-
i creating search page , have use activity , places in gwt. have used key listener when user press enter redirect user on result page. problem when user use browser button , again press enter key listener call twice same if user again click button next time call trice , on. there solution this? you're adding listener when activity starts never remove (e.g. when activity stops). the full solution depends how code activity (do reuse activity instances? have separate view activity acting presenter/controller? if so, view singleton, or @ list lives longer activity , can reused activity instance? etc.)

java - accessing the spring context -

-
something confuses me spring. understand 1 of main functions promote modularity , loose coupling providing way modular components (classes) wired without having knowledge of other modules' implementations, contracts expose. however, in practice, find myself in following situation. one class has spring application context. let's in main(); so load spring in main, , rest of objects nicely injected beans , can interact without being tightly coupled. but if 1 of objects has method every time it's called, needs create fresh bean? object needs reference spring application context. it's no longer pojo, it's coupled spring? i guess in practice, create global object contains spring application context easy access classes need this, still seems bit messy , counter spring philosophy of loose coupling? is 1 of things? it's not perfect it's still lot better having classes tightly coupled? edit: , if use global object hold spring application context, how

c - Why can we use function pointers both as (*func_ptr)() and func_ptr() to invoke a function,but not so for array pointers? -

-
suppose have function pointer func_ptr of type void (*func_ptr)() .then know using can invoke function using pointer both : (*func_ptr)(); func_ptr(); but again, suppose have pointer integer array int (*arr_ptr)[5] , why can't refer array arr_ptr[] , , consequently elements arr_ptr[0] , arr_ptr[1] etc? why can use (*arr_ptr)[0] , (*arr_ptr)[1] ? the type of arr_ptr[0] int [5] ; type of (*arr_ptr)[0] int . if wanted to, use arr_ptr[0][0] . #include <stdio.h> int main(void) { int (*arr_ptr)[5]; int a[2][5] = {{1, 2, 3, 4, 5}, {11, 12, 13, 14, 15}}; arr_ptr = a; printf("%d %d\n", (*arr_ptr)[2], arr_ptr[1][2]); return 0; } you can see code "running" @ ideone . that function pointer can used either way ( nice ) sintactic sugar.

numpy - Zero padding multiple values in Python -

in so, solution adding single 0 between values in numpy.array : import numpy np arr = np.arange(1, 7) # array([1, 2, 3, 4, 5, 6]) np.insert(arr, slice(1, none, 2), 0) # array([1, 0, 2, 0, 3, 0, 4, 0, 5, 0, 6]) how add more zeros between each value in original array? example, 5 zeros: np.array([1, 0, 0, 0, 0, 0, 2, 0, 0, 0, 0, 0, 3, 0, 0, 0, 0, 0, 4, 0, 0, 0, 0, 0, 5, 0, 0, 0, 0, 0, 6]) you can create 2dim array, , flatten it: import numpy np = np.arange(1,7) num_zeros = 5 z = np.zeros((a.size, num_zeros)) np.append(a[:,np.newaxis], z, axis=1) array([[ 1., 0., 0., 0., 0., 0.], [ 2., 0., 0., 0., 0., 0.], [ 3., 0., 0., 0., 0., 0.], [ 4., 0., 0., 0., 0., 0.], [ 5., 0., 0., 0., 0., 0.], [ 6., 0., 0., 0., 0., 0.]]) np.append(a[:,np.newaxis], z, axis=1).flatten() array([ 1., 0., 0., 0., 0., 0., 2., 0., 0., 0., 0., 0., 3., 0., 0.

html - Showing required fields by bolding -

-
i have html form. show of fields required making them bold. in principle, should go css rather html? how it? <form action="doit" id="doit" method="post"> <label> name <input id="name" name="name" type="text" /> </label> <label> phone number <input id="phone" name="phone" type="text" /> </label> <label> year <input id="year" name="year" type="text" /> </label> </form> just of top of head, think if you're willing use html5 , use <input type="text" name="year" required> property, should able do: input:required{ font-weight:bold; } and of course, go wild here , start throwing around borders , sorts of stuff make stand out.
