Do you people who program with Windows use SendMessage and PostMessage a lot? Or are these things that you CAN do, but there is no real need for them a lot.

"Hello!!?? Windows Board??!?"
Yeah, I use SendMessage a lot to communicate with controls.....PostMessage not as much
I think the only difference between the two is that SendMessage blocks while PostMessage returns immediately. But yes, used quite a lot...
Messages are a way of allowing communication between different processes, running in different threads. The Windows message API may seem complicated, but I don't see a better way of doing things.
All (non-console) windows applications use messages at some level. How do you think mouse movements, mouse clicks, key presses are forwarded to the application?
Personally, I use Borland BCB, which hides alot of the implementation of messages. However, underneath its just handling messages for me.
Without the SendMessage API call... thr would be no abillity to totally mess up window objects and make em look like all kind of wierd controls at runtime.... think of the lack of fun you would have :) or am i the only one who is sad enough to send buttons loadsof wierd messages making em act like text fields :?
True but not solely. It also allows your app to communicate with it's own objects in a non-blocking way. That is, were you to just manipulate a control directly, you would slow down the "multitasking" feel of your app. By sending messages, you are in a sense making your program multithreaded from within itself...Quote:

Finally, console apps too are actually windows programs in disguise, and so they use the Windows message system just as heavily (unless compiled as DOS apps - my compiler won't even do that!).
And Microfiend, yes, you are the only one :D
lol uhh, I don't think I've ever used either one of those functions... is that a bad thing, or is it just something I'll have to grow into? (like eating vegetables, for example :D)
I also tend to use the macros for specific types of controls from commctrl.h
ie
ListView_GetItemCount() instead of SendMessage and LVM_GETITEMCOUNT
Use both all the time.
