[TRNSYS-users] Error message: A win32 API function failed.

[David Bradley]

Dear Wimolsiri,
   The easiest way to see the illegal character on the clipboard is to open 
a text editor (Notepad or WordPad) and perform a "paste" (CTRL-V). Usually, 
you will end up pasting whatever the illegal character was. The only 
information that should be transferred back and forth between EES and 
TRNSYS are numbers (text characters won't be interpreted correctly). I am 
not sure why you are getting the API function failed error message - I 
haven't ever run into that one. The one piece of advice I might give is to 
make sure that you have all of EES's error messaging abilities switched 
off. When EES is performing its calculations, TRNSYS sits in a waiting loop 
until EES posts something on the clipboard and alerts TRNSYS that it has 
finished. Sometimes, if EES generates an error in its calculations, TRNSYS 
doesn't find out about it and just waits indefinitely. If you can't figure 
out what is going on, please forward your TRNSYS input file and EES file to 
me and I will see if I can debug it for you.
Kind regards,
  David
