问题 I'm developing an application in C# for symbol PPT2800 barcode scanner. I'm almost done but there is one last thing I need, I want the scanner to disable the beep if the ean code was not found and make a different sound. I've been tearing my hair over this but I cant get it to work, could someone help me? 回答1: You need to either find the Symbol SDK (I think Motorola bought them out) or go into the Settings for the Scanner and turn the audible beep option OFF.

问题 How to obtain a Motorola (Symbol) Mobile Device Serial Number? I'm programming the Motorola ES400 which comes with "Symbol" libraries. There seems to be ways of getting the serial numbers of the various scanners, but not of the actual device itself! Anyone got any ideas?

问题 How do I detect when my Compact Framework application is being smart-minimized (smart minimize is what happens when the user clicks the "X" button in the top-right corner on a Pocket PC)? The Deactivate event isn't the right way because it occurs in circumstances other than minimization, such as when a message box or another form is shown on top of the main form. And the form's WindowState doesn't help because there is no "Minimized" WindowState on .NET CF. I heard that by setting MinimizeBox
