我一直在pb9+32位XP壞境下開發程式，現在想在win7 64下運行程式，發現無法連接資料庫，sqlca.sqlcode = -1，是資料庫連接代碼需要針對64位系統單獨寫嗎？或者是需要在win7 64位下配置什么環境引數？還是必須用pb9+win7 64位的開發環境才行？如果用pb9+win7 64位的開發環境，會不會遇到其他問題？
麻煩大佬們幫下忙，謝謝。
//連接資料庫
sqlca.dbms = ProfileString(ls_PBINI,"database","dbms","")
sqlca.database = ProfileString(ls_PBINI,"database","database","")
sqlca.userid = ProfileString(ls_PBINI,"database","userid","")
sqlca.dbpass = ProfileString(ls_PBINI,"database","dbpass","")
sqlca.logid = ProfileString(ls_PBINI,"database","logid","")
sqlca.logpass = ProfileString(ls_PBINI,"database","LogPassword","")
sqlca.servername = ProfileString(ls_PBINI,"database","servername","")
sqlca.dbparm = ProfileString(ls_PBINI,"database","dbparm","")
connect using sqlca;
if sqlca.sqlcode = 0 then
//
else
messagebox('sqlcode','資料庫連接失敗，錯誤代碼:' + string(sqlca.sqlcode))
return
end if
//連接資料庫
