windows - Decimal separator and CComVariant -


can specify decimal separator used / used ccomvariant ?

context: msmxml (ixmldomelementptr.getattribute) returns ccomvariant initialized vt_bstr regardless attribute type. therefore end decimal values stored in bstr '.' decimal separator. when windows configured coma ',' decimal separator, ccomvariant unable make conversion double or float.

example:

ccomvariant dummy = "1.2345"; dummy.changetype(vt_r8); if(dummy.vt != vt_r8) {     cout << "failed convert" << endl; }  else {     cout << dummy.dblval << endl; }

when windows' decimal separator coma, fall in "failed convert". tried set std::locale::global(std::locale("english_united states.1252")) nothing changed.

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. :)
