extern "C" __dec
lsp
ec(dllexport) int main(char * src,char * dest)
{
char*data = NULL;
strcpy(dest, "ffffffff");
return 0;
//return (char)dest;
}
vb6返回 fffffff
vb.net返回为空
'<DllImport("S3wER.dll", EntryPoint:="main", CallingConvention:=CallingConvention.Cdecl)> Public Shared Function main(ByVal src As String, ByVal dest As String) As Int16
'End Function
调用方法

好像是这个代码有问题
在vb.net 里不能反回数据
extern "C" __declspec(dllexport) int main(char * src,char * dest)
{
char*data = NULL;
strcpy(dest, "ffffffff");
return 0;
}
