i have custom imagebutton , want custom imagebutton clickable. of surrounding area of button "clickable" , initiates new activity. want minimize "clickable background" space. how can it? <imagebutton android:id="@+id/start_button" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_alignparentleft="true" android:layout_alignparenttop="true" android:background="@null" android:src="@drawable/flashcardbutton" /> well giving shot api found imagebutton has method signature public void oninitializeaccessibilitynodeinfo(accessibilitynodeinfo info) and accessibilitynodeinfo class has method public void setboundsinscreen (rect bounds) so said think should achieve trying do, in adition @sushil answer should make work.

currently, $mymodel->getdictionary(); returns: what looking this: "7gct5yatvuxbmy2" => "leadership", "7nrxzepqczmshqm" => "...", "..." => "...", ... the way have managed is: $construct_obj = organizationalconstruct::where('is_root', 0)->where('organization_id', $this->current_company->company_id)->get(); $constructs = []; $constructs[''] = ''; ($i = 0; $i < count($construct_obj); $i++) { $constructs[$construct_obj[$i]->organizational_construct_id] = $construct_obj[$i]->construct_name; } is there easier way of getting format "key" => "speific-column-value" ? i have tried: keyby lists getdictionary map you should call pluck directly on query, don't pull down attributes models: $dictionary = organizationalconstruct::where('is_root', 0) ->where('organization_id'

i writing simple server allows sending files using http protocol. have function puts file buffer. goes before read . file size printed correctly. on read program waits. char *get_file(char *dir) { fprintf(stderr, "get file\n"); char *buff; int fd; if (fd = open(dir, o_rdonly) == -1) { fprintf(stderr, "no such file: %s\n", dir); exit(6); } size_t size = fsize(dir); fprintf(stderr, "opened file, size: %ld\n", size); buff = malloc(size); read(fd, buff, size); fprintf(stderr, "to downloaded: %s\n", buff); char *response = make_file_response(buff); return response; } you have issue statement if (fd = open(dir, o_rdonly) == -1) according operator precendence == evaluated first , thus, fd being assigned value of comparison , not opened file descriptor. with compiler warnings enabled parentheses suggested, , correted expression be if ((fd = open(dir, o_rdonly))

this question, loosely relates choose settings based on machine name asked previously, have more specific use it, hoping baked .net default. i 1 of several people in small team writing dotnet desktop , web applications. use git source repository, , becomes tiresome have change .config file connection strings each of development environments. i know there several ways overcome problem; range not storing .config files in repo in first place (and using .gitignore), through writing code parse configuration file manually adding prefixes etc suggested in other question. however, seems both overly simplistic , tedious; in production environment there may lots of legitimate reasons store multiple connection strings in config file - such having several servers - makes me think there has easier way it. so question this: is there way in dotnet .config files have multiple connection strings framework 'automatically' knows 1 load based on property, such environment or machine
