Hello,
i wrote a printing routine that works fine on one of my PCs (WinXP
SP2).
On my second PC (winXP SP2) it runs fine when i start the EXE-file.
But in the Lazarus IDE or in GDB it raises the following error when i
try :
Printer.Printers[Printer.PrinterIndex]

Program received signal SIGSEGV, Segmentation fault.
0x67c318b9 in hpvui50!DllGetClassObject ()

Backtrace:

#6  0x72f76771 in WINSPOOL!EnumJobsW () from
C:\WINDOWS\system32\winspool.drv

I think there must be a connection with my HP DeskJet 850c printer-
driver.
When i select another printer as default, i can use
Printer.Printers[Printer.PrinterIndex]
to get the default printer.
But when i start the PrinterSetupDialog i get an error, too.
What can i do to run this application in the IDE ?
thx

What happens if you continue (F9)?

On F9 the same error occurs

But what happens if you continue *after* the eror has occurred?

Too bad. I don't know what can be done to prevent it.
