Bonjour Lemidi, bonjour le forum,
Essaie comme ça :
Sub Macro1()
Dim COL As Integer
COL = IIf(Cells(1, 1).Value = "", 1, Cells(1, Application.Columns.Count).End(xlToLeft).Column + 1)
Cells(1, COL).Value = UCase(TextBox2).Value
Range(2, COL).Value = ComboBox1.Value
Range(3, COL).Value = TextBox3.Value
Range(4, COL).Value = TextBox4.Value
Range(5, COL).Value = TextBox5.Value
TextBox1 = " "
TextBox2 = " "
ComboBox1 = " "
TextBox3 = " "
TextBox4 = " "
TextBox5 = " "
End Sub
