There are two binary files (CondMgr.dll and HsApi.dll), required by the Palm
Conduit Installer, which are provided by Palm and Palm provides free
redistribution license for them. However since these binaries are not "open
source" it is advisable to rather not use them for redistribution as part of

The install code loads redistributable copies of these binaries to find the Palm
software (HotSync stuff) path and then install the palm conduit, the right thing
to do as per Palm documentation. But we need to change this.

If the user has a Palm handheld and installs the HotSync stuff that comes with
it, it is very likely that these binaries will exist on the users machine.
I have found a Registry key that seems to exist on machines where the Palm
software is installed. I have changed the code to use this registry key to find
the Palm software path and load these 2 dlls from the Palm software location
thus avoiding the need to redistribute them.

Also the PalmSync support module is not yet added in the installer manifest and
registration of Mozilla Palm sync support proxy is currently needed to be done
by hand. So the first needs to be done and the Conduit Installer needs to do
registration and unregistration of support proxy during conduit install and

In general it's better to use sizeof(<buffer>) when possible to avoid changing
one definition and forgetting to catch the others. Note that if
szPalmDesktopDirectory was somehow larger than the _MAX_PATH value you pass in
the resulting string would not be null terminated.

>     strncat(szPDCondMgrPath, CONDMGR_FILENAME, _MAX_PATH-strlen(szPDCondMgrPath));

Similar issues here. Maybe you could do _snprintf("%s%s%s",_MAX_PATH, ...)
instead. Check for a negative return value to see if you overflowed, or just
always slap a null in the last character of the buffer.

>+    if( (*hCondMgrDll=LoadLibrary(szPDCondMgrPath)) != NULL )
>+        // Successfully loaded CondMgr Library from Palm Desktop Directory
>     return 0;

The indentation here is confusing. I assume return 0; should be indented?

>+    if( (hMozPalmSyncProxyDll=LoadLibrary("PalmSyncProxy.dll")) != NULL ) {

Could you use a full path here? It's a pretty generic name, I'd hate to pick up
the wrong one from the windows path if ours wasn't installed for some reason.

Verified code fix. Rajiv, I'm assuming it's working as desired. ???
QA Contact: bugzilla → ktrina
Why is this "Verified code fix"? this should be testable by anyone able to test
the Palm feature in the first place.

Well, then can someone with a Palm give this a go?
