该EXE软件可以免去通过SQL EXPLOR或者数据库查询界面进行查询的麻烦，直接可以打开该EXE文件，因为该EXE是读去BDE中的数据库别名进行连接，所以使用的时候你的保证你的数据库是否通过ODBC连接上。 因为在程序中用到了第三方控件（主要是RAISE系列控件），以及我自己在第三方控件开发的控件，所以打开界面是如果没有安装第三方控件可能报错，不过没关系，我用第三方控件都是处理界面用的，你完全可以用DELPHI自带的标准控间进行替换，从而达到在自己可以编译。-the software can avoid EXPLOR or SQL database query interface for the trouble, can directly open the EXE file, which is read out EXE BDE the alias database linking, the use of the time you ensure that your database through ODBC connection. Because the procedures used by third-party controls (mainly RAISE series of controls), and my own controls in the development of third-party control, so if the open interface is not possible to install third-party control errors, but okay, I used to deal with third-party interface controls are used, you can use Delphi"s own standards for inter-controlled replacement, and thereby achieve it in their own compiler.

在vb中调用excel文件，进行excel的设置和数据的处理。-in vb Calling excel, excel for the setup and data processing.

Excel表格是输入输出经常需要涉及到的。操作Excel表格的方式也多种多样。比如，通过调用Excel程序的COM组件对Excel进行操作。但是，这种方式限制较多，且实现难度比较大。但是，用于访问数据库的组件ADO，是支持多种数据源的，其中就包括Excel文件。我们可以通过ADO组件对Excel文件进行读写访问。当然，在.NET平台上对应ADO数据访问组件的是ADO.NET组件。我编写的这个类就是通过ADO.NET实现了Excel文件的读写。由于时间仓促，功能还不是很完善，会在以后有时间的时候进行版本升级。也请各位高手多多批评指正。-Excel spreadsheet input and output is often of the need to address. Operation Excel variety of ways. For example, by calling the Excel COM procedures for the operation of Excel. However, this approach is more limited and more difficult to achieve. However, for access to the database components ADO, is to support multiple data sources, including Excel file. We can ADO components to read and write Excel files visit. Of course,.NET platform counterparts ADO data access components of ADO.NET components. I prepared this category is achieved through ADO.NET read and write Excel files. Because time is so short, the function is still not perfect, will in future have the time for version upgrades. Members also criticized many exp
