How to use OpenFileDialog to go to specific folder using Powershell? - powershell

Question

I have an GUI to select a file. I use OpenFileDialog. But when I press the button to open the file, the target folder sometime different. I want to make it default folder when I click the button.
Function Sel_File($InitialDirectory)
{
Add-Type -AssemblyName System.Windows.Forms
$OpenFileDialog = New-Object System.Windows.Forms.OpenFileDialog
$OpenFileDialog.Title = "Please Select File"
$OpenFileDialog.InitialDirectory = $InitialDirectory
$OpenFileDialog.filter = “All files (*.*)| *.*”
If ($OpenFileDialog.ShowDialog() -eq "Cancel")
{
[System.Windows.Forms.MessageBox]::Show("No File Selected. Please select a file !", "Error", 0,
[System.Windows.Forms.MessageBoxIcon]::Exclamation)
} $Global:SelectedFile = $OpenFileDialog.SafeFileName
}
Add-Type -AssemblyName System.Windows.Forms
[System.Windows.Forms.Application]::EnableVisualStyles()
$Form = New-Object system.Windows.Forms.Form
$Form.AutoSize = $true
$Form.text = "Auto GM Creation"
$Form.TopMost = $true
#----------------------
$ChooseML_L = New-Object system.Windows.Forms.Label
$ChooseML_L.text = "MLs"
$ChooseML_L.AutoSize = $true
$ChooseML_L.width = 25
$ChooseML_L.height = 10
$ChooseML_L.location = New-Object System.Drawing.Point(28,20)
$ChooseML_L.ForeColor = "#000000"
$SelectML = New-Object system.Windows.Forms.TextBox
$SelectML.AutoSize = $true
$SelectML.width = 150
$SelectML.height = 30
$SelectML.location = New-Object System.Drawing.Point(120,40)
$SelectML.Text = "Selected ML"
$ChooseML = New-Object System.Windows.Forms.Button
$ChooseML.text = "Select File"
$ChooseML.AutoSize = $true
$ChooseML.width = 90
$ChooseML.height = 20
$ChooseML.location = New-Object System.Drawing.Point(28,38)
$ChooseML.ForeColor = "#ffffff"
$ChooseML.BackColor = "#093c76"
$ChooseML.Add_Click({Sel_File
$SelectML.Text = $Global:SelectedFile
})
#----------
$Apply = New-Object system.Windows.Forms.Button
$Apply.BackColor = "#6996c8"
$Apply.text = "Apply"
$Apply.width = 99
$Apply.height = 30
$Apply.location = New-Object System.Drawing.Point(320,190)
#----------
$Cancel = New-Object system.Windows.Forms.Button
$Cancel.BackColor = "#6996c8"
$Cancel.text = "Cancel"
$Cancel.width = 98
$Cancel.height = 30
$Cancel.location = New-Object System.Drawing.Point(450,190)
$Cancel.Add_Click({$Form.Close()})
#-----------
$Prefix = New-Object system.Windows.Forms.Label
$Prefix.text = "Prefix"
$Prefix.AutoSize = $true
$Prefix.width = 25
$Prefix.height = 10
$Prefix.location = New-Object System.Drawing.Point(28,80)
$Prefix.ForeColor = "#000000"
$NB = New-Object system.Windows.Forms.RadioButton
$NB.text = "NB"
$NB.AutoSize = $true
$NB.BackColor = "#4a90e2"
$NB.width = 104
$NB.height = 20
$NB.location = New-Object System.Drawing.Point(28,100)
$DPC = New-Object system.Windows.Forms.RadioButton
$DPC.text = "DPC"
$DPC.AutoSize = $true
$DPC.BackColor = "#4a90e2"
$DPC.width = 104
$DPC.height = 20
$DPC.location = New-Object System.Drawing.Point(100,100)
$Form.Controls.AddRange(#($ChooseML, $Prefix, $ChooseML_L, $Apply, $Cancel, $SelectML, $NB, $DPC))
[void] $Form.ShowDialog()
With this code I can go to any folder.
My expectation I can go to a specific folder that I need and choose the file.
Updated
This is working
Function Sel_File
{
$OpenFileDialog = New-Object System.Windows.Forms.OpenFileDialog
$OpenFileDialog.InitialDirectory = “C:\Users\XX”
$OpenFileDialog.Title = "Please Select File"
$OpenFileDialog.filter = “All files (*.*)| *.*”
If ($OpenFileDialog.ShowDialog() -eq "Cancel")
{
[System.Windows.Forms.MessageBox]::Show("No File Selected. Please select a file !", "Error", 0,
[System.Windows.Forms.MessageBoxIcon]::Exclamation)
} $Global:SelectedFile = $OpenFileDialog.SafeFileName
}

If you want keep the last folder you can do it:
$OpenFileDialog.RestoreDirectory = $True
If you want just specify your initial directory modify your code like this:
Sel_File "c:\temp"
