在特定条件下如何显示或隐藏工具提示？ IWin32window赢了吗？

Question

I created a tooltip that's working how expected, the only problem is that sometimes i have to change a option, and i don't want him to show anymore.

I tried 2 things:

If the conditions wouldn't apply it would reset as

toolTip21.Hide(<programname>);

But it would reply a but saying that the programname doesnt exist in the context It was calling for a IWin32window, but since i'm a beginner i don't quite identify all the kinds of data. Even in msdn the information is very scarce

https://msdn.microsoft.com/en-us/library/system.windows.forms.iwin32window(v=vs.110).aspx

interface?? why not window?, or Form1, for example?

I also tried to hide it while in popup, but this was the result

Any hint? I smell noob stuff

The issue in your screenshot is that you cannot cast ToolTip to Control as it doesn't derive from it (The ToolTip component is not a control). However, you could cast the sender to ToolTip directly to use the Hide method, that is:

((ToolTip)sender).Hide(someControlWithTooltipBeingShown);

Still, this is probably not the solution you're looking for. If this is the only tooltip associated to you ToolTip component, you could play with its "Active" property and set it to true or false depending on if you want to show tooltips or not. You could do that when the RadioButton changes. If this is not your only tooltip, you could create a separate ToolTip component to handle just this tooltip and use the same method above. Hope this helps!
