emulation

I need an unsigned 8 bit integer in Java, and char seems to be the only thing close to that. Although it's double the size, it's unsigned which makes it practical for what I want to use it for (writing a basic emulator which requires unsigned bytes). The problem is that I've heard other programmers say that one shouldn't use char in that manner and should just use int or so. Is this true, and why so? If you need an unsigned 8 bit integer then use byte . It's easy to make it unsigned in arithemtic operations (where actually sign matters) as byteValue & 0xFF In Java: long: [-2^63 , 2^63 - 1] int

as you can probably think I want to install Android ICS in VirtualBox. I have, but I doesnt have Internet connection. I tried servel tutorials for the last hours but it does not work. I dont want to use the Android Emulator. So can somebody help me? how do you get Internet acces in the Virtual Mashine? Thanks I am working on this right now, specifically with ethernet, I found this google group discussion very helpful. Basically what you are going to need to do apply a few patches from two of the users in the discussion, and one from google source for the right menu options. The user "tablet

I am using Windows Mobile 6 Professional Emulator and Windows Mobile Device Center. I connected and cradled the emulator to my computer. I am trying to connect from the browser of the emulator to a webservice that is deployed in the IIS of my computer (same machine where the emulator is installed). If I connect my computer to the internet, I can access any website, including my local WS (using the IP returned by ipConfig). The problem is when I disconnect the computer from the Internet: I cannot access my local web service using the IP (internal one returned by ipconfig), or machine name. Do

When testing Android layouts, I'm constantly building for three different emulators from Eclipse (with ADT), so I have to run three times and then select each one. Is there any configuration or plugin that allows me to press Run once and the application is started in all three? I wish I had a machine powerful enough to run 3 emulators at once! :) I doubt the Android Development Tools can do this for you... the nearest you can probably get is to script something. "adb devices" will get you a list of emulator instances, and then you just need to iterate that list running these two command on

I'm trying to do some Windows Mobile dev in VS2008. The WM app is making a WCF call (or trying to). The emulator and my WCF server are running on the same desktop PC. I found some details about how to configure the network card on the WM5 emulator in conjunction with Virtual PC2007. This does allow me to now surf the net view the emulator, which puts me a lot closer than I was. However, I can't get it to recognise the desktop machine itself, e.g. http://mycomputername/ and http://10.1.1.2/ Obviously, this makes it a bit hard to test the WCF side of things. Have I missed something obvious?

I don't mean to start a war between iPhone vs Windows Phone 7, nor am I against Windows Phone 7. But I've noticed on both of my computers Windows Phone 7 emulator (Beta and CTP) lags like it's running on a crappy last-decade Celeron computer. I have 2 computers: Macbook Pro 13" (2010 Model) with 2.4GHZ Core 2 Duo, 4GB RAM and ASUS G1 with 2.0 GHz Intel Core 2 Duo, 3GB RAM with fresh install of Windows 7. Now iPhone emulator on Mac OS X is on the other hand so much smoother, and loads faster and just has better feel to it. So why is Windows Phone 7 emulator so slow? Is that what we should

I searched little bit for emulation of ESC/POS printer, but didn't found any thing more, then data parsers like this . In few words, I have Linux, I have device connected to my PC via UART/RS-232 port. I need some soft, that will listen to specific COM port, and visualize data sent to be printed to this port (in example saves it as PDF). I don't think there is an out of box solution, but if you can capture the data (and it is a simple enough subset of esc/pos) you could then feed it to a tool like esc2html + wkhtmltopdf. https://github.com/receipt-print-hq/escpos-tools https://wkhtmltopdf.org/
