Salut à tous,

J'ai pris il y a quelque temps une source sur ce site pour convertir du code RTF en HTML. Je l'ai quelque peu modifiée et je veux vous la faire partager (c'est une fonction liée au contrôle RTF...) :

Public Function ConvertToHTML(Box As Control, Optional FlgAlert As Boolean True, Optional b_netscape4 As Boolean False) As String 'System.Windows.Forms.RichTextBox
' Converti une chaine RTF en HTML
Dim strHTML As String
Dim strColour As String
Dim colorTmp As String
Dim txtTmp As String
Dim lienTmp As String
Dim blnBold As Boolean
Dim blnItalic As Boolean
Dim blnUnderline As Boolean
Dim strFont As String
Dim shtSize As Single 'Short
Dim strAlign As String
Dim numAligne As Integer
Dim lngOriginalStart As Long
Dim lngOriginalLength As Long
Dim intCount As Integer
