Write a function to print the Fibonacci value at a given position in the series.you should write two versions of the function both of wich must be named Fibonacci(overload functions).the first version should be implemented using a for loop.the second version should be implemented using do until.

View 2 Repliesis there a way that i can print selected objects only with their positions? I want to print only some pictures in their positions. Ive been trying to single them out but they end up in the top left corner of the paper.
View 1 RepliesHow do I get the current write-position using the BinaryWriter. I need to store the position in order to read from that position afterwards. (I know it would give the position where the next write would start, that will be taken care of).
View 2 RepliesI have 10 parts of a file. Each part is 10,000 bytes.Now say I receive these parts out of order meaning I cannot simply just write them in order as I receive them, but I am able to detect what part it is.
If I received part 3 how would I write those bytes in the 20,000-30,000 byte section of a file?
When i use this code my cursor goes to a point on my screen...Cursor.Position = Me.PointToScreen(New Point(285, 200))But when i use it a several times sometimes the position is slightly different...I can't figure it out why it is different after some time... Can i use the dispose function ?ps my form doesn't change in size and it doesn't move and always stays in the center of the screen.
View 1 Repliesi had generated some data in gridview and i had write it to a text file. I found that it is very difficult to align the data in a tabular form in text file. I had tried to put vbtab in the string and it appears perfectly in text file. However, when i wanted to print the text file, there are no spaces appear in the string. How can i make the write and print data in a tabular form perfectly in the text file perfectly?Anyone have any idea?

I was given an assignment to "write a program to print only even numbers between 6 and 16 using events", but I don't even know where to begin. The main thing I am having difficulty with understanding in this assignment is how I am supposed to specify that it only print even numbers in the given range of numbers.
Am I going to have to do a Mod2 code for each individual number and have it exclude any with the result of 1? Or is there another piece of code specifically designed for such an occassion? Perhaps there is some type of equation I can have the program read in terms of a variable, which holds the values of 6, 8, 10, 12, 14, and 16? I am just genuinely confused on how this is supposed to be programmed.
Ypos = TopMargin + Count * PrintFont.GetHeight(ev.Graphics)
ev.Graphics.DrawString(ROData(x, 3), PrintFont, Brushes.Black, LeftMargin, Ypos, New StringFormat())
Count = Count + CInt(ROData(x, 4))
The above line prints the data contents of the ROData array in position three. I would like to be able to assign a specific position accross the line to have the printer print the data at without left padding the array data.

I am trying to write a code for Fibonacci series in VB, but some of the values in my series are incorrect.Below is what I have so far.

I can get the results if I plug a number in for i, but I get them as a string for some reason.
Private Sub displayButton_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles displayButton.Click
'display Fibonacci results
Dim fib(10) As Integer
Dim i As Integer
Dim fibn As String
The assignment is this: User inputs the number of fib numbers they would like displayed. The program takes this number and produces that amount of fib numbers using a function and an array. Function can not display the results, that has to be done in the button's click sub.
Now, I really thought I had this array stuff nailed, I have done the random lottery number program and all that... but I think somewhere along the time it has taken me to get this messed up code I have written, it has also confused me to no end. I started off just being confused about how to display all of the variables in the array, now I am just not sure what is going on. I have successfully written this program without the use of an array prior to this.

View 1 RepliesI am supposed to design and develop a program to compute the first X integer numbers of the sequence, where the X value is entered in a numeric updown Control only using values 3-150. It is supposed to display the results in a listview control that has one column. I believe that I have the code correct but I am not sure how I am supposed to add items to the column in the ListView box. I have reviewed my text and there is information on creating the listview box and adding columns but it does not show an example on adding data to the column in the listview box. I can compile it with no errors but I can't debug it.

So I need to write a program that will approximate PHI (the golden ratio) using Fibonacci Numbers. It has to be within a negative power of 10 (between -1 and -16) oh PHI. So for example, if I put -2 into the input, the approximation of PHI would have to be with 10^-2 of the number that we're using of 1.618033988749895. Also, we need to show how many Fibonacci terms that were used to get to that number and the difference that the number that we approximated is to PHI.

How do I write the ln(x) function in general?

I have attached the form in initial state. What you don't see in the initial state is 10 hidden labels. I want the loop(which I am calling as a function??) to compute the numbers and display in the labels. Example, if I input 1 for the first term, 3 for the second term and 4 for the total terms, the first 4 labels should become visible and have in them one solution each:
1 - 1
2 - 3
3 - 4
4 - 7
