Asp.net - Extract Words From A String And Verify Whether Or Not They Exist In A Database In VB
Feb 8, 2012
I am trying to create a web-method to check whether a string contains a word which is in a list of 'not allowed' words. This list will be updated from time to time.
<System.Web.Services.WebMethod()> _
Public Function checkword(ByVal Id As String) As String
Dim returnValue As String = String.Empty
[Code]...
Something is wrong with this function. It verifies the first word of string. After that it doesn't return anything.

im working with a receipt layout and trying to divide up a products descriptiontext into 2 lines if its longer then 24 characters.my first solution was something like this:
If Row.Description.Length >= 24 Then
TextToPrint &= Row.Description.Substring(0, 24) & " $100"
TextToPrint &= Row.Description.Substring(24) & vbNewLine

<div dir="ltr">SampleDataToExtract v.1.2.6.7<br /></div>
</div>

Still getting to grips with regex and have seen a few samples about that give me most of what I need so asking for opinion on this. I need to extract x words from a single line, so the regex could use w+ to get characters, however my line may contain anything inside the word like:

I am trying to verify that a string contains nothing but known values. In this case, I need to make sure it contains only "Shift", "Control", or "Alt", but not necessarily all of those. For example, these should be true: "Shift + P", "Shift + Control + H", "Alt + U; but these should not: "Other + P", "Shift + Fake + Y", "Unknown + Shift + E" etc.This is the code I tried to use:
If Not shortcut.Contains("Shift") Or Not shortcut.Contains("Control") Or Not shortcut.Contains("Alt") Then
MessageBox.Show("Invalid")
End If
I'm having difficulty wrapping my head around the needed logic to do this. I'm assuming there's a logic operator that can do this?

I have a string: Dim strXMLTags As String = "<tags><test>1</test></tags>" And I want to verify that all opening tags have a closing tag in the proper place. So if I put the previous string through, it'd work. However, if I put: Dim strXMLTags As String = "<tags><test>1</test>" Then I want it to give me an error. Is there an XML structure checker or something of the sorts? Or should I just try and load it to an XML document and if it errors then, then I know.

I have a masked text box used to create an inhouse Fips code, the first 2 characters are the state abbreviation then 3 numbers. With the format on the mtb set to LL-000, i don't need to worry about the numbers. I am trying to see if a string contains the 2 characters I need from an array, but it isn't working the way I thought it would.
Dim toUpperCase As String = mtbFipsCodeTab.Text.Trim().ToUpper()
mtbFipsCodeTab.Text = toUpperCase
Dim fipsArray() As Char ={"AK", "AL", "AR", "AZ", "CA", "CO", "CT", "DC", "DE", "FL", "GA", _
"HI", "IA", "ID", "IL", "IN", "KS", "KY", "LA", "MA", "MD", "ME",

I have a script that attempts to load XML text from a URL and I am having difficulty figuring out how to check to see if it is valid, normalized XML. I don't have a schema as there are several variables which could change the XML format, I just want to check to make sure all of the opening tags are closed properly so I can verify that the entire string loaded properly.
Here is what I have right now.
Dim objResponse As HttpWebResponse
Dim objRequest As HttpWebRequest
Dim strXml As String
Dim newMembers As New DataSet
Dim xmlReader As StringReader
[Code] .....
I would like to add something here to validate strXML
' create a dataset from the XML file pulled down from the remote server
newMembers = New DataSet()
xmlReader = New System.IO.StringReader(strXml)
newMembers.ReadXml(xmlReader)

I'm trying to write vb code to verify a password input by a user to known table passwords in access database. The form has a drop down combo box that has userID's that are selectable. I'm trying to get the index number out of the combo box selection and use that to look up what the password should be. With that information i can then compare the stored password with the password typed into the text box below the combo box. All of the examples i've found that direct me show the code in regular Visual Basic. I'm using Visual Basic 2010 with the .net architecture.

Im trying to work out what the best way to match 2 strings together, but with a difference.
String1 = "dog cat bird chair book table"
String2 = "the dog chassed the cat around the chair"
No I know I can break string1 up by space character and check if each word appears in string 2, I would prefer to not have to do that.If there some sought of regex that would take a group of words and retrun how many of them matched ?

what is the fastest way to check if Item ID exist in the database?
From what i have done, i have an excel file uploaded to datagridview, then each itemID is retrieved line by line, then accessed the database to check if ItemID exists.
Is there a way to retrieve the whole column of itemID and then query it to MSSQL2000, then display the itemIDs that does not exist.
