  • Why is Self assignable in Delphi?

    - by mjustin
    This code in a GUI application compiles and runs: procedure TForm1.Button1Click(Sender: TObject); begin Self := TForm1.Create(Owner); end; (tested with Delphi 6 and 2009) why is Self writeable and not read-only? in which situations could this be useful? Edit: is this also possible in Delphi Prism? (I think yes it is, see here) Update: Delphi applications/libraries which make use of Self assignment: python4delphi

  • How can two eclipse plugin use the same preferences store?

    - by St.Shadow
    I have two plugins, say com.site.plugin.core and com.site.plugin.ui. I'd like to separate core part from UI part, so at plugin com.site.plugin.ui I created Preferences page where I defined some preferences, which should be used by com.site.plugin.core. I check article at Eclipse site, but it is quite outdated, and linked bug also do not provide much info. So is it possible to do this using standard Eclipse mechanism, or I need use direct low-level API via package org.eclipse.core.runtime.preferences?

    httpd = make_server('', 80, server) webbrowser.open(url) httpd.serve_forever() This works cross platform except when I launch it on a putty ssh terminal. How can i trick the console in opening the w3m browser in a separate process so it can continue to launch the server? Or if it is not possible to skip webbrowser.open when running on a shell without x?

  • Repository - PHP

    - by Mike Silvis
    Hello, I am new to repositories and am currently looking around to find the best possible option. I need something that can handle multiple versions of our website, and allow multiple collaborators to all push to the repo together. Our current project is built in PHP, and we have a MySQL database. I am short on funding and need the best option for our money. I have limited ssh access to our server, however I have little to no experience working with repositories. Thanks, Mike

  • Locate RFID tag using iPhone

    - by Dan
    Hi all, I am looking into building an app (on my laptop to start) that would be able to locate the signal emitted by an RFID tag (non passive). Say I attach this to my key ring, what would be required of the application to triangulate the location of the RFID tag in a 10m range. Would this even be possible using this technology? I see some older posts here so wondering if there have been any tech breakthroughs in this area since then? Dan

  • EXT-GWT Portal: How to get all Portlets?

    - by Lars
    Hi all this is my first Question here! Im just making my first steps with (Ext-) GWT. I´m testing the Ext-GWT libraries and really: These are absolute great! Now my question: Is it possible to make a kind of "clear-Portal" or "hide all portles" for a defined Portal? Or have i always manually clear the portal like in my example code above? My sample code looks like this: //define the Portal, 2 columns, each 50% auf width, with borders and Backgroundcolor portal = new Portal(2); portal.setBorders(true); portal.setStyleAttribute("backgroundColor", "white"); portal.setColumnWidth(0, .50); portal.setColumnWidth(1, .50); //define a Portlet for showing all Users portletUser = new Portlet(); portletUser.setHeading("Benutzer"); configPanel(portletUser); portletUser.setLayout(new FitLayout()); CompUserList compUserList = new CompUserList(); portletUser.add(compUserList); portletUser.setHeight(250); //define a Portlet for showing all Vehicles portletVehicles = new Portlet(); portletVehicles.setHeading("Fahrzeuge"); configPanel(portletVehicles); portletVehicles.setLayout(new FitLayout()); CompVehicleList compVehicleList = new CompVehicleList(); portletVehicles.add(compVehicleList); portletVehicles.setHeight(250); //define a portlet for showing all countries portletCountries = new Portlet(); portletCountries.setHeading("Länder"); configPanel(portletCountries); portletCountries.setLayout(new FitLayout()); CompCountryList compCountryList = new CompCountryList(); portletCountries.add(compCountryList); portletCountries.setHeight(250); //add both Portlets to Portal portal.add(portletUser, 0); portal.add(portletVehicles, 1); So first of all this works fine and looks great :-) Now i have a a button in a accordeon menu. The Listener on this button should hide all portlets in the portal (at this time its the portletUser and portletVehicles) and then add another portlet (for example the portletCountries): portletUser.hide(); portletVehicles.hide(); portal.add(portletCountries, 0) Question from above again ;-) Is it possible to make a kind of "clear-Portal" or "hide all portles" for a defined Portal? Or have i always manually clear the portal like in my example code above? What is the best practice for this functionallity? Thanks all for your tips! Lars.

  • Yii PHP Framework- Implementation

    - by Josh
    I was just curious if Yii is supposed to be compiled into PHP or not. Is it possible to use Yii just by copying the Framework to a folder on the server and then including something (something as in one of the yii files- I am not sure how it works) in the scripts I wish to use the framework for? (Noob when it comes to frameworks and usage) Thanks, Josh

  • What do you think about ??= operator in C#?

    - by TN
    Do you think that C# will support something like ??= operator? Instead of this: if (list == null) list = new List<int>(); It might be possible to write: list ??= new List<int>(); Now, I could use (but it seems to me not well readable): list = list ?? new List<int>();
