the problem is i proposed on my thesis that i will use entirely vb.net. and i really dont have any background on C. i was searching this lockbits function and i still have to test it if it would work as fast as i want it to. err why does .net have to remove those functions i need.grr.. ill yet to google about referencing to a c# dll also using c++ to compare images in the directX stream. that means i have to re write another program that uses direct draw...err.. if you have YM do add me up macrulz2004 i really need some professional help right now. thnx a bunch for the replies

This is a very simple, top level and well documented task. I suggest reading the article I link to in my sig if you're unsure how to use google.
What you need to realise is, a full article will explain it far better than anyone could hope to in a forum reply.

Write code that checks if the server exists and times out. Make it run on a thread so it doesn't freeze your app

I have an application which allocates some thousands of objects, each containing a collection and some simple types. The objects in question form trees (the collection containing references to other objects). Setting to nothing the last reference to the root-level object of a tree takes an absurdly long time--multiple minutes. I would guess that about 1,000 objects/second are getting disposed.
Is that normal?
One remedy I have that seems to somewhat work is to have a global collection called "junklist". My class_terminate handler for these objects checks whether the object's collection is empty and, if not, adds its contents to junklist. When the application is idle, a timer handler then repeatedly empties the first item in junklist until it's spent over 100ms doing so (then it lets other tasks run, until the next timer tick). That seems to work pretty well, provided that the junk list get emptied before the application terminates. If there are still undeleted objects when the application terminates, the VB studio will be frozen until the system junks all the objects.
Are collections particularly evil, or is slow object disposal a VB6 "feature"?

I need to monitor a web page open in my browser and click a 'button' every x minutes, and if the page has changed, to pop up an alert. I have no idea if this is possible and would appreciate anyone's suggestions as to how this might be achieved. I am experienced in VB, and can understand C#.
It would not be a problem if the program had to open the web page in a browser control within the program.
Thanks.

It could be possible with the web browser control.

pseduo code
fetch page -> store source code
Timer ticks off and triggers event
fetch page -> store source code
compare previous code to new code;
if different do something
Just because we can; does not mean we should.

Use the XmlDocument to load the XML, use XPath to search for nodes, then when you find a node, read it's InnerText for the value.
