Add partially bolded text to a richtextbox in vb.net

I am using a Rich Text Box as a display log for my program. The program preforms a mass copy of one directory from a source machine to multiple target machines. I wish to bold the computer name as added to the the text box as I add the lines. I currently add the lines as follows:

rtbStatusLog.AppendText(My.Computer.Clock.LocalTime.ToString + " " + TargetName + ": File Copied: " + destinationFileName + vbCrLf)

I need the "Target Name" variable, and subsequent: to be bold, but nothing else.

I also wish to do this as the lines are added if possible instead of selecting the results at the end and bolding them.

A rich text box has a property called SelectionFont. Setting attributes of this property changes the way the text is shown.

So do it like this:

Dim currentFont As System.Drawing.Font = rtbStatusLog.SelectionFont
Dim newFontStyle As System.Drawing.FontStyle

rtbStatusLog.SelectedText = My.Computer.Clock.LocalTime.ToString
rtbStatusLog.SelectionFont = New Font(currentFont.FontFamily,currentFont.Size,newFontStyle) 
rtbStatusLog.SelectedText = " " + TargetName + ": File Copied: " + destinationFileName + vbCrLf)

When you change the SelectedText property you are actually writing to the box.
