| Button FlatStyle.Flat bug (2 replies) |
| microsoft.public.dotnet.framework.windowsforms |
| When a button has its FlatStyle set to Flat, it changes color when the mouse is over it. However, if you have such a button on a dialog that is closed, retained in memory, and reopened, the color change stops working. Same in Framework 1.1 final beta. To reproduce: Have a winform project with 2 forms. On the second form place several buttons, with Flatstyle set to Flat. I also gave one of the butt... |

So, I used ILDASM and found: private void ShowContextMenu() { // code to show the context menu } So, I have 2 questions: 1. Why is th... |

| Localization of Help bug in VS.NET (3 replies) |
| microsoft.public.dotnet.framework.windowsforms |
| This has been brought up, apparently as early as Nov. of 2001, and the bug still exists, so I'm curious if anyone knows if MS has any intention of fixing this, or if those of us doing localizable apps are simply screwed? Basically, if you add a help provider to a localized form, the code it inserts is faulty and won't compile. Essentially, calls to SetHelpKeyword and one other method, fail because... |
