How to write the code to a command button to paste text?

[Joacim Andersson]

...or if you want to insert the text use the SelText property instead of the Text property. If you want to add the text to the end of the textbox set the SelStart property to the length of the text in the textbox (see below) before setting the SelText property.

With txtDetails
    .SelStart = Len(.Text)
    .SelText = "Currency: Dollar" & vbCrLf & "Conversion ...." 
End With
