Hello! I'm gonna showcase my Captcha System.
I created this because all the tutorials online used a pre-made base image and I just wanted to see if I could do this completely in Vb.net

You can :
• Choose colors for the text, background, lines, and dots.
•Change the amount of Dots or Lines you have in your captcha image.

The color picker was something I quickly came up with, The project would have been fine without it. I might also it up and release it in a different thread.

So here is how it looks like :

Press the INFINITY button beside the textbox to generate a image. Use the Play button to submit.

Special 200th post!

I sorta did The textbox under the generated image was used to check it.
Press the Play button to enter, and the Infinity button to generate a new image

Great start. I recommend taking the chars and positioning them -almost- randomly instead of completely horizontal.

Lol yea I tried to make it Multifont so like one character is Ariel the next would be like Segoe UI Semibold and so on but I thought would be too much for 1 night. I do plan on doing that.

Nice work and a great idea never seen this done before in .NET

Not really a whole need for it really.
Perhaps for some random thing you could, but relying on external services is a better idea.

Looking good.
Randomizing the color of each letter would make it significantly harder to bot.

This captcha would be easy to OCR. Try tilting the characters or placing them in random positions and try using colors that contrast less.

transparent background will prevent using ocr
