VS 2010 Storing Information As A String Within An Array?
Jan 23, 2012
I'll try to explain what i'm doing here, i wan't look through a text file, adding certain lines to an individual array element. So i want to build an array with mcode, mTitle, mCredits, mSemester, moduleStats, currentYear <--- this information as an array element. So here is my attempt at the code,
Dim sr As StreamReader = New StreamReader("datasource.txt")
Dim line = sr.ReadLine() ' get each line and store it
Dim currentYear As Integer

I have a list of names in a database and what i want is to get all of these names and display them in a label or a text box to the user on the website. I have tried to do this using a for loop but it is always overwriting the label each time. I have a list of 10 different names in the database and what it is doing is putting the first name in the label and then overwriting this with the second name and so on until it reaches the last name. I think i need to store each of the names from the database into an array or an arrayList and then make the label display all of the contents from the array or arrayList. The for loop i have used for this is:
Dim g As SQLadmin = New SQLadmin()
g.DB("SELECT nameOfPerson FROM Persons")
For i As Integer = 0 To g.array.GetLength(0) - 1
[code]....
i can select the names from the database and store them in an array then make the label display each of the names.

I have a done the following steps:
1. I took a decimal point number, suppose 192.123456
2. Then removed the decimal point
3. Concatenated the L.H.S and R.H.S and stored it in a string
4. The string that I got was 192132456
Problem: Now I want that the I should be able to reverse the string such that the string should become 5624132901. I have tried using the arrays but it gives me an error when I try storing a string into an array. I am pasting the code below:
NOTE: Code does not contain the implementation of arrays as discussed above. The logic below is without arrays.
Dim maindecimal_R_Reverse_Parts As String = ""
Dim mainbandnumber_R = CStr(MainBandText.Text)

Recently I started a project with the goal being to have text that was inputted into a textbox stored within a three dimensional jagged array. The idea is that every time a button is pressed, whatever text that is inputted into the textbox is split into separate elements, where each word occupies its own element in the array. So for example, if a poem were entered into the textbox and the button clicked, each word of the poem would be assigned to a discrete element in the vertical dimension, and each line of the poem assigned an element in the horizontal dimension. After the text is stored into the 3D jagged array, the text should be cleared from the textbox and a counter should then ensure that on the next button press, the new text inputted into the textbox is stored in a discrete element of the array. Below is the code I have written so far, but I know that I am far from having anything might accomplish what I have just described.

I'm obtaining data from a StreamReader.My StreamReader is called "reader" and I'm reading the stream with "responseOutput" like this "responseOutput = reader.ReadToEnd()" And in that bunch of text that I receive I want to FIND and EXTRACT a piece of text and then STORE that extraction in a variable of String type.Here is part of the code I'm referring to:
Dim response = request.GetResponse
Dim responseOutput As String
Dim reader As StreamReader
reader = New StreamReader(response.GetResponseStream())
responseOutput = reader.ReadToEnd()
And here is the text or data that I'm receiving (what I'm about to show you is the result of a "MessageBox.Show(responseOutput)":
<TweetPhotoResponse xmlns="http://tweetphotoapi.com" xmlns:i="http://www.w3.org/2001/XMLSchema-instance"><Large>http://cdn.cloudfiles.mosso.com/c54092/x2_7e143b</Large><MediaId>7e143b</MediaId><MediaUrl>http://tweetphoto.com/8262715</MediaUrl><Medium>http://cdn.cloudfiles.mosso.com/c54102/x2_7e143b</Medium><Original>http://cdn.cloudfiles.mosso.com/c61132/x2_7e143b</Original><PhotoId>8262715</PhotoId><SessionKeyResponse/><Status>OK</Status><Thumbnail>http://cdn.cloudfiles.mosso.com/c54112/x2_7e143b</Thumbnail><UserId>2268670</UserId></TweetPhotoResponse>
And all I want to do, is to extract a specific part of that text, which is the "PhotoId" value (I highlighted it in red), in this case the value is "8262715", and then store it in a variable (I know how to do that I just need the value).The text or data I'm receiving changes only the PhotoId everytime it's requested.

"I need to create a program that will allow the user to enter in 10 test grades from a class. I need to store these grades into an array, and use a loop to add up the total. Then I'll need to output the average, and the letter grade for the average using:

im writing a program for my vegetarian girlfriend that does two things from the main menu. 1: add foods with attributes like name, iron content, protein, sodium etc. 2: use the foods that have already been stored and use them to make a balanced meal. What im having trouble with is, how do i save the attributes when storing the foods ? i have knowledge with c++ so i understand how classes work and was wondering if there is something similar in Visual Basic.

I am creating a program with multiple Forms designed to track multiple projects.The first form is designed to setup new projects and obtain previous projects, from there the other forms open to be filled in with information.For new projects the next forms open blank but I then need these later forms to be tied to this project name so that it can be selected from a combobox and the information will be already populated.tieing the information on the later forms to the projects populated in the combobox so that it appears when a specific project is selected.Is this able to be done without creating databases?
As an example, say I create a new project then a new form opens and I add some information to a textbox.I would then like to be able to save the information so that the project name moves to the combobox on the first form (I can handle this) and the information input in to the textbox is tied to the project name so that when the program is reopened and the project name is selected the second form opens with the textbox populated.

I am making a program that stores information for my applications. There are 4 main things I need in the XML file, the login information (User name and password), Application names and keys, and the owner of the application (who bought it). The program allows the user to enter as many applications and owners as they want and once login information is correct it loads the data. Then on exit all the data saves to a XML file.
My XML file looks like this
<Data>
<Login>
<UserName> (UserName) </UserName>
<Password> (Password </Password>
</Login>
<Applications>

I need to construct a small program that "stores" entered test scores into the program then when a button is clicked, it will display the scores with the appropriate names in the box below. The values are the names "Brian" "james" "jimmy" "jock" and "gok" and there are two test scores "main test" "small test".. I need to be able to "store" these in a "database" and then when the user clicks "show marks" it displays all the names with the marks in a table format. I'm totally screwed and i dont know where to start..I already have done a little coding for the gui such as a password entering system and all that works, all I need now is this storing thing.

I have a whole bunch of information that has been parsed from a web page and i want to insert the data into a multi-demensional array and the compare the data of a certain array element to another array in the same format to determine which is missing/added.So if i have this:
Type of animal | Color | Age
Cat, Brown, 15
Dog, Pink, 6
Fish, Orange, 4
[code].....
I only want to compare the type of the animal and the color and age is irrelevant.I want it to let me know whats missing and what's been added.Sounds bizarre but yeah. It doesn't need to be arrays, it's the only thing i know of though.

note, this is homework. It's not worth much, but i really need to learn how to store things in arrays. my biggest confusion is that i have no idea how to store something in an array, have the program run again andcontinuouslybuild the array andthen display the array in its current state (by like clicking a display poll button) and then still allow it to build more once more data is entered.Here's the whole assignment. I don't really understand how to start it and the problem above is my biggest frustration!ite a Visual Basic application that can be used to determine the best Super Bowl commercial. The choices are as follows: Budweiser, FedEx, E*Trade, and Pepsi. The application should allow for the user to enter a voter's name, gender and select a commercial from a list.
Create a Vote structure that will contain the voter's first name, last name, gender and the selected commercial. Each time a vote is entered, the information should be added to an array of Vote structures.Provide the ability to save your data to a sequential access file. The program should also be able to read an existing file of vote data into an your array of Vote structures. Doing so, should eliminate any data that may have already been in the array.

I have a piece of code written in Visual Basic:
Dim n As Double, i As Integer
n = 4
Dim Ramp_length(1 To 4) As Double
For i = 1 To n
Ramp_length(i) = Cells(13 + i, 5)
'Cells(65 + i, 7) = Ramp_length(i)'
Next i
Is there a way I can reproduce the result without declaring the array with a "fixed" length? I eventually want the code to read off a column of data with unknown length and store it in an array of equal or smaller length so it can be altered.

I'm using WinPcap to capture incoming data. Basically I'm dealing with a continuous stream of incoming data, either as byte array or as memorystream (pieces up to 64kb).
I need to check this data to see if there's a certain url and then extract it.
The url I need to find looks like this:http://201.122.38.5/data/today/798572987-589571?139805890582 The length of the 'code' after "/today/" is always the same. The IP address changes. What's the best/fastest/most efficient way to continuously check these byte arrays or memorystreams and extract the urls without hogging the CPU too much?

below is a byte array to string encoder. It uses the yEnc algorithm that is used for Usenet binaries (Usenet only supports text).
Doing a performance analysis in VS2010 shows that this is the most CPU intensive part of the application.
The encoder function is used thousands of times, so I'd like to optimize it as much as possible.
I'm using 'ReDim Preserve' instead of 'Take()ToArray', because I'm targeting .NET Framework 2.0. Is there a more efficient way of getting only a part of a byte array?
