use libs under qt4

Hi,
You think:

FUNCTION  CloseDevice();

FUNCTION  CloseDevice();

To copy to clipboard, switch view to plain text mode 

instead of:

FUNCTION __stdcall CloseDevice();

FUNCTION __stdcall CloseDevice();

To copy to clipboard, switch view to plain text mode 

It not works

But __stdcall is not supported by mingw i think, because if i edit the header file to:

#ifdef __cplusplus
extern "C" {
#endif
 
#define FUNCTION __declspec(dllimport)
 
FUNCTION long __stdcall OpenDevice(long CardAddress);
 
 
#ifdef __cplusplus
}
#endif

#ifdef __cplusplus
extern "C" {
#endif

#define FUNCTION __declspec(dllimport)

FUNCTION long __stdcall OpenDevice(long CardAddress);


#ifdef __cplusplus
}
#endif

To copy to clipboard, switch view to plain text mode 

I can use this function "OpenDevice" without problem.

What should i do?

have nobody a idea how to use my header file? I have there a problem with stdcall i think

FUNCTION __stdcall CloseDevice();
FUNCTION __stdcall ReadAllAnalog(long *Data1, long *Data2);
FUNCTION __stdcall OutputAnalogChannel(long Channel, long Data);
FUNCTION __stdcall OutputAllAnalog(long Data1, long Data2);
FUNCTION __stdcall ClearAnalogChannel(long Channel); 
FUNCTION __stdcall ClearAllAnalog();
FUNCTION __stdcall SetAnalogChannel(long Channel); 
FUNCTION __stdcall SetAllAnalog();
FUNCTION __stdcall WriteAllDigital(long Data);
FUNCTION __stdcall ClearDigitalChannel(long Channel);
FUNCTION __stdcall ClearAllDigital();
FUNCTION __stdcall SetDigitalChannel(long Channel);
FUNCTION __stdcall SetAllDigital();
FUNCTION __stdcall ResetCounter(long CounterNr);
FUNCTION __stdcall SetCounterDebounceTime(long CounterNr, long DebounceTime;

FUNCTION __stdcall CloseDevice();
FUNCTION __stdcall ReadAllAnalog(long *Data1, long *Data2);
FUNCTION __stdcall OutputAnalogChannel(long Channel, long Data);
FUNCTION __stdcall OutputAllAnalog(long Data1, long Data2);
FUNCTION __stdcall ClearAnalogChannel(long Channel); 
FUNCTION __stdcall ClearAllAnalog();
FUNCTION __stdcall SetAnalogChannel(long Channel); 
FUNCTION __stdcall SetAllAnalog();
FUNCTION __stdcall WriteAllDigital(long Data);
FUNCTION __stdcall ClearDigitalChannel(long Channel);
FUNCTION __stdcall ClearAllDigital();
FUNCTION __stdcall SetDigitalChannel(long Channel);
FUNCTION __stdcall SetAllDigital();
FUNCTION __stdcall ResetCounter(long CounterNr);
FUNCTION __stdcall SetCounterDebounceTime(long CounterNr, long DebounceTime;

To copy to clipboard, switch view to plain text mode 

All of those functions are missing the return value type. Did you try to add "void" between "FUNCTION" and "__stdcall"?

Hi Jacek!!

Thank you very much it works..How did you find that out?

[jacek]

How did you find that out?

You wrote that "FUNCTION long __stdcall OpenDevice(long CardAddress);" works, so I focused on the differences between this and other declarations.
