So I've built a Windows installer for my Electron app using https://github.com/electron/grunt-electron-installer.
I'm not sure how to launch my app on system start up, like when the user reboots their computer. I suspect it's something I need to do on --squirrel-install but I can't find any documentation on how to do so.
Ideally I would provide a menu option for the user to enable/disable this behaviour.
If you are using electron on Windows/MAC, there is an existing api which you can use to easily auto start your electron APP：
_electron.app.setLoginItemSettings({
openAtLogin: true,
path: _electron.app.getPath('exe')
})
the reference can be found here:
https://electronjs.org/docs/api/app#appsetloginitemsettingssettings-macos-windows
This can be done in a few different ways. The method i used to do this on a windows OS was to use the node winreg module, this allowed me to add a registry key that launched that app on startup. I use this method on a settings window in the application that has some user settings:
function setKeyValue () {
var regKey = new winreg({
hive: winreg.HKCU,
key: '\\Software\\Microsoft\\Windows\\CurrentVersion\\Run'
});
regKey.set('Your_Application_Name', winreg.REG_SZ, '"' + process.execPath + '"', function (err) {
if (!err) {
//notify user?
}
});
I also have the opposite method that removes the reg key regKey.remove if the user disables the app launch on startup.
Alternatively, i have recently seen this node module: auto-launch ,this allows you to set whether the app launches on startup on Mac, Windows and Linux, and therefore might be more useful for you.

I implemented launch at login for my application using this tutorial:
https://blog.timschroeder.net/2012/07/03/the-launch-at-login-sandbox-project/
Basically you would need to implement a Helper app that will be registered to start at login and the Helper will launch your application.
The problem is that I would like to launch my application hidden and for that I need to pass it one argument. Unfortunately I didn't find any way to do that.
I found these methods to launch an App:
//Works to launch the app but no way to pass arg
var app = SBApplication.FromBundleIdentifier(PackageId);
app?.Activate();
//Same issue here
NSWorkspace.SharedWorkspace.OpenFile("/Applications/HelloWorld.app")
//If you run the code bellow outside of the sandbox it works fine.
//Inside of the sandbox it just launches the app but without args
var aTask = NSTask.LaunchFromPath("/usr/bin/open",
new string[] { "-a","HelloWorld.app", "--args", "--hidden" });
aTask.Launch();
I'm trying to use the setRepresentedFilename option for my app's browserwindow, but it doesn't seem to do anything.
I don't get errors, and any path (resolved or hard-coded) does not change the titlebar to the file's name.
app.on('open-file', function(ev, path) {
win.setRepresentedFilename( path );
});
The app is packaged for Mac, so unless macOS versions is involved in some way, I'm not sure why it's not working.
Am I missing something here? The docs for this is not in-depth and provides only a basic example that apparently 'works'.
Seems it was an order of operations problem, the set command should be executed when the app has finished loading. For example:
win.webContents.on('did-finish-load', function() {
win.setRepresentedFilename( filePath );
});
The above should work. You'll have to handle it such that you have the url to pass. You can use ipcMain and such.
We have a ColdFusion 8 application running in JRun4 on Windows Server 2003.
How do we detect (& display) whether the debugger is running with Allow Line Debugging enabled in CF Administrator. After detecting, we want to display a warning on the application that the debugger is running.
You should be able to use the ColdFusion Administrator API for this. Of course you will need the security/permissions in order to use this. If you are using sandbox security, enable access to the cf_web_root/CFIDE/adminapi directory to use the Administrator API. Basically the Administrator API gives you programmatic access to most of the ColdFusion Administrator settings.
From the documentation:
You can use the Administrator API to perform most ColdFusion Administrator tasks programmatically. The Administrator API consists of a set of ColdFusion components (CFCs) that contain methods you call to perform Administrator tasks.
The CFC for managing the debug settings is debugging.cfc.
Here is some pseudo code (this has not been tested):
<cfscript>
// Instantiate the administrator.cfc
adminObj = createObject("component","cfide.adminapi.administrator");
// Call the administrator.cfc login method, passing the ColdFusion Administrator password
adminObj.login("#password#","#username#");
// Instantiate the debugging CFC
debugObj = createObject("component","cfide.adminapi.debugging");
// Call the desired CFC method
if (debugObj.isLineDebuggerEnabled()) {
if (debugObj.isLineDebuggerRunning()) {
// Stop line debugger
debugObj.stopLineDebugger();
}
// Disable the line debugger
debugObj.setLineDebuggerEnabled(enabled="false");
}
</cfscript>
That should get you started. Here is some documentation on the debugging.cfc and it's methods.

I can not find how to start WPS client in Windows 10 from command prompt or powershell. When I used Linux, everything was really ease with wla_supplicant (wpa_cli wps_pbc). Is there something similar in Windows?
Does anyone know how to set up Wi-Fi network (over WPS) key without human input in Windows?
I also tried WCN (Windows Connect Now) from Microsoft as it implements WPS features. I got also samples from Windows SDK on WCN, but they could not get key by WPS (it faild). But if I use Windows user interface to connect wiothout PIN, everyting seems to be pretty fine.
I am sure that there is possibility to do that, it is very important to perform Wifi Protected Setup by button start from the command prompt or app (C++/C#) without human intrusion or input (once WPS is on air, Windows should automatically get the network key and connect then).
I don't know if it's too late to answer, just put what I know in here and hope it can help.
First, if your system has updated to 16299(Fall Creator Update), you can just simply use new wifi api from UWP.
Install newest Windows SDK, create a C# console project, target C# version to at least 7.1, then add two reference to the project.
C:\Program Files (x86)\Reference Assemblies\Microsoft\Framework.NETCore\v4.5\System.Runtime.WindowsRuntime.dll
C:\Program Files (x86)\Windows Kits\10\UnionMetadata\10.0.16299.0\Windows.winmd
After all of that , code in below should work.
using System;
using System.Threading.Tasks;
using Windows.Devices.Enumeration;
using Windows.Devices.WiFi;
class Program
{
static async Task Main(string[] args)
{
var dic = await DeviceInformation.FindAllAsync(WiFiAdapter.GetDeviceSelector());
if (dic.Count > 0)
{
var adapter = await WiFiAdapter.FromIdAsync(dic[0].Id);
foreach (var an in adapter.NetworkReport.AvailableNetworks)
{
if (an.Ssid == "Ssid which you want to connect to.")
{
// Fouth parameter which is ssid can not be set to null even if we provided
// first one, or an exception will be thrown.
await adapter.ConnectAsync(an, WiFiReconnectionKind.Manual, null, "",
WiFiConnectionMethod.WpsPushButton);
}
}
}
}
}
Build and run the exe, then push your router's button, your pc will be connect to the router.
But if you can not update to 16299, WCN will be your only choice. You may already notice that if call IWCNDevic::Connect frist with push-button method, the WSC(Wifi Simple Configuration) session will fail. That's because WNC would not start a push-button session as a enrollee, but only as a registrar. That means you have to ensure that router's button has been pushed before you call IWCNDevic::Connect. The way to do that is using Native Wifi api to scan your router repeatedly, analyse the newest WSC information element from the scan result, confirm that Selected Registrar attribute has been set to true and Device Password Id attribute has been set to 4. After that, query the IWCNDevice and call Connect function will succeed. Then you can call IWCNDevice::GetNetworkProfile to get a profile that can use to connect to the router. Because it's too much of code, I will only list the main wifi api that will be used.
WlanEnuminterfaces: Use to get a available wifi interface.
WlanRegisterNotification: Use to register a callback to handle scan an connect results.
WlanScan: Use to scan a specified wifi BSS.
WlanGetNetworkBsslist: Use to get newest BSS information after scan.
WlanSetProfile: Use to save profile for a BSS.
WlanConnect: Use to connect to a BSS.
And about the WSC information element and it's attributes, you can find all the information from Wi-Fi Simple Configuration Technical Specification v2.0.5.
For Krisz. About timeout.
You can't cast IAsyncOperation to Task directly. The right way to do that is using AsTask method. And also, you should cancel ConnectAsync after timeout.
Sample code:
var t = adapter.ConnectAsync(an, WiFiReconnectionKind.Manual, null, "",
WiFiConnectionMethod.WpsPushButton).AsTask();
if (!t.Wait(10000))
t.AsAsyncOperation().Cancel();
I am creating a firefox OS application, I want the user to be able to share a link through any application installed and eligible (facebook, twitter etc). I saw android has this kind of feature and firefox OS has it as well, as I saw it in one of it's built in applications. Went through Web API, didn't find a suitable match,
Any ideas how to do it?
This is the intended use of the Web Activity API . The idea is that applications register to handle activities like share. The Firefox OS Boiler Plate app has several examples of using Web Activities. In that example a user could share a url using code like:
var share = document.querySelector("#share");
if (share) {
share.onclick = function () {
new MozActivity({
name: "share",
data: {
number: 1,
url: "http://robertnyman.com"
}
});
};
}
Any app that handles the share activity will be shown allowing the user to pick the proper app to handle the share.
