Controling a progressbar by its handle

[=?Utf-8?B?R3V5IENvaGVu?=]

Hi all

I use vb.net 2005
Lets say I have the handle number of a progress bar from program1.exe
Can I change the value of the progress bar from program2.exe using this
handle number?

TIA

P/invoke 'SendMessage' + 'PBM_SETPOS'.

If there were, presumably Program1.exe would "fix" the progress bar soon
after program2.exe changes it.

If you are developing both program1.exe and program2.exe, then there should
be a way that is easier. If you are not developing program1.exe, then, what
makes you think that program2.exe knows better what the progress bar should
show?

Hi all and thanks for the reply.

Firstly its not a problem - I found a solution it can be done using API
....that is not wrong - is it ? ;)

re: what makes you think that program2.exe knows better what the progress
bar should show?

I develop windows services that handles stuff in the company during the night.
I want to develop a program that controls the status of the services and
that can tell what they are doing.

I had in mind to add a custom service control command - "send status"

In that custom command the service will update the progressbar and / or
textbox that it will have as "progress controls" in his properties.
I will use API to update these by their hwnd...
VOILA

Guy,

I also wonder how to implement a progressbar to see an updated
position of a Windows Service using s"ervice controller" control.
Don't know which API function does show you the current service
proceeding situation within a progress bar, (also knowing it would be
good, not so criticial), reporting only "servicecontroller1.status" as
text.
