Bonjour à tous,

J'ai trouvé un moyen d'exporter le contenu d'un ou plusieurs datagridview vers excel. Mais je cherche désespérément à faire la même chose avec un label

Code : Sélectionner tout - Visualiser dans une fenêtre à part

'verfying the datagridview having data or not
        If ((DataGridView1.Columns.Count = 0) Or (DataGridView1.Rows.Count = 0)) Then
            MessageBox.Show("Aucunes données à exporter !", "Erreur !", MessageBoxButtons.OK, MessageBoxIcon.Information)

Dim excel As New Microsoft.Office.Interop.Excel.ApplicationClass

        wBook = excel.Workbooks.Add()
        wSheet = wBook.ActiveSheet()
 
        Dim dt As System.Data.DataTable = dset.Tables(0)
        Dim dc As System.Data.DataColumn
        Dim dr As System.Data.DataRow
        Dim colIndex As Integer = 0
        Dim rowIndex As Integer = 0
 
        For Each dc In dt.Columns
            colIndex = colIndex + 1
            excel.Cells(1, colIndex) = dc.ColumnName
        Next

            Next
        Next
        wSheet.Columns.AutoFit()
        Dim strFileName As String = "C:\ss.xls"
        Dim blnFileOpen As Boolean = False
        Try
            Dim fileTemp As System.IO.FileStream = System.IO.File.OpenWrite(strFileName)
            fileTemp.Close()
        Catch ex As Exception
            blnFileOpen = False
        End Try
 
        If System.IO.File.Exists(strFileName) Then
            System.IO.File.Delete(strFileName)
        End If
 
        wBook.SaveAs(strFileName)
        excel.Workbooks.Open(strFileName)
        excel.Visible = True
Voilà pour le datagrid mais je voudrait ajouter le contenu d'un label en plus mais là je coince...Merci
