问题 In order to enhance the readability of our text, it has been suggested that we outline the text of label controls. I know you can stroke Text shapes, but we went with Labels. I forget why, but I think it was because there was something a Label could do for us that a Text Shape could not.

Is there anyway to make

C# label AutoSize adds padding

阅读更多关于 C# label AutoSize adds padding

问题 I have a Label on a Windows.Form. I set the AutoSize property on the label to True and I noticed that when I do that, it pads the right hand side with ~5px of white background. I have the Padding property set to [0, 0, 0, 0]. Is there a way to get rid of this?

问题 I'm writing a C compiler, and when I come to the implementation of the switch statement one constraint confused me a lot. Section 6.8.4.2p2 of the standard states: If a switch statement has an associated case or default label within the scope of an identifier with a variably modified type, the entire switch statement shall be within the scope of that identifier. With a footnote: That is, the declaration either precedes the switch statement, or it follows the last case or default label
