U++ program whose filename has Chinese word leaves logs after exit [message #23223] Thu, 01 October 2009 04:22 Go to next message

Hello.
I built a program with U++ and rename it with filename which has Chinese word.
After the program exits I found some log files left.
In the log files I knew that it's because U++ library can't remove it successfully.
I try to find the reason why it happens and I found the problem is that it fails to call DeleteFileW function.
This is the screen shot of OllyDBG. In the parameter of DeleteFileW the Chinese words become a series of "?".
index.php?t=getfile&id=1942&private=0
I though it's a bug. Would you please have a look at it?

And then, even if I knew the log files help to find bugs.
Is there anyway I can disable this feature of U++?
Because sometimes the operation of creating new files and deleting files is not expected.

Thanks.

Regards,
LeiMing

What is in the .log? What is the filename of the these logs?

Normally, .log is not created in non-debug mode. Are you in compiling in Optimal?

Well, normally, .log is not created in debug mode either, unless you have some LOGs or DUMPs or something in your code. But sometimes some debug logs in u++ are forgotten (a bug).

Ah, I can see it is usrlog.

Well, encoding problem aside (have to look into it), this one should not be created unless you call

ActivateUsrLog()

somewhere...

I have never heard of that function and I think I have not used that function.
the source code of that package has only some 60 lines of code.
I have upload it here. build it and rename the exe file to "̹.exe" then run it. click the X up-right directly and then some files come out.

but if I keep the filename no Chinese word, the log files will not come out.

Hope I have thrown light on it.

Regards,
LeiMing

edit:
now I also upload the exe and logs.
please feel free to delete it to save space after usage.

You're welcome.
Thanks for your work.
Then I'll delete the attachment of exe and log to save forum's space.
