网上好象这个例子还没有样,如果你用VC做一个人事部管理系统,不可能没有人员照片吧!能找到的例子中都是用BMP,不敢用!
这个例子用到了VC6.0和access2002(officeXP),涉及到ADO的用法,文件对话框的使用,一个CPicture类和一个buffer缓冲区。
一、我的ADO用法整理
1. stdafx.h头文件中加入:
#import "c:\program files\common files\system\ado\msado15.dll" no_namespace rename("EOF","adoEOF")
2. 应用程序初始化中加入:
AfxOleInit();<br>HRESULT hr;<br>try<br>{<br> hr = m_pConnection.CreateInstance("ADODB.Connection");///创建Connection对象<br> if(SUCCEEDED(hr))<br> {<br> hr = m_pConnection->Open("Provider=Microsoft.Jet.OLEDB.4.0;Data Source=wy.mdb","","",adModeUnknown);///连接数据库<br> ///上面一句中连接字串中的Provider是针对ACCESS2000环境的,对于ACCESS97,需要改为:Provider=Microsoft.Jet.OLEDB.3.51;<br> }<br>}<br>catch(_com_error e)///捕捉异常<br>{<br> CString errormessage;<br> errormessage.Format("打开 wy.mdb 数据库失败!\r\n错误信息:%s",e.ErrorMessage());<br> AfxMessageBox(errormessage);///显示错误信息<br>}
3. 应用程序EXIT中加入:
if (m_pConnection->State)<br> m_pConnection->Close();
4. 应用程序中加入:
_ConnectionPtr m_pConnection;
5. 对话框类中加入:
_RecordsetPtr m_pRecordset;
6. 注意使用:

The advantage of multithreading is that it can improve performance and resource utilization, especially for processing large amounts of data or performing time-consuming operations. It allows multiple tasks to be performed simultaneously, improving efficiency. However, too many threads can lead to performance degradation, so you need to carefully select the number of threads based on the number of CPU cores and task characteristics. In addition, multi-threaded programming involves challenges such as deadlock and race conditions, which need to be solved using synchronization mechanisms, and requires solid knowledge of concurrent programming, weighing the pros and cons and using them with caution.

SQL IF statements are used to conditionally execute SQL statements, with the syntax as: IF (condition) THEN {statement} ELSE {statement} END IF;. The condition can be any valid SQL expression, and if the condition is true, execute the THEN clause; if the condition is false, execute the ELSE clause. IF statements can be nested, allowing for more complex conditional checks.

The main reasons why you cannot log in to MySQL as root are permission problems, configuration file errors, password inconsistent, socket file problems, or firewall interception. The solution includes: check whether the bind-address parameter in the configuration file is configured correctly. Check whether the root user permissions have been modified or deleted and reset. Verify that the password is accurate, including case and special characters. Check socket file permission settings and paths. Check that the firewall blocks connections to the MySQL server.

This article will explain how to improve website performance by analyzing Apache logs under the Debian system. 1. Log Analysis Basics Apache log records the detailed information of all HTTP requests, including IP address, timestamp, request URL, HTTP method and response code. In Debian systems, these logs are usually located in the /var/log/apache2/access.log and /var/log/apache2/error.log directories. Understanding the log structure is the first step in effective analysis. 2. Log analysis tool You can use a variety of tools to analyze Apache logs: Command line tools: grep, awk, sed and other command line tools.

Question: Can MySQL run on macOS? Answer: Yes. Specific instructions: It can be installed through the official MySQL installer. You can use Homebrew to install, providing command-line-driven installation methods and dependency management. Create databases and tables using the MySQL command line client. Optimize query performance and understand indexing, query cache and database standardization. Avoid conflicting version issues and use a single installation method. Ensure secure configuration, use strong passwords and access controls.
