element:
<td>
<input type="hidden" value="Oo3Jo1I8bgzK68agMqo3s79ZZib2OkbK" name="iden">
<img class="capimage" src="/captcha/Oo3Jo1I8bgzK68agMqo3s79ZZib2OkbK.png" alt="i wonder if these things even work">
</td>
[Code]...
Why would the two be showing me two different versions of the HTML?
And how would you be able to grab that source to view in a picturebox using webclient?

'global declaration
Dim FILE_NAME As String = "EventList.txt"
Dim PATH_FILE As String = Environment.CurrentDirectory() & "" & FILE_NAME
'end of global declaration
[Code]...
Using F8 to step through all of the code, it gets to this sub, highlites Dim fs and then hit F8 again it just pops up the form, no message boxes - nothing. Other notes: EventList does exist in stated directory.
Any ideas why it wouldn't complete the sub? the first debug line after hit the f8 is: A first chance exception of type 'System.IO.FileNotFoundException' occurred in mscorlib.dll but the file is there

I am using VB.net 2003 application program. I am trying to do a select statement whereby I'm searching between 2 datetime values that are being stored as datetime. records are stored inside Access. For example, I am searching between 2 datetime:
StartTime = 2/23/2009 9:00:00 AM
EndTime = 2/23/2009 11:30:00 AM
So I need to find all the records in between 9:00 AM and 11:30 AM on 2/23/2009.
strSQL = "select OrderID from Orders Where OrderDate >= ('" & StartTime & "') AND OrderDate <= ('" & EndTime & "') "
but i got the error showing below:
An unhandled exception of type 'System.Data.OleDb.OleDBException' occurred in system.data.dll
strSQL = "select OrderID from Orders Where OrderDate >= DATEVALUE('" & StartTime & "') AND OrderDate <= DATEVALUE('" & EndTime & "') "
But when I use DATEVALUE, it takes the date from the string and set time as midnight (00:00:00). So it returns no records between 9:00 AM and 11:30 AM on 2/23/2009, but I can see there are records. [Code]
strSQL = "select OrderID from Orders Where OrderDate >= TimeValue('" & StartTime & "') AND OrderDate <= TimeValue('" & EndTime & "') "
And when I use TimeValue, it returns the time from the string and set date as jan 1st. so it returns no records between 9:00 AM and 11:30 AM on 2/23/2009, but I can see there are records. [Code]
but none of the codes above is returning records between 9:00 AM and 11:30 AM on 2/23/2009, but I can see there are records. i searched and found all those examples. but that didn't work. Is there anyway i can search between 2 datetime values. i need to find all the records that lies between that time period (for example: between 9:00 AM and 11:30 AM on 2/23/2009).

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 came across this article:[URL] It is for SQl Server driven asp.net menus. It works great but it's in C# and I want it in VB.All of the code translates fine except one:
HttpRuntime.Cache.Insert(_cacheDependencyName, new object(), dependency,
Cache.NoAbsoluteExpiration, Cache.NoSlidingExpiration, CacheItemPriority.NotRemovable,
new CacheItemRemovedCallback(OnSiteMapChanged));
I get the following error: "System.Web.Caching.CacheItemRemovedCallback is a delegate type and requires a single AddressOf expression as the only argument to the constructor". Putting in AddressOf(OnSiteMapChanged) doesn't fix it: it looks for the arguments of OnSiteMapChanged which are:Private Sub OnSiteMapChanged(ByVal key As String, ByVal item As Object, ByVal reason As CacheItemRemovedReason) Putting in them doesn;t fix it either.

I am busy with trying to convert data from an application so that it can be shown in HTML form via websites. I need to make a tree wherein I have 3 main categories each with their own sub-categories. These are the categories/sub-categories.
MENU- ParentID, ChildID, NLtitel, IconID, NLFilenaam
ROOT- ParentID, ChildID, NLtitel, IconID
SUBMENU- ParentID, ChildID, NLtitel, NLFilenaam
How I go about coding this to create my tree? I have managed to create something but am not sure if I am at all on the right lines.
Here is the little bit of code:
Public
Class Form1
Private
Sub Form1_Load(ByVal

I have the following client side code in .aspx page within a datalist itemtemplate that takes questions from the database like this:
<Itemtemplate>
<b> <%=GetQuestionNum()%>)
<%#Server.HtmlEncode(Eval("Text").ToString())%></b>
[code]....
but I'm finding it impossible to work with the html controls, i.e get their .text value from codebehind, or adding events! better way to replace the html with suitable asp.net web controls or from the codebehind and output it.

The example is in C# so i converted it using a C# to VB.NET converter and fixed a few of the conversion bugs. The code executes but fails on the line 'Throw New AviException("error for AVIFileOpen")' saying 'AVI exception unhandled'.

I have some code, that I am converting from C# to VB, in the code is the following line.
int index = ((int)document.GetCharAt(wordOffset +1)) % 256
that translates to something like this:
Dim index as Integer = CInt(document.GetCharAt(wordOffset + 1)) Mod 256
The problem is that the GetCharAt() function returns a Char type (pretty obvious from the name). VB throws an error saying that Type Char can't be converted to Type Integer. So my question is, what is the result of the explicit conversion in C# code?
