- Hello all,
-
- I have been having some weird PM problems that I was hoping someone could
- shed some light on. Basically the problem is that if I start a thread
- from a dialog, and then from within the thread try to send messages to
- the dialog items, or set DlgItemText, the calls fail. I have not omitted
- the all important step of getting a PM anchor block handle for each thread.
-
- The two specific cases I have noticed are, WinSendMsg fails, while
- WinPostMsg succeeds; WinSetDlgItemtext fails, as does WinSetWindowText.
-
- All my dialogs are loaded and started with WinDlgBox, with the owner
- handle set to NULL, so as to make them non-modal. The msg processing
- calls in main are the standard wingetmsg and windispatchmsg.
-
- I havent been able to find any special requirements in the docs
- for interaction of threads with dialog items, other than the general
- requirement of an anchor block handle. If you know of any
- special requirements or know where I might be screwing up, please
- E-Mail me.
-
- Thank you,
-
