Reducing duplicate error handling code in C#?

To fix the issue you can do This looks like an excellent opportunity to have a look at Aspect Oriented Programming. Here is a good article on AOP in .NET. The general idea is that you'd extract the cross-functional concern (i.e. Retry for x hours) into a separate class and then you'd annotate any methods that need to modify their behaviour in that way. Here's how it might look (with a nice extension method on Int32)
code :
[RetryFor( 10.Hours() )]
public void DeleteArchive()
{
  //.. code to just delete the archive
}

Android: reducing code for handling AlertDialog

This might help you You can implement the DialogInterface.OnClickListener in the containing class and monitor the which parameter to see, which button was clicked.
code :
alert.setPositiveButton("Ok", this);
alert.setNegativeButton("No", this);
alert.setNeutralButton("Cancel", this);

public void onClick(DialogInterface dialog, int which) {
    String text = "";

    switch (which)
    {
        case DialogInterface.BUTTON_NEGATIVE:
            text = "Cancel";
    }

    Toast.makeText(getApplicationContext(), 
        text,
        Toast.LENGTH_LONG)
        .show();
}

Reducing Duplicate Cocos2D Code?

wish helps you Currently I am trying to check the screen boundaries by seeing if a CCSprite crossed the top or bottom of the screen. The thing is, I really want to combine the 2 below if statements into 1 statement. Anyway the only difficult thing I am going to have to do is the following. What I do below is move the CCSprite 1 point inwards to enforce the actual screen boundary. But I just do not see how I can do that with one if statement.
code :
CGFloat yNew = MAX(1, MIN(sprite.position.y, size.height - 1));
if (yNew != sprite.position.y) {
    sprite.position = ccp(sprite.position.x, yNew);
    died = YES;
}

c++ parsing protobuf messages with switch/case (reducing duplicate code)

I wish this help you I'm trying to build server application program parsing protobuf packets from client. , You could do something along these lines, I suppose:
code :
std::map<int, std::unique_ptr<google::protobuf::Message>> protocols = {
  {messageTypeA, std::make_unique<protocol::messageA>()},
  {messageTypeB, std::make_unique<protocol::messageB>()},
  {messageTypeC, std::make_unique<protocol::messageC>()}
};

void ProcessPacket(int protocolID, char* packetData, int packetSize) {
  auto it = protocols.find(protocolID);
  assert(it != protocols.end());
  std::unique_ptr<google::protobuf::Message> packet{it->second->New()};
  packet->ParseFromArray(packetData, packetSize);
  std::string messageTypeString = packet->GetTypeName();
  //kind of logging packet procedure goes here
}

Django - Reducing duplicate context code in the view

I hope this helps you . It's just a dictionary, so set the ones that are consistent across all of the conditions, and then add the other one in in your if/else logic.
code :
def check_view(request):
    context = {'variablea':a, 'variableb':b}
    if user.is_authenticated:
        context['variablec'] = c 
    else: 
        context['variabled'] = d

    return render(request, 'user-template.html', context)

I wish did fix the issue. You already have two methods. You can't reduce by adding one more.
But you can have one method instead of two. e.g.
