The operating system is win7x64, when using x64 application and driver communication, no problem, right! When using the x86 application and driver communication, blue screen directly, estimation is a problem of data communication, data communication with the int and dword type, request bosses support, how to solve this problem? For several days

Handles the communications code or post code, can also take a look at the dump file system

like this, should be the exception stack area, alas, want to have a com interface, indirect invocation, x64com, however, failed to create object by id

CodePudding user response:

Drive communication don't understand, though, x64 and x86 communication especially need to pay attention to data of digits, such as int of four in x86, x64 inside of 8 bits, so define communication standard, try to distinguish with int32 and int64

don't know much about the driver communication, however, x64 and x86 communication especially need to pay attention to data of digits, such as int of four in x86, x64 inside of 8 bits, so define communication standard, try to distinguish with int32 and int64

yes, but the end will go wrong
