What code can I use to trim a word from a string in Visual Basic.NET?
for example, If I had the following string: Dim str As String = "Hello World"
And I want to trim this string so it only displays "Hello"
I have tried a few trim functions but can;t work it out.
I have a large text field taken from a databasers.Item("content")How can I limit this to say 100 characters but not cut off the last word. eg "limit this to 100 cha..."
View 5 RepliesI'm working with this new API that returns some XML. The problem is that the developer has chosen to indent his returned XML and it's driving me nuts. So, I thought I'd just trim it and then use it that way. But it's not working. here is what I'm getting back from the API:
<response>
<result>success</result>
<session_guid>33434343556</session_guid>
</response>
The code, of course, comes back in a StreamReader object called reader. So my plan is to write the UNTABBED XML to a text file. I thought this would work:
dim output as String = reader.ReadToEnd()
dim xml as String
'open the file in a try/catch statment. Won't include that here
....
....
'Now, we're going to remove whitespace using String.Trim() and write it to a file:
xml = output.Trim()
Then I close the file and move on. The problem is that the String.Trim command isn't working! When I open the file, the indentations ARE STILL THERE and it's throwing everything off.
I have this string that shall come in from another file. The string has maximum length of 102 digits. I need to compare the string with numbers in a pair and delete those from that string.
e.g - 6125223659587412563265... till 102
numbers that compare with this string-
first set - 61
new string = 25223659587412563265
second set - 36
new string = 252259587412563265
and so on. the set of numbers shall go to maximum of 51 pairs = 102, which shall give an end result of string = "" How can i achieve this in a loop?
this is not answer, this is editing the question. i dont know why but the edit button just vaniashed so i have to edit question here. No duplicates will ever be in this string. and in the end when compares are done, i want to see what numbers are left in pairs.

I'm working in Microsoft Access attempting to concatanate the results of a query into a single string. The code looks like this:rtn = Trim(rs.Fields(0).Value) Trim$(rs.Fields(1).Value)When I display the string in a list box, I only see the value for Fields(0) I cannot see the value for Fields(1).When I run the code in debug mode, I can see the value of rtn and it contains these non-alphanumeric boxes like this:"Earth4[] Admin[]" (where [] indicates the non-alphanumeric character)What can I do to cleanup the string, remove the [] and then display in my list box?

I have a DGV and a button to open a browser window to an ip address and also a button to open the ip address gateway. I can open the ip address that is displayed in the DGV no problem. What I am stuck on is opening the gateway address. So for example I click a record in DGV then the button and my browser opens to 10.15.2.248 What I need to do is replace 248 with 1 The ips will all end differently though for example 10.20.2.34 , 10.256.34.4 and so on. So as far as I know I will have to trim to the last period and add a 1 How can I do this?
View 4 RepliesI'm trying to write a function to find a word in a string in the this format : "ThisissometextthatIneedtofindandthisisthetext. This is another text."It's read as " This is some text that I need to find and this is the text. This is another text." but there is no space between each word. I want to get the word "text" or any word in that string. Can you help me with this function with a code sample ?
And I think that this method can be implemented with a string of Unicode also because in a sentence of Unicode it contains one or few, sometimes zero spaces between each word.
If you assign a string that is longer than the current value of the MaxLenght property, VB6 automatically trims the value to MaxLength characters, whereas VB.NET doesn't. Is there any way to achieve the same in VB.Net.
View 1 RepliesI'm receiving a byte array from a network device by using the TcpClient class and as I have no idea how much data will be being sent I have to just declare a buffer that is X number of bytes long and keep reading into that until I've got all of the data. I then convert this byte array to a string using Text.Encoding.ASCII.GetString but the problem is that this gets any null bytes that were at the end of the buffer after the string and it includes them in the string. This then means when I do String.EndsWith it doesnt work as I would expect it to because there are just loads of 0 bytes at the end of the string.
Once I had realised that was what was happening (which took a long time as these null bytes are completely invisible when you are looking at the data in String form) I thought fine I'll just use Trim on the string but I've found that this doesnt make any difference at all. I thought Trim was supposed to remove any blank space from the start/end of a string, which I assumed would include empty bytes as well.
So is there any alternative I can use that will trim the empty bytes off the end or do I have to do it the 'manual' way and loop through my byte array before converting it to string and remove any null bytes? One thing that has just popped into my head as I'm typing this is to try using the Chr method and pass it 0 and combine that with Trim like so:

I am trying to create a function that searches each line of a richtextbox and returns that row if one of many search phrases are found.The app works wonderfully when used with longer words or muli word phrases as the search criteria.The problem I have is if the search word/ criteria contains a small string such as bae or sp then I get alot of false positives. Anytime bae or sp is found within any word it returns the results.I need the function to stop looking within the words for results and instead look at the word as a whole for a match.Below you can see that I am taking each line of text in the richtextbox, removing most non-alpha numberic characters and replacing them with spaces.Then I have it remove any double spaces with single spaces.For the search term list I have it take the text before the delimiter;and do the same.Trouble I am having is,if the search term is SP and the search phrase is "This is a space shuttle lauch"it will return the sentence since the sentence contains the word "space" which starts with sp.[code]

Problem: Your task is to take input from the user in string and give the following options to the user in a menu.
1- Find a String
2- Create sub-string
3- Erase a portion of a sting
4- Replace a word in the string
5- Count number of words and characters in the string without spaces.
6- Capitalize first character of each new sentence and convert the rest
of the characters to lower case.
7- Sort all the words in alphabetical order. (Use Bubble sort algorithm to perform sorting).
To perform all the above mentioned tasks you can only use pointers. Create a function to perform every task.
For example:
(1).SomeFunction().Equals("one")
(2).SomeFunction().Equals("two")
I really only need it for digits 1-9 in the case I'm working with, should I just use a switch/select case?

I already try using a substring but I'm to confused how to set it can read every 2 word
I've got this problem where I'm supposed to be determining whether a string is a word or not. not exactly.Its supposed to just make sure each string has at least 1 vowel, and each vowel is surrounded by consonants. If it meets those requirements it'll be accepted, if not it'll be rejected, but I've already got that part figured out. I think I know a horrible way to do it, that would take a very long time, but I'm thinking there has to be a much easier way..

I am receiving data from other computer over tcp/ip and the received type is below...
"Info,Reply:Timestamp 75ff, SpecificID c07c343aInfo,Reply:Timestamp 76ff, SpecificID
c07c3089"
In the above string, i want to get only BOLD string value.
Sometime the data would be "Info,Reply:Timestamp 75ff, SpecificID c07c343a" and
sometimes it would be many repeated value like
"Info,Reply:Timestamp 75ff, SpecificID c07c343aInfo,Reply:Timestamp 76ff, SpecificID
c07c3089Info,Reply:Timestamp 75ff, SpecificID c07c345aInfo,Reply:Timestamp 76ff, SpecificID
c07c3088..."
Some people say I will be able to get them through regex.
But I don't know how to make regular expression for getting this value.

I am working on highlighting a word when entered in a textbox.
Example:
string = "hi this is <b>testing</b>"
When i enter the word "testing" in textbox and click on search then it is highlighting the word "testing". but when i enter "is testing" in textbox and click on search then it is not highlighting the word "is testing". this is due to there is bold tag for "testing".
How can we highlight the word which is in bold tag...
I have a string which contains words with parentheses. I need to remove the whole word from the string.
For example: for the input, "car wheels_(four) klaxon" the result should be, "car klaxon".
I'm currently trying to match a word in a string - to a word in an 1 dimensional arrray.
So it does this.
1.Goes into array, gets first word.
2.Looks for that word in the string.
3.If can't find it, go to next word in array.
4.And so forth until it finds it or runs out of words in array.
Problem is the string can be upto 2000 characters long. And the Array with the possible matches can have upto 8000 entries.
So when it runs, if the word begins with 'A' it finds it dead quick as the 'A's are at the top of the array, ordered alphabetically. This is great.
But if the word starts with 'Z' then it takes 4-5 seconds before finding it.
I'm basically using InStr to find the word in the string.

Is there any trick that could give me the first word of the str [code]...
