Hi,

I have a program that performs mail merges (using TX Text Control) - which then prints letters and envelopes.

I'd like to be able to send the envelopes to the "Upper" or "Manual" tray of the printer.

There is a combobox on the form that is populated with the PaperSources available for the default printer (i.e. "Upper", "Lower", "Manual", etc.)

I want to be able to have the item print to the appropriate paper source based on the selection made by the user:

Dim myPrintDocument As New System.Drawing.Printing.PrintDocument

myPrintDocument.PrinterSettings.FromPage = 1
myPrintDocument.PrinterSettings.ToPage = 1

'print in Portrait mode
myPrintDocument.PrinterSettings.DefaultPageSettings.Landscape = False

'set the paper source
myPrintDocument.DefaultPageSettings.PaperSource = CType(Me.cboPaperTrayLetter.Text.Trim, PaperSource)

'print the envelope
Me.txtTemplate.Print(myPrintDocument)

... The problem is that the code:

CType(Me.cboPaperTrayLetter.Text.Trim, PaperSource)

... doesn't work - I get a message saying that "Value of type 'String' cannot be converted to System.Drawing.Printing.PaperSource"

Can anyone point me in the right direction for setting the PaperSource programatically?

Thanks in advance.
