C# :: Managing Multiple Button Events Using Array
Apr 19, 2014I'am creating a 10x10 graph of nodes. Each node is a button object.
Instead of coding the click event procedure for each (As each button will do the same thing when clicked), how would I implement a single click event method for all of the buttons within a Button array.
Picture of the 10x10 grid
EDIT: Each button would return its location (x,y) to the node class.
I'm attempting to write a basic Dijkstra's algorithm using a 10x10 grid.

C# :: Multiple Pages On WPF Button Click
Oct 24, 2014For now the app creates a new DateTime property which is binded to a label and shows the user the current time. Eventually I want to have the ability to select the timezone you are in, change font/background colors/etc etc... But that is all in time. My current step that I am trying to implement is having a button click (Binded to an event method) change screens. I find it hard to explain in words, but I would like the same Window to be used, just have different functions on the other when the button is clicked. So for example...
The only way I have found to do this so far is to create a whole new form or create tabs. While those are all good and have their place. I know that I need to start breaking up my code into classes, I am developing a bad habit throwing everything into the MainWindow Class...
Here is the code if needed:
XAML:
<Window x:Class="ClockApp.MainWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
x:Name="MyWindow"
Title="Alarm Clock App" Height="180" Width="360" Visibility="Visible" ResizeMode="NoResize" WindowStyle="ToolWindow">

C Sharp :: Change Background In All Forms With Button Click
Jul 14, 2013I made 2 forms and Form2 has buttons with images like planets and game wallpapers etc. When I write the code for button:
this.BackgroundImage = new Bitmap(Properties.Resources._8_8008_by_amplifier404);
this.BackgroundImageLayout = ImageLayout.Stretch;
// where _8_8008_by_amplifier404 is name of the image located in resources
It only changes background in form which has those buttons as long the form is used. Once I go back to form1 it's changed to null. How to set background in all forms with a button click which will be there until another button with an image is clicked.

Visual C++ :: MFC- Receiving Button Click Message Failed
Oct 2, 2014I've created a new dialog in my MFC dialog based application. the new dialog contains 5 control buttons. The following happens and I don't understand why?
1. click on buttonX. (result ok, OnBnClicked message is sent)
2. click on on any place of the application, but not on the dialog.(removing focus from dialog)
3. click again on buttonX (FAILED, OnBnClicked message is NOT sent). but if instead I click on any other button in the dialog (result ok, OnBnClicked message is sent).
And when I do:
1. ...
2. ...
3. click on the dialog area just to set focus on the dialog again
4. click again on buttonX. (result ok, OnBnClicked message is sent)
**I need to do step 3 only if I want to click again on the buttonX! why?? I think it related to SetFocus() but I m not sure how.
I've tried different style like, tool windows, overlapped, popup. it happens in all the cases.
Code:
class CToolsDlg : public CBDialog {
DECLARE_DYNAMIC(CToolsDlg)
public:
CToolsDlg(CWnd* pParent = NULL); // standard constructor
virtual ~CToolsDlg();
CToolTipCtrl m_ToolsTips;

C# :: Using Lambdas With Events?
Feb 24, 2014I have a program that has been broken into View/Model/Control plus another class to handle RS232 output.
When the View requests something to be sent via RS232, an event is sent to the control, which then raises an event for the serial class.
Is there a way of using only one event without the serial knowing anything about the view?
If there was, I'd imagine it would be something with Lamdas.
C++ :: Creating Events And Registering To Them
Mar 16, 2014I want to build a library using c++ which will serve as an abstraction layer between applications and low-level process. The library will provide some APIs for the applications for some purposes.
For example the low-level process, may send an indication to the library i.e. raise an event, and the library in turns send it to all the applications, which have their registered callbacks to this library.
Any example for the previous scenario in c++ using boost library or the standard library will be perfect in Linux environment? The example that I want is: Generate event from a process and pass it to the library, then let an application register callback to the library.
Initially I know in Linux, I may use signal to send events, but my plan is to have a something more general not tighten to a specific OS.

C# :: Delegates / Events Are Just Not Sticking
Dec 28, 2014In my week long quest to understand delegates/events, all the contrived examples have made my understanding worse. I've been trying to make this simple console project work, where you have a Person, Phone and Switchboard class. My thinking was, that the Phone object would broadcast to any SwitchBoard that's listening, the SwitchBoard would broadcast to the proper phone on the other end and the phone would do the same for any person that's listening.
This is what I have so far, and after adding the SwitchBoard.
class Phone {
public delegate void IncomingCallHandler();
public event IncomingCallHandler IncomingCallEvent;
public delegate void OutGoingCallHandler(Phone p);
public event OutGoingCallHandler OutGoingCallEvent;

C++ :: Detecting Application Startup And Exit Events?
Apr 20, 2012I have written ( using VS2008 c++ ) a windows service which sends information about PC usage to a central database, as part of a PC availability setup. I have been asked to add the following functionality to it:
1) What applications are most used, when and how long for, and
2) What web sites are being accessed, again to find the most popular etc.
My main question is, what functionality is there to trap application start / close events from within my service ( just need the application name ), and secondly I am already using sockets to send information to a PHP script on a server, the best way to see what web pages are being accessed is to build in a packet sniffer, and extract the information from that.
Visual C++ :: Main CWnd Class And Mouse Events
Jun 17, 2013I have a main CWnd class called CMainWnd which is created like this:
Code:
DWORD dwStyle = WS_VISIBLE | WS_BORDER | WS_CLIPCHILDREN ;
...
CWnd::Create(AfxRegisterWndClass(CS_DBLCLKS), L"", dwStyle, rect, parent, NULL, NULL);
And I draw smaller windows on this main window with a CWnd-dervied class called CClientWnd, which is created like this:
Code:
DWORD dwStyle = WS_CHILD | WS_VISIBLE | WS_CLIPSIBLINGS | WS_BORDER;
...
CWnd::Create(AfxRegisterWndClass(CS_DBLCLKS), L"", dwStyle, rect, parent, NULL, NULL);
In the main window I draw lots of background stuff using a memoryDC and BitBlt(). In the child window, I actually am not drawing anything, I just created it to have events like mouse over, etc. In the child window when the mouse is over the window I bring up a pop-up window. This works unless my mouse is over any parts where something is drawn in the main window, then the popup just flickers constantly. Why is the main window affecting my mouse over events if I am not handling any such events for it?
C++ :: Program To Print Out X / Y Click Coordinates?
Jan 16, 2013I use the AS/400 warehouse system, and I need to be able to automate typing one letter in several different locations to speed things up.
My thoughts are:
1. Find out how to make a program that will determine x, y coordinates of mouseclicks, and then use software to use macros to change information.
2. Build a program that will complete a single process by repeating set mouse clicks and keystrokes.
We recieve HUGE transfers from a warehouse across the country, and have to change the first character of the name of bin locations - and after a few pages it gets VERY tedious.

C# :: WPF Databound ListView Item Click Event?
Aug 27, 2014I was using the same item click event on another listview, and it worked perfectly... I don't know why this is happening, but here's my problem:
When I double click on an item, and try to obtain its index in the listview, the items index always comes back as -1... Obviously -1 isn't an index, and I'm guessing that it is returning -1 because that item does not exist on the listview, but from what I'm seeing, it is impossible for the item not to be inside of the listview...
Here is the xaml for my listview:
<ListView x:Name="lstBookmarks" HorizontalAlignment="Left" Height="250" Margin="10,10,0,0" VerticalAlignment="Top" Width="327" ItemsSource="{Binding Bookmarks}">
<ListView.View>
[Code]....
When I uncomment the MessageBox, it shows -1... This is obviously not right lol. I have the same exact click event in another class, and I obtain the items index the same exact way.. The only difference between this listview and that one is that this listview is databound.. Is that the issue? If so, how does one overcome it?
