Hello,
I am trying to implement the IURLSearchHook2 interface in comtypes and I
am running into some issues.
According to MS the only method in the interface is this:
(http://msdn.microsoft.com/en-us/library/bb774478(VS.85).aspx)
IURLSearchHook2::TranslateWithSearchContext Method
Called by the browser when the browser cannot determine the protocol of
a URL address. This method uses a search context to determine the
protocol.
Syntax
HRESULT TranslateWithSearchContext(
LPWSTR lpwszSearchURL,
DWORD cchBufferSize,
ISearchContext *pSearchContext
);
Parameters
lpwszSearchURL
[in] The address of a wide character buffer that, on
entry, contains the URL address for which the browser is trying to
determine the protocol. On exit, this buffer contains the modified URL
address if the method was successful.
cchBufferSize
[in] The size, in characters, of the buffer at
lpwszSearchURL.
pSearchContext
[in] A pointer to an ISearchContext
<http://msdn.microsoft.com/en-us/library/bb775199%28VS.85%29.aspx>
object.
Return Value
Returns S_OK if successful, or an error value otherwise.
I have been unable to locate a MS idl or tlb for this interface, however
I found one that Wine supplies:
// IUrlSearchHook2 Interface
[
object,
uuid(5ee44da4-6d32-46e3-86bc-07540dedd0e0)
]
interface IURLSearchHook2 : IURLSearchHook
{
HRESULT TranslateWithSearchContext([in, out] LPWSTR lpwszSearchURL, [in]
DWORD cchBufferSize, [in] ISearchContext * pSearchContext);
}
which generate the following in the comtypes.gen .py files:
class IURLSearchHook2(IURLSearchHook):
_case_insensitive_ = True
_iid_ = GUID('{5EE44DA4-6D32-46E3-86BC-07540DEDD0E0}')
_idlflags_ = []
IURLSearchHook2._methods_ = [
COMMETHOD([], HRESULT, 'TranslateWithSearchContext',
( ['in', 'out'], WSTRING, 'lpwszSearchURL' ),
( ['in'], c_ulong, 'cchBufferSize' ),
( ['in'], POINTER(ISearchContext), 'pSearchContext' )),
]
################################################################
## code template for IURLSearchHook2 implementation
##class IURLSearchHook2_Impl(object):
## def TranslateWithSearchContext(self, cchBufferSize,
pSearchContext):
## '-no docstring-'
## #return lpwszSearchURL
##
I can get the data into the method and print it out fine.
The problem is when I try and return a string out. It just plain hangs.
If anyone has any thoughts. Is this even possible?
I have tried both the "high level" and "low level" approach as discussed
in Thomas' recent post
class LILWSearchHook(AGCoreLib.AGSearchHook):
_reg_threading_ = "Both"
_reg_progid_ = "AGCoreLib.AGSearchHook.1"
_reg_novers_progid_ = "AGCoreLib.AGSearchHook"
_reg_desc_ = ""
_reg_clsctx_ = comtypes.CLSCTX_INPROC_SERVER |
comtypes.CLSCTX_LOCAL_SERVER
#High Level sample
def TranslateWithSearchContext(self, lpwszSearchURL, cchBufferSize,
pSearchContext):
logger.info('Got a search request %s' % lpwszSearchURL) #logs whatever I
supplied in search box
logger.info(type(lpwszSearchURL)) #logs unicode
logger.info(dir(lpwszSearchURL))
#return "http://cnn.com <http://cnn.com> "
return c_wchar_p(http://cnn.com)
#Low Level sample
def TranslateWithSearchContext(self, this, lpwszSearchURL,
cchBufferSize, pSearchContext):
logger.info('Got a search request %s' % lpwszSearchURL) #logs whatever I
supplied in search box
logger.info(type(lpwszSearchURL)) #logs unicode (I was expecting a
ctypes data type)
logger.info(dir(lpwszSearchURL))
lpwszSearchURL[0] = "http://cnn.com <http://cnn.com/> "
return S_OK
Thanks for your help,
Mike
