Happy Valentine's Day! by Erick Tejkowski

What would Valentine's Day be without a valentine from your friends at ResExcellence? This week we'll look at how to make an electronic valentine with REALbasic.

Build the Interface

Launch REALbasic, open Window1, and add a Canvas and Timer control to the window. Give the Canvas dimensions of 202 x 196. Set the Timer's Mode to a value of 2 and Period to 500. Download this flickerFreeCanvas class and drag it into your project. Then, change the Super property of the Canvas in Window1 to flickerFreeCanvas.

Next, create a black and white image of a heart shape. If you aren't a good artist, you can download one here. Drag the image into your REALbasic project. Note that the image file I am using for this example is named "heartblack".

Add the Code

Double click Window1 to open its Code Editor. Select Edit-New Property and create a new picture property, named p.

Finally, navigate to the Action event of Timer1 and add this code

dim c as color
dim r,b as integer

r = rnd*255
b = rnd*100

p=newpicture(202,196,32)
p.graphics.foreColor=rgb(r,0,b)
p.graphics.fillrect 0,0,202,196
p.Mask.Graphics.DrawPicture heartblack,0,0

Canvas1.mPicture = p
Canvas1.Redraw

Conclusion

You can download the finished product if you don't feel like recreating the project. Happy Valentine's Day and see you next week!

Sockets? Super! Essence Software is proud to announce the immediate availability of SuperSocket 2.1 for REALbasic!

SuperSocket is the premier networking toolkit for REALbasic, providing support for active listening TCP, UDP, ICMP (Ping), AppleTalk (ADSP & DPP), and DNS.

RTF for all! Belle-nuit has announced a new version of their RtfParser classes.

The RtfParser is a collection of classes to parse RTF files to use in REALbasic applications. The Rich Text Format is the major interchange format between word processing programs of all major platforms. It is called richt text, because it cannot only hold text, but also formatting information. Also, it provides encoding for special characters and encodes them to a 7bit-textfile, so that it can be sent safely over Internet.

RBScript Regex Classes John Balestrieri has posted a REALbasic class and some RBScript wrapper code that lets you create and use RegEx classes within RBScript.

RB3DSpace Spinner is a simple application to demostrate the use of REALbasic's new 3D graphics facilities. It uses a RB3DSpace to display a spinning cluster of particles. You can use it to explore the use of properties like FieldofView, Yon and Hither.
