有没有一种方法以编程设定的ApartmentState到STA？ [英] Is there a way to programatically set the ApartmentState to STA?

问题描述

所以，我的工作在PowerShell中的GUI当某些组合框被点击，我被扔的错误。被抛出的错误后，我可能会下降在下拉列表下来，看它的内容，但如果我转移到另一个COMBOX在同一DataGridView的，我会得到相同的初始错误之前，我可以看到下拉列表。

我在TechNet PowerShell的论坛登载，并获得我需要在单线程单元（STA）运行我的图形用户界面的答案。 PowerShell中，默认情况下，运行在MTA，但你可以调用 powershell.exe <当覆盖这个（V2.0）使用 -Sta 开关/ code>。

不过，我的GUI简单地调用默认的PowerShell的应用程序（在MTA模式）的的所以我的问题是，有没有办法以编程方式从我的GUI /脚本里面设置的ApartmentState？的

如果没有，我的下一个尝试是将检测单元状态，并尝试重新踢了我的图形用户界面，从我的GUI的inital负载是这样的：

  powershell.exe -Sta myguiprog.ps1
 

任何帮助是AP preciated ...

编辑：

所以，我的变通办法工作：

 如果（[threading.thread] :: CurrentThread.GetApartmentState（）当量MTA）{
    ＆放大器; $ ENV：SYSTEMROOT \ SYSTEM32 \ WindowsPowerShell \ V1.0 \ powershell.exe -Sta $ MyInvocation.ScriptName
}
 

解决方案

如果您有 pscx 安装，你可以使用调用-公寓-Apartment STA -Ex pression {...} 。

如果没有，看看<一href="http://blogs.msdn.com/b/powershell/archive/2008/05/22/wpf-powershell-part-1-hello-world-welcome-to-the-week-of-wpf.aspx">WPF ＆放大器; PowerShell的 - 第1部分（的Hello World＆功放;欢迎WPF的周），其中詹姆斯与STA创建运行空间。另有消息可能会在PowerShell中 异步性。

或者有关自定义cmdlet的一些旧的帖子<一href="http://get-powershell.com/post/2008/11/07/Single-Threaded-Apartment-in-PowerShell-V1.aspx">Single螺纹公寓在PowerShell中V1 。

So I'm working on a GUI in PowerShell where I was throwing errors when certain comboboxes were clicked. after the error was thrown, I could drop the combobox list down and see it's contents, but if I shifted to another combox on the same datagridview, I would get the same initial error before I could see the drop-down list.

I posted this in the TechNet PowerShell forums and got the answer that I needed to run my GUI in single threaded apartment (STA). PowerShell, by default, runs in MTA but you can overwrite this (in v2.0) by using the -STA switch when calling powershell.exe.

However, my GUI simply invokes the default PowerShell application (in MTA mode) so my question is, is there a way to programatically set the apartmentstate from inside of my GUI/script?

If not, my next attempt would be to detect the apartment state and try to re-kick off my GUI from the inital load of my gui with something like:

powershell.exe -STA myguiprog.ps1

Any help is appreciated...

Edit:

So my workaround DOES work:

if ([threading.thread]::CurrentThread.GetApartmentState() -eq "MTA") {
    & $env:SystemRoot\system32\WindowsPowerShell\v1.0\powershell.exe -sta $MyInvocation.ScriptName
}

解决方案

If you have pscx installed, you can use Invoke-Apartment -Apartment STA -Expression { .... }.

If not, have a look at WPF & PowerShell – Part 1 ( Hello World & Welcome to the Week of WPF ) where James creates runspace with STA. Another source might be Asynchronicity in PowerShell.

Or some older posts about custom cmdlet Single Threaded Apartment in PowerShell V1.
