but by some reason i can't change the backcolor and textcolor :(
i even try these: http://www.winprog.org/tutorial/dlgfaq.html
but without sucess :(
please tell me what you know



Moderator: i have found 1 error on these forum... the thread have more than 1 pages, and i have send a big text... but the text was too long, so i recive the error message. until here normal. but why goes to the 1st page and continue with page 2 selected???
for resolve these, i must select the 1st page(because is unselected) and then i click on page 2.
(in these situation, the refresh of the browser don't resolve it)

controls dont RECIVE WM_CTLCOLOR.... messages they SEND them to there parent
not sure i think after they recive a NM_CUSTOMDRAW

i think i was try something similair to you but it wont work out
its easier to make a NEW label control then use the win own
in this way you get no additional control over the control you just ending
whit a big mess
in this case you need to figure out where the "label" holds its color informations
and set it there
Cambalinho (1445)
now i know why isn't working:
the WM_CTLCOLORDLG or WM_CTLCOLORSTATIC are reciving from main window.
but it's there another message that i can use it?
xeef (26)
no

just think on it

what message would that by ?

hi i am your parent window your color is red and stored in address xxxx nice to
contact you bey



Edit

just the label nows its color and where its stored so he cant recive a message whit this info unles from it self wich would by senseless as he already knows

now have 1 big problem with my class(too big for put the code :().
can i put the window procedure inside the class without use the 'static' keyword? :(
modoran (2077)
No, if WndProc is member of a class, then it must be a static member.
Cambalinho (1445)
i'm getting several problems with instances\objects because of that :(
Cambalinho (1445)
heres the entire class: http://ideone.com/1fQEmp

my problem is only with instances, but the code works(except these one that i'm trying to fix) :(
