问题 I have a custom action inside an MSI installer that makes some changes to some configuration file. my requirement is to run the installation in silent mode so I am using msiexec. Here is the command: msiexec /i myInstaller.msi /l* out.txt myContextParameter=value1 myContextParameter is never passed to the custom action so when I do context.Parameters["myContextParameter"] I get a null value. When I run my MSI in UI mode the parameter is passed correctly. I also made sure the name of the

问题 I'm absolute beginner in web technologies. I know that my question is very simple, but I don't know how to do it. For example I have a function: function addNumbers($firstNumber, $secondNumber) { echo $firstNumber + $secondNumber; } And I have a form: <form action="" method="post"> <p>1-st number: <input type="text" name="number1" /></p> <p>2-nd number: <input type="text" name="number2" /></p> <p><input type="submit"/></p> How can I input variables on my text fields and call my function by

问题 I have this authentication check in my global.asax file in the Session_OnStart() call: if (Session["Authenticated"] == null) { Response.Redirect("~/Login.aspx"); } This kind of session authentication is tightly coupled in all our web apps so I have to use it this way. This global.asax sits in an older Webforms project, which my MVC project is sitting in. So for this reason I believe its letting me access my controller action e.g http://localhost/controller/action directly without my session

问题 Shouldn't this work? If I had a break point on the last } it stops there but it never gets to the Contact Action, and the page after being posted it's just a blank page with no source code what am I missing ? Thank you. 回答1: Your Contact(ContactModel model) should not be "void", instead it should be public ActionResult Contact(ContactModel model) { //.... some code return RedirectToAction("Contact"); } 来源： https://stackoverflow.com/questions/4137775/redirecttoaction-is-not-redirecting

问题 I'm trying to write a custom action to run off of an admin grid that I have built. Is it possible to send a value from a column in the grid to the controller via either get or post? I've tried googling, but I cannot find a proper explanation for this anywhere. A link to an explanation of the column settings ('getter', 'type' etc.) would also be useful if this is available. 回答1: Add this code to your Grid.php: $this->addColumn('action', array( 'header' => Mage::helper('yourmodulename')->__(

问题 I'm in a trouble managing a spinner, so may I ask for your help ? I have a spinner with its adapter. I initialize the spinner with a list of values when starting my activity. Then I force the selected value to be the one used in the object that I manage. Once the screen is initialized : When the user selects a value in the spinner, according to the selected value, I may continue (or not) to another activity for let the user choose a complementary and necessary value. If the user "cancels"

问题 I've seen a post earlier that recommends favoring Actions over listeners. I am not so familiar with the ActionMap. What are the disadvantages of the each approach? I like to make inner classes that implement listeners. Is that a bad practice? Thanks 回答1: Key bindings rely on actions. There is a potential risk that Action "implementations tend to be more expensive in terms of storage than a typical ActionListener ." In practice, the problem does not arise. Here is an example. Using KeyListener

问题 I have a receiver class listening on several actions but it can not catch the android.intent.action.BOOT_COMPLETED action. What I am doing wrong? here is my manifest file: <uses-sdk android:minSdkVersion="7" /> <uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED" /> <!--<receiver android:name=".OtherReceiver"> <intent-filter> <action android:name="android.intent.action.BOOT_COMPLETED" /> </intent-filter> </receiver>--> <receiver android:name="com.myApp.AppReceiver"

问题 When I follow the instructions at How do I add an action or outlet to a class in Xcode 4.3.1?, or Apple's First iOS App tutorial, there's no option for Action. There is only options for Outlet and Outlet Connections. What am I doing wrong? 回答1: You can connect actions only to subclasses of UIControl . You are trying to create an action from a UIView , which is not a subclass of UIControl and does not have actions. Start the drag from the button, and not the "main view" 来源： https:/

问题 I'm quite new to WP. Task is to develop a plugin for oauth authentication on one of not popular openID providers. I did the same for CodeIgniter project, but WP is a CMS and is little bit complex for me to understand. In Codeigniter i check authorisation before each action. In WP i need a hook which uses for it... before each page printing, or maybe.. it would be right to say before each action in terms of frameworks. What is this hook's name? 回答1: A list of all available hooks can be found
