GetAccessPaths method
Description | Returns a variant array containing the strings that are legal AccessPaths for this ItemID. May be Null if there are no AccessPaths for this ItemID or the server does not support them. |
Syntax | GetAccessPaths (ItemID As String) As VariantItemID — Fully Qualified ItemID |
Remarks | AccessPath is the "how" for the server to get the data specified by the ItemID (the what). The client uses this function to identify the possible access paths for the specified ItemID. |
Example | Dim MyOPCBrowser as OPCBrowser Dim sItemID As String Dim vAccessPath As Variant Set MyOPCBrowser = MyOPCServer.CreateBrowser '/* Get item information for this branch MyOPCBrowser.ShowLeafs For i = 1 to MyOPCBrowser.Count '/* Get ItemID for selected item sItemID = MyOPCBrowser.GetiItemID(i) '/* Get Acces Paths for selected ItemID vAccessPath = MyOPCBrowser.GetAccessPaths(sItemID) Next 'i |
