- First of all (with IE7) there is no “draw” button anywhere on my screen!

- I got the same error that Ole got, it also shows when I enter: 50 and 99 and 100.00.01 (more then one .)

- I can enter many digits in one field, if I enter more then 7 digits (in any of the fields) I get a message that the triangle is invalid. It would be much more user friendly if it’s not possible to enter more then 7 digits.
The “test data history” only shows the first seven of all digits that I have entered (or is that a bug in the test-software? ).

I updated the link to point to the new location: a new ajaxified version.

The post is quite old, but too bad the page is not present anymore to see the application.

Another bug found:
If we enter values like
Side 1: 2,
Side 2: 3,
Side 3: 5 & on clicking Draw button
It displays invalid triangle.
Rather it should say Scalene triangle.

When I enter 3 special characters in the three different sides for instance :
Side 1: @,
Side 2: $
Side 3: %,

and on clicking Draw button displays Triangle Type: Scalene.

This is wrong it Either it should not accept special characters or it should show Triangle Type: Invalid.

Same problem if I enter any other special characters in any sides say #,* etc.

Hi,

I have not tested it so much but, still i found one bug related to integer values. When we enter values like 2\6\4 or 3\7\4 or 4\8\4 or 5\9\4, it shows invalid triangle. it should not be invalid.

Hi! I live in Sweden and we use “,” for decimals and not “.”.

1) Enter “1,23″ in field “Side 1″, “Side 2″ and “Side 3″.
2) Click button “Draw!” => Error

Triangle is just a line.

Elisabeth:>Since I wrote the triangle code and have tested it a bunch of times, I thought I knew where the bodies were buried.

Spoken like a true developer! [grin]
