Question

"The Parameter is Incorrect" error

Asked by: WeeStinker

This is a strange one. The error "The Parameter Is Incorrect" periodically and irregularly appears whenever a specific form is shown in my app. The error is definitely not sql related. The form itself is pretty busy, i.e. contains a lot of controls but I have created busier forms so I doubt if this is an issue (?).

It appears for no reason and does not cause any problem apart from the annoyance factor.  I cannot get the error to re-occur on demand. Searching the web doesn't yield much although there is some suggestion that this may be a resource issue.

I will personally send a Xmas card to anyone who can solve this (!) as well as gratefully handing out the obligatory 500 pts.

Thanks.

Try to reproduce it and explain us when it occurs. Everything else is like hitting the air.

Thanks for all the comments, I have split the points.

I have installed medExcept and hopefully this will track down the problem. I have been working on other things since I posted this and may not get a chance to get back to it for a few more days, hence the point split and answer acceptance just to keep EE tidy !
