    loop

    It's still looping here, how do you turn the rk off.

    Put the last %>

    Then you undo the judgment statement.

    if len(rk("title"))>14 then"title"),14)+" …")

    else "title"))

    end if

    Replace with <%=rk("title"%> to see if this happens, it is estimated that there is a problem with your judgment statement.

    Is this what the original record of the database table is?

    With while... Wend try.

    Or is the database data duplicated?

    Take a look with for. (The premise is that you have at least 4 records in your database.) )sql,conn,1,1

    for i = 1 to 4

    target="_blank">

    if len(rk("title"))>14 then"title"),14)+" …")

    else "title"))

    end if

    See if there are 4 or 8 records.

    If it's 8, it's weird.

    Sometimes things are done as if in a dream.

    Asynchronous ** is to process your own response without waiting for a response after initiating the request, it does not process the entire request, but only processes a small part, and on the web page, it is manifested that the page is not refreshed, but the data is partially updated.

    Synchronization means that you have to wait until you respond to the request before you can do anything else, and when it comes to a web page, the entire page is refreshed and the data is updated.

    Here are two examples:

    Let's start with an example of a synchronous call:

    For example, if your program calls a method, and this method needs to be executed for a long, long time, and the time is uncertain, the traditional method is to "call synchronously", as follows:

    private int func()

    private void a()

    With the above method, which can be called a synchronous call, it is clear that it has a drawback:

    The func method is executed for too long, the program will be blocked, and can not continue to execute other **, the experience given to the user is that the whole program will be stiff, open the task manager will prompt that the program is not responding, the user thinks the program is dead, it will manually end the program, asynchronous call is not the same, after calling the func method, do not have to wait for the func to be executed, you can execute the other**, until the func is executed, the result is returned, If func provides an asynchronous method funcasync(), it can be called like this:

    private void a()

    private void funccompleted(int n)

    Asynchronous needs to be written to support, network transmission libraries generally provide asynchronous methods, such as socket programming, web services, AJAX, WCF, etc., some asynchronous is done by the same thread, and some asynchronous is different threads, so if you want to update the control in the function, it will prompt the error prompt of cross-thread access to the control.

    Changsha is extremely information technology****.

    Does it mean that you want to connect to the database? You can come to me privately.

    It's supposed to be creating data, right? This includes things like names and scores.
