Can you compile SC without the SystemHook DLL selected.

Post by kenray »

Is it possible to do an on-line compile of single click without the SystemHook DLL option as default? When unchecked the SC works great with our custom app as well as all Windows versions. As a work around we have found that after the SC server connects to a viewer, we can remotely open the SC server properties from the tray and un-select the system hook. As long as we apply without OK the session has great response. If you select OK it goes back to the default.

I also have this same issue. As soon as we uncheck that box we can view everything. Is there a config file or anything I can add to disable this option?

Thanks for any help or info

I made a install set without the dll even in it and still had the same issue until I unchecked the System Hook dll option on the remote pc.

Hi,
you can open sc.exe using 7-Zip and rename SCHook.dll
Unfortunetaly Vista and friends show "unknown issuer".

Or use "7-ZIP SFX Maker" to create the sc.exe yourself.

Does anyone know if there is a switch (like -disablehook) to disable SCHook.dll?

Thank you very much

I would have thought it would work fine just be removing the DLL. At least in SCPrompt and ChunkVNC (which use the full version of UltraVNC) the software seems to gracefully ignore the absence of the hook and other optional DLLs... ?

If the dll doesn't exist, it isn't used.
Does 7zip allow to delete the file from the sfx archieve ?

Does anyone know whether this issue has a solution. On Windows 7 I have found 3 programs so far where the viewer freezes unless the option to not use system hook is selected manually. (Firefox, Spybot 1.6, Windows DVD Maker)

Ah looks as if you've found the right thread. As Rudi suggested, go ahead and try using 7-Zip to simply delete the DLL file from the EXE file (the one the SC creator makes) and see if it works.

Tested the schook.dll, seems that
AccessibleObjectFromEvent call ( This is a standard MS Accessiblity call)
cause the schook to hang when Firefox start .... crazy.
Seems only be the case when object is created.... removed position hint when object is created and no more hang.

online creator updated with new file... please test

Rudi, I just tested your new online creator against WIN7 Home Premium.

The Firefox issue where it freezes the viewer is now working. Congrats.

Unfortunately there are two "howevers".

1. Spybot 1.6.2 still exhibits the problem . Clearly Firefox is more important but this suggests there are one and possibly more programs that will defeat the fix you made. Sorry. (Note: This problem also occurs with SC running on XP. Don't recall whether it did before.)

2. I generated the test SC file using the [WALLPAPER] option. At immediate connect I saw the wallpaper but then it quickly turned to a black background. Any chance your change caused this? Probably well worth someone else testing this.

Thanks and good luck ... Sam

Only change is schook.dll, this doesn't have animpact on wallpaper and other.
Schook.dll just give hints about the screen changes..
