Q: How can I initiate a touch panel calibration through software?
See the update below for current recommendations.
There are several ways to do this. For portability of your application across ADS builds of CE, we recommend that you call \windows\ForceCal.exe.
For further reading about touch panels on ADS products, see the touch panel topic index.

Edited 27-dec-2002 by akidder: Update \windows\calibrate.exe to \windows\ForceCal.exe. Remove requirement that "CalibrationData" registry key from [HKEY_LOCAL_MACHINE\HARDWARE\DEVICEMAP\TOUCH] be deleted.
Edited 7-Dec-2006 by akidder: Strike ForceCal information and refer to link below. |

BitsyX 4.10.23, 1.07
Changed all CreateProcess calls from \windows\calibrate.exe to \windows\ForceCal.exe. CreateProcess returns error code 0x2 - ERROR_FILE_NOT_FOUND |

#TouchCalibrate
Update: TouchCalibrate() API
Instead of calling ForceCal.exe, it is often simpler to just call the system TouchCalibrate() API, which will present the calibration screen. TouchCalibrate is exported by coredll.dll and can be easily added to your code like this:
// declaration
extern "C" BOOL TouchCalibrate(void);
...
//use
TouchCalibrate();

Hello:
When using TouchCalibrate(), does it automatically persist the new registry settings for the touchscreen, or should one programatically flush the registry?
Thanks |

| Persistence is automatic. Older systems save to adsload.reg; newer CE builds will save calibration to the hive-based registry. |

| Calibration data was stored in ADSLOAD.REG only in older systems. In your newer system, a new calibration can't be forced from ADSLOAD.REG. To force a new calibration, put an application into one of the \Startup folders. Sample code can be found at Topic 1004. |

Linda,
Please define 'newer system'. Where is the cutoff point? Which systems/boards? I'm not only concerned with the boards that we are currently using, but also any to which we may consider migrating.
Thank you. |

| The switchover from RAM-based to Hive-based registries occurred during 2005. See Topic 1469 for general details. You can also look at the CE files page for specific devices of interest. |

To clarify you can look at your system to determine if it is using HIVE registry.
If your system has the "FlashFX Disk\Documents and Settings\" folder, then it includes HIVE registry and would fall under the 'newer system' for this discussion. |
