I have a strange and annoying problem. Suddenly, and I am pretty sure the code has not changed, I get an Access Violation error (GPF) at some part of my application.
I have a view (a looper) from which the user opens an element that opens the details in a window, in this case the Product window. As I try to open the element I get the GPF. But I don't get it every time. Sometimes I can open and close then window a couple of times, and then the error occurs. I tried to identify a patterns but it seems random.
As you can see in the dump below, the problem is at the Windev Open function. I tried to simplify the code that proceeds it with no luck. I tried to simplify the Open call by removing any parameters, but no luck.
I tried to catch the error at the Global Declarations of the window (which is the first code that runs, right?) but it does not get there. So the problem seems to be in the Open function itself.
When I try to open another dummy window with the same code at the same place I don't get any errors. Other places in the project that open the window also have problems. So it does seem to be a problem in the window but shouldn't I have caught the exception then?
I tried recompiling the project, tried deleting the cpl directory, tried restarting the pc. Doesn't help.
According to PC Soft it might be some memory access violation elsewhere in the code. But they ask me to create a simple project to send them. That does not help because in a new project with a new window I don't get the problem of course. I use the same technique of views and details windows all over the application.
Anybody any suggestions?
Thanks,
Sjoerd |

I forgot to copy the error information. See below. Also sometimes my own errorhandling catches the error, sometimes it's a Windev Security Mechanism popup, and sometimes even a Microsoft Visual C++ Runtime popup. But it all happens every nth time opening the window.
I also see an error code 1020. Does anybody know what that means?
WL call:
Process of 'Method openProduct' (ProductsView.openProduct), line 29, thread 0
'Open' function, syntax 0
What happened?
Unexpected system error.
If this error systematically occurs in the same conditions, contact PC SOFT Hot Line and specify:
- the error circumstances,
- a window, a project or the code lines used to replicate the problem,
- the details below.

Hi
you should search on this forum for GPF keyword. This problem has been
discussed several times and many possible causes have been described

Hi Fabrice,
I did search in the forum. But most topics about this either don't have a solution or it happened at some specific piece of code. My problem is that it seems to occur at the Open method when calling a specific window. Even with no parameters. And I cannot catch an error after the Open call in the actual window called, so apparently no code in the window gets run. And it doesn't happen in the debugger. So how to trap the problem? |

Hi
sorry, but if read the posts on the subject, you now understand that the
problem comes probably from somewhere else in your program...
I posted several times the principals causes I found in my experience,
after that, it's a question of going through the whole code and find if
any of those possible causes are used somewhere
Best regards
