Jul 3, 2010
We are developing an application in VB.NET 2008. We break the application into smaller multiple dlls so that we can easily update the program at the customer end.We want to know that is their any way to stop the other person to use my dll in their application?i.e we want to lock the dlls such a way that the dlls will be used by us only and not anybody in their application.Also we want to block viewing of dlls code using any code reflector

I am trying to find a way to write a modular application.In this application there is a main form. Each module will be contained in one (or more) dlls. The idea is that a dll module can be dropped into the module folder and the application will be able to pick it up without the application having any prior knowledge of the dll existence.

I am trying to create an interface between a third party application which can make use of C/C++ DLLs, but no interface directly to .NET. What I was hoping to accomplish (not sure if possible though), is create a very basic C++ DLL (not .NET), which the third party application would call directly. This DLL would contain a basic method such as "DoSomething()". Somehow, from my .NET application, I want to "listen" to this DLL and "takeover" the DoSomething() method, and then returning the result back to the DLL, which will in turn return the result back to the calling third party application.
I don't even know if this is possible because I'm sure I would somehow have to get a hold of the memory space of the DLL as initiated by the third party application. Also, it seems that creating a managed DLL does not work, based on feedback from other individuals who have tried this.

I am building a database application using MYSQL as the backend. The MYSQL instance will be installed remotely on a share host. I have access to SSL certificates. I'm obviously not looking for any code but, conceptually, how do I go about securing the connection using SSL between my application and the remote MYSQL database?

I've made an application and it connects to my database. But the issue is the details of the database can be found out through packet logging or something. How can I stop this from happening and secure it, without having to have a third party such as PHP script etc.

How do I make it such that when John's name is selected in list view, John's age is automatically displayed in the text box?
And when Kat's name is selected in list view, Kat's age is automatically displayed in the text box?

I'm trying to make a application that allows the person to script config files for an open game server project so they don't have to do it manually... I'm starting with 3 groups. Those groups are "NPC NAMES", "MONSTER NAMES", and "MONSTER WALK POSITIONS"... I want the user to be able to add as many items to the group as they want... Right now I'm using a listbox, but its very messy... I want the user to be able to add items to these groups, and then add the items of each group to a .txt file.

I am trying to understand how to interact with external DLLs written in C++ for use in my VB.NET application. I have some DLLs that a client wrote that do some math functions. Everything was working on a 32-bit machine. Because we were taxing the 32-bit machine we moved to 64-bit. Now we can't get the same functions to work. The DLLs were re-compiled as 64-bit DLLs and they still don't work. So my client wrote some dummy DLLs to see if we could figure out the problem. Here are the "signatures" of the DLL calls that I am making:[code]....Ultimately I would like to get to calling initialize_quiet and I am guessing at the format of the marshalling, const size etc.

I have developed a couple of windows applications in Visual Vasic Express 2008. To my horror, I have just discoved that the Setup Project is not available in the express edition.I have been searching to discover which DLLs I will need to include when using my 3rd party Deployment Application.
I know which ones I need for my 3rd Party Controls, but am stuck on which Microsoft DLLs will be needed the Microsoft Controls I have used, plus any other Common DLLs that are always needed.
I have tried searching Microsoft's site but without success.

Create an application that allows the user to select or enter into a combo box the number of days a person will work, and calculates the total amount of pay she will receive over that period of time. Salary is one penny the first day, two pennies the second day, four pennies the third say, and continuing to double each day.
The combo box must list the following items: 30, 180, 365, and 1000. Must be the default drop down box. Use a validating event procedure on the combo box.
The program should go through a loop once for each day, doubling the number of pennies with each iteration of the loop. You will need a running totl of the number of pennies that you add to with each iteration. To calculate the total amount of pay, multiply the total number of pennies by .01 and show the result in currency format.
Public Class Form1
Private Sub ComboBox1_SelectedIndexChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles ComboBox1.SelectedIndexChanged

The fact is I'm making an application, which users can install by using a Setup file...once installed the data in the database can be updated by a centralized server. To do this, they can insert a DVD/CD-ROM and export the necessary data towards it. I need to do it that way, because some of the users who really need this data will be using stand alone computers.The application gets it's data from a mdb-file and the connection remains open as long a person works with the application (maybe not the best way to do, but I know :-) )...when the user uses the application, he can perform an export...this exports the .ini-file and pictures (which works fine), but he also needs to export the mdb behind the application...I already tried connection.close() before and connection.open() after the System.IO.File.Copy...but that doesn't seems to work.

I have a document management system, and I am building a Web-Service interfaces to the database.Everything works so far, just that right now, it's totally unsecured, everybody can access it.How can I incorporate password or private-public key authentication?
I can only find 'best practises' and using 'windows user' or passport authentication.But I need authentication from a user and password stored in the database, or better for an RSA private-key stored for each web-service user in the database...

I am aware of the many cryptography providers that are available in the .NET framework along with the basics of how to use them. This is simple enough.
But my concern is this.Lets say I want to use these libraries to encrypt XML serialized objects to prevent tampering and the ability of anyone to come along and view the contents of these files.
The problem that I am always left with is that the key to decrypt this data would need to be stored as a constant somewhere in my application. Essentially rendering the entire exercise pointless.
So, how does one store a key for an encryption algorithm securely inside of a disassemblable application?
EDIT: So If I am understanding both answers below correctly. What this means is that essentially any implementation (to be secure) requires it to be readonly or writeonly but never both? Is this correct?

I have created a security program that monitors the keystokeswebsitesprocesses... I want to FIRST ask if this is a legal question; for, my purpose in this program is security reasons (eg. following up on employees to make sure that they are doing what they are paid to do. They all know this is running, and have been warned not to go to sites and enter information they do not want reviewed).
Second, I want this program to be hidden so that techy persons cannot go into task manager and end the process, then go on to some porn site! How could I make this app hidden, or at the very least make it 'un-end-able' from the task manager?

I have a windows forms application that has no form and it runs in the background. It using a webbrowser control to get information off the internet.The program is that when I add the event handler:webbrowser.documentcompleted the program just shuts down. If i put a message box after the event handler then it works just fine because the webrowser has time to load the document. How can I do some like console.readkey that you would do in a console application?
