Clarion 5 WinDSS app crashing 1

[mikeyb540]

Hi,

I am supporting an App called WinDSS developed in Clarion 5 with TopSpeed DBs and it runs on Win2000 Pro.
The app is constantly crashing with GPF errors.

Is there a way I can debug?
Also, are there any updated ODBC drivers for .TPS? I got a driver thats v3.00 C40TRX.DLL 2/14/2000


Txs in Advance.

Hi,

Common GPF sources are :

- String slicing (ie MYString[i:j]), it is safer to use instring etc..
- 16 bits applications
- Multithreaded Applications (specially if there if message is used a lot...)
- ANY variables not set to NULL after use.
- use of omittable parameters
- use browseFuzzyMatch template
- in a routine : EXIT out of an Accept loop instead of Break

ETC...

Finding a GPF is such a time consuming job... good luck!

Thanks Valery. You gave me a good direction.

Why is it so hard to find ODBC drivers for TPS?

hi,

There is only one provider of TPS ODBC driver, it is softvelocity and it is really expensive.
