Hi,
I've tried to add ActiveX to my plain WinAPI Hello world sample. I
needed to add *TWO* lines (marked by /* !!!*/) below and #pragma
begindump/enddump. THAT'S ALL! I understand that event handler is
missing and OleAutomation object should be created, but this is not so
much code. I have a feeling, that if I'll do some ActiveX support, I'll
do that starting from zero, instead of trying to analyse all current
code. WARNING: The bad side will be that my code could be not compatible
to existing one, the good one is that it will be simple and clear.
===============================================
#include "c:\cawi32\include\windows.ch"
REQUEST HB_GT_NUL_DEFAULT
FUNC main()
LOCAL nAddr, hWnd, cMsg
AtlAxInit() /* !!! */
nAddr := MakeWndProc({|X,Y,Z,T| WndProc(X,Y,Z,T)})
RegisterClass("MainWndCls",, COLOR_WINDOW + 1, LoadCursor(EMPTYPTR(),
IDC_ARROW), LoadIcon(EMPTYPTR(), IDI_APPLICATION),,,, nAddr)
hWnd := CreateWindow("MainWndCls", "CAWI32 Sample Hello",
WS_OVERLAPPEDWINDOW, 100, 100, 600, 500)
ShowWindow(hWnd, SW_SHOWNORMAL)
UpdateWindow(hWnd)
DO WHILE GetMessage(@cMsg)
TranslateMessage(cMsg)
DispatchMessage(cMsg)
ENDDO
RETURN 0
FUNC WndProc(hWnd, nMsg, wParam, lParam)
LOCAL hDC, sPS, hMenu, hSubMenu
IF nMsg == WM_CREATE
CreateWindow("ATLAXWin", "http://www.harbour-project.org";, WS_CHILD
+ WS_VISIBLE + WS_BORDER + WS_HSCROLL + WS_VSCROLL, 10, 10, 500, 400,
hWnd) /* !!! */
ELSEIF nMsg == WM_PAINT
hDC := BeginPaint(hWnd, @sPS)
EndPaint(hWnd, @sPS)
ELSEIF nMsg == WM_DESTROY
PostQuitMessage()
RETURN 0
ENDIF
RETURN DefWindowProc(hWnd, nMsg, wParam, lParam)
PROC RDDSYS(); RETURN
PROC HB_GTSYS(); RETURN
#pragma begindump
#include "hbapi.h"
#include <windows.h>
static HMODULE hLib = NULL;
HB_FUNC( ATLAXINIT )
{
BOOL ( CALLBACK *pAtlAxWinInit )( void );
hLib = LoadLibrary( "atl.dll" );
if( ( unsigned long ) hLib > 32 )
{
pAtlAxWinInit = GetProcAddress( hLib, "AtlAxWinInit" );
if( pAtlAxWinInit )
( *pAtlAxWinInit )();
}
// I leave hLib not freed to avoid unloading of library
}
#pragma enddump
===============================================
You'll not be able to compile it, but all function are straight wrappers
of WinAPI (MakeWndProc() is an exception, it registers codeblock and
returns window procedure address). So, I hope you'll be able to create
ActiveX control in your environment, if you have idea how to create a
window in it and access hWnd.

Mindaugas
