By virtue of the fact that the app was developed in VB 6 and the grid is Microsoft's, it is very, very likely that it is an activex control. As such you can access native properties and methods of the control even though test Complete does not expose them in the object browser. Since I am a recovering VB6 developer, I have a copy of the application code on my machine as well as the help files for the controls which we use. Perhaps if you could get a copy of the help file?
So I have a grid that is truedbgrid for example. If I want to navigate to a row, I do something like
myGridObjectName.Row = 2 where 2 is the 0 based index of the row I want to select.
Having navigated to the desired row, I can examine the contents of a cell in that row by specifying the column of the desired cell:
myGridObjectName.Columns(1).Text where 1 is the zero based index of the desired column.
I am not familiar with your specific grid. i don't even see a "Microsfot Grid" component reference available in my VB 6 IDE. I see datagrid and flexgrid... You will need to find information about your specific grid.
Please note well that by addressing these native properties and methods directly, you are bypassing any events that might fire within the application under test. I use the native properties for things like examining the contents of the grid, navigating for reading. But I use clicks and key strokes to manipulate.
