  • Ext.app.application object is erased after initialization

    - by Queequeg
    I am trying to organize an existing extjs code in a more standard order (extjs wise). extjs version: extjs-4.0.2a. I've worked through the Extjs tutorial example and every thing went well. When I started working on the company's code I've notice there is no use of the application object there for I've added the Ext.application({...}); call. Ext.application({ name: 'FOO', appFolder: 'appFolderName', launch: function() { console.log('application was created'); } }); Upon loading the page I see the console.log output that is included in the "launch" function property - meaning the application object is created but when I look for it ("FOO" object) under the "window" object it is not there. Compering to the tutorial code the application object exist as a property of window. I encounter a few loading problems but I'm guessing the source of it all is this issue. What am I doing wrong? thanks.

  • How to remove margin at top of table?

    - by George Edison
    I have the following HTML: <div></div> <table> <tr><td>Test</td></tr> </table> ...and the following CSS: div { /* nothing yet */ } table { margin: 0px; border-collapse: collapse; padding: 0px; } No matter what I do, there is still a gap between the table and the DIV. This occurs on Google Chrome 5.0.375.70 beta on Linux. (And it seems to occur on other Webkit-based browsers too.) How can I get rid of the space?

  • Implications of trying to double free memory space in C

    - by SidNoob
    Here' my piece of code: #include <stdio.h> #include<stdlib.h> struct student{ char *name; }; int main() { struct student s; s.name = malloc(sizeof(char *)); // I hope this is the right way... printf("Name: "); scanf("%[^\n]", s.name); printf("You Entered: \n\n"); printf("%s\n", s.name); free(s.name); // This will cause my code to break } All I know is that dynamic allocation on the 'heap' needs to be freed. My question is, when I run the program, sometimes the code runs successfully. i.e. ./struct Name: Thisis Myname You Entered: Thisis Myname I tried reading this I've concluded that I'm trying to double-free a piece of memory i.e. I'm trying to free a piece of memory that is already free? (hope I'm correct here. If Yes, what could be the Security Implications of a double-free?) While it fails sometimes as its supposed to: ./struct Name: CrazyFishMotorhead Rider You Entered: CrazyFishMotorhead Rider *** glibc detected *** ./struct: free(): invalid next size (fast): 0x08adb008 *** ======= Backtrace: ========= /lib/tls/i686/cmov/libc.so.6(+0x6b161)[0xb7612161] /lib/tls/i686/cmov/libc.so.6(+0x6c9b8)[0xb76139b8] /lib/tls/i686/cmov/libc.so.6(cfree+0x6d)[0xb7616a9d] ./struct[0x8048533] /lib/tls/i686/cmov/libc.so.6(__libc_start_main+0xe6)[0xb75bdbd6] ./struct[0x8048441] ======= Memory map: ======== 08048000-08049000 r-xp 00000000 08:01 288098 /root/struct 08049000-0804a000 r--p 00000000 08:01 288098 /root/struct 0804a000-0804b000 rw-p 00001000 08:01 288098 /root/struct 08adb000-08afc000 rw-p 00000000 00:00 0 [heap] b7400000-b7421000 rw-p 00000000 00:00 0 b7421000-b7500000 ---p 00000000 00:00 0 b7575000-b7592000 r-xp 00000000 08:01 788956 /lib/libgcc_s.so.1 b7592000-b7593000 r--p 0001c000 08:01 788956 /lib/libgcc_s.so.1 b7593000-b7594000 rw-p 0001d000 08:01 788956 /lib/libgcc_s.so.1 b75a6000-b75a7000 rw-p 00000000 00:00 0 b75a7000-b76fa000 r-xp 00000000 08:01 920678 /lib/tls/i686/cmov/libc-2.11.1.so b76fa000-b76fc000 r--p 00153000 08:01 920678 /lib/tls/i686/cmov/libc-2.11.1.so b76fc000-b76fd000 rw-p 00155000 08:01 920678 /lib/tls/i686/cmov/libc-2.11.1.so b76fd000-b7700000 rw-p 00000000 00:00 0 b7710000-b7714000 rw-p 00000000 00:00 0 b7714000-b7715000 r-xp 00000000 00:00 0 [vdso] b7715000-b7730000 r-xp 00000000 08:01 788898 /lib/ld-2.11.1.so b7730000-b7731000 r--p 0001a000 08:01 788898 /lib/ld-2.11.1.so b7731000-b7732000 rw-p 0001b000 08:01 788898 /lib/ld-2.11.1.so bffd5000-bfff6000 rw-p 00000000 00:00 0 [stack] Aborted So why is it that my code does work sometimes? i.e. the compiler is not able to detect at times that I'm trying to free an already freed memory.

  • unwanted space before and after nested html table using Internet Explorer 8

    - by John
    I have an html table nested in an html table cell. I want the nested table to use the full size of the cell it is nested in. When I use firefox or google chrome I get the result I want but when I use Internet Explorer 8 (even if I use td style="height="100%") the height of the nested cell depends on it's content. As a result I get whitespace before and after my nested table.

  • Split string in C every white space

    - by redsolja
    I want to write a program in C that displays each word of a whole sentence (taken as input) at a seperate line. This is what i have done so far: void manipulate(char *buffer); int get_words(char *buffer); int main(){ char buff[100]; printf("sizeof %d\nstrlen %d\n", sizeof(buff), strlen(buff)); // Debugging reasons bzero(buff, sizeof(buff)); printf("Give me the text:\n"); fgets(buff, sizeof(buff), stdin); manipulate(buff); return 0; } int get_words(char *buffer){ // Function that gets the word count, by counting the spaces. int count; int wordcount = 0; char ch; for (count = 0; count < strlen(buffer); count ++){ ch = buffer[count]; if((isblank(ch)) || (buffer[count] == '\0')){ // if the character is blank, or null byte add 1 to the wordcounter wordcount += 1; } } printf("%d\n\n", wordcount); return wordcount; } void manipulate(char *buffer){ int words = get_words(buffer); char *newbuff[words]; char *ptr; int count = 0; int count2 = 0; char ch = '\n'; ptr = buffer; bzero(newbuff, sizeof(newbuff)); for (count = 0; count < 100; count ++){ ch = buffer[count]; if (isblank(ch) || buffer[count] == '\0'){ buffer[count] = '\0'; if((newbuff[count2] = (char *)malloc(strlen(buffer))) == NULL) { printf("MALLOC ERROR!\n"); exit(-1); } strcpy(newbuff[count2], ptr); printf("\n%s\n",newbuff[count2]); ptr = &buffer[count + 1]; count2 ++; } } } Although the output is what i want, i have really many black spaces after the final word displayed, and the malloc() returns NULL so the MALLOC ERROR! is displayed in the end. I can understand that there is a mistake at my malloc() implementation but i do not know what it is. Is there another more elegant - generally better way to do it? Thanks in advance.

  • Select fields containing at least one non-space alphanumeric character

    - by zzapper
    (Sorry I know this is an old chestnut; I have found similar answers here but not an exact answer) These are frequent hand written queries from a console so I is what I am looking for is the easiest thing to type SELECT * FROM tbl_loyalty_card WHERE CUSTOMER_ID REGEXP "[0-9A-Z]"; or SELECT * FROM tbl_loyalty_card WHERE LENGTH(CUSTOMER_ID) >0; -- could match spaces Do you have anything quicker to type even if it's QAD?

  • Maven easyb plugin java heap space settings?

    - by vinnu
    Hi, I attempted to change my heap size for maven easyb plugin http://www.easyb.org/maven-easyb-plugin/. In my easyb test I added standard code to print the heap size using the code Runtime.getFreeMemory() and Runtime.getTotalMemory(). I tried setting the MAVEN_OPTS=-Xmx1024m -Xms1024m and also set the maven opts in Maven surefire plugin. Now when I run the same class from the Junit I can see the getTotalMemory() displaying a number close 1Gig but the when the same classes are invoked from easyb plugin they do not reflect the memory size. Shouldn't there be a way of passing JVM opts to maven easyb plugin when it runs these easyb tests? At the very minimum it should atleast pick up the MAVEN_OPTS settings from the environment. Has someone bumped into problems like this? (A search on this group's archive does not reveal much)

  • What to use for space in REST URI?

    - by Droo
    What should I use: /findby/name/{first}_{last} /findby/name/{first}-{last} /findby/name/{first};{last} /findby/name/first/{first}/last/{last} etc. The URI represents a Person resource with 1 name, but I need to logically separate the first from the last to identify each. I kind of like the last example because I can do: /findby/name/first/{first} /findby/name/last/{last} /findby/name/first/{first}/last/{last}

  • Some little extra space is being added when a drop-down is on :focus

    - by catandmouse
    My problem is that when I place :focus style for our dropdown lists like so: input, select { margin: 0; padding: 0; } select:focus { background: #FFC; } ...the dropdown with the focused selection suddenly has an extra spacing on all sides (1-2px spacing). See images below: It may seem unnoticable on the photos above but when you do a selection, the increase in padding/spacing cannot be missed. I already tried removing margin: 0, padding: 0, thinking that the :focus state might be reverting to the padded version but still the same. Has anybody encountered this problem? Only happens in Firefox.

  • Have an external java application by notified of changes to Entity EJBs in JBoss AS

    - by John
    I'm trying to connect an external application to a JBoss AS container. The external application is a Java application that is currently being notified of changes to database entities through a JMS topic. I've added an EntityLifecycleListener class to all my entities that publishes a serialized (and unwrapped) copy of the entity to the JMS topic. The problem is that this implementation ignores the transaction boundaries of the JBoss container. For example, the @PostUpdate event can be fire, generating the JMS message for that entity, but the transaction could be rolled back causing the external application to be notified of an invalid change and become unsync'd. I need my external application to only be notified of successful commits to the database, but I need to be able to publish the entire java POJO to the external application. Is there an official way of doing this?

  • codingstyle "blanking after open and before close brackets"

    - by Oops
    Hi, I really like the "blanking after open and before close brackets"-codingstyle in modern codes Java/C#/C++ . e.g. calling a function: foo(myparam); // versus foo( myparam ); Do you have a better name for this codingstyle? where does it come from? Do you like it either, what is the reason for you to use it or not use it? a few years ago people said "you are blanking" if one has used too much blank space characters in a forumspost or email. many thanks in advance regards Oops

  • super-space-optimized code

    - by Will
    There are key self-contained algorithms - particularly cryptography-related such as AES, RSA, SHA1 etc - which you can find many implementations of for free on the internet. Some are written to be nice and portable clean C. Some are written to be fast - often with macros, and explicit unrolling. As far as I can tell, none are trying to be especially super-small - so I'm resigned to writing my own - explicitly AES128 decryption and SHA1 for ARM THUMB2. What patterns and tricks can I use to do so? Are there compilers/tools that can roll-up code?
