I'm a beginner and doing a review for my final...the question is-Write a Function procedure that takes an array of Strings, sorts it using Shell sort and returns the sorted array. I do not get shell sort at all.
View 3 RepliesI did this and no error or warning appears and when I run it only String[]Array appears in the listbox. can you help me fix this? I already have the logic down I am not sure how to fix this. My project is due tomorrow this is the only part I'm stuck on.

I am trying to code for is as follows: Construct a two dimensional array and enter into it a sales id number followed by twelve variables which represent sales totals made by the sales agent. this must provide space for five agents. I can declare the proper array and have done so as follows
Dim Sales (4,12) As Double. I also crafted a click event which will count from 1-12 (which excludes the sales id number) and disables the sales id number so it cannot get used. [Code]
What I am trying to do is setup a function within the same click event procedure which stores the current SalesAmount as a variable in the array and moves to the next slot to get ready to store the next SalesAmount. However I have no idea where to go from here. I have tried a ton of different pieces of code which are either all littered with errors or do not return a value when I call it. Calling the total of each row and the total for all rows is something I need to do for display and I am not one hundred percent sure I know how to do that either.

To have a function that takes the average (which is calculated by a different function) say for example the average is 6, now the function is to take the number 6 and get the variance from six to another number lets say its 12 so this will return a calculation of 50% variance. now here comes the issue, i have it calculating the variance how ever lets say that there is a score that is 0, how can i make it calculate the variance without taking count for that 0? i guess you can say i need it to "skip" if its a 0.

Alright, So ive returned to using vb after several years now. Ive programed in VB6.0 years ago and I was quite proficient at it. However after returning to vb (now using Visual Studio 2010). Either Ive forgotten everything, or something has changed. For a university project. Im trying to write a program that takes a string of bits and encrypts it using DES Encryption.

I have a function that takes a String as a parameter And in it I have variables, so if I call it it's like
Dim Text As String = MyStringConverter("Hello Mr. " & Name & " " & Surname "!")
Is there a way in vb.net to create a sub/function that will take as an argument some kind of pointer to another function, and allow this new sub/function to execute the passed function? What I have are 10-12 xml-rpc functions I am calling against a remote server. Each of these functions has different argument lists (one takes 1 string, another might take 3 strings and one int, etc). All of them return an object.

I'm migrating from VB6 to VB.NET, in hence my questions below:
I have to write a function that returns array of strings.
How can I initiate it to empty array? I need it since I have to check if it's empty array after it returns from this function.
Is list of arrays better for this purpose? If I use a list - Is it empty when it firstly defined? How can I check it it's empty?
what exactly is the type of the second argument of CType
CType(testobject, Control)
what exactly is Control? how can Control be used as though it is an expression?i nid to know this because i'm trying to build a function that takes the exact parameters of CType, let's call it CType2public function CType2 (byref object as Object, byval thetype as Type) as Object problem is when i do this: CType2(testobject, Control) they give me "Control is a type and cannot be used as an expression".
I'm currently invoking a function that takes ByRef parameters using Control.Invoke (which I notice specifies the Object parameter array to be ByVal) but the array of parameters I give it isn't updated by the function. Is this possible with VB.Net 2003 or must there be some error in my code?
View 5 RepliesThis is probably a stupid question, but how do you make a function which takes a number then does an operation to it again and again until it gets a vlue which it already has seen, when it returns all of its values? I have this function:
Private Function fractal(d as string) As double
Fractal = Val(D) * (Val(D) - 1)
Fractal = FormatNumber (Fractal, 2)

I need to write a program in VB 2008 express that takes an user entry from a textbox and strips out all the spaces, changes it to either all upper case or all lower case then checks to see if it is a palindrome. I must also include a loop structure and a decision structure. I have seen bits and pieces of code but I do not really know how to put them together. Basically I need it from the button click to the end. ?
View 3 RepliesI've been looking at threading to make my webapplications more responsive. I've found out how to thread a sub that takes no variables and doesn't return anything, but I can't find out how to achieve this for a function that takes variables and returns something. here is an example
[Code]...
Dim str As String
Dim str2 As Array
str = "blabla duhduh"
str2 = str.Split(" ")
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..
