using variables

[mqh77777]

I have a simple form that has a text field and 1 button. On the text field the user will enter a computer name. When they press the button I want to to use the computer named entered in the text field.

My text field is called GetPC, how do I use that GetPC variable in my powershell script?

Thank you for posting, mqh777.

Did you remember to include the following?

• 1. Product, version and build (e.g. Product: PowerShell Studio 2014, Version & Build: 4.1.71. Version and build information can be found in the product's About box accessed by clicking the blue icon with the 'i' in the upper right hand corner of the ribbon.)
  2. Specify if you are running a 32 or 64 bit version
  3. Specify your operating system and if it is 32 or 64 bit.
  4. Attach a screenshot if your issue can be seen on the screen
  5. Attach a zip file if you have multiple files (crash reports, log entries, etc.) related to your issue.

If not, please take a moment to edit your original post or reply to this one.

Prepending a $ to the beginning of the object name will access the variable associated with that object. So if your textbox is called GetPC, then use $GetPC to use that variable.

Press the period after you type out the variable will show all of the methods and properties associated with that object. So

Code: Select all

$aVariable = $GetPC.text

will allow you to read the value of the text property of the text box into the variable $aVariable.

thank you. I ran my script with the $ and it then tries to run a get-WMIObject against $GetPC. It returns an error "the RPC server is unavaliable"

yet, when I run the same get-wmiobject command against the same computer in PowerShell ISE it works.

Why would PowerGUI have this RPC error?

[Ferdinand Rios]

When you wrote "PowerGUI" did you mean PowerShell Studio?

Are you running get-WMIObject against $GetPC or against $GetPC.text? $GetPC is the TextBox object. if you need to pass the computer name to the Get-WMIObject you need to use $GetPC.text as I stated in the previous posting.

ok, that worked, thank you. I can now run this and it will create a .TXT file with all of the mapped drives for a machine.

But how do you do the following: I enter a computer name and press 1 button. This button will execute this command.

Get-WMIObject win32_mappedlogicaldisk -ComputerName $GetPC.text | Select Name, ProviderName | fl

How do I display the mapped drives on a new Form?

[mqh77777]

I found a Sapien doc on how to call other forms and I'm using the provided template.
Once I get my mapped drives how do I display them on the Child-Form?

That really depends on how you wish to present it and what you want to do with the information.

I recommend looking at the samples provided with PowerShell Studio:

Ribbon->Help->Product Support->Samples
