Embed Barcode Fonts for Watermark

Question

I hope someone could help me with this:
I need to add a barcode to a scanned image pdf file. This file will be viewed by a number of users on their workstations. Therefore the barcode font has to be embedded to the newly created pdf file.
I used the following VB.Net code to add the watermark:
Dim jsObj As Object
Dim SamplePDFFilePath As String = "c:\inputFile.pdf"
Dim OutputFilePath As String = "c:\outputFile.pdf"
' Create a PDDoc IAC object.
Dim pdDoc As Acrobat.CAcroPDDoc
pdDoc = CreateObject("AcroExch.PDDoc")
' Open the source PDF document
Dim rc As Integer
rc = pdDoc.Open(SamplePDFFilePath)
' Acquire the Acrobat JavaScript Object interface from the PDDoc object
jsObj = pdDoc.GetJSObject
' make a color object
Dim oColor As Object
oColor = jsObj.color.black()
' Add a text watermark.
' function prototype:
'   addWatermarkFromText(cText, nTextAlign, cFont, nFontSize, oColor, nStart, nEnd, bOnTop, bOnScreen, bOnPrint, nHorizAlign, nVertAlign, nHorizValue, nVertValue, bPercentage, nScale, bFixedPrint, nRotation, nOpacity)
jsObj.addWatermarkFromText("12345678", 1, "BarcodeFontName", 26, oColor, 0, 0, True, True, True, 0, 3, 100, -7, False, 1.0, False, 0, 1)
' save the PDF with watermarks to a new document.
rc = pdDoc.Save(1, OutputFilePath)  ' full save
This works. However the font is not embedded.
I am using Acrobat X.
My questions:
1. How to embed the barcode font to the newly created pdf file using VB code?
2. I have tried to add an additional watermark from a pdf file using this function: addWatermarkFromFile(cDIPath, nSourcePage, nStart, nEnd, bOnTop, bOnScreen, bOnPrint, nHorizAlign, nVertAlign, nHorizValue, nVertValue, bPercentage, nScale, bFixedPrint, nRotation, nOpacity). The file is a pdf containing a small graphic image. I notice after I added this image pdf as watermark, the barcode font is embedded in the new pdf file. Is this an Acrobat design? But the strange thing is that I removed the addWatermarkFromFile() function from my code and recompiled it. The graphic is not included in the new pdf file, but the font is still embedded. I wonder why Acrobat still embeds the barcode font. Is this a normal behaviour of Acrobat?
3. I have read a posting that addWatermarkAsText() function will always embed the font. But I am not able to find this function in the SDK 10. Is this function obsolete?
Any help is appreciated.

Thanks, Irosenth.
The barcode font I used is Installable. But it is not embedded.
In fact I tried adding two lines of watermarks, one using the barcode font and the other using Windows Courier font. I checked the created pdf file, both of them were not embedded.
Like I said, after I added a file using addWatermarkFromFile(), the fonts were embedded.
Also, I printed the document through the Adobe PDF printer driver, the fonts were embedded.
It looks to me that these fonts are embeddable. But they just are not embedded with the addWatermarkFromText() function.
Any further suggestions?
