Title: NULL_BRUSH and TRANSPARENT
Post by: chrisc on March 18, 2018, 06:29:24 PM

Hello

when i try compiling a program with the below code
the compiler display an error message (shown in the atteched image)

Code: [Select]

   IF GetDlgCtrlID(lParam) = LabelFN THEN
                'wPARAM id device context DC
               SetTextColor(wPARAM, RGB(0,0,250))
               SetBkMode(wPARAM, TRANSPARENT)
               FUNCTION = GetStockObject(NULL_BRUSH)
               EXIT FUNCTION
      END IF                                 

the compiler found 2 unidentified objects   NULL_BRUSH  and TRANSPARENT
this must be caused by a missing include file

i have use CoreWin  what other include file shall i use?

Hi Chris,

% NULL_BRUSH=5
% TRANSPARENT=1

in OxygenBasic only the most used WinApi constants are defined. I use a small helper file, constructed of some C header files, but I think in Powerbasic these constants are defined somewhere too.

BTW: Dialogs.inc uses only the constants to run Dialogs.inc itself. So extra constants or types must be defined separately, if this is not already done somewhere else.

Hello Aurel and thanxx

yes i found some constants in ur awinh.inc,   is this the most correct one that contains all the API constants

can it be replacement of Corewin.inc  ?

 or can itwork with corewin.inc without duplicating each other?

hi chrisc
yes you can find many constants inside awinh.inc or awinh035.inc.

well for coremin.inc i am not sure , I use mine and what i found on web
sometimes i use MinWin.inc .

Also you can use both but for sure most constants are same...
You must know that I use awinh.inc for windows not for dialogs.
sorry i don't build Dialog Apps.  ::)

I'll add this set to WinData.inc (which is included in MinWin and CoreWin)

Code: [Select]

  % WHITE_BRUSH      0
  % LTGRAY_BRUSH     1
  % GRAY_BRUSH       2
  % DKGRAY_BRUSH     3
  % BLACK_BRUSH      4
  % HOLLOW_BRUSH     5
  % NULL_BRUSH       5

  % WHITE_PEN        6
  % BLACK_PEN        7
  % NULL_PEN         8
