Hi Everyone,
I'm very new to C# and I have the following problem - please help.
I have a Windows Forms application called 'FunApp' which has a status
bar. I also have a separate class library called FunTx compiled as a
DLL.
What I want to do is update the status bar from within a FunTx method -
and I used delegates to try this. Here's what I did.
FunApp
--------
delegate void SetStatusBar(vo id)
in a method of FunApp, I instantiated this
SetStatusBar sb = new SetStatusBar(Se tStatusbarText) ;
where SetStatusBarTex t is a method that sets the .Text property of the
status bar.
I do the usual stuff like
FunTx ft = new FunTx();
ft.FunProcess(s b,n);
FunTx (separate class library - DLL)
-----
in FunTx I have a method called FunProcess
public void FunProcess(SetS tatusBar sb, int y)
{
.....do something....
sb("And now update the status bar");
}
But nothing happens. No change in status bar. What am I doing wrong?
Any help (other ways to do too) is greatly appreciated.
thanks! 2 2121
Hi,
Your delegate seem to accept no parameters. How do you expect FunTx to pass
the updated message to be displayed on the status bar?
This line: sb("And now update the status bar");
should upset the compiler!

Hi Dmitriy,
Yes it did :) (after I posted the Q) because I was mistakenly not
compiling my class library. Anyway, now I'm lost - I don't know how to
do this. Is there some way I can accomplish this thru my class
library?

Hi,
I have a main form for my project. It uses a routine in another class to do
work on a file -- line by line. I'd like to have a text box on my form
display the lines, say every 5,000 -- so I can tell the progress. From what
LITTLE I know it looks like I'd have to pass the form to the class so that
the class can refer back to the form and update the textbox. It seems to me
that there must be a better way to handle this. Can anyone...

Ok, here's the scenario:
I have a form with a status bar on it.
I have a class that does a LOT of processing.
I want to update the status bar text property periodically from within the
class by passing a reference of the status bar to the class.
In VB6 this is pretty straightforward, but I just can't seem to get it
figured out in vb.net.
Should I be trying to do it this way in .net or what?

> bar.PerformStep ();
I noticed that there's a property for the bar stating what time
it should take for the animation to move the fill to the
requested spot. I'm guessing that's the time i should delay
my text updating by. Correct?
When you mentioned a delay - is there an other way to do
it than threads? I've found this solution.
