Window programming

The program uses all the standard controls in Windows programs. In addition, the use of an extensive number of shortcuts and function keys makes it possible to control the system without the use of a mouse, which is convenient for operating the system in the field. 

One free software package worth downloading is WRPLOT View, which is a fully operational wind rose Windows program for your meteorological data. WRPLOT View is the logical replacement for the popular U.S. EPA DOS utility WRPLOT (this second program is also available at the site and is noted below). WRPLOT View s main features are ... 

MS-WINDOWS Program Manager, to call the GETFILE program for copying and converting data files stored on remote computers, to extract FIDs from a 2D spectrum into ID WIN-NMR spectra and to exit the WIN-NMR program. 

Sends the plot as a vector-oriented metafile to the MS-WINDOWS clipboard from where it can be transferred into any other MS-WINDOWS program. The plot area of the output is taken from the currently displayed area in the Spectrum window. Parameter lists and the title cannot be transferred using this method. They can be copied by transferring the output, including the title and lists, first into the Preview window, from where it may be copied to the MS-WINDOWS clipboard using the Copy option in the Edit pull-down menu in the Preview window menu bar. 

When Windows runs out of memory, hard disk space, or both, we say it has run out of system resources. Windows 3.1 has an About window (in the Windows Program Manager screen, select Help > About) that can be used to check the amount of available system resources (see Figure 10.1). For optimal Windows performance, the available system resources should be above 80 percent. If they are below 80 percent you will need to add RAM, disk space, or both. 

The Registry can be viewed and edited with REGEDIT.EXE. When you run this program, it presents the view shown in Figure 10.3. Each folder represents a section or key that contains specific information. It is within these keys that the settings for the Windows programs are kept. 

Has any new software been installed recently New software can mean incompatibility problems with existing problems. This is especially true for Windows programs. A new Windows program can overwrite a required DLL file with a newer version of the same name, which an older program may not find useful. 

As of this writing, DOS 6.22 is the most current MS-DOS version available as a stand-alone operating system. Microsoft has included certain DOS-style command line utilities for use within Windows 95, Windows NT and Windows 2000, but these are actually Windows programs that simply mimic the familiar, old command-prompt environment of DOS. 

Notepad is a very simple Windows program. It has only a single menu bar and the basic elements seen previously in Figure 12.17. Figure 12.18 shows a Microsoft Word window. Both Word and Notepad are used to create and edit documents, but Word is far more configurable and powerful and therefore has many more optional components available within its window. 

We will look at a number of graphical utilities in the next few chapters and, believe it or not, the command prompt is one of them. Although you can t tell from looking at it (see Figure 12.20), the crazy thing about the Windows command prompt is that it is actually a 32-bit Windows program that is intentionally designed to have the look and feel of a DOS command line ... 

Because it is, despite its appearance, a Windows program, the command prompt provides all of the stability and configurability that you would expect from Windows. 

Configuration information is also stored in a special configuration database known as the Registry. This centralized database contains environmental settings for various Windows programs. It also contains what is known as registration information, which details which types of file extensions are associated with which applications. So, when you double-click a file in Windows Explorer, the associated application runs and opens the file you double-clicked. 

The wizard will ask you a series of questions that will help you to configure the printer. The first question it will ask you is Do you print from MS-DOS-based programs The reasoning behind this question is similar to the reason we map drive letters. Most older DOS programs (and to a lesser extent, Windows programs) don t understand the UNO path syntax for access to a shared resource. Instead, they understand a name for a local hardware resource (like LPTl, for the first local parallel port). So, you must point a local printer port name out to the network in a process known as capturing. If you need to capture a printer port, answer Yes ... 

Once the technician has sorted out all the problems, it s time to actually repair whatever went wrong. In the above example, it is quite likely that the source of the original Out of Memory error was really some corrupted program code. Many times, a Windows program with some damage to one or more components will cause exactly that error to be displayed. 

Invalid working directory Some Windows programs are extremely processing intensive. These programs require an area on the hard disk to store their temporary files while they work. This area is commonly known as a working directory, and the location of it is usually specified during that... 

General Protection Fault (GPF) A Windows error that typically occurs when a Windows program tries to access memory currently in use by another program. 

If the elution time(s) of peaks of interest are known and reproducible, the user can program most microprocessor-based fraction collectors to automatically collect only the peaks of interest and discard the be-tween-peak eluent or peaks of noninterest. This is a variable time window programming mode, also known as Time Program plus Time (or Drop) mode, and involves a sequence of time-based collection and drain steps, as shown in Fig. 2. Each collection step is commonly referred to as a collection time window. It conveniently allows the user to define time intervals during which the column eluent is either collected into fractions or discarded into waste. Each selected peak will be subfractionated by equal slices based on time counting or drop counting. Column void volumes, equilibration volumes, and peaks of no interest are discarded. 

CD ROM. Includes a surprisingly wide variety of crystallographic programs, and ports of DOS/Windows programs to Linux. Ref Kcristal Linux live CD for powder crystallography, V. H. S. Utuni, A. V. C. Andrade, H. P. S. Correa and C. O. Paiva Santos, J. Appl. Crystallogr., 2005, 38, 706 707... 

MCDM methods are applied when at least two responses need to be optimized simultaneously. Different approaches can be distinguished, for example, window programming, threshold approaches, utility functions. Derringer s desirability functions, Pareto optimality methods, Electre outranking relationships, and Promethee (7). In this chapter, only the Pareto optimality methods (7, 117, 118) and Derringer s desirability functions (7, 119, 120) will be discussed. 

The Bloch simulator is started using the pull-down menu command Utilities Bloch module... The main display window is shown in Fig. 4.23. The different representation modes are available from the corresponding commands of the Calculate pull-down menu opening particular dialog boxes. The FilelCopy to clipboard function offers the possibility to transfer the current graphical representation in the main display window to the Windows clipboard and then into other Windows programs.
