All rights reserved. DOCUMENT CONTENTS ----------------- This document supplements the information in the Near Field Imaging Touch Screen System Software User's Guide. This document contains the following sections: 1. Description of files on the Diskette/CD-ROM 2. Touch Screen Configuration Import/Export Utility 3. Developer Touch Error Detection 1. Description of files on the Diskette/CD-ROM ---------------------------------------------- The installation diskette/CD-ROM contains all the files needed to install the touch screen software for Windows NT 4.0. Once you have installed the software, you may use the full touch screen capabilities of the NFI touch screen controller. The installation diskette/CD-ROM contains the following files: INSTALL.EXE - Installation utility README.TXT - This file DISK1 - Identifies this CD-ROM for Windows NT setup EDTCNT.SYS - Kernel mode touch screen driver EDTCNT.INF - Installation script used by Windows NT 4.0 TOUCHCFG.EXE- Touch screen Configuration Utility executable TOUCHCFG.HLP- Touch screen Configuration Utility help file TOUCHCFG.LNK- Start menu shortcut to Configuration Utility TOUCHINI.EXE- Touch Screen Configuration Import/Export Utility TOUCHERR.DLL- Touch screen developer error detection DLL TOUCHOSI.DLL - Touch screen DLL MBSWAP.EXE - Mouse button swap utility executable MBSWAP.HLP - Mouse button swap utility help file MBSWAP.LNK - Start menu shortcut to button swap utility NSD.EXE - NFI Setup and Diagnostic Utility executable NSD.LNK - Start menu shortcut to NFI Setup and Diagnostic Utility NFISETUP.EXE - NFI Setup Wizard executable NFISETUP.LNK - Start menu shortcut to NFI Setu Wizard MSVCRT40.DLL- Touch utilities DLL XNMBA458.DLL- Touch utilities DLL XNMHN458.DLL- Touch utilities DLL XNMTE458.DLL- Touch utilities DLL UNINSTAL.EXE- Uninstallation utility UNINSTAL.INF- Uninstallation script file 2. Touch Screen Configuration Import/Export Utility --------------------------------------------------- To generate a configuration file that can be copied and imported on other computers, use the Touch Screen Configuration Import/Export Utility (TOUCHINI.EXE). This eliminates the need for configuring each unit manually. The Touch Screen Configuration Import/Export Utility is automatically installed when you install the touch screen drivers and utilities. This utility is copied to the \TOUCH\NT folder on your computer's hard disk. Exporting button definitions ---------------------------- To export configuration settings from the registry to a file: 1. In the Start menu, select Programs, then select Command Prompt. 2. At the command prompt, type CD\TOUCH\NT 3. Type TOUCHINI /o where o = output. This creates a file with the default file name TOUCH.INI. This file contains an ASCII representation of the touch screen configuration. 4. To change the file name, specify a new file name after the /o parameter. For example, if you type TOUCHINI /oCONFIG.INI, the configuration file will be named CONFIG.INI, in the \TOUCH\NT folder. You can use this file to import the same configuration into other units. Importing button definitions ---------------------------- When you import a configuration file, the existing settings are erased. To import configuration settings into the registry from a file: 1. In the Start menu, select Programs, then select Command Prompt. 2. At the command prompt, type CD\TOUCH\NT Type TOUCHINI /i<filename> where <filename> is the file you created in either step 3 or step 4 of the procedure for exporting button definitions. See Exporting button definitions above. The new configuration takes effect the next time you start Windows NT. 3. Developer Touch Error Detection ---------------------------------- Application developers can use the supplied DLL "toucherr.dll" to detect touch screen and controller errors during startup. The DLL provides a single function that reads startup errors from the registry and returns the error string to the caller. Interface Specification: function - TouchGetErrorLogString The TouchGetErrorLogString function retrieves the data for the touch error log value associated with the DYNAPRO registry key. LONG TouchGetErrorLogString ( CHAR *pszBuffer, LONG *pnBufferSize ) Parameters: - pszBuffer Pointer to a buffer that receives the value's data. This parameter can be NULL if the data is not required. - pnBufferSize A pointer to a variable that specifies the size, in bytes, of the buffer pointed to by the pszBuffer parameter. When the function returns, this variable contains the size of the data copied to pszBuffer. If the buffer specified by pszBuffer is not large enough to hold the data, the function returns the value ERROR_MORE_DATA, and stores the required buffer size, in bytes, in the location variable pointed to by pnBufferSize. If pszBuffer is NULL, and pnBufferSize is non-NULL, the function returns ERROR_SUCCESS, and stores the size of the data, in bytes, into the variable pointed to by pnBufferSize. Return Values If the function succeeds, the return value is ERROR_SUCCESS. If the function fails, the return value is an error code as defined in WINERROR.H. Sample Application Code: The following is a sample of code used to access the DLL and retrieve the ErrorLog Value: /* declarations */ typedef LONG (CALLBACK* LPFNDLLFUNC)(CHAR *,LONG *); #define nERRORLOG_SIZE_MAX 1024 ... LONG YourErrorCheckFunction() { CHAR szValueBuffer[nERRORLOG_SIZE_MAX]; LONG nValueBufferSize = nERRORLOG_SIZE_MAX; LONG status = ERROR_SUCCESS; HINSTANCE hDLL; /* Handle to DLL */ LPFNDLLFUNC lpfnDllFunc; /* function pointer */ hDLL = LoadLibrary("TOUCHERR.DLL"); if (hDLL != NULL) { lpfnDllFunc = (LPFNDLLFUNC) GetProcAddress(hDLL,"TouchGetErrorLogString"); if (!lpfnDllFunc) { /* handle error */ status = ERROR; } else { /* call the function */ status = lpfnDllFunc(szValueBuffer,&nValueBufferSize); /* Buffer now contains error message if any */ } FreeLibrary(hDLL); } return status; } --------------------------------------------------------------------- For more service and technical information in Canada and the USA, call Dynapro at 1-800-667-0374; for service and technical information outside Canada and the USA, call Dynapro at 1-604-521-3962.Download Driver Pack
After your driver has been downloaded, follow these simple steps to install it.
Expand the archive file (if the download file is in zip or rar format).
If the expanded file has an .exe extension, double click it and follow the installation instructions.
Otherwise, open Device Manager by right-clicking the Start menu and selecting Device Manager.
Find the device and model you want to update in the device list.
Double-click on it to open the Properties dialog box.
From the Properties dialog box, select the Driver tab.
Click the Update Driver button, then follow the instructions.
Very important: You must reboot your system to ensure that any driver updates have taken effect.
