angularjs - upload a file using angular, express and mongodb's gridfs -


i new these technologies , hence have limited knowledge on how upload file. during research, have seen ngupload , other javascript/directive based solutions. however, trying following , not sure else missing complete it.

i trying upload file after creating blog using angular-express-blog application. have following code

in view.jade

fieldset             h5 add media             form(name='theform', enctype="multipart/form-data")               .clearfix                 label document name                 .input: input(ng-model='form.docname', name='docname', type='text')               .clearfix                 label file                 .input: input(ng-model='form.file', type="file", name="file")               .actions               button(ng-click="uploadfiles('/page3files')") upload files

the controller, need return uploadfile page hence, passing in /page3files.

$scope.uploadfiles = function( path ) {         //alert("upload files clikced");         $http.post('/api/uploadfile', $scope.form).            success(function(data) {                $scope.form.docname='';                $scope.form.file='';                $location.path(path);            });     };

in express routes file

exports.uploadfile = function (req, res) {       console.log("doc name: " + req.body.docname);       console.log("file name: " + req.body.file.name);       console.log("file path: " + req.body.file.path);       res.json(true); };

unfortunately, getting exception @ req.body.file.name saying cannot read property 'name' of undefined.

any assistance appreciated.

thanks, melroy

for $http.post() able upload files need set configurations. headers : {'content-type': undefined}, transformrequest: angular.identity

you can use simple/lightweight angular-file-upload directive takes care of you. supports drag&drop, file progress , file upload non-html5 browsers fileapi flash shim.

<div ng-controller="myctrl">   <input type="file" ng-file-select="onfileselect($files)" multiple> </div>

js:

//inject angular file upload directive. angular.module('myapp', ['angularfileupload']);  var myctrl = [ '$scope', '$upload', function($scope, $upload) {   $scope.onfileselect = function($files) {     //$files: array of files selected, each file has name, size, , type.     (var = 0; < $files.length; i++) {       var $file = $files[i];       $upload.upload({         url: 'my/upload/url',         file: $file,         progress: function(e){}       }).then(function(data, status, headers, config) {         // file uploaded         console.log(data);       });      }   } }];

c++ - Correct method for redrawing a layered window -

i have window created ws_ex_layered window style. drawing onto memory bitmap using gdi+, , using updatelayeredwindow update graphical content of layered window. intend use window main window of application, require redraw frequently. seeing layered windows not receive wm_paint windows message [?] , need come appropriate method re-drawing window. optimisation not essential , it's nice have cake , eat too. therefore, in search of "correct" method use. here thoughts far: i guess it's idea render onto off-screen bitmap before bitblt ing or similar. 60 frames rendered per second should (more than?) enough (but how compare other applications' frame rates?). possible solutions: use settimer send wm_timer message on regular basis. useful because through specifying time-out value, can achieve desired frames per second, without requirement measure duration "frame" takes rendered. would cause input or other lags due frequency , speed of m...
