use Path.GEtTempFile to get a unique filename. The only way I know to know if a file is in use, is to use a try/catch block when trying to access it.
Why are you writing text files on your server ? If you have many users, perhaps a database is a better place for it ?

There is a node A and from this I am trying to access
node B (the web server) with url:
http://172.16.216.187/test/Default.aspx
Now what code shall I write in the Default.aspx.cs at Page_Load (at node B, the web server) such that any program (say notepad.exe) runs on node A.
I tried :
System.Diagnostics.Process.Start("notepad.exe");
But this does not help..
Any solution??
Thanx in advance..

I think a window will pop do you want to save or run this exe
As far as my understanding goes, this would prompt me to run/save the exe from the web server..
What I want to do is run an application present in the Clients computer..
Any application will do, but it should run the application from clients system and not save or run the application from the web server..
As I am new to ASP.NET, I read that ASP is a server side programming..
So can we use ASP.NET to run applications on the Client side??
Do I have to inject scripts the server code to do all this??

You cannot run programs on the client using asp.net. You'll need to code some kind of activeX control or applet to do this. But you should consider what you are doing - a lot of people would not be happy to have their web browser control their pc in this fashion.

Another person who has no idea what ASP.NET is or does, and is paid to write ASP.NET code. I weep....

Of course not. your C# code runs on the server. You want to run an exe on the client. I'd suggest you're going to have a hell of a time doing that.

Can someone tell how can I pass a C# variable value as a parameter in a javascript function please?
because i am still not so confident in scripting
thanks

Basically, you need to use registerclientscriptblock to create a javascript variable which has the C# value as it's value. As in:
int c = "string";
RegisterClientScriptBlock("cStrig", "var str = '" + c + "'");
Of course you need to emit script tags as well, but that's the overall idea. You need to create a javascript variable that contains the value you want to pass through. The most likely reason to do this is to get the client side id of a control on the client side, where you use code like:
RegisterClientScriptBlock("textbox1", "var textbox1Id = '" + textbox1.ClientID + "'");

If I could see your code, I'd try to comment on it.

It could be that you need to set the focus on the delete button although like the post above i think you will need to show your code for us to help you further

Might be you are populating any data sorce which is not again bind again
you need to bind that data again check it or show your code

The above is the aspx page. And in code behind page
protected void MyDataList_ItemCommand(object source, DataListCommandEventArgs e)
{
string id = e.CommandName.ToString ();
if (e.CommandName == "Delete")
{
DBLibrary ob = new DBLibrary();
ob.path1 = Server.MapPath("Database/BlogSiteData.mdb");
string uid = Session["user"].ToString();
string photoid = MyDataList.DataKeys[(int)(e.Item.ItemIndex)].ToString();
System.IO.File.Delete(Server.MapPath("Albums/" + uid + "/" + photoid + ".jpg"));
string sqldel = "Delete from Albums where Userid='"+uid+"' and Photoid=" + int.Parse(photoid) + " ";
ob.ExecuteNonQuery(sqldel);
BuildGrid();
}
}

try putting a simple bit of code in the command for delete so you can check that is working and then you can go through the exisiting code and see which part of that is causing the problem
