Version 2.65 Jul. 2009 Use this menu command to display the "Message handling" dialog box and set up message handling for the registered devices. On Windows 2000, Windows XP and Windows Vista, the user must have the administrative permissions in order to use this function. What is message handling? Some application needs to extract a message while a method requiring much time is being processed. In this case, use this command. If "Message is processed during synchronous" is selected, then OPOS methods or properties are not executed while an OPOS method requiring much time is being processed. (For example, during synchronization, if the Close method is executed, this may result in fatal errors such as causing the PC to hang.) "Message is not processed during synchronous" radio button Use this radio button to disable message handling. "Message is processed during synchronous" radio button Use this radio button to enable message handling. When this button is selected, a warning message box appears; when choosing the [Yes] button, the "Message is processed during synchronous" radio button is then selected and message handling will be performed. [OK] button Close the dialog box and save the current settings. [Cancel] button Use this button to cancel the setting and close the dialog box. [Help] button Use this button to display the help on the dialog box by clicking this button. v. Setting Sleep Time Use this menu command to display the "Setting Sleep Time" dialog box and set the Sleep time of Win32 API. In the programs for waiting for input from device inside the driver or long processing programs, to keep the CPU time use exclusively, EPSON OPOS ADK calls Sleep (a WIN32 API) and specifies the time to pass control to other programs. 88 User's Manual Installer, SetupPOS, TMUSB
