I am doing a website on YII and PostgreSQL. It is recurrently exiting inside $model->validate() method by printing 'test'. I have searched whole code, There is no exit code on controller , model, beforeValidate(), afterValidate(), even whole project.
Question
How can i debug on such scenario. I have only access to ftp, Netbean as IDE, but no localhost. How to find which file is printing exit code or do you have any idea ?
Thank you,
Ram
Messages can be logged by calling either Yii::log or Yii::trace. The difference between these two methods is that the latter logs a message only when the application is in debug mode.
Yii::log($message, $level, $category);
Yii::trace($message, $category);
When logging a message, we need to specify its category and level. Category is a string in the format of xxx.yyy.zzz which resembles to the path alias. For example, if a message is logged in CController, we may use the category system.web.CController. Message level should be one of the following values:

When Yii2 is used in debug mode and an error occurs, it shows a error message along with call trace, session, cookie and server info.
Sample image shown below.
In production ready systems, this will not be shown. However, Is there a way to pull this formatted html into a variable in production systems, so that it can be emailed to the developer to ease in debugging errors. If any one has any idea, please let me know.
I tried using \Yii::$app->mailer->render() passing #vendor/yiisoft/yii2/views/errorHandler/exception.php as view, ['exception => $ex] as data, layout file as parameters. I'm getting undefined variable handler error.

I am in the process of making a simple image viewer in VB.NET. I want to be able to open an image with my application. How does VB.NET receive the URL of the file that the user is trying to open?
Seems simple but without knowing key terms, my Google searches are returning completely the wrong things!
You want to inspect the Environment.CommandLine Property
This property provides access to the program name and any arguments specified on the command line when the current process was started.
The program name can include path information, but is not required to do so. Use the GetCommandLineArgs method to retrieve the command-line information parsed and stored in an array of strings.
I am using SoapUI with Groovy script and running into an issue when calling multiple APIs. In the system I am testing one WSDL/API handles the account registration, and returns an authenticator. I then use that returned authenticator to call a different WSDL/API and verify some information. I am able to call each of these WSDLs/APIs separate but when I put them together in a Groovy Script it doesn't work.
testRunner.runTestStepByName("RegisterUser");
testRunner.runTestStepByName("Property Transfer");
if(props.getPropertyValue("userCreated") == "success"){
testRunner.runTestStepByName("AuthenticateStoreUser");
To explain the first line will run the TestStep "RegisterUser". I then do a "Property Transfer" step which takes a few response values from "RegisterUser" - the first is "Status" to see if it succeeded or failed, second is the "Authenticator". I then do an if statement to check if "RegisterUser" succeeded then attempt to call "AuthenticateStoreUser". At this point everything looks fine. Though when it calls "AuthenticateStoreUser" it shows the thinking bar then fails like a timeout, and if I check the "raw" tab for the request it says
<missing xml data>.
Note, that if I try the "AuthenticateStoreUser" by itself the call works fine. It is only after calling "RegisterUser" in the Groovy Script that it behaves strange. I have tried this with a few different calls and believe it is an issue calling two different APIs.
Has anyone dealt with this scenario, or can provide further direction to what may be happening?
(I would have preferred to simply comment on the question, but I don't have enough rep yet)
Have you checked the Error log tab at the bottom when this occurs? If so, what does it say and is there a stacktrace you could share?
Say I have a WCF app hosted in IIS. And in that app I run this line of code:
Console.WriteLine("Testing, testing 1 2 3");
Where will that be written to? Or is it ignored and just lost?
Is there someway to capture it when needed?
Nowhere. More specifically:
NullStream, which is defined as "A Stream with no backing store.".
All the methods do nothing or return nothing. It is an internal class
to Stream. The following code is taken from Microsoft's source code.
Basically, when one of the Console write methods is call the first
time, a call is made to the Windows API function GetStdHandle for
"standard output". If no handle is returned a NullStream is created
and used.

actually, the same answer goes to on to address the second part of your question too:
To actually redirect Console output, regardless of the project type, use
Console.SetOut(New System.IO.StreamWriter("C:\ConsoleOutput.txt")),
I am curious about the proper way to stop a user from activating my plugin if their system does not meet certain requirements. Doing the checks is easy and I don't need any help with that, I am more curious how to tell WordPress to exit and display an error message.
Currently I have tried both exit($error_message) and die($error_message) in the activation hook method. While my message is displayed and the plugin is not activated, a message saying Fatal Error is also displayed (see image below).
Does anyone know of a better way, that would display my message in a proper error box without displaying Fatal error, it just looks really bad for new users to see that.
Thanks for any help in advance.
This is a little undocumented, as you might have noticed. Instead of die(), do it like this:
$plugin = dirname(__FILE__) . '/functions.php';
deactivate_plugins($plugin);
wp_die('<p>The <strong>X</strong> plugin requires version WordPress 2.8 or greater.</p>','Plugin Activation Error',array('response'=>200,'back_link'=>TRUE));
The lines above wp_die() are to deactivate this plugin. Note that we use functions.php in this case because that's where I have my Plugin Name meta data comment declaration -- and if you use a different file, then change the code above. Note that the path is very specific for a match. So, if you want to see what your path would normally be, use print_r(get_option('active_plugins'));die(); to dump that out so that you know what path you need. Since I had a plugin_code.php where the rest of my plugin code was, and since it was in the same directory as functions.php, I merely had to do dirname(__FILE__) for the proper path.
Note that the end of the wp_die() statement is important because it provides a backlink and prevents an error 500 (which is the default Apache code for wp_die()).
It is only a idea though. Try checking the wordpress version and compare then use php to through custom exception/error. PHP 5.0 try catch can be a good way to do it. Here is some resources.

You can try the first link. It is pretty basic. Thanks! hope the information will be helpful.
