COde片段如下所示。 HI Friends, I am facing a problem while joining a STA thread to MTA thread. Actually the requirement was some thing like describe below.1. I have a exe which is using some dialog boxes. 2. These dialog boxes are using MSFlexGrid. This component is a Com component. 3.so in order to run it with Vb.Net exe i had to run this dialog box in a STA thread. 4. to achive this i created a new thread and set the Apartment status STA.5.it was working fine when i run the code. but if click on exe than at the time of join it throws an unhandled exception.if i click on continue button of exception dialog box it runs successfully. how ever i can not ignore this exception.6. exception contains below text (i know its a bog message but i am stuck here for last couple of days.). ************** Exception Text **************System.AccessViolationException: Attempted to read or write protected memory.

Also, why are you using msflexgrid? Are you aware of DataGridView? 实际上它是一个非常大的Vb6.0到VB.Net的迁移项目。它包含大约16个组件。我无法将整个项目作为STA。 我知道DataGridView，但现在它无法更改组件，因为它在许多其他应用程序中使用。我遇到了msflexgrid的问题。所以我创建了一个线程并将公寓设置为STA。最初它工作正常（或可能是我忽略了错误）。但现在它给了我上面提到的错误。我只是想知道是否有任何指南加入STA与MTA。我也试过了事件机制，但似乎这个线程死了就会出现这个错误。Actually its a very large Vb6.0 to VB.Net migrated project. it contains some 16 components. i can not make whole project as STA.i know about DataGridView but right now its not possible to change the component, as its being used in many other applications. I had a problem with msflexgrid. so i created a thread and set the apartment as STA. initially it was working fine(or may be i ignored the error). but now it gives me the above mentioned error. i just wanted to know if there is any guideline to join a STA with MTA. i have tried event mechanism also, but it seems like when this thread dies it gives this error. 为什么在Start（）之后调用Join（）？ 编辑：没关系，我猜想。 如果你制作了自己的Join（）版本怎么办？ 像循环这样的东西当那个线程仍处于活动状态时。 在你的循环中你会打电话给 Application.DoEvents 和 Thread.Sleep（100） 如果你不想让它永远等待，也许可以检查一个DateTime对象Why do you call a Join() right after the Start()? Nevermind that I suppose. What if you made your own version of Join()?Something like looping while that thread is still active.And in your loop you would call Application.DoEvents and Thread.Sleep(100) And maybe checking a DateTime object if you don''t want it to wait forever 这篇关于将STA线程加入MTA线程的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持！
