Hi Support,

We think we've found a bug in the Window_update@ routine when trying to close 2 or more child windows in SF8.3. Our sample code works fine in SF8.1 but not SF8.3. Are you able to investigate and confirm please?

We provide further details below and the sample code to reproduce the problem.

Sample application:

In Clearwin, the program generates a format window containing 3 child windows side-by-side (with vertical scroll bar) and another pivoted child window at the bottom.

The issue:

The application hangs without closing just after or at Window_update@ line when running in Windows 7. If we're running Windows 10, the application crashes instead of hanging, generating two Werfault messages . In Windows 10, the event viewer shows the failure occurring in the SF 8.3 Salfibc.dll. However, if we run the same compiled executable but using SF 8.1 Salflibc.dll it successful completes without any errors.

We subsequently ran some further tests with different combinations of clearwin windows. The application worked fine in SF8.3 if there was only one child window but failed if two or more child windows were used. SF8.1 worked with all combinations.

If you need any more information, please let us know.

Many thanks

Ian

[I've had to attach the code as separate post to fit in the space available]

Your program fails at runtime for me when compiling for 64 bits.
It runs OK but with a delay when terminating for 32 bits.

I have now identified and fixed a related bug in ClearWin+ but I don't know why this did show in earlier releases. Your program now runs correctly for me and there is no delay when terminating for 32 bits.

Let me know how urgently you need a update. An intermediate beta release is probably due anyway.

Thanks for the speedy reply. We are only using 32bit executables at present. The delay we encountered was around 5-10 seconds for each of the two WerFaults in Windows 10. Are you running with Windows 10?

We would be grateful for an immediate update as we're planning a major release in mid-July and we wish to run some tests over the next couple of weeks. In terms of the next full release (SF 8.40?), do you have an indication of the timeframes?

Thanks

Ian

I will see what I can do for an intermediate beta release of the DLLs.
I don't have any information about a date for the next full release.

In the light of my problems trying to run the beta279 demo program I 'randomly' picked out Ian's program for additional testing (I'd copied it but not actually run it previously under beta169).

For me under beta 279 it compiles and links fine (no errors) but when I run it it procedes to populate the windows with the dta but then *booo-um* the progrm just closes down automatically.

This occurs after for 32 bit and 64 bit, same behaviour.

I'm on Windows 7

Paul, has any progress been made yet on the MDI interface problems (on this post and the other one - the strange behaviours when reducing individual child windows to tabs then recovering, etc ....) or is it still in your pending tray awaiting an opportunity for analysis ? (behinf %pl clean-up of course Wink lol)
I know you've introduced the other interesting addition (the dynamic tabs feaature in the recent bet release) but you can't be going to abandon the basic MDI option no ?

I have looked at this and fixed it to the extent that it is now OK in the tests that I have run. The fixes are in the latest download.
