Impression code barre

Bonjour,
J'ai une interface qui me génère un code 128 mais au moment de l'impression la feuille sort bien mais vierge.
D’où peut venir le problème ?

Je dois rentrer la commande, repère, ouvrant et tape une lettre dans la grande barre ( car j'arrive pas a le faire automatiquement des que l'on renseigne les 3 éléments ) et après régénérer le code barre apparait et au moment de l'impression plus rien.


Voici le code

Code:

Bonjour, j'ai regarder ce lien dans le site code projet : https://www.codeproject.com/Tips/122...erator-Creator

if faut regarder dans Comments and Discussions en bas de la page et aller dans les discutions et du clique sur Printing the barcode.

voici le code :

Code:

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17

Private Sub GenerateBarcode(ByVal Input As String, ByVal G As Graphics, ByVal Pos As PointF)   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

PDoc.PrinterSettings.DefaultPageSettings.Landscape = False PDoc.Print()   End Sub

Private Sub PrintPage(ByVal sender As Object, ByVal e As System.Drawing.Printing.PrintPageEventArgs)   'Print the barcode at the specified position GenerateBarcode(BINARY, e.Graphics, New PointF(50, 50))   'If the document has more pages 'e.HasMorePages=True e.HasMorePages = False   End Sub

cordialement,

Merci pour la réponse Je me suis inspirer de cet exemple mais malheureuse cela ne fonctionne pas.
Merci

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

Code:

---

1 2 3 4 5 6

Private Sub PrintImage(ByVal sender As Object, ByVal e As System.Drawing.Printing.PrintPageEventArgs) Handles printDoc.PrintPage Dim Bitmap2 As Bitmap = New Bitmap(Me.Width, Me.Height) Me.DrawToBitmap(Bitmap2, New Rectangle(0, 0, Me.Width, Me.Height)) e.Graphics.DrawImage(Bitmap2, 0, 0) myBitmap2.Dispose() End Sub

---

le code pour imprimer picBarcode du code barre fonctionne très bien :

Code:

Bonjour,
J'ai modifié le printimage j'ai un défaut bitmap1 n'est pas déclarer, je m'en sort pas

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

Salut

Es tu sûr de la ligne 555 du code

Code:

---

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:

---

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?

Code:

---

1 2 3 4 5 6 7 8 9 10

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.
