mainwindow

I have an app in which the screen continuously is capturing in background thread. Here is the code - (UIImage *) captureScreen { UIWindow *keyWindow = [[UIApplication sharedApplication] keyWindow]; CGRect rect = [keyWindow bounds]; UIGraphicsBeginImageContext(rect.size); CGContextRef context = UIGraphicsGetCurrentContext(); [[keyWindow layer] renderInContext:context]; UIImage *img = UIGraphicsGetImageFromCurrentImageContext(); UIGraphicsEndImageContext(); UIDeviceOrientation orientation = [UIApplication sharedApplication].statusBarOrientation; if ((orientation ==

Im working on a WPF application. I have a label called "Status_label" in MainWindow.xaml . and I want to change its content from a different class (signIn.cs). Normally I'm able to do this var mainWin = Application.Current.Windows.Cast<Window>().FirstOrDefault(window => window is MainWindow) as MainWindow; mainWin.status_lable.Content = "Irantha signed in"; But my problem is,when I'm trying to access it via different thread in signIn.cs class, it gives an error: The calling thread cannot access this object because a different thread owns it. Can I solve this by using Dispatcher.Invoke(new

As mentioned before - I'm an Objective-C newbie of the first order but having read 4 physical books on the subject and a bucket-load of ebooks and documentation I still can't find what I'm looking for. I have a top-level content view controller that wants to configure its view property from the physical dimensions of the window property of the application delegate. This is something that several people have already asked questions on. ( [UIScreen mainScreen] doesn't cut it for reasons already aired many times before on this forum). Therefore, the logical approach would be for the content view

proc.MainWindowTitle.Contains("e") How does one get the window titles of all the current windows containing "e" open instead of just the Main Window using the "MainWindowTitle" and store them into a string array? EDIT: string[] toClose = {proc.MainWindowTitle}; for (int i = 0; i < toClose.Length; i++) { string s = toClose[i]; int hwnd = 0; hwnd = FindWindow(null, s); //send WM_CLOSE system message if (hwnd != 0) SendMessage(hwnd, WM_CLOSE, 0, IntPtr.Zero); HuorSwords Code snippet string[] result = new string[50]; int count = 0; Process[] processes = Process.GetProcesses(); foreach(var process

I'm new to qt programming so please don't mind if you find it a noob question. I've added a button to my main window but when I run the code the button is not displayed. Here's my code: mainwindow.cpp #include "mainwindow.h" #include "ui_mainwindow.h" #include <QtWidgets> MainWindow::MainWindow(QWidget *parent) { QPushButton *train_button = new QPushButton(this); train_button->setText(tr("something")); train_button->move(600, 600); train_button->show(); } mainwindow.h #ifndef MAINWINDOW_H #define MAINWINDOW_H #include <QMainWindow> namespace Ui { class MainWindow; } class MainWindow : public

I want to make my MainWindow a singleton because I want to make accessing it from all other windows in my app easier. But I couldn't make it run. Here is what I did. As usual, I made the MainWindow contractor private, and created a public static MainWindow Instance property to return a static instance. When I just run it without any other changes, I got "No Source Available" error. I googled the Internet and found one related topic at http://www.netframeworkdev.com/windows-presentation-foundation-wpf/xamlc-singleton-class-80578.shtml . However, I couldn't make it work as suggested there. Some
