Wrap the update up with a BeginUpdate(), EndUpdate() block.

txt1.BeginUpdate() ? --> doesn't work

Not the textbox, but the whole update of your control.

Hey,
Do I have to import something for that? And what do you mean with the whole update of your control?
Do I have to make a new class, instance, interface? Our just:
BeginUpdate();
ApplicationDirector.Instance.removeCharachtersFromProgressScreen(lenghtWrittenString);
EndUpdate();
(but that doesn't work)

Say you have a progressbar control with the text on it (we'll call an instance of it superProgressBar), then you would normally do
superProgressBar.BeginUpdate();superProgressBar.Increment();superProgressBar.EndUpdate(); The Increment method would be responsible for updating the scroll bar and writing the text on it.
Also, you might want to consider setting up double buffering. Use the following
this.SetStyle(ControlStyles.AllPaintingInWmPaint | ControlStyles.UserPaint | ControlStyles.DoubleBuffer,true);

Class C
{
}
Class A
{
Private C;
}
Class D : C
{
}
Class B : A
{
Private D;
}
It comes to this that when I have a member of type B, I have also C and also D in it. How can I override C in it?
Thanks alot for the helpers
NaNg.

Use virtual keyword for C.

It sais "invalid modifier 'virtual' for C".
I'll try Explaining again...
I have these classes:
public Class C<br />
{<br />
<br />
}<br />
<br />
public abstract Class A<br />
{<br />
protected C;<br />
}<br />
<br />
public Class D : C<br />
{<br />
}<br />
<br />
public Class B : A<br />
{<br />
private D;<br />
}
When I do this: B = new B();, I have D AND C in B.
And I need ONLY ONE, which is the newer one - D.
How can I make the Class A use the new one (D) insted of the old one?

Can't you log the key presses?
You can make a buffer like this:
IF( a key is down add to buffer)
IF( THAT key is released remove from buffer)

Hello,
If you need it for your WindowsApplication, you could use the KeyDown event of your main form (KeyPreview has to be true).
this.KeyPreview = true;
this.KeyDown += new KeyEventHandler(CheckKeys);
private void CheckKeys(object sender, KeyEventArgs e)
{
if ((e.KeyCode == Keys.F1) && (e.KeyCode == Keys.RShiftKey) && (e.KeyCode == Keys.LShiftKey))
e.Handled = true;
}
If you want to log all keybord entries of your a computer, I think no one will help you here!
All the best,
Martin

I have an object where I do 'special' cleanup in case of exception
my code is somewhat like that:
void Method()
{
try
{
Something();
}
catch
{
SpecialCleanup();
throw;
}
finally
{
NormalCleanUp();
}
}
my problem is that when an exception is thrown VS break into the catch clause and I have no idea what causes the exception.
I also tried
catch(Exception ex)
{
SpecialCleanup();
throw ex;
}
but the ex.StackTrace is reinitialized and I have no idea of the problem!
any tips on how to to be able to debug that?
for now I wrote:
#if !DEBUG
catch
{
SpecialCleanup();
throw;
}
#endif
but I would like to catch meaningful stack trace at runtime as well....
|

Is there any return statement in "SpecialCleanup()" method also am assuming that the exception could be from SpecialCleanup() method only so you are not able to figure out what was the original exception.
I would suggest that you log the stack trace as soon as the exception is raised !!! Use exception handling block and logging block provided by MS ...

Assuming that you are creating a windows application, change your project settings to Console application (won't change anything in your programm, only you will have console window available for debugging purposes).
Check this:
try
{
Something();
}
catch (Exception e)
{
Console.WriteLine(e.ToString());
SpecialCleanup();
}
finally
{
NormalCleanUp();
}

You are running in to a problem known as "breaking the stack", which is why the exception doesn't have the relevant stack trace data. You were on the right track, but need to change the code so it looks like this:
catch(Exception ex)
{
SpecialCleanup();
throw;
}The difference here is that throw ex; throws a new exception where throw; re-throws the original exception.
That being said, you really should try to avoid catching general exceptions and catch specific exceptions that you know you can recover from. What is the difference between SpecialCleanup and NormalCleanup?

thanks for the tip, I'll try that tomorrow!
the relevant objectis an UndoManager.
in case of exception the special cleanup remove all action, i.e. there is no any undo action anymore.
This way, if someone cath up the exception higher the hierarchy he know he would be safe from corrupted undos... (there would be nothing left to undo!)

Try adding $exception to the Locals window.

hi,
thank u for u r response..
Error i am gettign is:
"The & character,hexadecimal vale 0x26 can't be included i a filename"
I am storing some values in an XMl file and i am passing Filename as parameter of a method.
Not by SaveDialogControl.
Through code. And if I give the correct file name it is saving as a xml file.
But if i give pass extra chracters to a file name through method.
It is giving errror like.
"The & character,hexadecimal vale 0x26 can't be included i a filename"

That is fine but my question is why to want to store a file name with special character as most of OS doesn't allow that !!!
