Exception in Init() C# code:

[apurv.purohit]

Sometimes I used to get “Exception in Init()” in my code….which results restart in application or restart of EPSON PLQ22 device….following is the exception:

Exception in Init(): System.AccessViolationException: Attempted to read or write protected memory. This is often an indication that other memory is corrupt.
at SP_EPSON_PLQ22.Twain.DSMparent(TwIdentity origin, IntPtr zeroptr, TwDG dg, TwDAT dat, TwMSG msg, IntPtr& refptr)
at SP_EPSON_PLQ22.Twain.Init(IntPtr hwndp)

Once the exception has occurred, USB doesn’t releases the resources…and that might be the cause of restarting an application….

Hi,

Did you try to turn off the DEP (Data Execution Prevention)?
