Drag and Drop
(Con't from page 5)
LPARAMETERS

this.paretn.NoDropicon
endcase
Keep in mind that oSource is "istSource", our Drag source. We change the cursor from the circle and slash (NODROPOI .CUR) to a bullseye whenever the cursor is over our drop target. Since both our targets are images and behave in the same way, this code is identical for either target.
2. The DragDrop method is what gets executed when the “drop” portion occurs. For these two targets the code is nearly identical:
For the Screen Picture object, the code reads:
and for the Printer Picture Object, the code looks like:
We’re done! Run the form and bingo, truly professional results?

Out and About
(Con't from page 3)
Just in time for the release of Windows 95, now cemented for August of this year, the Justice Department has stepped up its investigation of Microsoft
Corp.
because of concern that the software giant may use “unfair tactics” to break into online computer business. As of June 10, the
.~
department’s antitrust division gave on-line commercial companies
-
Prodigy, Compuserve, and America On-Line
-
one week to document their concerns.
This Just In IBM, as of Sunday, June
11,
1995, turned a hostile bid to take over Lotus into a friendly takeover and the largest software deal in history. Jim Manzi will remain in a vice-president’s position with IBM, while IBM retains most of his Lotus development team. I wonder if the Feds are going to take as close a look at IBM as they’re doing with Microsoft. Anyway, best of luck to them they’re going to need it.
