Getting the Webhost4life Application Firewall Alert error message

Magnus Leave a comment

Well, just when I thought I was thru with strange error messages on my Webhost4life account,
I suddenly got this error message when I put up a link for download a zip-file:

 

Webhost4life Application Firewall Alert Your request triggered an alert! If you feel that you have received this page in error, please contact the administrator of this web site.

That’s not nice.

Since I previously have had success turning off their Security Guard feature,

I immediately went in to the control panel and turned it off this time also.

And it worked this time also. So if you want to have download links on your Webhost4life account, please turn off the Security Guard feature.

The well known, at least for us geek’s, technology used in the movie Minority Report, which enables one to control and manipulate the user interface with your hand movements. Perceptive Pixel showcased their technology with this video (Direct link):

Microsoft has also some ideas on how they see this technology evolve. They call it the Microsoft Surface technology.

How to data bind a ToolStripComboBox

Magnus

Normally, the ToolStripComboBox doesn’t have any properties for data binding. But you can still data bind this combobox with the method I describe here. Since the ToolStripComboBox hosts a Control that inherits from ComboBox, you can type cast to a ComboBox and do the data binding.

In this example I will bind the ToolStripComboBox to an ArrayList which consists of objects of the type ColorTypes.

So, lets get started. First create the ColorType class:

namespace WindowsFormsApplication1 
{ 
  public class ColorType 
  { 
    private int _ID;
    public int ID 
    { 
      get 
      { 
        return _ID; 
      } 
      set 
      { 
        _ID = value;
      } 
    } 
    private string _Name; 
    public string Name 
    { 
      get 
      { 
        return _Name;
      } 
      set 
      {
        _Name = value;
      } 
    } 
    public ColorType(int id, string name) 
    { 
      _ID = id; 
      _Name = name; 
    } 
  }
}

Second, in the Form that hosts the TollStripComboBox, create an ArrayList of the objects. In the Load method, cast the ToolStripComboBox to a ComboBox and do the data binding. And finally, in the SelectedIndexChanged event for the ToolStripComboBox, type cast to a ComboBox and read out the SelectedValue property.

namespace WindowsFormsApplication1
{ 
  public partial class Form1 : Form 
  { 
    private ArrayList arrListColorTypes; 
 
 
    public Form1() 
    { 
      InitializeComponent(); 
      arrListColorTypes = new ArrayList(); 
      arrListColorTypes.Add(new ColorType(0, "Red")); 
      arrListColorTypes.Add(new ColorType(1, "Green")); 
      arrListColorTypes.Add(new ColorType(2, "Blue")); 
    } 
    private void Form1_Load(object sender, EventArgs e) 
    { 
      ComboBox cb = ((ComboBox)toolStripComboBox1.Control); 
      cb.DisplayMember = "Name"; 
      cb.ValueMember = "ID"; 
      cb.DataSource = arrListColorTypes; 
    } 
    private void toolStripComboBox1_SelectedIndexChanged(object sender, EventArgs e) 
    { 
      int index = Convert.ToInt32(((ComboBox)toolStripComboBox1.Control).SelectedValue); 
      switch (index) 
      { 
        case 0: // Do the Red dance  
          break; 
        case 1: // Do the Green dance  
          break; 
        case 2: // Do the Blue dance  
          break; 
      } 
    } 
  } 
}
