I have been trying get this m-file supplied at hackhole.blogspot.com/2007/11/in … -with.html to work. It is returning the following error:

[code]Channel (0-3): 0
Status:Warning: Warnings messages were produced while parsing. Check the functions you
intend to use for correctness. Warning text can be viewed using:
[notfound,warnings]=loadlibrary(…)

In loadlibrary at 394
In K8055_Connect at 8
Error loading library intermediate output follows.
The actual error is at the end of this output.

I’m running Windows 7 64-bit Ultimate and Matlab r2009b 7.9 and visual studio 2008 sp1
I have tried using the updated .dll and .h files that velleman provieds and still no luck.

Any help would be appreciated. Thanks

I have the same problem, so i can’t help. But if you solved the problem by now i really like to hear about it. :slight_smile:

This problem looks similar as in this thread:
viewtopic.php?f=3&t=3787&

The solution was to change in the .h file all the

FUNCTION __stdcallto

FUNCTION void __stdcall

You may try this one:

[code]
#ifdef __cplusplus
extern “C” {
#endif

#define FUNCTION __declspec(dllexport)

FUNCTION long __stdcall OpenDevice(long CardAddress);
FUNCTION void __stdcall CloseDevice();
FUNCTION long __stdcall ReadAnalogChannel(long Channel);
FUNCTION void __stdcall ReadAllAnalog(long *Data1, long *Data2);
FUNCTION void __stdcall OutputAnalogChannel(long Channel, long Data);
FUNCTION void __stdcall OutputAllAnalog(long Data1, long Data2);
FUNCTION void __stdcall ClearAnalogChannel(long Channel);
FUNCTION void __stdcall ClearAllAnalog();
FUNCTION void __stdcall SetAnalogChannel(long Channel);
FUNCTION void __stdcall SetAllAnalog();
FUNCTION void __stdcall WriteAllDigital(long Data);
FUNCTION void __stdcall ClearDigitalChannel(long Channel);
FUNCTION void __stdcall ClearAllDigital();
FUNCTION void __stdcall SetDigitalChannel(long Channel);
FUNCTION void __stdcall SetAllDigital();
FUNCTION bool __stdcall ReadDigitalChannel(long Channel);
FUNCTION long __stdcall ReadAllDigital();
FUNCTION long __stdcall ReadCounter(long CounterNr);
FUNCTION void __stdcall ResetCounter(long CounterNr);
FUNCTION void __stdcall SetCounterDebounceTime(long CounterNr, long DebounceTime);

FUNCTION void __stdcall Version();
FUNCTION long __stdcall SearchDevices();
FUNCTION long __stdcall SetCurrentDevice(long lngCardAddress);

#ifdef __cplusplus
}
#endif[/code]

Oops…
I did now see that my problem was in an earlier stage in the “loadlibrary” function.

>> K8055_Connect Channel (0-3): 0 Status:??? Error using ==> loadlibrary at 367 Failed to preprocess the input file. Output from preprocessor is:'cl' is not recognized as an internal or external command, operable program or batch file.Well I guess i get to this problem later on… :stuck_out_tongue:
