callback

How can I detect which callback from an unmanaged dll causes a protected memory exception?

I get a protected memory exception, but how can I know which call caused it, and why the callback function has moved? All the calls to unmanaged code are done in the same class as the callback functions, so I suppose that the addresses should not change, or am I totally wrong here? ...

I'm trying to give my plugin callback functionality, and I'd like for it to operate in a somewhat traditional way: myPlugin({options}, function() { /* code to execute */ }); or myPlugin({options}, anotherFunction()); How do I handle that parameter in the code?

Callbacks in Thrift Asynchronous Functions?

Hi all, In Thrift it is possible to use the oneway modifier to specify a call as asynchronous. Apparently, it's not possible to define a callback, though, to be executed when the execution of the function is completed. It seems that the only possibility I have is to give my Thrift client (PHP) some "server" capabilities, so that, when...

Programming pattern to flatten deeply nested ajax callbacks?

I've inherited JavaScript code where the success callback of an Ajax handler initiates another Ajax call where the success callback may or may not initiate another Ajax call. This leads to deeply nested anonymous functions. Maybe there is a clever programming pattern that avoids the deep-nesting and is more DRY. Also, there is the proble...

Is there a work around for addEventListener callbacks with return value?

Hi, I'm currently experimenting with custom (level 2 DOM) events and I've now arrived at the problem that addEventListener() will not accept callbacks that return a value -- or at least I'm unfamiliar with the proper approach to this. Basically what I want is this: addEventListener("customEvent", function() { r...
