Jianjun,
The easiest way is to record a macro. Load the EPIX XCAP software, 
load IPP then start recording a macro, drop down Acquire / 
video/image and click on snap. Stop the macro recording. The 
Shutter control must be "on" and the Mode must be "trigger" on the 
control unit.

In my case I got this:
ret = IpAcqSnap(ACQ_NEW)

I enhanced it a bit and used in VB6 code to automatically acquire 
and save the image when the appropriate time and temperature (!) 
was reached on a hot stage:

      If PreviewFlg = True Then                    'Should be set 
when live image is being displayed
         ret = IpAcqShow(ACQ_LIVE, 0)       'Stops the live image
     End If

     ret = IpAcqSnap(ACQ_NEW)           'Snaps a new image and 
displays it in a new image window
     ret = IpWsSaveAs(FileName, "TIF")  'Saves image as tif under 
value stored in variable FileName

     If PreviewFlg = True Then
         ret = IpAcqShow(ACQ_LIVE, 1)       'Restarts the live 
image if it was running before
     End If

Hope this helps,
Jay
