Create An Object With Controls?
Feb 15, 2012
What would be the best approach to create the following: A groupbox that contains several labels a groupbox with an array of 8 labels in it
Then the main form would have 4 of these groupboxs (object?) and I would need the ability to change the color and text of all the various labels within any of the groupboxes, using an index similar to what we could do with control arrays in VB6.
I would think an object would make the most sense but can you have control elements in an object and display them on the form?

I have an object that is defined as a global variable based on custom class. Within that class I have an event that gets fired a certain intervals. These events are fired on the same thread as where the object is declared. How do I create a global object, but have the events within that object fire on a separate thread?

I am developing an IT Asset Tracking application using VB 2005 and SQL Server 2005 Express edition. Will I need to create classes to represent objects such as Computers, Printers, Scanners/Faxes, Contracts, Purchase Orders etc or are there any other approaches.For example, if I am correct, I will have a class called Computer and its properties will include Make,Model,CPU,Hard Disk,Memory etc. Is this the right approach.
Computers can be split up into Desktop PC's, Servers and Notebooks. Would I have to create separate classes for these as well or would they be ok under the Computer class.Once I create an object from the class, how can I use the object to interact with the SQL db.I am a beginner to VB.NET 2005 therefore I am slowly getting to grips with OOP.

I would like to expand my knowledge of VB.NET and was looking at creating custom user interfaces or custom controls. The type of things I am thinking of is: [URL]s. How are those controls created? I imagine it involves using the existing controls in Visual Studio as a starting point, and altering them to suit your design?

I'm trying to create a planning program by using my own controls.I first make a control to create the entire field with a flow panel at the top for the header.Then below that flow panel I put a flowpanel for each row.Each flow panel in a row has four labels and one regular panel.The second control I make is one that creates a bar created from 2 pictureboxes and a panel. The panel is then variable based on the number of days it covers.
This control is then positioned in the regular panel of each row flow panel. (still with me??)I have not counted the amount of bar-controls that are put on the form, but there are a lot.and then I get the error: Error creating window handle.So I must be doing something wrong, but then how can one create a planning like panel with horizontal bars in different sizes depending of the amount of days.

I've created some messy code to look at the Readystate of each WebBrowser control and using boolean variable to track which WebBrowser control is done what. The time it takes to load 1000 URL's with one WebBrowser control is about 10 minutes. Multiple controls are needed for speed.
Here's the pseudocode of what I want to do:
Read a line from a file
Which WebBrowser is currently available to do work
Navigate to URL
Which WebBrowser is done loading a URL

I want to build my first user control using VB.NET 2008 Express. This control would simply inherit the ComboBox and use some event handlers to do an intelligent auto-complete function. When it's finished, I naturally want the control available in the toolbox so I can add it to forms in design mode.Is there a good tutorial on how to do this with VB.NET 2008 Express? Should I create this as a stand-alone project or as part of the first project where I will use it?

I have a form I am designing for work, and there are 3 combo boxes I want on it that display the same choice (unit of measurement selection). Now instead of 3 separately named boxes, I wanted to make an array of combo box, now I thought if I created 1, then copy pasted it would make them an array as the same name but it just lists the new one with a default name.

I was just wondering if their was an easy way to create one handle for several controls. For instance, I have 20 buttons and I want them all to do the same thing when clicked. Instead of having 20 handles for each button.click, is there a way to create one handle that can cover them all, such as a grouping or something?

How to properly create custom controls containing populated lists?For example: I need a combobox control which contains a list of products, then I would reuse this control in other project.
[Code]...
and it works but when I run the project each item is duplicated - this is because list is populated twice. First when user add a control to form, second by designer when project is started.I already found a solution to prevent adding items in edit mode, but this is not what I need. I would like to have them existing in edit mode so they could be edited at this point.
