Inhalt aus Excel in Combo-Box

newbi2009 · 3. Juni 2024

Hallo Forum,

ich versuche den Inhalt einer Spalte eines Excel-Worksheets in einer Combo-Box auszugeben.

Grundsätzlich funktioniert das auch. Zumindest sind in, "$objCombobox.items" die gewünschtenNamen gespeichert.

Allerdings bekomme ich in der Combo-Box selber nur 4 x "system Object[]" angezeigt.

Wo liegt mein Fehler?

Hier mein Code:

[void] [System.Reflection.Assembly]::LoadWithPartialName("System.Windows.Forms")
[void] [System.Reflection.Assembly]::LoadWithPartialName("System.Drawing") 
$Namen = @()
$Zeile=1
$Page = "User"

$objForm = New-Object System.Windows.Forms.Form 
$objForm.Text = "Combobox"
$objForm.Size = New-Object System.Drawing.Size(300,200) 
$objForm.StartPosition = "CenterScreen"
$objForm.KeyPreview = $True

$OKButton = New-Object System.Windows.Forms.Button
$OKButton.Location = New-Object System.Drawing.Size(75,120)
$OKButton.Size = New-Object System.Drawing.Size(75,23)
$OKButton.Text = "OK"
$OKButton.Add_Click(
   {
 foreach ($objItem in $objCombobox.SelectedItem)
         {$global:x = $objItem
          $global:x}
         $objForm.Close()
       })
$objForm.Controls.Add($OKButton)

$CancelButton = New-Object System.Windows.Forms.Button
$CancelButton.Location = New-Object System.Drawing.Size(150,120)
$CancelButton.Size = New-Object System.Drawing.Size(75,23)
$CancelButton.Text = "Cancel"
$CancelButton.Add_Click({$objForm.Close()})
$objForm.Controls.Add($CancelButton)

$objLabel = New-Object System.Windows.Forms.Label
$objLabel.Location = New-Object System.Drawing.Size(10,20) 
$objLabel.Size = New-Object System.Drawing.Size(280,20) 
$objLabel.Text = "Treffen Sie bitte eine Auswahl:"
$objForm.Controls.Add($objLabel) 

$objCombobox = New-Object System.Windows.Forms.Combobox 
$objCombobox.Location = New-Object System.Drawing.Size(10,40) 
$objCombobox.Size = New-Object System.Drawing.Size(260,20) 
$objCombobox.Height = 70

$objexcel=New-Object -ComObject Excel.Application
$workbook=$objexcel.WorkBooks.Open('C:\temp\Users.xlsx')
$worksheet=$workbook.WorkSheets.item($Page)
$objexcel.Visible= $false


do {
      $Namen = @($worksheet.Cells.Item($Zeile,1).Text)
      write-host Name = $Namen
      [void] $objCombobox.Items.Add($Namen)
      $Zeile++
       }
while($worksheet.Cells.Item($Zeile,1).Text.Length -gt 0)

$objexcel.quit()
$objForm.Controls.Add($objCombobox) 

$objForm.Topmost = $True
$objForm.Add_Shown({$objForm.Activate()})
[void] $objForm.ShowDialog()
