• Best practice in this situation?

  - by Steve

  My Delphi program relies heavily on Outlook automation. Outlook versions prior to 2007-SP2 tend to get stuck in memory due to badly written addins and badly written Outlook code. If Outlook is stuck, calling CreateOleObject('Outlook.Application') or GetActiveObject ... doesn't return and keeps my application hanging till Outlook.exe is closed in the task manager. I've thought of a solution, but I'm unsure whether it's good practice or not. I'd start Outlook with CreateOleObject in a separate thread, wait 10 seconds in my main thread and if Outlook hangs (CreateOleObject doesn't return), offer the user to kill the Outlook.exe process from my program. But since I don't want to force the user to kill the Outlook.exe proccess, as an alternative I also need a way to kill the new thread in my program which keeps hanging now. My questions are: a, Is this good practice b, How can I terminate a hanging thread in Delphi without leaking memory? Is there a way?

• Gallery items become off-center when switching into landscape orientation.

  - by Sandile

  Hey Guys, Thanks for your time. I'm writing an application for android 2.2 and I'm using a gallery to circulate through a list of images that the user can then click to navigate other portions of the application. In portrait orientation, everything is kosher: the images are displaying correctly (completely in the center of the screen as I intended); however, in landscape orientation, all the images in the gallery are strangely displaced a fixed distance to the left of the center of the screen. I've been researching this issue for hours now and haven't found a solution. I'm hoping that some android guru can aid me in the resolution of this bizarre rendering issue. MainMenuActivity.java relevant code snippet (the activity in which the gallery resides) Gallery optionList = (Gallery)findViewById(R.id.mainMenuOptionList); GalleryItem[] optionListItemIdArray = new GalleryItem[] { new GalleryItem(R.drawable.icon_main_menu_option_list_blackboard, "Start Next Lesson", "Start the next planned vocab lesson."), new GalleryItem(R.drawable.icon_main_menu_option_list_index_cards, "Review Words", "Manually look over old words."), new GalleryItem(R.drawable.icon_main_menu_option_list_dice, "Play Vocab Games", "Play games to reinforce knowledge."), new GalleryItem(R.drawable.icon_main_menu_option_list_calendar, "View Lesson Plan", "View the schedule for coming lessons."), new GalleryItem(R.drawable.icon_main_menu_option_list_pie_chart, "View Performance Report", "Evaluate your overall performance statistics."), new GalleryItem(R.drawable.icon_main_menu_option_list_settings, "Manage Settings", "Change and modify application settings.") }; optionList.setAdapter(new GalleryImageAdapter(this, optionListItemIdArray)); NOTE: A GalleryItem is a POJO with an image resource id, title and description. GalleryImageAdapter.java: public class GalleryImageAdapter extends BaseAdapter { private Context context; private GalleryItem[] galleryItemArray; public GalleryImageAdapter(Context context, GalleryItem[] galleryItemArray) { this.context = context; this.galleryItemArray = galleryItemArray; } @Override public int getCount() { return galleryItemArray.length; } @Override public Object getItem(int position) { return position; } @Override public long getItemId(int position) { return position; } @Override public View getView(int position, View convertView, ViewGroup parent) { ImageView imageView = new ImageView(context); imageView.setImageResource(galleryItemArray[position].getImageId()); imageView.setScaleType(ImageView.ScaleType.FIT_START);

• How to organize a ASP.NET MVC solution (DDD)

  - by vandalo

  Hello everyone. I am trying to start a new project (asp.net MVC) and I would like to apply some DDD rules I've learned in these last few months. I don't know how to organize my solution though. I would like to use Nhibernate but I don't want to use Fluent Nhibernate cause it must be something like an experiment. I've seen some examples where people keep everything in the same project. Some others tend to create a different project for everything. Do you think I should differentiate the model and the repository or put it in the same project? If someone has some links to articles etc it would be appreciated. thanks Alberto

• GUI for Build Process

  - by sarah xia

  Hi All, I've just implemented build and deploy process which consists of java files, ant script and cmd files. In the process, a release manager will have to check out source, hit the build.cmd button and then carry a zip file over to a server. I am wondering if it is worthwhile to make a GUI for it? So that the release manager does not need to check out source manually for example? How do I start? I have quite limited knowledge of javax, but I very much like to learn. Thanks, Sarah

• Waiting for Transformations in a Job

  - by DaDaDom

  I am working with Pentaho Data Integration (aka Kettle) and I have several Transformations, let's call them A, B, C, D, E. B depends on A, D depends on C and E depends on B and D. In a job I'd like to run A, B and C, D in parallel: -> A -> B _ Start< \ -> C -> D----> E where A and C run in parallel. Is there any way to execute E only iff B AND D were successful? Right now, looking at the Job metrics, E gets executed as soon as either B OR D are finished.

• Best Open Source Project Hosting Site

  - by Cristian

  I want to start an open source project, but the rise in hosting sites leaves me a little paralyzed with choice. I know a little about several: I never really liked SourceForge's UI but it still feels like the site I think of when I think "open source project hosting". Google Code Project Hosting looks clean and useful but doesn't seem as feature complete as SourceForge. I've heard good things about Launchpad but don't know much about it nor do I know Bazaar (though I'd be interested in learning it). I know almost nothing about GitHub and, like Bazaar, I don't know Git. Does anyone have any experience with these sites or some other cool code host? Any recommendations?

• Extracting a string starting with x and ending with y

  - by DMan

  First of all, I did a search on this and was able to find how to use something like String.Split() to extract the string based on a condition. I wasn't able to find however, how to extract it based on an ending condition as well. For example, I have a file with links to images: http://i594.photobucket.com/albums/tt27/34/444.jpghttp://i594.photobucket.com/albums/as/asfd/ghjk6.jpg You will notice that all the images start with http:// and end with .jpg. However, .jpg is succeeded by http:// without a space, making this a little more difficult. So basically I'm trying to find a way (Regex?) to extract a string from a string that starts with http:// and ends with .jpg

• Check if a php script is still running

  - by Nirmal

  I have a script that listens to a jabber server and responds accordingly. Though it's not supposed to stop, last night it did. Now I want to run a cron job every minute to check if the script is running, and start it if not. The question is, how do I check if a particular script is still running? Some solutions have been posted here, but those are all for Linux, while I am looking for a Windows solution. Any ideas please? Thanks.

• CodeBlocks, GCC: change project language c and c++?

  - by user394242

  When I select console project to start with, it lets you select c or c++, but once its created.. i can't figure out where to change it, and when you create a win32 gui application, it doesn't give you the option at all, and its default is c++.. where can i change to c? i have been looking in all the project settings for AGES. renaming my file from cpp to .c doesn't seem to do anything, it compiles the file as cpp. i know that without the ide, you just change your exe from g++ to gcc, but how do i set this for the current project in codeblocks?

• getting rid of ruby gems that won't die

  - by holden

  I've got a few ruby gems that won't go away. I think it has to do with when I installed them. Occasionally I have forgotten to use "sudo" before doing a gem install, which results in a write error and from what I can gather puts a copy of the gem in my user directory instead of somewhere it can run. But gem uninstall doesn't work. It continually shows up in 'gem list' but can't uninstall it from either gem uninstall, or sudo gem uninstall. I tried directly deleting one gem after finding the path in my 'gem environment', but that still left the gem on the list. Also is it possible just to remove all gems and start from scratch? These are driving me nuts. I'm running OS X. Thanks,

• Sending and receiving async over multiprocessing.Pipe() in Python

  - by dcolish

  I'm having some issues getting the Pipe.send to work in this code. What I would ultimately like to do is send and receive messages to and from the foreign process while its running in a fork. This is eventually going to be integrated into a pexpect loop for talking to interpreter processes. ` from multiprocessing import Process, Pipe def f(conn): cmd = '' if conn.poll(): cmd = conn.recv() i = 1 i += 1 conn.send([42 + i, cmd, 'hello']) if __name__ == '__main__': parent_conn, child_conn = Pipe() p = Process(target=f, args=(child_conn,)) p.start() from pdb import set_trace; set_trace() while parent_conn.poll(): print parent_conn.recv() # prints "[42, None, 'hello']" parent_conn.send('OHHAI') p.join() `

• How would you go about tackling this problem?

  - by incrediman

  I have a programming contest coming up in about half a week, and I've been prepping :) I found a bunch of questions from this canadian competition, they're great practice: http://cemc.math.uwaterloo.ca/contests/computing/2009/stage2/day1.pdf I'm looking at problem B ("Dinner"). Any idea where to start? I can't really think of anything besides the naive approach (ie. trying all permutations) which would take too long to be a valid answer. Btw, the language there says c++ and pascal I think, but i don't care what language you use - I mean really all I want is a brief description of how to tackle the problem. Like "use X technique treating each programmer as a Y" or something :)

• Create MSI for slipstream SQL 2008 install

  - by Graham

  I am looking at creating an MSI that will check/install the prerequisites of SQL Server 2008 and after the prerequisites are installed I will start my slipstream 2008 install. I am currently trying to do this through VS 2008 Deployment Projects, but I cannot just simple add the folders of the SQL slipstream into the setup project without recreating the entire folder structure of the SQL install. So my questions are: Is this a possible to do through Deployment Projects? (if yes, please assist with links or help) Is there a better way to do this? (I would prefer not to use WISE)

• How does glClear() improve performance?

  - by Jon-Eric

  Apple's Technical Q&A on addressing flickering (QA1650) includes the following paragraph. (Emphasis mine.) You must provide a color to every pixel on the screen. At the beginning of your drawing code, it is a good idea to use glClear() to initialize the color buffer. A full-screen clear of each of your color, depth, and stencil buffers (if you're using them) at the start of a frame can also generally improve your application's performance. On other platforms, I've always found it to be an optimization to not clear the color buffer if you're going to draw to every pixel. (Why waste time filling the color buffer if you're just going to overwrite that clear color?) How can a call to glClear() improve performance?

• Calling AS3 function from html link - Javascript? php? swfaddress?

  - by wdense51

  I have an actionscript function that loads an external swf and is currently linked to a button in the same swf... function btnClick(event:MouseEvent):void{ SoundMixer.stopAll(); removeChild(loader); loader.contentLoaderInfo.addEventListener(Event.COMPLETE, onSWFLoaded); loader.load(movieSWF) loader.x=Xpos loader.y=Ypos addChild(loader) } button.addEventListener(MouseEvent.CLICK,btnClick); I'm wondering if there is a way to call this function from a link on the page that the swf is housed on. I'm guessing javascript, php or swfaddress would be the most likely way, but I'm unbelievably new to all this so I'm not sure where to start or how to go about it. Any help would be appreciated.

• WinForms equivalent of performSelectorOnMainThread in Objective-C

  - by jamone

  I haven't done much multithreading before and now find the need to do some background work and keep the UI responsive. I have the following code. data.ImportProgressChanged += new DataAccess.ImportDelegate(data_ImportProgressChanged); Thread importThread = new Thread( new ThreadStart(data.ImportPeopleFromFAD)); importThread.IsBackground = true; importThread.Start(); void data_ImportProgressChanged(int progress) { toolStripProgressBar.Value = progress; } //In my data object I have public void ImportPeopleFromFAD() { ImportProgressChanged(someInt); } But the UI doesn't get updated since the ImportProgressChanged() call is made on the background thread. In objective C I know you can use performSelectorOnMainThread and pass it a method to call using the main thread. What is the equivalent way of calling ImportProgressChanged() from the main thread?

• OpenMP timer doesn't work on inline assembly code?

  - by Brett

  I'm trying to compare some code samples for speed, and I decided to use the OpenMP timer since I'll eventually be multi threading the code. The timer works great on two of my four code snippets, but not on the other two start=omp_get_wtime(); /*code here*/ finish = omp_get_wtime() - start_time; The four code here sections are serial code, xmmintrin.h code, and two inline assembly codes. The serial and xmminstrin.h code are able to be timed, but the inline assembly codes returns -1.#IND00 for a time. I can't seem to figure out why this is? Thanks for any help or suggestions!

• What's the cleanest way to programmatically kill and restart explorer.exe?

  - by Paul Accisano

  Greetings all, I'm working on a Windows program whose installation necessitates restarting explorer.exe. I know "Reboot your computer to complete the installation" is the standard method here, but I'd like my installer to give users the option of just restarting Explorer so they can start using my program immediately. What's the best way to do that? Of course I could just find and kill the process, but that seems rather icky. Is there some trick to, say, make Explorer think the user is logging off and close cleanly? Thanks!

• Can the Windows Media Player COM control play AVI files from memory (instead of from a file)?

  - by MusiGenesis

  I have a C# app, and I'm looking at using the Windows Media Player COM control to play animation and audio. So far, the only way I see of programatically controlling what the control is playing is to set its URL property to point to some file (I assume there's some way to pass in a playlist). Is there any way the WMP can render an AVI that is entirely in-memory, like a MemoryStream or something? If so, can WMP skip from one AVI to the next seamlessly (i.e. no glitch in either the audio or the video as it transitions from one to the next)? If WMP only plays files, is there some way to cue up a list of the files in advance of play start? If so, can WMP be made to skip from one file to the next without a brief interruption? Any knowledge or links to knowledge would be much appreciated.

• iPhone: Grouped Table Confusion

  - by senfo

  I'm trying to follow along with this UITableView tutorial and I'm afraid I'm getting confused. What I hope to accomplish is to create a grouped table, which resembles the look and feel of the following image (image source): For each "break" in the table, I assume that I need another section. I understand there is a global NSMutableArray, which acts as the data source to the UITableView. Inside this global array, there are dictionaries for sections and for data, but this is where I start getting confused. Should I create a unique table to store each section in addition to a new table for the rows that are part of that section? In other words, if I have five sections, will I end up with ten unique collections of data (one for each section and one to store the rows related to the section), which all eventually get stored in the global array?

• PyQt: Get the position of QGraphicsWidgets in a QGraphicsGridLayout

  - by Chris Phillips

  I have a fairly simple PyQt application in which I'm placing instances of a QGraphicsWidget in a QGraphicsGridLayout and want to connect the widgets with lines drawn with a QGraphicsPath. Unfortunately, no matter what I try, I always get (0, 0) back as the position for both the start and end widgets. I'm constructing the graph with a recursive function that adds widgets to the scene and layout. Once the recursive function is complete, the layout is added to a new widget, which is added to the scene to show everything. The edges are added to the scene as widgets are created. How do I get a non-zero position of any of the widgets in the grid layout?

• Which OOD approach should I take?

  - by Sorush Rabiee

  According to Niklaus Wirth, Algorithms + Data Structures = Programs. So I use this as a start point to object-oriented modeling and inheritance design: in a way that I separate the 'Objects' from 'Operations'. then look for patterns and inheritance hierarchy. But now after practice I guess it's not a good idea for every modeling problem, because sometimes it's not effective. (I mean there is no possibility of developing (or is very hard to develop) codes of Turing-Completed languages based on this paradigm.) What is your viewpoint for designing an OOD structure as an experienced programmer?
