View 3 RepliesI'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?

for example, If I had the following string: Dim str As String = "Hello World"

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 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.

I am trying to strip the first 75 characters from various strings (sentences / phrases) and it seems right but I need to ensure that the no words are truncated in the process. Meaning that if the 75 character is part of a word it needs to fall back to the beginning of the word or nearest space..
I thought of stripping the entire string into separate words and then counting the length of combining the words and stopping when I reach the target but what do I do in the case when it is not a valid sentence just a bunch of characters jammed together or spaces and one character. I thought of using grammar parsing tool libraries and parsing into tokens etc but that seems too over complicated.
Here is what I have so far:
If htext.Length() > 75 Then
Dim regex2 As Regex = New Regex("^.{0,75}", RegexOptions.IgnoreCase)
Dim m2 As Match = regex2.Match(htext)

View 3 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.

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 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.
I'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:
