i have code: $temp =~ s/\#name\#/$customername/g; where replacing #name# value in $customername using regex. want append variable onto end of name . so want like: $temp =~ s/\#name . $appendvalue\#/$customername/g; so be: $temp =~ s/\#name_1\#/$customername/g; would work or there proper way handle this? test cases: hello #name# this intended #name# the pattern interpolates variables, no concatenation operator needed: $temp =~ s/#name$appendvalue#/$customername/g; you might need protect special characters in variable, though, use \q...\e : $temp =~ s/#name\q$appendvalue\e#/$customername/g; # not special in regex, no backslash needed (but doesn't hurt).

i creating custom slide template 8 picture placeholders , 4 text placeholders. idea user "fill-in" template text , images , once macro run, values of placeholders collected , added json file. ideally, 2 picture placeholders (big_screen_i , small_screen_i) , 1 text placeholder (caption_i) collected 1 json object. set repeated 4 times on same slide. here problems: 1) name of placeholder set in slide master view changes when more 1 of same template used (haven't pinpointed exact trigger). names change once image inserted placeholder. locating object name becomes unstable. 2) using .type of placeholder (picture vs text) doesn't differentiate between big_screen_i , small_screen_i. 3) tags , keys change or disappear when using template more once (because of repeated name). 4) unable group objects because not possible group placeholders. is there way identify each shape/placeholder , connect added content? note: using powerpoint 2016 .potm file thank you! ...

i trying adjust shape of object using value derived slider on screen using p5.js. the issue having outline of drawn shapes remain, giving after-trail effect. i have tried nostroke() modifier not draw shape. nofill() gives weirder, yet still incorrect, behavoir. code example: https://codepen.io/galleywest/pen/oejxyy var slider function setup() { createcanvas(600, 600) slider = createslider(0, 50, 0) } function draw() { rect(10, 10, 80, 80, slider.value()) } how can mitigate behavior? you need call background() function clear out old frames. var slider function setup() { createcanvas(600, 600) slider = createslider(0, 50, 0) } function draw() { background(255, 0, 0); //draws red background rect(10, 10, 80, 80, slider.value()) } more info can found in the reference .

i have field in database null when retrieve in cursor null. can tell cursor.isnull(1) true when cursor.getlong(1) should throw exception according documentation. retrieves 0 without , exception. ideas why? if take @ implementation of method getlong() in matrixcursor , can see following code: @override public long getlong(int column) { object value = get(column); if (value == null) return 0; if (value instanceof number) return ((number) value).longvalue(); return long.parselong(value.tostring()); } if value null, 0 returned.

i input here example 101-name-3.4 3.4 not input. it's not showing in output. how can solve this? for(i=0; i<n; ++i){ printf("enter id-name-cgpa receptively: "); scanf("%lld-%[^-]s-%f", id[i], name[i], cgpa[i]); } you need remove trailing s scanset directive in format string: scanf("%lld-%[^-]-%f", id[i], name[i], cgpa[i]); the s not part of scanset directive, , scanf() attempting, , failing, match s in input. detected if code checking return value call scanf() , practice. also, no declarations shown, if id[] declared array of long long int s, , cgpa[] declared array of float s, address operator should used: int ret_val = scanf("%lld-%[^-]s-%f", &id[i], name[i], &cgpa[i]); /* ret_val should 3 */
