VSFlexGrid 8.0 works with any 32-bit version of Visual Basic. Ideally, however, you should use it with VB5 or later.
When used with VB4, the optional parameters in some properties are not interpreted as optional by VB. The most important property affected by this is the Cell property, which has the following syntax:
[v =] fg.Cell(iProp, [Row1], [Col1], [Row2], [Col2])
In VB5 or VB6, you may omit all or some of the last four parameters. In VB4, you must supply all five.
