As far as I am aware, Protel does not support DDE (though I might be wrong
on that one), and as such, interfacing with Protel needs to be made via
Protel-defined API procedures (which are documented in the SDK files). The
implementation of the files within the SDK "package" is such that Delphi is
required when using these (or at least as far as I am aware).
In mentioning the above, I am saying about as much as I can, given the NDA
associated with acquiring the SDK files.
It *might* be possible to use something like Windows Recorder (provided with
Windows 3.x) to "automate" an interface with Protel, or otherwise use
something like Visual Basic's "SendKey" feature, or Windows "hook" code, and
so avoid the need to use the SDK files, and hence Delphi. My understanding
is that such techniques are regarded as less than desirable for assorted
reasons. However, it is an alternative way of doing things, though IMO, not
as good a way as using SDK files with Delphi in order to implement a sounder
implementation.
