• Dynamic size canvas with Scroll bars

  - by Pawan

  Hi, I am developing a simple WPF application without any auto layout. The goal is when a user clicks (mouse down) a element (say textBlock) will appear at the location of the mouse click. For this I am using canvas panel embedded in a Grid of 1 row, 1 column and scrollviewer (visible). The issues are: 1. when the application window is resized the scroll viewers do not become active. 2. I want the ability to auto grow the canvas with mouse drag. Something like in MS-Excel when user drags the mouse horizontally/vertically the canvas should grow. I have searched net a lot to figure this out and am unable to get an answer. Any help in this regard would be great. Thanks a bunch in advance. -P

• How to convert thousands of PDF files to a single Postscript file in a specified order

  - by tggagne

  I've discovered multiple options for convert a few to serveral PDFs into Postscript, but many are command-line programs with command-line limitations (this application lives on .NET). Our application generates tens-of-thousands of PDFs that we need to send to a printer, except BEFORE the Postscript is printed we need to edit the Postscript to insert print command instructions (duplex, tray-pulls, highlight color, etc.) I think a perfect solution might allow us to write the PDFs to a stream, and simultaneously allow us to read the output stream so we may edit the Postscript before writing it to a file. Of course, if I must create the file first containing all 10,000 PDFs and edit it in an additional pass, I'm OK with that, too. I should mention that speed is important. I need to print 10,000 at a time, but need to keep the printers busy 24-hours/day.

• How/is data shared between fastCGI processes?

  - by Josh the Goods

  I've written a simple perl script that I'm running via fastCGI on Apache. The application loads a set of XML data files which are used to lookup values based upon the the query parameters of an incoming request. As I understand it, if I want to increase the amount of concurrent requests my application can handle I need to allow fastCGI to spawn multiple processes. Will each of these processes have to hold duplicate copies of the XML data in memory? Is there a way to set things up so that I can have one copy of the XML data loaded in memory while increasing the capacity to handle concurrent requests?

• a better way to initialize database ONCE when rail server starts

  - by Hadi

  i would like to initialize database the first time the server is started, that involve calling a class method. Given the class name is: Product At first i put an .rb file config\initializers\init.rb as it gets automatically called. Everything works ok, until the database is deleted, and i am trying to do rake db:migrate. rake db:migrate fails saying that cannot find 'product' table. inside init.rb = Product.populate_db The solution i came up is: I took out init.rb do rake db:migrate put back init.rb run the server. My rails application is mainly for reporting and the data is seeded from other application, so i have to do the above step everyday Is there a better way to do the initialization?

• AJAX with Web services and ASP.NET SessionState

  - by needhelp1

  We have an application which uses ScriptManager to generate a client-side proxy which makes AJAX calls to web services. The web services being invoked live in a separate appDomain(separate cluster altogether). The problem is that our application uses a State server for storing session. I want the web services to be able to access session also. First off, does anyone see anything wrong with the client making web service calls to a separate cluster(we're hoping this would be a better approach for scalability)? I was thinking that possibly anytime there is an update to the session dictionary in one appDomain, automatically update the session in the other appDomain also(referring to the web service appDomain, don't know how to do this, only theoretical). What do others think? Thanks!

• How to use @PersistentCapable annotation in Scala 2.8

  - by Gero

  Hi, I'm switching from Scala 2.7.7 to Scala 2.8.0RC3 and now a few of my classes don't compile anymore. The problem is in the @PersistentCapable annotation: import javax.jdo.annotations._ import java.util.Date @PersistenceCapable{identityType=IdentityType.APPLICATION} class Counter(dt: Date, cName: String, vl: int) { <.. snip ..> } This code results in the following compilation errors: [ERROR] /Users/gero/prive/kiva/kivanotify-gae/src/main/scala/net/vermaas/kivanotify/model/LoanProcessed.scala:7: error: expected start of definition [INFO] @PersistenceCapable{val identityType = IdentityType.APPLICATION} I already tried a couple of variations, did some Googling but without luck. Any ideas on how I can use the @PersistentCapable annotation with Scala 2.8.0 RC3? Thanks, Gero

• How to automize multiple projects build process by including digital signature of exe in Delphi?

  - by user193655

  After building a project group of 2 projects with Delphi (2009) I digitally sign the 2 exes using InstallAware Code signing, an exe that shipped with Delphi 2009. How is it possible to automize the digital signature, so when I build I can also attach digital signature. For digital signing I use a pvk (private key) file and an spc (Sw publisher certificate) file. Subquestion: Moreover I created a project group because I have 2 exes, but they are almost the same, the only thing that changes is the Application icon and the application name (one is ProductOne.dpr, the other is ProductTwo.dpr). In practice I have 2 brands of the same product, I have a single build but activation keys details activate one or the other, anyway now I was asked to change the icon and the filename, and for this I need to build 2 projects, activation key is not enough anymore to distinguish between the 2. Anyway if there is a way to do this from a single project it would be better.

• How can I prevent MEF from throwing an exception when an Export is not found?

  - by Kilhoffer

  I have a class with an IList<T> property decorated with the [ImportMany(allowRecomposition = true)] attribute. There are some conditions in which the application might not find any available Exports of the requested type. Right now, it's throwing a CompositionException if no Exports of the requested type are found. I dislike application flow being determined by thrown exceptions, so I would rather not catch and react in this case. Rather, I just want program execution to continue. Is there a flag or something I can set to make this Import optional? I know for single import properties, you can do this: [Import(AllowDefault = true)] but 'AllowDefault' is not an option on the ImportMany attribute.

• C# Spell checker Problem

  - by reggie

  I've incorporated spell check into my win forms C# project. This is my code. public void CheckSpelling() { try { // declare local variables to track error count // and information int SpellingErrors = 0; string ErrorCountMessage = string.Empty; // create an instance of a word application Microsoft.Office.Interop.Word.Application WordApp = new Microsoft.Office.Interop.Word.Application(); // hide the MS Word document during the spellcheck //WordApp.WindowState = WdWindowState.wdWindowStateMinimize; // check for zero length content in text area if (this.Text.Length > 0) { WordApp.Visible = false; // create an instance of a word document _Document WordDoc = WordApp.Documents.Add(ref emptyItem, ref emptyItem, ref emptyItem, ref oFalse); // load the content written into the word doc WordDoc.Words.First.InsertBefore(this.Text); // collect errors form new temporary document set to contain // the content of this control Microsoft.Office.Interop.Word.ProofreadingErrors docErrors = WordDoc.SpellingErrors; SpellingErrors = docErrors.Count; // execute spell check; assumes no custom dictionaries WordDoc.CheckSpelling(ref oNothing, ref oIgnoreUpperCase, ref oAlwaysSuggest, ref oNothing, ref oNothing, ref oNothing, ref oNothing, ref oNothing, ref oNothing, ref oNothing, ref oNothing, ref oNothing); // format a string to contain a report of the errors detected ErrorCountMessage = "Spell check complete; errors detected: " + SpellingErrors; // return corrected text to control's text area object first = 0; object last = WordDoc.Characters.Count - 1; this.Text = WordDoc.Range(ref first, ref last).Text; } else { // if nothing was typed into the control, abort and inform user ErrorCountMessage = "Unable to spell check an empty text box."; } WordApp.Quit(ref oFalse, ref emptyItem, ref emptyItem); System.Runtime.InteropServices.Marshal.ReleaseComObject(WordApp); // return report on errors corrected // - could either display from the control or change this to // - return a string which the caller could use as desired. // MessageBox.Show(ErrorCountMessage, "Finished Spelling Check"); } catch (Exception e) { MessageBox.Show(e.ToString()); } } The spell checker works well, the only problem is when I try to move the spell checker the main form blurs up for some reason. Also when I close the spell checker the main form is back to normal. It seems like it is opening up Microsoft word then hiding the window, only allowing the spell checker to be seen. Please help.

• C# ProgressBar design pattern

  - by MadSeb

  Hi, I'm working on a database upgrader application. The upgrader updates the schema of a database ( adds new columns, renames columns , adds new tables, new views to an existing database by executing SQL statements ). When a user wants to upgrade from version 1.0 to 2.0 , "Upgrader" objects are taken from an object factory and the "Execute" method of each "Upgrader" is called. The GUI of the application has a progress bar and each time an upgrader object performs a SQL statement the progress bar gets incremented. while (!version.Equal(CurrentVersion)) { IUpgrader myUpgrader = UpgraderFactory.GetUpgrader(version); myUpgrader.Execute(UpgradedFile,progressbar); version.Increment(); } My question is very simple : how should the upgrader object communicate with the progressbar. In the code above, the upgrader object is given direct access to the progressbar but I'm wondering if some better way of doing this or better design pattern exists. Regards, Seb

• Allow run-time configuration of web service url using ATL soap and sproxy-generated proxy class

  - by Odrade

  I have a Visual C++ application that communicates with an ASP.NET web service via ATL Soap. The client application uses an sproxy-generated proxy class for the communication. Looking at the generated proxy class, I noticed that the url for the web service is hard-coded in numerous places. It would be preferable for the url to be configurable at run-time (e.g. stored in a config file). Could anyone recommend a method for doing this? It doesn't look like the class generated by sproxy is amenable to hand-editing.

• Why isn't WH_MOUSE hook global anymore?

  - by Valentin Galea

  I have this global mouse hook setup in a DLL that watches for mouse gestures. Everything works perfectly but with a hook set for WH_MOUSE_LL which is a low-level hook and one that doesn't need to be in an external injectable DLL. Once I switch - to the more suitable one would say - WH_MOUSE mouse hook, everything falls apart. Once I click outside my main application (the one that installs the hook), the hook gets corrupted - ::UnhookWindowsHookEx will fail. I only found this guy saying at experts exchange: "No way, at least under Windows XP + SVP2 WH_MOUSE won't go global, you must use WH_MOUSE_LL instead." I setup the hooks correctly: in a DLL using a shared data section, posting and not sending messages from the hook proceduce. Why has this changed? And why is not documented? Anyone encountered this? Thanks! BTW: I've reverse engineered a bit the popular StrokeIt application and it uses a combination of WH_GETMESSAGE and WH_MOUSE hooks and still works on XP/Vista...

• file_column not creating files, just empty tmp directory

  - by Yanaek

  Up to the end of December 2009 everything worked fine, so i assume that after some upgrades on servers (Ubuntu 8.10 and second Ubuntu 9.10) something stopped working. Model: class Product < ActiveRecord::Base belongs_to :category file_column :thumbnail, :magick = { :geometry = "150x100" } there is of course table 'products' in database, and it has column 'thumbnail' what's interesting that File actually is uploaded to server, it goes to the /tmp directory under RackMultipartXXXX-0 name, and it is unmodified image. The problem is, that then this file is not moved to 'tmp' dir under RAILS_ROOT/public/product/ nor the 'XX' (where xx means ID of a product) under public/product also. i don't know what to do, i spend few HOURS trying different versions of file_column, also trying to make new, test rails application only from scaffold, but then, in this new application problem was the same

• Qt: Writing plugins for other applications

  - by Rasmus Faber

  I am writing a plugin for another application. I want to support the plugin on multiple platforms, so I am strongly considering using Qt. The plugin needs to be able to show some basic GUI. The plugin interface does not in any way handle GUI - it is just a simple DLL/shared library specified with a C-header file. Can I use Qt inside such a shared library? The calling application might or might not be using Qt itself. Any hints on what to do? Do I need to run a QApplication event-loop in a separate thread? Or can I just call the event-loop myself while waiting for input? (I only need modal dialogs).

• Memory Issues When DOM Parsing A Large XML File on Android Devices

  - by tonyc

  Hey awesome SO users, I have an Android application that parses an XML file for users and displays results in a much more mobile friendly format. The app works great for most users, but some users have lots and lots of data and the app crashes on them because it runs out of memory. Is there any way I have a DOM style XML parser quit parsing data after a certain amount of parsing? I only need the first 30 or so elements so it would make the application much more efficient. I'd like to use a SAX or pull parser instead, but the XML I'm parsing is not valid and I have no control over it. Unless anyone has some good SAX solutions that let me parse messy, invalid XML, I think DOM is the only way to go. Thanks for reading!

• FIPS-compliant encryption in .NET 2.0

  - by Odrade

  We have a .NET 2.0 application that uses the RijindaelManaged class to encrypt some sensitive data. This was fine until we ran into some machines that require the use of FIPS-compliant algorithms. We'd like to switch to AesCryptoServiceProvider, but most of our target machines haven't upgraded past .NET 2.0. Requiring an upgrade is out of the question. After all, upgrades are scary! Is there any way we could use AesCryptoServiceProvider in a .NET 2.0 application? Since 3.5 uses the 2.0 CLR, I was hoping there might be a way to build the needed libraries into the app. Failing that, could someone point me to a reference on the native API that's wrapped by AesCryptoServiceProvider?

• SHAddToRecentDocs without a file?

  - by Chris Becke

  I was toying with an IRC client, integrating it with the windows 7 app bar. To get a "Frequent" or "Recent" items list one has to call SHAddToRecentDocs API. I want to add recent IRC channels visited to the Windows 7 Jumplist for the IRC application. Now, my problem is, IRC channels don't exist in the file system. And SHAddToRecentDocs seems to insist on getting some sort of file system object. Ive tried to work around it by creating a IShellItem pointing to my application, and giving it a command line to launch the channel. The shell is rebelling however, and thus far has not visibly added any of my "recent document" attempts to the Jumplist. Is there no way to do this without creating some kind of entirely unwanted filesystem object?

• Appending Dataset in Core Data execution of Update through iTuneStore

  - by Yoon Lee

  So I have completed my code work. This is first time releasing the app through iTuneStore. Current state of reading Core Data (.sqlite) file is already prefetched (already has information like apple's 'Reciepie' program). Assuming I have successfully released through apple store, and decide to update my application to existing users. Say I have sqlite contents but it contains bit more information than previous SQLite file under same structure. Question 1. Every time update held to the existing user, does it removes previous ones and move new updated application? Question 2. if it is not, then HOW can I append the existing sql value?

• How do I share a Hibernate SessionFactory across web applications?

  - by Jer

  I have two web applications that are running on a single Tomcat server and are connected to the same database with Hibernate. I am concerned that having two SessionFactory instances running around might cause some issues. Also, since both web applications share much of the same application logic, I thought it would be a good idea to centralize as much as I could. And since I use Spring for DI and Hibernate configuration it would make sense to have a single ApplicationContext as well. How would I go about doing something like this? Do I need to deploy a headless WAR that creates an ApplicationContext and thus a SessionFactory and allow each application access to it? Is this even a good idea?
