save

问题 I'm building a little locally run CSS driven site map for auditing a huge intranet site. I've already coded the ability, to bring up a context menu which provides for options to make updates to the DOM of index.html. I would like to save these changes to index.html. I know JavaScript doesn't allow manipulation to the client file system, but I've also read in places that it is allowed if the JavaScript is retrieved from the local machine. Can anyone confirm this and point me in the right

问题 my project looks like this, http://s23.postimg.org/mrhuocn4b/asd.png and I already can save a textbox to xml file, using this code: private void SaveFile(object sender, RoutedEventArgs e) { SaveFileDialog saveFileDialog = new SaveFileDialog(); saveFileDialog.DefaultExt = "xml"; saveFileDialog.Filter = "XML Files (*.xml)|*.xml|All files (*.*)|*.*"; saveFileDialog.FilterIndex = 1; if (saveFileDialog.ShowDialog() == true) { using (Stream stream = saveFileDialog.OpenFile()) { StreamWriter sw =

问题 I am trying to save some files using C, with this code: sprintf(playerinput,"%s",end); sprintf(fileloc,"%s/.notend",getenv("HOME")); playerdata = fopen(fileloc, "w+"); /*create the new file*/ if (!playerdata) { printf("\n\t\t\tCould not save settings file."); return; } else { fputs(playerinput,playerdata); fclose(playerdata); } It should set playerinput to the end variable, which works on Linux, then set the file location to the homearea/.notend, then make or edit the file, and put it out. In

问题 I am new to Django and I'm trying to save data using ModelForm. Template 'Vlozit' has a ModelForm and when submitted, I want the data saved in the DB and the redirect to base.html that actually loads the data from the DB and lists the output. The problem is that all works fine but the data is not saved. Please help me find what I am missing. Thank you. Here's the model: class Customer(models.Model): Name = models.CharField(max_length=30) Description = models.CharField(max_length=150) Creation

问题 The best way to explain my problem is by a example. I have a Xml file with some elements in it. When I remove a element, I save the file again and this problem occurs: Before save <?xml version="1.0" encoding="utf-8"?> <ElementTree> <Elements1 /> <Elements2> <Element Name="TestElement" ID="4efa7cc9-a89a-429b-81f4-b00cde729f24" /> </Elements2> <Elements3 /> </ElementTree> After save <?xml version="1.0" encoding="utf-8"?> <ElementTree> <Elements1 /> <Elements2 /> <Elements3 /> </ElementTree>D=

问题 I have two generic save methods in a repository class: public void Save<T>(T entity) { _session.Save(entity); } public void Save<T>(IEnumerable<T> entities) { foreach (var item in entities) { _session.Save(item); } } However, when I use Save(collection) (which infers the type automatically), it recognizes it as a T rather than IEnumerable<T> and tries to save it using the first method. How do I write this save method(s) so that it can handle either case, without me having to explicitly

问题 I populate my combo box and the user selects one of the options. Then they close everything. At a later date the user may open the window again and it would be tedious to ask them to retype and reselect the options again so I would like to 'load' them. I've tried to use pickle, but I get an error related to Qt apparently: self.WordCardsFieldSelector = QtGui.QComboBox() #Fails when trying to do this dump pickle.dump( self.WordCardsFieldSelector, open( "save.p", "wb" ) ) TypeError: the sip

问题 I have these datasets: A <- 4, B <- 3, C <- 2 . So I put them in a list D<-list(A,B,C) and want to apply this function: s<-function(x) { t<-8 x<-as.data.frame(x*t) } lapply(D,s) when I apply the lapply function it just print them. How can I make it saving the result in the global environment instead of printing them? So the result should be A with value of 32 B with value of 24 C with value of 16. 回答1: Instead of lapply(D,s) , use: D <- lapply(D, s) names(D) <- c("A", "B", "C") list2env(D,

问题 I built a model in Tensorflow and I'm trying to convert it into a TensorFlow Estimator. Here is an example of what I have: train_op = tf.train.AdamOptimizer(learning_rate=lr).minimize(cost) saver = tf.train.Saver() init = tf.global_variables_initializer() assign_Wvh = pretrained_rsm.temporal_assignment(params['W']) with tf.Session() as sess: sess.run(init) for epoch in range(epochs): start = time.time() _ = sess.run(train_op, feed_dict={x: input}) print("%i. elapsed time: %0.2f" % (epoch,

问题 I am using C# and have a key the users enters to activate my program. I do not want the user to be able to see the key once it is entered. Do you have any recommendations for how/where to store it? 回答1: You can save the key as a seperate file. Encrypt the key and save it. So even if the user tries to tamper with it then you can deactivate the application.
