MapForums

Hi,
I'm having trouble with the ObjectsFromPoint method. The following code throws an exception whenever there is a TextBox "under" the x, y.

MapPoint.FindResult fr = axMappointCtrl.ActiveMap.ObjectsFromPoint(x,y)
foreach(object o in fr)
{
Debug.Writeline("Doing nothing...");
}

The method is fine as long as there is no textBox returned to the fr collection.

When it is, the following exeption stack can be traced:

at System.Runtime.InteropServices.Marshal.ThrowExcept ionForHR(Int32 errorCode, IntPtr errorInfo)
at System.Runtime.InteropServices.Marshal.ThrowExcept ionForHR(Int32 errorCode)
at System.Runtime.InteropServices.CustomMarshalers.En umeratorViewOfEnumVariant.GetNextElems()
at System.Runtime.InteropServices.CustomMarshalers.En umeratorViewOfEnumVariant.MoveNext()


Please, can anyone help me with this?

Hi,

What is the offending line of code ?

Hi,

I read this on a Microsoft page, guess this is what happens in my code.


To answer your question: The exception is thrown in the foreach loop and since I don't do anythin in it it is the iteration itself that fails.

Hi,

Thanks for feedback. This is probably the reason.
