VCDLL已经创建好。
我建了一个类
大致代码如下
C/C++ code:
typedef class ZHallAPI
{
public:
virtual int GetVersion() = 0;
virtual int Prepare() = 0;
virtual int UnPrepare() = 0;
virtual int Connect(char* szIPAddr, unsigned short usIPPort) = 0;
virtual int DisConnect() = 0;
virtual int ClientLogin(const LPCLIENTLOGIN lpClientLogin, LPCLIENTLOGINRST lpClientLoginRst, char* szErrInfo) = 0;
} HALLAPI, *LPHALLAPI;
LPHALLAPI __stdcall GetHallApi();
LPHALLAPI __stdcall GetHallApi()
{
static ZClientInstance Instance;
return &Instance;
}
int ZClientInstance::MyPrepare()
{
int iRet(0);
if(this->bPrepared)
{
return T_OK;
}
this->lpClientAPI = GetClientAPI();
iRet = this->lpClientAPI->Prepare();
if(Z_OK != iRet)
{
return ERR_TP_CLIENT_ERROR;
}
this->bPrepared = true;
return T_OK;
}
int ZClientInstance::Prepare()
{
int iRet =this->MyPrepare();
if(T_OK != iRet)
{
this->UnPrepare();
}
return iRet;
}
int ZClientInstance::GetVersion()
{
//return this->API_VERSION;
return 123;
}

该dll在vc下调用测试通过，在delphi中测试调用，会报地址异常
如何使新增的sheet在前一个sheet后，excel默认有3个sheet,如我新增一个sheet4,怎样使它是插在sheet3后呢，而不是插在sheet1前？
右键不行吗？
Worksheets.Add 方法
该方法用于新建工作表。
Function Ad ......
function ReadTime(intDevno: Integer; var strGet: Pchar): Integer; stdcall; external 'ast.dll'; //读取日期时
bcb调用delphi 的dll这句在bcb中如何转化。
应该是C/C++ code:
int __stdcall ReadTime(int in ......
