VS 2010 Custom Objects And Properties
Nov 13, 2011
I'm working on a project where I need to information on all the monitors connected to a computer and then write a configuration file based on that. I can already get the screen information by creating a new instance of screen and reading the information such as index, bounds and everything else.I'm trying to create a virtual screen object to hold the information from the screen so I can work with it, or add other properties to it.[code]This all works perfectly how I want it to. Except I would like to do one more thing. How can I make it so that instead of getting Virtual_Screen.Top, I could get Virtual_Screen.Bounds.Top? That way I could create other properties such as Virtual_Screen.Border.Top..I have no idea how to code, or what that would be called. It's hard to search for something you don't know the name of.

I am using a loop to update properties of each object of a set of custom objects. The routine knows which controls to update because the controls value is not empty, I don't want the routine setting the corresponding properties to nothing when the control is empty. Now I know how to do this perfectly fine with IF statements such as:
CODE:
But this feels really redundant doing that same IF block over and over for each property/control combination, I thought about creating a separate routine that takes the control as an argument and does all the repetitive IF blocks but I don't know how I could also pass an object property to tell the routine to update that particular property.

What I've done is create a User Control Library (Project) and I've added a single User Control to that project. The control contains a single FlowLayoutPanel, and I created a Property on the control itself to pass the FlowDirection from the Control to its FlowLayoutPanel child.
Build, reference, component appears in the Toolbox and everything works fine, but the property on the control does not appear in the Properties window when I go to edit it at design time.

I need two seperate lists, which every item is Integer, String, Bitmap - and one which every item is Integer, String String. However I don't know how to do this, or even where to look - I've googled for custom objects and custom object lists. What I'm trying to do is this.Custom Object1 is Integer, String, Bitmap Custom Object2 is Integer, String, String
In one thread I'll be adding items to List1(Of Object1), and processing them, and adding the results to List2(Of Object2), however I need to be able from other threads to look at the list and say only give me the items where Integer = (my thread ID), is this possible? Any help, or even links to information that would be relevant to this request would be helpful?

I'm fairly experienced with making user controls and have never had this happen to me before. All of my custom properties (gloss opacity, border color, header color 1 and header color 2) are all grayed out in the properties window on the form designer when I try to add my groupbox to a form.
Here's my
Imports System.Drawing.Drawing2D
Public Class DanGroupBox
Inherits ContainerControl
Dim _GlossOpacity As Integer = 50
Dim _HeaderBackColor1 As Color = Color.Silver

I have a program like this.
Module Module1
Public Class Mstr
Public Property Prop1 As String
Public Property Prop2 As String[code]....
But it is not working as I expect it to. You can see it from.The DtlsB properties of all three DtlsA objects are having values from last iteration.

getting the following error Unable to cast object of type 'System.Object[]' to type 'OrderService.webdirect_WebLinesRow[]'. On the line
webdirect(web_companyID, web_locationCode, web_customerNumber, web_orderNumber, web_orderReference, web_orderDate, webLinesArray.ToArray(), o_Company, o_LocationCode, o_CustomerNumber, o_OrderNumber, o_OrderStatus, o_OrdDescrip, webRespArray)
I created the webLinesArray.ToArray() array as such
Dim webLinesArray As New ArrayList()
Am I missing an additional cast or something ?

I've populated a PropertyGrid with a custom class. How do you create and display a sub property similar to Size (Height, Width) which has two values or Point(X,Y)? For example, the class is Test and the property is Item as string. I want to expand Item to have two sub properties, A and B.

' What I am looking here is, I wanted to copy all the (inherited object properties of class Z is common for both A & B) common property values of object A into object B without accessing properties independently eg: objB.Name = objA.Name (Don't want to do like this)

I have an application which is grouped in a MainApplication and serveral Modules (DLL's) The Main Application is basicly a Form with a NavigationBar on the Left Side (like in Outlook 2003) and an MDI-Parent. There is also a Simple Login Routine on this Form. I store the UserName after Loggingn to a Property. The DLL's holds functionallity and Forms for various Sections for example there is a Employee.dll which holds functions and a form to show all Employees.
On Loading of the Main Application I loop trough all dll's in a "Module"-Folder and extract NavigationItems from them which I add to the MainForms NavigationPanel. I don't have a reference to the Modules because I want to make it as flexible as possible so that it is possible to delete a Dll form the Module directory in order to remove the functionality from the MainApplication. The Modules could work also without the MainApplication if they are Complied as an exe insted of DLL of course. This works fine so far.

Is it possible to change the default properties for different objects in the VB6 IDE (I'm sure any version would be similar, but this is the one we are currently using in my programming class in school). For example, is there anyway that automatically, when I create a Label, that it could already have AutoSize set to false, and BorderStyle to Fixed3D, etc.? I feel as if it would work greatly with the amount of time taken to layout my programs.

For good reasons I would like to have something like truckA = truckB + truckC where only the loads of the trucks are added, not the license plate numbers. Also I don't really want to return a new object (lots of overhead), just change one or two of the properties. Only thing I can come up with is truckA.Load = truckB.Load + truckC.Load, or at best truckA.Load = truckB + truckC which still doesn't look elegant, and - worse - still requires the creation of a new Load object.(this is just a way of stating my problem; the real objects are quite big and complicated) Currently I have a Sub isSumOf so the code reads TruckA.isSumOf(truckB, TruckC)

I have a group of objects stored in an arraylist. These custom type objects have a number of properties from their underlying class . I want to use one of the properties to sort the array. I cannot determine which Array.Sort method to use.
I want to sort based on an integer property. Virtually every example I can find involves sorting strings.
So, assume the Objects have the following properties.
Obj.name as string
Obj.ID as integer
Obj.Alive as boolean
The objects are kept in an arraylist called FriendsOfMine.
I want to be able to order the list by Obj.ID, both ascending and descending in value.

In my software course, each time we submit an assignment, we have to include a document with the starting properties of each object in a form.
E.g.
TextBox1
Location: 241, 115
Name: TextBox1
Size: 100, 20
TabIndex: 0
It's a real pain to scroll through the properties viewer and copy and paste each customised value for 30+ objects on a form... I was wondering if there'd be an easy piece of code or way about getting an (at least partially) automated printout/view of all the properties of the objects.
Was thinking some sort of private sub I could past into the bottom of the program and run on load, that gets all objects, and outputs the non-default properties to a report or something?

I need to migrate from Excel 2003 VBA to Excel 2007 VBA. When Microsoft introduced Excel 2007 it removed many objects from the previous versions and added some new objects. Also it hid some properties of particular objects. These hidden properties can be viewed by going to the object browser, right clicking any object and selecting "Show Hidden Members". My problem is I need to access these hidden properties. Is there any way I can access these properties. I can successfully migrate from Excel 2003 VBa to Excel 2007 VBA with the same functionality?

I have a custom class (Class1) with a bunch of properties. One of the properties of this class is another custom class (Class2) with its own properties.I have a property grid with the selected object set to Class 1. I can see Class 2 as a property, but i would like to expand Class 2 to show its properties in the same property grid.
Im basically trying to do the exact same thing as the Font Class on a form. If you look at the properties of a form in the designer, you can see the font property. You can then expand that to show the properties of the font class.

In the form design I set up a TableLayoutPanel, 20x20 cells and in cell (1,1) a PictureBox (called Target) containing the image of a small target. The properties box for Target shows some very promising properties, Column and Row - and if you overwrite the values in the properties box, the PictureBox obligingly shifts to the corresponding cell position in th design. However in VB it is not possible to refer to Me.Target.Row or .Column - neither appears during coding in the menu of properties, and deliberately coding either of them produces an error like
Error 1 'row' is not a member of 'System.Windows.Forms.PictureBox'.
1. Why does the properties box show properties that cannot be altered programmatically?
2. How can my program move Target around in the TableLayoutPanel?

I created a custom datagridview column for a progressbar and included customizable color properties but I can't get them to work right. After compiling, the properties show up correctly in the Edit Columns popup editor, but changing the values has no effectThe designer generated code shows the original values and manually changing them there has the desired effect(I know you're not supposed to, just testing). Here is the code for the column even though I don't think the issue is stemming from any coding errors there.
Imports System.Drawing
Imports System.ComponentModel
Imports System.Drawing.Drawing2D
