All results values will be loaded into the array all the time. Results not enabled in the LBA-PC will
be zero. Note there are three sets of Gauss Fit and Top Hat results. Either the whole beam
section, or the major and minor sections will contain valid results depending on how the LBA-PC
is configured.
9.3.2 Methods
9.3.2.1 LoadConfig
This method causes the LBA-PC to load the specified configuration file. This method takes a
single parameter that is the file name of the LBA-PC configuration file you wish to be loaded.
The file name must contain the full path and file name to the LBA-PC configuration file.
You cannot load a configuration while the LBA-PC is collecting frames, during Ultracal, or during
Auto Exposure.
Be very sure the specified file name is a valid, accessible LBA-PC configuration file. There are
many reasons why the LoadConfig may fail, most of which cause the LBA-PC to display a
message on screen. If LBA-PC displays a message, this method will not return until you respond
to the message.
Reasons LoadConfig may fail and LBA-PC display an error message:
• The file does not exist
• The file does not contain a valid LBA-PC configuration
This method returns the following:
-1 The LBA-PC is not available
0 OK
1
LBA-PC is collecting frames of data
2 File path name is too long
3 Load configuration error
9.3.2.2 Open
This method initiates communication between the LBA-PC ActiveX control and LBA-PC. You must
call this method, or the OpenIndex method, before calling any other method or accessing any of
the properties. If you do not call this method, then all the properties will be zero, methods will
have no effect, and no events will fire.
The first caller to Open will connect to the first available LBA-PC application, the next callers will
connect to the second LBA-PC, etc.
If you want to specify the LBA-PC application, then use the AppInfo property and call the
OpenIndex method.
