Well, y'know on the task manager you can see all of the current processes, and it has their 'user name' (SYSTEM, LOCAL SERVICE, NETWORK SERVICE, the current user, etc.)

How do i get a program to have a different user name like SYSTEM, for example.

By launching the process as that user.

The SYSTEM process is the highest level privilege in Windows - it has more rights than Administrator. To start a program as SYSTEM you have to be extremely confident it cannot compromise, or be used to compromise, the security of your system.

How do i do that, you can do run as and whatnot, but how do you get it to be run by the system, puting the username as SYSTEM, doesnt quite work.

You can't "Run As..." SYSTEM.

You can create windows services that can run under the system account. However, the question is, what do you want to do that requires that level of priviledge? There are very few legitimate needs to run a program with that level of access.

1. I'm sorry, I don't follow you. Are you trying to encrypt the contents of the database? If so, you can a) encrypt the contents before you store them in the database and/or b) restrict access to the database.

2. Yes, you can use stored procedures from C#. http://msdn.microsoft.com/library/default.asp?url=/library/en-us/vbcon/html/vbconintroductiontodatacommandobjectsinvisualstudio.asp looks useful.

HTH. Smile | :)

Cheers,
Vikram.

Yes, you can encrypt stored procedures.

Abdul Jalil Mohamed wrote:

Yes, you can put your creation script in a SqlCommand object and ExecuteNonQuery()

Does this help?

updating a dataset using a datagrid

you can declare your SQL Stored procs using the WITH ENCRYPTION statement, this will encrypt them in SysComments and they should execute fine. I have never tried using this but i have it on good authority that it works.

Using WMI for SQL server you should be able to create stored procedures; create a management object and the execute your SP text using it.

How can I open a web page(url string) from a web forms button that I've placed on my web.aspx application?

Re: web development with c#

Anthony Mushrow7-Dec-05 23:01

Re: web development with c#

7-Dec-05 23:01

Well you can do:

this.Response.Redirect(name of web page / file to download etc)

or

this.Server.Transfer(url or whatever - will not work when linking to a file for downloading etc.)

The first one is better, but with the second, it doesnt change the url in the address bar on the browser so if you wanted to keep the full url a secret...

Thank you!

this.Response.Redirect(name of web page) works well, but I need it to open in its own window.
I think my prasing was incorrect...

Can anyone help me take a look at my code?

8-Dec-05 8:18

Well, i asked that a short while back as well, you'll have to use a html button and in the onclick bit put:

window.open("website url","one_word_id_type_thing","resizable=0,width=550,height=400")

resizable=0 means you cant resize it 1 means that you can.

Just thought, to open a page in a new window, and keep the web forms button, add:

using System.Diagnostics;

then in the button put:

Process.Start("website url");

that should open it in a new window.

I have tried butit seem like is not working. Below is the code, could anyone help me with it as i'm totally lost?? Thanks!! The code:

private void Radcalendar2_SelectionChanged(object sender, System.EventArgs e)

I'm sorry to say this, but your question is not very clear. Is English not your native language?

Here's what I *think* the problem is:
If you have a DateTime value, do NOT use the ToLongDateString() method as it formats the date depending on the user's Windows settings. Rather, use DateTime.ToString("yyyy-MM-dd") or whatever format the database accepts the date string in.

HTH. Smile | :)

Cheers,
Vikram.

Hi, Vikram.. Thanks for replying.. Actually, maybe what i explained is not very clear to you.. But actually, what i wants to do is that i've create a calendar and what i need to do now is that when i click on the date i've select it will show out the database of the user.. Is it clearer for you. As you've mention earlier on that i shouldn't write the ToLongDateString() if i using DateTime.ToString().. Can i ask you, then now how should i write the code so that it'll show out the database when i click on the date. Thanks!!

Cheers!

What do you mean by 'database of the user'?

Let's say you want to retrieve all the details of employees who joined on a certain date, from a table Employee. Assume that the user chose the date 01 Sept 2004, and that it is contained in the DateTime value userDate. Your query should look like:

string selectQuery = "SELECT * FROM Employees WHERE JoiningDate='" + userDate.ToString("yyyy-MM-dd") + "'";

Of course, the details will differ in your application, but you should get the general idea. Smile | :)

Cheers,
Vikram.

Well done, the OP was actually using paramaterized queries and you just taught him how to introduce Sql Injection attacks to his code.

Jamie, I took a look at your reply below and it's interesting - I didn't know that parameters are automatically converted at runtime. Thanks!

But what do you mean by 'introducing SQL injection attacks'? Confused | :confused:

Cheers,
Vikram.
