  • Linux Newbie: SSH or VNC for linux admin tasks

    - by Dirk
    Longtime Windows user, looking to get my feet wet with Linux. Since Windows makes comparatively little use of the command line, I'm naturally more comfortable with GUI tools for remote server administration tasks. However, before i rush out and install a VNC server on my Linux box, I want to get a sense of how many of Linux's various packages actually offer GUI front end. If not many, then it's probably not worth the effort.

  • Multi level or progressive or incremental file search

    - by iraSenthil
    I am looking for a GUI tool in Windows, where I can do search and pass the result to next search and continue. I know I can do this in command line by piping one search result to another, but I am looking for a GUI tool. Here is a sample search, I would like to find all files that has extension ".java". From the result, find all files that has a specific word. From the result, select few files, and search only those files with another keyword.

  • Outside of a web browser, does the Javascript programming language do anything? [closed]

    - by Stom
    I often hear people talking about Javascript in conjunction with web browser programming/web page programming and such, and/or form logic, etc. However, outside of a browser, can Javascript source be written and compiled to work outside of a browser, much like C/C++ can work in a terminal window/GUI window with a library? Can I write "Hello World" in Javascript in a console terminal on a modern OS GUI and such like C?

  • Mixing Silverlight-Specific System.Xml.Linq dll with Non-Silverlight System.Xml.Linq dll

    - by programatique
    I have a Logic layer that references Silverlight's System.Xml.Linq dll and a GUI that is in WPF (hence using the non-Silverlight System.Xml.Linq dll). When I attempt to pass an XElement from GUI project to a method in the Logic project, I am getting (basically) "XElement is not of type XElement" errors. To complicate matter, I am unable to edit the Logic layer project. The Non-Silverlight DLL is at: C:\Program Files (x86)\Reference Assemblies\Microsoft\Framework\v3.5\System.Xml.Linq.dll THe Silverlight DLL is at: C:\Program Files (x86)\Microsoft SDKs\Silverlight\v3.0\Libraries\Client\System.Xml.Linq.dll I am new to C# but I'm fairly sure my issue is that I am referencing different DLL's to access the System.Xml.Linq namespace. I attempted to replace my non-Silverlight System.Xml.Linq.dll with the Silverlight's System.Xml.Linq.dll, but received assembly errors. Is there any way to resolve this short of scrapping my WPF GUI project and creating a Silverlight project?

  • Python class design - Splitting up big classes into multiple ones to group functionality

    - by Ivo Wetzel
    OK I've got 2 really big classes 1k lines each that I currently have split up into multiple ones. They then get recombined using multiple inheritance. Now I'm wondering, if there is any cleaner/better more pythonic way of doing this. Completely factoring them out would result in endless amounts of self.otherself.do_something calls, which I don't think is the way it should be done. To make things clear here's what it currently looks like: from gui_events import GUIEvents # event handlers from gui_helpers import GUIHelpers # helper methods that don't directly modify the GUI # GUI.py class GUI(gtk.Window, GUIEvents, GUIHelpers): # general stuff here stuff here One problem that is result of this is Pylint complaining giving me trillions of "init not called" / "undefined attribute" / "attribute accessed before definition" warnings.

  • Embed a Python persistance layer into a C++ application - good idea?

    - by Rickard
    say I'm about to write an application with a thin GUI layer, a really fat calculation layer (doing computationally heavy calibrations and other long-running stuff) and fairly simple persistance layer. I'm looking at building the GUI + calculation layer in C++ (using Qt for the gui parts). Now - would it be a crazy idea to build the persistance layer in Python, using sqlalchemy, and embed it into the C++ application, letting the layers interface with eachother through lightweigth data transfer objects (written in C++ but accessible from python)? (the other alternative I'm leaning towards would probably be to write the app in Python from the start, using the PyQt wrapper, and then calling into C++ for the computational tasks) Thanks, Rickard

  • Using Subversion in Xcode

    - by Kevin L.
    It seems that all of the initial Google results for "using subversion with xcode" are actually just tutorials for installing and configuring svn and Xcode, as opposed to actually using the two (i.e. interacting with svn via Xcode's GUI). Is anyone aware of a good guide that teaches the tricks and pitfalls of working with svn via Xcode's GUI? Something that bridges the gap between the most excellent Version Control with Subversion book and the Xcode IDE (as in pure Xcode GUI without any terminal command use)? Edit: We all love our terminal commands, and we all love Eclipse but (and I mean this in the nicest possible way) neither is really the point of the question. I’d prefer to use svn via Xcode’s IDE instead of via terminal just as I prefer (well, for this case) to code in Xcode’s IDE instead of using vim and gcc. Apple engineers spent a good bit of time implementing that SCM menu in Xcode; someone has to have seen a usage guide somewhere.

  • How to control a NSView, located in a dedicated NSWindow, from the main NSWindow designed to support

    - by Michael
    Hi, This is probably a simple problem for the high skilled Cocoa programmers, but I can't find how to control the graph in a separate window. I read carefully the Cocoa related books, go through many web notes,but I can't find a solution to my problem. The purpose is to use a dedicated window to draw the I=F(Vg) curves extracted by the GUI from a specific hardware. All the GUI and the hardware works fine ( thanks to the help provided by several members of stackoverflow) , but no way to send the parameters to the NSView to display the results. So far, the GUI class is based on a NSObject, the graphic class is NSView. Any idea, examples, links will be appreciated. Thank you so much. Michael

  • Python/Tkinter Audio Player

    - by Nicholas Quirk
    Hey everyone reading this, I've recently got into doing GUI development with Python. Tkinter seems like the easiest and most logical choice starting out. I did a little with wxPython but it was more sophisticated than what I needed. Anyway, I'm developing a media player. Right now it's a simple window with a button to load .wav files. The problem is I would like to implement a pause button now. But, when playing a audio file the GUI isn't accessible again (no buttons can be pushed) till the file is done playing. How can I make the GUI dynamic while an audio file is playing? I was thinking this maybe be because I'm using PyAudio, and their implementation doesn't allow this. Anyway, thanks for any advice before hand.

  • i2c on silicon image c8051f32x (using USBXpress)

    - by tosa
    I have the I2C (SMBus) working properly in this uC and have a VB GUI which can communicate over USB (using USBXpress) and do I2C transactions from the uC to a separate IC. The problem is that I am having the uC poll a register on the IC every 1s. When I do an asynchronous GUI I2C transaction, every once in a while, I believe it collides with the polling I2C transaction and all the I2C data gets shifted at the GUI (i.e., register 0x00's data shows up on register 0x01) . The I2C data in the IC looks correct (by spying on the I2C bus with a LA). What exactly is happening and how can I fix this?

  • Swapping out web services

    - by zachary
    I created a gui in .net that I want other people to use. It connects to my custom database via a web service and returns data. Now I want other people to use it. They tell me that they want to use their own database. How can I let them plug their database results into my gui? It is almost as though I want to repoint to their web service somehow.... My gui is in .net but they could be using any language even java

  • Swing Timer in Conjunction with Possible Long-running Background Task

    - by javacavaj
    I need to perform a task repeatedly that affects both GUI-related and non GUI-related objects. One caveat is that no action should performed if the previous task had not completed when the next timer event is fired. My initial thoughts are to use a SwingTimer in conjunction with a javax.swing.SwingWorker object. The general setup would look like this. class { timer = new Timer(speed, this); timer.start(); public void actionPerformed(ActionEvent e) { SwingWorker worker = new SwingWorker() { @Override public ImageIcon[] doInBackground() { // potential long running task } @Override public void done() { // update GUI on event dispatch thread when complete } } } Some potential issues I see with this approach are: 1) Multiple SwingWorkers will be active if a worker has not completed before the next ActionEvent is fired by the timer. 2) A SwingWorker is only designed to be executed once, so holding a reference to the worker and reusing (is not?) a viable option. Is there a better way to achieve this?

  • java detect clicked buttons

    - by user253530
    I have multiple panels on a JFrame window. I am going to populate each panel differently every time. For example: i start the GUI: (image center panel, right panel, bottom panel). Center panel is populated with 20 buttons, right panel with 10 buttons and bottom panel with 3. second start of the GUI (same gui). Center panel has 50 buttons, right panel has 12 buttons, bottom has 3. So everytime there is a random number of buttons, impossible to be all uniquely named. Given the fact that I don't have a unique name for each button (just a list) I would like to know which buttons were clicked according to the panel they belong to. is that possible?

  • Running Python code from Java program, shoudl i be doing this?

    - by Space Rocker
    i have a scenario where i draw a network and set all it's paraments on swing based gui, after that i have to translate this network into a python based script which another framework reads and realize this network in the form of virtual machines. As an example have look here: from mininet.topo import Topo, Node class MyTopo( Topo ): def *__init__*( self, enable_all = True ): super( MyTopo, self ).__init__() Host = 1 Switch = 2 self.add_node( Switch, Node( is_switch=True ) ) self.add_node( Host, Node( is_switch=False ) ) self.add_edge( Host, Switch ) self.enable_all() topos = { 'mytopo': ( lambda: MyTopo() ) } It simply connects a host to a switch and realize this topology on mininet framework. Now for now in order to realize the drawn network on java GUI here is what i am doing: I simply take the information from GUI and creates a new python file like the one above using java code and then run this file in mininet, which works fine somehow. I want to know, is this the correct and robust way how i am doing this or should i be looking further into java-python bridge like scenarios to be more effective or so as to say more professional.

  • Problems adding static library QT project

    - by Smek
    I have problems adding a static library to my Qt project. I have two project one is my static library and the other one is a Qt GUI project. As I add all classes to my GUI project as c++ or header files everything works just fine but I want this to be in a separate library. When I select the option to add a library I check External library then I select the .a file I have build and the folder where my header files can be found because I am working on a Mac I select Mac as the target platform. Then I click continue and then done. macx: LIBS += -L$$PWD/../../MyLib/build-MyLib-Desktop_Qt_5_2_1_clang_64bit-Debug/ -lMyLib INCLUDEPATH += $$PWD/../../MyLib/build-MyLib-Desktop_Qt_5_2_1_clang_64bit-Debug/include DEPENDPATH += $$PWD/../../MyLib/build-MyLib-Desktop_Qt_5_2_1_clang_64bit-Debug/include macx: PRE_TARGETDEPS += $$PWD/../../MyLib/build-MyLib-Desktop_Qt_5_2_1_clang_64bit-Debug/libMyLib.a When I build my GUI project I get the following error: The process "/usr/bin/make" exited with code 2.

  • iPhone / Android: what protocol stacks do apps use for connecting to centralised services?

    - by Richard
    Hi All, Aplogies for the ignorant question, I have no experience with app development on any mobile platform. Basically what I want to know is what communication protocols do apps typically use for accessing/querying centralised services? E.g if I port a webapp/service to iPhone/Andriod, typically how would I access/query this web service in my app? E.g is it over HTTP, or are there other protocols? Also, presumably the GUI of an app is constructed with Apple/Andriod GUI libraries (in java? cocoa?). Can an app GUI be defined with HTML/javascript like a webpage? Sorry again for the pure noob questions. Thanks

  • How do I change the Unit:Characters in Matlab?

    - by Jonas
    For portability, I set the units of my GUIs to 'characters'. Now I have a user who wants to use Matlab on his netbook, and the GUI window is larger than the screen (and thus cropped at the top). I think I could try and write something in the openingFcn of the GUI that measures screen size and then adjusts the GUI accordingly, but I'd rather avoid that, because I then need to deal with text that is bigger than the text boxes, etc. What I'd rather like to do is somehow adjust the unit 'character' on his Matlab installation. None of the font sizes in the preferences seem to have an effect on unit:character, though. Does anyone know whether there's a setting for that, which can be changed from within Matlab (I don't mind if it's something that is reset at every reboot, since I can just put it into the startup script)?

  • Right programing language for developing application for Mac

    - by drasto
    I'm planing to buy Mac. I would like to be able to develop GUI aplication for Mac as well. Currently I develop in C# using VisualStudio as IDE. I also know Java and I'm familiar with NetBeans IDE. Application created in both of this languages can run on Mac (as can NetBeans IDE) but I was told that neither C# nor Java is recomended for MacOS X development. So what language is recomended for MacOS X development ? I guess there is some recomodation from Apple for the developers ? I would prefer Object-oriented easy-to-use programing language (nothing like C) with good IDE that supports GUI creating (GUI designer). Thank you for answers

  • C# Multi threading- Move objects between threads

    - by Grant
    Hi, i am working with a winforms control that is both a GUI element and also does some internal processing that has not been exposed to the developer. When this component is instantiated it may take between 5 and 15 seconds to become ready so what i want to do is put it on another thread and when its done bring it back to the gui thread and place it on my form. The problem is that this will (and has) cause a cross thread exception. Normally when i work with worker threads its just with simple data objects i can push back when processing is complete and then use with controls already on the main thread but ive never needed to move an entire control in this fashion. Does anyone know if this is possible and if so how? If not how does one deal with a problem like this where there is the potential to lock the main gui?

  • Swing: Programmatically select a text

    - by HH
    Hey everyone, I have a very simple Swing GUI with just a JTetxtArea. I am trying to programmatically select a part of text using: textArea.select(startSelection,endSelection); This work. However as soon as I add some other components to the GUI I do not see selection anymore frame.getContentPane().add(button); frame.getContentPane().add(textArea); textArea.select(startSelection,endSelection); I suspect that during layouting the gui, some event causes the text to be deselected. Am I right? And could anybody suggest a solution? My goal is to have a program which displays a text, and allows the user to input start and end selection position, and a selection appears between these two position. Thank you.

  • Enable Claims based Auth on a SP2010 website, after it has been provisioned

    - by Sahil Malik
    Ad:: SharePoint 2007 Training in .NET 3.5 technologies (more information). When you provision a web app in SP2010, you can choose it to use Claims Based Auth or Classic Auth right through the GUI.  However, after you have provisioned a web app, there is no GUI to switch from Classic to Claims based. So the below powershell script will let you convert a SP2010 website to claims based auth after it has been provisioned. 1: $w = Get-SPWebApplication "http://sp2010" 2: $w.UseClaimsAuthentication = "True"; 3: $w.Update() The user running the above script should be a member of the SharePoint_Shell_Access role on the config DB, and a member of the WSS_ADMIN_WPG local group. Comment on the article ....

    - by rheide
    I could use some assistance to trying to get a Belkin N600 DB Wireless Dual-Band USB Adapter to work on a Dell Inspiron 1525 with 64-Bit Ubuntu 12.04. The device won't work out of the box. Tried to go the NDISWrapper route, but using the GUI, received the following message: Module could not be loaded. Error was: FATAL: Module ndiswrapper not found. Is the ndiswrapper module installed? Despite the fact that it showed up listed in the GUI, the device still did not function properly. How should I proceed from here?
