I know how to cut off characters at the end of a string using vb script, which uses the LEFT(string, #) syntax, however, how do i do this using vb.net?
and my second question, I have a string being sent into a drop down menu that gets the data pulled from an access database using a data source control. How do I format it so say, it only shows the first 100 characters of that string in the dropdown?
I'm new to Visual Basic, and I'm trying to figure out how to make a drop down menu to select the font in a text editor, like Microsoft Word. Does anyone know how I could do that? I'm using Visual Basic 2008 Express Edition.

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.
How do I trim a text if text's width is bigger than a specific unit of measure (for example 3 centimeter).
View 14 RepliesI 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.

View 2 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?

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 1 RepliesSo basically im around 2 months into building a text based rpg game in vb 2010 which is coming along lovely. there are unique charachter creations, bans, loans, monsters to fight, levels, skill points, spells, inn's, etc etc... you get the idea. so now its time to move on to one of the largest problems of all. an inventory :O now, i have a db with the correct information in, i have even sorted all the code for the program to read the db with the correct items and its all working fine. but now i would like to have a more gui system. meaning:a grid based box where pictures of each Item_ID are displayed so you can see what items are in your inventory at any time. now i can sort this out myself with a case select and just load all the images into the local resource and pull itempictue1 when id = 1 itempicture2 when id=2 etc etc you get the idea. what i was woundering is...
could i build a drag and drop system where the player can move the items inside the inventory fairly easily? i have done some research into this but as vb isnt much of a gaming language i've run into a fair few dead ends. Not sure if i have come across right, but in essence, if you have a grid, 4x4 and item 1 is in grid space 1 and item 2 is in grid space 2.. to swap them around with the mouse.Please, dont shout if im asking too much :L nobody likes haters. any help is much appreciated and if you dont think vb can do this then please tell me and i will consider all alternate possibilities unless you have a better idea?
I'm having trouble on how to code this. First I need to assign a value for every item in the list (1 for the first item, 2 for the 2nd and so on). Does this control have a separate field for the value aside from text?
Second, I need to insert this into my database(MSSQL 2008) in this format:
insert into table values(ID,selectedvaluegoeshere)
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'm trying to automate a form process from a previous employee. One of the things that I have to do to achieve this is select a COM port from a dynamically populated list. I've looked around and the closest thing I could come up with is something like:

True
While this compiles, the computer does not like this at run-time. It throws an exception out:
"Object variable or With block variable not set."
