Hi,
I was working on a screen capturing application which must do its work
when a key (eg: CTRL) is pressed while the application is resides in
tray as a notification icon.
I mean, while my application resides as a notification icon, it must
do the work when a specific key is pressed such as CTRL.
Is it possible to work for an app which hasn't got focus and which is
inactive?
Note: I've done capturing coding part, the thing i want to do is to
implement a kind of keypress listener while user exploring other
windows and my program is inactive as well, but is in the tray bar as
notify icon as minimized.
A good example for my question is that program: http://www.wisdom-soft.com/downloads...hunterfree.zip

So you say i need to call Windows API a kind of p/invoke? This link
contains no VB example so i don't know how to declare and which Proc
type i must use.

I have seen a few articles on codeproject.com about using key hooks.
You might try searching there for some examples: http://www.codeproject.com/info/sear...ey+hook&sbo=kw

You either need to install a system wide keyboard hook in C++ (not very
smart, and a little tricky) or register a hot key.
Here's how to register a hot key in .NET. http://www.dotnet2themax.com/ShowCon...0-c2bb7075ba78
Otherwise do a search for SetWindowsHookE x API and prepare to get your hands
dirty. :-)

Cmoya, that link was "awesome" very thanks, but i need to add
something to facilitate people's work who are searching similiar help.
One thing is missing in article:
If you do not use "Imports System.Runtime. InteropServices " as
declaration, you get "marshal is not declared" error as well. After
this addition, it works.

Form.Leave does not fire when showdialog is called on another form.
Anyone have any idea how to capture the form losing focus?

I have a VB.NET application that consists of a toolbar and a subwindow
that I want to function together and not independently. So when I
give focus to one, I want to make sure that the other is visible on
the screen (brought to front, right behind the one in focus).
I've played with the activated event of each form, but everything I've
tried so far fails, as it's a pretty cyclical process that gets
initiated. I'd love any help......

I have a form with progress bar.
I'm querying sql server with large number of records(around 1 lakh)
for export
The records are written to a text file
I'm showing the process running by updating the progress bar
If the form loses focus(i.e selecting any other application) means
progress bar is not updating
The coding is below

I have searched and searched, with no luck.
I have a Form that has several event listeners in it (Keypresses, speech
recognition, afew others). When I click a component in the form (such as a
button), the form itself loses focus.
How can I get it back? I have tried this.Focus() from w/in the form in a
timer with no luck as well as several other things.
Thanks!
