If the document is on the disk, you can use Process.Start(Myfile.htm) on the file to start it. If it's not present, save it to a temporary file and do the Start on it. This will load your html file in the default browser, IE, FF or whatever.

Hi...
I have two forms in my windows application.
Form1 and Form2.
In Form1 I have 1 Label and a button.
In Form2 I have just a button.
When clicking on this Form1 button I am opening Form2.
In Form2 button Click event I have to hide the Form2 and have to show the value "HI" in the Form1 Label.
To do this some one suggested me use delegates. Is this only way to do this?
your

Hi.. 
you can do thats by connect even form .
--- Form1 ---
private void button1_Click(object sender, System.EventArgs e)
{
Form2 FRM = new Form2(this);
FRM.show();
}
public void SetLabelValue(string MSG)
{
Label1.Text = MSG;
}
--- Form2 ---
Form FRM1 = null;
public Form2(Form1 frm)
{
// Required for Windows Form Designer support
InitializeComponent();
this.FRM1 = frm ;
}
private void button1_Click(object sender, System.EventArgs e)
{
this.FRM1.SetLabelValue("HI");
FRM1.show();
}

This is a poor solution because it couples the forms together. If you want to change the way your application works in the future it will be more difficult to make the modifications.

Hi,
Could anyone help me to store a date in DateTime variable in the format of 'DD-MMM-yyyy'(my codebase is asp.net with c#).
For example;
DateTime dateTest;
dateTest=DateTime.Parse("02/14/2008");
The dateTest should provide o/p like 14-Feb-2008
Thanks in advance
John

A DateTime just stores the date and time. If you want it in fancy formats, just use the overloaded ToString(string format) method.

Hi, is it possible to get all the point inside the polygon. Scenario is quite simple; I have created a polygon on panel. Now I want to get all the points inside polygon. Can anyone tell me about any function (win32 or .net library function) or good web link, I will be thankful to you.
Regards,

You need all the points inside polygon? I am afraid but you will get OutOfMemoryException

Thanks a lot for you reply. Actually I want to check the mouse enter event for the polygon, I found two ways to check it
1. Check all the polygons coordinates and on mouse move and pick up the source polygon
2. Create a Hashtable of point and their respective polygon object. On every mouse move check that hash.
I found 2nd method fast and efficient. I don’t think so it may cause out of memory, what u suggest! Please guide me about the good approach that I should fallow.
Regards,

Hi,
Maybe this is what you need:
.NET has a Region class that represents an arbitrary closed shape.
And Region.IsVisible() tells you whether a point, rectangle, whatever lies inside
the region.
BTW: if yours happens to be a web app, then PolygonHotSpot Class might be useful.

Hi, it is really great solution, but I don’t think it will work for polygon....

Why not? Have you tried? What was the result?

I tried it and it is really working fine. It is good solution. You have really solved the looping cost of my program. Thanks a lot.

Hi Guys
I finnaly got the label.text to scroll (threading issue)! Now ive come across two other issues
1) is there some way i can check whether all the text in my label is displayed? The point is to only scroll the text if the labels size isnt big enough to show it all.
2) when the label is too small to show all the text and it scrolls it doesnt disply half words... (hope that makes sence) it will wait until theres enough space at the end before displaying the next word. So is there a way to make it kick this habbit cuz its making the text jurk every time a new word comes out? i want it to display the half word at the end cuz it scrolls and the rest of the word will be displayed eventually
thanx peepZ

You can use MeasureString on the graphics class to find out how big a string is with a given font, then compare with the label size.

Hello,
This[^] article will give you an idea how to use "MeasureString" of the Graphics object.
It also shows you the usage of "DrawString" which you could use in your own LabelControl, to be more dynamic.
All the best,
Martin

heres what i got
public partial class StatusBar : UserControl
{
Graphics g = new Graphics();
public void scrollText()
{
if (g.MeasureString(Message, lblMessage.Font) > lblMessage.Width)
{
}
else
{
}
}
}
the errors i get is
1) The type 'System.Drawing.Graphics' has no constructors defined
2) Operator '>' cannot be applied to operands of type 'System.Drawing.SizeF' and 'int'
i get why 2) is wrong cuz g.MeasureString() returnes 'SizeF' and im trying to compare that with int. how ever i dont get why 1) moans?
any ideas on how to rectify this?
thanx

Hello my quick friend,
You get the Graphics object of any Control for free in the OnPaint method.
If you inherit a control you can overridfe the OnPaint method and use the Graphics object of the passed args.
I show you an example where I inherited from Forms.Label:
private bool testsize = false;
public void TestSize()
{
testsize = true;
Invalidate();
}
protected override void OnPaint(PaintEventArgs e)
{
if(testsize)
{
SizeF actSize = e.Graphics.MeasureString(Text, Font);
if(Width < actSize.Width)
{
MessageBox.Show("Error: label to slim");
}
testsize = false;
}
base.OnPaint (e);
}
You can start the test from outside by calling the "TestSize" method of the Label
Hope it helps!
All the best,
Martin

you rock dude!
i got it working by using the OnPaint method to check wheather its necicary to scroll and the my scroll() only does the deed if the flag is true!
thanx so much!
