I'm investigating some nasty crashes I'm having with 7.06 with procmon and I noticed some error messages in the log when switching windows.

However I don't think this is related, as 6.35 generates the same error messages. Also don't know if i may cause any problems for users.

Code:
Path: HKLM\SOFTWARE\Microsoft\CTF\KnownClasses
Result: NAME NOT FOUND


When talking in a channel and the log file is upated:

Code:
Operation: WriteFile
Result: FAST IO DISALLOWED
Path: C:\Users\xx\AppData\Roaming\mIRC\logs\#test.xxx.log


OS Windows 7

Does this happen with a clean install of mIRC? Are you able to reproduce the issue using a specific set of steps? Listing error results from procmon is not that helpful I am afraid - it is quite normal for events to return error values, "name not found" values or other combinations of succesful or not succesful results from calls to functions. Also note that mIRC has no idea what "HKLM\SOFTWARE\Microsoft\CTF\KnownClasses" is and does not access that registry key itself, so it is likely that one the system DLLs is doing so on behalf of mIRC. mIRC, like all other applications, uses system DLLs which perform all kinds of functions that mIRC has no control over.

This is really nasty, it seems to be random.
I can't reproduce it.
The crashes occur starting from 7.0x.

Are there any way for me to provide you with exact debugging information?

In the meantime I'll try to reproduce with a clean mIRC.

I would need to know a step by step method of reproducing the issue in order to track it down I'm afraid. Please remember that you should only test with the latest beta since all previous betas have known issues.

Yes, I always use the latest beta smile
Ok, as soon as I can reproduce it I'll let you know.

Looking at your screenshots, you are using a folder name for mIRC that looks like it's a script name. Are you experiencing this problem on a clean copy of the beta without any scripts loaded? Or only when you have scripts loaded? And if you're using a MTF theme, does it happen without that theme loaded?

I'm experiencing this problem with my own script, yes.
The problem is, it seems very random.

Additional debugging info:

You still didn't answer the only important question here, can you make it crash with a clean install of mirc 7.07 ?

Still trying, but so far no luck.
My current suspicison is mdx.dll.
Time to upgrade the remaining dialogs to dcx I guess.

That would have been a very important piece of information to start with. We already know that MDX doesn't work well in 7.x.

You're right, I had hoped the debugging information would be enough for Khaled to locate the problem wink

Unfortunately, MDX is not the problem.
Now disabled DCX as well. Have to run it for a couple of days before I know if it doesn't crash anymore.
6.35 doesn't have this problem.

DLLs will need to be updated. Even DCX probably does, but you should have no problems downloading a current version of DCX that will work, whereas MDX doesn't have any new versions. Also, just as a note on MDX, it will work depending on what parts of it you use. I have one old script that I made that uses MDX (before I found out about DCX and switched) and it works fine. I don't know which parts of the DLL don't work... you'd have to test each feature to find out what part(s) don't work in mIRC 7.

Also, fixes for DLL problems isn't Khaled's job. That's up to the DLL (or script) authors. Khaled makes mIRC and does his best for compatibility, but he cannot make everything compatible while still improving mIRC as much as possible. A major change to mIRC such as Unicode support prevents maintaining compatibility with everything. That means the script and DLL authors need to make updates for compatibility. Leaving out vital information in hopes that Khaled will fix a script or DLL problem just wastes his time (and those of us on the forum who try to help) because we try to verify and find your problem on a clean copy of mIRC where it won't obviously have that problem.

Of course DLL problems are not Khaled's job.
If mIRC still crashes without any DLL loaded, there must be something in the script that causes mIRC to crash. Since it's so random, I haven't been able to reproduce it, so I used external tools to produce debugging info. I have insufficient knowledge of programming to know if this helps Khaled or not. Unfortunately it didn't, so I have to keep on trying to reproduce it in such a way others can reproduce it as well.
