Is there any way to declare global variable in c# that can accessed by all class of application ??

Anti-OOPs. 
Use a static class that should be befitting your bill/requirement.

|
|

public static variables will do the trick;

There are no global variables in C#. You have to put the variables in a class.
You can make a static class with public static variables in it. Those are accessible from anywhere in your application. Also, it's obvious that the class is intended for this, as you can't create instances of a static class.

how can you make a static class?
and what is partial class?

Create a class and make it static...
Example:
public static class Settings {
public static string AppName = "My Super Application";
public static string AppVersion = "0.9 beta";
}
XFighter wrote: what is partial class?
A partial class is a class that is partially defined in two different places, usually in two different files. This is regularly used when part of a class is auto generated, like a web page class.

Hi, is it possible to simulate mouse clicks in a windows form, though the form is hidden/invisible?
I want to write a kind of click bot for internet sites and because i can't directly access some elements from the site i want to simulate mouse clicks, but the form has to be hidden, so it doesn't disturb the user. is that possible?

Add this line to the top of your codefile:
using System.Runtime.InteropServices;
Then add these lines of code after the open brace in Form1 (or whatever your form is called):
private const UInt32 MOUSEEVENTF_LEFTDOWN = 0x0002;
private const UInt32 MOUSEEVENTF_LEFTUP = 0x0004;
<br />
[DllImport("user32.dll")]<br />
private static extern void mouse_event(<br />
UInt32 dwFlags,<br />
UInt32 dx,<br />
UInt32 dy,<br />
UInt32 dwData,<br />
IntPtr dwExtraInfo<br />
);
To simulate a left click, you would then use this code:
mouse_event(MOUSEEVENTF_LEFTDOWN, 0, 0, 0, new System.IntPtr());
mouse_event(MOUSEEVENTF_LEFTUP, 0, 0, 0, new System.IntPtr());
And that's it!

I recently read an article about how Passing data between forms.(http://www.codeproject.com/useritems/pass_data_between_forms.asp)
What it fails to explain(or I fail to understand) is how do I do it whilst I don't create objects of the form?
Here is the code below, abit long but simple...
I want data from the second form to be passed to the first form(then I could show it with labels)
[code]
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Text;
using System.Windows.Forms;
namespace AutoDownloader
{
public partial class Form1 : Form

Initiailize();
}
public void Initiailize()
{
this.Width=800;
this.Height=400;
this.StartPosition= FormStartPosition.CenterScreen;
Button AddShow = new Button();
AddShow.Click+=new EventHandler(AddShow_Click);
AddShow.Top = 300;
AddShow.Left = 20;
AddShow.Width = 100;
AddShow.Text = "Add New Show";
this.Controls.Add(AddShow);
}
public void AddShow_Click(object sender, System.EventArgs e)
{
AddShowForm subform=new AddShowForm();
subform.Show();
}
}
public class AddShowForm : Form
{
Label NewShow = new Label();
Label DownloadDate = new Label();
Label DownloadTime = new Label();
Label DownloadWebsite = new Label();

Button CloseForm = new Button();
public AddShowForm()
{
Start();
}

If it is an issue with an article, the best bet route should be to initiate a thread over the article's forum.

Very smart..
I had posted that msg in MSDN..
if you know abt this then reply

An 'Answer' was already marked out there. You can try figuring out any open handles on the files. But you may need to delve into P/Invoke for this.

I think u didn't read all the messages...
Thanks

You can prevent other users from accessing the file by specifying exclusive access when you open/create the file. Check the FileAccess versions of FileStream's constructor documentation for more info:
new FileStream(filePathName, FileMode.Open, FileAccess.Read, FileShare.None);
caveats:
- if you can't open the file with FileShare.None then a System.IOException will be thrown.
- ALWAYS code FileStream with the keyword "using" so that resources are freed if an exception is thrown.

I have a seperate project in my application with a great deal of code in that can take upto a minute to perform when performing a save on the main UI. The saving of this information is not required for the UI to continue working.
I have been investigating the BackgroundWorker class, I was hoping somebody would know of good code examples which would allow me to change the application so that when the main UI calls any methods on the seperate project these methods are all run on a seperate thread so that the main
UI does not wait for them to complete which results in a moderate amount of the hanging.
It seems I would have to use the BackgroundWorker on the method calls in the Main UI whereas I would like to simply have anything on this seperate project always run on a seperate thread.
I hope I have made sense as it is rather early.
Thank you for any help and sugestions you may have.

Hey everyone,
I might be doing it the wrong way, but I had to filter a dataset and view it in a datagrid to match a value in an outer control "treeview node in this case", anyhow, after filtering that, I had to fill the entire column which's supposed to be the foriegn key column with value of that outer control value "primary key", is there an easier/other way to do it?? other wise how do you manage to fill a datagrid control entire available column with copies of my primary key value??
Please help.
