You could set the Visible property to false (It explains in that guide above) or take a look at this

Yea, thats clears quite a bit of stuff up tho... BUT i don't suppose you could code me an example, say

Removing WEB (which is a WebBrowser)
I now nothing about the Controls collection so i'm not sure how to use the Remove method :S HELP ?

I've explained as far as my knowledge goes, I'm not 100% sure why you want to create a web-browser on the fly, But anyways as i said above your best bet is just to set its visible property to false

Thanks for your help. You've done the forums proud

I wanted to make and delete webbrowsers on the fly for the purposes of clearing cookies, IE keeps them in memory, so as well as deleting them you need to close the browser, SO, i figured that if i could remoce the browser after or before clearing cookies i can start fresh with a new browser

Any more comments ?
PLUS : I RATED YOU

Hmm, I'm not 100% but how often would you be closing the browser? and out of interest why are we deleting cookies?

Closing a browser and opening a new one whenever the end user wants to, usually every minute or so, and the reason i delete the cookies is because my porogram is logging different accounts into a game that sets session cookies, so i need to close the browser and clear the cookies and open a fresh browser

I hope that clears it all up

Permission to bump ?
Permission Granted...

BUMP, i still need help with the deletion of objects

Firstly apologies for the time taken to respond. Pino did point the thread out to me earlier but I have been somewhat busy.

What you need to do is find the program ID of the web browser control. Now in the past I have looked in the registry, but you can find it also in the object browser and it will consist of the library name and the control name. In the case of the web browser control this is:

SHDocVwCtl.WebBrowser

You can therefore add the control to your for dynamically as follows:

Set wb_dynamic = FormName.Controls.Add("SHDocVwCtl.WebBrowser", "wb1")

You'll notice that on using this, the library generates an error and tells you, you are using the wrong program ID. Don't worry this is normal - you need to change it to the program ID that it tells you, which in this case will be:

Set wb_dynamic = FormName.Controls.Add("Shell.Explorer.2", "wb1")

This doesn't only apply to the web browser control, the same method can be used to find the program ID and dynamically create any control. Be sure to declare the object WithEvents if you intend on using any of its events.

To remove the control you use the remove method. This will destroy the control and free its memory. You reference it through the name you gave it in the second argument of the add function:

FormName.Controls.Remove("wb1")

I assume you are talking about the (0) member of a control array that you created in ther IDE. If that's the case then you can't delete them at runtime and as suggested above all you can do is to set their visible property to False via code.

Sorry, will try to add this to my tutorial so people won't get more confused. I'll take it as constructive critisism...

Prehaps just add a line about how to use the object browser to discover the program ID, then your article can be applied to any control.

Good article though

[NoteMe]

Thanks. Good idea. Will try to update it this weekend.

No, i mean i have no control arrays at all, i simply have the object placed at Design time that i wish to remove from the Program at certain points,

Thanks for your patience people

You cannot destroy an object created at design time. If you want to do that you have to create it at runtime like I described above and also descibed in NoteMe's tutorial.
