My really out-of-date homepage Sonork-100.19012 Acid_Helm Question 2 - (threads and message pump) Nitron27-Jan-03 3:50 Nitron 27-Jan-03 3:50  So I have this application that does some data manipulation within a worker thread, and during lengthy operations, I like to post messages and update the GUI accordingly. Currently I am using custom WM_USER messages and using SendMessage() to the main thread. As I understand, SendMessage will wait for the message handler to return before going on, whereas PostMessage keeps on going. Also, I hear WM_USER is kinda outdated... Anyway, what is the best method of posting messages to update a gui from a worker thread that will avoid deadlocks or any messy stuff??

Note: The application isn't installed nor does it keep any info in the registry. It also may or may not be called by another application (which alters the working directory somehow). I ask because I have a data file I want to read in at runtime, and using ".\MyFile.dat" will work when I run the app within it's own directory, but when the other app calls it, ".\" is some other directory.

Hope this helps!

My reason for asking is that I have an object for each item in the tree, and I would like to maintain the handle within the object so that changes to it can be reflected easily in the tree (i.e. by changing the icon etc) Thanks in advance!

As far as I know a handle to a tree item should be valid during whole lifetime of the tree. I can't guess any situation in which the handle could be changed - especially as you can use it on any time for further operations like deleting, ...
