I can't find any documentation on this message and I have no idea what is overflowing exactly. Can anybody help me figure out what the problem is? Is this a problem of valgrind, or of my program? 回答1: Line 1327 from the valgrind source code points to the user manual, "see section Limitations in user manual"

Is there a way to prevent this so that any partial lines do not show-up. Almost like a vertical word-wrap. 回答1: You can use wrapper div and multi-column css: .wrapper { -webkit-column-width: 150px; //You can't use 100% column-width: 150px; height: 100%; } Solution example: http://jsfiddle.net/4Fpq2/9/ Update 2017-09-21 In Firefox this solution still works but broken in Chrome. Recently Chrome started break column by small parts, also stop

I have had some success, as you can see on the example below, I have managed to apply the skew to a couple of the elements on the page. Currently the Skew is applied to both the top and bottom of the containers and it seems to stop half way through the bottom and top then go back to straight edge. What I am looking to achieve is for the top edge to be straight and the bottom edge to be skewed, for example: * { padding: 0; margin: 0; } #main-slideshow { position: relative; z

It seems that jqgrid's default is to have the overflow hidden and to not have the text wrap to new lines (if needed). Is there a way to allow jqgrid cells to expand as needed? 回答1: Had the same problem, this isn't answered and came first in google, so here it is: /* your grid discriminator*/ tr td { white - space : normal ; height : auto ; } I also found recommendations of overflow: normal ; this isn't even legal css; it's not in W3C's list and FireBug ate

The only option I have found is to change the icon permanently by adding a custom style. The problem is that in the nearby future we will need to change this during the use of our app. Our app is an extension to a series of online-platforms and therefore a user can enter their platform's web-url. These have their own styles and will be fetched by an API call towards the app. These might adress me to change the color of the icon...

So lets say I write a small wpf app which just references X.dll. And in the window's constructor I access something inside X.dll (ie. in some namespace in X.dll). On doing this i dont catch any exception and it seems like things are going on as expected. But upon returning the control to .NET runtime, I get an exception in Application class's 'DispatcherUnhandledException' handler : “Overflow or underflow

If num_actions_to_skip is set to 1, instead of 2, the error goes away. Thanks error: assuming signed overflow does not occur when assuming that (X - c) On if (loc >= 0 && loc const QList &action_list = tool_menu->actions(); static const int num_actions_to_skip = 2; const int loc = action_list.count() - num_actions_to_skip; if (loc >= 0 && loc insertAction(action_list.at(loc), action); } It started with Q_ASSERT_X(i >= 0 && i at qlist.h:454,

This also fails: Dim giveTime As Long giveTime = 24 * 60 * 60 Why is this? giveTime is declared as a Long type, so 24 × 60 × 60 = 86400 should comfortably fit. 回答1: This is a really odd VBA quirk. I'm amazed I've never bumped into this. Dim x As Long x = 24 * 60 * 60 ' Overflow x = 32767 + 1 ' Overflow. x = 32768 + 1 ' Works fine! So it looks like the * and + operators return an Integer in the first two examples. Sure enough,
