debugging - Visual Studio 2010 - Debug DLL - Debug Command using rundll32 doesn't work -

-

i have problem debugging c++ dll project in visual studio 2010. while debuging want dll loaded rundll32.exe automatically. follow these steps (like here http://msdn.microsoft.com/en-us/library/c91k1xcf.aspx):

  1. in solution explorer, select project creates dll.

  2. from view menu, choose property pages.

  3. in property pages dialog box, open configuration properties folder , select debugging category.

  4. in command box, type: "c:\windows\system32\rundll32.exe"

  5. in command arguments box type (main function executed): output.dll, main

  6. in working directory type: $(solutiondir)$(configuration)

  7. attach -> yes

after following these steps, try debug dll, error:

"unable attach. process "c:/windows/system32\rundll32.exe" not running on "my-pc", refresh process list before attempting attach."

anyone know how debug dll, without manually starting rundll32.exe command prompt , manually attaching process?

you should set:

"attach -> no"

otherwise vs not trying start new rundll32.exe process. setting attach -> yes tells vs attach existing process.

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...
