PRODUCT : ObjectVision NUMBER : 631
VERSION : 1.0
OS : WIN
DATE : September 11, 1991 PAGE : 1/1
TITLE : Spawn a DOS or Windows executable from ObjectVision
ObjectVision has the ability to spawn any DOS or Windows
executable (with the .EXE extension) file. This can be used to
run Paradox, Quattro Pro, or any other executable file.
The way this is done is by playing a little trick on a DDE link.
Create a button field called SPAWN. Now use the tree tool to
include a DDE function to work with this button. The easiest way
to explain how to do this is with an example. Suppose you want
to load the file SAMPLE.WQ1 into Quattro Pro. These files are in
the directory C:\QPRO. You would create a DDE link with the
@DDEOPEN command like this:
@DDEOPEN("SPAWN","C:\QPRO\Q","C:\QPRO\SAMPLE.WQ1","","")
This will start Quattro Pro and load the SAMPLE.WQ1 spreadsheet.
It is important not to include the file name extension after the
executable file, and the executable file must have the .EXE
extension.
