  • C# Same DataSource + Multiple DataGridViews = Data Binding Issues?

    - by C. Griffin
    Here's what I'm doing: I have (2) DataGridView controls DGV #1 is bound to the DataSet, DGV #2 is bound to a DataView of the SAME DataSet Now, what I'm needing to accomplish here is this: When a user checks a boolean column on the original DGV, the second DGV should now display the newly checked row also. The context is that the first DGV is a master list, and the second one is a "favorite" view of the first. When I check the rows, the favorite column does NOT update. Do I need to use a DataAdapter to actually update the database, or can I operate directly on the DataSet (DataTable) -- or even with the Rows in the original DataGridView?

  • Silverlight Spring Effect on TextBlock control

    - by CJCraft.com
    Hi, I'd like to create view that if the user clicks on a control, let's say a TextBlock, that the control would spring back and forth in place from where the user clicked. By spring I mean push back and forth like if there were springs behind the TextBlock in each corner. I've seen demos of this type of effect, and for the life of me, I can't come up with the name of the effect to help with searches, or find an example of this. Maybe instead of a TextBlock it would help to image a picture that could be pressed down on, and as if springs were behind it and then would bounce back into place.

  • Low-overhead way to access the memory space of a traced process?

    - by vovick
    Hello all. I'm looking for an efficient way to access(for both read and write operations) the memory space of my ptraced child process. The size of blocks being accessed may vary from several bytes up to several megabytes in size, so using the ptrace call with PTRACE_PEEKDATA and PTRACE_POKEDATA which read only one word at a time and switch context every time they're called seems like a pointless waste of resources. The only one alternative solution I could find, though, was the /proc/<pid>/mem file, but it has long since been made read only. Is there any other (relatively simple) way to do that job? The ideal solution would be to somehow share the address space of my child process with its parent and then use the simple memcpy call to copy data I need in both directions, but I have no clues how to do it and where to begin. Any ideas?

  • How to add up amount of data from an external file in C# (Stream Reader)

    - by user2985995
    I'm new to this site, and pretty new to programming, at the moment I'm trying to display a count amount for the users names on my donation list, and then I also want to have a sum to work out the total amount of money the donation list contains, If someone could help me with creating a way to add up amount of donors on the donations.txt file that would be great help, I have no idea where to start, but so far this is my coding: string sName; double dAmount; string sTotalNames; double dAmountTotal; double dAmountAverage; using (StreamReader sr = new StreamReader("Donations.txt")) { while (sr.Peek() != -1) { sName = sr.ReadLine(); Console.WriteLine(sName); dAmount = Convert.ToDouble(sr.ReadLine()); Console.WriteLine(dAmount); } Console.WriteLine("Press any key to close"); Console.ReadKey(); }

  • Mercurial and particular files branching

    - by zerkms
    The context: i have a project, that contains configs/ directory, which contains (surprise-surprise!) a set of config files: database.php, facebook.php, twitter.php, cache.php, etc What I did in svn: I have created branches per specific file and made changes there (changed database connections, facebook API keys, etc). So they were stored in my private branch. Now I'm trying to migrate to "modern" nowadays DSCM - Mercurial. And I cannot get any possibility of doing the same. Any ideas?

  • How to get data from dynamically created EditText views and insert it into an array?

    - by Snwspeckle
    So basically what I need my program to do at this point is that when I click the submit button, I need to loop through each dynamic row of the ListView and grab the value in the EditText view and then insert that into an array which I will do further calculations after. Here is my code right now. package com.hello_world; import java.util.ArrayList; import com.hello_world.ByteInputActivity.MyAdapter.ViewHolder; import android.app.Activity; import android.content.Context; import android.os.Bundle; import android.util.Log; import android.view.KeyEvent; import android.view.LayoutInflater; import android.view.View; import android.view.View.OnFocusChangeListener; import android.view.View.OnKeyListener; import android.view.ViewGroup; import android.widget.BaseAdapter; import android.widget.Button; import android.widget.EditText; import android.widget.ListView; import android.widget.TextView; public class ByteInputActivity extends Activity { private ListView myList; private MyAdapter myAdapter; private Integer resQuestions; private Integer indexVal = 0; private View caption; ViewHolder holder; ArrayList<Integer> intArrayList = new ArrayList<Integer>(); @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.fieldlist); //Gets number of questions from MainActivity Bundle extras = getIntent().getExtras(); if(extras !=null) { resQuestions = extras.getInt("index"); } myList = (ListView) findViewById(R.id.FieldList); myList.setItemsCanFocus(true); myAdapter = new MyAdapter(); myList.setAdapter(myAdapter); Button submit = (Button) findViewById(R.id.btn_New); submit.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { for (int i = 0; i < myList.getCount() ; i++) { View vListSortOrder; vListSortOrder = myList.getChildAt(i); String temp = holder.caption.getText().toString(); Log.e("VALUES", "" +temp); } } }); } public class MyAdapter extends BaseAdapter { private LayoutInflater mInflater; public ArrayList myItems = new ArrayList(); public MyAdapter() { mInflater = (LayoutInflater) getSystemService(Context.LAYOUT_INFLATER_SERVICE); for (int i = 0; i < resQuestions; i++) { ListItem listItem = new ListItem(); listItem.caption = "Index " + i; listItem.indexText = "Index " + i; myItems.add(listItem); indexVal += 1; } notifyDataSetChanged(); } public int getCount() { return myItems.size(); } public Object getItem(int position) { return position; } public long getItemId(int position) { return position; } public View getView(int position, View convertView, ViewGroup parent) { if (convertView == null) { holder = new ViewHolder(); convertView = mInflater.inflate(R.layout.item, null); holder.indexText = (TextView) convertView .findViewById(R.id.textView1); holder.caption = (EditText) convertView .findViewById(R.id.ItemCaption); convertView.setTag(holder); } else { holder = (ViewHolder) convertView.getTag(); } //Fill EditText with the value you have in data source holder.caption.setText(""); holder.caption.setId(position); holder.indexText.setText("Index " + position); holder.indexText.setId(position); //we need to update adapter once we finish with editing holder.caption.setOnFocusChangeListener(new OnFocusChangeListener() { public void onFocusChange(View v, boolean hasFocus) { if (!hasFocus){ final int position = v.getId(); final EditText Caption = (EditText) v; myItems.set(position, Caption.getText().toString()); } } }); return convertView; } class ViewHolder { EditText caption; TextView indexText; } class ListItem { String caption; String indexText; } } }

  • jQuery Animation and Classes

    - by ehdv
    Assume you have a list item, <li id="foo"> which you want to fade from one color to another when moused over, and that you are using jQuery. This is fairly easy: $('li#foo').bind('mouseenter' , function(e) { $(this).animate({backgroundColor: '#F00'} , 300); }); However, what if you wanted to get the resulting color or other style rules from a class defined in CSS without also declaring them in JavaScript? It seems there's no way to learn style information from CSS rules without having an example of the rule already in the document, which would require you to animate the <li> to the target appearance, then in the animation-finished callback, set the class which leads to redundant style declarations and can foul up your CSS at "runtime". Sorry if this question's unclear: It doesn't occur in the context of any specific project, I'm just curious how you'd go about this. Also, I know CSS3 hypothetically includes support for such transitions but using CSS for dynamic behavior like this seems such an ugly hack.

  • Capture variable assignments in a Perl eval

    - by Bruce
    I would like to be able to capture variable assignments from a Perl eval. That is, to determine what variable names have been assigned to within the code and extract their value. For example if I run: eval '$foo=42; $bar=3.14;' The result of the eval is 3.14 (the last value evaluated), but I would also like to be able to determine the names "$foo" and "$bar" and their values (without knowing the names in advance). I have read up on a couple of ways of inserting variables into the eval block, through Safe and Eval::Context, but not yet any way of extracting them. I am more familiar with Python's eval/exec which have built in support for this.

  • Rails - set POST request limit (file upload)

    - by Fabiano PS
    I am building a file uploader for Rails, using CarrierWave. I am pretty happy about it's API, except that I don't seem to be able to cut file uploads that exceed a limit on the fly. I found this plugin for validation, but the problem is that it happens after the upload is completed. It is completely unacceptable in my case, as any user could take the site down by uploading a huge file. So, I figure that the way would be to use some Rack configuration or middleware that will limit POST body size as it receives. I am hosting on Heroku, as context. *I am aware of https://github.com/dwilkie/carrierwave_direct but it doesn't solve my issue as I have to resize first and discard the original large image.

  • NoMethodError in UsersController#create

    - by Mike DeVerna
    I'm getting stuck on an error I'm getting when signing up a new user in Michael Hart's Ruby on Rails Tutorial. I'm new to rails but I've been searching for hours and can't seem to find anything to figure out the issue. My initial thought is that it's specific to the following line: redirect_to @user This is my file for users_controller.rb #!/bin/env ruby # encoding: utf-8 class UsersController < ApplicationController def show @user = User.find(params[:id]) end def new @user = User.new end def create @user = User.new(params[:user]) if @user.save flash[:success] = "Welcome to the Sample App!" ?????????????? redirect_to @user else render 'new' end end end This is the error message I get: NoMethodError in UsersController#create undefined method `??????????????' for # Rails.root: /Users/mikedeverna/Documents/rails_projects/sample_app Application Trace | Framework Trace | Full Trace app/controllers/users_controller.rb:18:in `create' Here is the code in my routes.rb file: SampleApp::Application.routes.draw do resources :users resources :sessions, only: [:new, :create, :destroy] root to: 'static_pages#home' match '/signup', to: 'users#new' match '/signin', to: 'sessions#new' match '/signout', to: 'sessions#destroy', via: :delete match '/help', to: 'static_pages#help' match '/about', to: 'static_pages#about' match '/contact', to: 'static_pages#contact'

  • javascript / jQuery variable problem (possibly caching issue)

    - by waitinforatrain
    Standard AJAX query with jQuery: var globalTitle = ""; var pages = ["a", "b", "c"]; for (var i = 0; i < pages.length; i++) { createpage(pages[i]); } function createpage(title) { globalTitle=title; console.log (globalTitle); //All looks good here $.ajax({ url: "createpage.php?id=" + title, context: document.body, success: success }); } The success() function uses globaltitle which is why I had to declare it global. In the success() function though console.log (globalTitle); constantly gives me "a". It's like the variable is assigned but is then cached every time success() is called. Happens in FF 4 and Chrome 8. Any thoughts?

  • Double right click to Show a PopUpMenu with A TListView !!

    - by djiga4me
    Hi, I have a TListView and TPopupMenu, and I want to show a context menu when I right click on a TListItem. I tried the "AutoPopup" by assigning the component, but on a right click the PopupMenu is shown only and the wanted element is not selected. So i tried to use the "OnMouseDown", but we need to click and click again to show the menu on the wanted item. The first click is to select the item and the second shows the menu. But I want just a one click to do the two things. Do you have and idea about the problem? Thank you.

  • Continue Drupal processing after page send.

    - by David
    I need to do some additional processing after a Drupal page has been sent. I know I could fire a background shell command, but I need the current Drupal execution context to be maintained. I've spent a lot of time looking, but I can't find any documentation in this regard. This is surprising because it must surely be a common requirement. The only real idea I have is to fire up Drupal (again) via a shell command (exec, etc) and supply it with a pseudo path which would invoke the continued processing. But this seems unnecessarily complex/wasteful. Any pointers greatly appreciated, tks.

  • Preventing the "[YourProgramName] has stopped working" dialog on unhandled exceptions.

    - by Serapth
    I have a WinForm application, with some dependencies on an external library that can on occasion cause an exception outside of the running threads context. As it stands now, this is completely OK behavior ( well, except of course the exception ) and we wired up AppDomain.CurrentDomain.UnhandledException to simply restart the program. The only problem is, the [Your Program] has stopped working like the one below, appears: Is there a way to prevent this dialog from appearing at all, be it in the AppDomain unhandled exception handler or in a config setting, as no end users are going to be reading it and it just holds up resources until it is clicked.

  • monitoring streaming server and display throughput

    - by I__
    Scenario: laptop (running RHEL 5.3 / 5.4) with Wi-Fi allowing incoming connections (the laptop is the DHCP server and default gateway of any device that connects to it). The laptop has a streaming server installed (my app). I need to program an app that could monitor this link (device / streaming server) and display the throughput. More importantly, I need this app to be able to throttle the throughput. Think WANem but as an app, or netlimiter but (way) simpler and for RHEL. If you need clarifications, let me know. is there a library that could help me? i've done mostly windows business applications programming, and i have no clue about this stuff. please help me to get started!
