Affichage des images dans un form

Bonjour,

Je travaille sur le traitement des images en .Net.
J'ai un problème d'affichage des images.
En effet, lorsque je clique le menu File -> Open l'image ne s'affiche pas
dans le form.

Le code source de mon projet est téléchargeable à partir de ce lien:
http://www.4shared.com/file/zRcK2dT4/Hope.html


Est-ce que vous pouvez m'aider?
Merci d'avance.

mets nous le bout de code ici, rare sont ceux qui veulent télécharger des sources

Voici le code:
...

Code:

---

1 2 3 4 5

// On "File->Open" item clicked private void OpenItem_Click(object sender, EventArgs e) { OpenFile(); }

Code:

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29

// Open file public void OpenFile() { if (ofd.ShowDialog() == DialogResult.OK) { ImageDoc imgDoc = null;   try { // create image document imgDoc = new ImageDoc(ofd.FileName, (IDocumentsHost)this); imgDoc.Text = Path.GetFileName(ofd.FileName);   } catch (ApplicationException ex) { MessageBox.Show(ex.Message, "Error", MessageBoxButtons.OK, MessageBoxIcon.Error); }   if (imgDoc != null) { imgDoc.Show(dockManager); imgDoc.Focus();   // set events SetupDocumentEvents(imgDoc); } } }

je ne connais pas la classe imagedoc ...

tu as fait du pas à pas pour être sûr que le code est bien exécuté comme tu le penses ?

voici la classe imageDoc:
