  • 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.

  • Interesting task using random numbers only

    - by psihodelia
    Given any number of the random real numbers from the interval [0,1] is there exist any method to construct a floating point number with zero decimal part? Your algorithm can use only random() function calls and no variables or constants. No constants and variables are allowed, no type casting is allowed. You can use for/while, if/else or any other programming language operands.

  • Good C++ Debugging/IDE Environment for Linux?

    - by Brandon Pelfrey
    I have a friend who is trying to make the switch to Linux, but is hung up on the apparent lack of debugging/IDE environments for C++, especially as they relate to template programming. He has been using visual studio for years and is maybe a little spoiled by their awesome IDE. Does anyone have any good suggestions for an environment where he can, under Linux, develop and debug with all of the usual things (Breakpoints, line highlighting for compilation errors, step in/over/out/etc, etc) that he's accustomed to? Thanks!

  • 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?

  • 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.

  • 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?

  • Evaluating and graphing functions in Matlab

    - by thiol3
    New to programming, I am trying to graph the following Gaussian function in Matlab (should graph in 3 dimensions) but am making some mistakes somewhere. What is wrong? sigma = 1 for i = 1:20 for j = 1:20 z(i,j) = (1/(2*pi*sigma^2))*exp(-(i^2+j^2)/(2*sigma^2)); end end surf(z)

    - by johncatfish
    I'm new to CE programming and I have a Marvel device PXA270 with Windows CE 5.0 installed. The device has one usb port. I wonder if there's ANYTHING I can try to connect a 3G-HDSPA usb stick to it. When plugged it only recognises its folders as a pendrive would do, but no Internet. Thx.

  • How to communicate with a USB device under Windows and Java?

    - by Gili
    I'd like to communicate with a USB device under Windows and Java but I can't find a good library to do so. I don't want the user to have to install any extra hardware or device drivers to make this work. That is, I want to be able to interact with USB just like other Windows applications do. I am familiar with jUSB and JSR 80 but both seem to be dead projects (at least for Windows).

  • Has anyone had trouble with Intellisense in Visual Studio when using UltraVNC?

    - by mullala
    Hi, a colleague and I are trying pair programming for the first time. We both remote into a development machine; I'm using RemoteDesktop and my colleague is using UltraVNC. This works great except that he can't see the Intellisense dropdown in Visual Studio 2008. According to online posts, this may be something to do with DirectDraw, but I don't see much by way of a workaround. Has anyone else experienced this? Thanks, Andrew

  • 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. I think there is a problem with the naming of the divs but perhaps there is something else to take care of? Could someone post the simplest possible solution? many thanks

  • Any application to bind documents of different kind

    - by Codeslayer
    A situation that may be quite common in offices is: We communicate with clients over e-mails, exchange documents and spreadsheets with them. Is there any tool which will help me in binding all these outputs. Maybe I may get flamed on this as this is not exactly a programming question. But some inputs may certainly help me. Thanx
