how programatically actual screen size (width , height) in windows phone? use following: how screen size on windows phone 7 series but panorama control bit tricky, since above code gives panoramaitem width , height ( not panorama width , height). i have following code creates popup: modalpopup = new popup(); modalpopup.child = new modalwait() { maxwidth = application.current.host.content.actualwidth }; modalpopup.isopen = true; as result popup created width of panoramaitem, not total width of phone screen. there's right margin not covered popup. see screenshot below: any ideas how overcome right margin , actual phone screen size? the maxwidth property not set element's width. gets/sets maximum width constraint of element. want use width property instead. the code showed application.current.host.content.actualwidth give correct screen width, not panorama item's width.

i have case, generate instance dynamically ie, have map map<string,class> classmap=new hashmap<string,class>(); classmap.put("key1",panel.class); classmap.put("key2",panel1.class); classmap.put("key3",panel2.class); class clazz=map.get("key"); gwt.create(clazz); when compile using gwt compile got exception compile -strict or -loglevel set trace or debug see errors. [error] errors in 'com/asklepian/web/sample/sample.java' [error] line 19: class literals may used arguments gwt.create() is there better way achieve same.thanks in advance retrieving class objects done adding lowercase ".class" classname. maybe change map classmap.put("key1",panel.class); classmap.put("key2",panel1.class); classmap.put("key3",panel2.class); , try recompile that.

when go resource view -> myproject.rc -> version -> vs_version_info i've got fields can change. possible change these fields through cpp file? use like: #define filedescription "this program" that cool because it's annoying go there , change these fields. you can't. version resource embedded exe linker, isn't variable. windows knows how find , display version in properties window. trying modify code isn't useful design, isn't running when user looks @ properties. nor can modify own exe file, locked while program running. , uac stops programs tinkering executables, iceberg sinks roman's approach. you don't have use resource editor if annoys you, .rc file text file can edit text editor, .cpp source code. , preprocessor gets shot @ file first, can substitute strings editing .h file .rc file #includes gets job done too.

i using nodejs express. return custom 404 not found error page. have working. have not found solution of how return error code res.render(). saw few similar questions old , using deprecated methods. appreciated. check these: app.use(function(req, res) { res.status(404); url = req.url; res.render('404.jade', {title: '404: file not found', url: url }); }); // handle 500 app.use(function(error, req, res, next) { res.status(500); url = req.url; res.render('500.jade', {title:'500: internal server error', error: error, url: url}); });

i trying port haskell code f# , getting strange error don't know how around. have discriminated union function defined below: type othertype = othertype1 of string | othertype2 of string type mytype<'a> = mysub1 of datetime * string * (float -> mytype<'a>) | mysub2 of 'a | mysub3 of datetime * string * (bool -> mytype<'a>) later have function works on type such let fun1 date mytype (myfun2: ('b -> mytype<'a>)) = match mytype | othertype1(string1) -> mysub1(date, string1, myfun2) | othertype2(string1) -> mysub3(date, string1, myfun2) this constrains myfun2 type (float -> mytype<'a>). there way prevent happening , keep k generic? the result second pattern match falls. thank you. update: looking @ haskell code trying replicate think issue in haskell version othertype gadt , othertype1 becomes othertype double , othertype2 becomes othertype bool. myfun2 able...

lets have function want user able select appropriate texture in type safe manner. instead of using glenum of gl_texturex define method follows. void activate_enable_bind(uint32_t texture_num) { const uint32_t max_textures = gl_max_combined_texture_image_units - gl_texture0; const uint32_t actual_texture = (gl_texture0 + texture_num); if (texture_num > max_textures) { throw std::runtime_error("error: texture::activate_enable_bind()"); } glactivetexture(actual_texture); glenable(target_type); glbindtexture(target_type, texture_id_); } is guaranteed work under implementations based on opengl specification, or implementers allowed have `gl_texture0 - gl_texture(gl_max_combined_texture_image_units -1)` defined in non-contiguous manner? i modifying code aswell here in have: void activate_enable_bind(uint32_t texture_num = 0) { glint max_textures = 0; glgetintegerv(gl_max_combined_texture_image_units, &max_textures); if (static_cas...

i transferring image python backend c++ backend. chose google protobuf, following simple structure: message data { optional string image = 1; } i use python read image , put image field: data = server_pb2.data() data.image = (open(image_fn).read()) but protobuf complains following message: value error: [hex data] has type str, isn't in 7-bit ascii encoding. non-ascii strings must converted unicode objects before being added. i have tried several ways make data unicode without success. maybe has encountered problem before? or there better way transfer image data? thanks! you should using bytes type in .proto file rather string . bytes used arbitrary sequence of bytes (eg image). string used sequence of utf-8 or ascii characters (eg text).
