在VS2005下用C#写了一个简单的读取Access数据库的程序,打包,安装,32位机上能正常运行,64位机上始终出现“Microsoft.Jet.OLEDB.4.0provider没有在本地机器上注册”和“Microsoft.ACE.OLEDB.12.0provider没有在本地机器上注册”错误,导致程序不能运行。下
在VS2005下用C#写了一个简单的读取Access数据库的程序,打包,安装,32位机上能正常运行,64位机上始终出现“Microsoft.Jet.OLEDB.4.0provider没有在本地机器上注册”和“Microsoft.ACE.OLEDB.12.0provider没有在本地机器上注册”错误,导致程序不能运行。下面是我的解决步骤:
1 项目属性——生成——目标平台,选择x86,运行程序使其生效。如图:
2 打包时“系统必备”,必备组件选项处选择前两项,安装位置处选择第二项,如图:
3 开始生成安装包,生成完毕,安装包内文件有:两个文件夹和两个文件,如图:
4 更改64位机的IIS属性,如图:
5 将安装包拷贝到64位机上,运行setup.exe进行安装
6 安装完毕运行程序,程序正常运行,未出现异常。
至于出现dll未注册等异常的原因,大家可以参考网址:

Optimizing MySQLBLOB requests can be done through the following strategies: 1. Reduce the frequency of BLOB query, use independent requests or delay loading; 2. Select the appropriate BLOB type (such as TINYBLOB); 3. Separate the BLOB data into separate tables; 4. Compress the BLOB data at the application layer; 5. Index the BLOB metadata. These methods can effectively improve performance by combining monitoring, caching and data sharding in actual applications.

Mastering the method of adding MySQL users is crucial for database administrators and developers because it ensures the security and access control of the database. 1) Create a new user using the CREATEUSER command, 2) Assign permissions through the GRANT command, 3) Use FLUSHPRIVILEGES to ensure permissions take effect, 4) Regularly audit and clean user accounts to maintain performance and security.

Best practices for handling string data types and indexes in MySQL include: 1) Selecting the appropriate string type, such as CHAR for fixed length, VARCHAR for variable length, and TEXT for large text; 2) Be cautious in indexing, avoid over-indexing, and create indexes for common queries; 3) Use prefix indexes and full-text indexes to optimize long string searches; 4) Regularly monitor and optimize indexes to keep indexes small and efficient. Through these methods, we can balance read and write performance and improve database efficiency.
