The title of the question explains pretty much the whole question. I've been programming a console application for about a week now and I want to migrate over to a GUI. Sounds simple, but I'm running into some errors. I would add them here, but it seems pretty obvious that there are some preparations I need to make to move over to GUI that I haven't made yet.
So, where do I start?
Thanks,
-P
EDIT:
LIBCMT.lib(wincrt0.obj) : error LNK2001: unresolved external symbol _WinMain#16
That's all I've got so far, but by the looks of it it may be a big problem to tackle.
And if I didn't make it clear, my objective is to change from the console subsystem to the windows subsystem.
Looks like WinMain is set as the entry point of your application (as a Windows subsystem app), where you probably have a main() function somewhere from your console application. Set the entry point to main() or implement WinMain to resolve the linker issue.

I want to create a C or C++ program that automates some things for me.
The idea is as such: I run the program ./a.out and sit back and watch as it opens up three or four new terminal windows and runs various UNIX commands. Is there a way to do this?
I am on a MacBook.
As the comments point out, this is probably best accomplished by a shell script. However, you can execute shell commands from C with the system(3) standard library function. To open a terminal, just run a terminal with a particular command. For example:
system("xterm -e 'echo hello; sleep 5'");

I'm pretty sure this is a hardware issue. Just to prove my point, I loaded up the Blink script and the default startup file, both resulting in the same error. I'm worried I may of fried something or done something similar. I'm fine if the only solution is to buy a new Arduino, I'd just like to know what happened.
Here are is error message from both scripts:
Startup File
Blink Script
No errors occur when compiling, but when the code is sent to the Arduino, that happens. Any ideas on what the problem is?
It's hard to tell you what happened without knowing what you were doing with your board before it stopped working.
This error may have many causes, one possibility is that you downloaded the .org IDE, which has a higher version number. In this case it should be sufficient to uninstall the Arduino IDE, then download the latest .cc IDE from here and install it. Be sure to make a backup of your sketches first.
Your problem may also be a corrupt bootloader, in which case burning the bootloader may help.
If u have another functioning arduino with same processer(atmega328 in my case) than burn bootloader on ur malfunctioning arduino using ur function arduino

I have a windows c++ application which runs under the normal (non-admin) user. I want that no user should be able to close/stop/terminate this application by any means.
Is there any active directory group policy available to achieve this or I need to do some programming for the same
The only way I know is that your app will launch run 2 or more background processes that check every few ms that your app and the other backgrounds are running, if not it re-launches them.This makes it very had or impossible to terminate your app manually.
You application might need to save its state to disk , if it needs to re-launch to the same stat is was when destroyed
you can also disable the close button or whatever can terminate your application. Also disable the taskmanager so users cannot kill your application
There is a technique called hooking which will allow injection of your code into Windows DLL's, altering certain behaviours performed by the operating system.
This would prevent the operating system killing these proccesses using the core DLL's.
There is a downside to this method though as it may flag up as a virus on anti-rootkit systems as this is a technique often used to prevent the user from killing an infection.

Trying to add an Event handler to a scheduled task in ColdFusion11.
I'm supposed to write a component that implements CFIDE.scheduler.ITaskEventHandler and "Specify a dot-delimited CFC path under webroot, for example a.b.server (without the CFC extension)"
I tried to put my component under
ColdFusion11/cfusion/wwwroot
ColdFusion11/cfusion/wwwroot/CFIDE
ColdFusion11/cfusion/wwwroot/CFIDE/scheduler
the Apache webroot
some virtual host webroot
I tried to add some dot notation (?) like CFIDE.scheduler.myEventHandler...
I don't understand if there is some more configuration at server level to understand.
I don't see any error in logs, the scheduler editor just refuse to save an EventHandler he cannot find, with the error
An error occured scheduling the task.
Invalid eventhandler.
Error: Eventhandler myEventHandler could not be found
Any help appreciated
The correct way seems to put the component in ColdFusion11/cfusion/wwwroot/myEventHandler.cfc, set the path as myEventHandler and implement in the component "CFIDE.scheduler.ITaskEventHandler"

I'm a game developer and my current task is to create a game launcher. If you know what is Battle.net, you'll understand what I mean. For the launcher itself we're using the InstallBuilder from Bitrock. But the end user should have a possibility to install actual game pressing a button in the launcher. The launcher then will download files, register them, show progress bar, allow to play a game before full download, create a shortcut etc. - the same way as Battle.net launcher behave.
So, my question - where to start? I suppose that this is platform specific, so for now I'm interested in Windows. I'm using VS2013, Qt.
First of all, you must create an installer which will handle the actual installation of the application. You can then call the installer from your other process (in your case the launcher.)
In Qt you can use the QProcess Class which is documented here. I think that the documentation is really good and will answer most of your questions but what you need to do more or less is this:
QObject *parent;
...
QString program = "./path/to/your/installer";
QStringList arguments;
arguments << "-option" << "argument";
QProcess *myProcess = new QProcess(parent);
myProcess->start(program, arguments);
(Copied pretty much verbatim for the documentation.)
You also have the option of interacting with your installer after its execution start (you can for example read the exit code) so that you can monitor the installation progress form your launcher.
