How do I load file in .rtf or .pdf files in vb

I will like to load .pdf file or .rtf which i have my help on it when running my vb program.
How i i go by it.

The simplest solution is to load the file into a RichTextBox control.
The plain text will be returned by the control's .Text property:

Dim sText As String

With rtfText
.FileName = "C:\Temp\Test01.rtf"
sText = .Text
End With

Private Declare Function ShellExecute Lib "shell32.dll" Alias "ShellExecuteA" (ByVal hWnd As Long, ByVal lpOperation As String, ByVal lpFile As String, ByVal lpParameters As String, ByVal lpDirectory As String, ByVal nShowCmd As Long) As Long

ShellExecute 0&, "open", fileName, "", "", vbNormalFocus

this works for me

you could alternatively consider to use the pdf.ocx ( shipped woth the reader )

just add it to your project then you can also easily print the pdf etc etc
