Crazy piece of code: Checking query parameter

Posted by Dmytro Shteflyuk on under ASP.NET

How often you are laughing out loud when looking on the someone’s code? Today I found great code in my current project and I can’t hold posting this to my blog. So,

if (Request.QueryString.HasKeys())
{
    string[] keys = Request.QueryString.AllKeys;
    foreach (string k in keys)
    {
        if (k == "memberpagemode" && (string)Request.QueryString.GetValues(k).GetValue(0) == "edit")
        {
            pSett.ChangeFormViewMode(FormViewMode.Edit);
        }
    }
}

And how do you search through the hash for a key with specified value?

// Compute the MD5 hash of the signature builder
hash = md5.ComputeHash(Encoding.Default.GetBytes(

Generating content for the Facebook’s setFBML method in ASP.NET

Posted by Dmytro Shteflyuk on under ASP.NET

In my current project we decided to build a Facebook application. This is really great platform with many interesting ideas inside, which usually means that you will spend a much time to make your application working as expected. Today I wanna talk about user profiles. Any Facebook application could add some action links, which will be displayed under the user’s picture, and some content for wide or narrow column.
