    Dim LineWidth As Single = Convert.ToSingle(cboSize.Text)
    Dim LineHeight As Single = Convert.ToSingle(cboLength.Text)
    ' Generate a new Bitmap
    Dim penBlack As New Drawing.Pen(Color.Black, LineWidth)  ' Pen for black lines
 
    G.FillRectangle(Brushes.White, Pos.X, Pos.Y, LineWidth * Input.Length, LineHeight)
    Dim rx As Single = Pos.X
 
    For iPos As Integer = 0 To Input.Length - 1
        If Input(iPos) = "1"c Then ' Only draw black lines
            G.DrawLine(penBlack, rx, Pos.Y, rx,Pos.Y + LineHeight)
        End If
        rx += LineWidth
    Next
End Sub

le problème vient du code picBarcode.
voici un exemple pour aperçu du logiciel code barre :

Code :

Private Sub PrintImage(ByVal sender As Object, ByVal e As System.Drawing.Printing.PrintPageEventArgs) Handles printDoc.PrintPage

    e.Graphics.DrawImage(Bitmap2, 0, 0)
    myBitmap2.Dispose()

Bitmap1 ou myBitmap1 ?
Parce que je vois le dispose qui semble être effectué sur quelque chose de non déclaré auparavant... A mon avis çà devrait être Bitmap1

Merci MK4-hurrican
J'ai testé avec bitmap1 j'ai plus le défaut mais j'ai toujours le problème quand j'imprime j'ai une feuille vierge je comprend pas bien la.

Si ça peut guidé j'ai une erreur je ne pense pas que ça gène a : GenerateBarcode(BINARY) (argument non spécifié pour le paramètre 'G' de private sub generatebarcode(imput as string, G as graphics,pos As PointF)

Quelqu'un peux m'aider SVP ?
Page vierge lors de l'impression du code barre

**ProgElecT** · 28/01/2022, 22h57

Salut

Es tu sûr de la ligne 555 du code

Code :

Sélectionner tout - Visualiser dans une fenêtre à part

            If Input(iPos) = "1"c Then ' Only draw black lines

Le c la syntaxe me semble des plus suspect, comme la fonction GenerateBarcode est appelée dans Private Sub, PrintPage, essayes de retirer le c
Perso je verrai mieux

Code :

Sélectionner tout - Visualiser dans une fenêtre à part

            If Input(iPos) = "1" Then ' Only draw black lines

Bonjour
Toujours le meme probléme impression d'une feuille vierge

Salut

Essais de mettre des MessageBox.Show() à des endroit stratégique pour vérifier ta variable Input?

        MessageBox.Show("Input = " & Input)
        MessageBox.Show("Entrée dans la boucle For ... Next")
        For iPos As Integer = 0 To Input.Length - 1
            MessageBox.Show("Input(iPos) = " & Input(iPos))
            If Input(iPos) = "1"c Then ' Only draw black lines
                G.DrawLine(penBlack, rx, Pos.Y, rx, Pos.Y + LineHeight)
            End If
            rx += LineWidth
        Next
        MessageBox.Show("Sortie de la boucle For ... Next")

Personnellement je n'ai pas vu de gestion du BeginPage ni du EndPage dans le code...
Maintenant on ne peut pas reprendre tout le programme pour le réécrire.
