I create own errorsys procedure which may prevent for use open database or generally for terminate sleeping program process (in pocket memory in some situation exists only program process without any window and database may still open). When error handler is call program show error: "Too many recursive error handler calls". How to fix this ?
Thanks for reply

Sample code:
- Code: Select all Expand view RUN
#Include 'FwCe.Ch'
Function TestErr ()
Local oWnd := Nil
AppIni ()
Define Window oWnd Title 'Test error'
@ 100, 100 Button 'Open1' Size 60, 20 Pixel Action OpenTest ()
@ 130, 100 Button 'Open2' Size 60, 20 Pixel Action OpenTest ()
Activate Window oWnd
DbCloseAll ()
Return .T.
Function OpenTest ()
Local aStr := {}
If !File ('TESTERR.DBF')
AAdd (aStr, {'F1', 'C', 10, 0})
DbCreate ('TESTERR', aStr)
Use TestErr New
Else
Use TestErr New
Endif
MsgInfo ('Database in use')
Return .T.

Static Function ShowError (oError)
Local cError := ''
Local n := 2
Local nHn := 0
If oError : GenCode == EG_OPEN // this generates error "Too many recursive error handler calls"

PostQuitMessage (0)
Quit
Endif
cError := oError : Description
If !Empty (oError : Operation)
cError += Hb_OsNewLine () + oError : Operation
Endif
cError += Hb_OsNewLine () + 'Call history:' + Hb_OsNewLine ()
Do While !Empty (ProcName (n))

If !File ('Error.Txt')

FWrite (nHn, cError)
FWrite (nHn, Replicate ('-', 40) + Hb_OsNewLine ())
