// This example requires the Chilkat API to have been previously unlocked.
// See Global Unlock Sample for sample code.

// Create a text/plain part.
loo_PtMime = create oleobject
// Use "Chilkat_9_5_0.Mime" for versions of Chilkat < 10.0.0
li_rc = loo_PtMime.ConnectToNewObject("Chilkat.Mime")
if li_rc < 0 then
    destroy loo_PtMime
    MessageBox("Error","Connecting to COM object failed")
    return
end if
loo_PtMime.SetBodyFromPlainText("This is the plain text body")
Write-Debug loo_PtMime.GetMime()
Write-Debug "****"

// The ptMime contains:
// ---------------------------------------
// 	Content-Type: text/plain
// 	Content-Transfer-Encoding: 7bit
// 
// 	This is the plain text body
// ---------------------------------------

// Start with an empty MIME object...
loo_TopLevelMime = create oleobject
// Use "Chilkat_9_5_0.Mime" for versions of Chilkat < 10.0.0
li_rc = loo_TopLevelMime.ConnectToNewObject("Chilkat.Mime")

// Initialize it to a multipart Content-Type.  We'll use multipart/mixed.
loo_TopLevelMime.NewMultipartMixed()

// Append the ptMime as a child.
loo_TopLevelMime.AppendPart(loo_PtMime)
Write-Debug loo_TopLevelMime.GetMime()
Write-Debug "****"

// The topLevelMime contains:
// --------------------------
// 	Content-Type: multipart/mixed; boundary="------------010907090104040508040404"
// 
// 	--------------010907090104040508040404
// 	Content-Type: text/plain
// 	Content-Transfer-Encoding: 7bit
// 
// 	This is the plain text body
// 	--------------010907090104040508040404--
// 

// IMPORTANT: A copy of the MIME passed in AppendPart is appended.
// Therefore, in this case, changing ptMime does not change the text/plain sub-part in topLevelMime.
// For example:
loo_PtMime.SetBody("this is the new plain text body.")
// topLevelMime is unchanged.
Write-Debug loo_TopLevelMime.GetMime()
Write-Debug "****"

// To change the content in topLevelMime, we must get the text/plain part.
// For example:
loo_PtMime2 = loo_TopLevelMime.GetPart(0)
loo_PtMime2.SetBody("this is the new plain text body.")
destroy loo_PtMime2
// Now topLevelMime is changed.
Write-Debug loo_TopLevelMime.GetMime()
