Sort A Structure With Preserving The Position Of Similar Numbers?
Oct 28, 2010
I am using structures in my programming and I sort the structure according to a value in the structure using IComparer.This is a simple example for what I want.
Dim MyArray(6) As Integer
MyArray(0) = 1
MyArray(1) = 45
[code]....
How does number 1 get sorted? Is it brings the newest 1 to top or keeps the old 1in the same index? In my original example (before sorting), MyArray(0) = 1 and after sorting MyArray(0) = 1.Is this the same original 1 or this another 1 (the newest one added to the array) moved to that position?In case the MyArray(0) = 1 after sorting should be MyArray(5) = 1 before sorting.
Here is my a sample of my Code:
Public Structure ToSolve
Dim Con(,) As Integer
Dim Discharge(,) As Double
[code]....
Using all these methods, how can I preserve the positions of similar number in the list? i.e. I want to bring the newest 'Similar' value to the top of the list.

I'm trying to create an enumerable class, similar to System.Drawing.Color - My goal is to have places in the code where I can define a variable as the type of my structure, then be presented a list of static values to pick from.I'd also like to use this for a property of a UserControl.I don't know if I'm using the right setup here with the class, structure, etc.I'm just trying to mimic the Drawing.Color class.I'm creating a Public Class called Person.Inside it, I have two Public ReadOnly Properties for Name and Age, their corresponding Members, and a Constructor to create a new Person.Second, I have a Structure called Persons and it has two ReadOnly Properties: Billy and Sally.[code]In my attempt, I get the full freaking .net class library in my intellisense list. Using Drawing.Color, I get a nice pre-defined list of values to pick from.No extra methods.No constructors.Just values.

I want to sort the individuals according to their fitness values descending.
' Declaring a structure
Public Structure AnIndividual
Dim XCoord() As Integer
Dim YCoord() As Integer
Dim FitnessValue As Double

Each individual has a fitness function and has its own X and Y coordinates. I just want to say if individual six (for example) has the lowest fitness value then rank this individual the first one and so on for the rest of individuals.

I'm using Visual Studio .Net 2008 on Vista. The goal of my program is to watch a directory, get file information, then sort them by thier date, and produce a updated text file. I can't seem to get my code to generate a list of files sorted by date. The code does produce a general list of files, however presently ordered in the directory. I also tried an alternate way of sorting the files by date by creating a string, removing the date using substring, then comparing the file dates using datetime.parse but it produces a exception error.[code]...

I'm using a Listview in VirtualMode, so I can 'add' a lot of files almost instantly. A Listview in VirtualMode does not allow sorting, so I need to sort the data myself. The data is stored as a List of Structure (it's faster to load than a List of ListViewItem). The code below works fine, but I need to sort based on multiple variables in the Structure. Code:

What I am trying to do is sort a datagridview and remove a row from its sorted position to the 1st row.
The problem I am experiencing is as follows:
in the source below, when the code runs "MeanRow" is populated with what is required. As soon as Rows.Remove() executes, the MeanRow datarow is lost. Why would this be if I'm declaring a new variable and simply setting it?
Code:
MeanRow = r
TabGrid(dgv.Name).Datatable.Rows.Remove(r)
Code:
Private Sub dgv_Sorted(ByVal sender As Object, ByVal e As EventArgs)
Dim MeanRow As DataRow
[Code].....

Here's the issue in a nutshell (I can elaborate if you feel it's needed). In a DataGridView I want to capture the value of the row's key column so that when the user clicks on a column header to sort the data, I can reposition to the row that was selected prior to the click. The problem is that the sorting itself, once it's done, fires the same events (RowEnter for example) that I used to determine my key value, so it sets my variable to a new value and now

How should I use linq to sort my data when my data contain both numbers and letters? For example my current linq
Dim MyQuery = From c In XDoc.Descendants() _
Where c.Attribute(Y) IsNot Nothing And c.Attribute(Str) IsNot Nothing _
Order By Val(c.Attribute(Y).Value), Val(c.Attribute(X).Value) _
Select Str = c.Attribute(Str)
Returns something like the following
13
167
172
231
44
49
Which is not what I would like it to be...
The output should be like the one below:
13
44
49
167
172
231

We have migrated our Vb6 application to VB.NET using a third party tool. Now we are in a process of Refactoring and introducing object oriented concepts in the application.
In VB6, we were using structures in many places. As a part of introducing object oriented programming,
1. is it a good idea of changing all Structures to Classes? or Is there a concept of "Generic Structure" similar to Generic collections, Generic classes?
2. Can some one guide me any source containing guide lines or best practices for applications that are migrated to VB.NET from VB6 and implementing object oriented programmaing.

It seems that on clicking datagridview column header, the column will be automatically sorted based on the column type. I have a column showing some numbers. If column type is string, it sorts "1","20","3" into "1","20","3". If column type is double, it sorts into "1","3","20" which is the result that I want. However, there might be some erros in the numbers and error messages(text) will show in the cell instead of numbers. So I cannot set the column type as double. I want to ignore these error messages and sort all the numbers. How can I do this?
Also, I need to add some background colors to different rows in datagridview. So in the column header click event, I call the bkgColor Sub to achieve this. My question is that how can I override the sorting method in this event?
Private Sub DataGridView1_ColumnHeaderMouseClick(sender As Object, e As System.Windows.Forms.DataGridViewCellMouseEventArgs) Handles DataGridView1.ColumnHeaderMouseClick

I'm creating a Website and I noticed that when the page reloads due to a postback, My variables all are unloaded so I have a Null variable,
For Example I'd Declare a String With an initial value of "" then later in the code set it to "Some Value", when a button is clicked to cause a postback, this value then becomes "" again
Is there some way to preserve variable so their values remain the same after a postback

I'm dynamically loading User Controls into a div, which I need to preserve on postback in order to call a Save method once the user is done editing them. The div and all the User Controls have the EnableViewState = True.
ASPX Div Declaration
<div id="dynamicDiv" runat="server" enableviewstate="true">
</div>[code]......
So... the controls load fine, but I can't find a way to preserver them on postback, I can't reload them because the user has already input data into the usercontrol (which is what I need to save).
P.S. I tried adding them to a list and then adding the list to the ViewState, but I haven't been able to properly serialize the control. I implemented ISerializable for the userControl's code behind but then it says the ASCX is mot marked as serializable with
Type 'ASP.controls_userControlType_ascx' in Assembly 'App_Web_pn5vxhpw, Version=0.0.0.0, Culture=neutral, PublicKeyToken=null' is not marked as serializable.

I am trying to have it so that when a user hits a button to enter a shop, it will open a popup window which will have the shop's goods. The only problem is I can't figure out how to keep the variables working between the two windows.
I need to get the variable 'gold' to transfer to and from form2(the shop window) and whatever is bought at the store to transfer back to the main window.
Right now, when I go to form2 all the values are 0, and all the variables I used on form1 are undeclared on form2.
How do I access variables from form1 to show up in form2? Is there an easier way to accomplish this than using a separate form?
