  • App.Config file in console application C#

    - by user1240679
    I have a console application in which I want to write the name of a file. Process.Start("blah.bat"); Normally, I would have something like that in windows application by writing the name of the file 'blah.bat' to Settings file in Properties. However, here I didn't find any Settings file and I added an app.config for the same purpose. I am not sure what to write here in app.config, that would lead to me to achieve similar thing as in windows forms. For eg: In windows forms. Process.Start(Properties.Settings.Default.BatchFile); where BatchFile is a string in settings file in Properties.

  • Basic user authentication with records in AngularFire

    - by ajkochanowicz
    Having spent literally days trying the different, various recommended ways to do this, I've landed on what I think is the most simple and promising. Also thanks to the kind gents from this SO question: Get the index ID of an item in Firebase AngularFire Curent setup Users can log in with email and social networks, so when they create a record, it saves the userId as a sort of foreign key. Good so far. But I want to create a rule so twitter2934392 cannot read facebook63203497's records. Off to the security panel Match the IDs on the backend Unfortunately, the docs are inconsistent with the method from is firebase user id unique per provider (facebook, twitter, password) which suggest appending the social network to the ID. The docs expect you to create a different rule for each of the login method's ids. Why anyone using 1 login method would want to do that is beyond me. (From: https://www.firebase.com/docs/security/rule-expressions/auth.html) So I'll try to match the concatenated auth.provider with auth.id to the record in userId for the respective registry item. According to the API, this should be as easy as In my case using $registry instead of $user of course. { "rules": { ".read": true, ".write": true, "registry": { "$registry": { ".read": "$registry == auth.id" } } } } But that won't work, because (see the first image above), AngularFire sets each record under an index value. In the image above, it's 0. Here's where things get complicated. Also, I can't test anything in the simulator, as I cannot edit {some: 'json'} To even authenticate. The input box rejects any input. My best guess is the following. { "rules": { ".write": true, "registry": { "$registry": { ".read": "data.child('userId').val() == (auth.provider + auth.id)" } } } } Which both throws authentication errors and simultaneously grants full read access to all users. I'm losing my mind. What am I supposed to do here?

  • Dereferencing deleted pointers always result in an Access Violation ??

    - by m3rLinEz
    I have a very simple C++ code here: char *s = new char[100]; strcpy(s, "HELLO"); delete [] s; int n = strlen(s); If I run this code from Visual C++ 2008 by pressing F5 (Start Debugging,) this always result in crash (Access Violation.) However, starting this executable outside the IDE, or using the IDE's Ctrl+F5 (Start without Debugging) doesn't result in any crash. What could be the difference? I also want to know if it's possible to stably reproduce the Access Violation crash caused from accessing deleted area? Is this kind of crash rare in real-life?

  • iPad pushing a split view in navigator-based application

    - by FabioWong
    I had read a lot of post from the web, but I still cannot find out how can I make this out. Please help me in detail. I need to make a split-view inside a navigation because I need to make a login system. After login, then we can see the split view. I found that someone say must need to set it to be root view, some say do not need. However I cannot do it in both way. Can anyone teach me how to do that step by step?? Here is what I did. - (void)viewDidLoad { [super viewDidLoad]; GOTSorOE_EN *gotsORoeEN = [[[GOTSorOE_EN alloc]initWithNibName:@"GOTSorOE_EN" bundle:nil]autorelease]; OEFileList_EN *oeFileListEN = [[[OEFileList_EN alloc]initWithNibName:@"OEFileList_EN" bundle:nil]autorelease]; gotsORoeEN.oeFileListEN = oeFileListEN; splitViewController = [[[UISplitViewController alloc]init]autorelease]; splitViewController.viewControllers = [NSArray arrayWithObjects:gotsORoeEN, oeFileListEN, nil]; self.view = splitViewController.view; }

  • Swing: does DefaultBoundedRangeModel coalesce multiple events?

    - by Jason S
    I have a JProgressBar displaying a BoundedRangeModel which is extremely fine grained and I was concerned that updating it too often would slow down my computer. So I wrote a quick test program (see below) which has a 10Hz timer but each timer tick makes 10,000 calls to microtick() which in turn increments the BoundedRangeModel. Yet it seems to play nicely with a JProgressBar; my CPU is not working hard to run the program. How does JProgressBar or DefaultBoundedRangeModel do this? They seem to be smart about how much work it does to update the JProgressBar, so that as a user I don't have to worry about updating the BoundedRangeModel's value. package com.example.test.gui; import java.awt.event.ActionEvent; import java.awt.event.ActionListener; import javax.swing.BoundedRangeModel; import javax.swing.DefaultBoundedRangeModel; import javax.swing.JFrame; import javax.swing.JPanel; import javax.swing.JProgressBar; import javax.swing.Timer; public class BoundedRangeModelTest1 extends JFrame { final private BoundedRangeModel brm = new DefaultBoundedRangeModel(); final private Timer timer = new Timer(100, new ActionListener() { @Override public void actionPerformed(ActionEvent arg0) { tick(); } }); public BoundedRangeModelTest1(String title) { super(title); JPanel p = new JPanel(); p.add(new JProgressBar(this.brm)); getContentPane().add(p); this.brm.setMaximum(1000000); this.brm.setMinimum(0); this.brm.setValue(0); } protected void tick() { for (int i = 0; i < 10000; ++i) { microtick(); } } private void microtick() { this.brm.setValue(this.brm.getValue()+1); } public void start() { this.timer.start(); } static public void main(String[] args) { BoundedRangeModelTest1 f = new BoundedRangeModelTest1("BoundedRangeModelTest1"); f.pack(); f.setVisible(true); f.setDefaultCloseOperation(EXIT_ON_CLOSE); f.start(); } }

  • Avoid Circular Reference in Swing GUI

    - by drhorrible
    Maybe it's not worth worrying about in this scenario, but lets say you have two classes, a JFrame with all its components, and a server-like class that handles requests from remote clients. The user is able to start and stop server objects through the GUI, and is shown various events that happen to each server object. Whether or not I use an explicit pattern (like MVC), it seems like the JFrame needs a reference to the server class (to call start and stop) and the server needs a reference to the JFrame (to notify of it of certain events). Is this a problem, or am I looking at this situation in the wrong way?

  • What is the best way to wait for a GPS location fix?

    - by qtips
    Hi, Using my Android application, when a user does a certain action, a background service is started that fetches the current GPS location and saves it in a database in addition of doing some other stuff. In that service, I use the requestLocationUpdates() from the LocationManager class and wait until the onLocationChanged() of my LocationListener (which is implemented by the service) is fired. But what is the best way to wait for the onLocationChanged to fire? Should I simply poll on a variable and wait until it is set? Any tips? Note: I cannot simply write to the database in the onLocationChanged() because of some other stuff. EDIT: To clearfy my situation, I can present an example similar to my case: Let's say user pushes a button and a method myMethod is fired which will return some object. Then, in this myMethod I will register for location updates from the GPS (using requestLocationChanged) and in addition wait for the users location and use it for something. In other words, myMethod cannot return before the location is present. I don't know how I can use onLocationChanged in this case.

  • Forking Multiple Apps Under Python Subprocess

    - by noxtion
    Hello all. I have been looking through Google and SO for something that could help me solve this but I have run into a block. I am a bit new to Python but I am looking for a way to run multiple apps that will continuously run in the background. For example, I need 4 apps to start up with a param -appnum set to a different value. I would like to use python to count up and then start up a new app that will continue to run. I assumed I would use subprocess but I feel a bit overwhelmed by the documentation. I also plan to have the app print out sequences of numbers and would like to redirect this to a file. I noticed some of the SO questions talked about this, but I am a little confused on what to do. -Mike

  • Use applescript to write iCal data to file

    - by Guy
    I am trying to get applescript to read todays ical events and write them to a file. The code is as follows: set out to "" tell application "iCal" set todaysDate to current date set time of todaysDate to 0 set tomorrowsDate to todaysDate + (1 * days) repeat with c in (every calendar) set theEvents to (every event of c whose start date = todaysDate and start date < tomorrowsDate) repeat with current_event in theEvents set out to out & summary of current_event & " " end repeat end repeat end tell set the_file to (((path to documents folder) as string) & "DesktopImage:ical.txt") try open for access the_file with write permission set eof of the_file to 0 write out to the_file close access the_file on error try close access the_file end try end try return out The ical items are getting returned correctly and the file ical.txt is created correctly in the folder Documents/DesktopImage, but the file is blank. Even if I substitute write out to the_file with write "Test string" to the_file it still comes up blank any ideas? Ty

  • Can this line of code really throw an IndexOutOfRange exception?

    - by Jonathan M
    I am getting an IndexOutOfRange exception on the following line of code: var searchLastCriteria = (SearchCriteria)Session.GetSafely(WebConstants.KeyNames.SEARCH_LAST_CRITERIA); I'll explain the above here: SearchCriteria is an Enum with only two values Session is the HttpSessionState GetSafely is an extension method that looks like this: public static object GetSafely(this HttpSessionState source, string key) { try { return source[key]; } catch (Exception exc) { log.Info(exc); return null; } } WebConstants.KeyNames.SEARCH_LAST_CRITERIA is simply a constant I've tried everything to replicate this error, but I cannot reproduce it. I am beginning to think the stack trace is wrong. I thought perhaps the exception was actually coming from the GetSafely call, but it is swallowing the exceptions, so that can't be the case, and even if it was, it should show up in the stack trace. Is there anything in the line of code above that could possible throw an IndexOutOfRange exception? I know the line will throw an NullReferenceException if GetSafely returns null, and it will also throw an InvalidCastException if it returns anything that cannot be cast to SearchCriteria, but an IndexOutOfRange exception? I'm scratching my head here. Here is the stack trace: $LOG--> 2010-06-11 07:01:33,814 [ERROR] SERVERA (14) Web.Global - Index was outside the bounds of the array. System.Web.HttpUnhandledException: Exception of type 'System.Web.HttpUnhandledException' was thrown. ---> System.IndexOutOfRangeException: Index was outside the bounds of the array. at IterateSearchResult(Boolean next) in C:\Projects\Web\UserControls\AccountHeader.ascx.cs:line 242 at nextAccountLink_Click(Object sender, EventArgs e) in C:\Projects\Web\UserControls\AccountHeader.ascx.cs:line 232

  • Python Threading, loading one thread after another

    - by Michael
    Hi, I'm working on a media player and am able to load in a single .wav and play it. As seen in the code below. foo = wx.FileDialog(self, message="Open a .wav file...", defaultDir=os.getcwd(), defaultFile="", style=wx.FD_MULTIPLE) foo.ShowModal() queue = foo.GetPaths() self.playing_thread = threading.Thread(target=self.playFile, args=(queue[0], 'msg')) self.playing_thread.start() But the problem is, when I try to make the above code into a loop for multiple .wav files. Such that while playing_thread.isActive == True, create and .start() the thread. Then if .isActive == False, pop queue[0] and load the next .wav file. Problem is, my UI will lock up and I'll have to terminate the program. Any ideas would be appreciated.

  • Capistrano update causes C: to be placed in the current directory (cygwin)

    - by user321775
    When I run cap deploy:update in a directory on my local machine (via cygwin), "C:" magically appears in the directory. Sure enough, I can cd to it and it's my windows C: drive. Now I'm afraid to delete it, but I definitely don't want it in this directory (a rails project under /home/username/blah/blah). Here's my config/deploy.rb file. custom options set :application, "xyz.com" set :repository, "ssh://[email protected]:yyyy/home/git/xxx" set :user, "myname" set :runner, user set :use_sudo, false server "xxx.xxx.xxx.xxx:yyyy", :app, :web, :db, :primary = true deploy to set :deploy_to, "/home/myname/public_html/xyz" repository set :scm, :git set :deploy_via, :copy ssh options default_run_options[:pty] = true ssh_options[:paranoid] = false ssh_options[:port] = yyyy start passenger namespace :deploy do task :start do ; end task :stop do ; end task :restart, :roles = :app, :except = { :no_release = true } do run "#{try_sudo} touch #{File.join(current_path,'tmp','restart.txt')}" end end Anyone see the problem? And does anyone know a safe way of getting rid of the C: drives that have already shown up (this has happened in a few directories)?

  • How can I send keypresses to a running process object?

    - by Waffles
    I am trying to make C# launch an application (in this case open office), and start sending that application keypresses such that it would appear as though someone is typing. So ideally, I would be able to send a running open office process the keypress for the letter "d", and open office would then type d on the paper. Can anyone give me direction as per how to go about this? I have tried to do the following: p = new Process(); p.StartInfo.UseShellExecute = true; p.StartInfo.CreateNoWindow = false; p.StartInfo.FileName = processNames.executableName; p.Start(); p.StandardInput.Write("hello"); But that doesn't get me the desired effect - I don't see the text typed out in open office.

  • changing the last commit message without committing newest changes

    - by Oleg2718281828
    My ideal workflow would consist of the following steps edit the code compile git commit -a -m "commit message" start running the new binaries, tests, etc. (may take 10+ minutes) start new changes, while the binaries are still running when step # 4 is finished, edit the commit message from step # 3, without committing the changes introduced in step # 5, by adding, say, "test FOO failed" I cannot use git commit -a --amend -m "new commit message", because this commits the new changes as well. I'm not sure that I want to bother with staging or branching. I wish I could just edit the commit message without committing any new changes. Is it possible?

  • How to force VS to react on a changing of an attached property in design time?

    - by sedovav
    Imagine, we have a wpf class library with a window1.xaml and a resource dictionary res.xaml defined in it. I know how to use styles that defined in the res.xaml for the controls that defined into the window: <Window x:Class="...Window1"> <Window.Resources> <ResourceDictionary> <ResourceDictionary.MergedDictionaries> <ResourceDictionary Source="res.xaml"/> </ResourceDictionary.MergedDictionaries> </ResourceDictionary> <\Window.Resources> </Window> So we can use the dictionary's styles for all elements into the window (except the window element... I don't know how to set the style from the res.xaml for the window :( ). I saw the article where describes how to create and use attached property to add resource dictionaries to a FrameworkElement.Resources.MergedDictionaries list. It's good! We can do the same as we done in the example above but we can use the window style now. It looks like this: <Window x:Class="...Window1" xmlns: resources="..." resources:SharedResources.MergedDictionaries="res.xaml"> </Window> That's good but VS2008 cannot recognize resources from res.xaml in design time. So we have a sad situation: all styles from res.xaml are available in run-time but in the design-time VS cannot display the window (it can't find the mentioned styles). Does anybody know how to fix this situation?

  • [jQuery UI - Accordion] Styling active header?

    - by RC
    Hi, Simple issue: I am using Accordion without any UI themes (just barebones, using my own CSS). So far, so good, except that I cannot figure out how to set an "active" style for the currently selected header. The jQuery code: $("#menu").accordion({ event:"mouseover",header:"a.top" }); The HTML code: <a href="#" class="top">XXX1</a> <div class="sub"> <a href="#">Subheading 1</a> <a href="#">Subheading 2</a> <a href="#">Subheading 3</a> </div> <a href="#" class="top">XXX2</a> <div class="sub"> <a href="#">Subheading 1</a> <a href="#">Subheading 2</a> <a href="#">Subheading 3</a> </div> This works great, except that I cannot find a way to define the styles for the active header without using ThemeRoller. Manually setting the following styles in my CSS has no effect: .ui-state-active .ui-widget-content .ui-state-active .ui-state-active a .ui-state-active a:link .ui-state-active a:visited Assistance, please?

  • Including Data From DropDownList Into Gridview

    - by Mike Keller
    I feel a little embarassed posting two questions relating to the same problem, but the first one ended up answering a question that I believe is unrelated to the solution so I'm leaving it up and outlining what I'm trying to accomplish with the hopes that someone can help out a .Net noob. What I need to be able to do is create a field in my gridview that contains a link that passes two variables. One is pulled from within the gridviews datasource and the other needs to be pulled from a textbox control outside the gridview. From what I've read so far you cannot use a hyperlinkfield for this as the datanavigateurlfields cannot be set to pull from anything but the gridview's data source. What I attempted to do was create a template field where in the itemtemplate I called: <a href="example.aspx?e=<%# Eval(ExampleList.SelectedItem.Value) %>">Test</a> That comes back with an error like this: DataBinding: 'System.Data.DataRowView' does not contain a property with the value 'TestData' Any clues to make this happen would be appreciated, like I said I'm pretty new to .Net so please be gentle. I tried to do my homework before posting this.
