c# - RPM does work and i can't figure out why -


keep searching internet , can't figure out, readprocessmemory returning fine executing. output empty. lenght of array 0 well. 

using system; using system.collections.generic; using system.linq; using system.text; using system.threading.tasks; using system.runtime.interopservices; using system.diagnostics;  namespace memed {     class program     {         static void main(string[] args)         {             process proc = process.getprocessesbyname("client")[0];             byte[] buff = new byte[]{};             intptr bread;             intptr phandle = openprocess(0x0010, false, proc.id);             bool check = readprocessmemory(phandle, (intptr)0x5eff75b8, buff, 10, out bread);             if (!check)                 console.writeline("rpm fail");              console.writeline(buff.length); //always returns 0, value string "xyle"             console.writeline(encoding.unicode.getstring(buff));//always empty, tryed of encoding types check still blank result.             console.readkey();         }           [dllimport("kernel32.dll")]         public static extern intptr openprocess(int dwdesiredaccess, bool binherithandle, int dwprocessid);          [dllimport("kernel32.dll", setlasterror = true)]         static extern bool readprocessmemory(             intptr hprocess,             intptr lpbaseaddress,             [out] byte[] lpbuffer,             int dwsize,             out intptr lpnumberofbytesread);     } }

it's because buffer give fill has length of 0 since initialized empty (new byte[] {}). try giving room:

byte[] buff = new byte[1024];

change number based on how memory want read, , use length dwsize parameter:

readprocessmemory(phandle, (intptr)0x5eff75b8, buff, (uint32)buff.length, out bread);

also, make sure you've got correct permissions via this answer. you'll need run app elevated permissions.

opencv - DataType<cv::detail::deriv_type>::depth what is it used for -

i wondering why line used in lucas kanade tracker in opencv: datatype<cv::detail::deriv_type>::depth can explain me? in opencv, depth of mat refers type of data contained in mat 's data buffer. represented integer values correspond given data type. these integers commonly abstracted appropriate macro definition (e.g. uchar data represented macro cv_8u ). cv::datatype type-traits class provides method obtain corresponding integer value without having memorize macro means data type. there few cases user code needs use datatype::depth . more common datatype::type . a simple example shows 1 possible use of datatype::depth : cv::mat uchar_data = cv::mat::ones(3, 3, cv_8uc1); cv::mat float_data; uchar_data.convertto(float_data, cv::datatype<float>::depth); // ^^ equivalently replaced // cv_32f macro float_data.at<float>(0,1) += 0.5f; std::cout << float_data << std::endl;...

python 3.x - Mapping specific letters onto a list of words -

can please suggest approach write piece of codes automatically maps letter in letter_str onto dic_key (a dict key string type contains dashes match length of words in word_lst)? so, mapping occurs if letter appears in every words in list @ same position no matter how many words in list. if no letter appears @ position words in word list new_dic_key '----'. please see examples below thanks word_lst = ['ague', 'bute', 'byre', 'came', 'case', 'doze'] dic_key = '----' letters_str ='abcdefghijklmnopqrstuvwxyz' new_dic_key = '---e' if word_list = ['bute', 'byre'] new_dic_key = 'b--e' or word_list = ['drek', 'drew', 'dyes'] new_dic_key = 'd-e-' if words in word_list of same length code give want: word_list = ['drek', 'drew', 'dyes'] cols = [] in range(len(word_list[0])): cols.append([]) word in ...
