In the world of programming, hexadecimal values can be a bit confusing. But don't worry, we're here to help you understand what these values mean and how to use them in your code.
So, let's start with the basics. What are &H1, &H8000, etc.? These values represent numbers in hexadecimal notation. Hexadecimal is a base-16 number system that uses 16 distinct symbols: 0-9 and A-F.
When you see a value like &H1, it means that the value is represented as a single digit in hexadecimal form. In decimal (base-10) form, this value would be equivalent to 1.
On the other hand, &H8000 represents a value of 32768 in decimal form. This value is made up of two hexadecimal digits: 8 and 00.
So, how do you use these values in your code? In Visual Basic (Classic), you can use the GetKeyState function to retrieve the state of a specific virtual key. The return value specifies the status of the specified virtual key, as follows:
To determine if a key is pressed or not, you can use bitwise AND to test for the presence of the key code. For example:
Code: Dim IsShifted As Boolean IsShifted = (GetKeyState(VK_SHIFT) And &H8000)
In this example, VK_SHIFT represents the shift key, and &H8000 is a hexadecimal value that represents 32768 in decimal form.
By using bitwise AND, you can determine if the shift key has been pressed or not. If the result of the AND operation is non-zero, it means that the shift key has been pressed.
So, to summarize: &H1 and &H8000 are hexadecimal values that represent numbers in base-16 notation. To use these values in your code, you can use bitwise AND to test for the presence of a specific virtual key. By understanding how to work with hexadecimal values, you can write more efficient and effective code.
In this article, we've explored what &H1, &H8000, etc. mean in the context of programming. We've also looked at how to use these values in your code using bitwise AND to test for the presence of a specific virtual key.
By understanding hexadecimal notation and how to use it in your code, you can write more efficient and effective code that takes advantage of the capabilities of modern operating systems.
