hello all,
I am working on a project related to Internet Explorer. I want my
application to be invoked by a keypress( single key stroke or a
combination). But this must get invoked only when the IE browser is
open. I learnt that SetWindowsHookE x must be used along with few
others. But my doubt is how to call my application? Can i implement the
keyboard hooks related methods in the same project as my application or
should this be else where(i.e as a new project)? wats the difference
between the keyboard hooks and hot keys... i have been serching abt
this for a long time that right now i am confused.
I am new to .NET and all these window hooks. Please help me.
thanks,
hema

news:f9******** *************** *******@ureader .com... hello kevin,
this is Geetha only.I have got some problem with the logging in with my
id,..
. dont know the problem,since i am due to complete my project in few days,
i
have created this id.Sorry for the trouble.
Has for the question u have asked.If u mean to say that this message loop
means informing the browser that my application must be invoked when a key
is pressed,then yes thats wat i want.
i have started with the BHO stuff.i think i will call the Hooks related
functionalities i.e. Installhook in IObjectWithSite .SetSite(). then it
will
go on as a normal keyboard hook.But how will i call my application's dll
from the HookProc available? mine is not a function right. My application
also uses this same interface to do further processing.i dont know how to
do
this and i am struck here.
Hope u get my id and reply back.
Thanks and regards,
geetha
hello Kelvin,
Thanks for identifying me. Yes, i have gone thru these two links already.
There jus talk abt developing a BHO,right? Or am i missing something in
there? I have completed invoking the BHO actually, i have to start with the
Hooking work on.The hook installation must be done in the SetSite method
only right? i.e. after searching whether the BHO is invoked by an IE only.
Am i right? If wrong,plz correct me.
Thanks and regards,
geetha
A Browser Helper Object can handle events spawned by the browser (such as
keyboard input). At least one of those articles tells you how to do this.

something like this. I also had this problem with a mouse hook, so i

I have a Windows form application running that contains a button and textbox.
An easy thing to do is to monitor the last time a keystroke was executed in
the textbox. I can then click the button and it will say: "The last
keystroke in the textbox was 10 minutes ago."
This is not what I want to do. What I would like to see is a message that
says: "The last keystroke in any running application on this computer was 23

I have an application that minimizes itself, and I want it to listen
for certain key commands, and when they are pressed, my program can
react to them.
So far I've gotten my application to react as I intend while the
program has focus, but when the application loses focus, the listening
stops.
I am using VS 2008 beta 2, with .net 3.5.

I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
