Title: Execute vs Request :: why and how! Post by Admin on 10/31/07 at 18:41:40 [smiley=thumbsup.gif] Nicely done! & Helpful ! DDEExecute(iconn,doit) [(connection, command)] is an "Execute" statement, which does not ask for a return value. DDERequest uses 'atoms' to send data TO ecco, which are limited to 256 characters, so you use a DDEExecute which uses a shared memory string to send much larger (up to 24 or 32k depending.. on what ecco will handle) data. but Execute is not made/intended to RETURN information... other than a few bytes... so Ecco was designed to allow you a "Request" to use in conjunction with the execute... ie. Quote:
is because Execute does not *ever* send back any ecco id#, "GetLastResult" is intended to be used exactly as you have used it!, in partner with an execute command. ps: (for others) same basic structure of DDE commands to Ecco works from within Word or Excel..... |
Title: Re: Execute vs Return :: why and how! Post by pplandry on 11/01/07 at 12:34:25 I use DDERequest and have no problem retrieving large amounts of text. The trick is to use a textbox with multiline=true as the DDE link. More details avail. if required. |
