You can use service routines to get service/device status, see MSDN for
more details or
try the following code. I took it from my program, if something is
missing, please let me
know, I'll send you the rest of the code
void CProjlistView::OnGetstatus()
{
try
{
UpdateData(TRUE);
SC_HANDLE hSCManager =
OpenSCManager(m_ComputerName,NULL,SC_MANAGER_ENUMERATE_SERVICE);
if(hSCManager==0)DispLastError();
SC_HANDLE h = OpenService(hSCManager, m_ServiceName,
SERVICE_ALL_ACCESS);
if(h==0)DispLastError();
SERVICE_STATUS Status;
E(QueryServiceStatus( h, &Status ));
char buf[256];
DWORD len=256;
E(GetServiceDisplayName( hSCManager, m_ServiceName, buf,
&len));
buf[len]=0;
CString Name= buf;
PrepareLine(Name,Status);
m_ServiceStatus = Name;
CloseServiceHandle(h);
CloseServiceHandle(hSCManager);
UpdateData(FALSE);
}
catch(...)
{
if(m_TimerID)
{
KillTimer(m_TimerID);
m_TimerID=0;
}
}
}
CString CProjlistView::PrepareLine(CString &Text, SERVICE_STATUS &
Status)
{
CString S;
switch(Status.dwCurrentState)
{
case SERVICE_STOPPED: //Stopped
S="Stopped ";
break;
case SERVICE_RUNNING: //Running
S="Running ";
break;

}

return Text;
}
void CProjlistView::E(BOOL val)

Subject: Detect devices on NT?
Hi, can anyone tell me how to detect (or name of functions
to do so) whether or not a particular driver on running on NT?
(ie the drivers that appear in the Control panel | Devices list
after you install them)
Thanks in advance

Subject: Re: SQL Server for VC++
What do you mean by 'cannot see it' ? It should be on the list of the
running services (Control Panel/Services).
If you start ISQL_w, press 'server list' button. Your local connection
should be there. Give more details, if you still have a problem

Subject: SQL Server for VC++
This may be a little off list.
Can anyone tell me where to find instructions for installing SQL Server
on a single PC (NT Workstation). I want to start writing programs
around SQL Server. To do this I want to be able to work on a single
PC. When I install SQL Server now I have trouble getting it right.
Like I can't see my server which should be my PC. I have a few books
but they don't cover this type of install.
Any help appreciated.
TIA, Doug

EMAIL MARKETING WORKS!!
Bull's Eye Gold is the PREMIER email address collection tool.
This program allows you to develop TARGETED lists of email
addresses. Doctors, florists, MLM, biz opp,...you can collect
anything...you are only limited by your imagination! You can
even collect email addresses for specific states, cities, and
even countries! All you need is your web browser and this program.
Our software utilizes the latest in search technology called
"spidering". By simply feeding the spider program a starting
website it will collect for hours. The spider will go from website
to targeted website providing you with thousands upon thousands of
fresh TARGETED email addresses. When you are done collecting, the
spider removes duplicates and saves the email list in a ready to
send format. No longer is it necessary to send millions of ads to
get a handful of responses...SEND LESS...EARN MORE!!!
A terrific aspect of the Bull's Eye software is that there is
no difficult set up involved and no special technical mumbo-jumbo
to learn. All you need to know is how to search for your targeted
market in one of the many search engines and let the spider do the
rest! Not familiar with the search engines? No problem, we provide
you with a list of all the top search engines. Just surf to the
location of a search engine on your browser then search for the
market you wish to reach...it's that easy!
For instance if you were looking for email addresses of Doctors
in New York all you would do is:
1) Do a search using your favorite search engine by typing in
the words doctor(s) and New York
2) Copy the URL (one or more)...that's the stuff after the
http://... for instance it might look like
http://www.yahoo.com/?doctor(s)/?New+York
3) Press the START button
THAT's IT!!! The Bull's Eye spider will go to all the websites
that are linked, automatically extracting the email addresses
you want.
The spider is passive too! That means you can let it run all
day or all night while you are working on important things or
just having fun on your computer. There is no need to keep a
constant watch on it, just feed it your target market and give
it praise when it delivers thousands of email addresses at
the end of the day!
Features of the Bull's Eye Software:
* Does TARGETED searches of websites collecting the email
addresses you want!
* Collects Email addresses by City, State, even specific
Countries
* Runs Automatically...simply enter the Starting information,
press The Start Button, and it does the rest
* Filters out duplicates
* Keeps track of URLs already visited
* Can run 24 hours per day, 7 days per week
* Fast and Easy List Management
* Also has built in filtering options...you can put in words
that it "Must" have while searching,...you can even put in
criteria that it "Must NOT Have"...giving you added flexibility
* Also imports email addresses from any kind of files (text
files, binary files, database files)
* List editor handles Multiple files to work on many lists
simultaneously
* Has a Black-Book feature... avoid sending emails to people
who do not want to receive it
* Built-in Mail program...send email directly on the internet
with just a click of your mouse
* Personalized Emails...if the email address has the user's
name when it is collected,..you can send Personalized emails!!!
* Sort by Location, Server, User Name, Contact Name
* Advanced Operations:
=B7 Email address lists export in many different formats
(HTML, Comma delimited, text file)
=B7 Advanced editing...Transfer, Copy, Addition, Delete, Crop,
Move to Top/Bottom
=B7 Operations between lists...Union, Subtraction, Comparison
* Program is Passive,...meaning you can run other programs at
the same time

Hi everyone:
When I use dbgrid in vc++, I can get the Column Object by
Dbgrid.getColumns(index) method, But how can I get the Columns object from
dbgrid? Just like VB, when you want to add a Column, the code is :
Dbgrid.Colums.add. What about the VC++ 5.0
Thanks a lot .
