They are saved in the DELPHI32.DCI file, a text file in a rather simple format that you can edit directly.

(Actually, when I need to compare two Delphi units, I invariably use Beyond Compare—www.scootersoftware.com—a superb, low-cost file comparison utility written in Delphi.

However, the program won't run unless the proper DLLs (such as vcl70.bpl, which is quite large) are available on the computer where you want to run the program.Finally, some of the sample programs that ship with Delphi are actually useful tools that you can compile and keep at hand. After placing the frame in a form, you'll see it as if the components were copied to it. You must drag components from the Tree view to the diagram, which will automatically display the existing relations among the components you drop there. Another feature of the editor, code templates, is now language specific (your predefined Delphi templates will make little sense in HTML or C#).C# is the new language Microsoft introduced with its .NET architecture. This window has been considerably modified in Delphi 7.

Here, you can see an example of the structure of a menu in the tree:Executable file: the Windows application you've produced.Delphi's Object Repository.

Keep in mind that as you copy a project or form template to the Repository and then copy it back to another directory, you are simply doing a copy-and-paste operation; this isn't much different than copying the files manually.Type Library: a file built automatically or by the Type Library Editor for OLE server applications.At times, the TreeView also displays "dummy" nodes, which do not correspond to an actual object but do correspond to a predefined object. (nur mit aktivem 4G-Schalter, um bis zu 4 GB RAM nutzen zu können, anstatt maximal 2 GB)

See the references to online material in Appendix C for information about how to download a free chapter that discusses debugging in Delphi.Now, every time you need to create a message dialog box, you simply type Programmers can customize the Delphi IDE in various ways—typically, opening many windows, arranging them, and docking them to each other. To select child controls (say, the buttons inside a panel), drag the mouse within the panel while holding down the Ctrl key—otherwise, you move the panel. The only exception is when you change some project options, in which case you have to use the Build All command to put the new options into effect.If you open Delphi and cannot see the form or other windows, I suggest you try checking (or deleting) the desktop settings ( from Delphi's Delphi 7 offers another new feature. There is no way to modify the template definition itself, and it is certainly not possible to make the same change effective in all the forms that use the template. You can look at the entries already present under the Experts key to see how the path should be entered.Delphi will also add the SetValue method to the class declaration and provide a default implementation for it. Sie alle sind Teil der IDE (Integrated Development Environment, integrierte Entwicklungsumgebung).

(Strangely enough, these commands are not available in the shortcut menu of the Project Manager for the project group.)

Die Delphi 7 IDE ist 32 Bit, aber das ist egal, denn auch die aktuelle 10.4 IDE ist immernoch 32 Bit. These items are saved in a special file with the same root name as the project file and a .TODO extension.As I've mentioned, some of the IDE settings require you to edit the Registry directly. If you drop a Table on the form, you'll also see items that have next to them a red question mark enclosed in a yellow circle.

Programmers won't get a real advantage from this feature, because you could already open the binary DFM files in the Delphi editor with a specific command from the designer's shortcut menu. The code completion list uses colors and shows more details to help you distinguish different items. Desktop settings help eliminate problems that can occur when you move a project between machines (or between developers) and have to rearrange the windows to your liking. The table also shows when or under what circumstances these files are created and their importance for future compilations.Delphi doesn't always properly keep track of when to rebuild units based on other units you've modified. The most obvious way to write code in a visual environment involves responding to events, beginning with events attached to operations performed by program users, such as clicking on a button or selecting an item of a list box.

We'll also discuss a few traditional Delphi features that are … However, if you want to base a new project on one of the form objects or wizards, you don't need this form. Using arrow keys is particularly useful for fine-tuning an element's position (when the Snap To Grid option is active), as is holding down Alt while using the mouse to move the control. You can then modify the properties of that other component without having to select it. All the information is updated as soon as you begin typing in the editor.In both cases, Delphi executables are extremely fast to compile, and the speed of the resulting application is comparable to that of a C or C++ program.

This command is particularly useful in the form of a shortcut, Alt+End.

For example, if you type in a classYou can edit the textual description of a form, although you should do so with extreme care.

However, if you load the source file It might be required to merge Delphi with C++ compiled code ina single project.The Component Palette is used to select components you want to add to the current designer. Figure 1.2 shows my standard settings for the Preferences page of this dialog box.When you have too many pages in the Component Palette, you'll need to scroll through them to reach a component. Under this key, enter two string values, AutoPaletteSelect and AutoPaletteScroll, and set each value to the string '1'.Now we are ready to spend the next chapter looking into the Delphi programming language. Use the standard File ® Print command while the Diagram view is active, and Delphi prompts you for options as shown in Figure 1.7.

I don't have space in this book to cover debugging in Delphi; see Appendix C for information about extra material on this topic. A related feature of the Object Inspector lets you select the component referenced by a property.

This is a text file you can easily edit.
