• whitegrs O/R mapper requirements for domain layer

  I have heard a lot of talk about disadvantages of various ORM solutions.  Mainly that some use attributes and reflection, making your domain layer peppered with hints about how objects are serialized and complaints (probably false) that reflection is slow.  Also, some frameworks don't support caching of domain objects.  Some require you to derive all your domain classes from a base class provided by the mapper.  Others can't ...Show All

• sanjak XP or XPE for POS application

  Hi, Not sure if this is the correct place to post this - apologies if it's not. I'm developing a custom POS application in VB.Net 2.0 for no more than 4 terminals.

Because of the limited number of clients, it would be more expensive to buy t ...Show All

• Keshaba ActiveX in autoproxy script in XP SP2.

  We are using a javascript for our Autoproxy, but because of a legacy problem with how our domains were configured, we need to determine the Active Directory Domain of machines to know which proxies to send them to. The following code worked great in XP SP1, but we are testing in XP SP2, and it's failing. This would run in the "Local Intranet" security zone in IE, where all ActiveX is allowed and enabled. Anyone have any ideas on how t ...Show All

• Bob ONeill How can I prevent the Wisptis.exe driver from using a specific device?

  The Wisptis.exe driver uses any HID digitizer it finds. This is causing problems with our software. Our software can’t open the HID digitizer exclusively because we have to jump thru hoops to get around patent issues. I need a way to tell the Wisptis.exe driver not to using a specific device. I know the registry keys where the Wisptis.exe driver stores the device info. HKEY_CURRENT_USER\Software\Microsoft\Wisp\Pen\Persist ...Show All
