Thank you all for your quick responses! I followed David Crow's advice and it worked. Thank you again for the support. This is definitely the best message board I ever came across!

Hi.
I want to enumerate all of the processes that are running on a particular desktop. Enumerating all processes isnt the problem, its the filtering of them that is causing me trouble.
The desktop a process is to run on is specified in the STARTINFO passed to CreateProcess, however, as far as I can see, this is the only place where the desktop is specified, and the only function I can find to retrieve this information is GetStartupInfo, which will only return the STARTUPINFO structure for the calling process.
Any ideas?

So what exactly is your question? If you are not wanting all of the processes that CreateToolhelp32Snapshot() provides a list of, what are you wanting to filter on?

The desktop they are a part of. One of the memebers of STARTINFO is lpDesktop. If you create a desktop called CP, using CreateDesktop, then set lpDesktop to "CP", when using CreateProcess, the process runs in the CP desktop, so, if your not viewing the CP desktop, you wouldnt see the applications window appear (if it has one).
What I can get, is handles to all of the windows in running on the desktop - maybe I can use that to find the processes, and kill them.

I've got a service.
On rare occasions, it crashes. When it does, it needs to restart.
Here's the details:
(1) it is configured in service-control to restart if failure.
(2) we don't want to rely on DrWatson or any external program to monitor it.
(3) we've tried using SetServiceStatus to signal error on shutdown.
How do we programmatically signal to the service control manager that this failed and it just needs to restart. We've had some problems where 'crash ui' get's invoked.

Peter,
Since no body is providing any direct answers I will ask a few questions.
How do you now it crashes? Does it log errors or what?
Could you define “crash”? If your service terminates abnormally then how can you signal anything since your “shutdown” routine will not be executed.
I am not familiar with the term “crash ui” what is it?
Ultimately I suggest you find the problem and fix it rather than counting on restart.

Ultimately I'd like to fix all crashes. But if something bad does happen the service needs to log what happened and restart.
A crash is a crash -- and sometimes it's an assertion. We can detect the crash and write out a minidump. But getting the service control manager to allow us to restart is the problem.
As for "crash ui" -- on a machine with no installed debugger, a message box comes up saying that you did something bad (read attemtped at 0x000000....)
MSDN support had no good answer, except they recommended to write a "service monitor" program to accomplish what the SCM won't do.
oh well.

Hi guys
Somebody has an example about to reduce the minimum size of a ComboBox
When I add a Combo box,there is a minimum size and I'd like to have one smaller (I talk about height) than this.
Do you know a derived class where I could see how to do this?
Best Regards
Doc

You can adjust the height within the resource editor. If you click on the down arrow portion it outlines the minimum size.

You might want to try SetItemHeight for the combo.

i want to draw into a windows menu but i
can't find a way to get a device context
for it. more specificially, i want to
make a rectangular menu of icons. windows
doesn't seem to support rectangular menus,
so instead i am making a menu with 1 owner
drawn item. i draw the menu when i get the
WM_DRAWITEM message. i can select the
correct option because i can call
GetCursor() when processing WM_MENUSELECT.
what i can't do is update the highlighting
while the mouse moves. i can process
WM_EVENTIDLE messages, but when handling
this message i have no way of drawing into
the menu. WM_DRAWITEM provides a DC, so I
know one exists in the system. Is there
any way to copy this DC and use it later,
or get the DC? Are menus implemented as
windows? Because if so i could maybe
get the hWnd for the menu or something.
Thanks, Phil.

I am studying the communication of MS Media Player while it plays a http file. I find a interesting thing.
I wrote a small program to accept requests from the media player. For most video files like mpeg, I found that it sends http get request to download a the video file. But, the I tried to use the media player to play a wmv or asf file, it did not send any request, it however tried to receive the information from the server instead of sending a request. As result, the server program of course can not provide any wmv/asf file for downloading by media player.
I don't understand why media plyer doest not send an http request while downloading wmv or asf files. What possible inside operation does it perform?
Could you give me some tips?
|
|
|
|
|
Does anybody know?
Why does the web client begin to receive information from the server before sending a request? In what case they will do that?

I am currently using the Pdh to enumerate through processes running on the system in order to get the process id of a particular application.
Given that I know its name is there a simpler way to achieve this?
Thanks

Here are a couple of options:

Thankyou David

Okay, so WMI seems pretty neat, until you figure out what it takes to get it installed if it is not already on a system. Just a word of warning before running off to depend upon it.

Thanks I will bear this in mind

I wrote a resource script with menu resources duplicated on several languages.
MSDN states that I can control loading appropriate version of resource using
SetThreadLocale() call, but this way doesn't work. Operating system always
loads English version of menus in spite of what thread locale I'm using. Can
you tell me what's wrong? I'm working with Windows XP SP1.

What value does it return?

SetThreadLocale() return TRUE. I'm feed in it LCID equal to
MAKELCID(MAKELANGID(LANG_RUSSIAN, SUBLANG_DEFAULT), SORT_DEFAULT),
but it resources loaded in English. Dont know why?

Here is an example which should load russian version of menu, but it will display window with english menu. Why?
