Verify String Does NOT Contain A Value Other Than Known Values
Nov 28, 2010
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 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.
my goal was to have a string generator that runs through all possible values of a string eg.
Possible values:
abcd
Chars that need to be filled:
**
Outcome:
aa ab ac

(I have cut out a section where it tries to write it to a doc file. (just the writting))What I was wondering is how would I improve several parts of this code?
1. The speed - Already In a background worker (I will write a delegate soon )
2. The chars that can be used with it because this only allows the preset ones I would like to be able to use other ones like � or Chinese chars etc.
I am trying to use string.format on a url to pass several values into the string. It's probably a simple error but I cannot get the following code to work. It doesn't even build the string.

I've created a little procedure that I use to verify if a value does actually exist. I'm currently using this all throughout my application for things such as verifying if a control's EditValue actually has a value. I was wondering if I have missed any scenarios where a value would not be available, missing, non-existent, blank, etc., and how would I incorporate in my procedure.

I have tried just about every format I have found, and I can not seem to get the string digits 0-9 to show up as "00 - 09". Now I do not want numbers 10+ to show up as 010, 011, etc. I also know there are (2) ways to format strings as well:Microsoft.VisualBasic.FormatandString.FormatI have tried all of the following with no[code]...
I doing a project for my office. In that I am showing the values and strings from a particular table based on the date range and vendor selection. It is working fine with the date range. Except within the date range if the particular reader has no data it throws an error message like dbnull string.
Lets say I have a string that could look like this[code]...
I want to break each of those in to two strings. The break point would be two decimal places to the left of the existing decimal point. So in the first example I would end up with 123 and 07.37 and the second example I would end up with 44 and 01.0. I assume I need to use a form of .indexof("."), but I cant figure it out.

Using VB.Net, I need to read the following XML from a string variable (not a file) and pull the AuthNo, Client ID, Client Name, Supplier ID, and Supplier Name for each Dispatch contained within the XML.
I have looked at tons of examples on the web using XMLReader but I can't figure out how to pull the separate ID's and match them up with their appropriate Names and also matched up with appropriate AuthNo.[code]...

Looking for the simplest way to extract values from a string. For example consider the following:Dim args As String = "/firstname:Bob /lastname:Jones"..To simplify, I need to be able to popup a box that says "Firstname = Bob" or "Lastname = Jones"
I have not been able to successfully verify a user with LDAP for an ASP.NET web application. I have done so on our own network against Active Directory, but this is against a server outside of our network that is OID (Oracle Internet Directory).Usually, I use the following code with no problem.
Dim myDirectoryEntry As New System.DirectoryServices.DirectoryEntry("LDAP://1.2.3.4:999/OU=SomeOU,DC=Something,DC=com") myDirectoryEntry.AuthenticationType = System.DirectoryServices.AuthenticationTypes.Sealing myDirectoryEntry.AuthenticationType = System.DirectoryServices.AuthenticationTypes.Secure Try

After that, I haven't been able to find a method to verify a user's log in information with their password and then pull back some information.
