Powershell: BeginInvoke Parameter Count Mismatch - forms

I am trying to create a powershell script that pulls up a simple GUI form, displays "Loading..." in the title bar while it takes about 10-20 seconds to load the data, then finally change the title to "Please choose from the following options..." after loading.
I've been following this guide pretty much down to the letter. So far everything works, except for the fact that I get a "Parameter Count Mismatch" error when I execute this line:
$objListbox.BeginInvoke(
[Action[string]] { param($Message) $objListbox.Items.Add = $Message },
$MyMessage
)
Basically what I'm trying to do is load up about two thousand names into a multiselect listbox, then allow users to select the names they want to import elsewhere. So far everything works, I just have to hit continue on the Powershell ISE editor, but I'd like to get rid of this error all together.

BeginInvoke is rather older than generics in the .NET framework, and considerably older than the delegate Action<T>. Specifically you cannot pass an instance of Action<T> to BeginInvoke.
Try casting to System.Delegate instead.

Powershell IE automation how to pass flags to navigate method?

How can I pass flags to the InternetExplorer navigate method
Specifically, no cache or read or write to history

What Ive tried so far, but just basing this off the BrowserNavConstants enum. Im not sure how one would pass more than one flag, nor if this is even taking effect, as my script seems to be pulling a page from previous execution.

get the current view which is displayed to user and verify

I am testing my eclipse rcp app GUI using a tool called RCPTT.
In rcptt, i want to check that a specific editor is opened or not.
right now i am using
get-view "Console" | get-table | is-disabled | verify-false
but this is wrong way to do verification.
using this code, if the console is not opened, than it click on console and do verification.
It passed all time.
So, is there any way to
- first get the current view(which view is displaying currently to user.)
- then verify this view.
Thanks
You can not solve it within ECL, there's no support for this.
However you can solve it with Java code. It's not easy, could be a few hours of work.
1) Write a Java method that detects the name of the active View and returns it as a String
2) Make sure it's part of your application as a static class's static method
3) Invoke it from your ECL script with the invoke-static command
4) Compare the returned value in ECL script to what you've expected
Check methods parseComposites(), viewOrEditorIsFocused() and checkNextComposite() from this tutorial:
https://openchrom.wordpress.com/2011/08/12/capture-a-snapshot-of-the-active-vieweditor-in-a-rcp-application/
You do not need all the code from it and you need some editing too.
If you make an error/typo at points 2) or 3), then RCPTT-runner will simply throw an Exception without further explanation; be careful there.

powershell and switch parameter type

I can't get this working and from documentation and examples on the web i cannot work out why.
My code is simple, its just a script to which i want to pass a parameter, not every time. so i've laid the param section as thus
param(
[Parameter(Mandatory=$true)]
[string]$startOfName,
[ValidateRange(0,6)]
[int]$numberOfServers = 1,
[switch]$consecutiveNumbers
)
and im calling the scipt as follows.
.\Get-NextServerName.ps1 -startOfName servername -numberOfServers 5 -consecutiveNumbers
which gives me the lovely error message:
Get-NextServerName.ps1 : A parameter cannot be found that matches parameter name 'consecutiveNumbers'.
Can anyone see anything that I'm doing wrong?
This looks like being a bug in Powergui.Tried it from a command prompt and it worked first time. still won't work in Powergui. Think it might be related to the way it passes command line arguments from the shell pane to the script. Probably going to open a call to discuss, unless I find out im on a way old version.

Working with layout object attributes and variables in FileMaker

This is the first time I'm encountering GetLayoutObjectAttribute and I am having serious issues with it. My variable $web won't set. I think it's because PD_WebV isn't the right object name to refer to, but I don't know how to find the right object name. I can't find the objects name when I hit Edit Layout, so does anyone know how to find an layout objects name?
Loop
Pause/Resume Script [Duration (seconds): 1]
Set Variable[$Web; Value: GetLayoutObjectAttribute("PD_WebV";"content")]
If[$Web="done"]
#execute if statements
After Edit:
After some troubleshooting, I found out that PD_WebV is the right object name to refer and it's refered to correctly, so my new question is why doesn't the script go to the line If[$Web="done"] and how could I fix it? Ss my If statement not evaluating something it should be? Is my $web variable never set to done or is the issue something completely different? Would the problem possibly have to do with my WebDirect sharing settings? Any guidance would help. Thanks.
After, After Edit:
So now that my application is getting past Set Variable[$Web; Value: GetLayoutObjectAttribute("PD_WebV";"content")], the variable $web only equals <HTML></HTML>. Does anyone know a way, without using javascript, to test the inside of the html tags?
Also, I printed the bounds of the webViewer PD_WebV that I can't locate on the layout but am referring to in the script. The bounds that are printed are different each time I run the script. Is the usual or unusual? My source is also about:blank so it doesn't look like I'm sourcing from a URL
Is my $web variable never set to done or is the issue something
completely different?
If you're doing:
Set Variable[$Web; Value: GetLayoutObjectAttribute("PD_WebV";"content")]
then the only time
$Web="done"
will return true is when the web page loaded into your web viewer contains exactly the string "done" (in practical terms, that's never).
I have already suggested in a comment that you test for:
PatternCount ( $webpage ; "</html>" )
This is assuming you want the subsequent steps to execute only after the page has finished loading. The entire script would look something like this:
Loop
Pause/Resume Script [Duration (seconds): 1]
Set Variable[$Web; Value: GetLayoutObjectAttribute("PD_WebV";"content")]
Exit Loop If [ PatternCount ( $webpage ; "</html>" ) ]
End Loop
# execute statements
You might also want to add a counter to the loop and exit the script after n trials.
Ah, I reread your question.
To set the object name for your webviewer so that the GetLayoutObjectAttribute function works you need to set it in the Name field in the inspector when you have the webviewer selected.
e.g.:
After that your variable should populate.
Be aware
What it will populate with will be all of the html from the browser, i.e. not a boolean true/false liek your conditional suggests.
I'm not sure exactly what you're trying to accomplish, but to be able to determine a result from your web viewer you'll need to either parse the HTML to see if it's content contains what you're looking for or within the code you're setting the webviewer with, fire a javascript function that calls back to the FileMaker file using a FileMaker url.

Error when re-declaring item as record via PowerShell - "The file has been modified "SHAREPOINT\system"

We have had a PowerShell script scheduled and executing successfully for the past 3-4 months (In both Test and Prod). The purpose of the script is to update document properties in SharePoint when certain triggers are fired from external systems. Without getting into too much detail, below is the code that has been used to update item properties for a document that has been declared a record:
$recordsmanagement=[Microsoft.Office.RecordsManagement.RecordsRepository.Records]
$recordsmanagement::UndeclareItemAsRecord($item)
$item = $list.GetItemById($item.id)
$item.File.CheckOut()
$item[$sSpFieldName]=$sDbValue
$item.Update()
$item = $list.GetItemById($item.id)
$item.File.CheckIn("")
$recordsmanagement::DeclareItemAsRecord($item)
This code has worked hundreds of times without a problem. For some reason, this code started bombing a week ago on the last line (when re-declaring as a record):
System.Management.Automation.MethodInvocationException: Exception calling "DeclareItemAsRecord" with "1" argument(s): "The file /lib/folder/file.pdf has been modified by SHAREPOINT\system on 10 Oct 2012 00:00:47 -0500."
The other weird part is that this is only happening in Prod. The Test environment seems to execute just fine. I haven't tried a fix for production yet, but I'm pretty sure I can just get the $item object again using GetItemById (after the CheckIn). I'm a little hesitant to do this just yet as I wanted to get some other people's perspective first.
Does anyone have any input on this? Thanks in advance.
I think the best bet is to get the item again after the checkin as you say.
The error message indicates exactly that. You are trying to perform an operation on a SPListItem that has been modified. So pull it again using GetItemById before you declare it as a record.
Why it only happens on some records and on some environment I am not sure. I guess Sharepoint is a bit temperamental.
Thing I would try as well:
Check if there is any workflow doing some work on that item when you check it in
Try to use SystemUpdate() instead of Update() if that suits your requirements
Good luck
