Wow, didn't you even think of going to class?

This makes no sense whatsoever. Not the assignment, that's easy, but rather asking for such elementary help outside of class. I realize it's been a few decades since I was in school, but surely things haven't changed that much for a teacher to make an assignment without having first gone over the subject matter. If your "squat level" is so low as you put it, why are you even in the class? Are your classmates having equal difficulty?

Hi,
I am creating a windows service in VC++.Net. Is it possible to give comman line parametes when we are installing the windows service ?
Ex : WinServ.exe -Install -D "Display_name" -P "Path"
Once we created the service can we install this in any machine(older OS) or .net is a must ?
Thanks and Regards,
Venkat

If you are actually using .NET (i.e. managed code), then the .NET runtime must be installed. (Though I think writing services in managed code is a bad idea.) If written in native code, assuming you use only APIs from the older OS, they will run there as well.
Services can accept command line arguments.

Thanks for the Information.
Could you please give any example of Windows service written in native code ?
Thanks and Regards,
Venkat.

Two reasons:
Performance and resource bloat.
While some .NET code can, in fact, run faster than native code, my extensive testing has found that this is mostly in UI code; in non-UI code, this is rarely the case and I've found .NET code typically runs about 30-50% slower (after JIT.) While some services do nothing the vast majority of the time, many are required to periodically do small things as fast as possible. In this, well crafted native code is best. (Yes, I said well crafted; well crafted .NET code is very probably better than crappy native code, but that goes without saying for just about any software.)
Resource bloat is another problem; even "small" .NET applications take up lots of memory and resources. Among other things, this causes slow boots and long shutdowns. If an application or service is truly idle for a long time, and other things are happening on the system, odds are it's memory will eventually get paged out. With .NET, the amound of demand paging when the appliation or service becomes active again is quite significant. (This is one thing that really irritates me with the ATI Catalyst Control Center.)
Do recognize that many serverices have two component; the memory resident component, which should be lean and mean, and a management console or something comparable which is launched on demand. Using .NET for the latter may make perfect sense (though I've honestly yet to see someone actually do it efficiently on the client for a commercial product.)

Thank you for the excellent reply!
With so many choices in frameworks, languages, SDKs, etc., I'm constantly having to make decisions
on which way to go based on performance, ease of use, extensibility, longevity, etc. and it's
nice to add others' real-life experience and opinion to the "equation".
Had you answered "Because I heard it's slow" I would have screamed.
Thanks again,
Mark

my code:
CComQIPtr<IHTMLDOMNode> pRootNode(lpParentDisp);
CComPtr<IDispatch> spChildren;
if(FAILED(pRootNode->get_childNodes(&spChildren)))return;
CComQIPtr<IHTMLDOMChildrenCollection> pChildColl(spChildren);
long lCount = 0;
pChildColl->get_length(&lCount);
for (long l = 0;l<lCount;l++)
{
CComPtr<IDispatch> spChild;
pChildColl->item(l,&spChild);
CComQIPtr<IHTMLDOMNode> pChild(spChild);
CComQIPtr<IHTMLElement> pElement(pChild); // I don't obtain the point
}
please somebody help me ! thanks........

im making a simple wav audio player. i need a volume control (i.e. slider) which is independent from the windows main vol ctrl - that is, modifying the volume in the audio player should not affect the windows volume settings. i am using playsound(). please point me in the right direction. thanks.

Controlling volume by process is only available in Vista.
