Entity Framework, one-to-many, several columns -

-

if have main table, lets orders, , sub table of items , items table has fields item number has nullable (optional) field color applied items. how update items table, @ same time orders table, using entity framework?

here code example of have far. 2 problems, i'm entering 1 of items and, research indicates, can't add field items table?

    foreach (guid c in allitems)     { items.orderitemid = guid.newguid();       itemsorderid = order.orderid;       items.itemid = c;       if (itemid = itemthatletsyouchoseacolorid)       {           items.itemcolorid = colorid;       } else {           items.itemcolorid = null;       }      }      context.orders.addobject(orders);      context.items.addobject(items);      context.savechanges();

my orders table gets record inserted, , items gets 1 record inserted. i'm missing basic here, i'm afraid. btw, entity framework 4.0, which. believe, not require use of entitykey.

you're adding object items collection 1 time after scope of foreach.

have tested like:

foreach (guid c in allitems) {     var item = new item();      item.orderitemid = guid.newguid();     item.orderid = order.orderid;     item.itemid = c;     if (itemid = itemthatletsyouchoseacolorid)     {         item.itemcolorid = colorid;     }     else     {         item.itemcolorid = null;     }      context.items.addobject(items); }  context.orders.addobject(order); context.savechanges();

and i'm not sure understand mean

i can't add field items table

you should more precise expect. insert row, add column in table...? "field"?

how copy observablecollection item observablecollection without reference of first collection? here observablecollection item value changes affecting both collections. code private observablecollection<ratemodel> _allmetalrate = new observablecollection<ratemodel>(); private observablecollection<ratemodel> _metalrateondate = new observablecollection<ratemodel>(); public observablecollection<ratemodel> allmetalrate { { return this._allmetalrate; } set { this._allmetalrate = value; notifypropertychanged("metalrate"); } } public observablecollection<ratemodel> metalrateondate { { return this._metalrateondate; } set { this._metalrateondate = value; notifypropertychanged("metalrateondate"); } } foreach (var item in metalrateondate) allmetalrate.add(item); what causing , how can solve it? you need clone object referenced item before it's a...

All overlapping substrings matching a java regex -

-
is there api method returns (possibly overlapping) substrings match regular expression? for example, have text string: string t = 04/31 412-555-1235; , , have pattern: pattern p = new pattern("\\d\\d+"); matches strings of 2 or more characters. the matches are: 04, 31, 412, 555, 1235. how overlapping matches? i want code return: 04, 31, 41, 412, 12, 55, 555, 55, 12, 123, 1235, 23, 235, 35. theoretically should possible -- there obvious o(n^2) algorithm enumerates , checks substrings against pattern. edit rather enumerating substrings, safer use region(int start, int end) method in matcher . checking pattern against separate, extracted substring might change result of match (e.g. if there non-capturing group or word boundary check @ start/end of pattern). edit 2 actually, it's unclear whether region() expect zero-width matches. specification vague, , experiments yield disappointing results. for example: string line = "xx90xx"; strin...
