Below are 2 Dr. Watson dumps from the errors. The first is from the error that was caused by the listbox. The second is the one that occurs when closing the form. The error occurs in both Win98 and WinNT4.0 Server running SP4. These are 2 separate machines, the Watson dumps are from the NT machine. Running VFP3.0a, both systems are running totally different background software, Watson provided a list somewhere down there. Regularly, the system runs at around 3000 handles (I'm not sure what type, this is showing up by hitting CTRL-ALT-DEL to bring up the task manager and it shows up under the performance tab.). Watching the performance monitor (the separate admin tool program), the handles spike to 100 when the crash occurs. The handles in the performance monitor are processor handles (I picked handles from the processor section) and are for VFP.EXE. The error is happening when the form is closing. There is one form behind it; the form causing the error is a secondary form. I tried running just the secondary form and the error occurs, just with more effort (more moving around in the form) to cause it. The system also regularly runs around 80mb of v-mem used, and a series of these crashes runs that up to around 140 or so. I have 20 tables and 17 cursors open max in the program, almost no non-local memvars. There are about a half dozen filters set at the outset of the form. Note in first instance of the error, a cursor name, csizeavailable, shows up in the dump. I tried not ever requerying the table in the form, but the error didn't go away until I removed it from the controlsource of a listbox on the form. I put a larger table into the listbox (the table from which the cursor was selecting it's information) and it worked fine. I tried to re-create the form (copied the controls onto another form) and the error still occured (the 1st one that is). At the time of these dumps I quoted below, there were a fair number of things running, but the error does occur when nothing is open at all. I tried to run the test code for the out of handles bug and got a similar 05 error, but at a different address. Does this help?
