As a programmer, it's essential to understand the basics of hexadecimal numbers and how they're used in coding. In this article, we'll delve into what &H1, &H8000, and other similar codes mean, and provide you with examples of how to use them effectively.

What are &H1, &H8000, etc.?

&H1, &H8000, and other hexadecimal codes are used in programming to represent specific values or flags. These codes are written in a format that starts with the "&H" symbol, followed by one or more digits. In this case, &H1 represents the decimal value 1, while &H8000 represents the decimal value 32768.

How do you use &H1, &H8000, etc. in programming?

To use these codes in your programming, you'll need to understand how they're used in different contexts. For example, if you want to check whether a specific key is pressed on the keyboard, you can use the GetKeyState function and perform a bitwise AND operation with &H8000. This will tell you whether the key is down or not.

Example: Checking for ALT Key Press

Let's say you want to create a function that copies text from an input box to the clipboard when the user presses the ALT and X keys simultaneously. To do this, you can use the following code:

Public Const VK_ALT = &H12
Public Type KBDLLHOOKSTRUCT
  vkCode As Long ' virtual keycode
  scanCode As Long ' hardware scancode
  flags As Long
  time As Long
  dwExtraInfo As Long
End Type

Dim IsALT As Boolean
IsALT = (GetKeyState(VK_ALT) And &H8000) 'Ctrl Key
tempVKCodeHolder = correctedInputValues(CInt(Trim(HookStruct.vkCode))) 'Takes the interpreted keyboard input value and translates it to its proper ascii value.
If ((IsAlt = True) And (tempVKCodeHolder = 88)) Then
  Clipboard.Clear
  Clipboard.SetText(strUserInput)
  Exit Function
End If

Conclusion

In conclusion, &H1, &H8000, and other hexadecimal codes are essential tools for programmers to understand. By grasping the basics of these codes and how they're used in programming, you'll be able to create more effective and efficient code. Remember to always refer to the MSDN page for the GetKeyState function when using these codes, as it provides a wealth of information on their usage.

Recommendations

If you're new to programming or need a refresher on hexadecimal numbers, we recommend starting with the basics. Practice using &H1, &H8000, and other similar codes in your code to get a feel for how they work. Don't be afraid to ask questions or seek help from experienced programmers when needed.
