From memory there is a limit of 255 characters in the string in a DDEExecute
call from Excel VBA.

This is sort of backed up by this

I know that's a bit woolly, but it was a long time ago. Good luck

I'm using DDEExecute to send some MapBasic commands to MapInfo

cheating a bit) from Excel VBA. For the most part it works flawlessly.
I'm pretty happy.

However, I have some very long MapBasic commands that don't seem to be
sent completely.

For examle, the MapBasic command "Create Cartographic Legend" only
works if I have a small number of items for the legend. If the string
is very long the entire command does not get sent or does not execute.

Has anyone else ever had this problem with sending very long strings to
MapInfo Pro from Excel VBA using DDEExecute? Or to any other programs
for that matter?

Is there a string length limit?

Thanks in advance.
