PowerShell GUI with buttons, textbox and combobox



GUI makes life easier, but of course command line has a power of its own.

How to add a form in PowerShell with Buttons, TextBox and ComboBox?

Adding GUI forms in PowerShell must be done manually by code.

It’s not that hard, you just need to love PowerShell and see what it can do to automate IT administration and makes your life easier.

Anyway, code below introduces how to add GUI to PowerShell and it also illustrates how to make use of those GUI buttons and send a command to remote computers.

Code to add buttons, textbox and combobox in PowerShell, and how to execute a command after the button is clicked.

#initialize the main form
$form = new-object Windows.forms.form
$form.text = "Server Selection Form"

$form.minimumSize = New-Object System.Drawing.Size(600,300)
$form.maximumSize = New-Object System.Drawing.Size(600,300)

#add a button to the form
$button = new-object windows.forms.button
$button.text = "Close Me"

#action that the button will execute after it has been clicked
$button.add_click({$form.close()})


#add a textbox to the form
$theTbox = New-Object system.Windows.Forms.Textbox
$theTbox.location = New-Object system.Drawing.Size(0,50)
$theTbox.size = New-Object System.Drawing.Size(100,20)


#add a drop down combobox to the form
$the_combo = New-Object system.Windows.Forms.ComboBox
$the_combo.location = New-Object system.Drawing.Size(0,90)
$the_combo.size = New-Object System.Drawing.Size(200,20)

$the_combo.DropDownStyle = "Dropdownlist"

#add another button to the form
$Go_button = new-object windows.forms.button
$Go_button.text = "Do the Action"
$Go_button.location = New-Object system.Drawing.Size(0,190)
$Go_button.size = New-Object System.Drawing.Size(110,30)


#You can customized the command on this button
#Example below will shutdown the selected computer
#Invoke-command for remote computer can also be used (imagination is your friend 😊 )

$Go_button.add_click({Stop-Computer -ComputerName $theTbox.text})


#the “@” symbol will create an array out of the text file contents
$ComboList_Items = Get-Content -Path @("C:\dev\server_list.txt")

#Loop thru the text file or the array
#and add the contents to the combobox for selection
ForEach ($Server in $ComboList_Items) {

  $the_combo.Items.Add($Server)


}

$form.controls.add($theTbox)
$form.controls.add($button)
$form.controls.add($Go_button)

$form.controls.add($the_combo)
$form.Add_shown({$form.Activate()})


#action that will capture every time a value is selected on the combobox
$the_combo_SelectedIndexChanged=
{

 $theTbox.text= $the_combo.text

}

$the_combo.add_SelectedIndexChanged($the_combo_SelectedIndexChanged)

$form.ShowDialog()
#===== CODE ends here ======


#The contents of the text file just look like this:
Server-1
Server-2
Server-3
Server-4
Server-5
Server-6
Server-7
Localhost
Above contents is the one that is being read by this line below, change the path and the filename as necessary. It’s just for example purposes.
$ComboList_Items = Get-Content -Path @("C:\dev\server_list.txt")

WMIC get computer name

WMIC get computer model, manufacturer, computer name and  username. 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.

Notepad++ can process the contents of the file using regex. Example if the data has multiple rows or lines, and what is needed is to convert the whole lines of data into a single line. Notepad++ can easily do it using regex. However, if the data is on a single line and it needs to be converted into multiple lines or rows then regex can also be used for this case. Here’s an example on how to convert multiple rows or lines into a single line. Example data: Multiple rows, just a sample data. Press Ctrl+H, and  on "Find what" type: [\r\n]+ and on "Replace with" type with: , (white space) --white space is needed if need to have a space in between the data. See image below, "Regular Expression" must be se...

Print error 016-799 - Fuji Film Xerox

016-799 Fuji Xerox or Fuji Film print error code. That shows a description error as “Print instruction Fail detected in decomposer.” The error code and error description are alien languages for users and even system administrators who are not familiar with Fuji Xerox error code. The error code is quite simple and easy to fix, if the job print goes to the printer but print out doesn’t come out. So, basically the print job was received by the printer, but the printer just doesn’t know what type of paper or what size to use or which tray to utilize for the print out. In some instances, this is just a paper mismatch but the error description; if using Windows 10 to print does not exactly points to what is the issue. First thing to check, is the paper size selected by the user to print. Example, if the printer configuration is A3 and A4 sizes only. But then the person printing the file accidentally chooses “A4 Cover” then this error 016-799 will occur. ...
