Hello all,
I'm having some headache with my project references.
First off all, I have a common library which uses 3rd party .NET librarys. Now, the problem is that all these 3rd party dll's come from one program that needs to be installed on the system for my application to work. But still, vs2010 copys the dll's into it's output directory and uses those copys instead of the dll's located in the program folder of the 3rd party program. (Are you with me, I know my english isn't top of the notch) How can I prevent this, so that vs2010 doesn't copys those dll's again, and that my app will use the original dll's?
Is it possible?
The next problem I have, is that in my application, I use a usercontrol from my library that uses a 3rd party dll. And for some reason I really need to add that 3rd party dll to my application references allthough my library already references that 3rd party dll. Can I change this behaviour? So that referenced dll's from my library don't need to be referenced in my application itself?
I hope that my questions are clear,
Thanks in advance!

Thanks! This sounds really helpfull 
I have a question though, Say that I use this approach and on my development machine I have V1 of the 3rd party libraries, but on the customers machine, V2 of the 3rd party libraries are installed. Will that cause problems? (Let's presume the API is the same, the new version has only bug fixes and other enhancements)
Because now I have a bindingredirect of a 3rd party dll in my app.config, that says, whatever version you think you need, use V1.
Can this be changed to: Whatever version you think you need, use the version installed on this system?

As far as I am aware, It will happily use what ever version of the 3rd partly library that is installed at that location. But you have to make sure that the functionality is available in the libraries that are installed on the local PC.

I was tasked in my schooling with adding security features to a calculator code we wrote for a previous project. I have never used security features before and have not the first idea how to incorporate them in my project. We apparently have to add them to our functions (plus, minus, multiply, divide). I'm not asking for anyone to do the work for me but I could use help with what exactly needs to be done.
The following is an example of the code for the button that divides:
Private Sub Button4_Click(sender As Object, e As EventArgs) Handles divNum.Click
ansBox.Text = (Integer.Parse(numBox1.Text) / Integer.Parse(numBox2.Text)).ToString()
End Sub
If more of the program is needed or anything just let me know. Any help would be amazing!

What do you mean by "security features"?

Here is my teachers exact wording of the assignment.
The GUI interface for your calculator now needs additional functions. To add security functions address the following in your Visual Studio file:
Program at least one of the functions (add, subtract, multiple or divide) in your calculator program to include a security feature.
An example of a security feature is to declare a variable as "private" as opposed to "public" (conduct some independent research if necessary to refresh on these topics).

Other than being in VB instead of c# I don't see anything to change in the code you've shown. 
Seriously:
From the wording, it looks like the issue is the accessibility of the various variables and methods in the implementation of your program. Make sure everything has the most restrictive accessibility (public/internal/protected/private) that still allows it to function correctly. Then look at things that aren't private and think about how you could redesign your code to reduce their "exposure".
I'd suggest you avoid modifying the accessibility of any code generated by the designer, lest you confuse the designer.

As Matt says, this has nothing to do with security; it's a pity your teacher does not understand that.
Use the best guess

He left this piece of python code as an example for the assignment but idk where in the code it has the security feature. From everything I have found all of my code says private on it so if that's what he wants it should have been already done lol
