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 situation where a user can enter just about anything they want into a text box.Whatever they enter in the box, I need to split the string into an array of strings where each item is one word. For example, if the user enters All State Insurance, I split that into a string array:
sParams(0) = "All"
sParams(1) = "State"
sParams(2) = "Insurance"

How to correctly convert string containing upper ASCII characters to byte array besides looping through each character and filling the array using AscW(chr)?I know I can do something like:
Code:
Dim bSourceData As Byte() = System.Text.ASCIIEncoding.GetBytes(sourcedata)
But this only works for lower ascii characters (0-127).Instead of ASCIIEncoding I can specify encoding myself (System.Text.Encoding.Getencoding(encoding).GetBytes(sourcedata)). But I have to specify correct encoding in this case, otherwise most of special characters are converted to "?". What should I do if I don't know the encoding?
I'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.

Apparently I need to find out about strings and will also need to use a loop.
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!

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

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?

I need to strip every other char from an array or string. Whichever is easier.
View 4 RepliesI'm calling a Windows API that gives me a byte array which represents a unicode string - the problem is that if I call Text.Encoding.ASCII.Get String on it I just get the first letter of the string. The reason for this is that byte array has an empty byte between each character. I've verified that removing these empty bytes resolves the problem by just using a simple For loop to add the bytes that do have a value in into a new byte array, then calling Text.Encoding.ASCII.GetString on that and that gives me the full string I'm expecting.I'm just wondering if there is any easier way of getting the working string though without having to do a loop and create a new byte array etc?
