winapi - How to port the C++ SetWindowsHookEx to C# or is this not possible? -

-

i looking @ example in microsoft kb318804 use threadid of "current" application!!! have c++ code works have rewrite it, , prefer re-write in c# while in there. 1 thing threadid of target application so:

uint lastid = getwindowthreadprocessid(targethandle, intptr.zero);

no, getcurrentthread not correct call getting thread id of remote application today , want do. targethandle handle remote application.

i cast lastid int , tried wire c# code setwindowshookex returns 0 , fails. appdomain.getcurrentthreadid() seems work (even though deprecated, replacement though doesn't work either).

do have go c++ code then? or there way work in c#?

currently register hookhandler in c++ other application , events back.

have checked out pinvoke.net entry setwindowshookex?

if setwindowshookex returns null, supposed call getlasterror, in c# should call marshal.getlastwin32error (assuming dllimportattribute.setlasterror included on p/invoke signature.)

from pinvoke.net:

signature

[dllimport("user32.dll", setlasterror = true)] static extern intptr setwindowshookex(hooktype hooktype, hookproc lpfn, intptr hmod, uint dwthreadid);

calling

intptr hhook;  using (process process = process.getcurrentprocess()) using (processmodule module = process.mainmodule) {     intptr hmodule = getmodulehandle(module.modulename);      hhook = setwindowshookex(hooktype.wh_keyboard_ll, hook, hmodule, 0); }

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...
