Can't Seem To Use String.Trim()

Jul 12, 2010

I'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.

Compare A String And Trim?

Apr 9, 2010

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.

Gateway Address - Trim String To Certain Character

Jul 17, 2011

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?

Textbox - Trim Value Of String To MaxLength Characters Automatically?

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.

VS 2010 Doesn't Trim Get Rid Of Null Bytes In String?

Jun 17, 2010

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:

Regex / Check For Preceding And Following Character

Jun 10, 2011

Sometimes when backing up an sql file using phpmyadmin (database stuff), for some reason it forgets to double up a single quote, resulting in an error when loading the sql file back into the database when required. A line in such an sql file looks like this;[code]As shown in the example, phpmyadmin did double up the quote in "you're" as it should, but it forgot to double up the one after "27", resulting in an error.As you can see it's like this (*value*, *'value'*, (and so on) but beforehand I can;

A) Never know how many values are in such a string
B) Can't simply split the values by "," because the value itself can hold a comma aswel.

It would be easy if every value was like this; *'value'* because then I could split by " ', ' " but that's not the case, and I also never know what location the values not enclosed in single quotes are. I also can't simply double up all single quotes in the entire string because then it will also double up the ones that are enclosing the values, resulting in an error during upload again.So yeah, what I need to get done is single out all the values with regex ($1, $2 etc.) and then string.replace single quotes in those values but *only* if said single quote is not preceeded or followed by another single quote, else it would become a tripple quote resulting in an error again.

VS 2008 Different Ways To Call Another Form From A Parent Or Preceding Form

Aug 4, 2009

I need to know the proper way, or maybe I should say, the different ways to call another form from a parent or preceding form. I am currently using ex: formname.showdialog() to call my next form, but I am uncertain if I should be using that in every situation. [code] Whats the difference between these different methods? (ex: .showdialog() , .show() )I tried both of these to open a temporary form to retrieve a persons name from a database, so as the users progresses through my training program they can keep track of their scores.But, I also call other forms as I branch through my program, from the main page, to a secondary page, to a testing page, to a results page and then back to the secondary page

'TRIM' And 'DATABASECREATIONSCRIPTS' Error

TRIM IS NOT A MEMBER OF SYSTEM.NET.MAILADDRESS

and

DATABASECREATIONSCRIPTS IS NOT A MEMBER OF RESOURCES

What I cannot understand is why these errors are appearing as this program has been published before (not by myself) and is working correctly.All I have changed is the IP address which the program connects to in several different places. No hardcoding has been changed.

Performance - Trim A Log File With .net?

Oct 29, 2010

I'm writing a simple application in vb.net and need to output some information to a log file for diagnostic purposes.In order to ensure that the log file doesn't get too big, I need to trim it to a certain number of lines (say 5000). For performance reasons, the trimming doesn't have to occur each time a log entry is written out nor is it critical that trimming occurs (for example, if the application crashes prematurely).

However I'm not really sure the best way to trim it. Loading the entire log into memory and then re-writing only the last 5000 lines back out would work, but I'm sure there is a cleaner and better way to do this.
