I received the dreaded C00005 (how many zeroes I cant remember) error yesterday. And since this site is monitored by Microsoft (hope they are listening) I will detail how I got that error message. I have been happily working on my project for several months now and doing the same things everyday that I normally do, except for yesterday. Toward the end of the day I was getting eye strain real bad and was having trouble reading the small print in the properties window. When I noticed that a rightmouse click in the properties window bar has the option to go from small font to medium font to large font. I thought that may help me out. So I increased the font from small to medium and went back to working on the form. I needed a label and text box and custom pick list button for the form, that I know I had used before on another form. So instead of reinventing the wheel I would just copy the items from the other form to the form I am working on. Something I do 30 times a day. I opened the other form and selected the 3 objects and did a CTRL C. Went to the other form and and did the CTRL V. I closed the form I copied from and proceeded to adjust the object name for one of the object I just pasted and then it happened, my very first C000005 error.
This error caused me to have to restart foxpro, but I restarted my computer also. I went back in and did the same thing as above and the C00005 error happened again. So I restarted my computer and then went back into my project, Packed it, rebuilt it (recompile all) and left the properties window font alone and worked the rest of the afternoon without any problem.
The only thing that had been added to my computer lately was I installed the java developers kit two days prior. But was happily copying and pasting objects between the java install and when the c00005 error occurred.

Hope MS hears and others may learn or find a link to get this error resolved.

P.S. One of the other programmers here received a C000006 error the other day in his VFP and Visual Image scanning system.
