Here's what happened:
I created an ASP.NET eCommerce site half year ago for a school assignment, it was deployed locally on my hard drive, and everything worked.
However, I am planning to create a real eCommerce site now, so I had applied for a webhosting server that supports ASP.NET, and uploaded the assignment I did earlier and see how it would go.
To my surprise  , all I get is the message:
<br />
Runtime Error <br />
Description: An application error occurred on the server. The current custom error settings for this application prevent the details of the application error from being viewed remotely (for security reasons). It could, however, be viewed by browsers running on the local server machine. <br />
<br />
Details: To enable the details of this specific error message to be viewable on remote machines, please create a <customErrors> tag within a "web.config" configuration file located in the root directory of the current web application. This <customErrors> tag should then have its "mode" attribute set to "Off".<br />
<br />
<br />
<!-- Web.Config Configuration File --><br />
<br />
configuration<br />
system.web<br />
customErrors mode="Off"/<br />
/system.web<br />
/configuration<br />
<br />
<br />
Notes: The current error page you are seeing can be replaced by a custom error page by modifying the "defaultRedirect" attribute of the application's <customErrors> configuration tag to point to a custom error page URL.<br />
<br />
<br />
<!-- Web.Config Configuration File --><br />
<br />
configuration<br />
system.web<br />
customErrors mode="RemoteOnly" defaultRedirect="mycustompage.htm"/<br />
/system.web<br />
/configuration<br />
<br />
Is there anything else I need to do when deploying an ASP.NET site to a real webhosting server?
And another question, I was planning to store database information in an access database. Here's the question I'm wondering:
I suppose I should password protect the directory where the access databases (*.mdb) are placed. I assume I have to insert the login id/password when retreiving/writing the information in the database. But where do I insert them? And if I insert them in the codes won't others will be able to see the login id/password by viewing the source codes?
Or am I completely mistaken? 
Any advice would be greatly appreciated!!!

Brotha, you're first step ought to be following the instructions on that error message up there to find out what is causing this bug. If you follow the instructions in this error message, it will display a much more specific error message indicating exactly what caused this failure. There should be very little different about a hosting provider vs. your local machine, but you'll never know until you see the real error message.
And as far as your MSAccess question, you set the connection properties in the web.config file. No one can download the web.config file, ASP.NET/IIS knows automatically to never serve up that file. If you need to find out how to setup the DNS within your web.config, you might wanna check out the this faq.

Hi,
I have a textbox.I want to check if data entered in it contains any characters other than digits from 0 to 9.How can I do that. Are there any built-in functions to do this.I don't want to restrict the entry of characters. I want to know whether the data is numeric or alphanumeric.

You could use int.TryParse(..) which will tell you if a string can be parsed into a number.

Hi, I have a COM object written in C++ that contains a method that must modify a variable passed to it via ASP. In my C++ come method, I delcare the variable as type VARIANT*. This ideas works ok in C# and VB but fails in ASP. Is there a special way that you have to set up a variable in ASP to pass it to a COM object method for modification. In VB you must pass it by ref, but I am not sure what happens in ASP. The ASP error suggests that there is a type mismatch on the variable I am passing to my COM Object method. This is a bit confusing.. Can anyone help me sort this out?
I really appreciate it.
Thanks

oceanexplorer,
Sounds like you are trying to host a web page inside of an existing webpage. It does not take ASP.NET to do this... Just an IFRAME tag:

This code sometimes runs fine and sometimes gives me following error.
An unhandled exception of type 'System.ExecutionEngineException' occured in translationservice.dll.
Server Application Unavailable
The web application you are attempting to access on this web server is currently unavailable. Please hit the "Refresh" button in your web browser to retry your request.
Administrator Note: An error message detailing the cause of this specific request failure can be found in the application event log of the web server. Please review this log entry to discover what caused this error to occur.
After this error comes up CPU usage reaches to 100%.
I do not understand what is the problem with my code. I will appreciate if someone of you guys could help me about it.

If you want it to work on each character typed, you must do it through DHTML and not ASP.NET. ASP.NET would require you resubmit the form (aka Postback) each time the user types something, which would be insanely slow for the poor user and would kill the resources of your server.
Try using the onKeyPress event found in the "input type=text" object. Within that event, update the label by setting it's innerHTML property.

hey sorry but i want to tell you , i heard abt somrthing called ajax it enables that stuff it allows you for each type of a caracter the label can receive it & also i heard that you can add some javascript i heard a lot of things but i don't know how to use them i searched a lot but you don't find somebody who can tell you the right thing to do
what is this propriety you told me innerHTML ?
