[power-pro] pointer to string

[cronus1974]

Dear all:

Is DLL plugin the only tool to play with pointer?

I want to retrieve some text info from an application (In fact, the track info 
from Jaangle player). The application provided the api, the info can be 
accessed by 
SendMessage(targetHWND, WM_GETTEXT, (WPARAM)bufLen, (LPARAM)strbuf)

strbuf is an LPTSTR， which I dunno how to define in powerpro. I guess I 
should help the from dll plugin, but it is the first time I use it.
Any suggestions will be appreciated?

Thanks!
