电子表格的输入和输出往往需要解决的问题。手术费。
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

第一步,打开Adobe_Acrobat_7.0_Pro_KeyGen.exe,将随机产生一个24位的序列号码.复制.
第二步,打开安装程序,点SETUP,在需要输入序列号的时候,将已复制的24位的序列号码,粘贴.
第三步,一路NEXT,选中通过电话激活方式.点NEXT
第四步,在随后产生的28位代码复制到Adobe_Acrobat_7.0_Pro_KeyGen.exe第二行,注意不要带空格
第5步,点Adobe_Acrobat_7.0_Pro_KeyGen.exe 产生激活代码.
第6步,将激活代码填入安装程序 OK
-The first step, open Adobe_Acrobat_7.0_Pro_KeyGen.exe, will generate a random sequence of 24 numbers. Copy. The second step, open the installer, point SETUP, enter the serial number required at the time, will have to copy the serial number 24 and paste. The third step, all the way NEXT, select activation by phone. NEXT-point fourth step, resulting in the following 28 code Adobe_Acrobat_7.0_Pro_KeyGen.exe copied to the second line, not to bring attention to step 5 spaces, points have to activate code Adobe_Acrobat_7.0_Pro_KeyGen.exe. Step 6, activation code will fill in the installation process OK
