• JTable.setRowHeight prevents me from adding more rows

  - by Brent Parker

  I'm working on a pretty simple Java app in order to learn more about JTables, TableModels, and custom cell renderers. The table is a simple table with 8 columns only with text in them. When you click on an "add" button, a dialog pops up and lets you enter the data for the columns. Now to my problem. One of the columns (the last one) should allow for multiple lines of text. I'm already putting HTML into the field, but it is not wrapping. I did some research and looked into JTable#setRowHeight(). However, once I use setRowHeight, I can no longer add rows to the table. The data is put into the table model, but it does not show in the table. If I remove the setRowHeight line, then it adds data just fine. Is there another step to adding data to my data model that I'm missing? Thanks a lot!

• Creating a System.Web.UI.Page programatically in IHTTPHandler

  - by ObiWanKenobi

  I am trying to use the ASP.NET (3.5) "Routing Module" functionality to create custom pages based on the contents of the URL. Various articles, such as this one: http://blogs.msdn.com/mikeormond/archive/2008/05/14/using-asp-net-routing-independent-of-mvc.aspx explain how to use ASP.NET Routing to branch to existing pages on the web server. What I would like to do is create the page on-the-fly using code. My first attempt looks like this: public class SimpleRouteHandler : IRouteHandler { public IHttpHandler GetHttpHandler(RequestContext requestContext) { string pageName = requestContext.RouteData.GetRequiredString("PageName"); Page myPage = new Page(); myPage.Response.Write("hello " + pageName); return myPage; } } But this throws an HTTPException saying "Response is not available in this context." at the Response.Write statement. Any ideas on how to proceed? UPDATE: In the end, I went with an approach based on IHttpModule, which turned out to be rather easy.

• PHP DOMXml XPath of recursive Xpointer

  - by user256007

  My xml document reflects an Object. as referential Recursion is possible in objects and arrays. I need to reflect that in reproduced XML Structure too.

So is there any better/liteweight solution ?? might be XPointer or XLink (I am not sure). Any help ??

• Tarballing without git metadata

  - by zaf

  My source tree contains several directories which are using git source control and I need to tarball the whole tree excluding any references to the git metadata or custom log files. I thought I'd have a go using a combo of find/egrep/xargs/tar but somehow the tar file contains the .git directories and the *.log files. This is what I have: find -type f . | egrep -v '\.git|\.log' | xargs tar rvf ~/app.tar Can someone explain my misunderstanding here? Why is tar processing the files that find and egrep are filtering? I'm open to other techniques as well.

• C# UserControl factory

  - by user1112111

  Let's say you have two classes that extend UserControl. Each of the controls provides a custom event (this could be done by using an interface). You want to display one of the controls in the odd days and the other in the even days. You also want to be able to drag&drop (Visual Studio) the UserControl on your form without knowing what the Control type will finally be. How do you do that ? Is the factory pattern useful here ?

• Preventing the opening of a form on a add button click

  - by Jonathan

  Hey guys, Did you guys know how to prevent the open of a Form when I click on a add button? Maybe using beforeShowForm? function(formid) { if(jQuery('#gridap').getGridParam('selrow')) { idgridap=jQuery('#gridap').getGridParam('selrow'); jQuery('#FK_numerocontrato_ap',formid).val(idgridap).attr('readonly','readonly'); } else { // I want to prevent the openning of the add form here and maybe show an alert using the "alertcap" } } CHECAROW; $grid->setNavEvent('add','beforeShowForm',$checarowid); BTW, there's a way to call the alertmod of jqgrid and add a custom message to it? tks!

• How can I set a highlighted image on a table view cell?

  - by nevan

  I've followed the code in Apple's AdvancedTableViewCells and built a table view with a background image for cells. Now I want to change it so that instead of the blue highlight colour, it shows a darker version of my image. What are the steps I need to follow to do this? I'm using a UITableViewCell subclass with a custom NIB. My background image is implemented as the cell.backgroundView. The steps I've take so far are: Change the selectionStyle of the cell to "None" Set the Highlight colour on my UILabel subviews to a light colour Create a darker version of my background as a separate image Override setSelected: animated: I'm wondering about the next steps.

• Unit testing with django-celery?

  - by Jason Webb

  I am trying to come up with a testing methodology for our django-celery project. I have read the notes in the documentation, but it didn't give me a good idea of what to actually do. I am not worried about testing the tasks in the actual daemons, just the functionality of my code. Mainly I am wondering: How can we bypass task.delay() during the test (I tried setting CELERY_ALWAYS_EAGER = True but it made no difference)? How do we use the test settings that are recommended (if that is the best way) without actually changing our settings.py? Can we still use manage.py test or do we have to use a custom runner? Overall any hints or tips for testing with celery would be very helpful.

• Make NSFormatter validate NSTextFieldCell continuously

  - by harms

  In Cocoa, I have an NSOutlineView where the cells are NSTextFieldCell. The cell displays values which are strings that are formatted according to certain rules (such as floats or pairs of floats with a space in between). I have made a custom NSFormatter to validate the text, and this seems to work with no problem. However, the cell (or the outline view, I'm unsure what is causing this) only seems to use the formatter at the moment my editing would end. If I type some alphabetic characters into the text field (which violates the formatting rules), these characters show up -- the only way I notice the formatter doing its job is that I'm now prevented from moving keyboard focus away from this cell. If I return the contents of the cell to a valid form, then I can move focus away. I have set both the cell and the outline view to be "continuous". It would be better if I was unable to enter text into the cell in the first place. Is it possible to make it like that, and if so, how?

• Draw shadow under NSImage

  - by Tom Irving

  Currently I'm drawing an NSImage in a custom NSCell like so: - (void)drawInteriorWithFrame:(NSRect)theCellFrame inView:(NSView *)theControlView { // roundedCornerImage creates a new NSImage with rounded corners, rather than clipping. [[anIcon roundedCornerImage:5] drawInRect:anIconBox fromRect:NSZeroRect operation:NSCompositeSourceOver fraction:1.0]; } Very simply I'm wondering how to draw an image underneath it. On the iPhone, I would do this by using: CGContextSetShadow (currentContext, CGSizeMake(1, -1), 2); just before drawing the UIImage, but I'm unfamiliar with how to do it on the Mac. Any pointers would be great.

• flex datagrid re-assign dataprovider

  - by gauravgr8

  Hi, I am working on a datagrid with custom itemRenderer & [Bindable]xmllist as dataprovider. Now the changes done in xmllist are not reflected on datagrid UI until unless I re-assign the dataprovider as the same xmllist. As the dataprovider is Bindable so re-assigning is not required. But it was not working so I re-assigned the xmllist to the dataprovider of datagrid. It worked. Now my problem is when I re-assign the dataprovider my datagrid flicker(refreshes). It should not happen. 1) Is there any way out to avoid re-assigning of dataprovider? 2) Is there any way to stop flickering of datagrid on re-assigning the dataprovider? Thanks in advance.

• JComponent undock effect

  - by Christo Du Preez

  I'm trying to accomplish an undock effect for a custom Swing JComponent. By default the component is used inside a form along with other components. I want to be able to maximize this component to use the whole screen and then be able to dock it again. So far I've tested public void showDialog() { JFrame mainFrame = App.getApplication().getMainFrame(); JDialog dialog = new JDialog(mainFrame); dialog.setModal(true); dialog.setSize(800, 600); //Set to 80x660 for now dialog.add(this); //This is my JComponent dialog.setDefaultCloseOperation(JDialog.DISPOSE_ON_CLOSE); dialog.setVisible(true); } This gives me desired effect but when closing the dialog my component doesn't receive events no more. How can I prevent this? Or is there perhaps a better way to accomplish this?

• Getting the version of a COM object

  - by Shao

  I am accessing a .NET COM object from C++. I want to know the version information about this COM object. When I open the TLB in OLEVIEW.exe I can see the version information associated with the coclass. How can I access this information from C++? This is the information I get: [ uuid(XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX), version(1.0), custom(XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX, XXXX) ] coclass XXXXXXXX{ [default] interface XXXXXXXX; interface _Object; interface XXXXXXXX; };

• Wrangling Control of HTTP Headers in ASP.NET

  - by Andrew Burgess

  I'm working with ASP.NET MVC3, and I'm trying to get absolute control over my headers because a client application that I'm working with expects a very specific content type. What I'm finding when using Fiddler to examine the HTTP traffic is that the text encoding is being returned as part of the header. For example, the client is expecting application/appname in the Content-Type header, but the server is returning application/appname; charset=utf-8. I think the client is using a strict comparison for checking the type, so I want to be able to specify exactly what is emitted in the headers. Right now I have a custom ActionResult in which I clear the headers and then specify only the content type, but the encoding still seems to be added on. How can I remove the encoding from the Content-Type header?

• SQLite as an App Queue, Exclusive Row Lock?

  - by ScSub

  I am considering using SQLite as a "job queue container", and was wondering how I could do so, using custom C# (with ADO.NET) to work the database. If this was SQL Server, I would setup a serializable transaction to make sure the parent row and child rows were exclusively mine until I was done. I'm not sure how that would work in SQLite, can anyone offer any assistance? Or if there are any other existing implementations of message queueing with SQLite, I'd appreciate any pointers in that direction as well. Thanks!

• paypal redirect on successful checkout

  - by Graeme Leighfield

  I am trying to get my Paypal subscription to redirect to a custom page after a successful checkout. Before submitting to Paypal I overload the submit handler, run my own function (to store details) and return a unique id. I want to attach that id to my return URL. (as a GET or POST var so to speak) I have turned auto redirect "on" in my Paypal sandbox sellers preferences, but it only seems to re-direct to the URL that I HAVE to put in there. using the <input type="hidden" name="return" value="someurl" /> does no seem to work. I want it this way so that I can capture the user information when entered with a "non-paid" flag, then via the IPN I can update that record with a "PAID" flag, and I want to use the unique ID to tie it all together so to speak. Any advice or a different approach is welcomed. Many thanks!

• iPhone: Core Data: Updating a pre-filled database in future app versions.

  - by Cuzog

  I am creating an app with a database of information that needs to be pre-filled. This data will change in future versions. In the same database, I also need to store user editable information since that user edited data directly relates to the pre-filled data. My question is, if I'm pre-filling the database by creating a duplicate data model in a second app and copying over the core data file before release, how would I handle updates to that data in future versions of the app without destroying the user's existing data? Do the core data migration methods handle this, or must I write custom methods to programatically handle the merge at first app launch?

• Doing Forms With Just Windows SharePoint Services 3.0?

  - by tekiegreg

  For the most part my organization is happy with WSS 3.0 (no upgrading to MOSS) with one exception, there is really just one form we'd like to put up somehow. It's fairly big form (basically change requests for IT services, on paper it's easily 2 full 8.5 by 11 pages). We thought about Custom ASP.NET coding as a separate stand-alone page or maybe as a web part. What have other people out there done? MOSS and Infopath is not really an option as it really is too expensive for us at this time. Thanks in advance!

• How can I make a DateTimePicker display an empty string?

  - by brass-kazoo

  I would like to be able to display a DateTimePicker that has a default value of nothing, i.e. no date. For example, I have a start date dtTaskStart and an end date dtTaskEnd for a task, but the end date is not known, and not populated initially. I have specified a custom format of yyyy-MM-dd for both controls. Setting the value to null, or an empty string at runtime causes an error, so how can I accomplish this? I have considered using a checkbox to control the enabling of this field, but there is still the issue of displaying an initial value.. Edit: Arguably a duplicate of the question DateTimePicker Null Value (.NET), but the solution I found for my problem is not a solution for that question, so I think it should remain here for others to find..

• How do I create a class associated with a windows form in C#?

  - by xarzu

  Now that C++ development has become second nature to me, do I have to start from scratch with C#? Since the beginning of Visual Studio, there has been easy way to describe the shape of a Dialog (now called a Form) in the resource file and then use a wizard to create the corresponding C++ code. I kind of remember that in MFC it was pretty much a no-brainer to create a custom dialog with all the components you want and then all the associated code. If I have a C# app that has many forms that I want to bring to the screen based on the user's menu selections, how do I create a class associated with a windows form?

• Exporting info from PS script to csv

  - by George

  Hi, This is a powershell/AD/Exchange question.... I'm running a script against a number of Users to check some of their attributes however I'm having trouble getting this to output to CSV. The script runs well and does exactly what I need it to do, the output on screen is fine, I'm just having trouble getting it to directly export to csv. The input is a comma seperated txt file of usernames (eg "username1,username2,username3") I've experimented with creating custom ps objects, adding to them and then exporting those but its not working.... Any suggestions gratefully received.. Thanks George $array = Get-Content $InputPath #split the comma delimited string into an array $arrayb = $array.Split(","); foreach ($User in $arrayb) { #find group memebership Write-Host "AD group membership for $User" Get-QADMemberOf $User #Get Mailbox Info Write-Host "Mailbox info for $User" Get-Mailbox $User | select ServerName, Database, EmailAddresses, PrimarySmtpAddress, WindowsEmailAddress #get profile details Write-Host "Home drive info for $User" Get-QADUser $User| select HomeDirectory,HomeDrive #add space between users Write-Host "" Write-Host "******************************************************" } Write-Host "End Script"

• How can I detect if the Solution is initializing using the DTE in a VisualStudio extension?

  - by justin.m.chase

  I am using the DTE to track when projects are loaded and removed from the solution so that I can update a custom Test Explorer extension. I then trigger a container discovery process. But when the solution is first loaded it does an asynchronous load of some projects and fires a lot of Project Added events. What I would really like to do is to ignore all of these events until the solution is done loading. I can't quite figure out the order of events such that I know for sure that this initialization process has completed. It would be really nice to be able to just query the solution object and ask it. Does anyone know if there is a property or interface or event that I can use to determine this?

• How do I rotate an image in Javascript or CSS

  - by Eric

  I am creating a simple game. I want to use jQUERY to rotate the joints making it move. I am using .animate ( http://api.jquery.com/animate/ ) to animate CSS properties but if it is also possible to use Javscript, I can make my own custom code. More TO-THE-POINT How do I rotate images in CSS or Javascript? I prefer CSS but Javascript is fine too. If it is impossible (which I am pretty sure it is but I am not giving up yet) is there any other possible way to do what i am trying to do without making a bunch of seperate images, each rotated a different way. Or can anyone at least give me an example of a site that does something similar. EDIT: I need 1 CSS property (no -something: rotation(500deg);) that works with FireFox, Safari and Chrome because those are the only browsers I really work with.
