Hi All,
I need to run 3 methods parallaly.Then I have used Threading for that. Here is the code.
public void threadtest()
{
Thread SpecialThread = new Thread(new ThreadStart(this.GetSpecial));
Thread BulkThread = new Thread(new ThreadStart(this.GetBulk));
Thread NormalThread = new Thread(new ThreadStart(this.GetNormal));
SpecialThread.Start();
BulkThread.Start();
NormalThread.Start();
SpecialThread.Join();
BulkThread.Join();
NormalThread.Join();
while((NormalThread.ThreadState==System.Threading.ThreadState.Running) ||
(BulkThread.ThreadState==System.Threading.ThreadState.Running) ||
(SpecialThread.ThreadState==System.Threading.ThreadState.Running)
)
{
}
}
But most of time one or two threads are going to aborted or something happen and I loose their results.Sometimes this worked properly and I can get all results from 3 methods.
Can any one correct this code?

I get a HtmlDocument object from my application.
How to get the default webBrowser in OS,
and this webBrowser load the HtmlDocument object?
|
|
|
|

Not possible. The only browser you can interact with in C# AFAIK is IE, and certainly if FF has an interface, it won't be interchangable with the IE one.

how to open IE and load HtmlDocument object by my winform?
|
|
|
|
|
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?

Hello,
This article [^]from Colin Angus shows you all!

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.
