messagebox

问题 I would like to know how to use a YESNOCANCEL MessageBox in conjunction with IF logic from LogicLib.nsh in NSIS installer scripting to avoid having to use labels and gotos. Is there any way to capture the result of a MessageBox in a variable of some kind? Also, I know there are better things than NSIS out there, but using something else isn't a possibility at this point. =( Note the {WHAT GOES HERE??} in the below code. If this was just an If...Else... it would work fine. Thanks for the help

问题 I am using WPF NotifyIcon to create a System Tray service. When I show a messagebox, it shows up for half a second and then disappears immediately without waiting for input.

问题 ...and it makes no sense why. T-T In my Application_Startup event handler I have code that looks kinda like this: private void Application_Startup(object sender, StartupEventArgs e) { string errorMessage; if(CheckStartUpConditions(out errorMessage)) { (new MainWindow()).Show(); } else { MessageBox.Show(errorMessage, "Application Startup", MessageBoxButton.OK, MessageBoxImage.Error); Shutdown(); } } private bool CheckStartUpConditions(out string errorMessage) { errorMessage = string.Empty; if(

问题 With this the default is OK. Can I make the default Cancel? MessageBoxResult result = MessageBox.Show (message, caption, MessageBoxButton.OKCancel); 回答1: Use this overload, which allows you to specify the default MessageBoxResult: MessageBoxResult result = MessageBox.Show (message, caption, MessageBoxButton.OKCancel, MessageBoxImage.Information, MessageBoxResult.Cancel); 来源： https://stackoverflow.com/questions/7179900/wpf-messagebox-default-to-cancel

问题 Some of our non-technical users are having problems where a dialog MessageBox in our application can sometimes be displayed behind the main form and the application does not accept any input until the messagebox (which they can't see) is dismissed.

The Application does

问题 I need to change the message box location. I don't want it to be in the center of the page. MessageBox.Show("Hello"); 回答1: Normally, you can't change startup location of standard message box.
