  • Open an attachment for editing and save changes made to it

    - by Seitaridis
    My Lotus Notes document has a rich text item that stores an attachment. I want to edit the attachment and after this to save the attachment back to the Lotus Notes document. This is the script that launches the attachment: @Command([EditGotoField];"Attachment"); @Command([EditSelectAll]); @Command([AttachmentLaunch]); @Command([EditDeselectAll]) This script opens the attachment, but the changes made are not reflected to the Lotus Document. One way of solving this is to add AttachmentActionDefault=2 as an entry to the notes.ini. This enables to edit the attachment when double clicking on attachment. Also using the right click on the attachment, and then choosing edit action, produces the same result. In both cases, after saving, the changes are reflected back to the Lotus Notes document. The problem is that I want to use a button for opening the attachment.

  • Dynamically Adding Multiple User Controls vb.net

    - by Jamie Hartnoll
    I have a User Control which returns a table of data, which in some cases needs to be looped, displaying one on top of another. I am able to dynamically add a single instance of this by placing a fixed placeholder in the page. I am now trying to work out how to add more than one, given that I don't know how many might be needed I don't want to hard code the Placeholders. I've tried the following, but I am just getting one instance, presumably the first is being overwritten by the second My HTML <div id="showHere" runt="server"/> VB Dim thisPh As New PlaceHolder thisPh.Controls.Add(showTable) showHere.Controls.Add(thisPh) Dim anotherPh As New PlaceHolder anotherPh .Controls.Add(showTable) showHere.Controls.Add(anotherPh) How do I make it add repeated tables within the showHere div?

  • Never render a layout in response to xhrs

    - by Horace Loeb
    Most of the time I don't want to render a layout when the request comes from AJAX. To this end I've been writing render :layout => !request.xhr? frequently in my controller actions. How can I make this the default? I.e., I'd like to be able to write def new Post.find(params[:id]) end and have the functionality be def show Post.find(params[:id]) render :layout => !request.xhr? end (I'm fine manually specifying a layout in the rare cases in which I want to use one.)

  • Lazy evaluation in Ruby

    - by fifigyuri
    I have a situation for Ruby, where an object is possibly necessary to be created, but it is not sure. And as the creation of the object might be costly I am not too eager creating it. I think this is a clear case for lazy loading. How can I define an object which is not created only when someone sends a message to it? The object would be created in a block. Is there a way for simple lazy loading/initialisation in Ruby? Are these things supported by some gems, which provide different solutions for various cases of lazy initialisation of objects? Thanks for your suggestions!

  • Any good books out there for advanced concepts like lambdas, delegates, events etc?

    - by they_soft
    I've read about these features but I don't think I've seen enough to consistently apply them in my coding, eg "This would be better done with a delegate than with my other, outdated approach". I know what they do, but I want more examples of use cases, or want some heuristic to help me think in terms of such features. All the books I've seen either focus only on the basics or just mention the features as part of the language. Is there any book out there that deals with this? Preferably C# or language agnostic.

  • How do you share your git repository with other developers?

    - by semi
    I have a central git repository that everyone pushes to for testing and integration, but it only is pushed to when features are 'ready'. While in the middle of a big task, developers frequently have many commits that stay on their harddrives. Sometimes in the middle of these projects I'd like to either see what another developer is doing, or show him how I've done something. I'd like to be able to tell another developer to just "pull my working copy" The only way I can think of is having everyone run ssh on their development machines and adding accounts or ssh keys for everyone, but this is a huge privacy and permissions nightmare, and seems like a lot of work to maintain. Should we just be pushing to that central repository in these cases? Should we be pushing after every local commit?

  • What can explain std::cout not to display anything ?

    - by Benoît
    For whatever reason, std::cout does not display anything with my application. The description of my development environment follows. I am working on a Qt application using Qt Creator. Since Qt Creator can't be launched from my station (XP64), i am currently developping it with Visual Studio 2008 and the Qt plugin (by importing the .pro project file). Everything seems fine and the application works. In some cases (depending on command line arguments), i don't want to launch the HIM, just to display a few sentences in the CLI (command line required arguments, for instance). I don't get any error, but nothing is displayed. The corresponding code, which i am sure is run is the (classical) following : std::cout << "is this going to be displayed ?" << std::endl; Do you have any idea why nothing is displayed ?

  • Flash causing jerky javascript animations

    - by Matt Brailsford
    Hi Guys, I'm developing a site which has a flash background playing a small video loop scaled to fill the whole background. Over the top I have a number of HTML elements which are animated using javascript. The problem I am having is that (predominantly in FF, but also in others to a lesser degree) the flash seems to be causing my javascript animations to run rather jerky, and in some cases missing the animation altogether and just jumping to the end state. Does anybody have any thoughts on how to make the 2 work together nicely? Many thanks Matt

  • Centralized Credentials Service For Various Apps

    - by Vlad
    We are researching the possibility to build a centralized credentials storage for internal applications. These apps (vb6, vb.net, web apps in asp.net, etc) are using various instances of SQL servers and iSeries. We want to implement a central credentials facility that would act as a security broker. Basically it should work like this: Client app supplies AppID (I am Sales Application) and EnvironmentID (I am running in QA environment) and in return will get either a connection object (preferred) or encrypted connection string that will allow said application to connect to resources it needs. There will be cases when application needs to connect to two (or more) database resources (i.e. to SQL and iSeries). What are looking at DP API at the moment, but I am not convinced that DP API is the solution as it tied in with machine key. In our case using machine key isn't feasible, so I want to know if there are other approaches available.

  • What should I call the operation that limit a string's length?

    - by egarcia
    This is a language-agnostic question - unless you count English as a language. I've got this list of items which can have very long names. For aesthetic purposes, these names must be made shorter in some cases, adding dots (...) to indicate that the name is longer. So for example, if article.name returns this: lorem ipsum dolor sit amet I'd like to get this other output. lorem ipsum dolor ... I can program this quite easily. My question is: how should I call that shortening operation? I mean the name, not the implementation. Is there a standard English name for it?

  • Server crash = How does a TCP/IP (and the browser-client) behave after this?

    - by jens
    Hello Experts, i would be thankfull for an explanation what happens with HTTP(TCP/IP) transmissions when the server crashes unexpectedly, how does the client Browser (Firefox / IE) handle this event. What happens in the following two standard cases: Clients-actively sends data: The TCP/IP Connection has been estableshed and the Client (Web-Browser) is Sending a POST Request with some data and in the middle of the process of sending the server crashes. What does this mean for the client? As far as I know TCP/IP does not "acknowledge" a send data-package so the client does not know that the server crashed. How will the client behave? (Firefox and Internet Explorer)? The Server is actively sending data: As above the tcp/ip connection has been established and the Server is sending a large website to the client (browser). In the middle of the sending-process the server crashes, so no futher packets are sent. How does the client browser react to this event (Firefox and Interne Expolrer) Thank you very much!! Jens

  • Restlet - Access elements of the request URL

    - by DutrowLLC
    I'm unsure what the proper way is to access parts of the requested URL. In this case, I want to get the requested path without the query variables. This is the only way I found to do it: String path = getRequest().getResourceRef().getHostIdentifier() + getRequest().getResourceRef().getPath(); The result would be the bold part of this url: http://stackoverflow.com/questions/ask?query=value I also found about 6 different ways to get the server name (http://stackoverflow.com) but I'm worried that some of them would fail in certain cases that I am unaware of (why would there be 6 different ways to do one thing): getRequest().getHostRef().getHostIdentifier(); getRequest().getHostRef().getIdentifier(); getRequest().getRootRef().getHostIdentifier(); getRequest().getRootRef().getIdentifier(); getRequest().getResourceRef().getHostIdentifier(); And this seems to get the complete URL with query parameters: getRequest().getResourceRef().getIdentifier(); Any further explanation would be much appreciated.

  • Scala wont pattern match with java.lang.String and Case Class

    - by Stefan
    Hello fellow Scala Programmers I have been working with Scala for some month now, however I have a problem with some properly basic stuff, I am hoping you will help my out with it. case class PersonClass(name: String, age: Int) object CaseTester { def main(args:Array[String]) { val string = "hej" string match { case e:String => println(string) case PersonClass => println(string) } } } When I am doing like this I get error: pattern type is incompatible with expected type; found : object PersonClass required: java.lang.String case PersonClass = println(string) And if I then change the second line in the pattern matching to the following: case e:PersonClass => println(string) I then get the error: error: scrutinee is incompatible with pattern type; found : PersonClass required: java.lang.String case e:PersonClass = println(string) However if I change the string definition to the following it compiles fine in both cases. val string:AnyRef = "hej"

  • SQL joins "going up" two tables

    - by blcArmadillo
    I'm trying to create a moderately complex query with joins: SELECT `history`.`id`, `parts`.`type_id`, `serialized_parts`.`serial`, `history_actions`.`action`, `history`.`date_added` FROM `history_actions`, `history` LEFT OUTER JOIN `parts` ON `parts`.`id` = `history`.`part_id` LEFT OUTER JOIN `serialized_parts` ON `serialized_parts`.`parts_id` = `history`.`part_id` WHERE `history_actions`.`id` = `history`.`action_id` AND `history`.`unit_id` = '1' ORDER BY `history`.`id` DESC I'd like to replace `parts`.`type_id` in the SELECT statement with `part_list`.`name` where the relationship I need to enforce between the two tables is `part_list`.`id` = `parts`.`type_id`. Also I have to use joins because in some cases `history`.`part_id` may be NULL which obviously isn't a valid part id. How would I modify the query to do this?

  • Website using JEE

    - by Rob
    Hi guys, I have a simple question, but I can't find out the answer. I'm wondering if we can see that a website is built using the JEE technology, or servlets/JSP. I think it could be possible to look for specials pages from the server (404, wrong parameters, ...) in some cases, but what about the everyday use ? In fact, I look for a collection of great (or wide used) website using the java technology, and I can't really find a list of these. I'llbe very happy if you can help me with these two small questions

  • Project change makes qtp to fail

    - by Onnesh
    We are using 2 or more projects in an application to be opened. For e.g. HT1000 & HT1200 will be opened by the application, objects are the same(or common) for both the projects. Code uses the values in excel framework for running the test cases as parent to identify the child objects for e.g. Window("HT1000").Dialog("parts").Click("OK") but when we just change the parent name in excel framework as "HT1200" the objects for HT1200 are not getting accessed. How to resolve this? Is it needed to again add the HT1200 project & objects in the object repo of qtp?

  • How to correctly pop a modeless dialog from console using MFC

    - by Vertilka
    I need to create a console application that has a main() function and pop a modeless dialog, so the console can still work in parallel to the modeless dialog (do other work, like communicating with the modeless dialog). Whatever i tried, i could only pop a modal dialog. (where the console is in hold till the modal dialog close itself). When switching to modeless dialog using Create() and ShowWindow() the dialog is displayed without its controls and it freeze / block (you can see the hourglass cursor). 1) i tried to pop the modeless dialog from the main() function 2) i tried to pop the modeless dialog from the InitInstance() of a CWinApp derived class In all cases the modeless dialog freeze / block. I believe this is a one line solution. TNX,Vertilka

  • msvcrt: memory usage goes wild, but not under debugger

    - by al_miro
    I have a C++ code compiled with Intel compiler, 32bit, in MS VC6 mode, so using either msvcrt.dll or msvcrtd.dll. The process makes heavy memory allocation and deallocation. I monitor the memory usage with WMI and look at VirtualSize and WorkingSetSize. with debug runtime (msvcrtd.dll): virtual constant 1.7GB, working constant 1.2GB with non-debug runtime (msvcrt.dll): virtual raising 1.7-- 2.1GB, working raising 1.2-1.4GB with non-debug runtime but under debugger (windbg): virtual constant 1.7GB, working constant At 2.1 GB virtual the process is crashing (as expected). But why would the virtual usage increase only with (non-debug) msvcrt.dll and only if not under debugger? In all cases compilation flags are identical, only runtime libs are different.

  • Hibernate sequence should only generate when ID is <=0

    - by Tim Leys
    Hi all, I'm using the folowing sequence in my code. (I got the sequence and @Id @SequenceGenerator(name = "S912_PRO_SEQ", sequenceName = "S912_PRO_SEQ", allocationSize = 1) @GeneratedValue(strategy = GenerationType.SEQUENCE, generator = "S912_PRO_SEQ") @Column(name = "PRO_ID", unique = true, nullable = false, precision = 9, scale = 0) public int getId() { return this.id; } And using the following sequence / triggers in my DB. CREATE SEQUENCE S912_PRO_SEQ nomaxvalue minvalue 20; CREATE OR REPLACE TRIGGER S912_PRO_B_I_TRG BEFORE INSERT ON S912_project REFERENCING OLD AS OLD NEW AS NEW FOR EACH ROW ENABLE begin IF :NEW.pro_ID IS NULL THEN select S912_PRO_SEQ.nextval into :new.pro_ID from dual; END IF; end; I was wondering if there is a way to let hibernate generate a sequence ONLY if the ID is <=0 (not set) or if the ID already exists. I know for most cases my trigger would fix the situation. But I do not want to rely completely on it. I hope someone can help me out :p

  • Draw window with just borders

    - by Tonatiuh
    How can I create a application window that is showing just the borders of the window, but i don't want to show the contents of the window itself. I mean i want to see the rest of the desktop or the others windows through the entire region of my window. No using transparences. Just draw the borders. I suppose it's like detecting the messages WM_ERASEBKGND and WM_PAINT and doing nothing in these cases to force not painting in the contens, but I have tried and window is still drawing a white background. How can i get it?

  • Memory leak with preg_replace

    - by Silvio Donnini
    I'm using the preg_replace function to replace accents in a string, I'm working with UTF-8. I have incurred in what seems to be a memory leak, but I can't isolate the root cause, my code is rather simple: preg_replace( array_keys($aToNoAccents), array_values($aToNoAccents), $sText ); where $aToNoAccents is an associative array with entries like '~[A]~u' => 'A', '~[C]~u' => 'C',. My script prints this error for the above line: Fatal error: Allowed memory size of 1073741824 bytes exhausted (tried to allocate 3039 bytes) Obviously it's not a matter of increasing the allowed memory for PHP, (a 1Gb footprint is way off the scale of my application). Also, that line is executed thousands of times without problems but, just for some cases which are difficult to reproduce, it yields the error. Is anyone aware of memory problems with preg_replace and UTF-8 strings? Am I to use special care in passing actual parameters to such function? I'm using PHP 5.2.6-3 with Suhosin-Patch thanks Silvio

  • When should I observe javascript events on window vs. document vs. document.body?

    - by brahn
    I'm using prototype.js for my web app, and I have everything running on chrome, safari, and firefox. I am now working on IE8 compatibility. As I've been debugging in IE, I've noticed that there are javascript events for which I have previously set an observer on the window, e.g. Event.observe(window, eventType, function () {...}); (where eventType might be "dom:loaded", "keypress", etc.) and it works just fine in Chrome/Safari/Firefox. However, in IE the observer never fires. In at least some cases I could get this to work on IE by instead placing the observer on something other than window, e.g. document (in the case of "dom:loaded") or document.body (in the case of "keypress"). However, this is all trial-and-error. Is there some more systematic way to determine where to place these observers such that the results will be cross-browser compatible? Thanks!

  • Forms authentication for users and Windows for Database?

    - by scyonx
    On our production servers, the admins created a WebUser active directory account which is users for anonymous access to IIS and is also used to authenticate database access with our SQL Server instances using Integrated Security=SSPI in the connection string and identity impersonate="true" in the web.config. I've often come across situations where I would like to or even need to use forms authentication. However, I using forms authentication, Integrated Security seems to use the logged in user's credentials to authenticate against the database. In these cases I have changed the connection string to use the credentials of a SQL Server users instead. I would prefer to not have a hard coded username and password in the connection string or rather worse in code. Is it possible to use forms authentication just for user authentication for users and windows authentication with the IIS user for database access? What would be the best practice in such a situation?

  • Disabling Firefox spell checking in iframe-based text editors

    - by Piotr Sobczyk
    There is a lot of info around about how to disable spell checking in html textarea element by using spellcheck='false'. However to have text area with more advanced capabilities, one must use iframe with designMode = "on" (see e.g. this page, this is a way that RichTextArea is implemented in GWT) and I couldn't find a single post on that topic. It turns out that Firefox detects such advanced text areas and enables its spell checking in them. You can see it live by visiting this page from Firefox and entering some content to text field. If you inspect this code, you'll see no textarea tag, yet FF spell checking is still active. The only way I managed to disable it was setting designMode to off but... I need it to be on. The question is: Is there any possibility to disable spell checking in such cases, without setting designMode = "off"?

  • Is there a non-blocking version of MessageBox.Show (or something like it)?

    - by Dan Tao
    Often you just want to notify the user that something has occurred, but there's really no need for any input from them. In this common scenario, I sometimes see code like this: MessageBox.Show("Something has occurred", "Something", MessageBoxButtons.OK); This code, as we all know, causes a little pop-up window to appear with only an OK button. Now here's the thing: this code blocks (the UI thread). But in the vast majority of cases, it seems to me, if you only have an OK button, there's very little need to block. (Isn't the purpose of blocking typically to receive some input from the user? And if the user's only choice is "OK," in this typical case, isn't blocking pretty pointless?) Obviously I could just write my own little form that does basically exactly what MessageBox.Show does, except that it returns nothing (no DialogResult) and doesn't block. But I was just wondering if something like this exists already that I didn't know about.
