• Custom control in DataViewGrid

  - by Winston

  I'm trying to embed a custom control in a Datagridview. I've looked at the Calendar (http://msdn.microsoft.com/en-us/library/7tas5c80.aspx) example but i just cant get it working for a custom control. I need the control to show for each object in the grid. Not just when the user edits the content. I need to do this so that i can bind my dataviewgrid to a datasource and have it create the required forms in the grid for each my object list. So that the user can do inline editing in the grid without having to double click the row and have a new dialog pop up. Any help would be greatly appreciated.

• Editting ForeignKey from "child" table

  - by profuel

  I'm programming on py with django. I have models: class Product(mymodels.Base): title = models.CharField() price = models.ForeignKey(Price) promoPrice = models.ForeignKey(Price, related_name="promo_price") class Price(mymodels.Base): value = models.DecimalField(max_digits=10, decimal_places=3) taxValue = models.DecimalField("Tax Value", max_digits=10, decimal_places=3) valueWithTax = models.DecimalField("Value with Tax", max_digits=10, decimal_places=3) I want to see INPUTs for both prices when editing product, but cannot find any possibility to do that. inlines = [...] works only from Price to Product, which is stupid in this case. Thanx for adnvance.

• Edit the opposite side of a many to many relationship with django generic form

  - by Ed

  I have two models: class Actor(models.Model): name = models.CharField(max_length=30, unique = True) event = models.ManyToManyField(Event, blank=True, null=True) class Event(models.Model): name = models.CharField(max_length=30, unique = True) long_description = models.TextField(blank=True, null=True) In a previous question: http://stackoverflow.com/questions/2503243/django-form-linking-2-models-by-many-to-many-field, I created an EventForm with a save function: class EventForm(forms.ModelForm): class Meta: model = Event def save(self, commit=True): instance = forms.ModelForm.save(self) instance.actors_set.clear() for actor in self.cleaned_data['actors']: instance.actors_set.add(actors) return instance This allowed me to add m2m links from the other side of the defined m2m connection. Now I want to edit the entry. I've been using a generic function: def generic_edit(request, modelname, object_id): modelname = modelname.lower() form_class = form_dict[modelname] return update_object(request, form_class = form_class, object_id = object_id, template_name = 'createdit.html' ) but this pulls in all the info except the many-to-many selections saved to this object. I think I need to do something similar to this: http://stackoverflow.com/questions/1700202/editing-both-sides-of-m2m-in-admin-page, but I haven't figured it out. How do I use the generic update_object to edit the other side of many-to-many link?

• CKEditor 3.2 is un-editable in jQuery simpleModal

  - by Gal V

  Hello all, I noticed that this isn't the first time that this issue comes up, but I still couldn't find the right and working solution for me. Here is the thing- In my ASP.NET aspx page I created a div element, with a <cc1:CKEditor> control tag within it. This div is hidden, and is attached to a jQuery SimpleModal plugin. The problem is- that when I trigger the modal-opening and the modal shows up with the editor within it, the editor is UNEDITABLE, locked. How can I fix it, and enable the editing in the CKEditor's textarea? Thanks in advance!

• Libraries/Solutions for using XSL to create interactive web forms from XML

  - by Brabster

  This seems like a pretty straightforward thing to do, but I can't find anything off the open-source shelf. Is there a solution already out there that does the following: can be configured with an arbitrary XSL stylesheet generates a web form based on an arbitrary XML document and the XSL creates edit functionality in appropriate places in the rendered form updates the local representation of the XML document provides capabilities to view, save the new XML document Ideally, one that plugs into a Java web application. Even better if it can generate the XSL based on schema documents - but that might not be feasible, not really thought it through. For context, I'm thinking things like pleasant-for-humans editing of Maven POMs, ANT build.xml, etc. Cheers,

• How can I copy a file from VMS to Windows and back again?

  - by Matt Joslin

  I am trying to copy C source files from a vms alpha to a windows machine to allow easier editing of the code. (VMS editor is just a text editor and it would be nice to have syntax highlighting etc) I can copy this across using Exceed FTP and this handles the issue of duplicate filenames with version suffix that vms has: File.c;1 File.c;2 Flle.c;3 But when I open a file I've transferred, all the line breaks have been lost and the entire file is just one line. Can anyone recommend a solution to this or offer any hints? Thanks in advance ps. I need to be able to copy the files back to vms and still maintain format.

• Making DiveIntoPython3 work in IE8 (fixing a Javascript performance issue)

  - by srid

  I am trying to fix the performance problem with Dive Into Python 3 on IE8. Visit this page in IE8 and, after a few moments, you will see the following popup: I traced down the culprit down to this line in j/dip3.js ... find("tr:nth-child(" + (i+1) + ") td:nth-child(2)"); If I disable it (and return from the function immediately), the "Stop executing this script?" dialog does not appear as the page now loads fairly fast. I am no Javascript/jquery expert, so I ask you fellow developers as to why this query is making IE slow. Is there a fix for it? Edit: you can download the entire webpage (980K) for local viewing/editing.

• edit opencart header.tpl

  - by user1693350

  I'm trying to edit the header.tpl of an opencart website that uses vqmod - I need to add some more info (text) to each menu link, so basically edit the header file. I've looked into the vqmod manager and files but I can't seem to get it right. Unfortunately, whenever I try to edit the header file, the site breaks -I've tried editing the cached vqmod files as well, no luck with that. Is there a way to reset the vqmod / disable it, then edit the header.tpl and enable vqmod again? Do I need to install a new theme and start from scratch ? Thanks heaps!

  I have a Silverlight Datagrid, I'd like to make certain cells readonly programmatically. Specifically I have a CellEditingTemplate, I'd like to turn the cell editing off or on depending on the value of CategoryTypeName (see the xmal below). <local:DataGridTemplateColumn Header="Category" > <local:DataGridTemplateColumn.CellTemplate> <DataTemplate> <TextBlock Text="{Binding CategoryTypeName}"/> </DataTemplate> </local:DataGridTemplateColumn.CellTemplate> <local:DataGridTemplateColumn.CellEditingTemplate> <DataTemplate> <ComboBox Width="90" x:Name="CategoryCombo" ItemsSource="{Binding CategoryTypes}" DisplayMemberPath="Name" SelectionChanged="CategoryCombo_SelectionChanged" /> </DataTemplate> </local:DataGridTemplateColumn.CellEditingTemplate> </local:DataGridTemplateColumn> Is there a way to do this?

• Rails - building an absolute url in a model's virtual attribute without url helper

  - by Nick

  I have a model that has paperclip attachments. The model might be used in multiple rails apps I need to return a full (non-relative) url to the attachment as part of a JSON API being consumed elsewhere. I'd like to abstract the paperclip aspect and have a simple virtual attribute like this: def thumbnail_url self.photo.url(:thumb) end This however only gives me the relative path. Since it's in the model I can't use the URL helper methods, right? What would be a good approach to prepending the application root url since I don't have helper support? I would like to avoid hardcoding something or adding code to the controller method that assembles my JSON. Thank you

• Can I use android.os.* libraries in a standalone project?

  - by medicdave

  I'm trying to develop an external library (not sure if that's the right term) to provide prepackaged functionality in Android projects. Working in Eclipse, I've added the appropriate android.jar file to the build path, and everything is happy both while editing and upon compilation. However, when I use Android's Handler and Message classes (android.os.Handler, android.os.Message) for inter-thread communication, I get exceptions unless I'm running within an Android app, on the emulator or a device. I can no longer test my library in a "standalone" way without having to go through a running Android target. Is there any way for me to include these two Android classes and still be able to test my library standalone? Do I need to have the Android source available? Or would it require some sort of conditional compilation hand-waving?

• Save UITextView content in NSString.

  - by camilo

  Hi, I'm trying to save the contents of an UITextView into a NSString which I will somehow persist later. The problem is that the UITextView "text" property doesn't save all the rows in the textView (after touching "return"). I tried print the TextView object and the textView.text, and they're different. Does anybody know how (after editing the textView) I can save its content into a String (or something else that I can later access and share through different views and persist in the database)? Thanks a lot. Pretty sure it is simple, but I'm honestly not finding the solution.

• Changing <img src="XXX" />, js event when new image has finished loading?

  - by carillonator

  I have a photo gallery web page where a single <img src="XXX" /> element's src is changed (on a click) with javascript to show the next image—a poor man's ajax I guess. Works great on faster connections when the new image appears almost immediately. Even if it takes a few seconds to load, every browser I've tested it on keeps the old image in place until the new one is completely loaded. It's a little confusing waiting those few seconds on a slow connection, though, and I'm wondering if there's some javascript event that fires when the new image is done loading, allowing me to put a little working... animated gif or something up in the meantime. I know I could use AJAX for real (I'm using jQuery already), but this is such a nice and simple solution. Besides this lag, is there any other reason I should stay away from this approach to changing images? thanks.

• Setting up a (web) development environment

  - by mnml

  Hi, I would like to know how I can improve my development environment. At the moment: I'm using Netbeans as my IDE. My local Dev server runs on a RHEL5 VirtualMachine similar to my production server. My Netbeans project is editing the VM files via ssh (I have mounted the server as a local drive) But: It's slow Files can disapear ( netbeans delete them ? ) I can't use git on it because it's slow. The idea would be to be able to have a shared filesytem between the guest os and the host os.

• mediawiki markup equivalent of WMD live-previewing editor? (not WYSIWYG)

  - by Justin Grant

  Anyone have a recommendation for an editor like the WMD editor, but using MediaWiki markup instead of Markdown? Our site is already using MediaWiki markup but we want a slicker editor without changing markup completely. Requirements include: live preview of formatted text underneath the markup you're typing a toolbar for common formatting (bold, italic, links, bullets, numbered-list, code, etc) keyboard shortcuts for each toolbar button (e.g. CTRL+B for bold) Undo/redo via keyboard shortcuts (CTRL+Z/CTRL+Y) or toolbar buttons works well in the usual set of popular browsers (including IE6!) open-source would be preferred I've found a few options at http://www.mediawiki.org/wiki/WYSIWYG_editor, but all of these seem to be WYSIWYG editors which is not exactly what I want since full-on WYSIWYG editors tend to be bug-prone and complicate working at the markup level. Instead we want a plain-text markup editor with a client-side previewer, plus some UI niceties (toolbar, undo, keyboard shortcuts) to make editing markup easier.

• How to store millions of pictures about 2k each in size

  - by LuftMensch

  We're creating an ASP.Net MVC site that will need to store 1 million+ pictures, all around 2k-5k in size. From previous ressearch, it looks like a file server is probably better than a db (feel free to comment otherwise). Is there anything special to consider when storing this many files? Are there any issues with Windows being able to find the photo quickly if there are so many files in one folder? Does a segmented directory structure need to be created, for example dividing them up by filename? It would be nice if the solution would scale to at least 10 million pictures for potential future expansion needs.

• tcpdf - HTML table showing up way too small

  - by LinuxGnut

  Hi folks. I'm using tcpdf (http://www.tcpdf.org/) to generate PDFs of some tables and images. The images are loaded without an issue, but I'm having issues with the writeHTML() function. I can't seem to control the font sizes or table width/height through the HTML, so I end up with a tiny, tiny, tiny table that you have to print of and squint at to even attempt reading. I've tried editing the table itself, CSS, even putting the table itself inside an h1, but nothing is changing the font size. I have the font size in tcpdf set to 16, but this also has no affect. Has anyone else run into this issue?

• GIS: When and why to use ArcObjects over GDAL programming to work with ArcGIS rasters and vectors?

  - by anotherobject

  Im just starting off with GDAL + python to support operations that cannot be done with ArcGIS python geoprocessing scripting. Mainly I am doing spatial modeling/analysis/editing of raster and vector data. I am a bit confused when ArcObject development is required versus when GDAL can be used? Is there functionality of ArcObjects that GDAL does not do? Is the opposite true too? I am assuming that ArcObjects are more useful in developing online tools versus Desktop analysis and modeling where the difference is more to do with preference? In my case i prefer GDAL because of python support, which I believe ArcObjects lack. thanks!

• How is includegraphic interfering with tabular?

  - by Charles Stewart

  I'm editing a text provided by my client as a LyX file that includes graphics and other files that I don't have. I've "commented out" the graphics by putting in a custom preamble that substitutes the file-loading definitions with macros that just quote their arguments. However, the \includegraphic macro throws up an error in the two tabular environments where it is used, complaining that \endfirsthead was never defined. What is this macro, and why is it interfering with mine? The preamble: \usepackage{natbib} \def\fileloc{/some/path/stylefile} \newif\iftextproof \IfFileExists\alifefileloc\textproofalse\textprooftrue \iftextproof \usepackage{./stylefile} %natbib subst: \renewcommand\cite[1]{{\tt #1}} %suppress graphics includes: \def\quotearg#1{\expandafter\string\csname #1\endcsname} \newcommand\gobbleIG[2][*void*]{{\footnotesize \quotearg{#2}}} \newcommand\gobbleSF[2][*unnamed*]{{\bf #1}} \let\includegraphics=\gobbleIG \let\subfigure=\gobbleSF \else \usepackage\fileloc \fi

• Issues dismissing keyboard conditionally with on iPhone

  - by Chris

  I have an app that has a username and password field. I want to validate the input before the the user is allowed to stop editing the field. To do that, I'm using the textFieldShouldEndEditing delegate method. If the input doesn't validate I display a UIAlertView. This approach works as advertised - the user cannot leave the field if the input doesn't validate. To have the done button on the keyboard dismiss the keyboard, I call resignFirstResponder on the textfield. The issue I have is the alert is being called twice. How do I keep the alert from showing twice?

• Why does the "choose files" button not work in Wordpress 2.5 when trying to upload photos?

  - by Great Kindness

  I've got Wordpress 2.5 installed on my website. It works well, but I can't get the photo uploader to work. When I'm writing a post, I click on the "Add media" button. In the "Choose File" tab, I see the "Choose files to upload" button. When I click on it, nothing happens. I searched the net and found nothing helpful. One page vaguely mentioned having the latest Flash player. I verified and confirmed that I have the latest player. Any ideas?

• Developer oriented hardware benchmarks?

  - by Promit

  Perhaps I'm looking in the wrong places, but every hardware benchmark I've found, for nearly any component, is oriented towards gamers and/or workstations (video editing etc). Is there anyone doing benchmarks that are relevant to software developers? For example, take SSDs. I don't care how fast Crysis loads off an SSD -- that is completely worthless information. What I want to know is, which drive yields the quickest build times? What about Intellisense and refactoring operations? What RAID configuration has the biggest benefit? I could probably come up with more examples, but you get the point. Long story short, where are the benchmarks that tell me which hardware will be most effective in helping me be a productive software developer?

• Displaying Photos on iPhone

  - by Bjorn S.

  Hi all, I'm working on an iPhone app and I need to be able to display images to users. I have already gotten the code that takes the photo and stores it into the filesystem working well. Now I just need to figure out how to display the image. I've looked at the Three20 project I've read about on a few of the posts here, but it seems a bit cumbersome and like an extra dependency to import link and combine all of the Three20 library into my little app. Are there any other ways or a more streamlined library that will let me display photos to my users? Thanks! B.
