Creating a Custom Application Using Microsoft

Visual Basic

Microsoft Visual Basic is one of many applications that you can use to develop

custom OLE configuration applications for use with the SI7 I/O driver.

To start designing a Visual Basic application that accesses the SI7 I/O driver objects

[1] Start Visual Basic and select References from the Projects menu. The

Intellution SI7DRV OPC Server Toolkit 7.20 Library should display in the

Available References list box. If it does, select it. If it does not, browse your

directories for .TLB files and add SI7DRV.TLB to the Available References

list box.

[2] Select Object Browser from the View menu and select SI7DRV from the

Libraries/Projects drop-down list at the top of the browser.

[3] Select a property or method and press F1 to learn how to use it.

The type library, SI7DRV.TLB, is installed in the same path that you installed the SI7

I/O Server.

NOTE: To use Visual Basic for Applications (VBA) instead of the VB Compiler,

select References from the Tools menu in step 1 and follow steps 2 and 3 above.
