• PDF reader to capture regions

  - by Amitesh

  I need to build an application which can render a pdf document. The application should allow the user to draw rectangles on the pdf to define regions such as Address region, Invoice Number region and so on. The application will need to capture these regions and save them. I already have an application in which I can pass these region information with the pdf and it will get me the text back. My only problem at the moment is that I cannot get the region information from the user. So can anybody please point me to any application which can do the above (allow the user to draw rectangles to capture the regions).

• "Othello" game needs some clarification

  - by pappu

  I am trying to see if my understanding of "othello" fame is correct or not. According to the rules, we flip the dark/light sides if we get some sequence like X000X = XXXXX. The question I have is if in the process of flipping 0-X or X- 0, do we also need to consider the rows/columns/diagonals of newly flipped elements? e.g. consider board state as shown in above image(New element X is placed @ 2,3) When we update board, we mark elements from 2,3 to 6,3 as Xs but in this process elements like horizontal 4,3 to 4,5 and diagonal 2,3 to 4,5 are also eligible for update? so do we update those elements as well? or just the elements which have starting as 2,3 (i.e update rows/column/diagonal whose starting point is the element we are dealing with, in our case 2,3?) Please help me understand it

• Array with mutiple types?

  - by aleluja

  Hello, I was wondering if there is a way to make an array which would have mutiple types of data fields. So far i was using aMyArray: array of array [0..1] of TPoint; But now, it is not enough for me. I need to add 3 more elements to the existing 2 "Point" elements making it an array like aMyArray: array of (TPoint,TPoint,real,real,real) So each element of aMyArray would have 5 'children', 2 of which are of a TPoint type and 3 of them are 'real' type. Is this possible to implement somehow?

• How do I fix my VM's network connection if it seems to be running ok from the host?

  - by AndreiC

  I have a virtual machine (made with vmware) with a linux ubuntu os installed on it (i have a series of them), with NAT network connection - i am running vmware on Windows XP (my host system); the virtual machine can't connect to the internet. All the vmware services seem to be working fine from windows point of view, but inside the machine i can't connect to the internet. What is strange is that the virtual machine was able to use the internet some time ago, but all of a sudden, i just can't use my internet on the virtual machine - i have made no changes to the settings, nor in windows, nor in the virtual machine - so i don't understand.

• Do (statically linked) DLLs use a different heap than the main program?

  - by happy_emi

  I'm new to Windows programming and I've just "lost" two hours hunting a bug which everyone seems aware of: you cannot create an object on the heap in a DLL and destroy it in another DLL (or in the main program). I'm almost sure that on Linux/Unix this is NOT the case (if it is, please say it, but I'm pretty sure I did that thousands of times without problems...). At this point I have a couple of questions: 1) Do statically linked DLLs use a different heap than the main program? 2) Is the statically linked DLL mapped in the same process space of the main program? (I'm quite sure the answer here is a big YES otherwise it wouldn't make sense passing pointers from a function in the main program to a function in a DLL). I'm talking about plain/regular DLL, not COM/ATL services EDIT: By "statically linked" I mean that I don't use LoadLibrary to load the DLL but I link with the stub library

• Visual Studio build and deploy ordering

  - by mthornal

  We have a VS 2010 solution that includes a few class library projects, a SQL Server 2008 database project and a Wix setup project. We are trying to get to a point where the following happens in the order specified: Build the class library projects and the database project Deploy the database project to generate the deploy .sql script Build the Wix setup project. The reason for the desired order is that the setup project requires the deployment .sql scripts as it will use these to generate/update the database on the machine that the msi is run. It seems that there is no way within a Visual Studio solution file to create this type of build/deploy/build order. Is this correct? Thanks

• How the existing data to be if entity structure modified or deleted on GAE?

  - by Eonil

  GAE recommends using JDO/JPA. But I have serious question about using OODB like them. JDO based on user's class structure. And data structure should be modified continually as service advances. So, If data(entity) class property being removed, what happened to existing data on the property? If data(entity) class renamed for refactoring reason, how the JDO know those renaming? Or all data loss? Major point is "How JDO/GAE/BigTable applies modification of class into existing entity structure and data?".

• Java: Looking for hack to deal with Windows file paths in Linux

  - by Chase Seibert

  Say you have a large legacy ColdFusion on top of Java on Windows application. File access is done both via java.io.File and by CFFILE (which in turn also uses java.io.File), but not centralised in any way into a single file access library. Further, say you have file paths both hard-coded in the code, and also in a database. In other words, assume the file paths themselves cannot change. They could be either local or remote Windows file paths: c:\temp\file.txt \\server\share\file.txt Is there a way to run this application on Linux with minimal code changes? I'm looking for creative solutions that do not involve touching the legacy code. Some ideas: Run it on WINE. This actually works, because WINE will translate the local paths, and has a samba client for the remote paths. Is there a way to override java.io.File to perform the file path translation with custom code? In this case, I would translate the remote paths to a mount point.

• Invalidating UITableView contents

  - by Roman

  I have an application with several UITableViewControllers. Now, the user is allowed to change "Data source". In that case I need to invalidate (reset) data in the relevant UITableViews. I figured out, that I can use NSNotificationCenter and add these controllers as observers to events which will be generated when the data source changes. The question is, how do I reset the underlying tables? I can, of course, set some boolean flag, and call UITableView:reloadData in viewWillAppear or viewDidAppear, but I was wondering, if there's a cleaner way of doing it. Or perhaps I'm completely missing the point, and I don't need NSNotificationCenter altogether. Thank you very much in advance.

• Rails passenger production cache definition

  - by mark

  Hi I'm having a bit of a problem with storing data in rails cache under production. What I currently have is this, though I have been trying to work this out for hours already: #production.rb config.cache_store = :mem_cache_store if defined?(PhusionPassenger) PhusionPassenger.on_event(:starting_worker_process) do |forked| if forked Rails.cache.instance_variable_get(:@data).reset end end end I am using a cron job to (try to) save remote data to the cache for display. It is logged as being written to the cache but reportedly null. If anyone could point me toward a decent current tutorial on the subject or offer guidance I'd be extremely grateful. This is really, really frustrating me. :(

• How to read system information in C++ on Windows and Linux?

  - by f4

  I need to read system information like CPU/RAM/disks usage in C++. Maybe swap, network and process too but that's less important. It has probably been done thousand of times before so I first tried to search for a library. Someone here suggested SIGAR, which seems to fit my needs but it has a GPL license and it is for inclusion in a proprietary product. So it's not an option here. I feel like it's something not that easy to implement, as it'll need testing on several platforms. So a library would be welcome. If you don't know of any library, could you point me in the right direction for both platforms?

• Information stored in a cookie file

  - by jklmuk

  Thanks for you help in advance. I am trying to figure out the structure of the cookie file, more specifically i want to be able to determine the expiry time. From the cookies i have created they all appear to be in a standard format. Name, Value, website,followed by 5 numbers and a star. See example below. name value www.website.co.uk/ 1536 3041141504 30135951 1632526096 30135949 * Obviously the expiry time is one of the numbers, the question is which one. From experiments I have determined that the first and fifth number don't seem to change. In a case where i generated three cookies at the same time with a 1000 second time difference i noticed that the fourth number appeared to increase by 2000 suggesting that this has a connection with the expiry time. Can anyone confirm if i am heading in the right direction? And does any one know how i convert this to a human time and date(preferably in php but any language would give me a starting point) thanks Jason

• UIScrollView with over 100 images

  - by tikkips

  I have implemented a UIScrollView on the iPhone that contains 100 image slots which I fill only the currently visible page, the one before it, and the one after it as the user scrolls. Everything works fine until we get up to image 97 or 98, the entire view disappears! The only thing I can do at that point is navigate back to the previous view. Nothing works as far as the scroll view after this. I am not receiving any memory warnings an the rest of the app functions fine. Any ideas? Has anyone created a UIScrollView in paging mode with over 100 pages? Rick

• How to set Camera View as background with views over it?

  - by Android Student

  So, I'm trying to make the background to one of my apps look "futuristic." I thought of an idea to make the screen look almost transparent yet have views over it. So, it would look something like this: I'm thinking that I can use the camera to capture the background of the phone (without taking a picture, just having the real time view in the background) and then, if possible, place a semi-transparent slightly blurred ImageView over that. Finally, on top of that I can place the other views including the ImageButtons. So, my question is how would I go about doing this? I have searched but haven't found anything relevant. It must be possible; its just how to do it? I don't expect you to give me all the code as an answer, just if you have any ideas that can help or links or code that can point me in the right direction, it would be greatly appreciated! Thanks!

• Prevent Java from parsing the command line parameters

  - by User1

  Would like to make anapplication in Java that will not automatically parse parameters used on the command-line. Currently, java requires public static void main(string[]) as the entry point signature. I would like just a single string that I parse myself. Can this be done at all? Here's an example: java MyProgram.class Hello World I would want it to give me Hello World without requiring quotes around that string. I would even settle for java giving me the entire java MyProgram.class Hello World. I'm thinking this is something beyond Java and has more to do with the shell.

• How to change the size of NSImageView control from within program?

  - by Adam

  The following line of code displays an image on my application window, within an NSImageView control named outputImageView. I used Interface Builder to put the NSImageView control onto the window, initially (then bound it to outputImageView). How do I change the size of the NSImageView control within my program, so that it matches the size of the actual image I am displaying (which may change, periodically)? And what if I wanted to change the anchor point for the image (i.e., centered, left edge, bottom right, or whatever? Thanks in advance! [outputImageView setImage: outputImage];

• Can one extract model fit parameters after a ggplot stat_smooth call?

  - by Alex Holcombe

  Using stat_smooth, I can fit models to data. E.g. g=ggplot(tips,aes(x=tip,y=as.numeric(unclass(factor(tips$sex))-1))) +facet_grid(time~.) g=g+ stat_summary(fun.y=mean,geom="point") g=g+ stat_smooth(method="glm", family="binomial") I would like to know the coefficients of the glm binomial fits. I could re-do the fit with dlply and get the coefficients with ldply, but I'd like to avoid such duplication. Calling str(g) reveals the hierarchy of objects that ggplot creates, perhaps there's some way to get to the coefficients through that?

• Rscript does not recognize setGeneric function

  - by Branko K.

  I am trying to convert an R script into something that a client can run in batch mode. My code uses generic functions and one snippet which is near the beginning goes like: setGeneric("testInput", function(inputData, params = list()) standardGeneric("testInput")) I've been using R CMD BATCH and it works fine. However I couldn't find an easy way to make my script print the output on the console, so based on that (and suggestion that Rscript.exe is the "proper" way to run R batch files) I decided to switch to Rscript. However when running the very same .R file with Rscript I get the following: Error: could not find function "setGeneric" Execution halted I know there is probably a trivial reason behind this but I just cannot figure it out. Can someone please point me to where the mistake is? Thanks so much in advance. Cheers!

• openCV center of image rotation in C

  I want to rotate 90 degrees counterclockwise, but it seems the rotation point is wrong. How do I find the rotation center of the source image? img=cvLoadImage(argv[1],-1); height = img->height; width = img->width; step = img->widthStep; channels = img->nChannels; data = (uchar *)img->imageData; IplImage *rotatedImg = cvCreateImage(cvSize(height,width), IPL_DEPTH_8U,img->nChannels); CvPoint2D32f center; center.x = width/2; center.y = height/2; CvMat *mapMatrix = cvCreateMat( 2, 3, CV_32FC1 ); cv2DRotationMatrix(center, 90, 1.0, mapMatrix); cvWarpAffine(img, rotatedImg, mapMatrix, CV_INTER_LINEAR + CV_WARP_FILL_OUTLIERS, cvScalarAll(0)); cvShowImage("My image", rotatedImg );

• Best way to validate currency input?

  - by Abe Miessler

  I have created the TextBox and CompareValidator below which I thought would allow input in the following forms: 5 5.00 $5.00 Unfortunately it's not allowing the version with the dollar sign in it. What is the point of doing a type check against currency if you don't allow the dollar sign? Is there a way to allow this symbol? <asp:TextBox ID="tb_CostShare" runat="server" Text='<%# Eval("CostShare", "{0:$0.00}")%>' CausesValidation="true" /> <asp:CompareValidator ID="vld_CostShare" runat="server" ControlToValidate="tb_CostShare" Operator="DataTypeCheck" Type="Currency" ValidationGroup="vld" ErrorMessage="You must enter a dollar amount for 'Cost Share'." />

• font from psd file for web page

  - by fablife

  I recently took on a project to build a webpage. I am an experienced developer but never worked with coding a psd file into a webpage. Now, the psd file uses a specific font, which I do not have probably, as I can see it in grey and [ ] at the bottom of the fonts list. Sorry for the naive question, but what am I supposed to do from the client's point of view? Should I have that font? Should I buy it? Can I extract it from the psd file? And then, does it come into the web-page as @font-face? Thanks for any suggestion

• Automatic images translation to 3d model

  - by farrakhov-bulat

  I'm quite interested in automatic images translation to 3d models. Not really for commercial product, but from the point of possible academic research and implementation. What I'd like to achieve is almost transparent for user process of transformation series of images (fewer is better) to 3d model which might be shown in flash/silverlight/javafx or similar. Consider online furniture store with 3d models of all items in stock. Kinda cool to have ability to see the product in 3d before purchasing it. I managed to find a few pieces of software, like insight3d, but it couldn't be used in my case I guess. So, are there any similar projects or tips for me? If it would require to write that piece of software - I'd really love to dig into research on this field.

• How would I write a virtual CD/DVD burner that would allow programs that burn to write to ISO?

  - by Ryan

  I want to write an app that will allow a program like iTunes which normally will recognize a DVD/CD burner to recognize a virtual one and then write to it creating an ISO. I would guess to use C/C++... can someone point me in the right direction as to how this can be done? Basically it would be a virtual CD/DVD burner that would output an ISO file to the hard drive. I want to do this for both the usefulness of it as well as the challenge, just need an idea of how to approach it, have no idea how to write virtual hardware.
