application messaging

Krauze

I'm currently coding on a project where I need to post a user-defined message together with a LPCWSTR parameter. But I don't know how to achieve that coz you know, PostMessage() only provides parameters typed as WPARAM and LPARAM. Anyone could help? Many thx in advance.

Cast[^] your string to LPARAM and do the reverse at the receiving end.

but be aware that if your string is transient ((new'd and delete'd) or stack based), it'll possibly be corrupt at the other end if you PostMessage it ...

I'm well aware of that. However, if the OP is not aware of casting then I doubt he'll be into something as advanced as new and delete. ;)

Let's hope both the sending and receiving end is in the same process-space.

How so? In order to pass strings from one thread to another using PostMessage(), new and delete are highly recommended.
