Einar,
It works fine for me with the message box.
~~Bonnie
>I have found what the problem was. The problem was that I didn't post
exactly the same code as the code I was trying to run. The code I tried to run had an extra messagebox statement:
>
>System.Management.ManagementObjectCollection UserSearch = new System.Management.ManagementObjectSearcher("Select * FROM Win32_Account").Get();
>
>MessageBox.Show("Count:"+UserSearch.Count.ToString()); // removing this line will noth throw an exception in the foreach
>
>foreach(System.Management.ManagementObject mo in UserSearch)
>{
> if (MessageBox.Show(mo["Name"].ToString(),"next?",MessageBoxButtons.YesNo) == DialogResult.No)
> {
> break;
> }
>}
>>
>The exception that is thrown in the foreach has the following message:
>
>
>An unhandled exception of type 'System.Management.ManagementException' occurred in system.management.dll
>Additional information: COM object that has been separated from its underlying RCW can not be used.
>
>
>I am unsure why the messagebox causes problems.
>
>Could you guys please try to run the code above whith and without the messagebox before the foreach loop just to verify that I am not seeing things?
>
>Any explanation offered for this would also be appreciated.

>Thanks,
