i wrote a com dll in vc6,and wanna ref it in vc.net,but failed. another way,i try to import it into my test client app using "#import",then failed too,with the compiler error:"fatal error C1083: Cannot open type library file:'D:MyFirstSrvDll\Debug\MyFirstSrvDll.dll'"

thanks, but a new problem appears,when i call this proc in my embeded c sql,the return value is -266,which is the same problem @@trancount,i am nearly insane for this bad luck,why?

no,i assure i had not used this mode

yes,commit trans decremented by 1,but after this command ,the @@trancount is 1,not 0,the problem is what makes the strange,the @@trancount incremented by 2?
