sta

I have a function which requires to be run in STA apartment state. I wan't to check if it is being run as STA, and if not spawn a new thread which runs in STA. How can I check which apartment state the current thread is being run in? Marek System.Threading.Thread.CurrentThread.GetApartmentState() Use this or a similar method inside the function: System.Threading.Thread.CurrentThread.GetApartmentState 来源： https://stackoverflow.com/questions/2378379/how-to-check-apartment-state-of-current-thread

If we make a thread STA like this: Thread.SetApartmentState(STA); then it cannot run code marked with [MTAThread] attribute. We have seen [STAThread] in windows and console applications but I have never seen code with [MTAThread] attribute and don't know which .NET libraries use this attribute. My question is what are the limitations of a thread with apartment state set to STA, in compare to threads with MTA apartment state (natural .NET threads) ? then it cannot run code marked with [MTAThread] attribute. That's not how it works. The apartment type is a property of a thread, not of a method.

I have a COM server (C++/STA (MFC based app)) and a COM client (C#/MTA). The COM server must live in an STA, since it's an MFC app (I have no choice in this matter). The client issues a call to the server, and the server issues a callback to the client. That's where the error happens ( RPC_E_CANTCALLOUT_ININPUTSYNCCALL ). I'm guessing if the server had been an MTA, this problem would never have arised, but sadly, the documentation for MFC explicitly denies initializing the apartment as an MTA. Any ideas on how to work around this problem? I have been toying with the idea of letting the server

Firstly I have read several answers to similar questions on the site but to be honest I find them a bit confusing (due to my lack of experience rather than the answers!). I am using a the FileSystemWatcher() class to monitor a folder for a file being created/changed. Once the event occurs I then want to load another form in the project. Instead of loading the form I get the error when the constructor on the new form is trying to execute. I am only using one thread - I'm not attempting to load the form under a different thread. My code is as follows //MainWindow public static void FolderWatcher

I'd like to convert Keith Hill's C# implementation of Get-Clipboard and Set-Clipboard into pure PowerShell as a .PSM1 file. Is there a way to spin up an STA thread in PowerShell as he does in his Cmdlet when working with the clipboard? The Blog Post The Code hoge TextBox doesn't require -STA switch. function Get-ClipBoard { Add-Type -AssemblyName System.Windows.Forms $tb = New-Object System.Windows.Forms.TextBox $tb.Multiline = $true $tb.Paste() $tb.Text } function Set-ClipBoard() { Param( [Parameter(ValueFromPipeline=$true)] [string] $text ) Add-Type -AssemblyName System.Windows.Forms $tb =

Although there are many questions about COM and STA/MTA (e.g. here ), most of them talk about applications which have a UI. I, however, have the following setup: A console application, which is by default Multi-Threaded Apartment (Main() explicitly has the [MTAThread] attribute). The main thread spawns some worker threads. The main thread instantiates a single-threaded COM object. The main thread calls Console.ReadLine() until the user hits 'q', after which the application terminates. A few questions: Numerous places mentions the need of a message pump for COM objects . Do I need to manually

What will be the expression for restricting a user to enter either 5 lines or 375 characters in a scrollable text field? I tried theese: ([A-Z])\w+ $0</a> var re,regs,val; if(OTHER.rawValue!=null) { val=OTHER.rawValue; //re=[a-zA-Z\d\s\-\,\#\.\+]+ //re=/abc(?!$){5}/ re=/\be(\w*)s\b/m{2,10}$; regs=val.match(re); if(!regs) { fieldname.rawValue=""; xfa.host.messageBox("ANY THING"); xfa.host.setFocus(fieldname) } } re=/abc(?!$){5}/ and many more... but I am not getting exact one to validate either 5 lines or 375 characters Try this: ^((.+\n){0,4}.+|.{1,375})$ $(document).ready(function() { $("
