I haven't laughed that hard in a while. I love the comments explaining the steps.

You forgot to use the ToLower method on the string before parsing it.
You should use double.Parse instead of int.Parse, use Math.Round on the result, and then cast it to an int.

That's really, really bad. If you use the literal value true in the trinary condition statement, it will be optimized away. You have to put the true value in a variable and use in the statement.

One way, with code is
this.Width = x; (x being some number that you want to size) (or, with that, by modifying the entire size) Another way is, in the designer, go to the properties of the form and change it. Simple... I don't know about console though. 
The most knowledge doesn't mean the most wise...

change the height & width property of the form

You should also grab a book for C# if you don't know this... I recommend the Dummies for Visual C# 2005. It's good for beginners.;)

How do I use Debugger.Log( )?
I want to write a debug message to the console. The application is a C# console app written under the VS 2005. I do not want to rely on the VS IDE to see the message.
The following code doesn't write to the CMD Console when I run it. Why? How do I use Debugger.Log()?
using System;
using System.Collections.Generic;
using System.Diagnostics;
using System.Text;
namespace ConsoleApplication {
class Program {
static void Main(string[] args) {
try {
DateTime dtBadDate = new DateTime(2007, 9, 31);
}
catch (Exception ex) {
Debugger.Log(1, ex.Source.ToString(), ex.Message.ToString());
}
}
}
}

You need to use Console.WriteLine[^] or one of the Write methods.
Debugger.Log is output to Visual Studio's Output window, or you can attach a custom listener.
Take care,
Tom

Excellent. Thank you. It makes sense now why I can't see the output.

Hello to all.
I have a function that according to some criteria creates zedGraph curves for display in a graph.
the function is as follows(cut):
private void createCurves(ZedGraphControl zgc)
{
ColorSymbolRotator rotator = new ColorSymbolRotator();
#region create curves as needed
for (int i = 0; i < lgControlsPanel.Controls.Count; i++)
{
if (lgControlsPanel.Controls[i] == angleCheckBox)
if (angleCheckBox.Checked)
{
foreach (string key in valveCheckedListBox.Items)
{
if (valveCheckedListBox.CheckedItems.Contains(key))
{
zgc.GraphPane.AddCurve(key + ": Angle", anglePointArr[HexToLong(key)], rotator.NextColor, rotator.NextSymbol);
}
}
}
.
.
.
zgc.AxisChange();
}
The problem I encounter is that if I call this function from the main thread that craeted the form
on which the zedGraphControl is placed, everything is going fine.
BUT, if I let a new thread handle it, it does all operations fully but isn't refreshing the graph
view until I live the form and return to it.
only then do I see the changes.
here is my new thread call:
<br />
Thread startCreateCureves = new Thread(delegate() { createCurves(zgc); });<br />
startCreateCureves.Start();
of course I tried already to use invoke method and refresh with no luck:
private void createCurves(ZedGraphControl zgc)
{
if (zgc.InvokeRequired)
{
createCurvesHandler d = new createCurvesHandler(createCurves);
this.Invoke(d, new object[] { zgc });
}
ColorSymbolRotator rotator = new ColorSymbolRotator();
#region create curves as needed
for (int i = 0; i < lgControlsPanel.Controls.Count; i++)
{
I also tried it with: this.Invoke(), and NADA.
can someone please explain to me the weird phenomenon?
thanks in advanced.

Hi again,
this is similar to your previous topic:
1. yes, when not running on the thread that created the Control, you must use
Control.InvokeRequired and Control.Invoke()
2. the thing your thread is not allowed to do should be in the ELSE part of the
if(Control.InvokeRequired) which means it does not execute on the
wrong thread, but it does execute on the right thread. The way you wrote it, it
would be executed twice.
If this wrong way of doing Control accesses does not throw an InvalidOperationException
(with some "illegal cross-thread operation" message) it indicates that you (or your
Control provider):
- either are running on an older .NET version (1.0 or 1.1), if so, why?
- or have done something to suppress exceptions (e.g. set Control.CheckForIllegalCrossThreadCalls false, very bad idea)
- or have done something to ignore exceptions (e.g. an empty catch block, very very bad idea)

HI,
I didn't do any action to suppress any thing. in every other case I do get these
exceptions, only in this case I do not.
I don't know why it's like that.
but the most peculier part is that if I leave the form and then return to it,
I can see the changes made, and they are correct.

Hi,
this may indicate that you should Invalidate() the ZedGraph Control as Patrick suggested.
And maybe they did set CheckForIllegalStuff=false internally!?

There's only one thing missing from your code:
You need to be calling zgc.Invalidate() or zgc.Refresh() after calling AxisChange(). It won't repaint anything until something tells it to; this is one of the ways ZedGraph maintains performance. It doesn't refresh willy-nilly. All the AxisChange() call does is cause the ZedGraphControl to recalculate what the axis limits SHOULD be; it doesn't cause the control to actually display them.
So all you have to do is call Refresh() on the control  Your threading looks fine. You need that Invoke() there if you're going to be running the code on a separate thread. You should call "return" inside that if() statement after calling Invoke() though, otherwise it will continue to run the code below, as Luc pointed out.

where do I call the zgc.Refresh() or invalidate?
right after axischange() in the same thread like this:
private void createCurves(ZedGraphControl zgc)
{
if (zgc.InvokeRequired)
{
createCurvesHandler d = new createCurvesHandler(createCurves);
this.Invoke(d, new object[] { zgc });
}
else
{
ColorSymbolRotator rotator = new ColorSymbolRotator();
#region create curves as needed
for (int i = 0; i < lgControlsPanel.Controls.Count; i++)
{
if (lgControlsPanel.Controls[i] == angleCheckBox)
if (angleCheckBox.Checked)
{
foreach (string key in valveCheckedListBox.Items)
{
if (valveCheckedListBox.CheckedItems.Contains(key))
{
zgc.GraphPane.AddCurve(key + ": Angle", anglePointArr[HexToLong(key)], rotator.NextColor, rotator.NextSymbol);
}
}
}
.
.
.
zgc.AxisChange();
zgc.Refresh();
}

How can I programatically add/remove appletalk,ipx,tcp/ip protocols from network connection ?
This is a regulatory requirement for our network to allow only certain protocols.
Any help is god's grace

Do you mean how to create Network Conections only with these Protocols?
