MessageBox.Show() freezes execution : windows form c#

阅读更多关于 MessageBox.Show() freezes execution : windows form c#

问题 Good day. I have a form and one backgroundworker . In the bw_Dowork event, there are instances when I need to print a message using MessageBox.Show()(i.e YES?NO box). However, whenever I call the messageBox.Show() method, the execution freezes and the form does not allow me to click my selection (i.e either Yes/No). Sometimes, if I want to work, I have to click fast as the message shows. Otherwise it freezes when I give a seconds of gap. Example of an instance where I use MessageBox.Show() is

How can I supress Delphi DataSnap error message dialogs?

阅读更多关于 How can I supress Delphi DataSnap error message dialogs?

问题 We run a DataSnap Delphi 2009 application on Windows 2003 Server. DataSnap Client and Server are on the same computer, using DCOM over Borland Socketserver. The client runs a background batch job. Sometimes, we discover that the client can not connect to the server application and displays a message dialog on the server desktop indicating for example "Could not connect to server. Network path could not be found." or "Objectexporter not found." Our Delphi client code never uses a message

Tkinter tkMessageBox disables Tkinter key bindings

阅读更多关于 Tkinter tkMessageBox disables Tkinter key bindings

Here's a very simple example: from Tkinter import * import tkMessageBox def quit(event): exit() root = Tk() root.bind("<Escape>", quit) #tkMessageBox.showinfo("title", "message") root.mainloop() If I run the code exactly as it is, the program will terminate when Esc is hit. Now, if I un-comment the tkMessageBox line, the binding is "lost" after closing the message box, i.e. pressing Esc won't do anything anymore. This is happening in Python 2.7. Can you please verify if this is happening also to you? And let me know about your Python version. Here is a way to "by-pass" the problem. It's a

MessageBox with custom font?

阅读更多关于 MessageBox with custom font?

Is there an easy way to display a custom font for a MessageBox? For "easy way" I mean using WinAPI or other techniques but not coding a entire messagebox from scratch. I've seen lots of custom messagebox but most are just forms which don't preserve default messagebox additional parametters, other custom messagebox just has their size/bounds wrong so the "ok" button is cutted or not right alligned, and other custom messagebox has their own problems/bugs. I hope if is possibly to add a generic parametter to instance this great custom messagebox setting the desired font: The original code is a C#

NSRunAlertPanel shows up behind the “active window”

阅读更多关于 NSRunAlertPanel shows up behind the “active window”

I'm trying to put together a simple error reporting package. If my main program crashes, it saves a crashlog, then starts a reporter program. The reporter program asks the user if it can send the crash log to me, then does so. I'm using NSRunAlertPanel to create a basic message box. For some reason, that message box is showing up buried underneath any other windows that may be open. Run the main package from a Finder window, it shows up on top, force it to crash, the reporter window shows up behind the Finder window. Why is this happening, and how can it be solved? Minimal test case: #import

How can I get MessageBox icons in Windows 8.1

阅读更多关于 How can I get MessageBox icons in Windows 8.1

问题 I want to get the MessageBoxIcons, that get displayed when the user is presented with a MessageBox . Earlier I used SystemIcons for that purpose, but now it seems that it returns icons different than the ones on the MessageBox . This leads to the conclusion that in Windows 8.1 SystemIcons and MessageBoxIcons are different. I know that icons are taken using WinApi MessageBox, but I can't seem to get the icons themselves in any way. I would like to ask for a way of retrieving those icons. 回答1:

Replacement for yes/no/cancel MessageBox (C#)

阅读更多关于 Replacement for yes/no/cancel MessageBox (C#)

问题 I am looking for a decent replacement for the standard windows YES/NO or YES/NO/CANCEL MessageBox. I have often seen these standard dialogs misused in ways such as: "To save in plain text answer YES, or to save in html answer NO". Obviously, the text should read "Save As: and the "buttons should be labeled "Text" and "HTML". It is not a yes/no question that is being asked, and although it could be phrased that way, it would not be easy to read and understand. Microsoft gives no way to change

How is this causing an endless loop?

阅读更多关于 How is this causing an endless loop?

问题 Some legacy code I'm stuck maintaining is stuck in an infinite loop (and thus I myself seem to be in one); I can't figure out why/how, though. Here's the app's entry point, where it instantiates the main form (frmCentral): CODE EXHIBIT A public static int Main(string [] args) { try { AppDomain currentDomain = AppDomain.CurrentDomain; currentDomain.UnhandledException += new UnhandledExceptionEventHandler(GlobalExceptionHandler); string name = Assembly.GetExecutingAssembly().GetName().Name;
