Write a program that requests a name fomr the user and insert the name into the list in its proper location, if the name is already in the list, the name should not be inserted. --do not use any arrays or LINQ use only streamreader/streamwriter.What i've got is this...it will add the name but not in the "proper location". if i could use an array i'd just reorder the array and then write to file, but...

(Write a program that requests a word containing the two letters r and n as input and determines which of the two letters appears first. If the word does not contain both of the letters, the program should so advise the user.)I got the program to work but he said its wrong because we need to have it looping and if one of the letters is missing you also have to say which one is missing.I have some of the pseudo code but I don't know how to make it work.If Index of("R") = 0 or index of ("N") = 0 Find out which is missing and display message.Else Find larger and display message.

Is it possible to make a program intercept and stop certain write requests? I need it to stop viruses from tampering with an antivirus database. If you can, how do you do it? If not, is there another way to stop viruses from changing the database?

I need to write a program that requests a high number and a low number from the user, then the program searches the array and finds all elements within the two numbers. The program is used to search for past presidents, so if I type 43 for low number and 44 for high number, the program will display:
George Walker Bush
Barack Hussein Obama
I think I have an idea of how to search up to a certain point, but not to stop at a certain point....Here is the code that I have for that particular sub procedure:
Quote:
Private Sub btnDisplayRqst_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnDisplayRqst.Click
Dim sr As IO.StreamReader = IO.File.OpenText("PRESIDENTS.TXT")

I am trying to make a html editor that allows you to preview the code as you type.
The users are able to see a live preview of the text they're typing. What I'm trying to do is get the webbrowser to load images from a different location. So, when the user changes the text in the richtextbox, the webbrowser.documenttext is changed to the text of the richtextbox and the page is loaded. But, if the code contains images, the webbrowser won't load them because there isn't any file, just the documenttext. The richtextbox is linked with the actual file itself, but I can't make it constantly write text to the actual file because that would make the save function pointless. Writing the text to another file in the same location isn't an option either, because that is too slow.
So, how can I make the webbrowser read the images from a self-selected directory?

My question: Where is the proper place to embed the IV info?
My initial thought is to append it at the end of the file's content. Is that a good choice?

I am trying to write a program that allows user input information and plot a bifurcation diagram that looks like this:I haven't program in 2 years:sick: so I am all rusty and such. Here is what I have got so far and more information about what I am doing.
Bifurcation:
f(x) = kx(1-x)
and k = xL + i * (xR-xL) / 500
when i runs from 0 to 500, it plots (i, f(seed)), (i, f(f(seed)), .... up to the boundary number.Here is what I have got so far. Everything seems normal, however, I am really confused when it comes to plotting.

Its then supposed to go to a 2nd form when you click show score, grade it, and display whether each answer was right or wrong. I'm missing something easy probably.

I'm wanting to write a program where a user can copy text from a pdf file, paste it into my program and it can identify which file the text came from and where in the file the text was copied from. This is so that later on, the user can then select the pasted text, and the program can load up the source pdf and highlight the text section.Are there any components out there which I can use to accomplish this

I have to write a program that will allow a usert o track the invitation list for a party. The user can enter the name of a person to be invited. When the send Invitatin button is clicked, the name appears in the checked listbox. This counts as an invited person.When an invited person confirms that they will be attending, the user will check the name in the checked listbox. this counts as a confirmed person.
What I am having a hard time figuring out is the codes! What would I declare my integer variables to hold the count of invited persons and the count of confirmed persons? And how would I code a loop to check if the name enetered in the name textbox already appears in the list box, if so, display a message telling the user that this person has already been invited?

i did this much but something doesn't seem right...the question is A Visual Basic program that requests a positive integer as input, and carries out the following steps:If the number is even, divide it by 2.Otherwise, multiply the number by 3, and add 1 to the result. Repeat this process with the resulting number, and continue repeating until the number 1 is reached.After the number 1 is reached, displayed how many iterations were required to reach the number 1. (Hint: a number is even if number Mod 2 = 0.)

I'm currently in VB class at my highschool and we just got chapter 6.1 to read on this online textbook that we follow. Anyway, we are doing loops now and the problem reads "Write a program to request positive numbers one at a time from the user in an input dialog box. The user should be instructed to enter -1 after all the positive numbers have been supplied. At that time, the program should display the sum of the numbers." So far I know this much
[Code]...
Now I know this isn't right But I can't find out how I'd pull out the numbers the user entered to get the sum of them and not include -1 because as it stands, when I hit ENTER with -1 the label just shows -1.

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. ?

I have a dynamic webpage that loads a user control multiple times, including loading the user control within itself as many times as needed. Within the user control there are four controls: Title Label, Repeater, Placeholder and within Repeater a AjaxControlToolkit Rating control.
The structure can look like the following:
Webpage
Placeholder
UserControl (repeater hidden, no data)
Placeholder - [UserControl]
[code]....
how do I efficiently loop through this type of structure to find the rating controls?

I have a db, and one of the columns in my db is an attachment column. It stores the link to a pdf document. I want the user to be able to browse through folders and select the proper pdf file. And when the user finally hits the submit button on the form my algorithm should put the necessary link into my db. I'm just not sure how to do this with regard to VB searching and finding the file, and then using my SQL statement to insert the attachment into my db.
Here is my code so far.

I am creating a program that allows a user to view a list of foods in a combo box, add that food unto a list box, and adds all of the calories of that food together. When the user highlights their select food, the program automatically shows the amount of calories for that particular food in a text box. The program is getting the food and calorie information from an access database. I managed to get all of the food calories to add up properly, however, I ran into a problem. Sometimes, well, most of the time, when I select certain foods from the combo box, the program automatically reselects another random food, usually a food that begins with either an A, B, or C. Also, the other random food that the program chooses usually has the same amount of calories as the food I originally wanted to choose. I have over 6,000 items in the database. I don't understand why this is happening. This is what my code looks like for the button that adds each food to the list box:
Private Sub Button4_Click(sender As System.Object, e As System.EventArgs) Handles Button4.Click
Foods_Selected.Items.Add(ComboBox1.Text)
Static i As Single
[CODE]...
And this is what my code looks like for the button that adds all of the foods together:
Private Sub Button1_Click(sender As System.Object, e As System.EventArgs) Handles Button1.Click
Dim x As Single
Dim TotalCalories As Single
[CODE]...
I have no idea what to try. It's like the program just skips over random foods, even though all of the information for them is in the database.
