I need to return everything between the 2 dashes:
"xxx-12345-xxx"
Here's my conditions:
Sometimes the middle part may contain more than 5 characters, so it could look like this: "xxx-12345AB-xxx" Sometimes there's no second dash, so a string could look like this: "xxx-12345"
How can I find variables in a string of text and display them.
For instance usually I could use the * or ? characters (in ol' batch files) to mark variable character positions.
For example, I am looking for a string "Happy" & ???? & "Birthday" in a file looking for 4 characters between happy and birthday. Is there a simple way to find these characters utilizing a variable or is there a different way to do it? Would I have to declare?? as 4 specific character spaces that need to be displayed?
I have an HTML string and in that string are certain variables that I need to replace with database values. The variable names are dynamic but all begin with the characters "@@" (just two ampersands, no quotes). Is there a way to get all the words in a string that start with "@@"? I'm assuming you would use regular expressions, but not sure how to begin.

View 1 RepliesI'm having a problem recently, a logical issue so hard to determine various examples.I need the text that is inserted in textbox, which has been altered or modified or twisted to have a proper format through line accordance and constant white spaces etc. And some cases I stuck at defining the If statement within the loop. Here's an example of a text I'm trying to reformat.[code]I'm using Microsoft Visual Studio 2010 Ultimate version with Microsoft SQL Server Management Studio. This code is being fired on mouse click event of a button control. This is a snippet of my code there are more filtering after but here is what should be changed.
View 11 RepliesI'm having issues with finding something in list, and removing the item, ignoring the case of characters in string.
The code goes:
Dim listItems As New List(Of String)
Dim pattern As String = "AbC"
Dim array() As String
array = {"ABC", "abc"}
listItems.AddRange(array)
Here I'd like to remove all items from listItems, that are abc, no matter what case single characters of item are, including mixed case items. So in this example, every items should be removed
listItems.Remove(listItems.Find(Function(r) r = pattern))
If I change pattern to match the case of item, then item #2 gets removed:
pattern = "abc"
listItems.Remove(listItems.Find(Function(r) r = pattern))
How can I find item in listItems, ignoring the case characters in pattern?
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?

Sample:

Apparently I need to find out about strings and will also need to use a loop.
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 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?
View 6 RepliesI have a listbox where each line contains a short 3-4 character model number followed by a tab and then the product name the model number corresponds to. I also have a textbox which I am using to search the listbox.
The code I am using so far works somewhat, just not exactly how I would like. If I enter search text it will highlight the results in the listbox but only for the first characters, is there anyway to search the text of an entire line (index) of a listbox?
Right now I am using the following:
Private Sub txtSearch_TextChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles txtSearch.TextChanged
ListBox.SelectedIndex = ListBox.FindString(txtSearch.Text)
End Sub

Do you understand what I mean? For each two characters, the numerical character swapping place with the following letter, i.e. from 1a change it to a1.how to rearrange the numerical characters and letters in the string?

How can I add space after every 4 characters to string that returned from a function? I know the returned value it is 8 or 12 or ...etc.

I have a string value (which is a hex value) that is displayed as so...F8 30 00 3D FC 13 F8 30 00 01 31 73 34 FE 34 DE F8 30 00 3D FC 13 F8 30 00 01 31 73 34 FE 34 DE F8 30 00 3D FC 13 F8 30 00 01 31 73 34 FE 34 DEThis continues on in this exact pattern. What I am trying to do is to get a " " inserted after the first 24 characters, and then after the next 24, delete a character and place an Enter or Return value. Then I would like another " " after the next 24, and then after 24 more, delete a character and place an Enter or Return value so on until the end of the string. The format would then look like this.[code]I know this is probably done with some type of array and loop, but I'm not even sure where to get started.
View 8 RepliesI've got a program that in a nutshell reads values from a SQL database and writes them to a tab-delimited text file.The issue is that some of the values in the database have special characters (TM, dash, ellipsis, etc.) When written to the text file, the formatting is lost and they come across as junk "â„¢ or â€" etc"
When the value is viewed in the immediate window, before it is written to the txt file, everything looks fine. My guess is that this is an issue of encoding. But, I'm not real sure how to proceed, where to look, or what to look for.Is this ASCII or UTF-8? If it's one of those how do I correct it before it's written to the text file.Here's how I build the text file (where feedStr is a StringBuilder)
objReader = New StreamWriter(filePath)
objReader.Write(feedStr)
objReader.Close()

How do you change characters in a particular string and set them to a particular value.
For eg. I want to change the third character of the string "hello" to Y = > i get "heYlo".
I tried using the Chars function but it says that the function is read only.
I am just a beginner in VB programming. What if I want to check if a certain subtext is present in a string? For example, what do I code if I want to check if the word "hello" is present in a particular string or not?
