Call another C# Program & pass parameters to bypass startup form

Question

Good day,  I need help.
1. I would like to open up another C# program onclick of button.
2. The other program i wantt to call has the same startup form that the one I'm calling from, how do i bypass the startup form of the program i'm calling with right parameter logins.
3. When trying to call the program from a location i get errors on the path: this seems to work "i:\\app\\test" but if i try this then error: "i:\\app\\test i:\\app\\startup.ini 1" - if i run the location then it's fine "i:\app\test i:\app\startup.ini 1"
Please Assist! Regards

hi,
I want ot take master billa's answer further to clear out few issues:
1.
In the article the person creates a method called IsCritical() to check the throwed exception type. Instead of creating a new method called "IsCritical()" cant we write the super type exception (therefore from the BLL) it throws the super type exception that we can drill down to find out the inner type in the Controller or in the VIew of MVC?
2.
When the person uses a sperepate method IsCritical() to check the inner type of the exception, the class consist of so many error handling methods (in my case) .... becuase i already have two methods that throws exceptions and one method that decides what exception to throw and now adding a another to check the inner type makes the class lengthy, is this a good practise?
cheers

well my friend, there are many ways to handle exceptions.

my way was always to handle exceptions in their scope. meaning that you have a try catch on the block you handle, and never throw the exception up to the higher level unless its a basic error that is a must be handled on application scope since without that  information you cant continue to next steps

Hi


I think there is no issues, you can throw in base method and catch in top level and make as user friendly message  and then display to user.
