Hello guys

I'm getting following error "The current thread must set to Single
Thread Apartment (STA) mode before OLE calls can be made. Ensure that
your Main function has STAThreadAttribute marked on it" on CTRL+C on
grid cell; I'm opening this form from a .net dll; so there's no Main()
method;

How can I fix this?

Thanks

Hi Vishy,

You should explicitly change the threading model to single-thread apartment
(STA) before creating your form. There are two ways to do this 1) decorate
your Main method with the STAThreadAttribute attribute 2) use the following
code System.Threading.Thread.CurrentThread.ApartmentState =
System.Threading.ApartmentState.STA;

See here for additional information

Thanks Paul for reply

But I don't have a Main() method in my form; or application; where can
I add this code?
I tried adding it to form_load() but it didn't work

Hello,
I'm opening this form from a .net dll; so there's no Main() method;
Click to expand...

I think the calling application has to specify STA then.
If it doesn't use a GUI, you might also consider creating a new thread in
the library.

Thanks Michael

I fixed the problem; patch was strange; i derived DataGrid into
another class; handled ProcessDialogKey event and it worked; no more
STAThread exception
I don't know the implications of this fix;but it worked
