Make.net Function Secure On Web?
Apr 6, 2011
I have a VB.Net exe application that has a function in it that contains my encryption method that is used through out my application. This function is used to generate all my encrypted passwords and files etc. therefore for obvious reasons I do not want this to be visible to end users. In my application this is fine as it is compiled as a .exe. However I want to now create a ASP.Net web based version of my application.
Now here comes the question, if I was to create a web version of my application then this function would be visible to the end users along with a large number of other functions that if edited could bypass security and license control.I would like to know what is the best way to keep my ASP.Net webbased version secure from tampering, or is ASP.Net not the best for this?

I don't want my programs to be cracked. I have this simple authorization system that prompts my users to enter their forum credentials (I have a forum and the users must be registered members to use the programs).So I made a php script that will take in 3 strings sent in by my applications and it will check against the database if that user exists and is of the proper group and it will display a message on the page and my application then looks for the response in the page source which says if this particular user is allowed to use the program or not.

i wanted to ask how to make picturebox1 ,to which functions are already assigned, perform the same function as picturebox2 ,to which no functions are assigned.For example:I have already made picturebox1 and have assigned it alot of function like when play button is pressed then picturebox1.visible = true and when we press pause button picturebox1.visible = false. So now i decided to make a theme and have to remove the picturebox1 and want to allow the picturebox2 to havefunction of picturebox1.But when i disable the theme the function of picturebox1 should go back to picturebox1.

I have some functions in my VB.NET DLL which I can 'hide' from my VB6 app by using the following: <Runtime.InteropServices.ComVisible(False)> But is there a way to make a function ONLY visible to COM clients and not to .NET assemblies? This way I can use Shared methods for the .NET side avoiding the need for an instance declaration.

I just started learning visual basic in VB 2005 express today, and the only other programming language I have used is AutoIt. Now in Autoit there is a function called "pixelsearch" where it allows you to specify a color, and coordinates left, top, right, bottom to search for a pixel that matches the specified color Example:$psearch = pixelsearch(0, 50, 100, 75, 16172309)

I can create classes that use generics, however I was wondering if it is possible to apply this to a shared method rather than rely on the caller casting to the correct type.This is the method:
Public Shared Function DeserializeObject(ByVal serializedXml As String, ByVal givenType As System.Type) As Object
Dim serializer As New XmlSerializer(givenType)
Return serializer.Deserialize(New IO.StringReader(serializedXml))
End Function
I'm pretty sure this can't be done, but thought I'd check (if so Extra points will be awarded if someone can technically explain why the compiler can't do this)..

My boss has just asked me to make an "Update Program Function" for our program.My program is being used by someone in my company. The database is put on server computer.At the present, my program run by some dll file, and when I fix or update the source code, i will compile to dll and put it on the server disk. After that, the users will go to this server disk and copy the new dll and overwrite the old dll in their client computer.
Now my boss asked me to make an "Update Program Function" : before the user login, the program will check the version (or the creation date) of the dll in the server disk, if it newer than the current dll, the program will update the new dll, else the program login normally How can i do that?

What is best practice for securing DLL's for projects you are working on? Certain DLL's I am interested in developing will have data access layer (DAL) and business logic layer (BLL) functionality. There may be several apps that can eventually hit these DLL's to perform business specific functions. What is the best way to secure these DLL's so they can only be used by only creator's applications?Security for both blocking unauthorized use of the DLL's and security against possible decompilation are both desirable.
