How do I make a form implement an interface?
Everything makes sense in someone's mind
|
|

Forms are normal classes. So you can implement an interface as usual.
|
|
|
|

You may be having trouble because your form class is already "implementing" the Form class. What you need to do is enter a , after the Form declaration and type your interface name there. Example:
partial class myForm : Form, myInterface
{}

Nope its inheriting. You inherit base clases you implement interfaces.

Thanks for the correction.

What would be the easiest way of drawing rectangles or other shapes onto a picture box using the mouse?
Just like in MS Paint.
|
|
|
|
|
this[^] might help
While (true) { Human.isLearnable = true; }
|
|
|
|
|
No, not suitable for your question but it's obvious!
While (true) { Human.isLearnable = true; }
|
|
|
|
|
Or maybe this[^]
While (true) { Human.isLearnable = true; }
|
|

I looked at both of the links, seems it could be easier.

Did you do that right now? You're amazing!

What do you mean? Do you have any idea?
While (true) { Human.isLearnable = true; }

Yes, very simple. Click on a button then on a picturebox and a rectangle would appear.
|
|

Well, it's too simple. I thought you said "like MS Paint" (actually you did!). However for your reason you should call PictureBox_Paint in Button_Click (be careful of parameters) and use e.Graphics.DrawRectangle(Pen pen, int x, int y, int width, int height) (+2 overload(s)) to draw a rectangle.
Or you have something else to say? 
While (true) { Human.isLearnable = true; }

I did this using MouseDown, MouseMove, MouseUp and Paint event. And ofcourse a graphics object.

could you give some examples?

Its too big of a code to share. Actually its all mixed with lot of other code that I use for drawing other stuff. I can tell bit of logic though.
1. Grab the coordinates at MouseDown
2. On MouseMove draw rectangles calculating the height and width using the graphics object.
3. On MouseUp get the point to find final hieght and width and keep them for using in Paint event.
4. Redraw final rectangle in Paint event.
You can also place a PictureBox identical to final rectangle in case you want to have some events for the rectangle.

I know how to draw a line and I have that code, I don´t know how to get a rectangle or some other form to show on a picture box.

how can i show a caret inside the listbox, perhaps a horinontally in between the listbox items.

dude...you got to take it easy. Where do you see the Urgent.

You can't with the standard ListBox. Google for editable listbox c#[^] and you're bound to find something.
DaveBTW, in software, hope and pray is not a viable strategy. (Luc Pattyn)Visual Basic is not used by normal people so we're not covering it here. (Uncyclopedia)

I found nothing....they are telling how can you make an editable listbox. I am controlling the listbox paint method but couldn't find the right direction how to add a caret.
Is that even possible with listview.
|
|
|
|
|
why else would you want a caret except to show the current text insertion point i.e an editable listbox?
