Applies to:

READDATAQFILE Active X Control

Description:

Go to the event marker on a specified channel. Works similarly to MoveTo - essentially "MoveTo" an event marker. Each file has at least 2 event markers - the beginning and the end of a file.

The first parameter is the event marker offset. A negative number moves the file pointer to the left; a positive number moves the file pointer to the right (i.e., +1 for next event marker, -1 for previous event marker).

The second parameter is the channel index (0 is the first channel, 1 is the second channel, etc.).

Syntax:

ReadDataqFile1.GoToEventMarker(Offset,Channel) (where offset is a positive integer for forward direction x number of event markers and negative integer for backward direction x number of event markers and channel is the channel index)

Variables:

Offset is long and Channel is integer.

Example:

Private Sub CloseFile_Click()

ReadDataqFile1. Close

End

End Sub

Private Sub EventMarkerLeft_Click()

'goes to previous event marker in first channel

ReadDataqFile1.GoToEventMarker -1, 0

DQChart1. Chart (ReadDataqFile1. GetData(DQChart1. Xmax, FormatBinary))

Label1.Caption = ReadDataqFile1. CurrentLocation

End Sub

Private Sub EventMarkerRight_Click()

'goes to next event marker in first channel

ReadDataqFile1.GoToEventMarker 1, 0

DQChart1. Chart (ReadDataqFile1. GetData(DQChart1. Xmax, FormatBinary))

Label1.Caption = ReadDataqFile1. CurrentLocation

End Sub

Private Sub Form_Load()

ReadDataqFile1. Open

DQChart1. Chart (ReadDataqFile1. GetData(DQChart1. Xmax, FormatBinary))

End Sub

Private Sub MoveRight_Click()

ReadDataqFile1. MoveTo DQChart1. Xmax, 1

DQChart1. Chart (ReadDataqFile1. GetData(DQChart1. Xmax, FormatBinary))

Label1.Caption = ReadDataqFile1. CurrentLocation

End Sub

Private Sub MoveLeft_Click()

ReadDataqFile1. MoveTo -DQChart1. Xmax, 1

DQChart1. Chart (ReadDataqFile1. GetData(DQChart1. Xmax, FormatBinary))

Label1.Caption = ReadDataqFile1. CurrentLocation

End Sub
