I have some libraries and apps written in C++/CLI and C#, and I'd like to obfuscate/protect the source somehow. I've seen a lot of you say how it's a waste of time, and I know there's no silver bullet here. I'm not looking to make it impossible to decompile my software, just more difficult. In particular, I'd like my source to be un-viewable with .NET Reflector and other similar tools. Reflector makes it dead easy to decompile .NET apps, and any developer with 1/1000 of a brain could figure it out. If someone really wants to decompile my code, they should at least have 3/4 of a brain 
I read a thread here awhile back about code protection and saw someone recommend .NET Reactor[^]. I've been experimenting with the trial and so far it seems to do what I want - I can't view the implementation of any functions, and the names of all my private members and functions come up as non-printable characters. However, I can still plainly see all the class and public function and property names (but not their implementations). I'd like to obfuscate everything, including all public information, but if I do that, then any app that tries to use the protected library throws a TypeLoad exception (or something like that). I tried emailing their support a couple of days ago, but I haven't heard back yet. Has anyone had any luck with .NET Reactor?
Or, if anyone knows of a better tool with a decent price tag (free / open source is always great  ), I'm open to alternatives.
Thanks,
Dybs

Xenocode definitely looks like a great tool (especially being able to integrate the .NET Framework components into the binary), but it's a bit pricey for us. If anyone knows of something under $1000, that would be great. It's hard to compete with .NET Reactor's price tag of only $280 for a company-wide license. Or is this a case of "you get what you pay for"?
Thanks,
Dybs

I've write code two style but the same function on my application (Window Application)
1- my form has been load data from table in database in to DataTable and bind dataTable to dataGridView Controls.
in this form need to do any function like insert delete update query..
style one:===================================================================
Public Shared Sub addNewProduct(ByVal p As product)
Try
cmdAddProduct.CommandType = CommandType.StoredProcedure
cmdAddProduct.CommandText = "NewProduct"
cmdAddProduct.Connection = database.cn
With cmdAddProduct.Parameters
.Add("@PCode", SqlDbType.VarChar, 20).Value = p.ProductCode
.Add("@BCode", SqlDbType.VarChar, 30).Value = p.BarCode
.Add("@Des", SqlDbType.VarChar, 50).Value = p.Description
.Add("@Unit", SqlDbType.Int).Value = p.Unit
.Add("@UnitPrice", SqlDbType.Float).Value = p.UnitPrice
.Add("@Stock", SqlDbType.Int).Value = p.StockBalance
.Add("@photo", SqlDbType.Binary).Value = p.Photo
.Add("@sms", SqlDbType.VarChar, 50).Direction = ParameterDirection.Output
End With
cmdAddProduct.ExecuteNonQuery()
cmdAddProduct.Dispose()
Catch ex As Exception
Throw ex
End Try
End Sub=======================================================================
for example style two=========================================================
internal static void Add(Customer value)
{
try
{
//data is dataTable
DataRow row = data.NewRow();
row[0] = Customers.NextID();
row[1] = value.name;
row[2] = value.ssn ;
row[3] = value.phone ;
row[4] = value.address ;
data.Rows.Add(row);
da.Update(data);
}
catch (SqlException) { throw; }
}
Could you tell me which one is better for working with biggest database?

I'd vote for the first one. The reason is that a DataTable loads all rows into memory, whilst the first one just creates a command and executes that.

You may find that you get more help if you form your question clearer, and with a little more humility. While I appreciate that English may not be your first language, this reads like a command and we aren't here to serve you - a "please" wouldn't go amiss.

Stick around. We'll help. Most of us are pretty decent people, and none of us (that I know of) has any grudge against "foreigners." Given the international membership, we're all foreigners somewhere. Over the years I've seen many members drastically improve their English skills by posting questions, answering questions, and asking for clarifications. The only way to learn a language - even non-computer languages - is to use it often, and to associate with people who know it better than you.
As a start, let me rephrase your post:
"My English is very poor. Actually I am humble. Please try to understand me.
This question has been resolved. Thanks to all of you.
I think I should improve my English."
Good luck, and welcome to the best collection of intelligent people I've ever found on the Internet.

I have been going over most of the examples (in VB .NET) on the internet on the produtcion of an RTD server and I have managed to create the server and publish data across the network, but I cannot figure out how the client would publish data back to the server for other clients to obtain. Any help would be greatly appreciated.
Thanks

I know noone has replied yet, but I still live in hope. Does anyone know the equivalent of getting data from an excel cell to be published via RTD. Basically I want the equivilent to DDE from VB6 (code bellow) where the windows form textbox can be linked to the cell. Since DDE is not supprted anymore, I am looking to replace the code. Any help would be greatly appreciated:
Text1.LinkMode = 0
Text1.LinkTopic = "Excel|MyBook.xls"
Text1.LinkItem = "R1C1:R2C3"
Text1.LinkMode = 1
'Poke the text in Text1 to the R1C1:R2C3 in MyBook.xls
Text1.Text = "one" & vbTab & "two" & vbTab & "three" & vbCr & _
"four" & vbTab & "five" & vbTab & "six"
Text1.LinkPoke()
'Execute commands to select cell A1 (same as R1C1) and change the font
'format
Text1.LinkExecute("[SELECT(""R1C1"")]")
Text1.LinkExecute("[FONT.PROPERTIES(""Times New Roman"",""Bold"",10)]")
'Terminate the DDE communication
Text1.LinkMode = 0

I have an issue with command builder
below is the code
Public Structure SearchandUpdateClaimDetail
Private cnConnection As System.Data.SqlClient.SqlConnection
Private cmdCommand As System.Data.SqlClient.SqlCommand
Private adAdapter As System.Data.SqlClient.SqlDataAdapter
Private ds As System.Data.DataTable
Sub New(ByVal ConnectionString As String)
cnConnection = New SqlClient.SqlConnection(connectionstring)
cmdCommand = New SqlClient.SqlCommand
adAdapter = New SqlClient.SqlDataAdapter
ds = New DataTable
End Sub
Public Function SearchClaimDetail(ByVal SearchQuery As String) As DataTable
ds.Clear()
cmdCommand.Connection = cnConnection
cmdCommand.CommandText = SearchQuery
adAdapter.SelectCommand = cmdCommand
adAdapter.Fill(ds)
cnConnection.Close()
Return ds
End Function
Public Function UpdateClaimDetail(ByVal DTTable As DataTable) As Boolean
Dim sqcmdb As New SqlClient.SqlCommandBuilder(adAdapter)
adAdapter.Update(dttable)
cnConnection.Close()
Return True
End Function
End Structure
this structure is in a class. i call this structure (function SearchClaimDetail) in another class (BLL) which exposes its function to GUI which binds the grid.
Now when i modify the datatable and sends it back (function UpdateClaimDetail)to update the database it goes smoothly but does not update the database nor it gives any error. There is one primary key in the table which is used in the select command.
How can i update the table. I do not want to insert the rows but to update existing rows.

You can use WiX[^] to make the installation packages (requires some learning). Or you can use other programs to do so, some are free and others are not.
If you want to create a bootstrapper, you can use MSBuild (included in the .net framework) or use other bootstrapper generators.
