Bonjour à tous,

Une petite question, très simple mais qui reste opaque à mes yeux de
novice.
J'ai crée une macro qui me permet de rapatrier tous les graph d'un
fichier sur une feuille nommée publication.

Maintenant j'aimerais utiliser et incorporer à cette macro le code
Dim Graph As ChartObject
For Each Graph In Sheets(12).ChartObjects
Graph.Chart.Export "C:adresse du dossier de destination" &
Graph.Name & ".png", "PNG"
Next Graph
issu d'excelabo.net
Quand je lance ma macro, aucune erreur apparente mais les images ne
sont pas crées alors que si je lance juste ce fragment de code, elle
apparaissent comme par magie sous le format chart1.png

Je pense ne pas utiliser la bonne syntaxe pour intégrer ce code au
reste, pour le moment ça a cette tête là :

Sub
[...]
Sheets("publication").Select
ActiveSheet.Paste
Dim Graph As ChartObject
For Each Graph In Sheets(12).ChartObjects
Graph.Chart.Export "C:adresse du dossier de destination" &
Graph.Name & ".png", "PNG"
Next Graph
Application.DisplayAlerts = False
Sheets("publication").Select
ActiveWindow.SelectedSheets.Delete
[...]
End Sub

La feuille "publication" est crée pour accueillir les graph puis
disparait une fois les images exportées. C'est bien la douxième
feuille crée d'où le sheets(12)

Merci d'avance pour votre précieuse aide

Bon j'ai déjà trouvé une erreur, car mes graph sur l'onglet publication
sont en fait des images et non plus des graphiques !!!
Normal qu'il ne trouve pas de graph dans cet onglet....
je ne sais pas quoi remplacer dans le code...

bonjour

une possibilité peut-être

Mettre dans le UF où existe un controle Image appelé Image1 sur une
action de commande d 'un bouton appelé CommandButton1 la procédure suivante.
Les procs au dessous de MODULE NAME sont à mettre dans un module
standard

Private Sub CommandButton1_Click()

ici, on va mettre dans le controle image1 une forme quelconque (pour l'essai
c 'était une photo) issue d'une feuille d'un classeur quelconque.
en l 'occurence, le format d'image adopté est xlpicture donc un métafichier
EMF. On aurait pu le mettre au format bitmap en écrivant xlbitmap

ActiveWorkbook.Sheets("Feuil3").shapes("cecile").Copy
Set Image1.Picture = PastePicture(xlPicture)

End Sub


***************************************************************************

* MODULE NAME: Paste Picture
* AUTHOR & DATE: STEPHEN BULLEN, Business Modelling Solutions Ltd.
* 15 November 1998
*
* CONTACT: Stephen@BMSLtd.co.uk
* WEB SITE: http://www.BMSLtd.co.uk
*
* DESCRIPTION: Creates a standard Picture object from whatever is on
the clipboard.
* This object can then be assigned to (for example) and
Image control
* on a userform. The PastePicture function takes an
optional argument of
* the picture type - xlBitmap or xlPicture.
*
* The code requires a reference to the "OLE Automation"
type library
*
* The code in this module has been derived from a
number of sources
* discovered on MSDN.
*
* To use it, just copy this module into your project,
then you can use:
* Set Image1.Picture = PastePicture(xlPicture)
* to paste a picture of whatever is on the clipboard
into a standard image control.
*
* PROCEDURES:
* PastePicture The entry point for the routine
* CreatePicture Private function to convert a bitmap or metafile
handle to an OLE reference
* fnOLEError Get the error text for an OLE error code

Je pense ne pas utiliser la bonne syntaxe pour intégrer ce code au

La feuille "publication" est crée pour accueillir les graph puis
disparait une fois les images exportées. C'est bien la douxième
feuille crée d'où le sheets(12)

Merci d'avance pour votre précieuse aide

Bon j'ai déjà trouvé une erreur, car mes graph sur l'onglet publication
sont en fait des images et non plus des graphiques !!!
Normal qu'il ne trouve pas de graph dans cet onglet....
je ne sais pas quoi remplacer dans le code...
