Hi,
you can read all bytes of all files you can access.
and you can write these bytes again to any location you can access.
Since .NET 2.0 you can do it with File.ReadAllBytes and File.WriteAllBytes,
you don't need streams for that.
Don't really know what good it all will do for you tho. You probably will
not be able to understand the bytes, nor change them in any way that
results in a valid new document. And you can't just convert a document
by changing its file extension, if that were what you hope for.

Hi All,
I have got a problem in events. I have a treeview Before_Select event and one is Panel_leave event
so when i m on panel and i click a treenode the Panel_leave is executed but Before_Select doesn't execute .But if i make a break point in Panel_leave it works and if i remove break points it doesn't work.
Please help in solving this problem , I think i need thread Synchronization , but i don't know how to do it.
Thanx.

Hi,
the events go to the active message pump, that is the GUI trhead of the
currently active window (which normally means: the main thread for all windows).
So Panel_leave and Before_Select normally get handled by the same thread,
that will not be the problem.
Are you sure Before_Select does not fire? How did you figure that?
Best way is: add log statements such as log("begin of Before_Select");
and provide a log method in every interested class, e.g.
public static void log(string s) {
s=DateTime.Now.ToString("hh:mm:ss.fff")+" "+s;
Console.WriteLine(s);
}
If however you try to manipulate some controls from inside another thread,
then you must use Control.InvokeRequired property and Control.Invoke() method;
if not, all kinds of strange things may and will happen.

Hi!
I have something like this:
public class MyApp: System.Windows.Application
{
public MyApp()
{
m_Window = new Window();
}
Window m_Window;
}
and it gets instantiated from:
class Program
{
[STAThread]
static void Main()
{
MyApp app = new MyApp();
app.Run();
}
}
Every time someone says m_Window.Close() the whole application gets terminated ( = also 'app' gets terminated).
But that is not what I want, I want only to close m_Window ( = 'app' should keep running).
So, where did I go wrong?
Thanks,
Mario M.

It Works when I derive MyApp from System.Windows.Window but it looks quite ugly:
public class MyApp : Window
{
public MyApp()
{
this.Visibility = Visibility.Hidden;
m_Window = new Window();
}
Window m_Window;
}
class Program
{
[STAThread]
static void Main()
{
Application app = new Application();
MyApp win = new MyApp();
app.Run();
}
}

m_Window.Close() is different than Visibility.Hidden now isn't it.
In the first case, yes, the application will terminate because the form has been closed, thus terminating the message loop. In the second case the window is not closed, just hidden, so the message loop continues and the application does not terminate.

So what's your point?
In the first case I derived it from 'Application' and in the second I derived it from 'Window'.
But I don't want to derive it from 'Window' because it is no window.
|
|
|
|
|
The point is, learn the difference between window.close and window.hidden
only two letters away from being an asset

How about looking at the two DIFFERENT code samples I posted?
In the first snipped I create an App that has a window as member (only one window). When the window gets closed also the app terminates.
And in the second sample I create a hidden window that has an additional window as member (two windows). I don't say: m_window.hidden! I hide the parent!
But I think creating a hidden window just to make sure that the class itself survives when one of its members gets closed is quite ugly.
So, please have a look at the code first, before you start getting wise!

Hi,
a normal window app has an Application.Run(new Form1()); in its static main method.
The Run method will show the Form1 instance (and run a message loop to do that),
and it will return when the form gets closed or Application.Exit() gets called.
as an alternative you can call Application.Run(); without arguments;
that one will start a message pump and return when Application.Exit() gets called.
Hope this helps.

"as an alternative you can call Application.Run(); without arguments;"
yeah thanks, but I think taht is what I showed already in my first posting.
Maybe I should try it verbally:
1.) I want an application that instantiates a class
2.) This class should open a window
3.) When the window gets closed the class should stay 'alive' (and therefore also the application must not get terminated)

Hi,
one way of doing that is:
- create a Windows app with a main form
- hide the main form (it initially might have served as a splash screen)
- create another window/form/whatever, maybe inside the main form's Load event
- do whatever you want with that window/form/whatever, closing it does not
affect the (invisible) mainform, hence the app continues (doing what I might ask).

Forget it, I'll take the "derive from Window" approach

Problem solved:
[STAThread]
static void Main()
{
Application app = new Application();
app.ShutdownMode = ShutdownMode.OnExplicitShutdown;
MyApp win = new MyApp();
app.Run();
}
class MyApp
{
public MyApp()
{
m_Win = new Window();
m_Win.ShowDialog();
}
Window m_Win;
}
}

What error do you get?

I doubt he has any code. Look at his previous posts.

Hello J4amieC,

Maybe, but it leads to nothing!
Pointing it out every time will only bring bad spirit to the forum!
Only think of the great Indian programers, who are doing excellent work, here in the forum.
I think I would be very pissed, if I would allways read about how ???? the Austrian's are.
Wouldn't you?
Apart from that it has nothing to search in a programing forum!
I would suggest to:
1) Try to help those people, if it's the first time they are doing mistakes. (By showing them forum guidelines)
2) Ignore, vote down or mark as spam, but not respond.
2.1) Because my feeling is, that these people have:
2.1.1) Big problems to articulate their needs.
2.1.2) Just have fun watching, how others are going crazy by reading their post! (Have you ever considerd this?)
But again, for me this has nothing to search at the C# forum.
All the best,
Martin
