Camel Errorhandler
VBA, i found this tutorial and i wanted to catch the errors using the GoTo method like in the following example : Sub mySub On Error GoTo myHandler: Workbooks.Open("myWorkbook") ' ' Some Code ' myHandler: MsgBox "EROOR !"

add an Exit Sub statement as explained : Sub mySub On Error GoTo myHandler: Workbooks.Open("myWorkbook") Exit Sub ' ' Some Code ' myHandler: MsgBox "EROOR !" End Sub In that case it exits the method even without error. I also tried : Sub mySub On Error GoTo myHandler: Workbooks.Open("myWorkbook") ' ' Some Code ' myHandler: MsgBox "EROOR !" Exit Sub End Sub But still the same problem, the myHandler is executed even without errors !

For example: app.use(function(err, req, on error res, next) { console.error(err.stack); res.status(500).send('Something broke!'); }); You define error-handling middleware last, after other app.use() and routes calls; for example: var bodyParser = require('body-parser'); var methodOverride = require('method-override'); app.use(bodyParser.urlencoded({ extended: true })); app.use(bodyParser.json()); app.use(methodOverride()); app.use(function(err, req, res, next) { // logic }); Responses from within a middleware function can be in any format that you prefer, on error goto such as an HTML error page, a simple message, or a JSON string. For organizational (and higher-level framework) purposes, you can define several error-handling middleware functions, much like you would with regular middleware functions. For example, if you wanted to define an error-handler for requests made by using XHR, and those without, you might use the following commands: var bodyParser = require('body-parser'); var methodOverride = require('method-override'); app.use(bodyParser.urlencoded({ extended: true })); app.use(bodyParser.json()); app.use(methodOverride()); app.use(logErrors); app.use(clientErrorHandler); app.use(errorHandler); In this example, the generic logErrors might write request and error information to stderr, for example: function logErrors(err, req, res, next) { console.error(err.stack); next(err); } Also in this example, clientErrorHandler is defined as follows; in this case, the error is explicitly passed along to the next one. Notice that when not calling “next” in an error-handling function, you are responsible for writing (and ending) the response. Otherwise those requests will “hang” and will not be eligible for garbage collection. function clientErrorHandler(err, req, res, next) { if (req.xhr) { res.status(500).send({ error: 'Somethin

You can’t predict errors, but you can anticipate them. Each Slim Framework application has an error handler that receives all uncaught PHP exceptions. This error handler also receives the current HTTP request and response objects, too. The error handler must prepare and return an appropriate Response object to be returned to the HTTP client. Default error handler The default error handler is very basic. It sets the Response status code to 500, it sets the Response content type to text/html, and appends a generic error message into the Response body. This is probably not appropriate for production applications. You are strongly encouraged to implement your own Slim application error handler. The default error handler can also include detailed error diagnostic information. To enable this you need to set the displayErrorDetails setting to true: $configuration = [ 'settings' => [ 'displayErrorDetails' => true, ], ]; $c = new \Slim\Container($configuration); $app = new \Slim\App($c); Custom error handler A Slim Framework application’s error handler is a Pimple service. You can substitute your own error handler by defining a custom Pimple factory method with the application container. There are two ways to inject handlers: Pre App $c = new \Slim\Container(); $c['errorHandler'] = function ($c) { return function ($request, $response, $exception) use ($c) { return $c['response']->withStatus(500) ->withHeader('Content-Type', 'text/html') ->write('Something went wrong!'); }; }; $app = new \Slim\App($c); Post App $app = new \Slim\App(); $c = $app->getContainer(); $c['errorHandler'] = function ($c) { return function ($request, $response, $exception) use ($c) { return $c['response']->withStatus(500) ->withHeader('Content-Type', 'text/html') ->write('Something went wrong!'); }; }; In this example, we define a new errorHandler factory that returns a callable. The returned callable accepts three arguments: A \Psr\Http\Message\ServerRequestInterface instance A \Psr\Http\Message\ResponseInterface instance
