Xampp With Custom Port Setup

Usually IIS will occupied port 80 for those ASP.NET developer or some other reason, other application had grab over the port e.g: Skype.

In this case, we might need to use different port for Apache web server.
Recommend to port 88, 8088, 8888 and so on ( 8 looks and feel goods for me )

What changes need to be done?

1. Get your httpd.conf, usually located inside apache installation and inner conf folder.

Example of my httpd.conf location and I am planning to use 8088 as my custom port:
C:\xampplite\apache\conf\httpd.conf

2. Change the default Listen 80 to your custom port
#
# Listen: Allows you to bind Apache to specific IP addresses and/or
# ports, instead of the default. See also the
# directive.
#
# Change this to Listen on specific IP addresses as shown below to
# prevent Apache from glomming onto all bound IP addresses (0.0.0.0)
#
#Listen 12.34.56.78:80
Listen 8088

3. Change Server Name with the correct port too.
#
# ServerName gives the name and port that the server uses to identify itself.
# This can often be determined automatically, but we recommend you specify
# it explicitly to prevent problems during startup.
#
# If your host doesn't have a registered DNS name, enter its IP address here.
#
ServerName localhost:8088

4. Restart Apache server and you can browser with http://localhost:8088/


Incase you have problem to check your port, you can always run this application bundle with XAMPP named: xampp-portcheck.exe

It will shown you which port are occupied by which programs.


In case your 443 port being use by IIS and you are not using SSL on IIS.
You can try to stop your IIS and start Apache before IIS.
Hope this help.

NoMao - The Place To Bee




http://www.nomao.com

NoMao, a new name of online map application.

It applied Google Maps API ( I think so ) and really friendly to use.

It allows us to 'bee' on a spot on the earth and share your locations to your friend or placed the widget on your blog.

I would like to say the GUI is really attracting me with all those fancy AJAX technology!!

Let's try somethings!


Figure 1: Click sign up and search for a spot or to add a new spot.


Figure 2: Cute GUI to guide you!


Figure 3: You got your spot added and you can get the widget code and post on your blog!

My Two Cents
I use to play with Google Earth and Google Maps, so far so good, hope there are more information added to our local Google Maps.(currently don't have traffic info and detailed descriptions)

You can take this opportunity to post your business spot or to memories some special places that you want to mark it down. Probably your first dating place? Well, enjoy the technology!

Xampp With Multiple Sub Domain Setup

Let's say my IIS occupied port 80, and my XAMPP or XAMPPLITE on port 8088.
Assume that htdoc directory configure on C:/xampplite/htdocs/

Note:
email in the vhost has to be valid settings.
we might not need the error log or custom log in the vhost settings.

REPLACE all ( to < and ) to > Due To Blogger not allow those tags!

1.C:\WINDOWS\system32\drivers\etc\hosts
127.0.0.1 mysubdomain2.test.com
127.0.0.1 mysubdomain3.test.com

This is for development settings, in actual, you can set this on your domain manager tools.


2. extra\httpd-vhosts.conf

#yeeling added
NameVirtualHost *:8088

#yeeling added

Component cannot be created and AspCompact need to be TRUE

Usually in a vb6 to ASP.NET migration process, you will get this error.
Error: The component 'myCOM.COMClass' cannot be created. Apartment threaded components can only be created on pages with an <%@ Page aspcompat=true %> page directive.System.Web

The error above noted that we need to add page directive aspcompat = true because you are using COM interop with ASP.NET pages.

Just simply add the page directive "aspcompat=true" and it solved! :)

Exception : thread was being aborted / mscorlib

I got this message while debugging in asp.net 2.0 at this
Response.redirect("myABCfile.aspx")


I was thinking what's wrong with this line and you will get this exception if you throw the exception out to the display only.

Surfing around and I got the answer.
We have to understand how response.write or server.transfer work!

In ASP.NET, response.write and server.transfer will end the threading with response.end.
Thus, if we have a TRY...CATCH...END TRY within it, the TRY Thread will be aborted and ended suddenly and the exception will be caught.

We should make the response.redirect before or outside the catch at this point.

Usually, we will have a checking for session lost at the beginning of the page.

If String.IsNullOrEmpty(Session("user_id")) Then
Response.redirect("myLoginPage.aspx")
End if


This simple validation portion might not need to be inside Try Catch loop and you will be safe!

In addition, sometimes programming like to declare variable inside Try Catch loop too, and it is NOT necessary to do so.

A simple statement likes
Dim myString as string
is NOT necessary to be in Try Catch loop. :)
