How do you get the absolute value of a number in vb.net?
Is there a function built in? I know I can simply code a function myself, but I want to know if there is one already there first. It seems so simple, I could probably make it in three lines, so I would be surprised if there isnt one....
I'm trying to determine in vb if a URL is absolute or relative. I'm sure there has to be some library that can do this but I'm not sure which. Basically I need to be able to analyze a string such as 'relative/path' and
View 3 RepliesI am trying to convert a web application from using hard-coded deployment locations (ie, /base/path/index.aspx) to discovering them at runtime. If I use Response.Redirect(), I can express the path as '~/index.aspx' and, at runtime, ASP.NET will build the correct URL to send the redirect to based on where the web application is deployed.
There are places in the code where Javascript and/or HTML is generated dynamically and sent to the client as part of the response to force a new window. In these cases, I don't know how to get the actual URL that should be opened in the new window. Using ~ doesn't work in this case since the URL is being evaluated by the browser and not the server. Is there a class or method in ASP.NET that will give me the URL I am looking for? I'd look myself, but I don't even know how to properly phrase my question.

View 2 RepliesWhen I'm coding in Visual Studio 2010, say that I have some interface:

It does the same thing for all methods, etc. that I have to implement and it's mildly annoying to either have to look at a stupidly long reference, or clean it all up since I'm importing the namespace at the top of my class anyway. Is there a setting in Visual Studio that I can use to switch that?

I have a problem with a sql query. Through the query I am trying to search database for any occurrences of string (can be anything) in a column using the SQL LIKE command. The problem is that it works fine for most of the strings say john, jim, ji"m , but does not work when i include the following characters which are ( ' , { , } , and a single quotation mark). MYSQL query takes care of these special cases by putting them in [] block whenever user enters them .But i am getting the following error when i go to query the database using the GetSelectCommand() in VB.NET
Exception Details: System.ApplicationException: Number of values provided must be equal to the number of placeholders in query.I have checked the query over and over again .. but its fine .My database server is Sql Server 2008.So my application throws the exception in this command:

I am attempting to create a game in Visual Studio 2008 that allows a user 10 attempts to guess a random number between 1 and 50. I have a label box in which I would like to display the remaining guesses as they decrement. The code so far appears below.
My two (I am sure very basic) questions are:
1. How would I pass the random integer generated through the Generate Integer function to the AmIRight button's click function? I was trying to decrement the counter each time the "Am I Right " button is pressed.
2. I would also like to evaluate each "guess" when the "Am I right button is pressed. Is it possible to nest a Select Case statement in a For Next Loop?

i wanted to create a random number generator that iterates through a series of number between an upper and lower bound. say between 1 and 100. Basically I want the number generator to pick the numbers randomly and then display them until all 100 numbers are picked without any duplicates. so thats easy I can code that. But what I don't know is how to show those numbers in the order they are generated on a windows form. So i have basically a variable that I will let be changed 100 times (or however many times I want, I don't want their to be a size constraint just using 100 as an example) and each time the number is generated I want it displayed on screen (in a list or something not sure what. Hopefully some type of scrollable list) and each successive number also to be displayed in same format beneath it so that I can see the list in its entirety. What type of form control do i use for that? I could do messagebox.show for each iteration but then user is required to hit ok after each iteration and that would obviously be a bad idea if user selected a large number to work through. Anyways, code isn't exactly necessary just point me in the right direction, i.e.what control (if any) to use.how to format the change in data?

I am trying to make a basic ATM system, iv got all the interface done and I have made the link to my SQL database etc. the part i'm stuck on is how I can run a check to see if a bank card number matches up to the users PIN number. To simulate the user putting a card into the machine I've used a combo box, and that lists all the cards, that haven't been flagged as confiscated (there's a column in my ATMCards table that I can set to true or false) then after the user has selected a relevant card there's another text box where they can enter in their PIN number.
Now what I want to do is, if they chose the card number 1234567890123456 in the combo box and they enter in the PIN 1234 into the text box, then, after clicking the check PIN Button if the pin is correct they need to be taken to another from where they can check their balance etc., and if its wrong they got three attempts after which point i want to flag that card as confiscated.
