• Unit testing "hybrid" WPF/Silverlight controls

  - by Alan Mendelevich

  I'm starting a new WPF/Silverlight custom control project and wanted to do unit testing on this one. However I'm a little confused about how to approach this. This control would be based on the same codebase for both WPF and Silverlight with minor forking using #ifs and partial classes to tame the differences. I guess I could write unit tests for WPF part with NUnit, MSTest, xUnit, etc. and for the Silverlight part with Silverlight Unit Test Framework but this doesn't sound very elegant to me. I'd have to either ignore testing identical code on one of the platforms and test only differing parts (which is not very trustworthy) or rewrite tests for 2 frameworks (which is annoying). Is this the right way to go? I'm wondering if there's some guidance, articles, tutorials out there on how to approach this task. Any pointers?

• Simple non-network concurrency with Twisted

  - by Rince

  Dear pythoners, I have a problem with using Twisted for simple concurrency in python. The problem is - I don't know how to do it and all online resources are about Twisted networking abilities. So I am turning to SO-gurus for some guidance. Python 2.5 is used. Simplified version of my problem runs as follows: A bunch of scientific data A function that munches on the data and creates output ??? < here enters concurrency, it takes chunks of data from 1 and feeds it to 2 Output from 3 is joined and stored My guess is that Twisted reactor can do the number three job. But how? Thanks a lot for any help and suggestions.

• Dynamics CRM Get Info For Customer

  - by macinjosh

  I'm working on a ASP.NET (C#) site that pulls most of its data from Dynamics CRM over SOAP using Microsoft's CrmService SDK. I'm at the point where a query has returned an entity with a property of the type Customer. I need to get the name string of that customer record, but cannot figure out how to do so. By doing a little guess work I figured out that what I have is GUID for the customer. How can I use this GUID to get the customer's name as a string?

• C: Compiling GNU Projects on Windows

  - by Shiftbit

  I would like to port a few applications that I use on Linux to Windows. In particular I have been working on wdiff. A program that compares the differences word by word of two files. Currently I have been able to successfully compile the program on windows through Cygwin. However, I would like to run the program natively on Windows similar to the Project: UnixUtils. How would I go about porting unix utilities on a windows environment? My possible guess it to manually create the ./configure file so that I can create a proper makefile. Am I on the right track? Has anyone had experience porting GNU software to windows?

• Getting Image size of JPEG from its binary

  - by rajeshsr

  Hi I have a lot of jpeg files with varying image size. For instance, here is the first 640 bytes as given by hexdump of an image of size 256*384(pixels): 0000000: ffd8 ffe0 0010 4a46 4946 0001 0101 0048 ......JFIF.....H 0000010: 0048 0000 ffdb 0043 0003 0202 0302 0203 .H.....C........ 0000020: 0303 0304 0303 0405 0805 0504 0405 0a07 ................ 0000030: 0706 080c 0a0c 0c0b 0a0b 0b0d 0e12 100d ................ I guess the size information mus be within these lines. But am unable to see which bytes give the sizes correctly. Can anyone help me find the fields that contains the size information?

• Sorting array containing strings in objective c

  - by jakob

  Hello experts! I have an array named 'names' with strings looking like this: ["name_23_something", "name_25_something", "name_2_something"]; Now I would like to sort this array in ascending order so it looks like this: ["name_25_something", "name_23_something", "name_2_something"]; I guess that should start of with extracting the numbers since I want that the sorting is done by them: for(NSString *name in arr) { NSArray *nameSegments = [name componentsSeparatedByString:@"_"]; NSLog("number: %@", (NSString*)[nameSegments objectAtIndex:1]); } I'm thinking of creating a dictionary with the keys but I'm not sure if that is the correct objective-c way, maybe there some some methods I could use instead? Could you please me with some tips or example code how this sorting should be done in a proper way. Thank you

• Checkbox 'Checked' in ListView is restored after scrolling

  - by adrianrdzv

  I'm having the following problem: I have a ListActivity, which its ListView is composed by an icon, text and a checkbox (using LayoutInflater). The Adapter for the ListView extends ResourceCursorAdapter (i.e. the data source of the ListView is retrieved from a database, also the Checked status of each row) Everything works pretty Ok, except when I uncheck/check the checkbox in any row, if I scroll down until the modified checkbox is no longer visible, and then scroll up, the checkbox is restored to its original state. The database IS modified, this is not the problem (i.e. if I modify a row and exit the activity, and enter again, the modified row is displayed Ok). My guess is that this has something to do on how the list is rendered because for some reason the ListView "renders" the original state of all rows when it was first populated when scrolling. I've been looking around for this bug but I don't find anybody that had this problem. I appreciate any advice you have.

• Flash FLVPlayback states

  - by rob5408

  I'm writing my own class to manage a skin for an FLVPlayback component. It works 90% of the time, but sometimes the state get really messed up. Specifically, the video is playing, meaning I can see it play and the VideoEvent.PLAYHEAD_UPDATE event is firing, but when I poll the FLVPlayback component about its playing property, it returns false. I assume this may be because 'buffering' is kind of a subset of 'playing', but I cannot confirm this in the documentation. I guess another way to ask this question is, "Does the FLVPlayback component ever buffer while it is in a stopped state?"

• When is referential integrity not appropriate?

  - by Curtis Inderwiesche

  I understand the need to have referential integrity for limiting specific values on entry or possibly preventing them from removal upon a request of deletion. However, I am unclear as to a valid use case which would exclude this mechanism from always being used. I guess this would fall into several sub-questions: When is referential integrity not appropriate? Is it appropriate to have fields containing multiple and/or possibly incomplete subsets of a foreign key's list? Typically, should this be a schema structure design decision or an interface design decision? (Or possibly neither or both) Thoughts?

• Store html form on client or server while building?

  - by Brett

  Hi, I have a fairly complex html form enhanced via jquery. It has multiple tabs, within each one things like a html form builder, uploads, descriptions. There is lots of data, and as the user flicks around the various tabs I'm thinking of posting the data to the server. For example, the form builder, has about 10 properties for each field, as the user flicks between the various fields, an ajax request saves the current values, then loads a new set from the new field clicked on. When the user hits save, the idea is then on the server all these bits and pieces come together and become the live version (i may store them as a temp version while the user is working away). So I guess my question is, for complex forms where the same fields are re-used within the one form, does anyone attempt to save all this data locally and upload it in one hit or do most of you do little ajax post's and compile it all when the final save button is hit? b

• Process-wide hook using SetWindowsHookEx

  - by mfya

  I need to inject a dll into one or more external processes, from which I also want to intercept keybord events. That's why using SetWindowsHookEx with WH_KEYBOARD looks like an easy way to achieve both things in a single step. Now I really don't want to install a global hook when I'm only interested in a few selected processes, but Windows hooks seem to be either global or thread-only. My question is now how I would properly go about setting up a process-wide hook. I guess one way would be to set up the hook on the target process' main thread from my application, and then doing the same from inside my dll on DLL_PROCESS_ATTACH for all other running threads (plus on DLL_THREAD_ATTACH for threads started later). But is this really a good way? And more important, aren't there any simpler ways to setup process-wide hooks? My idea looks quite cumbersome und ugly, but I wasn't able to find any information about doing this anywhere.

• Java->Scala Remove Iterator<T>-Element from a JavaConversions-wrapped Iterable

  - by ifischer

  I have to translate the following code from Java to Scala: for (Iterator<ExceptionQueuedEvent> i = getUnhandledExceptionQueuedEvents().iterator(); i.hasNext();) { ExceptionQueuedEvent event = i.next(); try { //do something } finally { i.remove(); } } I'm using the JavaConversions library to wrap the Iterable. But as i'm not using the original Iterator, i don't know how to remove the current element correctly from the collection the same way as i did in Java: import scala.collection.JavaConversions._ (...) for (val event <- events) { try { //do something } finally { //how can i remove the current event from events? } } Can someone help me? I guess it's easy, but i'm still kinda new to Scala and don't understand what's going on when Scala wraps something of Java.

• ReportViewer height issue. Hiding scrollbars.

  - by Tommy Jakobsen

  Hi, I'm using MSSQL 2005 Reporting Services and in this case I need to display some reports on an ASP.NET page using the ReportViewer control (I guess thats the only way, right?). The problem is that I can't get the property SizeToReportContent to work. When displaying the report, I get a vertical scrollbar because the report is too large. It looks like an iframe window. Searching on google it seems to be a bug. It can be fixed by setting AsyncRendering to false but I don't want that. I need another solution. I was wondering if it's possible to set the height on the report element using JavaScript after the report has been loaded? Or do you know of another solution? This is really annoying. Thanks in advance.

• Can I use the whatthetrend.com API to get daily and weekly twitter trends?

  - by Charles S.

  The twitter API allows me to receive daily trends and weekly trends (in addition to current trends, of course) as either JSON or XML. Is there an equivalent with the whatthetrend.com API? I don't see a method/parameter at first glance but I wanted to see if anyone out there knew a way... http://api.whatthetrend.com/api There's a method to lookup trend definition by keyword so I guess I could use that based off the Twitter API but I'd rather just load all the data at once rather than have to remotely access the API every time I want to look up a definition. Thanks

• How to develop a Google Gadget compatible server

  - by Peter Stegnar

  I am going to develop a Google Gadget container site, that will be able to host OpenSocial compatible widgets (that I believe are Google gadgets, too, right?). Do you have any guidance where to start? I know that the good start is the iGoogle Developer Home site and that framework what I would like exists - Shindig, but is little clumsy. Tutorial links do not work, for start. Do you think it would be wise to use Shindig? Maybe just for a start and then develop any customizations, if needed? Or would be wiser to start from scratch? So where to start? Do you have any advices, tips or other useful resources to get on faster with this topic? I guess I can start with Compliance - Gadget Server?

• Is WPF a good choice for developing line of business user interfaces?

  - by Randy Minder

  We're debating whether our future Windows UI development should be WinForms or WPF. How have some of you made this decision? Most of our applications are LOB applications, and I'm not sure I see a clear and overwhelming benefit to WPF for these types of applications. However, my knowledge of WPF is limited. I'm also a little concerned that WPF will be in vogue for another couple years and then Microsoft will get tired of it and push something else on us. I guess one argument against this is the fact that Visual Studio 2010 is a WPF application. Thanks.

• How to retrieve JSON Data Array from ExtJS Store

  - by user291928

  Is there a method allowing me to return my stored data in an ExtJS Grid Panel exactly the way I loaded it using: var data = ["value1", "value2"] Store.loadData(data); I would like to have a user option to reload the Grid, but changes to the store need to be taken into account. The user can make changes and the grid is dynamically updated, but if I reload the grid, the data that was originally loaded is shown even though the database has been updated with the new changes. I would prefer not to reload the page and just let them reload the grid data itself with the newly changed store. I guess im looking for something like this: var data = Store.getData(); //data = ["value1", "value2"] after its all said and done. Or is there a different way to refresh the grid with new data that I am not aware of. Even using the proxy still uses the "original" data, not the new store. Thanks in advance

• How to browse a Matrix returned by the OpenCV2.0 Canny() function ?

  - by user290613

  Hi all, I've been browsing the web to get an answer but no way to put my hand on it. I call the Canny function that fills me a matrix Canny(src, dst, 220, 299, 3 ); the dst variable is now a Matrix that is according to me of type CV_8UC1, 8bit, 1channel. Now I would like to browse this matrix according to rows and columns, so there was a trick that I've seen on stackoverflow dst.at<uchar*>(3, 5) In my case it crashes. (Assertion Failed, unknown function, cxmat.hpp line 450) My matrix information are myMatrix.width() = 181 myMatrix.height() = 65 One more thing, when I do std::cout << dst.depth() << std::endl; It always retrieves me 0 and not 8 (which I guess Im suppose to get) Thank you very much for all who will reply,

• Jagged Edge Arrays in PHP

  - by chriscct7

  I want to store some data in (I guess a semi-2, semi-3d array) in PHP (5.3) What I need to do is store data about each floor like this: Floor Num of Spots Handicap Motorcyle Other 1 100 array(15,16,17) array (47,62) array (99,100) 2 100 array(15,16,17) array (47,62) array (99,100) and on The problem is, is if the Handicap+Motorcyle+Other were ints, I could just store the data in a 2d array. However, they aren't. So I was thinking I could make something almost like a 3D array, with the first two columns only being in 2D. The other thought I had was making a 2D array and for columns 3,4, and 5 instead of saving as array(15,16) //save like 1516 And then split at two digits (1 digit array numbers would be prefaced with a 0). However, I am wondering about the limit of the length of a string, because if I decide to move to a 3 digit length number in the array, like array(100, 104), and I need to store alot of numbers, I am thinking I am going to quickly exceed the max.

• How to implement a countdown clock on a product launch web page?

  - by Daniel Earwicker

  I'm asking this on behalf of a certain corporation: http://www.microsoft.com/visualstudio/en-us/watch-it-live Things to bear in mind: It's 8:30 AM at different times depending on where you are in the world. For example, where I am, it is already 10 AM, whereas in Redmond it's still only 2 AM. That's probably the main thing, I guess. Can any SO users recommend ways to improve the existing countdown page so that it works correctly for users in any timezone? (Serious question - clearly this is a pit that is easy to fall into!)

• Checking if file exist with RewriteCond in a chained RewriteRule

  - by gelilloabad

  Hello, I hope you could help me here. I have a RewriteRule which gives you a crossdomain.xml file depending on the domain name. I have it in a way that ignores the ".dev." string in the middle, example: Request: http://site1.dev.mydomain.com/crossdomain.xml Returns file: /etc/httpd/conf/crossdomain/site.mydomain.com.xml RewriteCond %{HTTP_HOST} "^(.*)\.dev\.(.*)" RewriteCond %{REQUEST_URI} "/crossdomain.xml" enter code hereRewriteRule ^(.+) %{HTTP_HOST}$1 [C] RewriteRule ^(.*)\.dev\.([^/]*)/crossdomain.xml /etc/httpd/conf/crossdomain/$1.$2.xml [L] Question: How do I check if the file exists? I tried adding this on top but it doesn't work: RewriteCond /etc/httpd/conf/crossdomain/$1.$2.xml -f I guess because it is a chained rule, no idea. Please help.

• Activator.CreateInstance fails in Windows Service

  - by kbe

  I have an issue with a Windows Service which throws a NullReference exception whenever I try to use var myType = Activator.CreateInstance(typeof(MyType)) There is no problem whenever I run the exact same code in a console window - and after debugging the obvious "which user is running this code" I doubt that it is a mere fact of changing the user running the service as I've tried to run the service using the computer's Administrator account as well as LocalSystem. I'm suspecting a Windows Update fiddling with default user rights but that's a bit of a desperate guess I feel. Remember: The type and assembly exist and works fine - otherwise I wouldn't be able to run the code in a console window. It is only when running in the context of a Windows Service I get an error. The question is: Can I in any way impersonate i.e. LocalSystem in a unittest by creating a GenericPrincipal (how would that GenericPrincipal look)?

• How to call an programmatically generated event for wxRadioButton in wxWidgets ?

  - by Jakub Czaplicki

  I am trying to programmatically change a value of a wxRadioButton in a way the user would do it. A value change doesn't call the event corresponded to the button, and it make sense since the documentation says it clearly: wxRadioButton::SetValue void SetValue(const bool value) Sets the radio button to selected or deselected status. This does not cause a wxEVT_COMMAND_RADIOBUTTON_SELECTED event to get emitted. So the question is how can I call an programmatically generated event for a wxRadioButton ? I guess that it's something to do with: wxWindow window->AddPendingEvent(wxEvent *event ) A simple example would be greatly appreciated.

• Drupal setup for proofreaders - "Revision Moderation"

  - by Olav

  I would like to have external proofreaders to work directly inside my Drupal site. Basically they should be able to create new revisions, annotate, comment etc without affecting what users see without my approval. Particularly the node might already be public. "Revision Moderation" module sounds a bit like what I want, but it seems not to be so much used, and I run into other modules like "Workflow". What is important for me: Possibility to work on content already published Easy for the proofreader, easy for me to direct her to the right location Other useful features such as comments (Like those balloons in Word), diffs etc (I guess I could work around (1) by copying the content)
