I have a little bit confusing problem. I'm not a beginner but I don't know how to do it..
For example I've written a program like notepad from which you can open files, save and etc. But when I set any custom format like ".blabla" to be opened by my app it is not working, so how can I make it to be opened by my app?
It is in WinForms
You need an entry in the registry for custom file extensions. You can try inserting a key in the registry as follows:
HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\FileExts\

Check if an executable exists in the Windows path

I am working on a WPF app, and I would like to include a button that directs it to another app. I would like it to have the following functionality:
If the app is installed on the user's computer, it opens the app for them.
If the app is not yet installed, it sends them to a link where they can download the app.
I know I will need to use Process.Start to open the app, but I am stuck on how to check if the app exists. If anyone could point me in the right direction it would be appreciated!
Two things you can use:
File.Exists(string) - Checks if the file exists.
try-catch - Simply try to open it, and handle any exceptions.
I would probably opt for the first solution...

replace the string "C:\Temp\yourname.pdf" with the path and filename for the pdf file you want to open.
This will cause the pdf to open in your systems default pdf application.
You will need: - using System.Diagnostics;

From my C# program I want to open the power options from the control panel in Windows.
However I can't seem to find out how to do that, I tried making a shortcut and see where it goes but it is referring to the control panel.
Does anyone have an idea how to do that or where the exe is located to launch?
Try the following:
System.Diagnostics.Process.Start("powercfg.cpl");
