I have exe file downloaded in the VM in specific folder, I am trying to install Adobe using Powershell dsc code.
Script is failing with below error during execution (Configuration is called through ARM template), however if I check inside the VM, adobe is installed.
Tried running the same script manually inside the VM. Not facing any error though.
[{"code":"VMExtensionProvisioningError","message":"VM has reported a failure when processing extension 'configureWindowsServer'. Error message: "DSC Configuration 'Adobe' completed with error(s).

From a Power Shell window, I can use the clear or cls as you all know.
But messing around I found that clear(5) or cls(5) works, also clear the screen (any number works, including negative numbers). But if I try something like clear(abc) or clear("abc") it throws error
abc: The term 'abc' is not recognized as a name of a cmdlet, function, script file, or executable program.
Check the spelling of the name, or if a path was included, verify that the path is correct and try again.
Why it accepts a number, if the number doesn't do anything (is not the number of lines to clear or anything), and why throws error with non-numerical?
Building on Santiago Squarzon's comment: the Clear-Host command is a function. You can see this by running:
Get-Command Clear-Host -OutVariable cmd
Output
CommandType Name
----------- ----
Function Clear-Host
Since functions are written in PowerShell, you can also view the contents (definition):
$cmd.Definition
Output (Windows PowerShell 5.1)
$RawUI = $Host.UI.RawUI
$RawUI.CursorPosition = #{X=0;Y=0}
$RawUI.SetBufferContents(
#{Top = -1; Bottom = -1; Right = -1; Left = -1},
#{Character = ' '; ForegroundColor = $rawui.ForegroundColor; BackgroundColor = $rawui.BackgroundColor})

You can view about_Functions_Advanced to read more about this, but without [CmdletBinding()], it's not an "advanced" function and so it won't be validating its arguments in the same way.
Instead the function can access its unnamed arguments in $args but as you can see in the definition, it does not.
Get-Help Clear-Host will show you that it is not expecting any parameters:

I'm testing the Greeting contract in "workshop--exploring-assemblyscript-contracts" and try to pass parameter to saveMyMessage function but always get error. There maybe problem with quotations marks, I tried with " or '` but nothing succeeds. I'm running it on Windows.
This is the suggestion from the code:
near call greeting..testnet saveMyMessage '{"message": "bob? you in there?"}' --account-id .testnet
When I try
near call %ID% saveMyMessage '{"message": "bob? you in there?"}' --account-id %ID%
Or replace " with " or end single quote with ` always get error like this
Unknown argument: bob? you in there?}'
For starters, it appears you have a syntax error with 2 dots instead of 1 here - greeting..testnet
Have you tried seeing what %ID% is?
I would try the following syntax, but make sure when you set your IDenv variable, that it returns the correct value when you run echo $ID
Once you have your env variables set up correctly, try the following:
near call $ID saveMyMessage '{"message": "bob? you in there?"}' --account-id $ID
I have three date type variables passed from a batch file as strings. When they come over to the PS script, they are seen as:
20190710 112538
20190710 112538
20190710
The problem I am facing is that when I attempt to parse them, I receive an error stating that the string is not recognized as a valid DateTime.
I have tried changing the culture to and invariant one and no difference. I am sure I am missing something. Could I get some help with parsing these strings successfully?

how to use choice parameter in Jenkins declarative pipeline in batch command.
I'm using following stage:
choice(
choices: 'apply\ndestroy\n',
description: '',
name: 'DESTROY_OR_APPLY')
stage ('temp') {
steps {
echo "type ${params.DESTROY_OR_APPLY}"
bat'echo "type01 ${params.DESTROY_OR_APPLY}"'
bat'echo "type01 %{params.DESTROY_OR_APPLY}%"'
bat'echo type01 [${params.DESTROY_OR_APPLY}]'
}
echo does resolve to correct parameter value but under bat none of the above code works.
You almost got the syntax right.
If you change it to one of the below options, the bat command receives the value of your choice.
steps {
bat "echo type01 ${DESTROY_OR_APPLY}"
}
or
steps {
bat 'echo type01 ' + DESTROY_OR_APPLY
}
You can also use ${params.DESTROY_OR_APPLY} in the first or params.DESTROY_OR_APPLY in the second example if you want to use the params definition consequently in your code.
