VB / VS 2010, Incrementing Control Names At Runtime

Apr 25, 2012

I am coding an invoicing application. The user should be able to add a new line to the billing section of the invoice by selecting a product from a ComboBox, which subsequently fills out various other fields (price, description, etc) based on the selected product.

My problem is this: When the user adds a product, I would like the program to automatically generate a new line for the next product. It seems like the only way to accomplish this would be to create a new set of controls with an incremented name, i.e. Product1, Price1, Desc1 for the first product, Product2, Price2, Desc2 for the second product, etc. Is this possible, or am I going about it all wrong?

VS 2010 Creating The Effect Of Control Selection At Runtime

May 16, 2010

At design-time, when one clicks a control it is selected and this state is depicted with a frame drawn around the control. I would like to know how can I mimic the same effect at runtime; that is, how can I draw a similar frame around a control when the user clicks over it?

VS 2010 : Change The Parent-child Relation In A Treeview Control At Runtime?

May 5, 2012

I want to program a water supply pipeline network in a treeview control. It has five node (junctions). The parent-child relation is based on a parameter (say pressure). Initially, the node 1 is parent and its child nodes are 2 and 3. The node 3 has child nodes 4 and 5. At run time the pressure changes. Now, node 3 is parent and its child nodes are 1, 4 and 5. The node 1 has child node 2.

Construct Object Names At Runtime?

Jul 15, 2011

Is it possible to construct the name of an object (in this case, a Panel control) at runtime?

What I want to do is change the Backcolor of one Panel that is a member of about fifty panels. I can get the string of the name from the Sender in a RadioButton CheckedChanged event. So what I want to do is something like:

PanelName = sender.parent.name & ".BackColor"
PanelName = Color.Red

(I realize that the syntax above is invalid. I'm just using it to try to get the idea across.)

I can do what I need with big, fifty-element Select Case blocks, but the code is so repetitive that I was hoping there was a more elegant way.

Mass Renaming Of Control Names?

I'm making an art program involving 8x8 squares on a grid, but there are 64x64 grid square PictureBoxes for each grid square. Meaning there are 4096 picturebox squares to be setup.

I'm having them names like pic0001, pic0002, pic0003, etc... but re-naming them individually would take me forever. Is there a way to mass re-name them at once?

Control The Element Names Of Serialized Subclasses?

Jul 5, 2011

Let's say I have the following class structure (simplified from my real-world problem):

Public Class PC_People_Container
Private _people_list As New List(Of PL_Person)
Public Sub New()[code].....

If I were to serialize this, I'd get the default assigned node names in my XML. That means my root is named PC_People_Container and each person in the list is marked up as PL_Person. I know I can change the root node using <XmlRoot(ElementName :="PeopleContainer")>. The trouble is doing that for the subclasses. I can't use the <XmlRoot> tag on PL_Person class because there can't be two root elements, and IntelliSense throws a fit when I try to use the <XmlElement> tag on a class like I would on a property. Is it even possible to control what those subclasses are named when they're serialized as child nodes?

Listbox Control Item (ugh) Multiple Names?

Feb 12, 2010

Okay, so the title was horrible. I know that. Here's what I'm trying to do:I have a lot of data that's coming from a database and being adding to a listbox. The data that's coming from the database is a unique ID, and a name. Is there any way I can make the item contain both the ID and name? I know I can append it, that's not what I'm looking to do. I need a way to be able to either get the ID, or get the name, while displaying them both.I have gotten as far as creating a class:

Class Item
Property ID as Integer
Property Name as String

Setting Names To Rows In DataGridView Control?

Oct 12, 2011

VB.Net's DataGridView supports naming columns, but I was wondering if it could somehow do the same for rows, so that we could use something like this:

With DataGridView1
.Rows.Add(4)
.Rows(0).Name = "Setting1"

[Code].....

Do you confirm that it's not possible and we must use numeric indexes to refer to row numbers?

Interface And Graphics :: VB ListBox Control Display Names?

Dec 20, 2010

I don't usually use VB but now I must for an assignment. I would like to know if it's possible to change the display name for an object on a listbox. For instance, if I add to it a user defined class, there's a way to provide it's display name, instead of converting it to string and then add it.

This is what I have

Dim format As String = FormatOutput(object)
Lista.Items.Add(format)

I would like to have the same output, but instead add the object.

Note: if such is not possible, then how can I associate the list box selection to the actual object? Doing it by index is painfull, because I'm using linked lists (ie., instead of arrays).

Note 2: python has a __str__ method which is called by default when the object is cast to string. Is there anything like it in VB?

Referencing XAML Custom Control Names And Properties Within Code Behind?

May 13, 2009

I've created a Custom Control, and I will be placing a large number of instances of that Custom Control on my xaml page. In working with that Custom Control in the VB Code Behind, how do I do the following?

How do I reference the name of the Custom Control (in my VB code) which was clicked with the MouseLeftButtonDown event? For example, if I have 10 instances of my Custom Control in xaml, each with a different x:name (say 1-10), when a particular instance is clicked, how can I see which one was clicked? I've tried a number of things including e.OriginalSource.Name (which returns the component within the control which was clicked and not the name of the instance of the control). My Custom Control consists of numerous parts and pieces (Rectangles, Lines, Text, etc). Each of these items is a part of my layer. In VB code, once I can reference a particular Control, how can I hide or change certain parts of that control (such as hiding a Line, and changing the text). Also, I need to modify more than just the control which was clicked, so I need to be able to access properties of all of the controls, not just what was clicked. For example, if I click Control instance Test1, I also need to modify Test2, Test3, and Test5 in some way.

Here is some test code I through together as part of a Silverlight project using MS Blend 2. My control is much larger, and I need 200 - 250 instances/copies of that custom control, so I really need to know which control instance/copy was clicked.

My UserControl:

<UserControl
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"

Communications :: Incrementing An IP Address?

Jul 11, 2011

I am trying to make a simple port scanner to scan a rang of IP's so like 192.168.4.245 to 192.168.5.100. I am using Visual Basic.Net 2010 and am having trouble converting the IP from a String to a Long so that I can increment it and convert it back to a String. For some reason VB.Net 2010 doesn't include the winsock controller and therefore I am having problems finding a method that works similar to inet_addr() which makes conversion much easier. I found an example on one of the forms here

Code:
Private Sub Command1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Command1.Click
