Capture Mode 

 

 

 

Single Shot 

N/A 

The LBA-PC stops after collecting one frame.  

Property values will not change until the LBA-

PC receives another Start command. 

Continuous 

FALSE 

The LBA-PC will continuously update property 

values.  By the time a VI can read property 

values after the OnNewFrame event, the values 

have changed.  Use this configuration if you do 
not care which frame the properties relate to. 

Continuous 

TRUE 

The LBA-PC will set property values that 

correspond to the same frame of data.  These 

values will remain until you reset NewFrame to 
FALSE. 

 

OnNewFrame.vi contains an example of reading property values after receiving an OnNewFrame 

event.  All example VIs are packaged in LbapcActiveX.llb, which can be found in the 

“ActiveX\Examples\LabVIEW” directory under the LBA-PC installation directory. 
In Visual Basic you can read any desired properties during this event.  All properties correspond 

to the same frame of data.  After return from this event property values will change. 

 

9.3.3.2 OnOperationComplete 

This event fires when Ultracal is finished or the LBA-PC is stopped because Statistics Frames or 

Time has expired.  This event passes an integer bit flag as a parameter.  This bit flag is identical 

to the OperationComplete property and is defined as follows. 
Ultracal complete 

0x0001 

Auto Exposure complete 0x0002 
In LabVIEW, the parameter data is part of the Event Data cluster output from the Wait On 

ActiveX Event VI.  Unbundle the Event Data, index the ParamData array, and convert the result 

using the ‘Variant To Data’ VI.  Ultracal.vi contains an example of calling the Ultracal method and 

responding to the OnOperationComplete event.  Example VI’s are packaged in LbapcActiveX.llb, 

which can be found in the “ActiveX\Examples\LabVIEW” directory under the LBA-PC installation 
directory. 

 

ActiveX is based on Component Object Model (COM) technology.  DCOM, Distributed COM, extends 

COM to support communication among objects on different computers—on a local area network (LAN), 

a wide area network (WAN), or even the Internet.   
The LBA-PC ActiveX server supports DCOM.  The LBA-PC ActiveX server always runs on the LBA-PC 

computer and can easily be configured for local or remote access.  Properties, methods, and events are 

the same as described above, whether local or remote.

Local access is always the default.  When LBA-PC is installed, the LBA-PC ActiveX server is automatically 

registered for local access.
