Invalid Floating Point Operation

[TonyFalla]

I have seen several references to this "Invalid Floating Point Operation" that members get at various times and wondered if it had ever been explained as to the cause.

Today I was using PTE 5.5 and had just done a preview of a project I was working on. I then went into "Open Recent Project" and got the "Invalid Floating Point Operation"message, clicked OK and then the thumbnails and the main screen went white. Tried to Open / Open Recent several times and still got the same message. Closed PTE and reopened and again Open / Open Recent "Invalid Floating Point Operation" message. I finally cleared it by starting a new Project, closing it and then opening the project I want.

There must be a reason for this message so what is causing it?

I have just had this happen again and I think I now know why it is happening. This time I even restarted my PC and couldn't clear it. Again I had opened up a project and run a preview, again when I tried to open a project I got the "Invalid Floating Point Message". After several attempts to clear I found that what I had to was create a new project then close, then open the project I had just previewed. I then saved this project, even though I had made no changes to it and then I found I could open any project I wanted without problem. Thinking back on it I think this is what I may have done originally.

It appears therefore that the problem occurs under certain circumstances when you open a project without saving the current project.

For the moment I will get round by trying to always remember to save

Tony,

I've just used PTE v5.52 and done as follows:

Opened project1

Made a small change (moved a slide along the time line)

Previewed past that slide and then ESC'd out

Opened project2 (replied No to the prompt to save project1)

Previewed through first two slides and then ESC'd out.

No problems at all!

Have I not done something that you did?

Do you still get the fault if you do what I did?

regards,

Peter

I am puzzled now because I can't reproduce the fault. I had been working on a project closed and saved it. I then opened another project and ran a preview to show my wife, didn't change anything in that project. When I tried to reopen the original project that is when I got the Floating Point error, I didn't, and should not have, receive a save message as I hadn't changed anything.

After having cleared the fault as in my second post, I have just repeated the above and it worked without error!!

I am beginning to think that this message is a catch all for any little glitch encountered.

Tony,

There are many Programs out there which do exactly what you have just experienced, they are usually 'Image Programs'.

Yes, and 'Floating point' is a 'catch-all message' and it usually means that the Program can't close because it was

waiting for a response from you. An analogy is where you are playing around with 'Open Files' and suddenly a message

appears..'There is a sharing conflict' and you say what have I done ?? ~ you haven't closed an open File, its thats simple.

Hi Brian

Thanks for that, what you say makes sense and explains why I can't reproduce the problem

Tony,

It seems that problem occurs when PicturesToExe starts with last opened particular project "A", you run Preview and then try to open another particular project "B".

Please try to remember and reproduce with these projects A and B. And if you can reproduce this situation, please send me backups of both projects in ZIP archive. I'll able find a reason of the problem and quickly fix it.

You can use mediafire.com to upload and send files

I'm afraid I have tried several times since and have not been able to reproduce the problem. I suspect however that it may be something to do with the other problem I reported that same day. The project I opened after I had run the preview was the project that I later discovered had lost some of the image files (see Template Problem started 2 Nov), but even opening the same projects I know I was running, I am unable to reproduce.

If it does occur again I will let you have the info you require

I found that this problem occurs when all slides have zero time (and 0 seconds of total duration). How it may happens I have no idea yet. So I've added checking for this situation to the code of MiniPlayer and it will prevent from appearing this error message. I'll investigate this problem to find exact reason.

What you say in your reply makes sense, the project that I did about 3 years ago, which the template had lost some of my images, was the one I was attempting to open when the Floating Point error occurred. In that I simulated what you can now do in O&A. I had a series of 15 - 20 images of the same picture which gradually got smaller. I then ran these very quickly to give a jerky movement effect. This meant that each of these slides was only on the screen for a fraction of a second, about 10ms. It still works but not as intended due to the lost images.

Do you want me to send you a copy of this project?

Tony

Yes, please send me both projects in ZIP archives. If the second project was created in old version of PicturesToExe, please pack it to ZIP archive manually (not via "Create backup in ZIP archive").
