Opening a Link/File through button click event

I am still new to the WPF/XAML coding and while learning I encountered another problem. I decided I want to add buttons on the UserControl, that I would like to make them do a few different things. On one of them, I want to open the local default browser and open a webpage link, and in another button, I want to start a local exe/rpm file from a directory in my project called "tools".
For opening the link I tried - WebBrowserTask which is an unrecognized event/task
For the running of the application - Process.Start("thelocation/thefile.exe/rdp"). After that, I tried guiding it to the proper path, but my project doesn't recognize the folder and files inside.
Both tries were unsuccessful.

Try this:
public void DoSomething
{
const string webpageUrl = "https://stackoverflow.com/questions/55778625/";
const string localFile = #"C:\Windows\notepad.exe";
var localTools = $#"{AppDomain.CurrentDomain.BaseDirectory}Tools\SomeTools.exe";
Process.Start(webpageUrl);
Process.Start(localFile);
Process.Start(localTools);
}
to opening an web page your address must be start with http://...

Launching a Windows 10 Store app from C# executable

So here's the gist of my problem: I have a keyboard where I can assign macros and/or launch programs from. I want to include a couple Win10 and Steam applications in that list. So I opted to build an executable "launcher", so to speak.
The code is simplistic in nature. I got Steam url's to work by placing the steam url into Process.Start("steam://rungameid/#####"). I cannot, however, figure out how to get Win10 apps to work. Here's my class:
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}
private void Form1_Load(object sender, EventArgs e)
{
Process.Start(#"explorer.exe shell:AppsFolder\4DF9E0F8.Netflix_mcm4njqhnhss8!Netflix.App");
Process.Start(#"shell:AppsFolder\4DF9E0F8.Netflix_mcm4njqhnhss8!Netflix.App");
Process.Start("netflix://");
Application.Exit();
}
}
Each line of Process.Start() is what I've tried, to no avail.
The bottom line I attempted from this answer, which also did not work
The first line, I can put that in a Run box or from the command line saDand it will launch Netflix, but from the C# application, I get a "System cannot find the file" exception.
Thanks for any direction!

Can you please check if you have installed this app and name you enter in the Process.Start(“ ”) is correct, You can find the names when you open the registry key HKEY_CLASSES_ROOT\Extensions\ContractId\Windows.Protocol\PackageId. Look for the CustomProperties key. It has an attribute Name. I use the below sample to open my photos, It works fine.
private void Form4_Load(object sender, EventArgs e)
{
button2_Click(null,null);
}
private void button2_Click(object sender, EventArgs e)
{
Process.Start("ms-photos://");
}

Instead of
Process.Start(
#"explorer.exe shell:AppsFolder\4DF9E0F8.Netflix_mcm4njqhnhss8!Netflix.App"
);
Do this
Process.Start(
"explorer.exe",
"shell:AppsFolder\4DF9E0F8.Netflix_mcm4njqhnhss8!Netflix.App"
);

I was having the same problem. Currently unable to launch a windows app store application from c#. I used a work around for now. I made a bat file that navigates to the desktop and launches the desktop shortcut link. Then I call my bat file which launches the app store application.
Example of BAT file:
cd\
cd Users\d1\OneDrive\Desktop
"XYZ Games - Shortcut.lnk"
Example Code C#:
Process proc = new Process();
proc.StartInfo.FileName = "launcherXYZGames.bat";
proc.Start();

C# Setup Project run after install

Hello guys I'm new to the forum also programming and need some help about a project.
So I recently start developing a program that firstly must add its path at the end of Registry => Environment => Path.
For this job I created project (MainLogic) which contain a class (Program) that do the job, Installer Class that contains this events below and configured Setup Project. SOURCE
public InstallerClass1()
{
this.Committed += InstallerClass1_Committed;
this.Committing += InstallerClass1_Committing;
}
private void InstallerClass1_Committing(object sender, InstallEventArgs e)
{
//Console.WriteLine("");
//Console.WriteLine("Committing Event occurred.");
//Console.WriteLine("");
}
private void InstallerClass1_Committed(object sender, InstallEventArgs e)
{
Directory.SetCurrentDirectory(Path.GetDirectoryName
(Assembly.GetExecutingAssembly().Location));
Process.Start(Path.GetDirectoryName(
Assembly.GetExecutingAssembly().Location) + "\\MainLogic.exe");
}
The program was installed correctly but MainLogic.exe file I call after installation cause an error and can't start. The exception is Null Reference at MainLogic.Program.Main(String[] args)
Here is a picture for better understanding -
Is there a way to avoid that exception or could you offer me another that will work.
*** Here what i found. I can execute creating and typing in to file. Writing on the console. Probably a lot of other stuff without problem. But when try to execute this peace of code which actually I have to use...
Registry.CurrentUser.OpenSubKey("Pass Key", RegistryKeyPermissionCheck.ReadWriteSubTree).SetValue("Finaly", "Done");
Registry.CurrentUser.Close();
...the exception I described above occurs. Suggestions?
So the main reason for all those "exercises" is because I want to implement ffmpeg in my application.
I guess you are hear about ffmpeg (a video/audio processing program that works in command prompt).
So what I'm working on is to implement it in my project for mp3 extracting from video files but I wanna make it more user friendly so the user can pass commands through GUI and from there my code should do the other job. So ffmpeg works through command prompt (I know there is a wrappers but I'm not very satisfied with what read about) but firstly you have to add his path to Path's value in the registry. And here's where my problem came from.
Maybe it's sounds stupid for you but you know.. when you start something make it all the way.

If course you can just add exception handling and see what goes wrong but you don`t neet that anyway. Try to set the registry key directly in your Installer
[RunInstaller(true)]
public partial class Installer1 : Installer
{
public override void Install(IDictionary stateSaver)
{
base.Install(stateSaver);
const string key_path = "SOFTWARE\\YourCompany\\YourApplication";
const string key_value_name = "InstallationDirectory";
RegistryKey key = Registry.LocalMachine.OpenSubKey(key_path, Microsoft.Win32.RegistryKeyPermissionCheck.ReadWriteSubTree);
if (key == null)
{
key = Registry.LocalMachine.CreateSubKey(key_path);
}
string tgt_dir = "someDirectory";
key.SetValue(key_value_name, tgt_dir);
}
if you want to alter the path enironment variables set the key there. You can simply add a new variable or look for an exiting one (including the value) for example with Registry.GetValue MSDN-Link
User Variables
HKEY_CURRENT_USER\Environment
System Variables
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Environment

Application not adding to startup + startup name is always "visual"

I tried adding my application to startup, if the user chooses that option. I made this code based on multiple answers on stackoverflow:
using Microsoft.Win32;
namespace Clientding
{
class Program
{
static void Main()
{
RegistryKey rkApp = Registry.CurrentUser.OpenSubKey("SOFTWARE\\Microsoft\\Windows\\CurrentVersion\\Run", true);
if (rkApp.GetValue("ItsAnApp") == null)
{
MessageBox.Show("This msgbox is to confirm that the code is being run!");
rkApp.SetValue("ItsAnApp", Application.ExecutablePath.ToString());
}
}
}
}
This does add the application to my startup list, but only with the name "Visual" which should somewhere be caused by visual express.
Also, the application doesn't actually show up on startup.
INFO:
I am running windows 8.
When adding to startup, I believe I hear the sound of a connecting device, then after 2 seconds, the disconnecting sound. I am 99% sure that this has to do with the startup program.
Any ideas why this code doesn't work?

Check the restriction that denies users to run application on the Windows start:
To restrict users from running specific Windows programs by editing the registry, follow these steps:
Click Start, and then click Run.
In the Open box, type regedit, and then click OK.
Create a DWORD value named DisallowRun. To do so:
Locate and then click the following registry key:
HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion
\Policies\Explorer
On the Edit menu, point to New, and then click DWORD Value.
Type disallowrun, and then press ENTER.
Double-click the DisallowRun value that you created in the previous
step.
Type 1 in the Value data box, and then click OK.
Create a new
HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion
\Policies\Explorer\DisallowRun subkey. To do so:
Right-click the following registry key, point to New, and then click
Key: HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion
\Policies\Explorer Type disallowrun, and then press ENTER.
For each program that you want to prevent users from running, create
a new string value in the DisallowRun subkey that you created in step
Use consecutive numbers to name the string values (starting with 1), and use the executable file name for the program as the data for
the string value.
For example, if you want to restrict users from running Microsoft Internet Explorer:
Right-click the following registry key, point to New, and then click String Value:
HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion \Policies\Explorer\DisallowRun
Type 1, and then press ENTER.
Double-click the 1 value that you created in the previous step.
Type iexplore.exe in the Value data box, and then click OK.
Quit Registry Editor, and then restart the computer.

How to pass data from windows application to web application?

I have a windows application and i want to open my web application from this windows application. My Windows application will generate a key and machine code after authorization and will save the key and machine code in to database among active users. Now i want to send this key to browser so that my web application can identify the user with his machine.
How can i do this?
i cannot use URL because the user will be able to copy the URL and use my web application from another machine. I must restrict it.
Is there any other way?

There are Two Ways to transfer winform data to web applications
If you want to transfer the data to IE then You can Use
1)MSHtml.dll
code
InternetExplorer TargetIE = null;
IHTMLDocument2 document = null;
//Check whether the IE is opened
foreach (InternetExplorer internetExplorer in new ShellWindows())
{
if (internetExplorer.Document is HTMLDocument)
{
TargetIE = internetExplorer;
break;
}
}
2) If you want to transfer data from winform to any web browser my personal advice to you please use selenium for this.
download the respective dll and driver for respective drivers from this site help
Code
using OpenQA.Selenium;
using OpenQA.Selenium.IE;
using OpenQA.Selenium.Support.UI;
using OpenQA.Selenium.Chrome;
namespace WindowsFormsChrome
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}
private void Form1_Load(object sender, EventArgs e)
{
// download the chrome driver
IWebDriver driver = new ChromeDriver(#"C:\Users\Downloads\chromedriver");
driver.Navigate().GoToUrl("http://www.yahoo.com");
IWebElement myField = driver.FindElement(By.Id("txtUserName"));
myField.SendKeys("UserName");
IWebElement myField = driver.FindElement(By.Id("txtPassword"));
myField.SendKeys("Password");
IWebElement myField = driver.FindElement(By.Id("btnLogin"));
myField.click()
}
}
}
this second part work for all browser yoou just replace chromeDriver class as per you want.
