• How can I achive this effect jQuery? or can it be done with CSS?

  - by Charles Marsh

  Hello All, Is it possible to switch HTML on click? I have an index page with a large image on the front. Under the image there is four links. When the cursor rolls over the link I would like a small tool tip to appear. Then when the clicks the link I want the large Image to change and some extra HTML to appear over it. (just a small content box) The tooltip I think I have sorted using Jquery but I'm not sure how I can change the image [b]AND[/b] add a small content box over the image. Thanks in advanced everyone.

• Figuring out what makes a C++ class abstract in VS2008

  - by suszterpatt

  I'm using VS2008 to build a plain old C++ program (not C++/CLI). I have an abstract base class and a non-abstract derived class, and building this: Base* obj; obj = new Derived(); fails with the error "'Derived': cannot instantiate abstract class". (It may be worth noting, however, that if I hover over Base with the cursor, VS will pop up a tooltip saying "class Base abstract", but hovering over Derived will only say "class Derived" (no "abstract")). The definitions of these classes are fairly large and I'd like to avoid manually checking if each method has been overridden. Can VS do this for me somehow? Any general tips on pinpointing the exact parts of the class' definition that make it abstract?

• How can I tell if an ADODB::_RecordsetPtr has already been created?

  - by scottm

  I am trying to write a class that uses ADO to retrieve SQL records. The intent is for the class to maintain one private recordset an other methods move forward, retrieve fields, etc. This is a basic example of my class: class SqlADO { private: ADODB::_RecordsetPtr m_recordset; public: void Open(); //open the connection void Execute(const char* sql); // creates or replaces current recordset void Next(); //moves recordset cursor forward void Field(const char* fieldName); //retrieves field name from current record of the recordset }; My Questions: In the Execute method, how can I check to see that the recordset instance has been created (or do I need to) so that I can close it first? Do you know of any good ADO COM Interop references?

• Is INT the correct datatype for ABS(CHECKSUM(NEWID()))?

  - by Chad Sellers

  I'm in the process of creating unique customers ID's that is an alternative Id for external use. In the process of adding a new column "cust_uid" with datatype INT for my unique ID's, When I do an INSERT into this new column: Insert Into Customers(cust_uid) Select ABS(CHECKSUM(NEWID())) I get a error: Could not create an acceptable cursor. OLE DB provider "SQLNCLI" for linked server "SHQ2IIS1" returned message "Multiple-step OLE DB operation generated errors. Check each OLE DB status value, if available. No work was done. I've check all data types on both tables and the only things that has changed is the new column in both tables. The update is being done on one Big @$$ table...and for reasons above my pay grade, we would like to have new uid's that are different form the one's that we currently have "so users don't know how many accounts we actually have." Is INT the correct datatype for ABS(CHECKSUM(NEWID())) ?

• Use concat and maintain length of variable

  - by user1682055

  I'm trying to use concat on some variables. These variables have been declared as chars: declare v_order_date char(10); declare v_quantity char(11); declare v_plant char(100); I have a cursor where I am setting these as some outputs. To call the results, I am setting v_msg as set v_msg := concat( v_msg, '\n', v_order_date, v_quantity, v_plant); However, the result I am getting when I select v_msg is: 2012-01-222501008 Creeping Buttercup but I want to maintain the length of the declared variables in my select that looks like this 2012-01-22 250 1008 Creeping Buttercup Are there any suggestions? Thank you.

• hierarchical data from self referencing table in tree form

  - by Beta033

  It looks like this has been asked and answered in all the simple cases, excluding the one that I'm having trouble with. I've tried using a recursive CTE to generate this; however maybe a cursor would be better? Or maybe a set of recursive functions will do the trick? Can this be done in a cte? consider the following table PrimaryKey ParentKey 1 NULL 2 1 3 6 4 7 5 2 6 1 7 NULL should yield PK 1 -2 --5 -6 --3 7 -4 where the number of - marks equal the depth, my primary difficulty is the ordering.

• Using Linq, how to separate a list in to grouped objects by name?

  - by Dr. Zim

  I have a table where a record looks like this varchar(255) Name varchar(255) Text varchar(255) Value Name is the DDL name, Text is what is displayed, and Value is returned upon selection. There are between one and twenty options for each Name. Without iterating though each option like a cursor, is there any way to pull out a list of objects, one for each unique DDL Name, using Linq and C#? A sample of the data: Beds '4 (10)' 4 Beds '5 (1)' 5 Beds '7 (1)' 7 Baths 'NA (13)' NULL Baths '0 (1)' 0 Baths '1 (13)' 1 I was thinking about doing an outer select to get the unique Names, then an inner select to get the list of options for it, then return the set as a List of a set of Lists.

• MVC Html.DropDownList closes prematurely in IE7

  - by Jon

  I'm using ASP.NET MVC with jquery. I have a couple of dropdownlists. When I select one via mouse click and then scroll down over the items using the mouse/cursor, the list closes before a selection can be made, before the mouse can be clicked. This doesn't happen when I open them and then up/down arrow to select an item. It doesn't happen all of the time, but a lot. Just to try something different, I added a jquery "select" control with hardcoded values (options) and it displays the same behavior. Any ideas? <%: Html.DropDownList("Accounts", (IEnumerable)ViewData["Accounts"], "-- Select an account --")% Thank you

• Does Visual Studio 2010 on x64 crash often? Or is it just on my PC?

  - by JK

  MY VS2010 crashes dozens of times a day. Compare that to 2008 and 2005 which were rock solid. Is 2010 known to be susceptible to crashing? Or could it be my environment? I'm using x64 as a dev box for the first time. The only plugin I has so far is Ankh. It crashes when doing different things. One I've noticed so far that always happens is if I press the key sequence alt-f-s-up (or any cursor key) it will crash every time.

• Alternate to control+drag to connect view element with file owner in xCode interface builder?

  - by yldave

  Working on an iPhone application through a TightVNC connection into a Mac Mini; the control+drag operation in Interface Builder to connect a view element to file owner doesn't work - I don't see the connecting line. It does work when I connect keyboard, mouse and monitor to the Mini and work on it directly, however it is a lot more convenient for me to run it through a VNC connection. Must be some quirk of the TightVNC connection that is preventing this. I tried different TightVNC settings for the cursor (let server handle it and so on) but no luck. Is there an alternative to control+drag to hook up outlets?

• Mimic Sublime Text multiselect in Notepad++ using autohotkey

  - by capnhud

  In sublime text 2 you can multi select(cursor) lines by holding ctrl+alt+arrow key (up/down). In notepad++ you can accomplish the same thing by holding ctrl and clicking the additional lines(areas) you would like to edit. I figured I could use a autohotkey script to accomplish the same functionality. So I tried #IfWinActive, ahk_class Notepad++ ^!Down::^Click but each time that I try to load the script I get Error at Line 2 Line Text: ^Click Error: This line does not contain a recognized action the program will exit then I tried #IfWinActive, ahk_class Notepad++ ^!Down::send ^Click but that shows up as ETXClick in notepad++ What more do I need to get this script to work only for Notepad++

• MySQL: How to consume/discard the result of a query?

  - by GetFree

  I have a stored procedure which executes an optimize table statement for every table in a DB. Those optimize table statements are prepared statements of course (they have to be built at runtime) and I need to call that procedure from PHP using ext/mysql API. Unfortunately, ext/mysql does't support doing such thing because optimize table returns a result set and in order to handle that, the new mysql protocol is required, which is supported by the "new" ext/mysqli API. Well... there are several things I dont have control over, so it's not in my posibilities to upgrade to ext/mysqli any time soon, nor can I implement the procedure as PHP code rather than sql code. So I thought if it would be possible somehow to consume/discard the result of optimize table inside the stored procedure so that ext/mysql doesn't complain about it. One thing to consider is that since the optimize table statements are prepared statements, you can't use a cursor over them.

• Contacts activity doesn't return data

  - by Mike

  In my app I simply open the list of activities and when a contact is clicked I attempt to retrieve the name of the contact selected and put it into a string. The app crashes in the onActivityResult() function. I do have the READ_CONTACTS permission set. /** * Opens the contacts activity */ public void openContacts() { Intent intent = new Intent(Intent.ACTION_PICK, People.CONTENT_URI); startActivityForResult(intent, PICK_CONTACT); } @Override public void onActivityResult(int reqCode, int resultCode, Intent data) { super.onActivityResult(reqCode, resultCode, data); switch (reqCode) { case (PICK_CONTACT) : if (resultCode == Activity.RESULT_OK) { Uri contactData = data.getData(); Cursor c = managedQuery(contactData, null, null, null, null); //NullPointerException thrown here, line 102 if (c.moveToFirst()) { String name = c.getString(c.getColumnIndexOrThrow(People.NAME)); FRIEND_NAME = name; showConfirmDialog(name); } } break; } } The following logcat error logs are returned: Any help is appreciated.

• Dynamically generated controls issue.

  - by Thomas

  I have a form with a panel docked in it. I then dynamically create 15 panels (named: panel_n) and 15 pictureboxes (named: picturebox_n) on the primary panel (named ContainerPanel). When dragging the any picturebox over a panel (panel_n) created using the relevant mouse events. I would like to get the panel's name that the picture box was dragged over. The mouse cursor seems to be captured. I have tried creating a IMessageFilter interface, but there are still no events that trigger when dragging one of the pictureboxes over any one of the panels. The ClientRectangle.IntersectsWith function also does not work as the co-ords are always 0,0. All I need is the panel name where the picturebox was dragged over (preferably on the mouseup event)

• [C#] Creating standalone, console (shell) for domain-specific operations

  - by mr.b

  Say that I have a system service, and I want to offer a low-level maintenance access to it. For that purpose, I'd like to create a standalone, console application that somehow connects to server process and lets user type in commands, allow it to use auto-completion and auto-suggestion on single/double TAB press (just like linux bash shell, mysql cli, cmd.exe, and countless others), allow command line editing capabilities (history, cursor keys to move around text..), etc. Now, it's not that much of a problem to create something like that by rolling my own from scratch, handling user input, scanning pressed keys, and doing correct actions. But, why reinvent the wheel? Is there some library/framework that helps with this kind of problems, just like readline library that offers improved command-line editing capabilities under linux? Of course, this new "shell" would respond only to valid, domain-specific commands, and would suggest valid arguments, options, switches... Any ideas? Thanks!

• Firefox 3.03 and contentEditable

  - by Ash

  I'm using the contentEditable attribute on a DIV element in Firefox 3.03. Setting it to true allows me to edit the text content of the DIV, as expected. Then, when I set contentEditable to "false", the div is no longer editable, also as expected. However the flashing caret (text input cursor) remains visible even though the text is no longer editable. The caret is now also visible when I click on most other text in the same page, even in normal text paragraphs. Has anyone seen this before? Is there any way to force the caret hidden? (When I either resize the browser or click within another application, and come back, the caret magically disappears.)

• why is the address bar black in Google chrome so you cannot see what you're typing ? [closed]

  - by Tim

  The address bar background color in Google Chrome is black. I cannot see what I'm typing. What's going on? This is a problem when you're typing in a URL you've never used before (so there's no matching history). Type in a URL you've never used before. Imagine someone is giving it to you over the phone. Make a typo somewhere. Use the back arrow to go back and correct it. You cannot see where the cursor is. This just started happening yesterday. I'm on WinXP Pro.
