Hello world! I'm talking about adding tooltips to your C# project. I've started a new project and I have a couple of buttons, a label, and a picture box. and usually in a Windows program if you move your mouse over a button or something, it has tooltip that appears and you can see it says there "open file" This one says " new project", and so on. but when I look at this button and I go to tooltip there's nothing there. there's no option to put on a tool tip. The way it works is, I need to go to the toolbox and add tooltip to the form . and it doesn't actually appear on the form. It appears down below, this is a resource now that we can use. If we go back to button1 and go to the properties Now you'll see tooltip on tooltip1. And I'm going to just make that say "click me" and run my program and when I move the mouse over the button you can see it says "click me" We can also add a tooltip to a label and to a picture box. Let's go to properties, and for the picture box... I'm going to have a tooltip that says "picture of something" I didn't actually add anything there. And for the label I can say the tooltip is "extra information" And we can run this again, And you can see each of them has I didn't add one for that. There's a picture box down here somewhere, There it is. Let's go back to select tooltip. And then go to its properties. And there are a number of things that you could set: the amount of time you want to delay, the pop delay, the back color, the fore color, Oh, let's change that, to red, just so we can see that. And isBalloon, let's change that to true. and.. a number of things that we can add an icon for the tooltip. So let's run our program again, and that now says "click me" as a balloon. and also a balloon Where's my picture box? "picture of something" and that's what that isBalloon did for us. And we can toggle that one and off. Put it back to normal. But, maybe if you were doing a game for kids, you might want to make that a balloon. And that's it, that tooltips.
