Example

This VB example initializes a combo box with camera names and uses it to switch between the cameras:

Private Sub Form_Load()
CamLst = ActiveGige1.GetCameraList
For i = 0 To UBound(CamLst)
Combo1.AddItem (CamLst(i))
Next
Combo1.ListIndex = 0
ActiveGige1.Acquire = True
End Sub

Private Sub Combo1_Click()
ActiveGige1.Camera = Combo1.ListIndex
End Sub


Remarks

The value of the property is a zero-based index into the list of GigE Vision™ cameras discovered on the network. The list of camera names can be retrieved with GetCameraList. If you use the property window of your development environment or ActiveGige's property pages, the Camera property field will be presented as a list box containing the indexes and names of all the connected cameras.
