whats gwl_exstyle....
and
Private Const GWL_STYLE = (-16)
Private Const GWL_EXSTYLE = (-20)
Private Const WS_EX_LAYERED = &H80000 ???


am new to use of api in VB6.0
but they seem to b the most powerful tool in VB as front end....

using them for form transparency and other effects i came across the above mentioned things.....searched the forum and whole net but didnt find a clue why we use WS_EX_LAYERED = &H80000 ....
would be great if some one could list the whole list of such constants or tell where to learn from!!!

similarly even in MSDN for VB6.0 they have not explained the state on winsock...and working on winsock becomes so difficult if VBForum was not here.....how each state is achieved is very difficult to know if you dont know them before hand!
