XML - How To Deserialize Elements And Arrays
Nov 26, 2011
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 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 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 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.

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. "

Ok, so I'm playing with some FTP profile files that are written in XML. I'm trying to get the program to be able to read the current users settings and fill in or remove servers they do or don't have access to. So the XML looks like
<?xml version="1.0" encoding="UTF-8" standalone="yes" ?>
<ftp>
<servers>
[code].....
it's probably more cosmetic than anything but the logic just doesn't flow to look over 'server' and not 'servers'?!

I have an XML document that I am deserializing (VB .NET 3.5 Framework), changing some values, and the serializing again. The original document has several XML Comments in it. When I go through all the deserialize/serialize all of the comments are lost. Is there a way to preserve the comments? If not, is there a way to add comments on serialization without having to walk through with the writer and manually add all of the comments back in the appropriate place?

How do I serialize and deserialize my main form (and its controls, subcontrols, their values, etc.)? Edit, for clarification. Currently I am writing the current value of each control to an .INI file, one by one and reading it back when the program is next run. Every time I add a new control, I have to remember to update that save/load .INI code.I just wondered if I can do it in one call, or a simple for loop iterating over all controls on the form.Btw, I use only simple controls like edit box, radio button, combo box, checkd listbox, the most complex thing I have is a datagrid, but even that is not linked to a databse.Accepted answer "can't. I will probably code my own, along the lines of ...
