PyObject* args = Py_BuildValue("(s)", "An arg"); PyObject* method = PyWHATGOESHERE(obj, "foo"); PyObject* ret = PyWHATGOESHERE(obj, method, args); if (!ret) { // check error... } This would be the equivalent of >>> ret = obj.foo("An arg")Read the article

Why is my BeginInvoke method not async?
- by Petr
Hi, In order to avoid freezing of GUI, I wanted to run method connecting to DB asynchronously. Therefore I have written this: DelegatLoginu dl = ConnectDB; IAsyncResult ar=dl.BeginInvoke(null, null); bool result = (bool)dl.EndInvoke(ar); But it is still freezing and I do not understand why - I though BeginInvoke assures that method it references is run in another thread. Thank you!Read the article

Passing data to overridden base method in C#
- by UpTheCreek
Bit of a dumb question, but I'm wondering what the accepted way of passing data from back to an overridden base method is in c#. e.g. I guess I could do: class A { int x; public virtual void DoStuff() { Console.WriteLine(x); } } class B : A { public override void DoStuff() { x = 1; base.DoStuff(); } } But is there a better method that for example doesn't require the use of a member variable?Read the article

Extending a Java Swing class in Clojure
- by mikera
I'm trying to extend a Java Swing component in Clojure, i.e. I want to extend a javax.swing.JComponent and add some custom methods implemented in pure Clojure in addition to all the standard inherited methods. I've tried using "proxy" which works great if I just want a single instance (in the same way as an anonymous inner class). However I'd really like a named class so that I can generate an arbitrary number of instances. What's the recommended way of doing this?Read the article
