winforms - make autocomplete textbox using tableadapter windows forms C# -


i have piece of code autocomplete search textbox

autocompletestringcollection coll = new autocompletestringcollection();         datatablereader reader=this.customertableadapter.getdata().createdatareader();         while(reader.read()){             coll.add(reader.getstring(0));         }          search.autocompletecustomsource = coll;

is best way perform it? or there function make autocomplete source column directly?

moreover code filters first name, when use piece of code gridview gives me better search abilities catches part of name

private void search_keyup(object sender, keyeventargs e)     {         string outputinfo = "";         string[] keywords = search.text.split(' ');          foreach (string word in keywords)         {             if (outputinfo.length == 0)             {                 outputinfo = "(name '%" + word + "%')";             }             else             {                 outputinfo += " , (name '%" + word + "%')";             }         }          //applies filter dataview         myview.rowfilter = outputinfo;     }

suggestions please

this piece of code trick without using loops, fills 1 column of table in string array , used autocompletesource

            datatable dt = this.data_alldataset.merchandise;         //use linq method syntax pull title field dt string array...         string[] postsource = dt                             .asenumerable()                             .select<system.data.datarow, string>(x => x.field<string>("name"))                             .toarray();          var source = new autocompletestringcollection();         source.addrange(postsource);         cat_name.autocompletecustomsource = source;         cat_name.autocompletemode = autocompletemode.suggest;         cat_name.autocompletesource = autocompletesource.customsource;

utf 8 - split utf-8 string into bytes in python -

i trying split utf-8 string bytes in python 3. problem is, when use bytearray, byte, encode etc functions array size of element 14 bytes, not 1 byte expected. need split text file sequence of bytes , send them byte after byte using sockets. tried this: infile = open (file, "r") str = infile.read() byte_str = bytes(str, 'utf-8') print("size of byte_str",sys.getsizeof(byte_str[0])) print gives me 14, need 1... suggestion? quoting official documentation : sys.getsizeof(object[, default]) return size of object in bytes. object can type of object. built-in objects return correct results, not have hold true third-party extensions implementation specific. only memory consumption directly attributed object accounted for, not memory consumption of objects refers to. if given, default returned if object not provide means retrieve size. otherwise typeerror raised. getsizeof() calls object’s __sizeof__ method , adds
