Get Windows file type icon.

Sin Jeong-hun

I already found that I have to use SHGetFileInfo to get the System's
associated icon with that file. But what about I just want to get
associated icon for some specific extensions? For example, 'avi'.

Think of a P2P program. The user searched for 'avi', and the program
should show result avi files with associated icons but there's no
actual file on the users system. Maybe a workaround is to create a dumb
(0KB) temp.avi file somewhere on the users system, and then apply
SHGetFileInfo. I know that would work but looks crappy. Please teach me
a decent method. Thank you.

Demetri,

This won't work because it will not allow the caller to get the icon for
a particular extension without having a file which has that extension.

Jeong-hun,

From the documentation for SHGetFileInfo:

If the uFlags parameter includes the SHGFI_USEFILEAT TRIBUTES flag, this
parameter does not have to be a valid file name. The function will proceed
as if the file exists with the specified name and with the file attributes
passed in the dwFileAttribute s parameter. This allows you to obtain
information about a file type by passing just the extension for pszPath and
passing FILE_ATTRIBUTE_ NORMAL in dwFileAttribute s.

So basically, pass "*.avi" to the function, along with
FILE_ATTRIBUTE_ NORMAL for the dwFileAttribute s parameter, and it will look
up the icon for an avi file.

Hope this helps.

My bad, I thought he was talking about a file he already has.

Check if a Windows service running

What would be a good way to check programmatically whether a service was running? We have a service that dies periodically and I need to check to see if this service is running. I know how to check to see if the status is in stopped or running mode. But that doesn't tell me if it is actually running. I need to know this so that if it happens I can programmatically start the same service on another machine.
