1. Is it a dll or exe?
You can try to import the dll into your asp.net project, if it fails, you can write a wrapper and try via a exe or try via a dll that can be imported.
-> exe, you can call exe's and pass arguments to them.
2. I'm not sure what job you're talking about, but I think so. You can also use a general (winforms/services) dll from C#(Vb.net) or use webservices.
3. I'm not sure what you mean by this.
4. I'm thinking in the line of a service. The page will reload, but always the cached version until a flag or something is checked. Then it will refresh.
Hope it helps a bit, good luck.

What Im wanting to do is to call a .dll from a .js
Say I've made some HelloWorld.dll with a
hello() system.Console.write("hello")
then in a .js want to call this function how do I do this??
function hello(){
var helloDll = new ActiveXObject("HelloWorld");
helloDll.hello();
}
Would this work if i put it in system32 folder or something..??

I have a table, with the field name GroupId and GroupName as primary key. In a asp file, I connect to the database and execute an insert query. What if the record which i`m going to insert is already in the database. How do I catch the error?

How do we know whether the procedure insert the record or not? How do we catch the error. By the way, I`m using SQL Server 2000.

I don`t know whether ASP script can do that. But thanks anyway.

You can raise the error in the Stored Procedure
Like Colin Stated
<br />
CREATE PROCEDURE InsertGroupIdAndName <br />
@GroupId int, <br />
@groupName varchar(128)<br />
AS <br />
IF NOT EXISTS(SELECT GroupId,GroupName FORM GroupTable WHERE GroupId = @GroupId AND GroupName=@groupName)<br />
BEGIN <br />
INSERT GroupTable(GroupId, GroupName) <br />
VALUES (@GroupId, GroupName) <br />
END<br />
ELSE<br />
BEGIN <br />
RAISERROR (Group Name:%d with groupID %d Already exists',<br />
16, 1, @groupName , @GroupId)<br />
END<br />
GO
16,1 = severity , state
lookup proper syntax for RAISEERROR
Then Catch the error in the code. You do catch you errors right?
If using vbscript in the asp page....
<br />
On error resume next<br />
<br />
Database insert stuff...<br />
<br />
If err.number <> 0 then<br />
do something with err.number & err.description<br />
End IF

I read Nick Pirocanac's CoolButton composite control article and downloaded the code and have it running on my machine.
I created a simple composite control from scratch but the delegate is never called and the event never fires. I would appreciate another pair of eyes to point out what I am missing. Here is my code:
namespace TestCustUC
{
[ToolboxData("<{0}:WebCustomControl1 runat=server>")]
public class WebCustomControl1 : System.Web.UI.WebControls.WebControl
{
private Button butOK;
public event EventHandler Click;
protected override void CreateChildControls()
{
butOK = new Button();
butOK.Text = "OK";
butOK.Width = Unit.Pixel(50);
Controls.Add(butOK);
// Add handler for the OK button click postback event.
butOK.Click += new EventHandler(this.OnButOK_Click);
}
protected virtual void OnButOK_Click(object sender, EventArgs e)
{
if (Click != null)
{
Click(this, e);
}
}
}
}
Thanks for taking a look!

I had to study the examples in the SDK QuickStart (plus others I found online) quite a bit before I got my own custom control working just the way I wanted. I changed your code slightly in headers and declaration, and the event is now triggered; hope this at least helps get you started. Check out esp. info on implementing the INamingContainer interface and EnsureChildControls.
Regards,
-lp
using System;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
namespace TestCustUC
{
//[ToolboxData("<{0}:WebCustomControl1 runat=server>")]
public class WebCustomControl1 : Control, INamingContainer
{
private Button butOK;
public event EventHandler Click;
protected override void CreateChildControls()
{
butOK = new Button();
butOK.Text = "OK";
butOK.Width = Unit.Pixel(50);
Controls.Add(butOK);
// Add handler for the OK button click postback event.
butOK.Click += new EventHandler(this.OnButOK_Click);
}
protected /*virtual*/ void OnButOK_Click(object sender, EventArgs e)
{
if (Click != null)
{
Click(this, e);
}
}
}
}

epatton -- Thanks for taking the time to dig into my code and suggest changes and resources for more information!
I played with the code as well and got it to work following a different avenue. It appears that if you attribute the control class for design time support ([DefaultProperty("Text"),ToolboxData...), then you should follow through and implement, for example, the 'Text' property, using the call to 'EnsureChildControls'.
Sounds OK, huh? But the project still didn't run correctly!
This will sound like a bunch of hocus pocus, but the next thing i did was to re-arrange the Page and Register directives on the .aspx page that used the control, F5 and then everything ran perfectly!
I believe this forced VS to rebuild its in memory representation of the project, rewiring the project correctly and allowing it to run.
Anyway, that's my theory....
Thanks again for your help.

Hi frinds,

thanks

when you open a new window using window.open(), you end up naming the window in the second argument.
window.open("bob.html", "bobWin", "width=500, height=500") for example creates a new window called bobWin. if you use that instead of "window", you should be able to point to anything there.

Hi all, i am involved in writing an application at the moment that will require IIS to be installed to run. Is there a way that i can check to see if IIS has already been installed when i install my application? And if it has not already been installed i need to install it, although i think i can manage that bit 
Cheers

Hi,
does anyone know how macromedia does the silent install of the flash player? do i need wise to automatically install some components? or can i use msi...if so how do i do it?
thanks

i know that other tools have a "/silent" option, where you can execute them with the silent commandline flag. i would presume that msi would have the same or similar...

Even though it is not defined on this page :p, the .msi install option you want is "/q". I'm sure there is a similar list of .msi install option flags somewhere on Microsoft's site...

the short answer is: you can't.
the long answer is: you can get the user to download the file.

Thanks for the reply.
Actually I am searching for a solution other than download or saveAs method.
That means the work should be done without user's knowledge.
Thanks

like i said before: you can't. the webserver doesn't even know who or what the client machine is. the only way you can transfer files to the client machine is via active download. the client *has* to request the file, the server cannot just send it.

Imagine surfing to a website, and without your knowledge they could place a file on your hard-drive (*). I think you can see why this is not permitted.
(*) There have been security flaws in IE that allow exactly this, but they are usually shut by the next security patch.
