I'm creating a text box with auto-suggested. So, it works well. It suggests only first name, but I want it to suggest the full name (first and last name which two different columns). Take a look at the following code behind that worked as expected :

I figure I should use 'Aggregate' but apparently I am getting it wrong First I get a list of my Entity objects Dim employers As List(Of myEntity) = (New XXXX()).getZZZ(userName, userType) Then I figured this would be a way to put all the names in a string Dim names as String = employers.Aggregate(Function(current, [next]) current.Name & " " & [next].Name)

I have a concatenated string like...
str= 1010,5050,6079
And want to separate the string In Javascript I can do
string = Srt.split(","):
and the result...
string[2]=5050
Is there a way to do this in VB.NET?
I'm suppose to end up with a label box with my name spelled out in it using string manipulation. This is suppose to happen using the concatenated string to output the name into the label box. I don't have any error codes but I also don't have my name in the label either. [code] "Lorem Ipsum is simply dummy text of the printing and typesetting industry. Lorem Ipsum has been the industry's standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make a type specimen book. It has survived not only five centuries, but also the leap into electronic typesetting, remaining essentially unchanged. It was popularised in the 1960s with the release of Letraset sheets containing Lorem Ipsum passages, and more recently with desktop publishing software like Aldus PageMaker including versions of Lorem Ipsum.It is a long established fact that a reader will be distracted by the readable content of a page when looking at its layout. The point of using Lorem Ipsum is that it has a more-or-less normal distribution of letters, as opposed to using 'Content here, content here', making it look like readable English. Many desktop publishing packages and web page editors now use Lorem Ipsum as their default model text, and a search for 'lorem ipsum' will uncover many web sites still in their infancy. [code]

I am writing a tool that logs stats for a first person shooter game. The game writes its information (including who killed who with which weapon) to a log file, which I read every so many seconds and parse so that I can write that information to a database.I am now having trouble parsing the weapon out of that string of information.
Some additional information is required: a weapon in this game can contain attachments (such as a scope, a grenade launcher, etc). Weapons can have either 1 or 2 attachments. Some weapons however cannot have any attachments at all.
Each log file entry that describes a kill contains a code that describes the weapon that was used. This code is a concatenation of either 3 or 4 parts:
<weapon>_<attachment>_mp
<weapon>_<attachment1>_<attachment2>_mp
where <weapon> is a code that describes a weapon and <attachment> is another code describing the attachment.This should be easy to parse by just splitting along the underscore characters, but there's a few catches:
1. Some attachments are able to kill players as well. Specifically: grenade launchers, flame throwers and underbarrel shotguns. In this case, the attachment is listed before the weapon:
<attachment>_<weapon>_mp Note also that in this case there is always only 1 attachment.
2. The biggest catch: some weapon names have an underscore in them (some even have 3 underscores)! So simply splitting along the underscore won't work in all cases; if the weapon name contains an underscore I'm splitting the name of the weapon..This makes the list of possible combinations a lot longer. The ones I can think of (I think these are all):

I am trying to programatically create textboxes in my app. I need to do this:
dim textbox(x) as new textbox
x needs to loop 1 thru 10 but I can't get VB to accept my coding.
I have a dictionary that I want to access with a key that is the combination of a string (AcctNum) and a date (BalDate).It seems to me the simplest approach is to create the key by simply converting the date to a string and concatenating:MyKey = BalDate.ToString & "|" & AcctNum
I know I also have the option of creating a composite key by writing a separate class and overriding GetHashCode() and Equals() a la this solution. To me, the concatenated string is a simpler, if somewhat less elegant, solution. Am I missing some compelling reason why I should go with the composite key class approach?
This lookup is the crux of the project I am working on, so performance is my main objective (with readability a close second).
I need to sort the values of my listbox to have the latest date on top plus some text. here is the code I'm using:

View 5 RepliesIve created a few in-house applications using Access, such as an IT Ticket tracking database and a database to store legal case logs, but finally found a project that I knew would completely out-grow Access and Im trying to incorporate my previous knowledge in to Visual Basic/Visual Studio.That being said, do any of you have any suggestions for intermediate-level reading material or tutorials, especially on how SQL Server and Visual Studio mix together? I've picked up a copy of Sams Teach Yourself Visual Basic 2005 in 24 Hours, which isn't too bad but I've had to skip around quite a bit because I'm already pretty familiar with the interface, I just need some more assistance with the code. I've also purchased Murach's Visual Basic 2008, but I haven't cracked that one open yet.At any rate, I look forward to talking with you all.
View 1 RepliesThis feels like a completely basic question, but, for the life of me, I can't seem to work out an elegant solution.
Basically, I am doing a LINQ query creating a new object from the query. In the new object, I want to generate a auto-incremented number to allow me to keep a selection order for later use (named Iter in my example).
Here is my current solution that does what I need:
Dim query2 = From x As DictionaryEntry In MasterCalendarInstance _
Order By x.Key _
Select New With {.CalendarId = x.Key, .Iter = 0}
[Code]....
Is there a way to do this within the context of the LINQ query (so that I don't have to loop the collection after the query)?
I'm working on building an HTTPHandler that will serve up plain text for use with jQuery Autocomplete. I have it working now except for when I insert the first bit of text it does not take me to the right portion of the alphabet.[code]...
My question is, how would I implement this concept into my HTTPHandler without doing a fresh SQLQuery on every character change? IE: I do the SQL Query on the QueryString("ID"), and then on every subsequent load of the same ID, we just filter down the "Part".[url]...
just want to know if linq to sql auto updated the id column of a class (table row object) after SubmitChanges is called inserting a new row to that table, that would be fantastic, would anyone be able to confirm this?

I have a project which has a table with a list of stores. Originally the store code was a string of 3 and was padded so 1 would be 001 etc. I have had to increase this column to 8. The problem is when I read in data from a XML file the store code is padded so it looks like this '500 ' rather than '500'. This is now causing a major problem when I do a comparison.Is there a way to it does not auto pad to the full string length?

The format we need is "dd/MM/yyyy" The dates are messy such as "dd-MM-yyyy" or "dd.MM.yyyy" so I am thinking to write a function that will auto correct on a set of predefined separators to a correct format. so I am thinking to do something like this but of course, this won't just work.i cannot use replace to replace an array. If i can just do that, everything would be fine. Hope someone can point out a way around. [code]
