TADOConnection *ADOConn;
TADOQuery *Qry_Dept;
TDataSource *DS_Dept;
TStringField *Qry_DeptdeptNo;
TStringField *Qry_DeptdeptName;
TStringField *Qry_DeptdeptState;
TStringField *Qry_DeptdeptMemo;
void __fastcall DataModuleCreate(TObject *Sender);
private: // User declarations

public: // User declarations
__fastcall TDM(TComponent* Owner);

};
//---------------------------------------------------------------------------
extern PACKAGE TDM *DM;
//---------------------------------------------------------------------------
#endif

Unit_dm.cpp文件内容 如下 ：
//---------------------------------------------------------------------------

#include

#include "Unit_DM.h"
//---------------------------------------------------------------------------
#pragma package(smart_init)
#pragma resource "*.dfm"

{
}
//---------------------------------------------------------------------------
void __fastcall TDM::DataModuleCreate(TObject *Sender)
{
String connStr="",PasswordStr="",UserStr="",DatabaseStr="",ServerStr=""; //
TIniFile *ini;
try
{
// connStr= " Provider=SQLOLEDB.1;Password=wzr;Persist Security Info=

ADOConn->Close();
ini=new TIniFile(".//config.ini");
PasswordStr=ini->ReadString("connection","Password","") ;
// ShowMessage(PasswordStr);
UserStr=ini->ReadString("connection","User","");
// ShowMessage(UserStr);
DatabaseStr=ini->ReadString("connection","Database","");
ServerStr=ini->ReadString("connection","Server","");

connStr="Provider=SQLOLEDB.1;Password="+PasswordStr+";Persist Security Info=True;User ID=";
connStr=connStr+UserStr+";Initial Catalog="+DatabaseStr+";Data Source="+ServerStr ;

ADOConn->ConnectionString="";
ADOConn->ConnectionString=connStr;
ADOConn->Open();
ADOConn->Connected=true;
}
catch(...)
{
Application->MessageBoxA("数据库连接失败，请检查数据库服务或网络连接。","错误信息",0+64);
