Hints n' Tips

Hints n' Tips

Here are some great hints n' tips for three of the most popular programming languages around. Most of them will be focused on Delphi (Pascal) because this is the language I use most frequently but I will try to include what every information I stummble across that has to do with VB or C/C++.

Delphi

Visual Basic

C/C++

Delphi

A tip, relating to my current Delphi Example, for making masks a little easier is 'Draw' the sprite to the canvas using the 'cmNotSrcErase' copy mode, from there change all the gray to white. Any black on the sprite will apprear gray you will have to colour this in black manually on the mask. This only works with 16-bit picture or lower.
Anybody looking for a good beginners to programming in Delphi I recommend 'Delphi by Example' by Que. It starts with the very basics and continues on to complex topics in a very easy-to-understand exercises. Even for accomplished programmers it teaches great technique.

Visual Basic

To use Visual Basic to make screen savers just turn of all border icons, write code to close it on 'mousemove' and on 'keypress'. When the form is created test the command line for /c and /s (/c is for the configuration, /s is to start the screen saver). Then when you make your program an execute file change the extention from (*.exe) to (*.scr) and put it in the windows directory, from here you can just run it as a normal screen saver. (This method can also work for Delphi but I am yet to see it work, but if you are interested follow this link.)

C/C++

Have a look at these great C tutorials (chapter 1 to 4).
