Display For Both Arrays The Elements Using For Each Statement?
Oct 21, 2009
I read and the display values associated to a unidimensional array(called vec that has 5 elements) and a multidimensional array called
matr(that has 4 elements).And I'm displaying the associated values for each of the 2 arrays (vec-unidimensional array and matr multidimensional array).My problem is that I want to display for both arrays the elements using For Each statement.
Here is the code:
Module Module1
Sub Main()
Dim vec(4) As Integer 'declarare tablou unidimensional -vector de numere intregi
Dim matr(2, 2) As Integer 'declarare tablou multidimensional -matrice 2x2 de numere intregi
vec(0) = 45 ' setam primul element din vector la valoarea 45 -primul element are index=0

I'm having a problem to deserialize a XML to my class. It was working fine until a put the array det within the class. I put a watch just after the deserialization occurs (data = Ctype(...)), and I can see that all the informationswere loaded (ide, emit, dest) correctly except for the det element: The det whose nItem=1 attribute is loaded, but det whose nItem=2 attribute is not. With the watch, I could see that the object was loaded like a single variable, not a vector as I specified in the property declaration.
Below is where the deserialization happens when the button is clicked:
Protected Sub btnDes_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles btnDes.Click
Dim data As New nf
'DeSerializacao XML
Dim Deserializer As New Serialization.XmlSerializer(GetType(nf))

I have a control array of custom picture boxes on my form, say PibBox1, PicBox2 etc. Now, I want to access the individual click events of this control arrays. For eg: If we have three PicBox1, PicBox2, PicBox3 on the form, I want to move into the click event of each of these and assign a value to a variable PicSeletced =1, PicSeletced =2, PicSeletced =3 accordingly as the PicBox1, PicBox2, PicBox3 are clicked. But I don't know how to move into the individual click events of the control array.

I have 3 arrays setup for use in my program. The first array has item level detail and will have a known number of elements. The second array has more of a table level detail and will have an unknown number of elements that will need to grow as the user enters data The 3rd array will also be of unknown size but matching the second array and will be used for indexing purposes at runtime.The question is what would be the best and hopefully fastest way to keep these arrays as small as needed while being able to add new elements on the fly without rebuilding the entire array. Ideally I would like the code to run as fast as possible in as little memory as possible.

I need to set up a list consisting of arrays of two elements. Simple, right?
Like: (code snippet):
Dim strDataPoint(1) As String '2-element array
Dim lBiasCurve As New List(Of strDataPoint) 'list of 2-element arrays
Dim lPwrCurve As New List(Of strDataPoint) 'another list of 2-element arrays
But this gives me an error msg on 2nd and 3rd line: type strDataPoint is not defined....

I want to create a file upload client for uploading.com and I wanted to know if it is possible to make an application that lets you select a file from your hard drive, press an upload button and then the app will process it just like the website processes the file when you use a browser.Also I want the app to display the progress bar that the website displays when you upload, and when it's done, it has to get the URL for the uploaded file and display it in a textbox.Why not just use the website you ask? Well, I'm planning to make this into a bigger app but nothing will really work unless I get this to work first, so I have to start here.

I have two lists of strings. One is a list of all students in a class and the other is a list of students in the class that completed an assignment. The two lists are part:whole. So we have two loops for copying elements and displaying them in a list box for only the students who did submit.
Dim f As Integer
f = 0
Dim h As Integer
h = 0
While (usersinclass.Count > f)
h = 0
While (usersidthatsubmittedassingments.Count > h)
[Code] .....
What I need is the remaining portion of the "usersinclass" list. (i.e. The students who did not submit). I tried an Else statement BUT with nested loops, every element is guaranteed not to match at least once, so I was getting elements that shouldn't be there. So, is there anyway to run the given lists against each other again to pull out the remaining students? (preferably with no repeats).

I am new to VB and seeking to create a visual basic program which controls the display of several on-screen elements depending on a single value input by a user. The user can enter anyone of 2500 values and depending on the value entered, five different display elements on the screen will change color or text. The program's response to a given input value never changes, in other words if the user enters 279, the five different display items will always be the same. However, there is no real pattern to the display items that would allow for programming an anticipated response to the input value.
My thinking is to create a large and ponderous "lookup table" in visual basic - I am assuming this an be done but perhaps there is a different or better method. I plan on creating the lookup file in Excel but was assuming I'd need to export it to something that VB could easily read. Any suggestions on the best way to do this? Does the lookup table reside as a separate .txt files someplace or something like that? [Code]

I have tried a few things like converting HTML to XML and then using an XML navigator to get input elements but I get lost whenever I start this process.What I am trying to do is to navigate to a website which will be loaded using textbox1.text.Then download the html and parse out the input elements like . username, password, etc and place the element by type (id or name) into the richtextbox with the attribute beside the name.[code]Any clues or how to properly execute an HTML to XML conveter, reader, parser?

I created a method and pass the element type, id, and any inner text that instantiates a new html element. The last statement: Me.Controls.Add(element) adds it to the end of the page, but I would like it to be inserted in a specific position (between 2 divs within a form). What I am describing is very similar to this post on SO here, although it was for javascript.

I am doing in my Visual Basic Reloaded:second edition school book. Ok here is all the information the case problem gives me and what it wants me to do.JM Sales employs 10 salespeople. The sales made by the salespeople during the months of January,February, and March are shown in Figure 8.52. The sales manager wants an application that allows him to enter the current bonus rate. The application should display each salesperson's number (1 through 10), total sales ammount, and total bonus ammount. It also should display the total bonus paid to all salespeople. Be sure to use one or more array in the application.Then it gives you a table with the salespersons 1-10 sales amount january February and March.(this is the figure 8.52)Here is a duplicate table of it below.
Salesperson January February March
----------- ------- -------- -------
1 2400 3500 2000
2 1500 7000 1000

I've been working of a Visual Basic Windows Form in Visual Studio 2010 as my first little VB project. It's a form which runs a stored procedure on SQL. I have this all working, however, the stored procedure has a PRINT statement execute if a duplicate is found and stops. What I'd like to do is have this PRINT statement display on the Windows form MessageLabel (label) or have a "successful" message displayed if there is no SQL print statement.

I am trying to create a program in vbfor this problem: "A TV set is purchased with a loan of $563 to be paid off with 5 monthly payments of $116. The interest rate is 1 percent month. Display a table giving the balance on the loan at the end of each month". It must have 1 button and a list box that displays successive balances, contains loops to balances, loop code includes output to the list box, List box displays 2 columns (one for month and one for amount owed) and 5 months are displayed and the amount owed for each. The Amount Owed should go down each month from month 1 to month 5 where month 5 will equal to $0.00
Here is my code so far but somehow the 1 percent interest i cannot get to add on each month so I am not getting the write answer.
Code:
Dim rate As Decimal
Dim loan As Double
Dim pay As Double

I am having problem with the coding of this (endless loop) and formatting of summary boxes before tests are complete that should not happen. (the overall goals is to have a separate validation procedure that does not calculate or dat displays are not performed until after call function is complete and valid. The validation that takes place are that two boxes are filled in - one is text and the other is a numeric value. (using vb 2008)

In VB6 I load a recordset containg all of the records (6 fields per record)in a table into an XArray and then manipulate the records in the array and then write them back to the original table. The array issorted by the first field (1 to maybe 8000 or more) I need to find records in the array by an ID field and then move them (because of some external criteria that happens many times) from say number 400 to number 375. Then all of the other records between 375 and 399 were renumbered up 1 to fill the gaps left by the move.
The XArray worked well as it could find and also move to a next record easily to facilitate the revisions to each record quickly. Everything is done in VB6 in code and nothing visual needs to be shown to the user until say 2000 of these external changes are complete. What is the best, most efficient way to do this in the .Net framework in VB2010. Datasets, Dataviews. tableadapters, arrays. enums ?

I have a VB.net console app and I am opening a function in a dll written in fortran. I am passing 3 arrays through the function by reference. When they come back out the otherside they ahve all tunred to arrays of only one element And that element is 0.I read on the internet somewhere that when doing this kind of thing it is a good idea to only pass the first element of the array into the function.I tried changing my function declaration to accepting single elements rather than single dimensional arrays, and now the arrays are the same length before and after the function call, but they don't seem to be changing at all, so i'm not sure that this is working

the statement Dim state(49) As String and maintain a list of certain states. The list of states should always be in alphabetical order and occupy consecutive elements of the array. The buttons in the program should give the user the following options: (a) Take the state specified by the user in a text box and insert it into its proper position in the array. If the state is already in the array, so report. (b) Take the state specified by the user in a text box and delete it from the array. If the state is not in the array, so report. (c) Display the states in the array. "
