WinDriver

Hi There,

Properly a really daft question but i am developing some code and am trouble with one specific function. It contains functions like WD_Open WD_License etc.

Is there any issue using these functions on a windows 7 professional machine?

Thanks
James

O_o

And do you have the library installed?

And a bazillion other questions I'm not typing out...

Code:

---

//    Open driver
    hWD = INVALID_HANDLE_VALUE ;
    hWD = WD_Open ( ) ;


    //    Exit if driver not opened
    if ( hWD == INVALID_HANDLE_VALUE )                            return ( 1 ) ;


    //    Set up version 7 license string
    BZERO ( lic ) ;
    strcpy ( lic.cLicense, "6f1ea8b419")  ;


    WD_License ( hWD, &lic ) ;


    //    Get version
    BZERO ( ver ) ;
    WD_Version ( hWD, &ver ) ;


    //    Exit if version incorrect
    if ( ver.dwVer < WD_VER )                                    return ( 2 ) ;

---

is the first part of my code.

it keeps saying the ver.dwVer = 0, and as a result retuning and not continuing with the code.

Any ideas as to why?

The library issue would appear with the above WD_Open wouldnt it?

You should use code tags for posting code

okay i been playing around and the WD License function isnt returning anything, it seems not to be going anything anyone any suggests where to start fault finding.

It does build but does nothing.

is it possible that i am using a 64bit machine be the problem?

Well, if it's this function, then a good read of the documentation there tells you:

Quote:

---

RETURN VALUE

Returns WD_STATUS_SUCCESS (0) on success, or an appropriate error code otherwise [A].

---

What is it returning? You say it "isn't returning anything", but I find that highly unlikely.

Code:

---

#define WD_License(h,pLicense)\
    WD_FUNCTION(IOCTL_WD_LICENSE, h, pLicense, sizeof (WD_LICENSE), FALSE)

---

is the definition of it and when i debug it, all the variables and structures associated with it come back as empty.

Maybe you should try their support channels?
