View 1 RepliesApplication Does Not Return From Call To System.Windows.Forms.Application.DoEvents?
Aug 2, 2011I have a windows forms application written in VB.NET which scrapes information from serveral web pages (who doesn't right)? Anyway, I am having problem with one particular site where partway through the page navigation my application hangs. When I press pause (or break) in the debugger, it stops on a call to System.Windows.Forms.Application.DoEvents.
Resuming execution shows that it really is stuck on this line (it does not reach the next line of code). It also hangs about the same point each time I run it (at least its consistent). Since System.Windows.Forms.Application.DoEvents yields to other threads on the same processor and then resumes execution of the current thread, I think the problem is that some other thread is not behaving well (not returning from some event handling code). I thought Windows 7 was pre-emptive, which makes me
doubt that theory but I really don't know.
[Code]...
The program scrapes somewhere between 12 and 14 pages before it gets stuck on the call to DoEvents. Does anyone have a clue why this would happen? Why would any call to DoEvents hang?
.net - Best Use Of System.Windows.Forms.Application.Run()?
May 18, 2010i Have a programa that has starts in a main sub, it executes some code and after that code it opens a form using
System.Windows.Forms.Application.Run(General)
General is a form but also a class, so I wonder what it the pros or cons of using :
System.Windows.Forms.Application.Run(General)
vs
Dim gen as general
System.Windows.Forms.Application.Run(gen)
In the first I am opening a form using the name of the class, and I read that it is best to declare the instance as an object variable.

Forms :: Create A System Tray Application (service)?
Feb 16, 2009I'm wanting to develop what I perceive to be a pretty simple application. I want something that runs in the system tray that tests for the presence of a particular file on a network drive. If the file does not exist, the icon in the system tray is a green circle (like a traffic light).If the file DOES exist, then the system tray icon is a yellow circle (caution), until the user clicks it (the yellow system tray icon), and a record is written to another file, then the system tray icon changes to a red (stop) circle until that first file we tested for is gone.I'd also like to create "balloon messages" to go with the changes in the system tray icon.

C# - Stop Developers From Calling System.Windows.Forms.Application.DoEvents()?
Mar 15, 2009We just spent 300 man-hours fixing a buggy application in the field. It all came down to calling Application.DoEvents (re-entrancy problem).This was not caught in design reviews, code reviews.The code was inserted two years ago with the first version; the application was always "flaky" but recent changes exposed the re-entrancy problems to a greater degree. This incident is the second time in our organization that Application.DoEvents caused failures and multi-man hours of debugging.It was discovered in this case by simply noticing the call,buried way down in a complex event handler for an asynchronous task.What do you suggest to prevent this issue from happening again:
Add checkin gates to source control?
Developer training?
Code Analysis rules (why is this not already a built-in rule?)
How to I enforce a coding practice?

'System.AccessViolationException' Occurred In System.Windows.Forms.dll Immediately Before Entering A Click Handler?
Oct 20, 2010Win7 64 bit; fully patched VS2008 targeting FW2.0; VB.Net; running in Debug Mode (not tested in Release mode)I have a resonably complex app which I am refactoring a bit. As part of that, I relocated some code from a subroutine into a Click Event Handler. The Event Handler will, late in the handler, call the, reduced in function, subroutine. The point of this is thatNow when I click the button associated with the modified Handler I get:A first chance exception of type 'System.AccessViolationException' occurred in System.Windows.Forms.dll<br />With Error System.AccessViolationException Attempted to read or write protected memory.This is often an indication that other memory is corrupt.
