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



Hello David,

 

Thank you very much for the hints.

 

You are absolutely right. I observed the clipboards during the simulation all the time (by open the clipboard viewer), the things that I saw is just the inputs and outputs between TRNSYS and EES all the time………… until……….. when the error came. The data on the clipboard suddenly changes to the  unrecognized characters ;-{

 

[1]                      À


DataObjectÀxOle Private Data´µx*Áÿÿÿÿ

 

Could it be possible that during the simulation, if other programs which also use the function of clipboard activates, then data in the clipboard becomes something else which is not number character? But I am quite sure that only trnsys and ees that were opened during simulation.

 

 

In the EES side, I switch off the display warning message function but I could not find the place for switching off the error message. From the source code, I guess that EES is called in a minimized mode anyway.

 

I tried to run the program in a short specific time close to the time that error happened, but there was no error. The error comes only when the program had started for some thousands hours in advanced. I guess that the problem might come from the specific results but I still can not find it. I will try to debug for a short while, If I can’t I will arrange the files and send it to you. Thank you very much for your kindly help.

 

Kind regards,

Wimolsiri

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
  



I am running a model type 66 (Calling external program-EES) under Trnsys16. After the program has been run about 2500 hr (smoothly), 2 error messages show up:

A Win32 API function failed.

And

An illegal character was encountered in position 1 of the string delP while reading CLIPBOARD.

The last message indicates that there is something wrong in the data in the clipboard. Firstly, I thought that there should be something wrong with the setting of the numerical format, but it is right.

Where is the temporary file in the clipboard saved? Is there any possibility to check the data in the clipboard?

What does the first message mean (a win32 API function failed)?
