How To Write A Procedure
May 3, 2011
Write a Visual Basic Console Application. Inside the main procedure call a function procedure to input and return a value for a double variable called x, the width of a right triangle. Inside the main procedure call the same function procedure a second time to get a value for a double variable called y, the height of a right triangle. From the main procedure call a function procedure which calculates and returns a value for the "hypotenuse" equal to the square root of (x squared + y squared). You will have to pass the values of x and y to this function procedure. The procedure should calculate and return a double type value. The value that is returned by this function procedure should be equal to the square root of (x squared + y squared). Also from the main procedure call a sub procedure to display the values of x, y, and the hypotenuse.
This is what I have so far..
Option Strict On
Option Explicit Off

i created a list of picturebox arrays in my program :
Dim MyPicArray As New List(Of PictureBox)
and i used this code to add them:
MyPicArray.Add(New PictureBox())
[Code].....
the above code works the pictures are created in the form but now i want to write events for them, for example in the 'Click' event a messagebox shows. i don't know how to write the procedure i have tried this but it didn't worked :
Private Sub MyPicArray_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyPicArray.Click
MessageBox.Show("It Works!")
End Sub

I am trying to write a protection procedure, which will allow me to create a licence key for our users. This licence key will ensure that the software can only run on the registered system, and will allow the user to access only specific areas of my program which is relevant to them.
I am thinking of using an RSA style approach to this where I want to be the only person who can create the registration keys. But I want to allow the program to be be able to decrypt the key. This is to prevent the average user from being able alter the key and remove any restrictions which are being imposed on the program by the license key.
The process that this would take is to produce a host id which has went through a series of tasks to distort the actual value from the user will return this code us, and from this host id I can then work out the original value of the code. Using these public and private keys I can then encrypt license key information.
However I would like to know how I would implement the private key encryption and key generation program in .NET, so that I can get this setup working in a manner which will allow me to generate keys and allow the program to decrypt keys.

In a tic tac toe game I am making there are two blocks of code that are identical except that they access different arrays:[code]Arrays plyrTaken and plyrPairs are used in the first block and cmptrTaken and cmptrPairs are used in the second. Is it possible to wrap these blocks into one Sub Procedure passing the different arrays when the procedure is called?

I finished coding an application for converting Celsius to Fahrenheit, and vice versa. I used the Sub Procedure to convert them. What I need now is to modify it. I would have to use the Function Procedure instead of my Sub Procedure.

I have a stored procedure to update a table, but needs a couple of values from another table.
the first two selects get the value from the table and then are used in the update statement.
The select statments:
Select @iStatusDropDownValueID = iDropDownValueID
From DropDownValue
Inner Join DropDownValueType On DropDownValue.iDropDownValueTypeID =
[Code].....
First, the values that are retrieved by the first two select statements are always the same. So they could be passed in by the code itself. I don't know that this will speed things up at all, just make the entire stored procedure better and easier to read.
Second, if the "Value Name" should change this store procedure will break (which is possible, but not often).
I am looking for any insight into the Best Practices for this situation.

OK. So I have a class-level array:
Dim terrain()() As Double and I want to add the bounds in a procedure:
Dim terrain()() As Double = New Double(divisions + 1)() {}I can't add the bound for the seconds dimension.
Then I want to assign a value to any element of the array inside the procedure.
terrain(0)(0) = 0.5 This gives the error: Object reference not set to an instance of an object You can see my problem. What solution can there be to this problem that involves one array.

I have noticed the following but unable to understand why.Whenever a procedure is called in .net it takes more time than when it is called subsequently.Even if a procedure is called after some interval it takes more time than it takes if it is called quite frequently. i am not asking about sql query or sql command. any user definded function or user defined method takes much more time to finish when it is called occasionaly. but when the same procedure is called quite often it finishes a lot faster. why?

I have been creating a little utility to generate random alpha-numeric username and password combos so I don't have to input this stuff by hand. A time saver. Whenever I clickbtnGenerate it generates a new set of random numbers, adds them where directed but only generates one ne set per click. I can't seem to figure out how to get it to loop the number of times I have typed into txttotal. So, if for example I needed 1000 uniqueusernames/passwords I'd like to, in the runtime, input "1000" into

I am currently building an ASPX webpage for internal use. Basically, there are two buttons on this page and I need each one to kick off a different stored procedure on our local SQLServer based on the needed task. these stored rocedures do quite a bit of work and take 3-5 minutes to finish running. In neither case do I need any kind of gridview or other output from these stored procedures, as they are simply crunching/cleaning data that will populate some tables that the user will then use to complete their task. There are also no inputs or parameters needed.
So i'm OK at ASPX and pretty good at SQL, but have no idea on the VB code behind page. This is what I have ben able to put together based on 3 days of googling. i think i am close but can't quite get across the line.
CODE:
I'm not sure if you need to see any of my ASPX or my SQL. both work fine on their own, but i am not able to get these buttons to work.
