c++ - Find offset exported function in DLL file -


in order apply hot fixes dll used 'loadlibrary' , 'getprocaddress' find base address , offset of exported function in dll. example:

// use handle base address base = loadlibrary(...);  // offset relative base offset = getprocaddress(...);

and using way:

// calculate offset in file offsetinfile = offset - base;  // apply hotfix in file patchexportedfunction(offsetinfile, "mydll.dll");

this worked fine far - have problem there dlls different in way calculated offset not match offset in file anymore.

obviously approach finding function simple have no clue i'm missing , why works of time not always.

maybe has idea?

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. :)
