I am migrating a 32-bit Access project to 64-bit Access. I am replacing all the older 32-bit iGrid 6.5 objects with the new 64-bit iGrid 7.5.

I am getting an "application-defined or object-defined error" error that I tracked down to the BackColor property.

I was getting this error all morning and now the error is gone. I have no idea what changed but it is working now.

If you can ever reproduce this problem in a new database, send it to us for the further consideration.

It is happening again.
  Testing.zip (23kb) downloaded 2 time(s).

It works ok on my pc.

Can you try to reproduce the problem on other computers and if possible, in different versions of Microsoft Office?

Yes, I can find another computer to test on. But all our computers use the same (latest) version of M365. Would you be interested in a remote session to see the problem?

The error number is not always the same. Despite the error, it does set the BackColor to the light blue.

I assume you saw the single line of code in the form's Load event. If I comment out that line, the error goes away.

Do we need to run the form many times until the error appears?

Strange. Today it happened 2 times right after opening the database. Just 2 first times, and then no problems. Note that I closed/re-opened Microsoft Access every time.

A very strange issue. To report this problem to Wayne Phillips, the developer of twinBASIC (the tool we used to compile the modern edition of iGrid OCX), we need a sample that allows us to reproduce the issue in a stable manner.

I tested on several computers today and they are all getting the error.

I have no idea why it works sometimes and not other times and so I cannot think of how to create a sample where it always errors.

Well, I will pass this bug report to Wayne. Perhaps, he will eventually find the root of this problem and fix it. Иut no one can give you a more or less precise time when it will happen.

Have you ever experienced the same problem with another property of iGrid? I tried to replicate it with ForeColor but couldn't.

And what is also strange, the iGrid.BackColor property works fine in VBA UserForms. Most likely, it is a specific issue that occurs only in Access.

BackColor is the only property that has given me an error.

I don't know what you mean when you say it works in VBA UserForms but not in Access forms. Those two things are the same in my mind. Did you mean VB user forms?

I realize you have no control over how quickly this gets resolved. I appreciate whatever you can do.

Thank you, Igor.

VBA UserForms is what you can use in Word/Excel VBA to create dialogs for the user. This form package completely is completely different from MS Access forms.
