It introduces the Coreldraw 11 manual free download integrated development environment and many of its advanced features. This guide does not describe the basics of procedural programming, such as functions, conditional branching, and looping. How to use this guide This guide is organized into chapters that deal with specific aspects of automating tasks and building solutions in CorelDRAW.
This enabled solution developers to create intelligent mini-applications within CorelDRAW, such as ones that draw shapes, reposition and resize shapes, open and close documents, set styles, and so on.
VBA in CorelDRAW can be used as a platform for developing powerful corporate graphical solutions, such as automated ticket generators, customized calendars, and batch processing of files. Coreldraw 11 manual free download example, you can improve and customize some coreldraw 11 manual free download the built-in functionality of CorelDRAW alignments, transformations, object creationor add page layouts on-the-fly company letterheads.
VBA comes with a fully integrated development environment that provides contextual pop-up lists, syntax highlighting, line-by-line debugging, and visual designer windows. These coreldraw 11 manual free download prompts and aids create a particularly friendly environment for inexperienced developers to learn in.

The VBA toolbar in CorelDRAW The toolbar buttons provide the following functions: playing macros opening the VB Editor switching the VB Editor between design and run modes recording macros pausing coreldraw 11 manual free download recording of macros stopping the recording of macros These features are described in subsequent sections. To display the VBA toolbar, right-click anywhere on an empty toolbar area and choose Visual Basic for Applications from the pop-up menu.
Writing a macro Macros can only be written inside the VB Editor. Writing macros in the VB Editor Macros that are developed in the VB Editor can take advantage of full programmatical control, including conditional execution, looping, and branching. Macros that include this extra functionality are more than mere macros, but are programs in their own right. However, for the purpose of this guide, all VBA code is referred to as a macro, although in some contexts a macro is just those parts of that code that can be launched by CorelDRAW.
Recording macros It is often very useful to record macros, particularly when you are not familiar with CorelDRAW s object model, or when you are not sure which objects and methods to use. For many simple and repetitive tasks, recorded macros are a quick, efficient solution. Recorded macros are macros in the truest sense of the word: strictly speaking a macro is a recorded set of actions within the application больше информации can be repeatedly invoked.
This is exactly what is created when you record a macro a true copy of your actions within CorelDRAW, although this is limited to CorelDRAW actions, and does not simply record keystrokes and mouse moves.
Macro names must follow VBA s naming rules, which are: They must start with a letter. They can contain coreldraw 11 manual free download, but not as the first character. They must be unique within the chosen project. You can type an optional comment in the Description box. CorelDRAW is now recording every action each creation of a shape, each movement of an object and each change to a property is recorded.
To stop recording a macro, click Tools Visual Basic Stop. The macro will now be saved. To pause while recording a macro, click Tools Visual Basic Pause. Coreldraw 11 manual free download cannot be recorded because of their complexity, although they can usually be hand-coded in the VB Editor.
When something cannot be recorded, the following comment is placed in the code: The recording of this command is not supported. This will populate the Macro name list. VBA is both a language and an editor. It is not possible to have the language without the editor, nor is it possible to edit VBA in anything but the VB Editor. VBA is developed by Microsoft and is built into almost all of its desktop applications, including Microsoft Office. What is automation?
Automating repetitive tasks can save time and reduce effort, while automating complex tasks can make possible the otherwise impossible. In its simplest form, automation is simply recording a sequence of actions in CorelDRAW a macro that can be played back time and again.
The term 'macro' has come to include any code accessible to VBA running within the process, even though some of that code might be far more advanced than a mere set of recorded actions. Thus coreldraw 11 manual free download 'macro' is used in this guide, it refers to VBA functions and subroutines While it is possible to record a sequence of actions in CorelDRAW, the real power of automation and VBA is that these recordings can be edited to provide conditional and looping execution.
For example, a simple macro may set the selected shape s fill color to red and apply a one-point outline. But, by adding a condition больше информации looping to the VBA code, the macro could, for example, be made to visit each selected shape, and apply only the fill to text shapes and the outline to all other shape-types.
This means that it is a very easy language to learn, and it is helped in this by providing visual cues within the coreldraw 11 manual free download. The aim of this guide is not to teach you how to become a programmer - you must do that on your own. Before continuing reading this guide, you may find it useful to refer to the many books that have been written about VBA and Visual Basic.
And, since it runs 'in-process', it bypasses the interprocess synchronization mechanisms. This makes it run much more efficiently. All of the automation that is available to the in-process VBA is also available to external out-of-process automation controllers, or OLE clients.
This is intended to give experienced developers a quick grounding in VBA syntax and structure. Since VBA is a procedural language that shares much in common with all procedural languages, your current knowledge should help you get off to a quick start using VBA. This section is by no means exhaustive, but it does cover the most common syntactical nuances in which VBA differs from its peers. The following language topics are covered: variables, structures, enumerated types, arrays, and strings functions and subroutines line endings comments memory pointers and allocation passing values by reference and by value code formatting scope classes Declaring variables In VBA, the construct for declaring variables is: Dim foobar As Integer The built-in data types are: Byte, Boolean, Integer, Long, Single, Double, String, Variant, and several other less-used types including Date, Decimal, and Object.
Variables can be declared anywhere within the body of a function, or at the top of the current module. If the option Require Variable Declaration is set in VBA s options dialog, all variables must be declared before they are used.
This is generally good practice, since it enables the compiler to use an explicit type efficiently; if variables are coreldraw 11 manual free download used without being declared as a particular type, the compiler will create them as variants, which are less efficient at run time.
Booleans take False coreldraw 11 manual free download be zero and True to be any other value, although converting from a Boolean to a Long will result in True being converted to Data structures Data structures can be constructed using the following syntax: Public Type footype item1 As Integer item2 As String End Type Dim mytypeditem As footype The items within coreldraw 11 manual free download variable declared as type footype are accessed using dot notation: mytypeditem.
Arrays Coreldraw 11 manual free download are declared using parentheses, not brackets: Dim bararray coreldraw 11 manual free download As Integer The value defines the index of the last item in the array. Since array indexes are zero-based by default, this means that there are five elements in the above array zero thru four inclusive.
Arrays can be resized using ReDim, for example, the following code adds an extra element coreldraw 11 manual free download bararray, but preserves the existing contents of the original five elements: ReDim Preserve bararray 6 Array upper and lower bounds can be determined at run time with the functions UBound and LBound. Strings can be added together, truncated, searched forwards and backwards, and passed as simple arguments to functions. Strings in VBA are much simpler than strings in C.
Functions and subroutines VBA uses both functions and subroutines subs the difference between the two is that functions can return a value, whereas subs must not return a value. Declaring functions VBA functions and subs do not need to be declared before they are used, or before they are defined.
Functions and subs only need to be declared if they actually exist in external, system dynamic-linked libraries DLLs. Line endings VBA does not use a line-ending character. Many languages use the semicolon to separate individual statements; in VBA each statement must exist on its own line. Lines that end with a colon are labels used by the Goto statement.
Comments are started with an apostrophe and terminate at the line ending. If the original needs to be passed, either a memory pointer is passed that points to the original in memory, or a reference to the original is passed.
The same is true in Visual Basic, except that passing a copy of the original is called passing by value and passing a reference to the original is called passing by reference. By default, function and subroutine parameters are passed by reference. This means that a reference to the original variable is passed in the function s argument, and changing that argument s value within the procedure will, in effect, change the original variable s value as well.
This is a great way of returning more than one value from a function or sub. To explicitly annotate the code to indicate that an argument is being passed by reference, prefix the argument with ByRef. It is possible to force an argument to be copied instead of a reference passed, which prevents the function from changing the original variable s value. To do this, prefix the argument with ByVal, as given below. Modifying either argument within the body of the function will modify the original variable; however, modifying int1 will not affect the original, since it is a copy of the original.
Code formatting The VB Editor formats all of the code for you. The only custom formatting that you can do is /36510.txt change the size of indentations. Functions that are declared as Public are visible throughout all the modules.
However, you may have to use fully qualified referencing if the modules are almost out of scope, for example, referencing a function in a different Project. Any variables declared within the function are only available within the scope of the function itself.
Object-oriented classes VBA can create object-oriented classes, although these are a feature of the language and are not discussed in detail in this guide. The only operators that are different are is equal to and coreldraw 11 manual free download not equal to.
These operators also perform Boolean comparisons. However, VBA runs as an in-process automation controller, whereas the other languages are used to compile stand-alone applications apart from JavaScript.
VBA compared to Java and JavaScript VBA is similar to Java and JavaScript in that it is a high-level, procedural programming language that has full garbage collection coreldraw 11 manual free download very little memory-pointer support. They are also similar because code developed in VBA supports on-demand compilation. In other words, it can be executed without coreldraw 11 manual free download compiled. VBA has another similarity with JavaScript in that it cannot be executed as a standalone application: JavaScript is almost always embedded within Web pages, and the JavaScript is a mechanism that manipulates the Web browser s document object model or DOM.
