Comment on Calculate the Nth root of a number in C#

Rod Stephens — Wed, 01 May 2013 15:57:55 GMT

The intent here was to just do the job, not to show how to calculate the number yourself. If you do want to do it yourself, you can use Newton's method as shown in this example:

Use Newton's method to find the roots of equations in C#

Simply find the roots of the equation Y = X^N.

Or you can use subdivision. Pick an upper and lower bound, perhaps lower = 1 and upper = N / 2. Then check the value in the middle M. If M^N > N, set lower = M and repeat. If M^N < N, set upper = M and repeat.

Either way it still doesn't need to be recursive, though.

This uses the math features of C#. This does not do it recursively. Those are the reasons I disliked this.

Comment on Remove the X Close button from a form's system menu in C#

Rod Stephens — Mon, 01 Apr 2013 02:37:49 GMT

True. You are usually better off removing the menu and X by setting the form's ControlBox property to false. Of course then you also lose the minimize and maximize buttons.

Or you can catch the form's FormClosing event, figure out why the form is closing, a prevent it if the user didn't use the button or whatever that you provided.

Probably the best bet is to either leave the Close item and X there and deal with it in FormClosing, or remove the whole control box.

(The X button has been a bit of a headache for quite a few years.)

While this does remove the Close system menu item, it does not work to "Remove the X Close button from a form's system menu in C#". Note: the 'X' button is still visible. This only disabled the button.

Comment on Draw a simple robot arm in C#

I'm not sure. My guess would be that the PictureBox's Paint event isn't hooked up to the code properly.

Most of the examples on this web site only include the most interesting pieces of code and often there is other code that you need to include to make them work. To see all of the code, you should download the example program by clicking the Download button below the text. I suspect the example will work for you.

Thanks, this was the only one code that resolve my problem.

Comment on Use steganography to hide one picture inside another in C#

Robert Gawron — Thu, 07 Mar 2013 19:42:47 GMT

Hi,

I implemented this algorithm in Python, in my version both images have the same sizes and the data of hidden image is stored on only two lowest bits.

The result (=quality) is a bit worse, it can be checked below, the source code in Python is also available:

How to hide an image inside another image?
