hello,I use VC++ compile a DLL,and i want to call DLL Function in LABVIEW program.But there is a dll function
when i call it in labview.There is error.The prototype of Dll Function that make error is "USHORT DLLFUN __stdcall IBWRT(unsigned short dev_address,const char *pstrWrite)",The second paramenter is a char pointer,
and the paramenter pass a command which content is
"MEASURE:CURRENT:DC? 1A,0.001MA".
When i use VC++ to call this function,i program followed:
CString m_wrt;
int ReturnW;
m_wrt="MEASURE:CURRENT:DC? 1A,0.001MA";
char buffer[40];
strcpy(buffer,m_wrt);
ReturnW=IBWRT(4,buffer);
and this call is correct.
But when i use labview to call this function.there is
error.So, who can
help me,to tell me how to call this
function.Thanks.
