VS 2008 Protect Product Obfuscation?
May 19, 2009
I've developed a product, I now want to protect it from reverse engineering and decompilation, can anyone share some info about this..?I'm looking for the BEST product out there, for doing this, I want to make it a pain to decompile or reverse engineer my product =)Does anyone know of any? or any other products that do other things that can help protect it, for example, I once found a program which converts ALL your .NET exe, into a C++ exe file, so it's not .NET code anymore, fully machine code or something like that (can't find it anymore though).
I thought posting here would be a good idea, since, a lot of you are very experienced with developing products, and perhaps some of you have used obfuscator's to protect them.

I have 2 datagrids. One to show Product information and another for Product purchase details entry. Both share the same dataset. The dataset (ds) is filled up with columns from 2 table
ProductMstrTbl : ProductID, ProductName..
ProductDetailsTbl: ProductID, PurchaseDate, Amt, BalanceQty..
DataSet(ds) : ProductID, ProductName, PurchaseDate, Amt, BalanceQty.
The problem is that: Showing from dataset or entering new records into the dataset is no problem, but am not able to save the modified dataset into DataBase. SqlCommandBuilder failed to generate the corresponding INSERT, UPDATE command as the dataset has multiple base tables.

I am looking for a free utility or way to protect my software by requiring a Product ID (Which will be created when a customer requests a paid license) to use the application after a demo version. Like most shareware apps.

I'm trying to obfuscate some VB.NET 2003 app.The resulting assemblyes are obfuscated and "run" with some errors.I cleaned all potential reflection problems, but I'm not being able to read the selected value of a combobox.
I load the Combobox using their Datasource properties, using a collection of "VTPair" (a class created by me with 2 properties: one of string type and other of object type to store the value)
This combobox handle pairs like "Male | M" or "Female | F".When trying to see what is selected, I use if mycombo1.SelectedValue = "M" then.This code, after obfuscation, throws me an exception that cannot cast type "XX" to string "M".
So, I changed the code to something more correct, explicitly casting the selected value to String:
if ctype(mycombo1.SelectedValue,string) = "M" then But the error is the same.Debugin my original code, the SelectedValue property is of type "Object" but it is a string.I tried using the ComboBox.SelectedItem property that is also an object but this time what is inside is of type "VTPair" (my own class) and then trying to access its "Value" property (which is of type Object) and trying to cast to string fails again.
Does anyone have an idea to "translate" this piece of code to work OK after Dotfucate it?

Can I change the following code and safely obfuscate it ? or that I must exclude it from obfuscating (e.g. stackoverflow 2555355 obfuscating-asp-net-dll / 2555497#2555497 )
Dim fontNames As New ArrayList
. . .
Me.myCtrlCmbFontName.DataSource = fontNames

lately, ive had a lot of free time and have been trying to password protect my flash drive in VB 2008. and ive figured out almost everything i want with it, but ive come to a bit of a roadblock. as of right now, ive got 2 accounts, but thats all ive done so far, because every account has like 3 if statements, and it would start to accumulate a bit of i made anymore. so, ive been looking into using a database, and having it retrieve the password and username from there. ive searched for hours, and have found a lot of little bits and pieces of code, but nothing that would work for my situation. Will somebody tell me how i would:
1: make sure that the password and username match in the database when i click the confirm button
2: add a new username and password to a database when they want to make their own account
3: save changes to the database when i log out and move to another computer
also, is there a simple way to log the date, time, IP address, and Username, put it in a text file, and email it to me? i would also like to know how to open a flash drive using its name, and not its letter, cause its a different drive letter on different computers.

Recently I've started experimenting with Visual Basic 2008, and just out of curiosity am trying to password protect my flash drives. (At the school I go to, it takes a couple seconds for things to disappear). So, I've got it to the point where I can have multiple "accounts" with their own passwords, ive got a lost password button, and a bunch of other stuff. But, anybody can just click out of it and go into the folder themselves, so I've been looking for a way to lock the focus on my password box. I've looked for hours and have found a lot of things that keep the focus on like a second form, so you cant go back to the first one, but I was still able to launch applications and things because the desktop was still active. I still haven't found one that keeps the focus locked on the first form and nothing else.

I am making this game where you have to protect objects from the enemy trying to capture them. I have a loop where a number is randomized from 1 to the current level the person is on. If that number is 50 then a new enemy is created and sent out to get an object. But my problem is if the level is getting higher and higher then the game will get easier and easier. I want it to get harder and harder.

I have built a deployment program (vS 2008 Standard Edition) and tried to set the Properties column to a product name and company. I have also tried leaving these blank. I'm really trying to configure my setup.exe so that it installs by default in Program FilesMyFolderName without adding a subdirectory to the path. Is there somewhere I can specify exactly the default path for my setup without it adding a subdirectory? What do I edit?

I have a datagridview that's taking a while to load because my table contains almost 5000 records. How can I provide an easy way for clients to filter the grid based on a product name. I was thinking of having labels with each alphabet on my form and when they click a label it filters the bindingsource according to the chosen alphabet. this seems like an awkward solution though.

I'm going to build a large project and want to create several libraries (DLL) for it. I don't want to merge them all in one EXE, but want to use seperate DLL files.I don't want those DLL's to be used by others, so these DLL's should be protected so that they can only be used in my own project.I was thinking of using some sort of password in the New() proc, but that doesn't work for shared classes.
Other solution I was thinking of: is it possible to check if the calling assembly has the same strong name as the DLL?These solutions are just one of my ideas. I don't know if those will work and am not saying that one of them is the way to go.What is the best approach to accomplish this?
BTW: I also use a obfuscator to protect my code.
