strange behver of emWIN simulation

johanan · Feb 14th 2015, 9:00pm

Got a button that opens a new window which works OK in most cases, see attached pictures.
I have no idea why this error is popping up,(and I don't have any GUI-Task.c file...)

I ma probably doing something wrong with sending WM messages , but have no idea,
Thanks
Johanan

Hello Johanan,

Could you please provide me with a small example application which shows the problem? Thank you in advance.

Best regards,

Hello Johanan,

Thank you for your e-mail. Another question: Have you already tried to call the function GUITASK_SetMaxTask()?

Best regards,
Adrian

No, I am not familiar with this function. Note that GUI runs in one task only, so it should look to the GUI lib as a single task program.

Hello,

GUI_Task.c:
No Context available for task in _GetTaskNo(). Increase number of maximum tasks!

The error message which is shown on your screenshot clearly indicates, that the number of tasks has to be increases. This should be done using the function GUITASK_SetMaxTask().

Please find the function description in the chapter "Configuration" in the emWin user manual.

Best regards,
Adrian
