PowerShell creating Windows Forms


From this Technet blog (link below), it shows how to add a Form and a Label control using PowerShell.


The PowerShell script below is a modification from above link.

Here, I will add a Button to the form, and also add an event click listener to the button.

And also add the simple but very useful "Msgbox".

Unlike VB.Net where you can just drag and drop your control on the form and VB.Net will do the necessary things on the background. For PowerShell you have to code the controls and location.

For the script below, location control for x and y coordinates is set.

If the location is not set, the control will be overlapping with each other and other controls cannot be seen.

To dig more about MSDN System Windows Forms, check out link below:



Here's the script below, with comments above the codes:

# =======================

Add-Type -AssemblyName System.Windows.Forms

# Add a Form to PowerShell
$Form = New-Object system.Windows.Forms.Form


#Set the FormBorderStyle cannot be drag manually
$Form.FormBorderStyle="Fixed3D"


#Set the text for the Form
$Form.Text = "Sample Form"


#Add a label control to the form
$Label = New-Object System.Windows.Forms.Label


#Add a text to the label control
$Label.Text = "This form is very simple."


#Set the Label control to Auto size to display whole string
$Label.AutoSize = $True


#Set the x and y coordinates location for the label control
#Top left corner x and y = 0
$Label.Location = "10,10"


#Add a new button to the form
$Button = New-Object System.Windows.Forms.Button

#Set the text or caption to the button
$Button.Text = "Simple Button"

#Set to Autosize so the text or caption will not be crop
$Button.AutoSize = $True


#Set Button Location below the label
$Button.Location = "10,40"


#Add a click event listener to the button
#Load the Net Framework to display and use Msgbox function


$Button.Add_Click({

[System.Reflection.Assembly]::LoadWithPartialName("Microsoft.VisualBasic")
[Microsoft.VisualBasic.Interaction]::MsgBox("Hello there!!! Testing Only!?",'YesNoCancel,Exclamation', "Respond please")

})



#Add the controls to the form and show the form
$Form.Controls.Add($Label)
$Form.Controls.Add($Button)
$Form.ShowDialog()

 # =======================

PowerShell script without the comments:

 # =======================
Add-Type -AssemblyName System.Windows.Forms
$Form = New-Object system.Windows.Forms.Form
$Form.FormBorderStyle="Fixed3D"
$Form.Text = "Sample Form"
$Label = New-Object System.Windows.Forms.Label
$Label.Text = "This form is very simple."
$Label.AutoSize = $True
$Label.Location = "10,10"

$Button = New-Object System.Windows.Forms.Button
$Button.Text = "Simple Button"
$Button.AutoSize = $True
$Button.Location = "10,40"

$Button.Add_Click({
[System.Reflection.Assembly]::LoadWithPartialName("Microsoft.VisualBasic")
[Microsoft.VisualBasic.Interaction]::MsgBox("Hello there!!! Testing Only!?",'YesNoCancel,Exclamation', "Respond please")
})


$Form.Controls.Add($Label)
$Form.Controls.Add($Button)
$Form.ShowDialog()
 # ======================= 

Output for above script:

Copy a single file using robocopy

Copy a single file using robocopy from a local folder to a shared folder on the network.
A simple rule of thumb before any disaster strike, don't interchange the source and the destination.

If source and destination is mistakenly reverse, files might get overwritten. To avoid any loss of data do a test with a dummy file to ensure things work perfectly.
Robocopy [source][destination]   [file to be copied]
robocopy c:\local_c_folder  \\PC_network\shared_folder   file_to_be_copied_xx.txt
The command will be completed successfully provided the network access right has no issues.

Robocopy works quite good on large files. A simple copy or xcopy command will also work but the speed might vary.

Robocopy is free it can be accessed from command line. No need to install the resource kit tool if the operating system is Windows 7 or newer version.

Copy files with selected file extension using PowerShell and Robocopy:

$extension = ('.pdf', '.jpg', '.txt')
gci d:\WorkFolde…

WMIC get computer name

WMIC is a command-line tool and that can generate information about computer model, its manufacturer, its username and other informations depending on the parameters provided.
Why would you need a command line tool if there’s a GUI to check?
If you have 20 or 100 computers, or even more. It’s quite a big task just checking the GUI to check the computer model and username.
If you have remote computers, you need to delegate someone in the remote office or location to check.
Or you can just write a batch file or script to automate the task.
Here’s the code below on how get computer model, manufacturer and the username.
Open an elevated command prompt and type:
wmic computersystem get "Model","Manufacturer", "Name", "UserName"
Just copy and paste the code above, the word “computersystem” does not need to be change to a computer name.
A sample output below will be generated if the co…
