Hi!
I want to disable a windows close button.
Instead when the user presses the close button i want the window to hide (and not close) and the tray icon to appear.
The window hiding and the creation of the tray icon part is OK and works. (I tested this by calling those thing when I press a user button inside the form.)
Using FormClosed (occurs after the form is closed  not good) and FormClosing(occurs before the form is closed) events doesn't seem to work. Can anyone give a suggestion.
Thanx

Hi,
Setting e.Cancel=true inside the Closing event handler did it for me (it cancels the
Close action that starts with a Closing event and, if not cancelled, ends with a Closed event.

Hello!
How to create a application, that is stucked to the desktop? Is there any opposite of "always on top" like "always on bottom"?
Maybe you can help creating apps stucked on the desktop!
Thank you very much.

Yes. You can use P/Invoke to call SetWindowPos()[^] with HWND_BOTTOM.

Using SetWindowPos with the HWND_BOTTOM will just put the window behind all others but it is not the opposite of the HWND_TOPMOST flag as it isn't "sticky".

True. SetWindowPos() will need to be called repeatedly (eg: in a timer handler).

I have this Windows app.
When the user clicks on a button (any button), after the event handler is done, the form is supposed to have focus returned (like if there's a MessageBox involved).
However, I've noticed that the user is forced to click once on the form to regain focus.
To illustrate (and this sounds weirder)...
The user hits a button, a MessageBox appears saying "are you sure?", and the user hits "no".
The messagebox disappears. But the button still has focus (understandable). If the user clicks on a different button, that same button still has focus and Windows thinks the user just clicked it instead of the other button that they clicked. The user has to click once on the form (even though the form visually seems to have focus, with the title bar dark blue and everything) before clicking on any other button.
Any ideas? This one really has me stumped.

Wouldn't you know it, almost right after I post this, I found it. I had the button's Validated event also pointing to the Click event handler. Now it works fine. Thanks anyway!

I have a method which is run as a thread and at the end of it I have:
XtraForm2 form2 = new XtraForm2();
form2.Show();
and the thing is that the windows just flashes - opens and imidiately closes
how can I solve it??
|
|

Keep the thread alive while the form is shown. Easiest way to do this is probably use form.ShowDialog() rather than form.Show().
p.s. make sure this background thread is STA, or you will run into all kinds of odd problems.
|
|
|
|
|
hmm... I've tried ShowDialog() but the result is the same
I can't really get the idea of STA
I have a method
public void GetData(Object o)
{
...
}
which I'm starting from a button as a thread:
Thread wat = new Thread(new ParameterizedThreadStart(GetData));
wat.Start();
where the STA should be put?

STA indicates that the COM threading model for an application is single-threaded apartment.
Apply this attribute to the entry point method (i.e. the Main() method). It has no effect on other methods!

a did somethling like this in my XtraForm1.cs
[STAThread]
public void GetData(Object o)
{
...
...
form2.ShowDialog();
}
but again it closes itself :/
I also have in the Program.cs file:
[STAThread]
static void Main()
{
Application.EnableVisualStyles();
Application.SetCompatibleTextRenderingDefault(false);
Application.Run(new XtraForm1());
}
|
|
|
|
|
Try this:
Thread wat = new Thread(GetData);
wat.SetApartmentState(System.Threading.ApartmentState.STA);
wat.IsBackground = false;
wat.Start();
...
void GetData()
{
form.ShowDialog();
}
Let me ask you a question, though: why are you creating a new thread to create the form? You're creating lots of extra work for yourself by creating a new thread to launch the form. If you keep all the UI controls created on the same thread, things will be much easier for you.
Thus, I recommend you create all your UI controls on the same thread.

you solution works just perfect  thanks
the application looks like this:
I start it, and there is a button which is pressed and then the method GetData is started as a thread and after it processes all the data a second window pops up with a report, so I don't make a new thread for the second window

greetings for all, I am very instered in learn how work with sound in c#...
for instance load a music file, see the frequency of that, if any one have any idea or better have a project as example, please tell my,
regards
my;)

I believe in .NET 2.0 their is a System.Media namespace that has classes to handle wav sound files. If you are using .NET 1.1 or before (or if the classes in the System.Media namespace can't help you with your specific file format) then you might try using activeX controls. I know Windows Media Player has a control for video, but I am not sure whether they have a control for audio.
Now that I think of it, I remember somewhere on this site their is an article on audio output using Windows Media Player. Try searching.

To just play a file, using Windows Media Player as a control works best. To work with sound directly, you need DirectSound, part of the DirectX libraries.

yes as you know, all word that we say, more or less, have a average in a frequency scale, but not wory, indeed I star now a project for do many things using this topic "sound", when I finish this a post that...

If you just want to play WAV sound files, you can use System.Media.SoundPlayer. If you want to do advanced things like changing the frequency of sound files, you'll need to go outside the .NET framework for that. You can use DirectSound, part of DirectX. You could probably also use DirectShow, which is part of the PlatformSDK. There are DirectShow wrappers for .NET on this site if you care to search the articles.

You can also "execute" a sound file (as if double clicked in Explorer), using the
Process class;
please see the many messages that have popped up about this on these message boards...

Hello,
I have several MDI child windows for my application. These show up in the Windows list dropdown menu when I open them. When the user clicks on the X to "close" the child window, I just want to hide it so I capture this in my FormClosing event handler for each of them doing this:
if (e.CloseReason == CloseReason.UserClosing)
{
e.Cancel = true;
Hide();
}
Which hides the child window just fine, however, when I want to redisplay it, clicking on the appropriate control to call Show() for that window, it displays just fine but I don't get an entry in my Windows list dropdown menu for that item.
Any thoughts?
Thanks,
Matt

How do they get into your drop down list to start with ? That's obviously where the problem is.
