Hi all,
We can secure source code of business login in asp by using DLLs but how can we secure ASPX pages. I had sale a business solution to a company and they just rename the my company's name and logo and sale to other companies. any solution.

Do you have any kind of formal agreement with your clients? When you sell them an application, do you require them to sign a license agreement that prohibits what you're describing?
The truth is there isn't much that would stop an unethical individual/business from hacking a .NET application and replacing resources (e.g. a logo image) with their own. However, if you have a signed contract with them and can prove they violated the terms of the contract, your lawyer should be able to make a case in court and recover damages.

Download the deployment plugin for visual studio. Add a deployment project and use that to compile the application for deployment. In the settings you can choose to not make the site editable, which will turn all aspx files into empty placeholders and put the markup in the DLLs.

Thankx all, especialy Guffa, i will go for deployment package for aspx.
thanks alot.
keep Smiling,
Happy Coding.

If you didn't do what Guffa said ahead of time, you may be screwed.
Being that it's an ASP.NET application, they can simply replace your logo by replacing a graphic file. They could also change the HTML in the aspx page.
When a company buys an application, they usually also want rights to the source code. If that's the case, your price for source code should be a point where you are compensated enough to not care in case this happens.
If it's a generic piece of software, and not a custom built application for them and they didn't agree to the source code, you can use your receipt, and go after them for copyright infringment.

little relevant to the topic, I have seen people using utility which takes exe file as Input and generates its Source code as output ... now, what would you do there  ... Btw, I have seen it for .NET only, any info about other languages ???

Actually, that is impossible. What you have seen is someone generating source code that will recreate the program, but the original source code can not be recreated that way.
Any program can be reverse engineered like this. However, to recreate the application you have to take all the different parts of source code and try to put it together into an application igain. That takes a lot more effort and knowledge than just opening an aspx file and change some text.
You can never completely protect your program from reverse engineering, but you can at least make sure that it can't be done by someone who has just learned how to use Notepad.

Hi guys,
Anybody knows how to add a column to a datagrid?
I want to create a datagrid for database search result. However, I want to check on something with the data and show yes/no in the additional column in the datagrid according to some conditions.
Thank you
|
|
|
|
|
Probably the simplest way to handle this is to add a <TemplateColumn> to your DataGrid's <Columns> collection. You can use a custom function call within the context of a databinding epxression to display "yes" or "no" based on data in the row.
|
|
|
|
|
How do you do that? Sorry, I'm a beginner here.
Thank you
|

Well, you have to know how to work with a TemplateColumn in a DataGrid. If you Google for something like "TemplateColumn DataGrid" you'll get lots of hits to articles that will help. Here's one:
http://aspnet.4guysfromrolla.com/articles/061002-1.aspx[^]
You'll notice in the article the use of the DataBinder.Eval() expression syntax. This syntax allows for data values to be evaluated and displayed in the template column. The article shows a good example of this.
Now in your case, you want a custom function that will determine whether a "yes" or a "no" should be outputted in the additional column. For the sake of example, let's say you have a field called "TotalSales" and you want to have a column labeled "Top Seller" show "yes" when the TotalSales value is greater than 1000. Otherwise, the column shows "no". So you might create a function in your script block that looks like this:
string DisplayTopSeller(int totalSales)
{
if (totalSales > 1000)
return "yes";
else
return "no";
}Then, when defining your DataGrid, you would add a <TemplateColumn> in the <Columns> tag and use an expression that calls the DisplayTopSeller function, passing it the value of the TotalSales field:
<asp:datagrid id="myGrid" runat="server"
AutoGenerateColumns="False">
<Columns>
. . . whatever columns come first . . .
<asp:TemplateColumn HeaderText="Top Seller">
<ItemTemplate>
<%# DisplayTopSeller(Convert.ToInt32(DataBinder.Eval(Container.DataItem, "TotalSales"))) %>
</ItemTemplate>
</asp:TemplateColumn>
</Columns>
</asp:datagrid>If you are using .NET 2.0, you can substitute the shorthand Eval("TotalSales") syntax for the longer DataBinder.Eval(Container.DataItem,"TotalSales"). So in 2.0, your databinding expression could look like this:
<%# DisplayTopSeller(Convert.ToInt32(Eval("TotalSales"))) %>
I hope this is helpful.

Hi,
I have created WSE 3.0 MTOM enabled asp.net 2.0 WebService. My client(Java
Client) which has MTOM enabled on his side is sending the following soap

Hello,
I need to get a value which might be on a SQL database or Access database.
My problem is I need to know which is the database type or, even better, create a code which would work for both databases.
Anyway, first of all I am getting my connection string from Web.Config:
Dim connectionString As String = ConfigurationManager.ConnectionStrings("Conn").ConnectionString
Then, if the database is SQL I have the code:
' Define connection
Dim connection As New SqlClient.SqlConnection(connectionString)
' Define command
Dim command As New SqlClient.SqlCommand
With command
.CommandText = "GetValue"
.Connection = connection
.CommandType = CommandType.StoredProcedure
End With
' Add command parameters
With command.Parameters
.Add(New SqlClient.SqlParameter("@Culture", culture))
End With
' Execute the command
connection.Open()
Dim content As SqlClient.SqlDataReader = command.ExecuteReader
If content.Read Then
Return content.Item("Value").ToString()
Else
Return "# Undefined Value#"
End If
content.Close()
connection.Close()
If the database is Access there are a few changes just in types as follows:
' Define connection
Dim connection As New OleDb.OleDbConnection(Me.ConnectionString)
' Define command
Dim command As New OleDb.OleDbCommand
With command
.CommandText = "GetValue"
.Connection = connection
.CommandType = CommandType.StoredProcedure
End With
' Add command parameters
With command.Parameters
.Add(New OleDb.OleDbParameter("@ContentCulture", culture))
End With
' Execute the command
connection.Open()
Dim content As OleDb.OleDbDataReader = command.ExecuteReader
If content.Read Then
Return content.Item("Value").ToString()
Else
Return "# Undefined Value #"
End If
content.Close()
connection.Close()
How should I create this?
Thanks,
Miguel

Have a look at the DbProviderFactory Class:

Hi,
DropDownLists are fine when it comes to databinding or ListItems. BUT what about Both together?
For instance, DropDownList populated with all Emplyees. You will be able to select a Particular employee. And also, I would like to select an option which is "All" which is not in the Database. I have tried a few things, but cant work it out at the moment.
Thanks for any help.
|
|
|
|

Just add this after the databinding code:
ddlList.Items.Insert(0, new ListItem("text", "value"));
|
|
|
|
|
You star!
Thank you very much =D. Didn't know that I could add the items from the back end code. I was trying to add it from the Front end.
Much Appreciated.
|
|
|
|
|
No problem. Just don't try and be too clever and do something like this:
ListItem blank = new ListItem("none", "");
ddl1.items.insert(0, blank);
ddl2.items.insert(0, blank);
'cause it doesn't work too well...
