    DWW-700H and equivalents Resume from Hibernation problem fix

    I bought an equivalent to the DWW-700H on ebay recently. I've posted comments in another thread on it, and made mention to a problem I had. The issue was that on resuming from hibernation, the touch screen did not work. No amount of messing with devcon helped, nor did changing the drivers for different versions, but I did find that if I ran the touchkit configuration program, as soon as it had read from the device during initialisation the touchscreen would work.

    Given it's a touch screen, running the config program manually after resume is impossible without a mouse or keyboard, so I decided to implement a software solution.

    resumelaunch sits in the background (put it in your startup group) and detects whenever the PC resumes from hibernation. When it detects this state it launches the configured application, waits for a configured number of seconds, then terminates it with a 'TerminateProcess' call.

    Software attached. Ini file contents should be self explanatory.

    I had a very similar problem.
    I dont use hibernation, but i was finding that after reboot the TS would not work unitil i ran the touchkit software.

    My solution (posted in a thread here) was to use the hard to find 3.2.3.3122 liliput drivers.

    try that, your program may not be needed....

    @Ric - Thanks for this - going to give it a go later - driving me mad.... Noticed too that the same problem happerns if you boot up if the screen is off.....

    Is there any way to introduce a periodic check as well as a power on check as well an option just to run rather than terminate as well ?

    ( Are you going to publish the code as well ( not a coder my self just wondering ? )

    @Hoss - I'm using those suggested drivers you mention... does not cure the problem as mentioned above but it does seem a little more reliable..

    Thanks

    I'm not developing at the moment, so won't be done by me.
