  • Freezing the header of composite report in PowerBuilder 6.5

    - by DVK
    Setup: Using PowerBuilder 6.5. I have a composite report (with a report header) which is created from two unrelated individual DataWindows. Question: In composite presentation style, how can I freeze (lock) composite report header along with the column headers in the top DataWindow? E.g. When you scroll down the composite report, both of the headers should remain visible. Thanks!

  • How to do HTTP authentication with Goliath/Heroku?

    - by David
    I'm using Goliath as my app server, and I am trying to convert "Ruby – Secure staging environment of your public app from users and bots" so it applies to my Goliath application. I am trying to use Rack::Static but I'm not sure how to write the code. I was trying something like: class Application < Goliath::API use(Rack::Lock) But I am not really sure how to translate the link I posted. I'm open to other alternatives, I just need my whole site password protected.

  • maven conditional dependencies

    - by Joshua
    We would like to bundle library dependencies from (Alfresco or Jackrabbit or ...) based on the customer choice. The number of dependencies actually varies based on the chosen vendor. How do we provide hooks at the maven level, so that the final product just includes the dependent jars as per customer selection.

  • Where should jpos.xml be located for JPos Tomcat app.?

    - by user258526
    I am trying to add in a new driver to our system running under Tomcat. The vendor has provided a JPos driver, my question is where to put the jpos.xml file so Tomcat can find it? I tried putting it in tomcat\common\classes but still get a JPOSException "Service does not exist in loaded JCL registry" when I try to open it. Help!

  • Using in app purchase to unlock features vs. using free & paid app versions for iPhone

    - by yabada
    I have an app that I was going to release as a free (lite) version with some of the total functionality and a paid full version with advanced functionality. Now, with in app purchase for free apps I am thinking of going that route with the ability to unlock features as needed. I'm not talking about a trial version that expires.I want people to be able to try out the app and get an idea of the interface and functionality before deciding to purchase the full functionality of each major section of the app, basically. Here's an analogy of what my app would be like. Let's say you have a cooking app that teaches you to cook in different styles. There could be major section for French, Italian, and Chinese. Each section could have some rudiments unlocked in the free app so users can see the UI and basics of the functionality. Then, the user could decide to purchase each major section (or not) individually with in app purchase or buy the full versioned app (with the free/paid model). One concern I have with offering a free app with in app purchase would be with feedback. I would be very clear in my description in the app store that there is in app purchase for full features but I'm worried that less serious users could/would leave negative feedback. I suppose that's always a risk but curious about any experience with this. It also seems that it could be a whole lot more complicated keeping track of what portions of the app are locked and unlocked with in app purchase. I know I'd have to have all the code for the full functionality and "lock" the portions that haven't been purchased. How do people usually lock portions of their code? I'm not talking about the process of purchasing (I've read the In App Purchase Programming Guide) but after the purchase has been made. Would I just keep track of what the user has purchased and put conditionals on the sections that are initially locked? Or is there another way to do this as well? My instinct is for the in app purchase (particularly since users could purchase the major sections that they want individually).

  • problem with two .NET threads and hardware access

    - by mack369
    I'm creating an application which communicates with the device via FT2232H USB/RS232 converter. For communication I'm using FTD2XX_NET.dll library from FTDI website. I'm using two threads: first thread continuously reads data from the device the second thread is the main thread of the Windows Form Application I've got a problem when I'm trying to write any data to the device while the receiver's thread is running. The main thread simply hangs up on ftdiDevice.Write function. I tried to synchronize both threads so that only one thread can use Read/Write function at the same time, but it didn't help. Below code responsible for the communication. Note that following functions are methods of FtdiPort class. Receiver's thread private void receiverLoop() { if (this.DataReceivedHandler == null) { throw new BackendException("dataReceived delegate is not set"); } FTDI.FT_STATUS ftStatus = FTDI.FT_STATUS.FT_OK; byte[] readBytes = new byte[this.ReadBufferSize]; while (true) { lock (FtdiPort.threadLocker) { UInt32 numBytesRead = 0; ftStatus = ftdiDevice.Read(readBytes, this.ReadBufferSize, ref numBytesRead); if (ftStatus == FTDI.FT_STATUS.FT_OK) { this.DataReceivedHandler(readBytes, numBytesRead); } else { Trace.WriteLine(String.Format("Couldn't read data from ftdi: status {0}", ftStatus)); Thread.Sleep(10); } } Thread.Sleep(this.RXThreadDelay); } } Write function called from main thread public void Write(byte[] data, int length) { if (this.IsOpened) { uint i = 0; lock (FtdiPort.threadLocker) { this.ftdiDevice.Write(data, length, ref i); } Thread.Sleep(1); if (i != (int)length) { throw new BackendException("Couldnt send all data"); } } else { throw new BackendException("Port is closed"); } } Object used to synchronize two threads static Object threadLocker = new Object(); Method that starts the receiver's thread private void startReceiver() { if (this.DataReceivedHandler == null) { return; } if (this.IsOpened == false) { throw new BackendException("Trying to start listening for raw data while disconnected"); } this.receiverThread = new Thread(this.receiverLoop); //this.receiverThread.Name = "protocolListener"; this.receiverThread.IsBackground = true; this.receiverThread.Start(); } The ftdiDevice.Write function doesn't hang up if I comment following line: ftStatus = ftdiDevice.Read(readBytes, this.ReadBufferSize, ref numBytesRead);

  • Did iPhone Simulator 3.0 break two-finger div scrolling?

    - by Edward
    I recently upgraded to iPhone Simulator 3.0, and when I do a two-finger scroll on a div (in Safari or UIWebView), it no longer works. To do a two-finger scroll in iPhone simulator, hold option to get two fingers, hold shift to lock the fingers in place relative to eachother, and then click and drag the div. You can try scrolling the example div on this page: http://www.domedia.org/oveklykken/css-div-scroll.php Can anyone reproduce this?

  • I need to modify the code of a third-party gem, where and how to do?

    - by Freewind
    I'm building a website based on RoR, and using a third-party gem "devise". I have used rake gems:unpack to unpack the "devise" to my "vendor/gems" directory. Now, I found the method "SessionsController.create" provided by "devise" is not fit my requirement, and I want to modify it. But I don't know what it is best way: just modify the method SessionsController.create" directly? create another SessionsController and override the "create" method?

  • active_scaffold routing error

    - by Elizabeth Buckwalter
    If you haven't seen my question yesterday, this is my second rails app. The first went nice and smooth, but this one keeps giving me one random error after another. I installed active_scaffold for this app as well as the last app (the first error, instead of using script/install plugin git://active_scaffold repository, I did script/install plugin http://active_scaffold repository.) I didn't want to spell out basic CRUD on minor models. After the install problems, (before I found the http solution from a windows user when I'm on Linux) I thought I'd try out Hobo. Well, Hobo updated actionmailer, actionpack, activerecord, activeresource, and installed rack. Rails isn't even using the updated versions. But as you can see at the bottom of the trace it's using rack. I have a feeling it has something to do with my futzing around with installing Hobo which I uninstalled. Thanks in advanced. [Edit] I had asked the question over at the ActiveScaffold Group the answer (if you don't want to follow the link) was that this line needed to be added to routes: map.resources :modelName, :active_scaffold => true It doesn't entirely answer my question, since the documentation said nothing about changing routes. But, it works. [/Edit] ActionController::RoutingError in Departments#index Showing vendor/plugins/active_scaffold/frontends/default/views/_list_header.html.erb where line #8 raised: No route matches {:_method=:get, :action="show_search", :controller="departments"} Extracted source (around line #8): 5: <% next if controller.respond_to? link.security_method and !controller.send(link.security_method) -%> 6: <% next if link.action == 'new' && params[:nested].nil? && active_scaffold_config.list.always_show_create %> 7: <% next if link.action == 'show_search' && active_scaffold_config.list.always_show_search %> 8: <%= render_action_link(link, new_params) -%> 9: <% end -%> 10: 11: <%= loading_indicator_tag(:action => :table) %> Trace of template inclusion: vendor/plugins/active_scaffold/frontends/default/views/list.html.erb Full Trace It was taking forever to format it.

  • How do I get Emacs to evaluate a file when a frame is raised?

    - by Brad Wright
    Basically I have my Emacs set up so it has a GUI specific elisp, but when starting it in daemon mode this doesn't evaluate. The code is something like: ;; gui.el (when window-system (progn ;; do stuff here )) I'd like this file (or at least the code within it—perhaps a funtion) to be re-evaluated when I run emacsclient -c on the command line, as I miss out on all my font-lock and color-theme goodness (as I have that stuff set to runonly when a GUI exists).

  • Usage of open source libraries in high governance and risk-averse large organizations (banks, financ

    - by bart
    Does anyone have any good stories of these kinds of organizations being open to using open source dependencies (and also tools). Many staff I've encountered have little or no exposure to open source/systems and open source is treated with great suspicion. Some reasons given for this are lack of support and robustness, which is ironic given the number of end-of-life unsupported vendor products that are in production. I'm also interested in any success stories where you've seen open source go into orgs like this and have a real benefit!

  • Trigger Code on a table in my ERP Database

    - by David Stein
    My ERP Vendor has the following trigger on a table: SET ANSI_NULLS ON GO SET QUOTED_IDENTIFIER ON GO CREATE TRIGGER [dbo].[SOItem_DeleteCheck] ON [dbo].[soitem] FOR DELETE AS BEGIN DECLARE @RecCnt int, @LogInfo varchar(256) SET @RecCnt = (SELECT COUNT(*) FROM deleted) IF @RecCnt > 150 BEGIN RAISERROR (54010, 18, 1, 'SOItem') WITH LOG ROLLBACK TRANSACTION END SET @LogInfo = 'Deleting ' + LTRIM(STR(@RecCnt)) + ' Rows From SOItem' EXEC LogDeletes @LogInfo END GO This seems very inefficient to me. Doesn't select count(*) take longer than Count(specific field)?

  • Problem getting ar_mailer/ar_sendmail working on new server

    - by Max Williams
    Hey all. I've got a new app up and running on a new ubuntu server. It's working fine generally but i can't get ar_sendmail working. I'm following the instructions on this page: http://www.ameravant.com/posts/sending-tons-of-emails-in-ruby-on-rails-with-ar_mailer The setup is all done, ie i can "deliver mails" which just saves records in my Email table. Now i want to get the ar_sendmail daemon running to actually send them. (so i'm at 'Running ar_sendmail in daemon mode' in that web page). First thing: ar_sendmail --mailq >>ar_sendmail: command not found Ok...so, where is ar_sendmail? I have a look and there's an ar_sendmail file in the bin folder of the ar_mailer plugin, so i add the location of that to my path. I don't know if this was the right thing to do or not. Ok, so try again. ar_sendmail --mailq /var/www/apps/millionaire/vendor/plugins/ar_mailer/bin/ar_sendmail:3:in `require': no such file to load -- action_mailer/ar_sendmail (LoadError) from /var/www/apps/millionaire/vendor/plugins/ar_mailer/bin/ar_sendmail:3 hmm. Here's the offending file, there's not much there. #!/usr/bin/env ruby require 'action_mailer/ar_sendmail' ActionMailer::ARSendmail.run ok...so it literally is just trying to require this and can't find it. The file, action_mailer/ar_sendmail.rb is in the ar_mailer plugin, in it's lib folder. So, given that it's being called from inside the plugin, it should be able to see this right? I've got a feeling that i'm way off the track here and have missed something simple. Can anyone set me straight? I'm using rails 2.3.4 in case that's relevant. EDIT - i just realised something kind of dumb: when i call ar_sendmail from the command line like this, i'm just loading that one file, which doesn't know where it's supposed to look for the rest of the stuff, i think. Which really makes me think that i'm not trying to run the right thing. Is the ar_sendmail daemon a seperate program altogether, that i would get with apt_get or something? EDIT2 - i made some progress by installing the ar_mailer gem (which the guide said i shouldn't do) and that does seem to run. It's sending some mail request somewhere and clearing the Email table of pending emails. Running ar_sendmail in -ov (oneshot verbal) mode i see it report this for example: sent email 00000000019 from [email protected] to [email protected]: # So, it actually looks like it's working now and i just need to set up the ACTUAL THING WHICH SENDS EMAILS. sigh. still grateful for any advice. thanks, max

Is there any way to make multiline TextBox to lock inserted lines or inserted text and allow to only add text? Thanks in advance.

  • Reloading of persisted entity

    - by Udi
    I'm using OpenJPA in my application as a JPA vendor. The question is theoretical or conceptual: Is there any way to tell an entity manager to load an entity from the DB rather than from it's cache? The problematic scenario: EM1.persist(Entity1) EM2.merge(Entity1) EM1.find(Entity1) <--- Entity1 is the cached version rather than the merged one.. Any elegant way to do it? I really don't want to call em.refresh(entity).
