Wix ServiceInstall specify account



I created a service installer with WiX. The setup runs with InstallPrivileges="elevated". My service has to access a distant folder, so I want to specify the user attribute to be sure that the service will have sufficient privileges.


InstallPrivileges="elevated"



I checked the WiX documentation but I only found how to define local system as account.



How can I define a user for the service (maybe the current user)?


<ServiceInstall Id="ServiceInstaller"
Type="ownProcess"
Vital="yes"
Name="$(var.service)"
DisplayName="$(var.product)"
Start="auto"
Account="LocalSystem"
ErrorControl="normal" />





You should define "distant folder", is it a network folder? A share name? It seems that you've decided the solution is to give the service a set of credentials, but the problem of accessing a "distant folder" is not well defined.

Credentials: You need to specify an account and a password, maybe something like show below (no time to test right now). Note that public properties can be set when installing from the command line using msiexec.exe`, or via MSI dialogs:


msiexec.exe


<..>

<Property Id="SERVICEACCOUNT" Hidden="yes" Value="MyUser"/>
<Property Id="SERVICEPASSWORD" Hidden="yes" Value="MyPass"/>

<..>

<Component>

<ServiceInstall Name="MyService" Start="auto" ErrorControl="normal" Type="ownProcess"
Account="[SERVICEACCOUNT]" Password="[SERVICEPASSWORD]" >
</ServiceInstall>

<ServiceControl Name="MyService" Start="install" Stop="both" Wait="yes" Remove="uninstall" />

</Component>



Create Local Users: If you need to create local users on the machine you install on, you can use the WiX Util features. Perhaps see this sample on github. Search for "util:User".


"util:User"



Mandatory preaching :-): Personally I don't like services running with user credentials - both for security reasons and for practical reasons (managing the password change process without causing major service disruptions).


security reasons


practical reasons



More in Section 12 here: How do I avoid common design flaws in my WiX / MSI deployment solution? Please check the links as well - maybe particularly on "managed service accounts"? (step-by-step).

Firebase Auth - with Email and Password - Check user already registered

Clash Royale CLAN TAG #URR8PPP Firebase Auth - with Email and Password - Check user already registered I want to check when a user attempts to signup with createUserWithEmailAndPassword() in Firebase user Authentication method, this user is already registered with my app. createUserWithEmailAndPassword() 8 Answers 8 To detect whether a user with that email address already exists, you can detect when the call to createUserWithEmailAndPassword () fails with auth/email-already-in-use . I see that @Srinivasan just posted an answer for this. createUserWithEmailAndPassword () auth/email-already-in-use Alternatively, you can detect that an email address is already used by calling fetchSignInMethodsForEmail() (previous called fetchProvidersForEmail() ). fetchSignInMethodsForEmail() fetchProvidersForEmail() When the user trying to create an user with same email address, the task response will be "Response: The email address is already in use by another account." mFirebas

Clash Royale CLAN TAG #URR8PPP Dynamically update html content plain JS So I have a script bound in my index.html, which literally has to fetch an array of jsons from an api, then dynamically update my page when get response. But as a result I'm getting an as the only update of my page. here is my script fetch(url) .then((resp) => resp.json()) .then((resp) => resp.results.forEach(item => fetch(item.url) .then((response)=> response.json()) .then((response) => pokeArr.push(response)) .catch(console.log) ) ).catch(console.log) const filler = () => if(!pokeArr) return 0 pokeArr.map((i,j)=> return `<tr>$i.name</tr>` ) const pokeindex = () => document.getElementById('a').appendChild(document.createElement(filler())) pokeindex() When I'm consoling it, I can see in the console all the responses I get, so I'm at least doing the fetching part right. What's parberakan ? What's pokeArr ? – T.J. Crowder Aug 8 at 12

How to determine optimal route across keyboard

Image
Clash Royale CLAN TAG #URR8PPP How to determine optimal route across keyboard I'm trying to automate the typing process in a video game. Players are given an on-screen QWERTY keyboard layout that they can navigate with the control stick (up, down, left, right) in order to select a letter to type. I was wondering if there was a module for Python (or some other resource I could explore) that would help my program find a path across the keyboard as it types each letter in a given message. In other words, if the first letter typed was "A" and the next letter was "B", the module would know that the program should move 1 space down on the keyboard and 4 spaces to the right. Currently, I have the program resetting to the "G" key after each letter is typed (allowing me to use fixed-directions as the program parses each character in the desired message). As you can imagine, this is quite inefficient and defeats the purpose of automating the typing in the fir
