Ruby Blog

I've decided to create a Ruby only blog, though I'll keep cross posting here for now...who knows, I may change my mind and just keep the one blog here...

Viewing .CHM files on Mac OS X - Chmox

I tried several Mac options and had no luck (xchm froze, libchmxx has a utility called chmdissect - it worked, but no images)...finally, I struck gold with Chmox.

1) Install CHMLIB - http://www.jedrea.com/chmlib/

% ./configure
% make
% sudo make install

2) Install Chmox - http://chmox.sourceforge.net/

The binary is a standard dmg file...click on the dmg file and move the application over to your application directory.

Sending E-mail with Ruby Net::SMTP

All you need to know is here:
http://www.ruby-doc.org/stdlib/libdoc/net/smtp/rdoc/classes/Net/SMTP.html

def send_email(from, from_alias, to, to_alias, subject, message)

  msg = <<EOF
From: #{from_alias} <#{from}>
To: #{to_alias} <#{to}>
Subject: #{subject}
 
#{message}
EOF

  Net::SMTP.start('localhost') do |smtp|
    smtp.send_message(msg, from, to)
  end
 
end

Or if your mail server is on another machine:

  Net::SMTP.start(mail_server, port, helo_domain) do |smtp|
    smtp.send_message msg, from, to
  end

For example:

smtp.send_message('your.smtp.server', 25, 'mail.from.domain')

ASP.NET Calendar Control - Misc

How to: Display Selected Dates from a Database in the Calendar Control

Hide days that aren't in current month:

protected void Calendar1_DayRender(object sender, DayRenderEventArgs e)
{
    if (e.Day.Date.Month != Calendar1.VisibleDate.Month)
    e.Cell.Text = "";
}

Disable link for particular day (the 23rd, in this case):

protected void cal_DayRender(object source, DayRenderEventArgs e)
{
    if (e.Day.Date.Day == 23)
    {
        e.Cell.Controls.Clear();
        e.Cell.Text = e.Day.DayNumberText; 
        e.Cell.BackColor = System.Drawing.Color.Gainsboro;
    }
}

ASP.NET HyperLink Control: mailto link

<asp:HyperLink ID="EmailLink" text='<%# Eval("UserEmail") %>' NavigateUrl='<%# Eval("UserEmail","mailto:{0}")%>' runat="server" target="_blank" />

With a "Subject"

<asp:HyperLink ID="EmailLink" text='<%# Eval("UserEmail") %>' NavigateUrl='<%# Eval("UserEmail","mailto:{0}?Subject=YourQuestion")%>' runat="server" target="_blank" />

Identify Button Clicked in GridView

I had a GridView with a ButtonField used to Select a record to display a User's details in a DetailsView. I wanted a second button to display different form for changing a Users's password, since I wanted that to be a separate option.

GridView (usersGrid):

<asp:ButtonField CommandName="Select" Text="Select" />
<asp:TemplateField>
    <ItemTemplate>
        <asp:LinkButton runat="server" ID="changePasswordButton" Text="Change Password" OnClick="usersGrid_SelectRow" />
    </ItemTemplate>
</asp:TemplateFild>

Code Behind:

protected void usersGrid_SelectRow(object sender, EventArgs e)
{
    GridViewRow row = (GridViewRow)((LinkButton)sender).Parent.Parent;
    usersGrid.SelectedIndex = row.RowIndex;

    MyDatabase.DBUtil = new MyDatabase.DBUtil();
    changePasswordDetails.DataSource = DB.GetUser(Int16.Parse(usersGrid.SelectedValue.ToString());
    changePasswordDetails.ChangeMode(DetailsViewMode.ReadOnly);
    userDeatils.Visible = false;
    changePasswordDetails.Visible = true;
    changePasswordDetails.DataKeyNames = new string[] { "UserID" };
    changePasswordDetails.DataBind();
}
