  • How do you give variables reference in javascript?

    - by Eric
    I want to give variables reference in javascript. For example, I want to do: a=1 b=a a=2 and have b=2, and change accordingly to a. Is this possible in javascript? If it isn't is there a way to do like a.onchange = function () {b=a}? What I wanted to do was make a function like makeobject which make an object and puts it in an array and than returns it like function makeobject() { objects[objects.length] = {blah:'whatever',foo:8}; } so than I could do a=makeobject() b=makeobject() c=makeobject() and later in the code do for (i in objects) { objects[i].blah = 'whatev'; } and also change the values of a,b and c

  • How to give you website customers a secure feeling

    - by Saif Bechan
    I was wondering how you can give your website customers the confidence that you are not tinkering with the database values. I am planning on running a website which falls in the realm of an online game. There is some kind of credit system involved that people have to pay for. Now I was wondering how sites like this ensure there customers that there is no foul play in the database itself. As I am the database admin i can pretty much change all the values from within without anyone knowing i did. Hence letting someone win that does not rightfully is the winner. Is it maybe an option to decrypt en encrypt the credits people have so i can't change them. Or is there maybe a company i can hire that checks my company for foul play.

  • How do I give MacPorts privileges?

    - by cojadate
    I tried to install PostgreSQL server development libraries using MacPorts and got the following: Warning: MacPorts running without privileges. You may be unable to complete certain actions (e.g. install). ---> Computing dependencies for postgresql-server-devel ---> Dependencies to be installed: postgresql-devel ---> Building postgresql-devel Error: Target org.macports.build returned: shell command failed Error: The following dependencies failed to build: postgresql-devel Error: Status 1 encountered during processing. To report a bug, see <http://guide.macports.org/#project.tickets> So I guess that means I need to running MacPorts with privileges and try again. Unfortunately I've no idea how to give MacPorts privileges. I'm running OS X 10.6.3

  • Why does it NOT give a segmentation violation?

    - by user198729
    The code below is said to give a segmentation violation: #include <stdio.h> #include <string.h> void function(char *str) { char buffer[16]; strcpy(buffer,str); } int main() { char large_string[256]; int i; for( i = 0; i < 255; i++) large_string[i] = 'A'; function(large_string); return 1; } It's compiled and run like this: gcc -Wall -Wextra hw.cpp && a.exe But there is nothing output. NOTE The above code indeed overwrites the ret address and so on if you really understand what's going underneath.

  • Tortoise SVN does not give option to "Add to SVN"

    - by Clay Nichols
    I've created an SVN repository and added folders and added contents and Committed. No problem. But when go to add a new folder (the others were on the P:\ drive, now I want to add our website which is on the C:\ drive) but Tortoise doesn't give me the option of Adding a folder. I have no idea why. Help file shows the instructions I'd expect ("right click on the folder you want to add and choose +Add...") but Add... isn't in the menu. This is TortoiseSVN v 1.6.7.18415 (I'm about to update it but I was able to add folders before so I don't think this is just a bug, I think maybe I'm missing something obvious).

  • Why does this give a segmentation fault?

    - by nightcracker
    I'm stunned, why does this code give me a segmentation fault? #include <stdio.h> #define LIMIT 1500000 typedef struct { int p; int a; int b; } triplet; int main(int argc, char **argv) { int i; triplet triplets[LIMIT]; for (i = 0; i < 5; i++) { triplets[i].p = 9; // remove this line and everything works fine } printf("%d\n", triplets[15].p); return 0; } EDIT: After changing LIMIT to 150 I no longer get a segmentation fault, it prints random numbers instead.

  • All sites give Error 500 under Sharepoint Foundation (SP2010)

    - by MarkH
    I've just installed Sharepoint Foundatuion on my W2008 64bit server and got it up and running as far as being able to access the Central Admin etc just fine. I did have to disable 32 bit apps in the application pools for all the SP sites and also, following a tip on here, add a config option for bitness64 as a prerequisite for the services. However whenever I try to access the "Sharepoint - 80" site itself (or another site collection I created in the admin tool), I am getting an unhelpful 500 error. The log doesn't add anything - I can't find anything to give me a clue as to what it's complaining about. The server is a hosted VPS and all services like SQL are running locally (and are OK). Any ideas where I look next? M

  • Give users permissions on item in other list

    - by Nomz
    Hello everyone, This is what im working on: i have two lists, first one: collumn user and collumn project that the user is assigend to. second one (library): a list of all the projects I was wondering, how, by every row that is created in the first list (so adding a user and a project) it is possible to grant the user permissions on this project's reference in the second library (the projects library). Example: ProjectLibrary: Project1 Project2 Project3 the first list: user1 project1 user1 project2 user2 project2 user2 project3 user3 project3 now i want to give each user permission to see the project he's assigned to so that when he opens a third form, a combobox filled with projects will only show the projects he has permissions on. thank you so much!

  • Oracle curcular join sometimes give duplicates, but sometimes does not

    - by Kaushik
    By mistake I wrote a query like this: select * from a,b,c where a.col=b.col and b.col2=c.col2 and c.col3=a.col4 So there is a circular join here. Now the thing is sometimes this query returns duplicate result, sometimes it returns unique(correct) results. I am trying to understand why it does not give duplicate results always. Also if circular joins are not allowed, how come Oracle does not throw an error. EDIT: This is the actual query. After reading ti carefully, I am not sure anymore if this is a circular join or not.It does not seem so...but why I get duplicates only sometime? select * from a,b,c,d where a.col=b.col and b.col=c.col and c.col2=d.col2 and d.col2 =a.col2

  • Why do I have to give an identifier?

    - by Knowing me knowing you
    In code: try { System.out.print(fromClient.readLine()); } catch(IOException )//LINE 1 { System.err.println("Error while trying to read from Client"); } In code line marked as LINE 1 compiler forces me to give an identifier even though I'm not using it. Why this unnatural constrain? And then if I type an identifier I'm getting warning that identifier isn't used. It just doesn't make sense to me, forcing a programmer to do something unnecesarry and surplus. And after me someone will revise this code and will be wondering if I didn't use this variable on purpouse or I just forgot. So in order to avoid that I have to write additional comment explaining why I do not use variable which is unnecessary in my code. Thanks

  • How can I give a color to imagecolorallocate?

    - by Roman
    I have a PHP variable which contains information about color. For example $text_color = "ff90f3". Now I want to give this color to imagecolorallocate. The imagecolorallocate works like that: imagecolorallocate($im, 0xFF, 0xFF, 0xFF); So, I am trying to do the following: $r_bg = bin2hex("0x".substr($text_color,0,2)); $g_bg = bin2hex("0x".substr($text_color,2,2)); $b_bg = bin2hex("0x".substr($text_color,4,2)); $bg_col = imagecolorallocate($image, $r_bg, $g_bg, $b_bg); It does not work. Why? I try it also without bin2hex, it also did not work. Can anybody help me with that?

  • Python: Give a class its own `self` at instantiation time

    - by SuperDisk
    I've got a button class that you can instantiate like so: engine.createElement((0, 0), Button(code=print, args=("Stuff!",))) And when it is clicked it will print "Stuff!". However, I need the button to destroy itself whenever it is clicked. Something like this: engine.createElement((0, 0), Button(code=engine.killElement, args=(self,))) However, that would just kill the caller, because self refers to the caller at that moment. What I need to do is give the class its own 'self' in advance... I thought of just making the string 'self' refer to the self variable upon click, but what if I wanted to use the string 'self' in the arguments? What is the way to do this? Is my architecture all wrong or something? Thanks.

  • @ContextConfiguration in Spring 3.0 give me No default constructor found

    - by atomsfat
    I have already do the test using AbstractDependencyInjectionSpringContextTests and it works but in spring 3 it is deprecated, so I decided to try @ContextConfiguration but spring say that default constructor is not found, I check and the class doesn't have any constructor.

  • Give WPF design mode default objects

    - by Janko R
    In my application I have <Rectangle.Margin> <MultiBinding Converter="{StaticResource XYPosToThicknessConverter}"> <Binding Path="XPos"/> <Binding Path="YPos"/> </MultiBinding> </Rectangle.Margin> The Data Context is set during runtime. The application works, but the design window in VS does not show a preview but System.InvalidCastException. That’s why I added a default object in the XYPosToThicknessConverter which is ugly. class XYPosToThicknessConverter : IMultiValueConverter { public object Convert(object[] values, Type targetType, object parameter, System.Globalization.CultureInfo culture) { // stupid check to give the design window its default object. if (!(values[0] is IConvertible)) return new System.Windows.Thickness(3, 3, 0, 0); // useful code and exception throwing starts here // ... } } My Questions: What does VS/the process that builds the design window pass to XYPosToThicknessConverter and what is way to find it out by myself. How do I change my XAML code, so that the design window gets its default object and is this the best way to handle this problem? I’m using VS2010RC with Net4.0

  • Give back full control to a user on a disk from another computer

    - by Foghorn
    I have my friend's hard drive mounted externally. After messing with the permissions with TAKEOWN so I could fix some viruses, I have full control over their drive. The problem is, now it's stuck in a "autochk not found" reboot sequence. I think the problem is that the boot sector is invisible to the drive now. So my question is, How can I use icacls to give back the full ownership, when the user I am giving it to is not on my machine? I ran the TAKEOWN command from my windows 7 laptop, their machine is a windows xp Professional with three partitions, I only altered the one that has the boot sector. Here is the permissions that icacls shows: (Where my computer is %System% my username is ME, and the drive is E:\ C:\Users\ME icacls E:\* E:\$RECYCLE.BIN %System%\ME:(OI)(CI)(F) Mandatory Label\Low Mandatory Level:(OI)(CI)(IO)(NW) E:\ALLDATAW %System%\ME:(I)(OI)(CI)(F) E:\alrt_200.data %System%\ME:(OI)(CI)(F) E:\AUTOEXEC.BAT %System%\ME:(OI)(CI)(F) E:\AZ Commercial %System%\ME:(I)(OI)(CI)(F) E:\boot.ini %System%\ME:(OI)(CI)(F) E:\Config.Msi %System%\ME:(I)(OI)(CI)(F) E:\CONFIG.SYS %System%\ME:(OI)(CI)(F) E:\Documents and Settings %System%\ME:(I)(OI)(CI)(F) E:\IO.SYS %System%\ME:(OI)(CI)(F) E:\Mitchell1 %System%\ME:(I)(OI)(CI)(F) E:\MSDOS.SYS %System%\ME:(OI)(CI)(F) E:\MSOCache %System%\ME:(I)(OI)(CI)(F) E:\NTDClient.log %System%\ME:(OI)(CI)(F) E:\NTDETECT.COM %System%\ME:(OI)(CI)(F) E:\ntldr %System%\ME:(OI)(CI)(F) E:\pagefile.sys %System%\ME:(OI)(CI)(F) E:\Program Files %System%\ME:(I)(OI)(CI)(F) E:\RECYCLER %System%\ME:(I)(OI)(CI)(F) E:\RHDSetup.log %System%\ME:(OI)(CI)(F) E:\System Volume Information %System%\ME:(I)(OI)(CI)(F) E:\WINDOWS %System%\ME:(I)(OI)(CI)(F) Successfully processed 22 files; Failed processing 0 files C:\Users\ME
