XML - How To Verify Entire String Loaded Properly
Dec 21, 2011
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 have a windows forms Application using DCOM to connect to another server in order to retrieve data from a database. The program works perfectly fine on my develeopment box both inside of and outside of the idea.However it throws an exception on my test box: System.Exception.... TYPE_E_CANTLOADLIBRARY. The error happens when accessing a property of on the the public DCOM classes. The property holds an instance of one of the private classes for the DCOM. I've compared the registries and all the relevant entries seem to be the same. When I compared the dumps I noticed that System.Config and System.XML werent loaded on the test machine, even though they are installed and appear to be in the GAC.

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 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.

I am using VB 2008 express and would like to know, If i can Replace a string inside of Javascript on page loaded into axWebBrowser so i can then execScript that function. The specific string i wish to replace is "_new" to "_self" this is so when i call the function it will load in the same page instead of popping into a new web browser. Also, is there a way I can just insert my own javascript function in the DOM as well?

I am trying to convert "-10,00" from a string into a currency using the Swedish culture. Here is my code:
ByVal ci As System.Globalization.CultureInfo("sv-SE")
Convert.ToDecimal("-10,00").ToString("C", ci)
The output from the above code is: -1.000,00 kr, which is wrong. It should be -10,00 kr. Is there anything wrong with my approach?
The solution is to pass the cultureInfo into the ToDecimal function as a second parameter.
ByVal ci As System.Globalization.CultureInfo("sv-SE")
Convert.ToDecimal("-10,00", ci).ToString("C", ci)

I'm creating an open-source web browser in VB.NET Express 2008 and I've created a User Setting named History to save a collection of strings for the browsing history. However, when I try to load the history form at runtime, only the first item (of the three I added) shows up in the listbox. Below are both examples of code I have tried to use to accomplish this task.

I am looking for a code snippet which opens a image, creates a clone of this bitmap in memory disposes this opened image so that all handles are closed.
Usually we can open a bitmap using this[code...]
the following code however keeps the Image File locked until the application is running, any suggestions how to dispose it properly. (So that no handle is left open )
Things i already tried: use dispose method of bitmap <= doesnt work (need to write implementation)
Using Block also doesnt work.

I have two rich text boxes, and two buttons on my screen. The first button grabs HTML from a URL and then converts the HTML to XML which resides in rich text box 1.
The second button is to grab the XML from the rich text box1 and then parse it to grab all the input elements by their ID.
My issue is that my parser isn't doing anything. My guess is that I'm not quite getting the XML from the first rich text box.
What would be the best way to grab the XML from a rich text box load it into memory and then parse the XML to grab all the ID tags?
Here is my code --
Imports mshtml
Imports System.Text
Imports System.Net

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.
Public Function ValueExist(ByRef CheckValue As Object) As Boolean
Try
ValueExist = True
If IsDBNull(CheckValue) Then
ValueExist = False

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
