Hi Group!
I have a simple GUI featuring a RichTextBox and a Button. On Button
click, I start a BackgroundWorke r that performs a query on the database
firing a ProgressChanged Event for every row. The corresponding event
handler appends the row to the RichTextBox.
This works quite fine, but if I click into the TextBox while the
BackgroundWorke r is running, the TextBox gets blank and the GUI hangs
until the BackgroundWorke r has finished. As soon as it has, the TextBox
is updated again correctly and everything is fine again. If I don't
click into the TextBox, it does update and display correctly.
There are no event handlers whatsoever attached to the TextBox.
Any ideas?
cheers
Mathias

It sounds as though in your button click handler, you are waiting for the
BackgroundWorke r to complete.
If you are, then don't do that.
If you're not, then you should post a concise-but-complete sample of code
that reliably reproduces the problem. There's no way for someone to help
you fix your implementation without knowing what the implementation is.

Hi,
I am having some lock up problems in my c# code.
when from a 2nd thread (worker thread) i call a normal standard function
like Trace.WriteLine the 2nd thread freezes/hangs.
The 2nd thread is started with a normal threadstart, etc.
When looking on the internet I found some articles that hangs can be caused
by unmanaged threads but I don't think I am doing this (am not using coms,
.... )

Hi,
I am having a thread hang problem in my c# code.
The example on the website: http://csharp.web1000.com/ is a
simplified version of my problem.
You will see in the form that a method TestThread increments a number in the
textbox on the form.
TestThread is called from a worker thread (2nd thread) using a TimerThread.

I've created a pocketpc app which has a startup form containing a listview.
The form creates an object which in turn creates a System.Threading.Timer.
It keeps track of the Timer state using a TimerState object similar to the
example in the System.Threading.Timer documentation. The method which
handles the timer events, among other things, periodically calls a method in
this TimerState object which raises an event to the startup form,...

Hi all,
I'm having a weird time with a call to the Refresh() method of a
DataGridView. I have a VB.NET 2005 Windows application with a main form and
a "worker" thread. The main form delegates a Sub to the worker so that the
latter can refresh the DataGrid after updating the DataTable driving it.
When I run the app under the debugger, everything's fine. But when I run it
for real, it hangs, apparently in the Refresh() method of the...

Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
