c# 4.0 - Open SQL Server CE database data from read only file system -

-

i use sql server ce database application. program located on dvd.

i cannot read data database on dvd, set sql connection string mode read doesn't work (i want read data db)

error:

opening database read-only requires temp path specified. [ db name = c:\users\ali\appdata\local\temp\rar$ex52.280... ]

please help!

in order open sql server ce database file (sdf) on read-only media, need add 2 additional parameters connection string

  • mode=read only
  • temp path=[path]

you follows:

connectionstring = string.format(@"data source = {0}\{1};mode = read only;temp path={2}",            databasedirectory,           databasename,            system.io.path.gettemppath());

if getting connection string app.config

see https://stackoverflow.com/a/10731515/19624

string connectionstring = configurationmanager.connectionstrings["myconnectionstring"].connectionstring; connectionstring += ";mode = read only;temp path=" + system.io.path.gettemppath());

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...
