Closing form while processing
Hi
I have a while loop in a win form code. Also a close button on the form
calls Me.Close. How can I let the user close the form using the close button
even though the loop is still running? Right now pressing Close button waits
for loop to finish and then closes the form.
Thanks
Regards

DataGridView - Change selection color when focus lost
(I had posted this in the C# group and then found this group which I think is more appropriate)
I realized tonight that the DataGridView doesn't support a different selection color when it doesn't have focus. After
realizing this I set out on what I thought would be a quick and simple task to solve the problem.
Granted I'm no DataGridView expert, but to me this seems like it should work a...

Scrolling control under mouse cursor
I'm looking for a way to smoothly scroll the control under the mouse cursor
(not necessarily part of my application). I'm using C# with WindowFromPoint
to get the handle, and I've tried SetScrollPos and ScrollWindowEx without any
success. I'm simulating mouse wheel events right now, but this only scrolls
the active window and doesn't allow horizontal scrolling except in Vista.
Also, i...

GUI Like VS
Hello all, I was wondering how you go about designing a GUI like visual
studio. What I am looking for is the ability to pull a window out of the
main GUI and then be able to drag it back to the GUI locking it back into
place, similar how you can move the properties and solution explorer around.
Are there any examples out there? If so can someone please point me into

wpf font scaling
I have an area where I want to have some text displayed with the largest font
possible but the scaled text should be no larger than 300 wide and 50 high.
I was wondering what is the best way to do this in WPF.
I know pre-WPF you would do something like this:

Trapping KeyDown Events
I have a complex control based on a UserControl that is largely a graphical
rendering of data. While a user is viewing this data I would like to respond
to certain keyboard events.
(PageUp, PageDown, Home, End, ArrowUp, ArrowDown)
Since the control is mouse driven by "clicking" on various regions, there
are no controls contained that capture the focus.
The built in KeyDown event ap...

Enlarge image on mouseover (.NET 2.0)
I'm trying to create a smoothly animated doubling in size of an image when
the user moves the mouse over it and shrinking back to normal when the mouse
leaves. The image needs to enlarge/shrink while staying centered, NOT pinned
to the top-left corner. With WPF this is apparently only a couple lines of
XAML code but I'm at a loss so far in doing it efficiently and cleanly in
..NET 2.0.

Pasting HTML text doesn't work in Firefox
I need to copy a piece of HTML to the clipboard. I'm doing this
DataObject clipData = new DataObject();
clipData.SetData(DataFormats.Html, true, html);
Clipboard.SetDataObject(clipData, false);
If I paste, it works fine in any HTML edit box in Internet Explorer
and Chrome but it doesn't work in Firefox. Should I use another
format? What's the problem with it?
Thanks.

multiple occurences of HandleCreated for a single control

The events will be raised in the UI thread using the ISynchronizeInvoke
interface implemented by WinForms controls
I can’t register to the event at the constructor because it will allow
calling the event handler before the control is fully created. during which
calls to ISynchronizeInvoke are not allowed.

How to design I2C communication functionality

I have a question about how to design my classes in the following situation:
I have a communication port. It connects to an I2C bus. Through this port I

Richtextbox: how are pictures stored?
I'm using the RichTextBox component to store formatted text and
pictures. I noticed that inserted pictures are always stored as WMF,
that causes the size of the generated RTF to become very big.
Is there a way to use an alternative way to store pictures (for
example, in JPG, PNG or GIF) instead of bitmap?
Thanks.

Where to put code to have it execute only when form actually comes up (i.e. is visible)

code includes code that shows a status form indicating processing
activity, a form that immediately closes once the processing activity
is completed. I can't call it from the Load event as it will execute
before the form is visble. Where is the best place to put code like
this? I thought that perhaps the place would be in t...
