• Google App Engine - Is os.environ reset between requests?

  - by Ian Charnas

  Hello I can't think of a way to test this and was hoping someone here knew the answer... I'm storing some request-specific data in os.environ, and was wondering if that data was going to leak to other requests. Does anyone know? Yes I realize that it's normal to use request.environ for this, and usually I do, but I want to store the currently authorized user ID (I'm using custom auth, not GAE auth) inside os.environ so that the models know the currently logged in user (remember, they don't have access to request.environ) without me having to pass the request object to just about every single model method. any help would be greatly appreciated Ian

• jQuery UI Themes

  - by Theopile

  So I downloaded a jQuery UI Theme and link it, but it looks nothing like the them on the site. The buttons are huge and so is the text. <link rel="stylesheet" type="text/css" href="/css/trontastic/jquery-ui-1.8.2.custom.css"> $('#Delete').dialog({ modal: true, autoOpen: false, title: "Delete?", buttons: { "Yes": function(){ $(this).dialog('close'); $('li#'+$id).remove(); $('.nav').sortUpdate(); }, "No":function(){ $(this).dialog('close'); } }, draggable: false, resizable: false }); Am I missing something or is there addition css that I have to handcode? Thanks

• Window scrolling up when jquery dialog opens up

  - by zoom_pat277

  I am trying to open a modal jquery dialog using jquery 1.4 and jquery-ui-1.8rc3.custom.js The dialog opens up with no issues, in all browsers, but in IE 7 and 6, after the dialog opens up, the window scrolls itself to the buttom... I tried scrolling the window up back to the modal position but is very inconsistent. was using the following line of code after opening up the modal window.scrollTo($('selector').dialog('option', 'position')[0],$('selector').dialog('option', 'position')[1]); One weird thing I am noticing is that after I open the modal, the page becomes huge... as if some extra things adds up on the bottom .... and it eventually scrolls to the bottom. Any idea why this could be hapenning in html <div id="selector"> </div> in document.ready $('#selector').dialog({ bgiframe: true, autoOpen: false, width: 100, height: 100, modal: true, position: 'top' }); in js $('#selector').dialog('open');

• WPF: Best method for printing paginated datagrids

  - by FauxReal

  Boy did I get an education looking into this. I guess I've been spoiled by Powerbuilder, which has fantastic functionality for this out of the box. Does anyone seriously write custom documentpaginator objects to handle reporting needs for their LOB apps? I want to be able to print "for free" and not have to code like crazy just to take whats on the screen and throw it on paper. How are people doing this? Does anyone have a recommended 3rd party for allowing printing of largish datagrids? Thanks

• Couldn't I just pass an copied string to an Core Data property?

  - by dontWatchMyProfile

  The docs say: The default implementation does not copy attribute values. If the attribute value may be mutable and implements the NSCopying protocol (as is the case with NSString, for example), you can copy the value in a custom accessor to help preserve encapsulation (for example, in the case where an instance of NSMutableString is passed as a value). So instead of getting into trouble and inconvenience with overwriting accessors in my NSManagedObject subclass, couldn't I simply do something like this? myManagedObject.firstName = [[firstNameMutableStr copy] autorelease]; This would have the exact same effect, or not? The dynamic implementation would retain that anyways ... so.... why not the easy way?

• Android changing colors with themes

  - by miannelle

  I am trying to provide user settable colors in my app. White text on black background and black text on white background. I have multiple layouts with many listviews, both standard and custom adapters. People have suggested using Themes, but I have had no luck changing the text colors across all layouts. Can anyone show me an actual Theme layout that can accomplish this? I can easily change the background colors using myscreen.setBackGroundColor(xx), but when I try to change the text with a theme, it also changes spinner text as well.

• Are ASP.NET readymade controls really production worthy ?

  - by Anil Namde

  I have come across the ASP.NET ready made controls like grid, repeater... etc. For example while dealing with GRID i remember following facts, ASP.NET V1.1 has DataGrid with "virtual row count" which is heavily used for custom paging which is need of big sites to perform well. ASP.NET V2.0 added the GridView with all sort of cool features but also split the DataSource parts as different component. Also "virtual row count" is not supported and for pagination to be done DataSource control is need to be used. After all these thing i thought that ASP.NET control are not made to be used as is for the development. Please let me know whether i am right or wrong? Also if you think i am wrong PLEASE provide inputs/links which can help me come out of this thinking of mine.

• Deserialising Json to derived types in Asp.Net Web API

  - by IoChaos

  I'm calling a method of my WebAPI sending a json that I would like to match (or bind) with a model. In the controller I have a method like: public Result Post([ModelBinder(typeof(CustomModelBinder))]MyClass model); 'MyClass', wich is given as a parameter is an abstract class. I would like that at, depending of the type of json passed, the correct inherited class is instantiated. To achieve it, I'm trying to implement a custom binder. The problem is that (I don't know if it's very basic but I can't find anything) I don't know how to retrieve the raw Json (or better, some kind of serialization) that comes in the request. I see: actionContext.Request.Content But all methods are exposed as async. I don't know who this fits with passing the generate model to the controller method... Thanks a lot!

• How to remove the auto added column (HeaderRole=Padding) in WPF GridView

  - by dnr3

  Hi, I'm trying to make a custom gridview in WPF but I just realized that as this link says: The GridViewHeaderRowPresenter class performs layout for the column headers in a GridView and places an additional column header at the end to add space and because of the additional column header at the end, there's an extra column to the right of the last column. so I was wondering if I can modify it, please refer to this image below My questions are: Is there anyway I can remove the 'A' part from the grid? Is there anyway I can add the same effect of 'B' part (the role = padding header) to the 'C' Part (before the first column)? Thanks

• Symfony: Pre filtering submitted values before/after validation

  - by Rob

  Hi All I've been scouring the net and i have found nothing! I am using symfonys form framework to build a simple 'Create' form. Validation is fine. However i'd like to pre-filter my submitted values, so adding ucfirst, strtoupper, and the like. I'm not sure if im missing something crucial here, but the way i see it is the only way to do this would be to create my own custom validators and utilizing the doClean method, which seems daft since i'd have hundreds of validators for each php function! Hope you guys can help, i've been crawling through source code, api's, numerous books and blogs and i haven't found a thing :( Either it's impossible, or it's really easy, i hope its the latter!

• Universal control - simple question about dock and anchor

  - by Vytas999

  I use Visual Studio .NET to develop internal applications. I create a Windows control that will display custom status bar information. Different developers will use the control to display the same information in many different applications. The control must always be displayed at the bottom of the parent form in every application. It must always be as wide as the form. When the form is resized, the control should be resized and repositioned accordingly. How should I do that in the best way and why? A)Create a property to allow the developers to set the Dock property of the control. Set the default value of the property to AnchorStyle.Bottom. B) Create a property to allow the developer to set the Anchor property of the control. Set the default value of the property to AnchorStyle.Bottom.

• Typed DataSet connection - required to have one in the .xsd file?

  - by Kyralessa

  In the .xsd file for a typed DataSet in .NET, there's a <Connections> section that contains a list of any data connections I've used to set up the DataTables and TableAdapters. There are times when I'd prefer not to have those there. For instance, sometimes I prefer to pass in a connection string to a custom constructor and use that rather than look for one in settings, .config, etc. But it seems like if I remove the connection strings from that section (leaving it empty), or remove the section entirely, the DataSet code-generation tool freaks out. Whereas if I don't remove them, the DataSet gripes when I put it in a different project because it can't find the settings for those connection strings. Is there any way I can tell a typed DataSet not to worry about any connections? (Obviously I'll have to give it a connection if I change any TableAdapter SQL or stored procs, but that should be my problem.)

• SharePoint form-based authentication problem with itemDeleting event?

  - by Clodin

  Hi! I have a SharePoint site (I'm the farm administrator with full control over the farm and site) and I used Windows authentication. I had a event receiver feature installed which manage add/update/delete for my lists to have custom behavior. Everything worked ok on Windows Authentication. But... now I am using form-based authentication (the same, I'm the site administrator with full control), but my feature works fine only with add/update events.... delete doesn't work any more, and it's the same code (damn it) as it was on windows authentication. Where am I doing wrong? why delete items don't work any more? Thanks in advance

• How do I get a UIView which displays text to behave like a UILabel when bounds change?

  - by Hilton Campbell

  I have a UIView in which I need to draw text in drawRect: - (void)drawRect:(CGRect)rect { ... [@"some text" drawAtPoint:somePoint withFont:someFont]; ... } Because the text requires special formatting, I cannot just use a UILabel. It looks fine until I rotate the device. Then the size of my custom UIView changes (in the parent view's layoutSubviews method), and the text becomes stretched in one direction and squished in the other. When I replace my view with a UILabel, the text always looks great, even when the bounds of the view changes. How can I get my view to exhibit the same behavior as UILabel? Some things I have looked into, but have yet to have success with: Set the view's layer's needsDisplayOnBoundsChange to YES. Set the view's contentStretch to CGRectZero. Call setNeedsDisplay in my view's layoutSubviews. Maybe I'm not doing one of these things right. Has anyone else run into this?

• Change update value of property (LINQTOSQL)

  - by Dynde

  Hi... I've got an entity object - Customer, with a property called VATRate. This VATRate is in the form of a decimal (0.25). I wanted to be able to enter a percentage value, and save it in the correct decimal value in the database, so I made this custom property: partial class Customer{ public decimal VatPercent { get{ ... //Get code works fine} set { this.VATRate = (value / 100); } } } And then I just bind this property instead of VATRate in my ASPX editTemplate (formview). This actually works - at least one time, when I debug an update, the value is set correctly one time, and then right after it gets set to the old value. I can't really see why it sets the value twice (and with the old value the second time). Can anyone shed some light on this?

• Separate groups of objects based on their properties

  - by Bevin

  I want to separate an array of my custom object into several arrays, based on the values of their two properties. The struct looks like this: struct MyStruct { public string Person { get; set; } public string Command { get; set; } } Now, if I have an array with a few objects: {Person1, cmd1} {Person1, cmd3} {Person2, cmd3} {Person3, cmd2} {Person2, cmd4} I want to be able to place them into one array for each person, that lists all of the commands for that person: {Person1: cmd1, cmd3} {Person2: cmd3, cmd4} {Person3: cmd2} I hope I've made it clear with my descriptions. I would assume that there is an elegant way to do this with LINQ, but I have no idea where to start.

• app.config and 64-bit machines

  - by Dale Lutes

  I have an app that works fine on 32-bit systems, but fails on XP 64 bit systems. I've tracked it down to the connection string defined in my app.config thus: <connectionStrings> <clear/> <add name="IFDSConnectionString" connectionString="Data Source=fdsdata;Initial Catalog=IFDS; Trusted_Connection=true;Connect Timeout=0" providerName="System.Data.SqlClient" /> </connectionStrings> When I try to reference it in code, I find that the ConfigurationManager.ConnectionStrings collection only contains the LocalSqlServer connection string from the machine.config file and not my custom string. Another oddity is that it works fine when I run the app out of Visual Studio. It is only when I run out of the release folder that the connection string does not get defined. The application's .exe.config file is there in the release folder along with the .exe file and is up to date.

• WPF layout calls MeasureOverride repeatedly in increments of 2?

  - by Scott Whitlock

  I've run into a case where I have a custom Panel (inherits from Panel) and I'm using it as an ItemsPanel in a ListView. When I resize the container that it's in, if I resize it smaller, my panel's MeasureOverride function gets called once, but if I resize it larger (let's say from 100 to 300), it calls MeasureOverride and ArrangeOverride for every value between 100 and 300, in increments of 2 (so 102, 104, etc.). The weird thing is that the container resizes right away (its size gets to 300 immediately). It doesn't seem to matter what I return from MeasureOverride - it just does this. I wish I could make it happen in a really small application and post it here, but I haven't been able to reproduce it like that yet. I can reproduce it all day in my app though. Does anyone know what could cause this?
