The program has caused a 'Double' fault at 001B:66E9433C

Hi,

Let me just first state that I have no experience in LadWindows. I have taken over a program written for real time data acquisition. The person who originally wrote the program has now left the organisation and I am left to pick up after him. I know that an earlier version of the program was working correctly without the crashes and the changes introduce was an update to the user graphical interface. The different sections of the program has now been organised with tabbed windows and it is this which apparently causes the fault. We get the following error message:

FATAL RUN-TIME ERROR:   "xxxx.c", line 581, col 3, thread id 0x00000350:   The program has caused a 'Double' fault at 001B:66E9433C.

This happens in different parts of the program without apparent connection. Any input where to look would be gratefully appreciated.

There was a thread on this topic a few weeks ago, here. Might give you some ideas.

Hi,

Thanks for the tip. I have disabled the icm32.dll as indicated as one of the solutions and it resolved the issue. However, the second solution to enable "Use Windows Visual Styles for Controls". From what I can see this has been enabled during the developement of the program or at least it is enabled in the current enviroment. Is there any way to check the code for non "Windows Visual Styles for Controls", i.e. what is the difference in the code between these options.

Hi Again,

Just out of coincidence I was out on the net searching for information on icm32.dll. I then noticed some had solved a similar problem by coping the dll to the application directory. I then tried to do the same, i.e. I made a copy of the dll in the project directory. The funny thing is that it worked. I thought I share this solution with you. However, I do not have an explanation for why it should work. If someone can shade some light I would be very interested.
