txtBlock.LinkTopic = "RSLinx|testsol" | 'Assign DDE application|topic to DDE text box |
txtBlock.LinkItem = "N7:0,L5,C5" | 'Assign DDE link item to DDE text box (L5 = Length of 5, C5 = 'Format the data to go in 5 Columns via Tabs) |
txtBlock.LinkMode = 2 | 'Open DDE link (manual) |
txtBlock.LinkRequest | 'Request data from RSLinx |
