If you are at the beginning of the learning curve for programming CorelDRAW, a useful exercise is to record a few macros and see how they work and what the code looks like Before you start to program in VBA, let s examine a VBA macro that you ll create in the following section The term macro in this context means a series of recorded commands that imitate the user s actions A macro can be run (executed) any number of times, and the result should be the same every time

You can look at any macro, but it will be easier to understand how the code is written if you start with something very simple you record yourself So start by recording a drawing of a rectangle, about two inches wide by one inch high Here are the steps to record and save this action

2 Click the Record button on the Macros Toolbar, or choose Tools | Macros | Start
Recording
CorelDRAW X4: The Official Guide
3 Give the macro an obvious name, such as DrawRectangle Remember: don t use
any spaces or punctuation; the name must start with a letter and can only contain the characters A Z, a z, 0 9, and _ (underscore) You ll be reminded with an attention box if you don t type a valid macro name
4 In the Save Macro In section, click VBAProject (Learning Macros) the recorded
macro will be stored in the current document instead of in a global project file
5 Type in a brief description, such as Simple test macro; creating a rectangle 6 Click OK Don t be fooled by the lack of activity at this point VBA will record
every action that you take from now until you stop
7 Choose the Rectangle Tool (F6), and then draw a 2 1" rectangle in the approximate
center of the page; accuracy is not important in this example
8 Choose Tools | Macros | Stop Recording or press CTRL+SHIFT+O or click Stop
Recording on the Macros Toolbar That s it; you can now play back the macro to create a new rectangle each time at the same position as the original This is not the endgame, however the goal is to generate a few macros you can view to gain an understanding of what s written in the macro document Let s quickly make another macro You ll use these simple macros as a basis for your work in the rest of this chapter You will write a macro that performs functions that cannot be captured by the macro recording process With the rectangle from the preceding section selected, record the application of a 3-point-thick blue outline and a Uniform red fill; call this macro RedFill_BlueOutline Stop the recording Create a different shape, select it, and run this macro: the red fill and blue outline are applied to the new shape The lesson you are about to work through is an example of how you can record approximately what you require as a macro, and then through a little text editing, modify the macro later
Solving Macro Needs with VBA
Now you ll take a look through the code that you recorded a few sections ago Shortly you ll optimize the RedFill_BlueOutline macro Then you will create an advanced macro, using the optimized RedFill_BlueOutline as the foundation This advanced macro will apply the fill and outline to the selected objects However, it will apply the fill only to those objects that have a fill already, and it will apply the outline part only to those objects that have an outline already This will demonstrate how a little VBA programming can be a more powerful resource than the Find and Replace in CorelDRAW when it comes to automating your work
Viewing Macro Code
To view the VBA code that CorelDRAW created when it recorded your macro, you need to open in the Macro Editor, also called the Microsoft Visual Basic Editor, the project in which

the macro is stored Open the Macro Editor by pressing ALT+F11, or click on Macro Editor on the Macros Toolbar Look for VBAProject (Learning Macros) in the Project Explorer pane on the left side of the editor window Each open document that has a macro stored in it, as well as the global macro project files that are stored in the GMS folder, is listed here Expand the listing for the VBAProject (Learning Macros) Click on the plus button to expand the Modules entry Under the Open The Modules section you will see a listing, RecordedMacros Each time you record a macro in this document, it is added to the RecordedMacros module Double-click on the RecordedMacros entry in the tree listing, and a document window opens to the right, with the name of the VBAProject file, Learning Macros - Recorded Macros (Code) on the title bar This document window contains the actual programming code that you recorded that makes the macro work
