|Resolution on my laptop and pc for my program|
Instead of Windows Forms, you should use WPF, it solve that kind of issue.
Look at Resolution independent or monitor size independent WPF apps.
You can with VS'12 create WPF UI with C++/CLI
it can provide an easy integration of your C++ native code.
|How to host server from laptop?|
connect to 127.0.0.1 instead of your public ip.
127.0.0.1 is called localhost, and always points to your own machine.
That way it doesn't matter if any NAT routing firewalls or anonymous proxy
servers are hiding your local network IP from whatismyipaddress.com

You can use two HC-05 Serial Port Bluetooth Module.
You can find a lot of tutorials like this explaining how to deal with them.
|How can i redirect my laptop mic to gsm modem input..?|
It is not that easy. You see, the modem hardware in a laptop is not
connected to the audio system in any way. So there is no physical way to
route the output of the sound chip to the telephone line connected to the
However, some modems support a AT+VTX command that allows you to send
uncompressed, 8-bits sampled audio at 8 kHz. That should let you do what
you want to achieve.
Wikipedia explains the basics of this approach nicely.
|USB transfer speed between tablets and laptop|
if your using a USB hub from you Mac it will slow down but not by much. Its
because you will be using more bandwidth of the USB XHCI Host Controller.
So the devices needs to split speeds to how ever many locations you are
copying to and files copying concurrently. Also the CPU needs to work
slightly harder therefore slowing down other processes.
However on ADB the difference is negligible. You will not be able to tell
I'm pretty sure this is the case anyways
|AS3 slow webcam with 1080p on i3 laptop|
The simple truth is that Flash's performance is not good enough for
realtime video applications.
Maybe lag would be better if you could attach your webcam to StageVideo
(GPU decoding) instead of using the old Video class. Or you could simply
lower the resolution...
If you want to develop realtime video applications you should take a look
at Cinder, or OpenFrameworks instead. Both use C++ and performance is
amazing. I have personally done projects involving 4k video on multiple
monitors with Cinder.
Another option would be using Max MSP, much more powerful than Flash in
terms of video performance, and you program visually using nodes and boxes.
|Viewport userscalable for laptop/desktop|
The viewport meta tag doesn't affect desktop browsers. It is purely for
targeting mobile browsers.
You can use the following CSS to try and prevent text zooming in desktop
However, this is experimental only and widely unsupported; See Moz
Personally, I think that preventing a user from zooming in a browser will
lead to awful accessibility. Some users need to zoom in to consume content
on the web.
If you're interested in creating a webpage that functions correctly and is
still accessible, check out the W3 accessibility guidelines: http://www
|Emulating an XBox 360 controller from (not for, from) a laptop|
If you have access to a development console and the SDK I could help you
out, the task is essentially impossible with a retail console and your
laptop or xbox would require some hardware modifications to work properly,
unless you want to connect via a USB. It might be more plausible then.
Regardless, if you have access to the proper software I might be able to
lend you a hand.
|Setting up Java compiler on Windows laptop|
It looks correct. Did you restart the Command prompt every time you changed
the PATH variable ? Also there's supposed to be only one path variable, so
you're supposed to edit the existing one, entries are separated by a

|Java Robot class working in laptop but not pc|
Surely the simple answer to this is not to cheat at games?
Try adding e.printStackTrace() to your catch block and look to see if there
are errors on the pc version and not on the laptop.
|W3C geolocation API's watchPosition isn't working on GPS-equipped laptop when offline|
I had this same problem using a Getac laptop with a gps chip. I extensively
tested Chrome 33.0.1750.117, Firefox 27.0.1, IE 11.0.9600.16518 and Opera
20.0 and found that none of them use the local GPS chip. All of them
instead call out to either Google or MS's location api. I guess this is
because the browser implementors assumed that desktop operating systems
like Windows and OSX do not have local GPS chips accessible to them. If
they do not have an Internet connection, they cannot get their location.
On iOS and Android, they made a different choice in their browser
implementations and do in fact use the local GPS.
The only solution I found for the laptop/desktop use case if you want get
results from the local GPS chip is to integrate with it directly using
GpsGate, which is a program y
|I'm not able to get any Linux Distro work on my Samsugn laptop. Any suggestions?|
If the hardware support for your laptop is not great on any Linux
distribution, you can try out virtualization (vmware, virtual box, ...).
With help of this software you install your favourite Linux distribution in
a 'virtual machine' and can use it from within Windows.
|Can I run an app on a real device (iPhone) from a laptop (mac) with Appium - WebDriver?|
The absolute path is a filepath to an application on your Mac that Appium
will grab and install before starting the test you are trying to run.
Currently the way that people are making this work for getting Mobile
Safari open is using an absolute path to a program like SafariLauncher
which opens Mobile Safari for you. After that happens you can retrieve the
window handle of the webview within Safari and start running normal
This workaround is discussed at length here. I can confirm that it works,
but the timing of all these components working together is a bit janky,
speaking from my testing experience.
For reference, I believe these are the capabilities that I used to get
myself up and running.
|using QT process to get sensor information from the laptop using command line|
process->start("sensors | grep "Core"");
The problem here is that the start function takes the first parameter as
the program to execute and then passes subsequent parameters to the program
as arguments, so the | grep and "Core" are being passed to the sensors
command, which is then complaining because it doesn't know what to do with
One way to solve this is to call sensors and get the returned information
with readAllStandardOutput(). You can then either use the Qt string
functions to search for the information you want, or if you set the
standard output file with setStandardOutputFile, you can then call QProcess
with grep on the that file. (Note QTemporaryFile may be of use here).
However, the simplest way would be to create a small command line script
|Connect local rails app on my laptop to heroku database|
Try something like this
host: HOSTNAME_FROM_HEROKU # something like
to get the values, you need to run the following command
$ heroku pg:credentials DATABASE
Then start your app in production env
$ rails s -e production
Since the database is hosted on the internet, expect lot of latency &
general lack of responsiveness when working with running on local machine
connected to database in the cloud.
PS: Ensure schema version of your local app matches exactly with remote
database on heroku. Otherwise, there is a chance of dataloss when running
|Thermal Printer - Laptop via FTDI Basic Board and C#|
It looks to me like your wiring might not be correct.
TX (transmit) on the FTDI board should be connected to RX (receive) on the
printer. Likewise, RX (receive) on the FTDI board should be connected to TX
(transmit) on the printer.
See this tutorial for an example with further explanation:

Are you using 127.0.0.1 or localhost for your IP? If so, you will need to
use the actual IP of your machine when testing the app. This is because
when you load the app into a device or simulator, 127.0.0.1 will resolve to
the actual device or emulator itself, not your machine. (If using Android
emulator, you can use 10.0.2.2 to get to your localhost on the machine, see

|Copied my asp.net project folder to open it in my laptop, and css stoped working|
I think one common mistake is having mismatching paths when you copy from
one machine to another (at least in my workarea it is!) did you double
check the paths to your CSS in code and filesystem? if the ASP.Net engine
cant find the files it wont be able to use them.
|Android Socket doesn't connect to laptop server - but local Java program can|
Oh boy this is silly and embarrassing. Basically I was using the wrong IP
In Windows, use ipconfig (Linux: ifconfig), and choose the IP address
corresponding to Wireless LAN (wlan). I was using another IP address
corresponding to a virtual machine or some crap.
Hope this helps someone else in the future, I hate these kind of issues.
