You need to decide how deep your undo will go. Can the user undo the last 10 operations, or just the most recent? This decision will determine whether you store the last operation as a simple field, or as some sort of List of transactions (some sort of Queue might do, as well).

You should also normalize your transactions into some sort of model that can reflect the details of every kind of transaction supported by your application. In other words, you need a Transaction object, with fields like amount, sourceAcct, destinationAcct or however you want to do it. The point is that this Transaction object needs to be able to represent everything a user might want to do (or undo) in your program.

This Transaction object will be used to do the normal bookkeeping (adding or removing money from an account), but after the balance has been adjusted, you save the Transaction to your lastTransaction field or your transActions List.

Create a method called undo and put it in your undo handler. When the user clicks the undo button, your undo method just looks at the most recent transaction and reverses it. For example, if the transaction was a deposit of $100 to checking, when you undo it, instead of adding $100 to checking, you subtract $100 from checking. If you're working with a list of transactions, make sure you remove the Transaction after you've reversed it.

Conventional wisdom is to add source files to every header. Even if b.cpp includes only this line:

You can write a shell script, like (do not copy-paste it exactly, just to get the idea):

The reason is the INIT and FINAL part of AES in c++ code. OPENSSL command does not execute it for every encryption. So, Its performance is much higher.

Looks like it could be a simple typo:

I also had this problem before. After searching on the web I found that reinstalling NPM with Administrator permissions worked for me, as the installer without Administrator permissions doesn't create/write to some specific files. I hope this will help for you.

Pascal.

Else you could maybe try the following steps:

1. npm install dependency-check -g
2. dependency-check

Example: dependency-check ./package.json

You could check the following site for more info about it: dependecy-check

If it doesn't work, check for any path problems. Might be the case if it still doesn't work and doesn't show the message: Success! All dependencies used in the code are listed in package.json

If you're not sure if everything has been installed correctly, I would recommend a reinstall of the npm module. I made a reinstall solution for mac before: solution
