View 1 RepliesWhat I've decided to start working on is pretty much a personal project but something I may use in my UNI course in due time. I'm creating a security program with a set of access codes (yes I am a bit of a star trek fan) - 4 in total to be exact. I want to be able to use an Encrypted key file in form of a simple notepad created text file to update the codes at any due time. All I'm looking to do is write the access codes to the text file (say for a friend to use the program), Encrypt the file through the program and be able to also decrypt to obtain the new access codes on demand also via the same program. Once decrypted the codes can be read and verified if the user has entered each one correctly. I could hard code the access codes into the program but would rather do it the way I've thought of.
Back in the days of the old VB6 there was a simple method but for some reason that doesnt work any more. What I guess I'm looking to do is have 4 text fields where 4 digit access codes are typed into, have the program take them and encrypt each one is then written to the text file. Hoping that will make it a bit clearer what I'm trying to achieve as I think I made it sound like I want to encrypt the text file after the info has been written to it, which is of course one option so wouldn't mind know how to do that too!
I am trying and failing to make a text encryption and decryption program. How can I encrypt and decrypt text or text files?

View 2 RepliesIf a use the NPV() function in Excel (2010) with a discount rate of 5% and 10 cells that each contain 505,000 the resulting NPV function call "=NPV(5%,C2:C11)" returns the value of 3,899,496.
If I use the Financial.NPV() method in the Microsoft.VisualBasic namespace (in my C# application) and pass in a discount rate of 5% (as a double) and an array of 10 doubles with a value of 505,000 each, the VB function returns the much lower value of 100,999.99 (plus a few more decimals).
When I do a
Request.Querystring("key1")
Request.Querystring("key2")
The system doesn't seem to parse the second ?/value out but treats it as if key1 was all one string, e.g. [URL] ...as if it completely ignores or doesn't parse out the second (or other if more) key/value pairs.
Need to return the greater of 3 values. Each value is based on user input and system calculations. Requirement = the greater of (Req1, Req2, Req3) Have tried a number of "If" "Else" and Ifs within Ifs "<" and ">" combinations without consistant results. This may seem simple to some but I am relatively new to VB. My search on MSDN was not fruitful.

View 3 RepliesI have set up a method in vb.net and in xcode for encrypting a string using as far as i can tell the same parameters for an AES encryption.I've looked all over the place but cannot find information on whether they use the same encryption algorithm and settings.
this is the vb.net code:
Dim encryptAES As New AesCryptoServiceProvider()
Dim encoding As New UTF8Encoding()
Dim encryptor As ICryptoTransform
encryptAES.Key = encoding.GetBytes("12345678901234567890123456789032")
encryptAES.IV = encoding.GetBytes("1234567890123416")

View 2 RepliesWhat I need to do is to have my program look at 2 different values then return a value.
Here's an example:
If my tube material = SA-214 and the tube gauge = 20 then my tube wall thickness = .032. The thing is I have 5 different types of tube material and 12 different tube gauges so based on which tube material is selected and which tube gauge is selected the tube wall thickness will vary. So if I select a TM of SA214 and a TG of 14 then my tube wall will be .076.
Is it possible to make a function that returns both a datatable AND a list(of custom class) at the same?In my GUI layer, the main form (the application is MDI) calls this function and it has to fill the datagrid on one of its child forms and it also has to fill lot of other child forms with various information that is calculated from my custom class properties.Both the datatable and the class properties are created from the same external database and that's why I don't want to have two separate functions.
