Re: Code Obfuscation

ssware — Mon, 07 Dec 2009 05:00:00 GMT

Use an obfuscator such as Crypto Obfuscator (http://www.ssware.com/cryptoobfuscator/obfuscator-net.htm) which uses various layers of protections such as string encryption, symbol renaming, control flow obfuscation, resource protection, assembly compression, encryption, anti-decompiler, anti-ILDASM, etc, etc. All this combine to make it
extremely hard to decompile your assembly.

Re: How to count Page_Loads and check if there's data in a table

markgr26@hotmail.com — Mon, 07 Dec 2009 05:00:00 GMT

It looks like you do know how to query the database because you're using SqlConnection and SqlCommand in the code snippet you posted originally.

You need to look at some basic T-Sql skills for querying data. Get your query in a stored proc (if you're using Stored Procs to query) and execute Stored Proc using SqlCommand. Read up about the SqlCommand.ExecScalar() method - this will prob. be useful to you.

Re: How to retrieve page URL

markgr26@hotmail.com — Mon, 07 Dec 2009 05:00:00 GMT

Here are a few useful properties of Request object. You will find that some of the values are duplicated between properties - do some googling and you will find more. Knock up a test web page and output all these values. It's useful info.

        Request.PhysicalPath;
        Request.RawUrl;
        
        Request.Url.OriginalString;
        Request.Url.PathAndQuery;
        Request.Url.Query;
        Request.Url.Port;
        Request.Url.Scheme;
        Request.Url.IsLoopback;
        Request.Url.AbsolutePath;
        Request.Url.AbsoluteUri;

Also, if you do ever need to find out which control posted back then this seems to do the trick:

        public static Control GetPostBackControl(Page page) {
            Control ctrl = null;
            string et = page.Request.Params.Get("__EVENTTARGET");
            if (!string.IsNullOrEmpty(et)) {
                ctrl = page.FindControl(et);
            } else {
                foreach (string ctl in page.Request.Form) {
                    Control c = page.FindControl(ctl);
                    if (c is System.Web.UI.WebControls.Button) {
                        ctrl = c;
                        break;
                    }
                }
            }
            return ctrl;
        }

Check "Allow this precompiled website to be updateable" on your project settings.
For added security, obfuscate the resulting dll(s) using an obfuscator such as Crypto Obfuscator (http://www.ssware.com/cryptoobfuscator/obfuscator-net.htm).
