The Win32 API, or software Programming Interface, is of substantial use in extending the facility of visible easy. The Win32 API is the gathering of features and subroutines that gives programmatic entry to the gains of the working method. It permits visible easy programmers a ways larger entry to the interior workings of the home windows working process with no need to endure throughout the steep studying curve linked to visible C++ sort home windows programming. The booklet is designed for clients with an intermediate-level (or larger) wisdom of visible uncomplicated model four or later and a wish to stretch VB into the area of home windows method programming. clients wouldn't have any historical past in visible C++, nor do they want any prior event programming the Win32 API. This ebook teaches clients find out how to do really basic projects, equivalent to including tab stops to an inventory field and amassing process info (i.e., which model of home windows is working on a method and the variety of buttons at the user's mouse). It additionally teaches clients approximately numerous complex programming concepts comparable to synchronizing VB functions to allow them to paintings in cooperation with one another and the way to extract info from controls that belong to a different software. Win32 API Programming with visible easy additionally spends a great deal of time describing the fundamental operations of the home windows NT and home windows 95/98 working structures. Microsoft's documentation seldom takes into consideration what the reader understands or doesn't be aware of. consequently, a great grounding within the fundamentals of the home windows working platforms can help VB programmers to raised comprehend Microsoft's documentation. This ebook is helping VB programmers do away with the trial and mistake procedure that's frequently linked to calling the Win32 API from visible simple and does so in a pragmatic, basic model that's the hallmark of writer Steve Roman's kind.

Example text

So the whole problem boils down to translating between si(w) and un(w). We can see how to make these translations by noting that the only difference between Table 5-1 and Table 5-3 is the negative sign in the first column. Accordingly, there are two cases to consider. The first case is when the number si(w) is nonnegative or, equivalently, the number un(w) is in the lower half of the unsigned range (0 to 32767). ) In this case, the sign bit of w is 0. Hence, as we have seen: un(w) = si(w) Thus, in this case, we can use an ordinary VB integer to pass the number, and, in the other direction, the return value in a VB integer is the actual number (no changes are necessary).

A Long variable is located at a memory address that is a multiple of 4. A Double variable is located at a memory address that is a multiple of 8. A pointer variable, which includes the VB string type BSTR, is located at a memory address that is a multiple of 4. A Unicode character is located at a memory address that is a multiple of 2. In particular, this applies to the characters in a fixed-length string. In addition, the entire structure is aligned on a memory address that is divisible by 4, but this is not relevant to the issue at hand.

Numbers are neither signed nor unsigned. ) Thus, the commonly used term signed integer is highly misleading. It should be read as signed representation of the integer. Nevertheless, this terminology is so common and so convenient that we will use it as well. When we declare an integer variable in Visual Basic and give it a value, as in: Dim i As Integer i = 5 VB represents the integer using the two's complement signed representation. In this, we have no choice. Put another way when VB interprets a binary word as an integer, it does so using the two's complement binary representation of that word.
