• eclise java internal webbrowser progress listener?

  - by deepthinker121

  Hi All, I need to open an internal web browser from a custom eclipse wizard I have created - and so I am using IWebBrowser webBrowser = browser.createBrowser (IWorkbenchBrowserSupport.LOCATION_BAR | IWorkbenchBrowserSupport.AS_EDITOR | IWorkbenchBrowserSupport.NAVIGATION_BAR | IWorkbenchBrowserSupport.STATUS, null,"TestBrowser", "TestBrowser"); URL url = new URL("http://localhost:8080/app"); webBrowser.openURL(url); Now the problem is - the openURL needs time to complete as it tries to load a page for a webapp and as I am not able to get the progress of the 'load page' operation of the URL - my wizard progressmonitor completes before the URL can be completely loaded . Is there any way to get the status of the page load operation - (to check if its complete or it failed) or add a listener to indicate completion of page load? It is okay for me to use some other implementations of internal web browsers - so please suggest some other approach we cannot add a listener to IWebBrowser.. Thanks for ur help !!

• How can I programmatically read a Adobe DRM'd Epub?

  - by DEzra

  I am writing an ebook reader that supports the epub format (i have the parsing of open epub working), but I would like to support the reading of Adobe DRM locked epubs. I have read through the Adobe digital editions site (faq and support pages) and googled, but alas as yet I have not found any docs on the API to: authorise the PC using the user's Adobe ID credentials and decrypt the epub for parsing by my app. Does anyone have any pointers to docs or APIs? I would prefer APIs in Python, C++. But any API is better than nothing ;-) UPDATE1: I am writing my app on Desktops (linux, mac and windows). UPDATE2: Just to be clear, I am assuming that user has paid for the book legitimately and so does have an Adobe ID. I don't want to crack the DRM, just allow the user to read their books that they bought.

• Office Automation Libraries

  - by Ian

  Some time ago I posted about a question about reading Excel files as a server process, to get around the tighter restrictions Microsoft have been applying on Office Automation. I now need to extend this, by finding methods/libraries to read other sorts of Office files in an automated way on a server. The applications I'm interested in are Word, Powerpoint, Project and to a lesser extent Word and Visio. I need to be able to support 97-2003 office files, and the newer open xml formats (e.g. xlsx, docx) at a very least. With regards to Word integration, I also need to be able to handle writing/reading RTF text. If anyone has any suggestions I'd be pleased to hear them. Thanks

• Connecting to multiple firebird Databases via Delphi

  - by Branden

  I am integrating a system with 2 other applications, 1 using a Firebird database whilst the other BIS (using ADO). My delphi application uses Firebird. I need to read data from my database, insert it into both the BIS database and the other application firebird database. I have created seperate data modules for each. Sending data to the ADO works fine, but when writing to the other Firebird DB (my db still open) I get strange errors. I have managed to isolate the problem to the second firebird DB. Small data writes seems fine. The data structures are completly different, so un able to use a synch tool. is there a way to overcome this by using multi threading or seperate memory space each Firebird instance uses?

• Android application chrashes after "share" intent

  - by Johe Green

  Hi, My app offers a "share/tell-a-friend" function. When the "share" button is pressed the following method is being called to open a list of apps, which can perform the action (Eg. Gmail, Twittroid, Facebook...): public void share() { Intent shareIntent = new Intent(android.content.Intent.ACTION_SEND); shareIntent.setType("text/plain"); shareIntent.putExtra(android.content.Intent.EXTRA_SUBJECT, getText(R.string.menu_share_subject)); shareIntent.putExtra(android.content.Intent.EXTRA_TEXT, getText(R.string.menu_share_body)); startActivity(Intent.createChooser(shareIntent, getText(R.string.menu_share_intent))); } The sharing functionality works basically. But when the sharing app (Facebook, Twitter, ...) tries to return to my app, a force close is thrown. I guess that my app gets closed in the background during the sharing process... at least that is what the debugger sais... Any ideas?

• How to write program to do file transfer based on based omniORBpy

  - by cofthew7

  I'm now writing a Corba project to do file transfering between client and server. But I face trouble when I want to upload file from the client to the server. The IDL I defined is: interface SecretMessage { string send_file(in string file_name, in string file_obj); }; And I implemented the uploading function in the client code: f = open('SB.docx', 'rb') data = '' for piece in read_in_chunks(f): data += piece result = mo.send_file('2.docx', data) If the file is a plain txt file, there is no problem. But if the file is a, like jpg, doc, or others except txt, then it does work. It gives me the error: omniORB.CORBA.BAD_PARAM: CORBA.BAD_PARAM(omniORB.BAD_PARAM_WrongPythonType, CORBA.COMPLETED_NO) Where is the problem?

• Why isn't wchar_t widely used in code for Linux / related platforms?

  - by Ninefingers

  This intrigues me, so I'm going to ask - for what reason is wchar_t not used so widely on Linux/Linux-like systems as it is on Windows? Specifically, the Windows API uses wchar_t internally whereas I believe Linux does not and this is reflected in a number of open source packages using char types. My understanding is that given a character c which requires multiple bytes to represent it, then in a char[] form c is split over several parts of char* whereas it forms a single unit in wchar_t[]. Is it not easier, then, to use wchar_t always? Have I missed a technical reason that negates this difference? Or is it just an adoption problem?

• wx Menu disappears from frame when shown as a popup

  - by Adam Fraser

  I'm trying to create a wx.Menu that will be shared between a popup (called on right-click), and a sub menu accessible from the frame menubar. The following code demonstrates the problem. If you open the "MENUsubmenu" from the menubar the item "asdf" is visible. If you right click on the frame content area, "asdf" will be visible from there as well... however, returning to the menubar, you will find that "MENUsubmenu" is vacant. Why is this happening and how can I fix it? import wx app = wx.PySimpleApp() m = wx.Menu() m.Append(-1, 'asdf') def show_popup(evt): ''' R-click callback ''' f.PopupMenu(m, (evt.X, evt.Y)) f = wx.Frame(None) f.SetMenuBar(wx.MenuBar()) frame_menu = wx.Menu() f.MenuBar.Append(frame_menu, 'MENU') frame_menu.AppendMenu(-1,'submenu', m) f.Show() f.Bind(wx.EVT_RIGHT_DOWN, show_popup) app.MainLoop() Interestingly, appending the menu to MenuBar works, but is not the behavior I want: import wx app = wx.PySimpleApp() m = wx.Menu() m.Append(-1, 'asdf') def show_popup(evt): f.PopupMenu(m, (evt.X, evt.Y)) f = wx.Frame(None) f.SetMenuBar(wx.MenuBar()) f.MenuBar.Append(m, 'MENU') f.Show() f.Bind(wx.EVT_RIGHT_DOWN, show_popup) app.MainLoop()

• ASP.NET Deployment under IIS7/VS2010 as Web Application

  - by adchased

  I transformed my VS2008 ASP.NET Website to a "Web Application" today using VS2010. So now it's possible to build a Deployment Package. A Zip Package which can be direclty imported into IIS7. Usually I added a website in IIS7 called mydomain.com and put everything in its root dir. That worked. However, since I converted to an Web Application, this Application is added beneath my "Website container". Now I'm confused, this is how it actually looks now when I try to open the website: Browsing to mydomain.com says 404 ERROR. Browsing to mydomain.com/mydomain.com opens the actual website, but in a subfolder instead of the root directory. (The Application is named after the Domain) How to make this application the root of the website now? I want the application to run under the mydomain.com ROOT and not some subfolder. Thanks a lot!

• Getting help on MATLAB's com.mathworks internals

  - by Richie Cotton

  It is possible to access bits of MATLAB's internal java code to programmatically change MATLAB itself. For example, you can programmatically open a document in the editor using editorServices = com.mathworks.mlservices.MLEditorServices; editorServices.newDocument() %older versions of MATLAB seem to use new() You can see the method signatures (but not what they do) using viewmethods. viewmethods(com.mathworks.mlservices.MLEditorServices) I have a few related questions about using these Java methods. Firstly, is there any documentation on these things (either from the Mathworks or otherwise)? Secondly, how do you find out what methods are available? The ones I've come across appear to be contained in JAR files in matlabroot\java\jar, but I'm not sure what the best way to inspect a JAR file is. Thirdly, are there functions for inspecting the classes, other than viewmethods? Finally, are there any really useful methods that anyone has found?

• Does Objective-C have a Standard Library?

  - by Roman A. Taycher

  Most somewhat modern programming languages have a standard library? It is my impression is that there isn't a decent sized standard library for Obj-C , rather that it relies mostly/all on Cocoa and that (plus people not wanting to use GNUstep) is why Obj-C is only used on macs)? Is this true/to what extent? Are there any standard obj-c collections? (note I haven't done any Obj-C programming and am not to likely to try it in the near future, I'm just curious). P.S. are there a any decent non-Cocoa/Gnustep Libraries? are they non-apple, are they open source, well documented?

• What can I use for voluntary donations? (like Tipjoy)

  - by Ken

  There used to be a site called Tipjoy that would let me put a small "donate" button on a webpage, and users could donate small amounts (like 25c) to me easily. I think it was a pretty neat idea, since I want to have a way for people to give me money, and I don't like advertisements, and I don't update regularly enough to sell subscriptions like bloggers. I just have some simple web services and open-source program and I want an easy way for people to drop me some change if they think they're useful. I've found out that Amazon used to have a similar service, but it's also been shut down. Is there any similar web service available today? If not, what's the closest thing to offer -- a Paypal link?

• Stream a file to the HTTP response in Pylons

  - by Evgeny

  I have a Pylons controller action that needs to return a file to the client. (The file is outside the web root, so I can't just link directly to it.) The simplest way is, of course, this: with open(filepath, 'rb') as f: response.write(f.read()) That works, but it's obviously inefficient for large files. What's the best way to do this? I haven't been able to find any convenient methods in Pylons to stream the contents of the file. Do I really have to write the code to read a chunk at a time myself from scratch?

• Animated Gif in form using C#

  - by Rabin

  In my project, whenever a long process in being executed, a small form is displayed with a small animated gif file. I used this.Show() to open the form and this.Close() to close the form. Following is the code that I use. public partial class PlzWaitMessage : Form { public PlzWaitMessage() { InitializeComponent(); } public void ShowSpalshSceen() { this.Show(); Application.DoEvents(); } public void CloseSpalshScreen() { this.Close(); } } When the form opens, the image file do not immediately start animating. And when it does animate, the process is usually complete or very near completion which renders the animation useless. Is there a way I can have the gif animate as soon as I load the form?

• 503 (Server Unavailable) WebException when loading local XHTML file

  - by kcoppock

  Hello! So I'm currently working on an ePub reader application, and I've been reading through a bunch of regular XML files just fine with System.Xml and XmlDocument: XmlDocument xmldoc = new XmlDocument(); xmldoc.Load(Path.Combine(Directory.GetCurrentDirectory(), "META-INF/container.xml")); XmlNodeList xnl = xmldoc.GetElementsByTagName("rootfile"); However, now I'm trying to open the XHTML files that contain the actual book text, and they're XHTML files. Now I don't really know the difference between the two, but I'm getting the following error with this code (in the same document, using the same XmlDocument and XmlNodeList variable) xmldoc.Load(Path.Combine(Directory.GetCurrentDirectory(), "OEBPS/part1.xhtml")); "WebException was unhandled: The remote server returned an error: (503) Server Unavailable" It's a local document, so I'm not understanding why it's giving this error? Any help would be greatly appreciated. :) I've got the full source code here if it helps: http://drop.io/epubtest (I know the ePubConstructor.ParseDocument() method is horribly messy, I'm just trying to get it working at the moment before I split it into classes)

• Visual C# | Capturing data from a window in a closed-source third-party Win32 application

  - by Zach Albia

  I'm planning on creating a C# Windows Forms app as an extension for a third-party Win32 application but I'm stumped as to how to do this right now. The farthest I've gotten is knowing it involves Win32 Hooking and that there's this open source project called EasyHook that's supposed to allow me to do this. I'd like to know how I can get the text from a textbox or some other data from a control in a third-party Win32 application. The text/data in a control is to be captured from the external application's running window the moment the user presses a button. I guess the question can be summed up as follows: How do you determine the event to hook to when the user clicks a certain button? How do you get the value displayed by a Win32 control at the time the button is clicked?

• How to recognise vehicle licence / number plate (ANPR) from an image?

  - by Ryan ONeill

  Hi all, I have a web site that allows users to upload images of cars and I would like to put a privacy filter in place to detect registration plates on the vehicle and blur them. The blurring is not a problem but is there a library or component (open source preferred) that will help with finding a licence within a photo? Caveats; I know nothing is perfect and image recognition of this type will provide false positive and negatives. I appreciate that we could ask the user to select the area to blur and we will do this as well, but the question is specifically about finding that data programmatically; so answers such as 'get a person to check every image' is not helpful. This software method is called 'Automatic Number Plate Recognition' in the UK but I cannot see any implementations of it as libraries. Any language is great although .Net is preferred. Thanks in advance Ryan

• Ubuntu: SWT App Can't Load GTK Library

  - by Nifty255

  I have supplied the Linux SWT jar and packaged my app in Eclipse to include swt.jar inside my app's jar. When I try to run it on Ubuntu, I get the following error text (posting only cause): Caused by: java.lang.UnsatisfiedLinkError: Could not load SWT library. Reasons: no swt-pi-gtk-4234 in java.library.path no swt-pi-gtk in java.library.path /home/nifty/.swt/lib/linux/x86/libswt-pi-gtk-4234.so: libgtk-x11-2.0.so.0: cannot open shared object file: No such file or directory Can't load library: /home/nifty/.swt/lib/linux/x86/libswt-pi-gtk.so This indicates to me it can't load a GTK file, but anything beyond that, and I'm at a loss. I'm only using Ubuntu to test my app, so I know very little.

• What is it that automatically checks config changes (such as those in /etc) into git?

  - by Brandon

  I remember reading on the ubuntu forums some time ago about a program to automatically check configuration changes into version control for you. It was (of course) not Ubuntu-specific. I'm pretty sure it used git, though it may have been svn, or perhaps even able to work with multiple different VCSs. My Googling has turned up nothing, and I'd rather not roll my own script if someone has already done this well. Of course I could just manually check things in, but there are reasons I'd like it done automatically. (I'm actually planning to use this for my LastSession.plist file for Safari, so when the #@$%^*&! thing crashes, and I don't restore everything, and then Leopard crashes, the fact that it has such lousy session management won't mean I lose the dozens of windows with dozens of tabs I had open.)
