Today, my colleague sent me an access file and opened it and jumped out of a form. I want to see some properties of this form. I didn't expect the file to be automatically closed after I pressed the design view button. # % $ *@! # ^ ?, Challenge me!
Open the file again and clickToolsMenu>StartupIn general, the form started when the access file is opened is set here, but there is nothing in the main here. I originally wanted to cancel the form opening here.
Let's take a look at the other one
In Windows XP, autoexec. BAT and config. sys are not used. The two files are empty autoexec. BAT and config. sys is a text file and can be opened directly in notepad. aiuoexec. BAT was used in earlier DOS to execute batch processing commands when the system was started. config. sys was used to set up related environments on earlier dos, which contains some configuration commands. Opening it does not require
management. This space is umb (upper-level memory block). "noems" indicates that the system does not provide any memory expansion function, the emm386 administrator simulates the extended memory as the extended memory. "I = B000-B7FF" indicates that the address is b000 ~ B7ff (For monochrome display Rom ing ROM) memory of 32 KB is released to umb.

Clear information. This file is not required in the Windows XP operating system. However, by default
XP will still process the content in this file at startup, which may cause some malicious programs to crash, such as in autoexec.

? It doesn't matter. If you don't install Win2000, you can also realize the coexistence of multiple ipvs mentioned above. This technique applies to cloning and recovering a C drive with the previous Win9x after Win2000 is installed. However, you need to explain it in a short sentence. Please take a look .)1. Make the first partition C: dos6.22, Win32, and Win95 coexist.I don't need to talk about this. Win9x itself supports coexistence of these three systems. To put it simply, export the system f
the contents of a.txt and B .txt in sequence.
In addition, the computer will look for autoexec every time it starts up. BAT: this batch file allows you to execute commands to be executed every time you start the system, such as setting the path, loading the mouse driver, and accelerating disk smartdrv, can make your computer truly automated.
Special commands

displays the contents of all files with bat and txt extensions under the current directory.
Batch processing sample

First use Notepad to create a test1.bat batch file in C:\, which reads as follows:
@echo off
IF EXIST \autoexec. BAT TYPE \autoexec. BAT
IF not EXIST \autoexec. BAT ECHO \autoexec. BA
command [Command-parameters]
%%variable specifies a single letter replaceable parameter.(set) to specify one or a set of files. You can use wildcard characters.command specifies the commands that are executed for each file.Command-parametersSpecify a parameter or command-line switch for a specific command.
For example, there is one row in a batch file:For%%c in (*.bat *.txt) do type%%c
The command line displays the contents of all files with bat and txt extensions under the current directory
processing capability depends on the commands you use.
Third, each written batch processing file is equivalent to a DoS external command. You can put the directory in your dos search path) so that it can run in any location. A good habit is to create a bat or batch directory (for example, c: \ batch) on the hard disk, and then put all the batch files you have compiled into this directory, in this way, you only need to set C: \ batch in the path, and you can run all your batch processing program
