• How do I add line-height to a <select> using jQuery?

  - by Rohan

  I have a element <select name="dropdown" id="dropdown"> <option>Option 1</option> <option>Option 2</option> <option>Option 3</option> <option>Option 4</option> </select> Now if I add a CSS line-height property to the dropdown, it doesn't work. How would I use jQuery to style this? I prefer not to use plugins, because this is the only styling I wish to apply.

Click one of the images to see what I mean. the dialog that pops up should be over the image you clicked.

• ParentViewController returns nil

  - by Andreas Johannessen

  Hi I know there are many questions on this, but I don't get it to work. I present a UITabBarController with the presentModalViewController. However when I try to get title from the navigationItem title attribute in the UINavigationController class that presents the tabcontroller, it returns nil no matter what I do. I have the NSLog in the viewDidLoad method in tabcontroller class. I also cast the UIViewController which is returned by the self.parentViewController property. Then I try to access the title through: NSLog(@"%@", castedViewController.navigationItem.title); Any suggestions?

• Assigning function within function object without invoking the function itself.

  - by webzide

  Dear experts, I am trying to assign an function within an function object property without actually invoking then function itself. for instance, I have the following function object class definition function objectOne(name, value, id){ this.name=name; this.value=value; this.id=id; this.methodOne=methodFunction(this); } the last line this.methodOne=methodFunction(this); I want to pass the current object to the function but at the same time i don't want to execute the function right now. But if I do it this way without the bracket this.methodOne=methodFunction then the argument of this object would not be passed as a parameter to the function. Is there a way to work through this. Thank you in advance

• How to select the range for pasting using vba

  - by user1616384

  I wrote some code for selecting the particular row and pasting it in column wise using paste-special property. It is working correctly my code is : lngRow = Me.TextBox4.Value strCol = Me.TextBox5.Value Set rng = Range("A:A").Find(What:=lngRow, LookIn:=xlValues, LookAt:=xlWhole) If rng Is Nothing Then MsgBox "Value not found in row 1", vbExclamation Else Range(rng, rng.End(xlToRight)).Copy Range("A1:E3").Columns(strCol).Offset(, 1).PasteSpecial Transpose:=True Range("A1:E3").Rows(1).Copy Range("A1:E3").Columns(strCol).PasteSpecial Transpose:=True endif the problem here is I am using Range(rng, rng.End(xlToRight)).Copy to copy the values and for pasting I am using Range("A1:E3").Columns(strCol).Offset(, 1).PasteSpecial Transpose:=True. How can I paste all the values which are copied? Because if the values are in column F then this macro will not paste those values.

• Is this the correct why of speaking to a "Content Manager" Class?

  - by DeanMc

  I am creating a silverlight site. I am currently breaking out my ideas into pieces of functionality. One of the idea's I have is the concept of a content manager. This is essentially a UI control with 4 regions. Top, Bottom, Right & Left. I also have a collection of objects that are considered "Menu Items". These are controls that function as a way to navigate around, similar to links. The idea I have is to implement an IMenuItem interface. Among the standard pieces of information (Text, PageReference, etc) I was also going to hold a reference to the content manager. My idea behind this thinking is that I can pass the PageReference to a property on the ContentManager and then call a method which knows how to update the content manager accordingly. Is this the best way of implementing this or is their some sort of pattern for it?

• how to create a auto-incremented attribute in xcode managed object model

  - by Mausimo

  Hey, what i want to do is to make a int that will be the ID of the entity and auto increment itself whenever a new entity is added (just like a SQL identity property). Is this possible? i tried using indexed (checked on attribute) however there is no description to what indexed even does. EDIT: I am adding annotations to a map, when you click the pin the annotationview with a chevron shows up. Now when you click this button i would like to load an associated picture. However the only way i know how to link the picture to this button is to give the picture a unique id, and then set the button.tag to this id and then load based on the button.tag.

• Mixing LINQ to SQL with properties of objects in a generic list

  - by BPotocki

  I am trying to accomplish something like this query: var query = from a in DatabaseTable where listOfObjects.Any(x => x.Id == a.Id) select a; Basically, I want to filter the results where a.Id equals a property of one of the objects in the generic list "listOfObjects". I'm getting the error "Local sequence cannot be used in LINQ to SQL implementation of query operators except the Contains() operator." Any ideas on how to filter this in an easily readable way using "contains" or another method? Thanks in advance.

• How to close a form in UserControl

  - by FJPoort

  I created a UserControl with the buttons Save, Close and Cancel. I want to close the form without saving on the Cancel button, prompt a message to save on the Close button and Save without closing on the Save button. Normally, I would have used this.Close() on the Cancel button, but the UserControl doesn't have such an option. So I guess I have to set a property for that. Scrolling down the "Questions that may already have your answer" section, I came across this question: How to close a ChildWindow from an UserControl button loaded inside it? I used the following C# code: private void btnCancel_Click(object sender, EventArgs e) { ProjectInfo infoScreen = (ProjectInfo)this.Parent; infoScreen.Close(); } This does the job for one screen, but I wonder if I have to apply this code for all the screen I have? I think there should be a more efficient way. So my question is: Do I need to apply this code for every form I have, or is there another (more efficient) way?

• How to map it? HasOne x References

  - by Felipe

  Hi everyones, I need to make a mapping One by One, and I have some doubts. I have this classes: public class DocumentType { public virtual int Id { get; set; } /* othes properties for documenttype */ public virtual DocumentConfiguration Configuration { get; set; } public DocumentType () { } } public class DocumentConfiguration { public virtual int Id { get; set; } /* some other properties for configuration */ public virtual DocumentType Type { get; set; } public DocumentConfiguration () { } } A DocumentType object has only one DocumentConfiguration, but it is not a inherits, it's only one by one and unique, to separate properties. How should be my mappings in this case ? Should I use References or HasOne ? Someone could give an example ? When I load a DocumentType object I'd like to auto load the property Configuration (in documentType). Thanks a lot guys! Cheers

• How do I mount a virtual filesystem in a folder?

  - by chacham15

  I implemented a virtual filesystem using Dokan. I tried to set the drive letter to C but it errors every time. I was wondering if there is a different virtual filesystem which will allow me to do that or if there is a way of fixing it. Is there some windows api call which will allow me to remount the filesystem in a folder? Thanks!!! EDIT: The windows manager does not list the virtual drive, so I cannot mount it through the usual Windows interface. Also, I tried to change the drive name through the property interface and it wouldnt let me do that either.

• Change UIView alpha value

  - by Ask

  I'm trying to create an UIView and change its alpha property to simulate backlight change. Here is my code if (TransparentView == nil) { TransparentView = [[UIView alloc] initWithFrame:self.view.bounds]; TransparentView.backgroundColor = [UIColor whiteColor]; self.view = TransparentView; } start=start+appDelegate.OnOffTime; TransparentView.alpha = 0.2; float step = 1.0 / ( appDelegate.OnOffTime * 100); for (float f = 0; f < 1; f=f+step) { TransparentView.alpha = (CGFloat)(1 - f); [NSThread sleepForTimeInterval:0.01]; } Both TransparentView.alpha = 0.2 and TransparentView.alpha = (CGFloat)(1 - f) do change TransparentView.alpha, but only TransparentView.alpha = 0.2 changes real device "brightness'. What am I doing wrong?

• DataGridView that always has one row selected

  - by Dan Neely

  I'm using a DGV to show a list of images with text captions as a picklist. Their must always be a one and only one selection made in the list. I can't find a way to prevent the user from clearing the selection with a control-click on the selected row. Is there a property in the designer I'm missing that could do this? If I have to override the behavior in the mouse click events are there other ways the user could clear the current selection that need covered as well? Is there a third approach I could take that's less cumbersome than my second idea?

• Vertical positioning of text in table cell

  - by Robert

  When I place an image followed by text in a table cell, the vertical alignment of the text shifts down compared to text in adjacent cells. I tried using a line-height CSS property, but it didn't seem to have an affect. In the following example, I need "123 Description" to be flush with "cell one." Also, there is a space between the image and "123" by default. How can I adjust that - negative margins perhaps? <html <head <style type="text/css" table { border-collapse: collapse; } td { border: thin solid; width: 10em;} /* .adjust-text { line-height: 1.3em; } */ </style </head <body <table <tbody <tr <tdcell one</td <td <img src="small-star.png" / <span class="adjust-text"123 Description</span </td </tr </tbody </table </body </html

• jquery, simplemodal with a tooltip?

  - by matthewsteiner

  I'm using http://dev.mariusilie.net/content/simple-tooltip-jquery-plugin for my tooltip and simple modal for a modal window. I've got a link in the modal window and when I put my mouse over it, the tooltip is there, but it's beneath the modal window. I think it has to do with "z-index". I looked and I think the modal window is at 1000. I've set the #simpleTooltip property in the css with various z-index values, with no luck. It always appears beneath the modal window. Any Ideas?

• Extend Google AppEngine User in JRuby?

  I'm working with JRuby and DataMapper running on Google AppEngine. I want to add a property to the AppEngine::User like :active_calendar which is a reference to a Calendar kind. I was able to do something in Python this way using a back reference. Are these possible in JRuby? Is this possible? Do I need to subclass the User? Can I even do that? If so - how? Thanks!

• Deserializing only select properties of an Entity using JDOQL query string?

  - by user246114

  Hi, I have a rather large class stored in the datastore, for example a User class with lots of fields (I'm using java, omitting all decorations below example for clarity): @PersistenceCapable class User { private String username; private String city; private String state; private String country; private String favColor; } For some user queries, I only need the favColor property, but right now I'm doing this: SELECT FROM " + User.class.getName() + " WHERE username == 'bob' which should deserialize all of the entity properties. Is it possible to do something instead like: SELECT username, favColor FROM " + User.class.getName() + " WHERE username == 'bob' and then in this case, all of the returned User instances will only spend time deserializing the username and favColor properties, and not the city/state/country properties? If so, then I suppose all the other properties will be null (in the case of objects) or 0 for int/long/float? Thank you

• switching between one and two displays in visual studio

  - by WebDude

  Most of the time I work Visual Studio with two monitors. I setup my Visual Studio to sit nicely across both monitors with code on the one side and property windows etc. on the other. However, occasionally I need to remove into my work station from home where I only have one monitor. What ends up happening is I have to re-setup my entire workspace to be used on one monitor, and when I get back to my work station I have to undo this again to get to my optimal 2 monitor environment. Is there a way to save some set layouts in Visual Studio so I could quickly switch back and forward? Example: One Monitor Layout versus Two Monito Layout?

• Detect at runtime which country's App Store my iPhone app was downloaded from?

  - by Mike McMaster

  I have a feature in my iPhone application that, for business reasons, should only be shown/available to customers in the US. If I want to release this app to App Stores outside the US, what's the best way to figure out which country I'm in without relying on user-defined settings such as language and locale? In my mind, the ideal solution is that there's some runtime property that can tell me which App Store country the app was downloaded from, and I can take action accordingly. Looking through the docs and searching the web, I'm not coming up with anything in this department. I don't expect the solution to be 100% foolproof as far as users not being in the country they say they're from, but as close as possible would be nice. I suppose one solution would be to make a separate build for a new product on the App Store and have two versions, one for the US and one for the others, but that doesn't seem ideal. I'm hoping it can be the same product on the App Store to prevent things like fragmentation of user reviews. Thanks in advance!

  I want all my views to inherit from a baseview data so I can set some shared properties that all my views will need. Can I set some properties in OnExecuting so I don't have to do it for all Actions? I want to then display the string value of the property in all my view pages. If yes, how can I do this? I need to hook into the base view data somehow? so i'll have: public MyViewData : ViewData { } And I need one for generics also?
