C#迁移之callXBFLibrary - 3(调用COM)

    首先注册COM，

regsvr32 d:\tdtc_atl\xbfInfo.dll

     然后“Add Reference”

COM选项卡

添加完成时

        最后，添加事件。

        1. 写xbf文件

            1）读Ini文件配置

            Boolean flagMSSQL = false;
            Boolean flagSecu = false;
            string sectionName = ini.readIniFileVal("config", "type");
            string strSrv = ini.readIniFileVal(sectionName, "Server");
            if (!Equals(strSrv, ""))
                flagMSSQL = true;
            if (flagMSSQL)
            {
                strConn = "Provider=SQLOLEDB.1;"
                    + "Password=" + ini.readIniFileVal(sectionName, "Pwd") + ";"
                    + "Persist Security Info=True;"
                    + "User ID=" + ini.readIniFileVal(sectionName, "User") + ";"
                    + "Initial Catalog=" + ini.readIniFileVal(sectionName, "DB") + ";"
                    + "Data Source=" + ini.readIniFileVal(sectionName, "Server");

            }
            else // MS Access
            {
                string strPWD = ini.readIniFileVal(sectionName, "Pwd");
                if (!Equals(strPWD, ""))
                    flagSecu = true;
                if (flagSecu)
                {
                    strConn = "Provider=Microsoft.Jet.OLEDB.4.0;"
                        + "Data Source=" + ini.readIniFileVal(sectionName, "DB") + ";"
                        + "Persist Security Info=False;"
                        + "Jet OLEDB:Database Password=" + ini.readIniFileVal(sectionName, "Pwd");
                }
                else
                {
                    strConn = "Provider=Microsoft.Jet.OLEDB.4.0;"
                        + "Data Source=" + ini.readIniFileVal(sectionName, "DB") + ";"
                        + "Persist Security Info=True";
                }
            }

            2）调用COM接口

            xbfLibsLib.genXBFileClass xbf = new genXBFileClass();
            xbf.WriteXBFile(strConn);

       2. 读xbf文件

            genXBFileClass xbf = new genXBFileClass();
            string filePath = currDir + "/" + tb_fileName.Text;
            string strRet = xbf.ReadXBFile(filePath);
            MessageBox.Show(strRet);
