Event Queue is a tag that corresponds to an internal list of events received.
|
 |
If Return cleared data is FALSE, the event data from the Event Queue is removed. Otherwise, it is returned in Cleared Data.
|
 |
error in describes error conditions that occur before this VI or function runs.
The default is no error. If an error occurred before this VI or function runs, the VI or function passes the error in value to error out. This VI or function runs normally only if no error occurs before this VI or function runs. If an error occurs while this VI or function runs, it runs normally and sets its own error status in error out. Use the Simple Error Handler or General Error Handler VIs to display the description of the error code. Use error in and error out to check errors and to specify execution order by wiring error out from one node to error in of the next node.
 |
status is TRUE (X) if an error occurred before this VI or function ran or FALSE (checkmark) to indicate a warning or that no error occurred before this VI or function ran. The default is FALSE.
|
 |
code is the error or warning code. The default is 0.
If status is TRUE, code is a non-zero error code. If status is FALSE, code is 0 or a warning code.
|
 |
source describes the origin of the error or warning and is, in most cases, the name of the VI or function that produced the error or warning. The default is an empty string.

Event Queue is a returned tag that corresponds to an internal list of events received.
|
 |
Cleared Data is an array of Event Data, which is a cluster that describes a set of values obtained from an event.
 |
Event Name is the name of the event associated with this cluster.
|
 |
Event ID is the ActiveX dispid of the event associated with this cluster.
|
 |
Param Names and ParamData are paired. Each corresponding value in the arrays identifies the name and value of the parameters of the event.

ParamData and Param Names are paired. Each corresponding value in the arrays identifies the name and value of the parameters of the event.
To access ParamData on a panel or diagram, use the Variant To Data function to convert the individual elements of the Variant into the desired data type.

|
 |
error out contains error information. If error in indicates that an error occurred before this VI or function ran, error out contains the same error information. Otherwise, it describes the error status that this VI or function produces.
Right-click the error out indicator on the front panel and select Explain Error from the shortcut menu for more information about the error.
 |
status is TRUE (X) if an error occurred or FALSE (checkmark) to indicate a warning or that no error occurred.
|
 |
code is the error or warning code.
If status is TRUE, code is a non-zero error code. If status is FALSE, code is 0 or a warning code.
