How do you know it's possible? I searched Google...and found many users asking on different forums something like you want to know. And all the answers are You can't. It's not possible. Here [^]. See for yourself. You can try the onUnload event, but there you cannot know why the page is unloading, nor stop the unload.

Will you please stop posting this ruddy question? How do you know it's possible? Have you seen it done? If so, view the source on that page. I would have to say though that I rather doubt this is possible. JavaScript operates in a sandboxed environment whereby it has no real knowledge of the browser that it's running in, and so can't interact with it in a meaningful way. This is by design.

Plus - don't put urgent in your posts. People will get to your questions and answer them when they can.

You can achieve this by creating one UserControl that receives several parameters. Once you have created a UserControl, and build the solution you will have your control in the toolbox. You can drag and drop it anywhere in you form.

Another way is to create a new Windows Control Library Project, create all your user controls there and add the controls to the toolbox specifying the DLL file.

hope it helps.

There is no such direct property for Panel control to handle its opacity.

Although you may set its back color to Transparent, it will allow you to make Panel control transparent.

Such as –

Me.Panel1.BackColor = Color.Transparent

I hope this helps Smile | :)

Hello,

Example for Transparency:
If you have inherited a panel from System.Windows.Forms.Panel,
you could try out adding this code.

protected override CreateParams CreateParams 
{ 
    get 
    { 
        CreateParams cp = base.CreateParams; 
        cp.ExStyle |= 0x20; 
        return cp; 
    } 
} 

protected override void OnPaintBackground(PaintEventArgs e) 
{}

Maybe it fits your needs!
It doesn't support DoubleBuffer.

All the best,

Martin

A thread terminates when it has no more code to execute (it gets to the end of the method you set as it's start method).

You REALLY need to understand how threads interact or you will just spend your entire time debugging things you do not know anything about. Read some tutorials, for example this one:
MSDN[^]

Generally speaking you communicate with one of the following methods:
1) Communicate with Events (ManualResetEvent, AutoResetEvent). This is typically used to signal things like "data inserted in queue", "terminate" etc. The advantage is that a thread can wait for an event to be raised without consuming CPU resources.
2) Shared data protected by locks. For example a queue one thread is inserting in while another thread reads, or the tread setting a value on a "result object" passed to it. Simple datatypes (int, bool etc) can be marked by the keyword "volatile" instead of using a lock for each access.
3) Invoking from your subtread to the main thread (look at the Dispatcher object, or the old WinForm.Invoke stuff). This allows updating for example a WinForm userinterface where only the GUI thread is allowed to change control values, but is also a pretty sollid way to ensure data is only manipulated on one thread which means you do not need to do locks (as long as you make sure the worker thread is always working on a copy of the data).

Instead of setting a terminate event you can allso raise a ThreadInterupt exception, but please notice a thread will NOT interrupt while executing your code - it will ONLY interrupt from a safe state, like waiting for an event... and in that case you can as well have it wait for a terminate event as well. Smile | :)

check SHDocVw.dll (Microsoft Internet Controls)
You can use Document property WebBrowserClass to get the HTMLDocument.

Hope this helps you.

Basically SHDocVw is a com dll.
Add following references...

.NET -> Microsoft.MSHtml
COM -> Microsoft Internet Controls

Then You can use MSHTml.HTMLDocument object to access various properties of HTML like activeelement, baseurl, childnodes etc...

Can you just try out using mshtml.HTMLDocument class?
I remember using it for somewhat similar purpose.

Or else if possible mail me your file I will look if I can do any thing.

Thanks...

HTML is a page description language, not a programming language, so it doesn't have any objects at all.

Javascript has some objects to handle XML.

google "javascript xml"[^]

I can only see half of the code that you posted. Use the "Ignore HTML" option when you are posting htlm code.
