Error Creating window handle

[=?Utf-8?B?c2Vy?=]

Hi,

I am working on a windows application whose primary task is to apply all the
properties of one control to another. Hence i am using the SetValue method of
the PropertyDescrip tor. The application works fine but throws an exception
when the properties of combobox have to be set to the new control of the same
type.

The error stack is :
Error creating window handle.

On debugging i found it breaks when the property 'Parent' is to be set.
There is no other place that it breaks. I am unable to get to the unmanaged
code that might be executing at this time.
Please help me how would i trace to the unmanaged code if that could a
possible problem in this situation.

Thanks
