Java multiply operation behavior

由 心已入冬 提交于 2019-12-09 16:11:51
问题 I wrote a method to convert a given number from days to milliseconds: private long expireTimeInMilliseconds; ... public void setExpireTimeInDays(int expireTimeInDays) { expireTimeInMilliseconds = expireTimeInDays * 24 * 60 * 60 * 1000; } I had a hard time to figure out what I did wrong. Now my question: Is that error so obvious ? The corrected method: private long expireTimeInMilliseconds; ... public void setExpireTimeInDays(int expireTimeInDays) { expireTimeInMilliseconds = ((long)

Flexbox child with “overflow: hidden” overflowing grandparent margins

由 拥有回忆 提交于 2019-12-09 14:42:39
问题 I'm trying to nest two child elements in a wrapper which specifies side margins so there's space between its contents and the sides of the screen when the display is narrow and a max-width for when the display is wide. The second child has some overflow which should be visible while the first child should stay strictly within the wrapper's content box. With the first child removed, the second child behaves as desired. When I add in the first child though, it seems to completely ignore the

What is the function of “overlay” value of “overflow” property? [duplicate]

由 梦想与她 提交于 2019-12-09 08:44:34
问题 This question already has answers here : Overflow: overlay doesn't work in firefox (2 answers) Closed 2 years ago . I am unable to understand the difference between "overlay" & "auto". Does "overlay" does the same work as "auto"? 回答1: The only difference is that overflow: overlay is only supported by -Webkit browsers, is non-standardized, and allows the content to extend beneath the scrollbar - whereas overflow: auto will not allow the content to extend beneath the scrollbar, if it appears it

VB6 overflow error with large integers

由 你离开我真会死。 提交于 2019-12-09 07:50:02
问题 I am trying to set an integer value as such: Dim intID as integer intID = x * 10000 This works ok when x is 3 or less. But when x is 4, this gives me the error: run-time error 6 Overflow I don't understand why this is. I can set intID to 40000 directly without any problems, so it's obviously capable of storing large numbers. 回答1: You *cannot set a vb6 integer to 40000 as they are signed 16 bit numbers so +32767 is the maximum. Long is the 32 bit type. However as a caveat, if you were to: Dim

No useful and reliable way to detect integer overflow in C/C++?

由 邮差的信 提交于 2019-12-09 05:22:04
问题 No, this is not a duplicate of How to detect integer overflow?. The issue is the same but the question is different. The gcc compiler can optimize away an overflow check (with -O2), for example: int a, b; b = abs(a); // will overflow if a = 0x80000000 if (b < 0) printf("overflow"); // optimized away The gcc people argue that this is not a bug. Overflow is undefined behavior, according to the C standard, which allows the compiler to do anything . Apparently, anything includes assuming that

sprintf function's buffer overflow?

由 淺唱寂寞╮ 提交于 2019-12-09 00:30:28
问题 { char buf[8]; sprintf(buf,"AAAA%3s","XXXXXXXX"); printf("%s\n",buf); } what will happen? The buffer have 8 characters space and only 3 free characters left, however, "XXXXXXXX" is 8 characters long. I take a test with Visual Studion 2008 on Windows 7. As a result, the program printed:AAAXXXXXXX, and a run-time error happened. 回答1: It makes a lot of sense to consider what happens in your and, more importantly, similar, cases. As other posters have noted, it invokes UB. That's probably true.

Clip child to parent element with border-radius

由 不问归期 提交于 2019-12-08 20:51:41
How do I force clip a child to a parent element that has rounded corners. <div class="item" > <div class="top"> <h1>Tile</h1> <h2>Click me</h2> </div> <div class="behind"> <h3>Details</h3> </div> </div> When animating the child, its ignores the border-radius of the parent element. Is there a way to fix the two corners on the top? .item{ text-align: center; cursor: pointer; overflow: hidden; height: 280px; width: 280px; float: left; border-radius: 5px; background: white; margin: 10px; position: absolute; } .top{ z-index: 1; position: absolute; height: 280px; width: 280px; background: #ed844b;

<div> overflow:auto does not show scrollbar until resize

由 故事扮演 提交于 2019-12-08 16:14:54
问题 I have a element on my form that looks like this: <div style="overflow-y:auto;overflow-x:hidden;height:100%;width:100%"> In IE7 when the page first renders, there are no scrollbars. However, if I resize the page (even just 1 pixel) the scroll bars appear properly. Is there something I can do so that the scrollbars show properly when the page first displays? 回答1: Set overflow-y to "scroll" if you always want a scrollbar. 回答2: That's the kind of problem which comes from the hasLayout bug in IE6

How to find out the current overflow-checking context?

由 只谈情不闲聊 提交于 2019-12-08 15:59:19
问题 Is there a way to do this in C#? So for example, if your method is called and you want to know if the caller had put the method call inside a checked block? 回答1: checked / unchecked blocks are always local to the method. The keywords influence how IL is generated for the statements and expressions in the block. It doesn't propagate to methods called, and there is no way to determine at run-time if a method was called from such a block. It's a compile-time feature. 来源： https://stackoverflow
