### Attach to a Process

You can attach to an already running process (on Windows NT ) from the Startup dialog, or from the Process list item on the File menu of the Source or Session Control windows.

The Startup dialog appears when you start the debugger and do not specify a program to debug. You can also get to this dialog by choosing File->Startup from the Source or Session Control windows. Choose Process list from the Startup dialog, and select a process to debug.

Select a process from the process list. See under "Related Topics" for guidance on when to attach to a process, and for more details on using the Process List dialog.

When you attach to a process, the Run->Restart menu item is disabled.
