Oct 13, 2011I call the method GetUrl below provided in a form-based assembly from a console application to get the content of an HTML page. This works fine so far with one exception. The code starts an iexplore-process in the background and this process remains active even after fnishing my program. The only way I found to get rid of this process was to kill the process, but this seems not be be a very nice and mature solution. I already read that the NET webbrowser control in only a wrapper for an activeX COM control of IE.
Question: How can I close the newly created iexploe-process in a clean way using the webrowser object?

Jul 25, 2011Is there a better way to make a form with multiple buttons opening different things than having a form that has lots group boxes for each tab. So in the begining each box will be invisible and when you click the button the corresponding group box will become visible. Is there any other way?It will be like a background image and it'll have buttons that will mask it with invisible buttons. when the button is clicked it will open the corresponding group box.

View 1 RepliesOpening Form By Type Or Name
Jul 17, 2003How to create an instance of a form if it is not know in advance which formtype has to be opened. If you want to skip the chitchat: the .NET code example is at the end of this post. First the Symantec: when we create a new form, this form has a name. If we refer to that name, we actually refer to the name of the type of object that is just created. When to use of course when reading the subject you might think: why not just pass the form to a parameter that takes a form (or control/object)?
The answer is: you don't when it is not sure, when or if a new instance of the object has to be created or, as mentioned, when the procedure is called it is not known which class has to be created. You could of course hold a bunch of created objects, but that would be a shameless misuse of memory. Imagine the following scenario (seen something like this in a post, but can't find it anymore):
You have a class that is able to trap an event, say the doubleclick of a textbox, and has to open a form when it occurs. If it's always the same form, that's easy, but what if you want it to be determined during runtime? This is a quite common story: doubleclick on article opens the detail form of that article, doubleclick on supllier opens that particular form. If you use a form variable, how do you say to the class which form should be opened? This will not work
Code:
Dim FormToOpen as Form 'you don't want to open it right away, you want to know when the time comes what form to openFormToOpen = Form1You could say FormToOpen = new Form1, but then 1. an instance would be immediately created, even if it never will be used: memory leak. 2. you can never close the form, you'll always have to use the same instance created when setting the form. Consequently, you can never open more than 1 instance using this way.
The solution: use the type. If you know the type, the Activator class will enable you to open (and return) an instance of that form at any time and as much times as you like. (The Activotor class exposes the function CreateInstance which returns an instance of the specified object)The following code creates an instance of the type form1 and shows it.
Code:
CType(Activator.CreateInstance(GetType(Form1)), Form).Show()Or for better readability, the same code split up:
Code:
Dim FormToOpen As Type
FormToOpen = GetType(Form1)
Dim frm As Form = CType(Activator.CreateInstance(FormToOpen), Form)
frm.Show()
Opening New Screen In Same Form?

Combo Box Activates On Form Opening?
May 15, 2009I have created a main form in my program to which I have added a combo box containing 12 months of the year. What I want is when the selected month is changed it should call a subroutine which does a calculation. The procedure works but the combo box acts as if the selected item has been changed as the form is opening which is not what I want as at that time there is no data loaded for the procedure to do it's calculation. So what I want to know is, is there some way to prevent the combo box from behaving this way at start up?

Forms :: Opening Form Using A Threadpool?
Sep 15, 2009I want to open a VB.net form using a ThreadPool with a maximum of 10 threads. I need to do this because, the form should open based on a live event and i need atmost 10 forms on the desktop at a time. If i open the form on every live event without using a ThreadPool, the desktop will be floaded with many forms. I am using QueueUserWorkItem method of threadpool to queue a method which opens the form. In this queued method, there is form1.show() statement called. But after displaying the form, this method finishes execution and again we have 10 threads available in the system. I somehow want to either keep this method running so that 1 thread is occupied or i want to keep the thread alive till the form1 is closed by the user. I want the 11th form to appear on the desktop, only when any of the existing forms out of the 10 (already on desktop) is closed.
View 2 RepliesMDI Child Form Not Opening Correctly
Jun 24, 2011I have an MDI form on which I am trying to open two other forms in the same place (not at the same time). One works, one doesn't. Both of these forms have the following as the very first statement in the load event.
One form opens in that location and functions fine. The other form, which is the same size, seems to spread out across the MDI form top-to-bottom wise. There is also a bar at the top with min, max, and close buttons that came from where I don't know as the form is set with no border. This form must open in the correct way as there is a menu at the top of the MDI. Anybody have any idea why this is happening? Some property or something which is different between the 2 forms?[code]...

This form has a picture box on it, if that means anything. why this child form does not open in the specified location?
