phpMyAdmin: Can't import huge database file, any suggestions?

阅读更多关于 phpMyAdmin: Can't import huge database file, any suggestions?

I recently got a new computer, so I thought I'd move all my web projects over. Moving the files was easy, however, moving the database seems to be a bit harder. I exported ALL databases using phpMyAdmin, and saved it to localhost.sql. Then I tried to import it on my new computer also using phpMyAdmin, and I get the error: No data to import. Either no filename was sent or the filesize exceeded the maximum allowed size. See FAQ 1.16. (This was translated from Swedish) I took a look at the FAQ, as advised. And they mentioned a tool called BigDump. So I downloaded it, and after looking at the

Set element width or height in Standards Mode

阅读更多关于 Set element width or height in Standards Mode

Is it possible to set width or height of HTML element (ex. <div> ) in JavaScript in Standards Mode? Note the following code: <html> <script language="javascript" type="text/javascript"> function changeWidth(){ var e1 = document.getElementById("e1"); e1.style.width = 400; } </script> <body> <input type="button" value="change width" onclick="changeWidth()"/> <div id="e1" style="width:20px;height:20px; background-color:#096"></div> </body> </html> When user presses the change width button, the <div> 's width should change. It works fine when doctype declaration determines Quirks Mode. In

how to find 2d array size in c++

阅读更多关于 how to find 2d array size in c++

问题 How do I find the size of a 2D array in C++? Is there any predefined function like sizeof to determine the size of the array? Also, can anyone tell me how to detect an error in the getvalue method for arrays while trying to get a value which is not set? 回答1: Suppose you were only allowed to use array then you could find the size of 2-d array by the following way. int ary[][5] = { {1, 2, 3, 4, 5}, {6, 7, 8, 9, 0} }; int rows = sizeof ary / sizeof ary[0]; // 2 rows int cols = sizeof ary[0] /

阅读更多关于 How to set limit on directory size in Linux? [closed]

问题 Closed. This question is off-topic. It is not currently accepting answers. Want to improve this question? Update the question so it's on-topic for Stack Overflow. Closed 8 years ago . I have read about limiting size of directory - like creating big files, formatting,mount,.. etc. But this all very complicated. Does exist utility or something else to set limit on already existing directory? 回答1: Quota is based upon filesystems, but you can always create a virtual filesystem and mount it on a

Actionbar Logo size?

阅读更多关于 Actionbar Logo size?

问题 In the Google I/O 2012 Android App an actionbar logo is used instead of the normal app icon. In the open source project I could find the image which is 340x72 and present only in this dimension. I searched if there is some specified size for using a logo in the actionbar, but I did not find anything. Do you know something about this? 回答1: I looked into the resources of the YouTube app, since that seems to be the only official Google app (besides I/O) that uses an action bar logo at the moment

Can I make Eclipse on Ubuntu look more compact? [duplicate]

阅读更多关于 Can I make Eclipse on Ubuntu look more compact? [duplicate]

Possible Duplicate: Gigantic Tabs in Eclipse on Ubuntu Back when I was using Eclipse on Ubuntu 10.04 LTS, I found that the tabs and bars used a bit too much vertical spacing, which made the interface a bit too spacey for my taste. However, I didn't find a good way to make this right, and I learned to work with it. But now, after installing Ubuntu 12.10 (or actually Linux Mint 14 Cinnamon), it has gotten even bigger, the vertical spacing. If you have three tabbed windows with two toolbars in your normal vertical workspace, this easily hides 6 lines of code with useless UI spacing, which I

How does this piece of code determine array size without using sizeof( )?

问题 Going through some C interview questions, I've found a question stating "How to find the size of an array in C without using the sizeof operator?", with the following solution. It works, but I cannot understand why. #include <stdio.h> int main() { int a[] = {100, 200, 300, 400, 500}; int size = 0; size = *(&a + 1) - a; printf("%d\n", size); return 0; } As expected, it returns 5. edit: people pointed out this answer, but the syntax does differ a bit, i.e. the indexing method size = (&arr)[1] -

How to double the size of a matrix and propagate its elements in Matlab?

阅读更多关于 How to double the size of a matrix and propagate its elements in Matlab?

suppose I have a matrix like this: a = 1 2 3 4 I want to double the size of matrix and create something like this: aa = 1 1 2 2 1 1 2 2 3 3 4 4 3 3 4 4 in this way, each element in the first matrix propagates to four elements in the bigger matrix. a(i,j) == aa(2*i-1, 2*j-1) == aa(2*i , 2*j-1) == aa(2*i-1, 2*j) == aa(2*i , 2*j) is there any predefined functions to do that? definitely I can do that by two loops, but I want the easiest and cleanest way! use kron - Kronecker tensor product: kron(a,ones(2)) ans = 1 1 2 2 1 1 2 2 3 3 4 4 3 3 4 4 来源： https://stackoverflow.com/questions/14576007/how

My JFrame always becomes a few pixels too big.

阅读更多关于 My JFrame always becomes a few pixels too big.

I am working on this game in Java, and I just rewrote all my window related code from being based on java.awt to javax.swing. Soon after, I realized that things were a bit more complicated now, and so i did some research and and found out how to draw things, how to set the size of a JFrame, etc. But for some reason, the size of my JFrame always goes 10 pixels beyond the size I've specified it to become. In this case, I wanted it to be 640 by 640 pixels. Here's my code: package chrononaut; import java.awt.*; import java.io.IOException; import javax.imageio.ImageIO; import javax.swing.*;
