  • JavaScript: A BackSlash as part of the string

    - by Abs
    Hello all, I have a JavaScript variable that I echo out using PHP which is shown like this in the page source: var db_1 = 'C:\this\path'; When I set the value of a text field with that variable like so: $('#myinput').val(db_1); The slashes have disappeared and only the other characters are left! Why is this and how can I put the slashes back in?? Thanks all

  • settings file vs app.config

    - by fearofawhackplanet
    I'm not really understanding the interaction/differences between settings and config files. If I add an entry to the settings file, it gets added to the app.config as well. Does this mean that changing the value in the app.config will update the settings? If not, how do I update settings in a live application? What's the general purpose of using a settings file instead of putting things directly in app.config?

  • How to implement event listener in background of the main program in java?

    - by Johny
    Hi im a beginner so sorry for my question if it sounds naive. I want to implement a thread that runs in the background and listens all the time. By listening i mean, say it keeps check on a value returned from main thread and if the vaue exceeds certain figure, it executes some method, or say exits the program. If you could give me some idea or at least refer me to something useful, that'll be great.

  • Table in DB for generating primary keys?

    - by Sapphire
    Do you ever use a separate table for "generating" artificial primary keys for DB (and why)? What I mean is to have a table with two columns, table name and current ID - with which you could get new "ID" for some table by simply locking the row with that table name, getting the current value of the key, increment it by one, and unlock the row. Why would you prefer this over standard integer identity column? P.S. The "idea" is from Fowlers Patterns of Enterprise Application Architecture, btw...

  • Why are member constants available even if there are no instances of a its class?

    - by flockofcode
    1) Why are member constants available even if there are no instances of a its class? 2) Is the only reason why constant expressions need to be fully evaluated at compile time due to compiler replacing constant variable with literal value? 3) Since string is also an object, I would think the following would produce an error, but it doesn’t. Why? class A { const string b = “it works”; } thank you

  • Margin 0 and fixed background cause weird border OR what?

    - by alumi
    I am currently developing this site: tochat.vn As viewing in Firefox 7.0.1, it has annoying white border at top of the page. I have been trying to remove the border in many ways, but nothing really works. Actually, there are 2 things I noticed, when I removed "margin: 0" on body tag (on reset.css) OR when I removed the "fixed" value of background-attachment of the "body" class (on style.css) the border disappeared. But I can't remove these attributes :( Any suggestion?

  • How do I set the text color of a Cocoa tooltip?

    - by Adam Preble
    I am using BGHUDAppKit for an outline view within a HUD-style (black) NSPanel. As such the text in my outline view cells is light gray or white. Unfortunately this means that when I hover to bring up a tooltip for a cell's value, it shows up as light gray text on yellow, which is illegible. How can I set the text color for the tooltip, or is there a way that I can modify the control itself (without changing its appearance) to work better with the tooltip mechanism?

  • My store returns no code id and breaks 404 error. Magento

    - by numerical25
    I know what the issue is but I dont know how to fix it. I just migrated my magento store locally and I guess possibly some data may have been lost when transferring the DB. the DB is very large. Anyhow, when I login to my admin page, I get a 404 error, page was not found. I debugged the issue and got down to the wire. The exception is thrown in Mage/Core/Model/App.php. Line 759 to be exacted. The following is a snippet. Mage/Core/Model/App.php if (empty($this->_stores[$id])) { $store = Mage::getModel('core/store'); /* @var $store Mage_Core_Model_Store */ if (is_numeric($id)) { $store->load($id); // THIS ID IS FROM Mage_Core_Model_App::ADMIN_STORE_ID and its empty which causes the error } elseif (is_string($id)) { $store->load($id, 'code'); } if (!$store->getCode()) { // RETURNS FALSE HERE BECAUSE NO ID Specified $this->throwStoreException(); } $this->_stores[$store->getStoreId()] = $store; $this->_stores[$store->getCode()] = $store; } The store returns null because $id is null so it therefore does not load any model which explains why it returns false when calling getCode() [EDIT] If you want clarification, please ask for more before voting my post down. Remember I am still trying to get help not get neglected. I am using Version 1.4.1.1. When I type in the URL for admin, I get a 404 page. I walked through the code thouroughly and found that the Model MAGE_CORE_MODEL_STORE::getCode(); Returns Null which triggers the exception. and ends the script. I do not have any other detail. I further troubleshooted the issue by checking the database and that is what the screen shot is. Showing that there is infact data in the Code Colunn. So my question is why is the Model returning a empty column when the column clearly has a value. What can I do to further troubleshoot and figure out why its not working [EDIT UPDATE NEW] I did some research. the reason its returning NULL is because the store ID is null being passed Mage::getStoreConfigFlag('web/secure/use_in_adminhtml', Mage_Core_Model_App::ADMIN_STORE_ID); // THIS IS THE ID being specified Mage_Core_Model_App::ADMIN_STORE_ID has no value in it, so this method throws the exception. Not sure why how to fix this.

    - by Vikas
    Hi, Can we use foreach loop for Iqueryable object? I'd like to do something as follow: query = Iqueryable<Myclass> = objDataContext.Myclass; // objDataContext is an object of LINQ datacontext class int[] arr1 = new int[] { 3, 4, 5 }; foreach (int i in arr1) { query = query.Where(q => (q.f_id1 == i || q.f_id2 == i || q.f_id3 == i)); } It gives me wrong output as each time value if i is changed.

  • Minimize the sequence by putting appropriate operations ' DP'

    - by Vikas
    Given a sequence,say, 222 We have to put a '+' or '* ' between each adjacent pair. '* ' has higher precedence over '+' We have to o/p the string whose evaluation leads to minimum value. O/p must be lexicographically smallest if there are more than one. inp:222 o/p: 2*2+2 Explaination: 2+2+2=6 2+2*2=6 2*2+2=6 of this 3rd is lexicographically smallest. I was wondering how to construct a DP solution for this.
