Random number stays the same

Remco Peters

In lesson 4 I noticed that the generated key the user sees in the inputscreen is the same twice: 170554. When downloading the sampledatabase in the lesson, on opening I also got this code 170554 as key everytime I opened the inputscreen.

I added "Randomize" to my VBA in the doRegister private sub BEFORE the Key1 declaration and now it does randomize.

Is this a known error and right solution or am I seeing this wrong?

Yeah, I talk about this in the video. The random numbers in any computer program aren't really random, so if you start a computer and start a database and redo that cycle, you're going to get the same random number over and over again. So you need some kind of natural means of initializing when that randomize action takes effect - something like a keystroke, a mouse click, or even going out to the web to get the current time to the second, or something like that.
