Create A New Instance Of A Control To Copy It?
Jan 27, 2010I am trying to create an instance of a control to copy it.
Dim NewPanel As New Panel1
Is not working. When you create an instance like this, the "Panel1" wont show up in the list of classes, so it says "Panel1 is not defined".I have heard of control arrays dissappeared in VB2008,but still,is there any way to create a new instance / copy an already existing control or let a control appear like it was when you made it in VB so you can open multiple Panels like they are child forms?
EDIT: I know you can do:
Dim newPanel As New Panel
newPanel = Panel1
Form1.Controls.Add(newPanel)
..but that's not what I want, because that makes you can't edit the controls inside the new panel.
Transfer Control To The New Instance In A Single Instance Application?
Jul 15, 2011I have a single instance VB 2010 application I know how to communicate with the next instances run through the StartupNextInstance application event. The usual way of working with this is parsing command line arguments of the new instance and continue execution of the old instance. What I would like to do is replace the running instance with the new one. Is there any way to do this other than disabling the single instance property ?

View 1 RepliesCannot Create An Instance Of My Class
Feb 24, 2010I am working on an ASP.Net 3.5 solution that I did not originally build. I added a class file named Incident.vb to the App_Code folder like I always do.But in my code behind of a web page, I usually create an instance of a class like:
Dim oIncident as New Incident
But after I type "New", normally I would see my class file he intellisense but I do not. So it does not seem to be able to find Incident.vb. I have not seen this behavior before. Trust me, my class is correct. I have created many class files like this.[code]...

View 5 RepliesUser Control Not Set To Instance
May 22, 2010I've created a user control (an "extended" rich text box: extended with standard editing). I used the same procedure I used to previously create a different user control (which works just fine)
That is, I:
- Create a Class Library project
- Then Add New Item> User Control
- Then delete the initial class that was added automatically (usually named Class1.vb)
- Put all of my code and components into the user control class.
It was running (with start degugging in the IDE), but I must have done something different since I now get an error:
"Failed to create user control ExtendedRTFBox.ExtendedRTFBox
The error message was 'Object reference not set to an instance of an object'
I tried explicitly creating a public new in the 'ExtendedRTFBox' user conrol. I tried adding a class and adding a dim textBox as New ExtendedRTFBox. I cannot add a starup object in the project properties application tab.

Create An Instance Of An Object/webpage?
Jun 7, 2011if i create an instance of an object/webpage, is that a complete new object/page based on the original or does it does it just make it accessible? i am almost sure that it creates a new object/page but i would like confirmation. in other words what is the result of this code?
dim Page2 as new Page1
dim Page3 as new Page1
would this create 2 new pages that i can "customize" separately and add different controls to each? heres a brief description of what i want to happen:the user will be viewing Page1 and when he clicks btnCreate i want a page that i created in the designer to be shown and its name and other variables to be determined by what the user chose for room options in Page1. i need "new versions" of this page to be created because multiple users will be creating multiple rooms. i understand that there are more lines of code involved in creating pages and i do have more questions regarding those but i will wait until i confirm that dim Page2 as new Page1 will create a new page. like i said im sure that this does create a new page but i need confirmation. also if it does create a new page, how do i get it to show. i know that response.redirect will redirect me to a dif page but i want show this new room on top of the old one.

Aug 21, 2009I'm working through a book that does not provide a lot of example code and what it does provide is in C#. The book refs vs 2005 but I'm using vs2008. The author asks for the user to create a solution with two projects, one winforms and the other a class library (called DependentAssm). The class library is added as a reference to the winforms project In the class library, he asks one to create a new class called SayHelloComp. The project created a file called class1.vb, and a class called class1 which I renamed to SayHelloComp. I left the file name alone, that's ok right?
View 4 RepliesHow To Create New Instance Of Web Service / Config
Sep 2, 2010So I get thrown an exception right when I try to create a new instance of my Web Service that says:
"Could not find default endpoint element that references contract 'KBBVehicleService.IVehicleInformationService' in the ServiceModel client configuration section. This might be because no configuration file was found for your application, or because no endpoint element matching this contract could be found in the client element."
This is a web service that will connect to Kelley Blue Book. I know I need a new endpoint entry in my Web.Config, but what does this look like? The one I added looks like this:
<endpoint address="http://localhost:3300/KBB.svc" binding="basicHttpBinding" bindingConfiguration="BasicHttpBinding_Default" contract="Services.Client.IVehicleInformationService"/>
But it doesn't work. Still throws the same exception at the same place.

VS 2008 When To Create A New Class Instance
Jun 22, 2010I understand if i was to create my own class i would need to declare a variable with the new keyword to create an object to access the encapsulated methods properties etc, unless they were declared shared.
dim myVar as myClass = new myClass
But in this next example is where i have become confused. i have added the mschart control to the form and used the hittest function with the following code.
Dim myVar as hittestresult
myvar = me.chart1.hittest(e.x,e.y)
Why wasn't it necessary to create a new instance of the class 1st. Does the hittest function return an object or a reference pointer to the object. To clarify what's the protocol for when & when not to create a new instance of the class in use.
Doc Opens In New IE Instance Not Web Browser Control?
Jan 18, 2009I'm just starting to write a program to manipulate some intranet based databases using the web browser control, but have a problem with one specific database.I can log in from the start page of this database from my browser but it then opens in a new instance of IE (I think it's the java code (not java script) which does this when the page loads).How do I get it to open in my browser?OK, I can manipluate it with a doc object, but would prefer to do it in my browser for consistency, as the other databases open fine in my brower.I can't be more specific but could post the html text if necessary.Currently using the built in web control with VS2005 running on XP.
View 2 RepliesCreate A New Instance Of The Moblist Class Each Pass?
Jan 13, 2011I have an application that reads another processes memory.I initially had multiple scanning threads for the various areas I needed to read.This was processor intensive so I decided to go with the observer pattern.All was well except that I am having a weird behavior.Here is what is happening.I have 2 radars (overlay and mapped)Both have a watcher class that attaches to the memory scanner and is notified on a new list of mobs.so I open radar 1 (mapped) it attaches it's watcher to the scanner and waits for mob list update notifications
Open radar 2 (overlay). same thing happens and another watcher is attached.all is well and good so far.Now there are properies on the mobs in the list, one of which is IsFilteredOut.This property is set in the radar code after it receives the list. Now the weird behavior is that no matter what I do, the second radar to be opened changes all the properties of the mobs in the list of both radars.It is as if I am passing the list by ref, but I am not.I actually create a new instance of the moblist class every time I pass the list.Here is the notify code. As you can see I create a new instance of the moblist class each pass.
Private Sub NotifyMobListUpdated(ByVal Mobs As List(Of MobData))
If Mobs IsNot Nothing Then

When I run the "MainStudentScores" form and click on a student with three scores separated by the "|", it should give me a Score Total, Score Count, and Average.
