Checking String If 7 In Length And Contain Any Other Characters
Dec 3, 2011
I am working on a program that will take in a string of length 7 containing either R,G or B for the colours. The program will then check that the string if 7 in length and if it contains any other characters than R, G or B then it will be invalid. I created this code but when I enter the right string length and characters it always gives me the error for not having the right string length.
Private Sub get_cars()
Dim Letter As String
Dim valid As Boolean
Dim position As Integer
txtPosition.Text = position
[Code] ......

I'm using this code to return some string from a tcpclient but when the string comes back it has a leading " character in it. I'm trying to remove it but the Len() function is reading the number of bytes instead of the string itself. How can I alter this to give me the length of the string as I would normally use it and not of the array underlying the string itself?
Dim bytes(tcpClient.ReceiveBufferSize) As Byte
networkStream.Read(bytes, 0, CInt(tcpClient.ReceiveBufferSize))
' Output the data received from the host to the console.'
[code]....
Len() reports the number of bytes not the number of characters in the string.

MVC 3. Vb.net. Part of my app generates PDF files using Itextsharp. Some strings are too long to go onto the background image correctly. So I basically need to split this string when its over 26 characters long and when it splits it cant split in the middle of a word. from there I will use newline to add the string to the right to the next line... I did start bulding the function that I will pass the string into test for length and then pass back the string after it finishes.
Private Function stringLength(ByVal _string As String) As String
If _string.Length < 26 Then
_string.Split(
End If
End Function

I have a notify icon and I use the 'Text' property instead of 'BallonTipText' because I just like it better and it fits well with my application. The only thing wrong with that is the 64 character limit. How can I determine the length of a string, remove all characters after the 61st character, then add three periods at the end of the new string? I've looked around and can't find any solution to removing all characters after the first X characters.

Using VB or C#, I am getting a string of variable length from the database. This information is sensitive information that only certain users will be able to see.I have two cases that will use the same logic (I think).scenario 1: replace all characters with xscenario 2: replace all characters with x except the last 4 characters (assume length > 4 - this check is being done).I thought that this would be easiest using Regex.Replace(input, pattern, replacestring). As opposed to a lot of string handling with substrings and forcing a length of 'x's.

I have some code that is meant to check the length of the values in the text boxes, and if any of the boxes has no content the length of the string is 0 (or null). Here is the code:
If (Len(Form_MainScreen.Ctl48.Value) Or Len(Form_MainScreen.Ctl49.Value) Or _
Len(Form_MainScreen.Ctl50.Value) Or Len(Form_MainScreen.Ctl51.Value) Or _
[code]....
When one string is blank, the length check becomes "null" and so does the whole statement.But if the length checks are all not null, the if statement becomes a "1" and then procedes to execute the Do X procedure again.

I need to seperate a name into 2 parts using split the first part being 2 letters "That was easy" but the last part of the name would have an unknown lenght. so how do I get the unknown length? I believe I understand the Join Part here is what I have but it only works when you know the lenght of the name

If using the following in an if statement I get an error: If trg.Name.Substring(4, 6).ToUpper <> ("ABCDEF") Then I get the error: "Index and length must refer to a location within the string. Parameter name: length"
I assume this is because the string (trg.name) is too small for the 4, 6 substring. What would be the correct method of working around this problem? VB.net Studio 2008.

I am using the MaskedTextBox and I am wanting to check for the following:
1. If the length of the text = 14 characters, enable the reset and start button
2. If the length of the text < 14 characters, enable the reset button, disable the start button
3. If the length of the text = 0 characters, disable both buttons
I am able to get most of it to work but when the length = 0, the start button is disabling like it's supposed to but the reset button is staying enabled. Any ideas? I have been looking at this code for hours and can't figure out why this is.
Here is the code.
vb Private Sub mtbClientPhoneNumber_TextChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles mtbClientPhoneNumber.TextChanged 'Make sure that there is a phone number entered into mtbClientPhoneNumber. ValidateUserInput
[CODE]...
To see the form in action, you can see it here. The reset button isnt disabling when length = 0

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'm writing some code that takes a report from the mainframe and converts it to a spreadsheet. They can't edit the code on the MF to give me a delimited file, so I'm stuck dealing with it as fixed width. It's working okay now, but I need to get it more stable before I release it for testing. My problem is that in any given line of data, say it could have three columns of numbers, each five chars wide at positions 10, 16, and 22. If on this one particular row, there's no data for the last two cols, it won't be padded with spaces; rather, the length of the string will be only 14. So, I can't just blindly have
