VS 2008 Verify 1st Two Characters Of String?
Apr 16, 2009
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",
[Code]...

I can not find the proper way to verify characters only in a text box.I am having a hell of a time trying to understand all that.I have 3 errors in my code.One error is "Error-Reference to a non-shared member requires an object reference."the other two errors are in reference to an explicit conversion from string to double.strName is what I am using as my variable for the input of the name in txtName.text Below is my full code. "----" are used to separate the classes.Attached documents are in .PDF format and HAVE TO BE FOLLOWED to the letter.Pages 2 & 3 contains the UML diagram as well as how the project should look and the structure chart for the code. I am not truly sure if my DisplayReservation is what will work to use in the list box.Is there any other reference I could get to help me understand how to use a list box as the project requires.[code]

I have a string of characters, but I would like to have a string of hexdecimal characters where the hexadecimal characters are converted by turning the original characters into integers and then those integers into hexadecimal characters. How do I do that?

So I have this
Dim a as string = "Hello"
Dim b as string()
now I want b(0) to have "H", b(1) "e", b(2) "l", and so on.
btw a changes everytime, so don't just say do b(0) = "H"

I have a string. I need to check what characters it contains because certain invalid characters are causing my sql query not to work. In the query I select where SupplierName is equal to the string. I need to replace the invalid characters at database and vb level. But I need to know first what the characters are.

I need to create a console program that allows you to enter a string, of which is then outputted in reverse.
Sample:
Input: Diewas
Output: saweiD
Apparently I need to find out about strings and will also need to use a loop.

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 need to obtain the characters of a "string" from certain word (word "Repair") and including this word. This word is never in the same position.
Example string:
"Model: Machine: abcde Repair: getthis!"
I need to get: "Repair: getthis! "
Other example
Machine: dddddd Repair: hi"
I need to get: "Repair: hi"

Not sure if too many people know this, but the following line will cause an error:
GroupName.Substring(0, 3) = "jt_"
....if the length of GroupName is less than 3 characters. I always thought it would simply return whatever characters in GroupName, but no, it errors. I must be thinking of the old VB6 days.So, I now have to change the code to:
If (GroupName.Length > 2) Then
If (GroupName.Substring(0, 3) = "jt_") Then
Note that the two comparisons need to be on separate lines. If they are on the same line, such as:
If (GroupName.Length > 2) and (GroupName.Substring(0, 3) = "jt_") Then then the code will still fail as the length command is executed at the same time as the substring command- which will cause the error when the GroupName length is less than 3.Just thought that those of us not aware of this should be!

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.

is there any function to validate if a string has only numerical characters? I can cross character for character and verify if it is a number. But I look for something simpler or if already a function like that exists.
I cannot use IsNumeric or IsDigit because it returns numbers to True with point or comma.
I need only numeric characters (no comma nor points

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.

For each character of this string I want a new character out of the string and then remove the character from the list of characters that still maybe used for other characters. It may not get the same character, you could basically just call this encryption, but it's not what I am making. I don't want to waste my time doing this one hour while VB can do this for me in <1 second.

I have written a program that uses an array of the english alphabet and Morse code. I also built a form with a input box for the alphabetic information and an output box with the Morse Code. What i am trying to do is basically type a word like "Hi" in the input box and produce the Morse Code equivalent in the Morse Code output box. [Code] This works but only one letter at a time. Do i need to Parse the string of characters one at a time, and then run it through a loop like i have created?
