Constant Crashes

[admin]

pretty steep learning curve... that's what I thought, and I got pretty far without this tool the last years ... but good to know it's there.

Help me with my english, please.
Doesn't "steep learning curve" mean, that after a short time you know quite a lot?

And: I have no experience with PCs in this matter. But from my time with programming I must say, I don't know what I had done without dump analysis. As in a dump you can see a problem, without you just have to guess. (And I had dumps of 50 cm height on paper, no guessing here.)

OK - I'm often amazed about your quality of guessing. But sorry: for some kinds of complex errors, especially if you cannot reproduce, only much luck or a dump will help you.

I don't think you can compare VB to the tools from your time. VB works on a different level of abstraction. I don't doubt that dumps can help when you know how to make the translation. But I don't and currently my interest in learning it is smaller than my interest in some other nice things.

"Steep learning curve" doesn't mean the time to learn is short - it means it's initially very difficult, but once you get the initial learning over with learning the subsequent stuff generally goes easier.

Given that English is often imprecise, that different people may have different meanings for idioms, and that I could certainly be using it wrong (someone correct me if that's the case), I'll just go ahead and make clear that this is what I meant in any case when I used the phrase.

Steep - I had to look this up in a dictionary
Had a second look: still would say it means "to go up very fast" or so?

But whatever: you mean *slow* start - and then I understand Don a bit more trying to avoid it.
And I think he's right: if VB doesn't help him, for example by mapping VB-Statements to offsets in DLL or so, and by locating VB-variables in the dump, he might have limited advantage.

Okay, I only had one crash last night, while using my jpeg catalog software. Left the computer on all day today with XY open and both Firefox and IE open as well. No crashes. It seems to only happen when I'm actually doing something, and XY is in the background. It's never crashed WHILE I was using it; it's always in the background, while I'm doing something else. And so far it seems to happen with video/images. I'll try uninstalling/reinstalling (again), and maybe try turning off the preview function in XY, see if that makes any difference.

For what it's worth, the problem is NOT with my anti-virus. I had a friend who uses the same AV as I do try XY, and he has had no problems.

Thanks for making that clear. This is the kind of thinking that helps me more than minidumps.

I tried to read a dump anyway. What i did was to
1. use the procdump utility from sysinternal's tools suite to create a full dump when xyplorer crashes.
2. Then i used xyplorer nearly 20 minutes until it crashed and voila: i had a dump on Windows 7.
3. Then i downloaded the debugging tools from Microsoft and installed it (see http://support.microsoft.com/kb/315263).
4. Afterwards i started the WinDbg tool, loaded the dump file and let it analyze.

This is the result:

That reads for me as if the method vbaStrToAnsi fails with an illegal argument. Makes this sense?

Ok, cool!, but I never call vbaStrToAnsi directly. And string conversions to ANSI happen in a million places all the time. Which reminds me to a user here (who was here only short time and never came back) who was able to tell me in which procedure and even roughly in which line the error happened! He talked a bit about how he did it but I cannot find the postings. Maybe about 1 year ago...

[ogroeger]

I think that would only be possible when you provide a pdb file (compile with /debug:pdbonly).

I did not do anything. There was probably some degree of reengineerung involved.

Please find DisableSHChangeNotifyRegister in the INI and set it to 1:

Still crashes?

I also d/l the debugging tools a day or so ago. Problem is, I don't know how to create a crash dump, and don't really know how to read them, but if someone can give me some reasonably specific instructions on how to create the dump, I'll gladly send it to anyone who thinks he or she can make sense of it.

Yep, for you (and anybody else with "constant crashes").

But note that certain things (e.g. Undo) will not work anymore with this setting.
