Why is programming needed?
You want to write an essay on biology. Most likely, you will write it on your computer in some text editor. Where did the text editor come from? Of course, it was written by programmers. You will search for information on the Internet using a browser that was also written by programmers. After you write your essay, you will want to relax and play computer game, which was again written by programmers. In general, working on a computer is impossible without using programs that programmers write. This means that if there were no programming, there would be no programs, and the computer would be a pile of expensive hardware, because it is impossible to do something using a computer without programs.
Stages of problem solving.
Basic Concepts
Programming - writing programs.
Program - an algorithm written in a programming language that a computer can understand.
Algorithm – a clear sequence of actions aimed at achieving the goal.
In object-oriented programming the concept of an object was introduced, calculation mechanisms were implemented, allowing:
Describe the structure of an object
Describe actions with objects
Use special object inheritance rules (Inheritance means creating new objects from existing ones)
Set the degree of protection of object components
Theory
First acquaintance
Microsoft Small Basic - a programming language developed by . Designed for beginner developers who want to learn the basics of creating programs.
Main advantages:
A very simple development environment - a text editor with a multifunctional tooltip and only a few buttons for editing text and launching programs.
Simple language with only 20 keywords
Contextual documentation for all language elements built into the development environment
The ability to extend Small Basic components to include additional functionality. (For example, the delivery already includes capabilities for working with services)
A special advantage of BASIC is the ability to work in interpretation mode, which greatly simplifies the process of debugging programs: the execution of almost every command can be checked immediately after writing.
Inference operator
WriteLine("Hello!")Displays the string (text or number )
Hello!
To get the result - displaying the text “Hello!” to the screen - you need to write a program:
TextWindow.WriteLine("Hello!")
The program is entered into the windowSmallBasicand starts with a buttonLaunch or key F 5
The result of the program is the text output: "Hello!" VText box programs.
The line means “Press any key to continue...”
TextWindow is a “text window” object in which text can be displayed.
The object has properties And methods.
Object method -what an object can do, i.e. itoperations (operators )
Parameter The operation is enclosed in the WriteLine parentheses()
Also an object text box has properties (these are the characteristics of the object) , For example
BackgroundColor property – sets the background color for the text,ForegroundColor- text color
Colors:
redyellow

Variable
Variables are often used to create programs.
The variable hasName - Latin letter (a)
A variable can be assigned a value, such as a numeric value
a= 5, where the sign " = " - This assignment operator
String valuea = a + 5
Take the value of variable a
Add 5 to it
Put a new value in variable a, erasing the previous one from it
There are two types of variable: number And line

Hello everyone, in this article I want to show you useful codes for small programs. Which you can use to write your own more serious programs, or you were looking for exactly these functions that are described here.
All codes were used in the programming environment Microsoft Visual Basic v6.0.
Exit with confirmation
The first kind of program, or function, is an exit with a message confirming the exit. In general, open the environment Visual programming Basic, create a standard project, then place one button on the form, click on the button and a code editing window will open, and you need to insert the following code there:
Beep Dim message As String Dim buttonsandicons As Integer Dim title As String Dim response As String message = "Do you want to go out?" title = "Exit" buttonasicons = vbYesNo + vbQuestion response = MsgBox(message, buttonasicons, title) If response = vbYes Then End End If !}
Password to start the program
Dim Password, Pword PassWord = "12345" Pword = InputBox("Enter password") If Pword<>PassWord Then MsgBox "Password is not correct" End End If
Where, 12345 is the password to start the program. But this code can be used wherever you want.
Message output
If you just want to display a message for something, then paste this:
Beep Dim message As String Dim buttonsandicons As Integer Dim title As String message = "Message" title = "Message" buttonasicons = vbOKOnly + vbexciamation MsgBox message, buttonsandicons, title !}
Drawing on the form
Private Sub Form_MouseDown(Button As Integer, Shift As Integer, X As Single, Y As Single) Form1.CurrentX = X Form1.CurrentY = Y End Sub Private Sub Form_MouseMove(Button As Integer, Shift As Integer, X As Single, Y As Single) If Button = 1 Then Line (Form1.CurrentX, Form1.CurrentY)-(X, Y), QBColor(0) End If End Sub
You can change the color using the QBColor(0) parameter, i.e. Instead of 0, put another number.
Restarting the computer
To reboot your computer: place the button and paste the following code:
Dim strComputer As String strComputer = "." Set objWMIService = GetObject("winmgmts:" & "(impersonationLevel=impersonate, (Shutdown))!\\" _ & strComputer & "\root\cimv2") Set colOperatingSystems = objWMIService.ExecQuery("Select * from Win32_OperatingSystem") For Each ObjOperatingSystem In colOperatingSystems ObjOperatingSystem.Reboot " To reboot NextLaunching a program in a single copy
The following example will help you make the program run only once, i.e. if it is restarted, it will display a corresponding message. Insert the following into the form code:
Private Sub Form_Load() If App.PrevInstance = True Then MsgBox "The project has already started!" End End If
Turning off the computer
To turn off your computer you can use the following code:
Dim strComputer As String strComputer = "." Set objWMIService = GetObject("winmgmts:" & "(impersonationLevel=impersonate,(Shutdown))!\\" _ & strComputer & "\root\cimv2") Set colOperatingSystems = objWMIService.ExecQuery("Select * from Win32_OperatingSystem") For Each ObjOperatingSystem In colOperatingSystems ObjOperatingSystem.ShutDown "To shut down Next
Ending any process
To terminate the process you can use the following code:
Shell "Cmd /x/c taskkill /f /im ICQlite.exe", vbvhite
Where, instead of ICQlite.exe there can be any process.
How long does the computer last?
Below is an example of how you can determine the computer's operating time. This method is based on the use of the kernel32 library, so at the very beginning of the form code, connect this DLL.
Private Declare Function GetTickCount Lib "kernel32" () As Long "And in the button code: Dim a_hour, a_minute, a_second a = Format(GetTickCount() / 1000, "0") "total seconds a_days = Int(a / 86400) a = a - a_days * 86400 a_hour = Int(a / 3600) a = a - a_hour * 3600 a_minute = Int(a / 60) a_second = a - a_minute * 60 MsgBox "Your computer is running " & Str(a_days) & " days " & Str(a_hour) _ & " hours " & Str(a_minute) & " minutes" & Str(a_second) & " seconds"
We have reviewed simple functions, which can be used almost anywhere. Now let's look at more serious examples, and they can greatly help you write your large projects.
Examples of working with folders
Delete directory
Private Declare Function RemoveDirectory& Lib _ "kernel32" Alias "RemoveDirectoryA" (ByVal lpPathName As String) "Removing directory (empty!) PathName$ = "D:\t" code& = RemoveDirectory(PathName) If code& = 0 Then "Error removing directory Else "Directory deleted End IfCreate directory
Sub MakeDir(dirname As String) Dim i As Long, path As String Do i = InStr(i + 1, dirname & "\", "\") path = Left$(dirname, i - 1) If Right$(path , 1)<>":" And Dir$(path, vbDirectory) = "" Then MkDir path End If Loop Until i >= Len(dirname) End Sub Private Sub Command1_Click() Call MakeDir("C:\Soft\1\2\3\ ") End SubList all folders with sub folders
We add 2 text fields and a button to the form, the name of the first text field is StartText, the name of the second text field is OutText. Multiline property = true, button name = CmdStart
Static running As Boolean Dim AllDirs As New Collection Dim next_dir As Integer Dim dir_name As String Dim sub_dir As String Dim i As Integer Dim txt As String If running Then running = False CmdStart.Enabled = False CmdStart.Caption = "Stopping" Else running = True MousePointer = vbHourglass CmdStart.Caption = "Stop" OutText.Text = "" DoEvents next_dir = 1 AllDirs.Add StartText.Text Do While next_dir<= AllDirs.Count dir_name = AllDirs(next_dir) next_dir = next_dir + 1 sub_dir = Dir$(dir_name & "\*", vbDirectory) Do While sub_dir <>"" If UCase$(sub_dir)<>"PAGEFILE.SYS" And sub_dir<>"." And sub_dir<>".." Then sub_dir = dir_name & "\" & sub_dir On Error Resume Next If GetAttr(sub_dir) And vbDirectory Then AllDirs.Add sub_dir End If sub_dir = Dir$(, vbDirectory) Loop DoEvents If Not running Then Exit Do Loop txt = "" For i = 1 To AllDirs.Count txt = txt & AllDirs(i) & vbCrLf Next i OutText.Text = txt MousePointer = vbDefault unning = False End If
Now we launch the program, write in the StartText text field: C:\windows, and click on the button.

Then dblSize = dblSize + SizeOf(EndSlash(DirPath) & sName) End If Else dblSize = dblSize + fdata.nFileSizeHigh * 65536 + fdata.nFileSizeLow End If DoEvents Loop While FindNextFile(hFind, fdata)<>0 hFind = FindClose(hFind) End If Else On Error Resume Next dblSize = FileLen(DirPath) End If SizeOf = dblSize End Function Private Function EndSlash(ByVal PathIn As String) As String If Right$(PathIn, 1) = "\" Then EndSlash = PathIn Else EndSlash = PathIn & "\" End If End Function Private Sub Form_Load() "Replace "D:\soft" with the directory whose size you want to know MsgBox SizeOf("D:\soft") / 1000000 End SubExamples of working with files
Copy
Let's say we have a file named 1.txt in the C:\1\ folder, and we need to copy it to C:\2\ to do this we write the following code:
Filecopy "C:\1\1.txt","C:\2\1.txt"
Note! If directory 2 already contains a file named 1.txt, it will be replaced with 1.txt from directory 1.
Private Declare Function CopyFile Lib _ "kernel32.dll" Alias "CopyFileA" _ (ByVal lpExistingFileName As String, ByVal lpNewFileName As String, ByVal bFailIfExists As Long) As Long Private Sub Command1_Click() " Copy file C:\1.txt to D :\1.txt. Dim retval As Long " return value "Copy the file retval = CopyFile("C:\1.txt", "D:\1.txt", 1) If retval = 0 Then "If error MsgBox " I can't copy" Else "If everything is fine MsgBox "File copied." End If End Sub
Removal
For example, we want to delete file 1.txt from the root of the C:\ drive
Kill("C:\1.txt")
API method
Private Declare Function DeleteFile Lib _ "kernel32.dll" Alias "DeleteFileA" (ByVal lpFileName As String) As Long Private Sub Command1_Click() "Delete file C:\Samples\anyfile.txt Dim retval As Long "Return value retval = DeleteFile( "C:\1.txt") If retval = 1 Then MsgBox "The file was successfully deleted." End Sub
Moving
You can, for example, move it like this:
Filecopy "C:\1.txt","C:\2\1.txt" Kill ("C:\1.txt")
But it's better like this (via API):
Private Declare Function MoveFile Lib _ "kernel32.dll" Alias "MoveFileA" _ (ByVal lpExistingFileName As String, ByVal lpNewFileName As String) As Long Private Sub Command1_Click() Dim retval As Long "Return value retval = MoveFile("C:\1 .txt", "C:\2\1.txt") If retval = 1 Then MsgBox "Moved successfully" Else MsgBox "Error" End If End Sub
Renaming
In order to rename the file 1.txt located in C:\ to 2.txt you can use the following code:
Filecopy "C:\1.txt","C:\2.txt" Kill ("C:\1.txt")
API method
Private Declare Function MoveFile Lib _ "kernel32.dll" Alias "MoveFileA" _ (ByVal lpExistingFileName As String, ByVal lpNewFileName As String) As Long Private Sub Command1_Click() Dim retval As Long " return value retval = MoveFile("C:\1 .txt", "C:\2.txt") If retval = 1 Then MsgBox "Success" Else MsgBox "Error" End If End Sub
Determine file size
The file size can be determined in two ways:
If the file can be opened with the OPEN function, then you can use the LOF function
Dim FileFree As Integer Dim FileSize As Long FileFree = FreeFile Open "C:\WIN\GENERAL.TXT" For Input As FileFree FileSize = LOF(FileFree) Close FileFree
Or use the FileLen function
Dim lFileSize As Long FileSize = FileLen("C:\WIN\GENERAL.TXT")
Hide clock programmatically
Add 2 buttons and paste the code:
Option Explicit Private Declare Function FindWindow Lib _ "user32" Alias "FindWindowA" (ByVal lpClassName As String, ByVal lpWindowName As String) As Long Private Declare Function FindWindowEx Lib _ "user32" Alias "FindWindowExA" _ (ByVal hWnd1 As Long, ByVal hWnd2 As Long, ByVal lpsz1 As String, ByVal lpsz2 As String) As Long Private Declare Function ShowWindow Lib _ "user32" (ByVal hwnd As Long, ByVal nCmdShow As Long) As Long Dim hnd As Long Private Sub Command1_Click() ShowWindow hnd, 0 End Sub Private Sub Command2_Click() ShowWindow hnd, 1 End Sub Private Sub Form_Load() hnd = FindWindow("Shell_TrayWnd", vbNullString) hnd = FindWindowEx(hnd, 0, "TrayNotifyWnd", vbNullString) hnd = FindWindowEx(hnd, 0, "TrayClockWClass", vbNullString) Command1.Caption = "Hide clock" Command2.Caption = "Show clock" End Sub
Add tray icon
Add a module and paste the code into it:

Putting a program into startup
In order for the program to load with Windows, like some other programs, you can use the registry:
Add 2 buttons and the following code:
Private Sub Command1_Click() "Registry entry Set Reg = CreateObject("WScript.Shell") Reg.RegWrite "HKLM\Software\Microsoft\Windows\CurrentVersion\Run\Name of your program", _ "Path to your program" End Sub Private Sub Command2_Click() "Delete from the registry Set Reg = CreateObject("WScript.Shell") Reg.RegDelete "HKLM\Software\Microsoft\Windows\CurrentVersion\Run\Name of your program" End Sub
And in order for the program to load along with Windows, even in safe mode, then this code:
First, a more serious method (do it just in case backup copy registry).
Private Sub Command1_Click() Set Reg = CreateObject("WScript.Shell") Reg.RegWrite "HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\WindowsNT\CurrentVersion\Winlogon\Shell", _ "Path to your program" End Sub Private Sub Command2_Click()" This is for recovery Set Reg = CreateObject("WScript.Shell") Reg.RegWrite "HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\WindowsNT\CurrentVersion\Winlogon\Shell", _ "Explorer.exe," End Sub
Well, a simple way.
Private Sub Command1_Click() Set Reg = CreateObject("WScript.Shell") Reg.RegWrite "HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\WindowsNT\CurrentVersion\Winlogon\Userinit", _ "C:\\WINDOWS\\system32\\userinit.exe ,The path to your program" End Sub Private Sub Command2_Click()"To restore Set Reg = CreateObject("WScript.Shell") Reg.RegWrite "HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\WindowsNT\CurrentVersion\Winlogon\Userinit", _ "C: \\WINDOWS\\system32\\userinit.exe," End Sub
Hiding the taskbar
Add 2 buttons and paste the code:
Private Declare Function SetWindowPos Lib "user32" (ByVal hwnd As Long, _ ByVal hWndInsertAfter As Long, ByVal x As Long, ByVal y As Long, _ ByVal cx As Long, ByVal cy As Long, ByVal wFlags As Long) As Long Private Declare Function FindWindow Lib "user32" Alias "FindWindowA" _ (ByVal lpClassName As String, ByVal lpWindowName As String) As Long Const SWP_HIDEWINDOW = &H80 Const SWP_SHOWWINDOW = &H40 "Hide Private Sub Command1_Click() hwnd1 = FindWindow("Shell_traywnd", "") Call SetWindowPos(hwnd1, 0, 0, 0, 0, 0, SWP_HIDEWINDOW) End Sub "Shows Private Sub Command2_Click() hwnd1 = FindWindow("Shell_traywnd", "") Call SetWindowPos(hwnd1, 0, 0, 0, 0, 0, SWP_SHOWWINDOW) End Sub
Unzip RAR archive
In order to unzip the RAR archive, you can use the following code:
WinRarApp = "C:\Program Files\WinRAR\WinRAR.exe x -o+" iPath = "C:\" iArhivName = "File name.rar" adr = WinRarApp & " """ & iPath & iArhivName & """ " "" & iPath & """ " RetVal = Shell(adr, vbHide)
How much RAM is in the computer
Add one button and paste the following code:
Private Declare Sub GlobalMemoryStatus Lib "kernel32" (lpBuffer As TMemoryStatus) Private Type TMemoryStatus dwLength As Long dwMemoryLoad As Long dwTotalPhys As Long dwAvailPhys As Long dwTotalPageFile As Long dwAvailPageFile As Long dwTotalVirtual As Long dwAvailVirtual As Long End Type Dim s As TMemoryStatus Private Sub Command1_Click( ) ms.dwLength = Len(ms) Call GlobalMemoryStatus(ms) MsgBox "Total:" & ms.dwTotalPhys & vbCr & "Free:" _ & ms.dwAvailPhys & vbCr & "Used in %:" & ms.dwMemoryLoad End Sub
Hide desktop icons
This is done as follows. Add 2 buttons and paste the following code:
Private Declare Function ShowWindow& Lib "user32" (ByVal hwnd&, ByVal nCmdShow&) Private Declare Function FindWindow Lib _ "user32" Alias "FindWindowA" (ByVal lpClassName As String, ByVal lpWindowName As String) As Long Const SW_HIDE = 0 Const SW_NORMAL = 1 Private Sub Command1_Click() Dim hHandle As Long hHandle = FindWindow("progman", vbNullString) Call ShowWindow(hHandle, SW_HIDE) End Sub Private Sub Command2_Click() Dim hHandle As Long hHandle = FindWindow("progman", vbNullString) Call ShowWindow(hHandle , SW_NORMAL) End Sub
Using the Command1 button, the icons are hidden, Command2 - they appear.
That's all for me, I hope the above examples will be useful to you, bye!
