(See the "Async" category on example-code.com for more information.) // // NOTE: This is very important: A TaskCompleted callback runs in the background thread. // (All callbacks from an async task, such as AbortCheck, PercentDone, ProgressInfo, etc. are in the background thread.) // An application that uses TaskCompleted must be very careful. // For example, user interface elements (such as labels, text boxes, etc.) may not be directly // accessible from a background thread, and could crash the application if directly accessed. Also, attempting to debug // code running in a background thread from an IDE, especially an older IDE (such as VB6) is likely to crash the IDE. SetDlgItemText(IDC_EDIT1,strOut.getUnicode()); } |
