Hi, Am working on the displap driver for HP iPAQ. Presently i have written a pure wrapper class (myddi.dll) for HP iPAQ. (wrapper around ace_ddi.dll). The wrapper class has one DrvEnableDriver() function exported and this function inturn load ace_ddi.dll and other 24 functions implemented that dont do a thing other than just invoking the same functions of ace_ddi through function pointers and returning the appropriate values back. Next, i changed the HKEY_LOCAL_MACHINE\System\GDI\Drivers from ace_ddi.dll to my_ddi.dll so that GWES calls myddi.dll instead of ace_ddi.dll. And such a thing do happen.
BUT therez a problem... On software reset, the display is not refreshing after the status bar has reached the end. All the functions are called correctly except for DrvFillPath() function of the wrapper class is not called ..!!??!! i think this cud be the root cause of the problem .. but not sure ... Also not to mention, i can hear beeps if i tab on the PDA screen using a stylus...!!! but somehow i cant see the icons nor any menus. I tried a writting a exactly similar wrapper on Samsung PDA around ddi.dll and it works fine. I really wonder what could be the problem with HP.. Hoping to hear from you as soon as possible. Regards, Sriman
