Stand-alone Sync Dirs tool crash

[ND]

I just got a crash in the stand-alone Sync Dirs tool:

Exception EAccessViolation in module totalcmd.exe at 000442FE.
Access violation at address 0044552A. Read of address 01AA40B4.

I had compared two folders with many files (~4k directories), found about 100 differences, had already performed some operations (deleted some files on one side) and the crash occured while scrolling (immediately after a mouse wheel down, which is why I think it may be related to scrolling).

WinXP SP2, TC 7.5pb6, English, portable

It has only happened this one time (i.e. the problem is not reproducible), but I thought the addresses from the error message may help in tracking down the problem.

Thanks for your report. Unfortunately the address doesn't help me much. It's in function TWinControl.GetHandle, so it seems that Windows tries to get a Window handle for a control which no longer exists. I will try to turn on stack traces in the standalone sync tool the next beta, maybe that helps to find the error.

I am not alone! Same Mousewheel down error.
Topics should be merged.

Edit:
Didnt you add support for stack traces in the last beta? Whats the difference?

BTW I just checked with Process explorer what dlls are loaded by the different syncs (TC intern and standalone)
The following dlls are NOT loaded in standalone sync:

Code: Select all

ATL.dll	
iertutil.dll
mscms.dll
NETAPI32.dll
ntshrui.dll
urlmon.dll
USERENV.dll

There is something about a mousehandle in "iertutil.dll"

[ghisler(Author)]

The next beta will contain a better stack trace function which may help me find the problem.

2ghisler(Author):
Did you really improve error output in last beta (pb7)?
You announced it in last post, but I didn't find a line in "history.txt".

Also I got this error on mouse-wheel down:

Code: Select all

Application Error
---------------------------
Exception EAccessViolation in module TOTALCMD.EXE at 001FF58C.

2ND:
What Mouse do you have?
I got a "Logitech MX 518".

[Samuel]

Perhaps I got a way to reproduce the problem:

1) I just compared 2 folders
2) press F3 on a png file (lister starts - but doesnt show the image - see here)
3) close lister
4) use mouse wheel down

Perhaps the 2 instances of TC (lister & sync) interfere each other.

I got a similar (short) error like above and I got:

Code: Select all

Total Commander 7.50PB7 pre1

BTW: Why is there a "pre1" in the title of the bugreport?

Edit: In my tests "2" could be call of lister on any file.

I had tried to reproduce (following the steps mentioned above) and it was looking OK until I decided to close Sync dialogue:

Code: Select all

---------------------------
Application Error
---------------------------
Exception EAccessViolation in module TOTALCMD.exe at 00044452.
Access violation at address 0044567E. Read of address 00DC4090.
---------------------------
OK   
---------------------------

Trying with clean ini:

Code: Select all

---------------------------
Application Error
---------------------------
Exception EAccessViolation in module TOTALCMD.EXE at 001FF58C.
Access violation at address 006007B8. Read of address FFFFFF88.
---------------------------
OK   
---------------------------

As mentioned few posts above: it happens only if mouse wheel has been used. On my PC error message is not shown right away. It waits for close.

Mouse: Microsoft something (I can't find a box ) but without any special driver installed.

Looks like Christian hardcoded version number.

[Samuel]

Great to hear this semi confirmation. I wondered why it was only me.

[fenix_productions]

I wondered why it was only me.

I don't remember any earlier note about lister. Without it, it's impossible to me to get any crash. There is even no difference if I use plugins or not.

[Samuel]

There is actually no earlier note about lister. I think I even got some crashes without him. But I dont know for sure.

[ghisler(Author)]

I don't remember any earlier note about lister. Without it, it's impossible to me to get any crash.

I can confirm that, thanks very much! The problem is that Lister thinks that it is loaded as a standalone viewer, because there is no Totalcmd.exe main window. Therefore it installs its own scroll wheel handler. When you then close Lister, that handler will point to nowhere because Lister is no longer there. Now it also makes sense why the stack trace didn't help - Windows tried to call my scroll wheel handler, but it was no longer there...

[Samuel]

Sounds great. This randomly appearing error just got on my nerves.

[ghisler(Author)]

If you need to use lister to view a file, keep it open until you close sync to avoid this error. If you use multiple listers, keep the last opened until you close sync.

[Samuel]

Confirmed.
I hope you mean as a workaround
Looking forward to the next beta.

[ghisler(Author)]

Yes, of course I mean it as a workaround!
