Please could somebody recommend a Powershell, mouse tutorial. I have been searching the internet but cannot find instructions on how to do then following.
I have data in a database which I want to select via a mouse. I have been able to display an output from the database in a Textbox, but cannot select it.
What I want to be able to do is select the line in the output and then use the information in that line.
Any ideas greatly appreciated.

Answer 1

You can use Out-GridView -PassThru on Windows to achieve this:
$selected = $datatable |Out-GridView -PassThru
Select the relevant line(s) by clicking (ctrl-click for more than one), and click Ok in the lower right corner.
$selected will then contain the relevant row(s)

Answer 2

Here are some functions I use myself. I've tried to adapt them to how you will use it.
Add-Type -AssemblyName System.Windows.Forms
$wshell = New-Object -ComObject wscript.shell;
function Mouse-signature-import(){
$global:signature=#'
[DllImport("user32.dll",CharSet=CharSet.Auto, CallingConvention=CallingConvention.StdCall)]
public static extern void mouse_event(long dwFlags, long dx, long dy, long cButtons, long dwExtraInfo);
'#
$global:SendMouseClick = Add-Type -memberDefinition $global:signature -name "Win32MouseEventNew" -namespace Win32Functions -passThru
}
function Mouse-Drag($from1,$from2,$to1,$to2){
Mouse-signature-import
[System.Windows.Forms.Cursor]::Position = "$from1,$from2"
$global:SendMouseClick::mouse_event(0x00000002, 0, 0, 0, 0);
[System.Windows.Forms.Cursor]::Position = "$to1,$to2"
start-sleep -m 1500 # If we do not sleep, then the drag does not work right.
$global:SendMouseClick::mouse_event(0x00000004, 0, 0, 0, 0);
write-host -f yellow -b black "Mouse-Drag" -nonewline; write-host -f Gray " from " -NoNewline; write-host -f Magenta "[" -nonewline; write-host -f Red "$from1 $from2" -nonewline;write-host -f Magenta "]" -nonewline; write-host -f Gray " to " -NoNewline; write-host -f Magenta "[" -nonewline; write-host -f Red "$to1 $to2" -nonewline; write-host -f Magenta "]";
}
function SendInput($a){
[System.Windows.Forms.SendKeys]::SendWait($a)
}
start-sleep -s 1
Mouse-Drag 90 166 126 358
start-sleep -s 1
sendInput "^(c)"
$a = Get-Clipboard
$a
And to figure out the coordinates for where I want to move the mouse cursor to, I use this: https://learn-powershell.net/2015/11/30/create-a-mouse-cursor-tracker-using-powershell-and-wpf/
Basically what I'm doing above is moving the mouse to a cursor position, then I drag the mouse to position 2. Send a CTRL+C to copy what we have highlighted, then use get-clipboard to push the selected text into a variable ($a).
This method is not perfect for what you're trying to do, but it is how you want to do it so this is why I supplied my code. I would recommend trying to get the data through some other means as there is a lot that could go wrong here.

Answer 3

What I am doing is returning a table from a function (RetriveData) that retrieves it from a database.
$listTable = RetriveData | Format-Table | Out-String
Write-host “$listTable”
$selected = $listTable | Out-GridView –PassThru
Write-host “$selected”
The write hosts are showing the table contents as I was expecting. The dialogue opened by Out-GridView shows the table highlighted in light blue, but seems to only be selectable as a complete table.
Am I using the | Format-Table | Out-String correctly here?
The code being used in the RetriveData function to return from the data base is.
$table = Invoke-Sqlcmd –ServerInstance $databaseServer $databaseName –Query $sql
Return $table
