• How do I superimpose one bitmap image on another in GDI+?

  - by Old Man

  Using GDI+ I've made a heatmap bmp and I'd like to superimpose it on top of my bmp map. I've saved the two bmps to disk, and they look good, I just need a way to put them together. Is there any way to do this, perhaps using the Graphics object? How is transparency/alpa involved? I'm very new to GDI programming so please be as specific as possible.

• Developing iPhone app to Run on iPad - Auto Set 2x

  - by R.J.

  Is there a way to programmatically set the iPad to run the iPhone app at 2x as it is launched (yet keep the iPhone app native). I understand I can create NIB files for each hardware platform, but for ease, I just would rather the app launch as if the user had tapped the 2x on the iPad. Thanks...R.J.

• Real world examples of Rx

  - by theburningmonk

  I've been playing around with the Reactive Extension for a little while now, but mostly limited to handling/composing user driven events within a WPF frontend. It's such a powerful, new way of doing async programming, and I'm curious as to what other people are doing with it, and where do you think it might be able to improve the way we're currently doing things?

• lock-free memory reclamation with 64bit pointers

  - by JDonner

  Herlihy and Shavit's book (The Art of Multiprocessor Programming) solution to memory reclamation uses Java's AtomicStampedReference<T>;. To write one in C++ for the x86_64 I imagine requires at least a 12 byte swap operation - 8 for a 64bit pointer and 4 for the int. Is there x86 hardware support for this and if not, any pointers on how to do wait-free memory reclamation without it?

• Unable to display google maps in a dojo layout

  - by Jens

  Dear All, I am a real newbie in programming and now I have to combine Google Maps and Dojo. Both alone are fine but when I try to implement a Google Map into a Dojo content pane which is embedded in a border-container it simply does not work.

• UIWebView doesn't scroll to the bottom of the webpage loaded/created

  - by tom

  I have a UIWebView inside a normal UIViewController. The content of the UIWebView is programming/dynamically created in my program, and it could be very long (multiple table rows). Somehow, after loading, the page won't scroll more then one and half screen of content when swipe on the screen. Because of that I can only see the beginning few rows of data, but not the many others after them. Why is that?
