出现调用dll约定错误！怎么解决呀？
Prototype
int OptoPCI_OpenDriver (char szShortPath[260] )
Function parameters
Direction Name Type Meaning
Transfer szShortPath char For Win95, Win98 and WinME path
specification where the VxD driver
is located on the computer
(necessary if it is not in the same
path and not listed in the system
directory)
ReturnExplanation of function parametersFunction return
DRV_ERR_OK, DRV_ERR_NOVDALOGD
C
#include “LibOpto.h"
char szShortPath[260];
int iRet = API__OptoPCI_OpenDriver( szShortPath );
if (iRet == DRV_ERR_NOVDALOGD)
{
printf("Error on opening the driver");
}
Recommendation
Use in the Init section
vc的int对应vb的long
vc的UINT和WORD DWORD还有BOOL和一些指针都对应vb的long
