尚未调用CoInitialize是什么作用，查了帮助，好像没有呐！

打×××这里的错误：

// Unit Methods
void Initialise(String DatabaseName)
{
assert(ADOConn == NULL);
××××ADOConn = new TADOConnection(NULL);××××××××××
ADOConn->ConnectionString = "Provider=SQLOLEDB.1;Integrated Security=SSPI;Persist Security Info=False;Initial Catalog=" + DatabaseName;
ADOConn->KeepConnection = True;
ADOConn->Open();
IDAllocator = new TIDAllocator(DatabaseName);
}

[Friecin]

TADOConnection *ADOConn = new TADOConnection(NULL);


如果你在.h中，声明了 TADOConnection *ADOConn，并声明你的函数 void Initialise(String DatabaseName)，假设这段代码是在 DataModal中的话，则：

在CPP中的定位为：

void TDataMod::Initialise(String DatabaseName)
{
...
}

[Friecin]

还有，关于CoInitialize

API中的
CoInitialize(NULL);
UnCoInitialize(); 必须成对出现；
DLL也有退出的出口：

int WINAPI DllEntryPoint(HINSTANCE hinst, unsigned long reason, void* lpReserved)
{
if (reason==DLL_PROCESS_ATTACH) // DLL入口
CoInitialize(NULL);
else
if (reason==DLL_PROCESS_DETACH)
UnCoInitialize(); // DLL结束

return 1;
}

我没用到DLL,TADOConnection *ADOConn是在我的DataManagementADO.cpp声明的，我的TPDObject对象（在我的ProblemDomain单元里）调用了
//Unit methods
static void Initialization()
{
::Initialise("Northwind");
GlobalOrdersDM = new TOrdersDM();
GlobalOrdersDM->Initialise();
}
是我的Initialization函数（#pragma startup Initialization 32），其调用了DataManagementADO单元的
// Unit Methods
void Initialise(String DatabaseName)
{
assert(ADOConn == NULL);
ADOConn = new TADOConnection(NULL);
ADOConn->ConnectionString = "Provider=SQLOLEDB.1;Integrated Security=SSPI;Persist Security Info=False;Initial Catalog=" + DatabaseName;
ADOConn->KeepConnection = True;
ADOConn->Open();
IDAllocator = new TIDAllocator(DatabaseName);
}
然后就报这个错误了，不知道CoInitialize应该实现，哪里的机制？
