How to uses callback function for C++

 

// This is a callback function sample without parameter.
void callbackProc1()
{
    printf("this is a call back 1..\r\n");
}

 

// This is a callback function sample with 2 parameters
bool callbackProc2(int nSize, char* pszName) {
    printf("this is a call back 2..\r\nSize is:%d  pszName is:%s \r\n", nSize, pszName);
    return true;
}

 

// This function invoke callback function as a parameter to it
void test1(void(*p)(void))
{
    p();
}

// This function invoke a callback function with 2 parameters
void test2(bool(*p)(int, char*), int param1, char* param2)
{
    if(p(param1, param2))
    {
        printf("the callback func return TRUE.......\r\n");
    }
}

void main()
{
    // this is a sample to demonstrate how to invoke a callback function without parameter
    // the callback function name is a memory address reference to callback function.
    test1(callbackProc1);
   
    // this is a sample shows how to invoke a callback functions with two parameters
    test2(callbackProc2, 999, "johnrock");
}

How to dynamic manage upload files name in web server

This topic is help to understand how to manage file name uses SQL Server and dynamic specific the client upload file name store in the server file system.

the purpose is save the file to the server file system without having the file name replicated problems. if client download the files from the server, the server can specify the file name depend which the real file name store in the server file system and a popup dialog on user browser  with a file name specify from SQL server but not the physical file name store in the server file system.

 

 

Over write MIME protocol

When Internet Explorer receives the header, it raises a File Download dialog box whose file name box is automatically populated with the file name that is specified in the header.

 

For ASP .NET

Response.AddHeader("content-disposition","attachment; filename=fname.ext");

 

For JSP

response.setHeader( "Content-Disposition", "attachment; filename=" + downloadFileName );

 

Note:

1. You may have to specify the Content Type resp.setContentType( "application/x-download" );
2. Another Content-Type can instate of the content-disposition but it bahaves is differently
   resp.setHeader( "Content-Type", "attachment; filename=" + downloadFileName );

References:
    For more information about content-disposition, see Request for Comments (RFC) 1806
    http://support.microsoft.com/kb/260519

JSP Example
<%@ page  language="java" contentType="text/html"%>
<%@ page import="java.io.*, java.util.*, javax.servlet.*"%>
<%
    if (request.getParameter("filename").equals("") == false)
    {
        String path = request.getParameter("path");
        String filename = request.getParameter("filename");
        response.setContentType("application/octet-stream");
        response.setHeader("Content-Disposition", "attachment; filename=" + request.getParameter("filename"));
        int iRead;
        FileInputStream stream = null;
        try
        {
            File f = new File(path + filename);
            stream = new FileInputStream(f);
            int ilength = 0;
            while ((iRead = stream.read()) != -1)
            {
                out.write(iRead);
            }
            out.flush();
        }
        finally
        {
            if (stream != null)
            {
                stream.close();

How to Load ResourceBundle

Well-formed URLWindows:
file:///d:/props/errmsg.properties
MacOS:
file:///props/errmsg.properties
Linux:
file:///props/errmsg.properties

 

Load Resource from different location

// Load resource from specific file object

File f = new File("d:\\\\props\\res.jar");
URL url = f.toURI().toURL();
URL[] urls = new URL[]{url};

ResourceBundle lang = ResourceBundle.getBundle("tw.com.mycomp.res.properties", new Locale("en", "US"), new URLClassLoader(urls));

 

// Load resource from specific URL

URL[] urls = new URL[]{ new URL("file:///d:/props/errmsg.properties") };
ResourceBundle lang = ResourceBundle.getBundle("tw.com.mycomp.res.properties", new Locale("en","US"), new URLClassLoader(urls));
