Error handling: distinguishing between 'fatal' errors and 'unexpected input' errors

Tag : cpp , By : OlioEngr
Date : March 29 2020, 07:55 AM
wish helps you Your design makes good sense to me: Initialize completely or throw an exception. The only alternatives which come to mind are:
status codes best-effort initialization with status member functions to find out what portions are valid

Separate internal errors from client errors in custom WCF error handling?

wish help you to fix your issue I believe that the exception that is thrown by the serializer for invalid XML is an InvalidOperationException with inner exception of type System.Runtime.Serialization.SerializationException
If you detect this, you can do the required error specific processing. For example:
public bool HandleError(Exception error)
   string output = "Unknown error";

   if (error.InnerException is System.Runtime.Serialization.SerializationException)
      output = "Malformed message";

   TraceSource traceSource = new TraceSource("YourTraceSource");
   traceSource.TraceEvent(TraceEventType.Error, 0, output);

   return false;
public void ProvideFault(Exception error, MessageVersion version, ref Message fault)
    if (error.InnerException is System.Runtime.Serialization.SerializationException)
       //set malformed message status code (400?)
       //set other status code


AngularJS error handling: show errors based on array of errors

it should still fix some issue You can use an ng-repeat to create an element with ng-message for each one:
<div ng-messages="myForm.myName.$error" style="color:red; padding-left: 60px;">
  <div ng-message="{{key}}" ng-repeat="(key, errorMessage) in errors">{{ errorMessage }}</div>
$scope.errors= {
  required: 'You did not enter your name',
  minlength: 'Your name is less than 5 symbols',
  maxlength: 'Yr name is 6+ symbols'

Handling errors from Swift 2.0 String object functions

To fix the issue you can do So the problem String startIndex and characters functions do not throw and exception that can be caught by the swift do try catch block. See The Swift Programming Language (Swift 2.1) - Error Handling documentation for more info.
So I rewrote the code to deal with parsing of the integer without crashing
func parseBatteeryLevel(inputStr : String) -> Int {
    if inputStr.hasPrefix("BATT") && inputStr.containsString("%") {
        let start = inputStr.startIndex.advancedBy(5)
        let indexOfPercent = inputStr.characters.indexOf("%")

        if (indexOfPercent != nil) {
            let end = indexOfPercent!.advancedBy(-1)
            let batteryLevel = inputStr.substringWithRange(start...end)

            if let level = Int(batteryLevel) {
                return level

        return 0

    } else {
        print("Return Value Parse Error: \"\(inputStr)\"")
        return 0
