Output Name Using String Manipulation / Concatenated

Aug 15, 2011

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]

For my application, there is a login form in which users have the option for it to "save the login information" Kind of like MSN or other websites in which you go to a login page an the information is filled out. On my login form, I am using this code for my checkbox which is to "save login info"

VS 2010 Parsing Concatenated String?

Jun 25, 2011

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):

.net - Dictionary Access: Composite Key Vs Concatenated String Index?

Jan 31, 2012

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).

Basically I have a webresponse stream:dim lol as string = readstream.tostring there is a lot of information within the string but only one link starting with http: located near the end of the string - however there is no constant character point where I can start... (i.e. 38)

I want to extract the link from the string i.e. dog cat plane car [URL]..that is approximately how it looks above - words and url substituted I want to just extract [URL]..I had an idea of parsing the string from http: to the end Then after that splitting the string up again to remove the }], however it does not return anything

Asp.net - Decimal.parse Fails For Currency String Created With String.Format?

I verified that the value in amount.Text is "$28.28". Am I missing something? Shouldn't these two operations use the same currency symbol and formats?
