windows - Catching a single step exception from VEH in x86 assembly -


i'm writing 32-bit windows assembly detect edits program.

i'm not sure why, using veh debug checked address causes crash (there nothing against debugging yet, memory edits), throwing exception_single_step in middle of checking code. i'm not using breakpoints, i'm tracing accesses.

how can "catch" without attaching own debugger? may have implemented wrongly makeshift exception handler nothing when raised (mov fs:[0], 0, even, not cause crash 1 expect).

scala - 'wrong top statement declaration' when using slick in IntelliJ -

Image
i'm porting project scala 2.9 2.10, therefore have use slick instead of scalaquery. i'm using slick 2.1.0 since supports ms access. according this tutorial , upgrade guide changed robs object class , added val robs : why error message wrong top statement declaration , how rid of it? edit: i'm new scala... according this question seems can't put val outside of methods or classes, right? code above directly in packge. right approach slick then? should move code in class or trait? according this changed val robs = tablequery[robs] to object robs extends tablequery(new robs(_)) {} . no warnings or errors anymore. :)
