Cheat Engine

[Twizz]

I'm sorry if this has been posed before, but I wouldn't know what to search, and there are alot of threads with misleading titles.

Anyways, when I search for something, it can be any type, and the search returns no addresses found, sometimes I accidentally click next scan again. But it doesn't work, I mean it really screws around with my whole computer. Some programs stopped responding, I couldn't click on anything, Cheat engine wasn't responding, and it took a good 2 minutes for it to terminate the scan and during that time, I coulnd't do anything but wait.

I just tried it again and the same thing happened. Is this a known bug?

If You scan in a big process and You have given a not too efficient search criteria (like searching for 0 or unknown then unchanged value), then the scan will take some time and it will slow down Your computer. And You may also run out of free space if You do not have at least a few GB on Your HDD.

Well, its not that I scan with an ineffiecient search criteria, because even when I do search like that it doesn't take this long. I have 100GB+ free on my HDDs, so I'm good there. I really think its a bug.

Like I said, I'll search for an Array of Bytes, or a DWORD or something, if no results are found, and then I click "Next Scan", it locks up my whole computer for a while.

I didn't experience anything like this with XP. I guess it would be useful to post some basic info about Your OP system and PC config.

I have 4 GB Ram
Core 2 duo e8400
And I am using 32-bit Windows 7

it also depends on harddisk speed. E.g if you use a slow usb disk as a temp folder, you'll be waiting a lot

define "No results found" Do you mean you get the text "Found: 0" Or do you mean you get a "Found: #" with something else than 0, but en empty list ?

anyhow, try creating a new folder at c:\ e.g "c:\cetemp" and make sure that folder has write and modify access for the administrators group
then go to settings->scan settings and set the scanfolder to "c:\cetemp\" (and restart ce to apply the changes)

locking only happens when you had a huge amount of results and you click next too soon (after a scan has finished the results are written to disk as a low priority. When you click next scan it checks if that writing has finished, and if not, increase the priority and wait for it to finish)

I have a SATA drive. I tried what you suggested with the cetemp folder and it didn't work.

When I say no results, I mean that I see the text "Found: 0" above the results list.

Have you tried doing what I'm doing? Maybe its just me. Anyways here's what I do, I open a relatively small program like firefox in CE, then I do a 4 byte search for a number that will return 0 results, something random like 6729645, then I click search. It returns with 0 results after less than a second. Then I press "Next Scan" with the same random number I used for the first scan, and everything goes wacky. Can you try it and see what happens? If it only happens to me, then its no biggie, and I can just remember not to press scan again after a 0 reult scan. Cause this problem never happens during normal use, or even non-normal use like scanning for an unknown value, than an unchanged value. That takes about 10 seconds. This is quite different, but it can be avoided.

Oh, now I get it. Yes it is happening for me too but I never experienced it as there was no reason to click on next scan after 0 results. Though the problem is not so severe to me. It will use the CPU on 100% and slow down the comp but it will not "lock" the system and I can abort the scan or just use the task manager to close CE.

found and fixed it (svn rev 700)
(stopentry:=totaladdresses-1; and stopentry is an unsigned integer)

Thanks guys
