 | who C knows, knows too The Header-Files, there üblicherweise with the Endung .h. One ähnliches concept watts now too in XProfan verwirklicht, here with the Endung .ph. around the Headerdatei(en) anzugeben, The in the program used go, uses one The Direktive $H:
$H windows.ph
The XProfan-Header-Files (*.ph) go there sought, where too The Include Files sought go. The attitude the Includepfades counts too for Header.
The Header-Files are nothing other as Übersetzungstabellen. defined expressions in the Programmtext, The there through one ~ marked are, go through others of Precompiler at reading the Program by the Interpreter or. Compiler supplant. On these point can z.B. The numerous Konstanten, Strukturdefinitionen and API-Aufrufe in the Headerdatei described go. Each row the Headerdatei has to the Gleicheitszeichen whom String the supplant go should and thereafter until last Semikolon the row whom XProfan-expression, by the it supplant becomes.
as example one Headerdateiauszug from WINDOWS.PH:
' Konstanten for ShowWindow
SW_HIDE = 0;
SW_SHOWNORMAL = 1;
SW_NORMAL = ~SW_SHOWNORMAL; ' old shape
SW_SHOWMINIMIZED = 2;
SW_SHOWMAXIMIZED = 3;
SW_MAXIMIZE = ~SWSHOWMAXIMIZED;
SW_SHOWNOACTIVATE = 4;
SW_SHOW = 5;
SW_MINIMIZE = 6;
SW_SHOWMINNOACTIVE = 7;
SW_SHOWNA = 8;
SW_RESTORE = 9;
SW_SHOWDEFAULT = $0A;
SW_MAX = $0A;
ShowWindow( = External("user32.dll","ShowWindow",;
comments go - How in XProfan self - through one ' marked, the REM isn't allows. what between Gleichheitszeichen and the last Semikolon standing, must in XProfan interpretierbar his. it can though against Ersetzungsausdrücke, marked by the ~, vorkommen.
the dazugehörige XProfan-Program could then How follows looks:
$H windows.ph
Cls
~ShowWindow(%hWnd, ~SW_MAXIMIZE)
likewise can Strukturdefinitionen in a Headerdatei untergebracht go:
RECT = Top&,Left&,Right&,Bottom&;
in the Program could then stand:
Declare rectangle#
Struct TRECT = ~RECT
Dim rectangle#,TRECT
With rectangle#
.Top& = 10
.Left& = 120
.Right& = 35
.Bottom& = 100
EndWith
herewith are The Opportunities the Header-Files only ansatzweise implied! an Umsetzung the File WINDOWS.PAS from Delphi with almost all Definitionen the Windowskonstanten and -functions lying with. likewise some others Header-Files with Messages, Structures, etc. If these Files eingebunden are, becomes The Use the windows-API vastly vereinfacht. but too outside the Use stranger DLLs yield itself numerous Opportunities.
alas Yes: The benefit the Headerdatei to of/ one Includedatei with Konstanten and DEFs? The Includedatei becomes always complete mitkompiliert and vergrößert the finished Program. The Headerdatei diving in the Compilations ÜBERHAUPT NOT on. any Ersetzungen go at Compilieren directly undertaken. the might itself too very positively on The Ausführungsgeschwindigkeit work out. For this lasts the started in the interpreter mode and the Compilieren something longer.
Info: The in a structure verwendeten Variablentypen go through your Postfix, similar the XProfan-variables marked. % standing for a 2-byte-Variable (Word), & standing for a 4-byte-Variable (Long), # standing for a arbitrary Size, The in clinging indicated becomes, and $ for a String-Variable. Particulars see here! the "H" (Compilerschalter $H) must big written his!
