i've exported mbtile file using mbutil wasn't generating png tiles when i'm creating overlay map using openlayers. missing? could clarify question? tilemill not generating tiles correctly (is crashing? stalling? other signs of errors?), or completing mbtiles export , problem getting layer onto page? given code posted, should check see http://localhost:8888/1.0.0/firstproject/0/0/0.png (or higher-number tile if didn't render zoom level zero) present. if you've used mbutil export tiles, it's don't have 1.0.0 part of url around - necessary tms layer work. make directory called 1.0.0 , move firstproject if that's case.

i'd measure page speed of 1 of projects in terminal or html comment rendered @ bottom of page results i'm getting firebug in "network" tab. if there way available i'd automate , ability monitor nagio or that. have practice? thank you! check httpunit, htmlunit, selenium.... all of can jar , execute nagios plugin - , they're pretty high level. you use wget/ab and/or curl, they're @ grabbing monolithic pages (ie no css, etc).

hey guys, im getting little problem here. getting level 1 warning debug . so, think best solution loading every images of resource, prevent crash app doing. so, whats best way it? thanks! there several strategies reduce memory usage if you're working lots of images. warning you're getting doesn't mean main memory running out, running low on video ram. reduce image size before adding them project, both scaling them down and/or compressing image data. load images need @ particular time - avoid trying keep images in memory. load images using (uiimage)imagewithcontentsoffile: rather (uiimage)imagenamed: (the latter reads caches images immediately, former more "lazy"). be aggressive in 'release'ing images - don't wait autorelease kick in, send [image release]; simplify other aspects of code use video ram (e.g. remove layer transparency, remove views aren't visible, etc.)

i have multiple text boxes ids manual_input_1, manual_input_2, manual_input_3. want stop form submiting when enter pressed in textboxes. the code below know whole id of textbox pressing enter can box's value. e.g. manual_input_2 pressed enter, value = 1234. $('[id^="manual_input_"]').keydown(function(e) { if(e.which == 13) { e.preventdefault(); var id = ?; <--- id of textbox pressed enter var value = ?; <--- value of textbox pressed enter alert('enter pressed '+id+'\n'+ 'value = '+value; ) return false; } }); can done? examples helpful. thanks you can "id" with var id = this.id; and value with var value = this.value; the jquery event dispatch layer ensures this refers affected element when handler called.

numerous win32 methods use setlasterror indicate error. in .net use such method so: if (!somenativeboolmethod(...)) { throw new win32exception(); } or var res = somenativeintmethod(...); if (res != 0) { throw new win32exception(res); } i wondering if .net interop infrastructure can me. in case, import somenativeboolmethod , somenativeintmethod void methods. (for somenativeintmethod should optional, depending whether wish able see positive return codes or not). is possible? thanks. it sounds you're looking feature similar com interop feature whereby hresult signatures translated exception throwing methods. if i'm sorry feature doesn't exist. very due many many different ways win32 apis report failures. there no universal convention. unlike com there universal convention returning hresult. the best bet introduce helper function wraps pinvoke calls , check error code , throws appropriately.
