I would like to automate downloading historical data.
I do not want to be asked userid and password when I download the data.
I would like to download data after close every day.

Is there a way to automate this?

There is no way to directly access the servers for data. You should only have to log in once to IQFeed, then make your requests for the historical data. You can automate the login process within your code though.

How do I automate the login process with in my code?
Does it involve com programming?
Can you give me an example?

It should be no problem if you use automatic log in option.

I have been doing it for a long time.

What language are you programming in? In order to start IQConnect, you need to be able to call the RegisterClientApp and RemoveClientApp functions in IQ32.dll. If you are using C++, linking the library IQ32.lib and including the IQ32.h header in your project gives you access to the dll. If you are using a language which doesn't utilize .lib files, you need to import the calls into your program. Use the IQ32.h file to see the usage of these functions.
For example, in C#:

[DllImport("IQ32.dll")]
public static extern int RegisterClientApp(IntPtr hClient, string szProductName, 
			string szProductKey, string szProductVersion); 

You need to make sure your .exe is in the same directory as IQConnect.exe so the dll will load properly or add this directory to your path. For the ProductName, be sure to use the name you registered when you set up your account.

After registering your app, all data can be retrieved via TCP ports, the ActiveX control, or the COM interface.

When the IQConnect asks for your login information, you can select "Automatically Connect". This can also be set programatically using the SetAutoLogin and ClearAutoLogin functions.
