TX crashes when printer name is very long

[Unregistered]

Hello,

Using the C++ Class Library (TX-Version 9.1) causes a crash of Tx32.dll when the name of the Windows Standard Printer is very long.
This occurs typically with LAN-Printers and in a Windows-Terminal-Server (Citrix) environment.

Details:
- CTXView::OnCreate() calls SelectPrinter()

- SelectPrinter() creates a printer device string which is build in the form
"Devicename,Drivername,Output port"
The printer device string on a WTS for example looks like
"Client\P23027E0#\Kyocera FS-1750(KPDL2),winspool,Client\P23027E0#\Kyocera FS-1750(KPDL-2)"

- SelectPrinter() then calls SetDevicePrinter() with the printer device string as parameter

- SetDevicePrinter() calls SetDeviceHelper()

- SetDeviceHelper() sends the message TX_SETDEVICE to the TX-Control,
lParam contains the adress of the printer device string

If this string is longer than 79 chars, TX crashes with an access violation.


Is this an already known bug and more important, will this bug be fixed in one of the next service packs?


thanks in advance

Herbert
