Need to integrate ImageRight and Jwalk.  I assume that you can do a DDE call to IR similar to the way you would open Word or Excel, but cannot find any information for it.  I have the VB call for most of the issues.   I need to check to see if IR is open, if not, then open it, or if already open, then proceed on to my other calls.

On a side note, how do you find that name to insert into the DDE statement (ie. msword, excel) so that I could see what name I should use for ImageRight.

I have never heard of either product, but I can tell you this:

Many, if not most, software products *do NOT* support a DDE interface -- it takes additional programming to support DDE and it is an obsolete technology.  Most products that need to, for instance, be able to open a second document as specified by an external source (e.g., Windows Explorer or a Command Line) just accept command-line arguments.  

A more sophisticated approach taken by some designers is to support an Automation object -- in which your external program can create an instance of the app and pull "its strings" to get it to perform various activities.

What I suggest is that you carefully read the documentation for the two programs, and/or search the tech support part of their websites.  If nothing pops, you can send email to the companies and ask for full technical documentation -- be sure to say that you want "API access" and describe your needs in full.

BTW, many programs will tell you their "command-line parameters" -- you can find it either in the on-line documentation (though it may be well hidden) or by using a command-line like:

    SomeApp.Exe -help
or
    SomeApp.Exe /?
or
    SomeApp.Exe -?
