Hi Igor,
in Win32 often one passes NULL as argument
(for instance if a function has an argument "handle to a window", then
a hWnd of NULL can be given).
For instance when I have
shellExecute: hwnd operation: lpOperation file: lpFile parameters:
lpParameters directory: lpDirectory show: nShowCmd
<primitive: #primitiveNativeCall module: #NativeBoostPlugin>
^ self nbCall: #(
HINSTANCE ShellExecuteA(
HWND hwnd,
LPCTSTR lpOperation,
LPCTSTR lpFile,
LPCTSTR lpParameters,
LPCTSTR lpDirectory,
INT nShowCmd)) module: 'Shell32.dll'
The NBFFICallout class(NBNativeCodeGen class)>>handleFailureIn:nativeCode:
tells me that "an instance of NBWin32Window" is expected.
So currently I have to pass "NBWin32Window getFocus" as first
argument. But often this is not necessary.
I also havent found a constant pool with NULL or an accessor.
Whats the prefered way to deal with NULL in NB?
Can you also please add me as a developer
to http://www.squeaksource.com/NativeBoost
My initials are "tbn"
I would like to add several API functions for
Win32 (ShellExecute, OutputDebugString, ...)
Thx
Torsten
