Example

This VB example initializes a combo box with the names of files hosted on the camera and displays the size of the selected file:

Private Sub Form_Load()
FileList = ActiveGige1.GetFileList
For i = 0 To UBound(FileList)
Combo1.AddItem (FileList(i))
Next
End Sub

Private Sub Combo1_Click()
FileName=Combo1.Text
Label1.Caption = ActiveGige1.GetFileSize (FileName)
End Sub


Remarks

The File Access functionality allows an application to read and write files hosted on the device. The data in those files may contain look-up tables, configuration sets, firmware, and other information.

This method lets you determine if the device hosts any files and retrieve their names.
