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. :)

Happy New Year 2008 At Genting, Malaysia

Happy New Year 2008 to all my readers!

Well, I am celebrating New Year 2008 at Genting (now 1:52am 01/01/2008)
I am writing this blog at Starbuck beside Genting Resort.

Last year, just now, 2007 eve, was entertaining Jacky Wu & friends at Star Of Arena, Genting.
Out of my expectation, not too excited because Jacky ( my idol ) not creating much more jokes (as usual).

Download Gmail To Outlook

I tried to add Gmail POP manually ( without referring any information ) to outlook and create several issues such as duplicated outlook email and loading all my Gmail ( about 3Gb )... My goodness! Because I checked "Leave a copy of message to mail server"

So here we have a better way to do it!

Steps:
1. Login you Gmail > Settings ( Right Top )


2. You can refer the settings above, depend on your needs.
a. Forwarding:
Disable forwarding because I am not going to forward my gmail to other account.

b. POP Download:
Probably you will need the second check box if your Gmail message is large!
Second option will only retrieve the new Gmail from the time you set it.

c. Choose 'Archive Gmail copy' . This option will help you leave a copy into your 'ALL Mail' in your Gmail. Thus, NO NEED to check the outlook 'Leave a message on server' option.

You should read the configuration part to get further information.

For fast settings, refer here:
On your outlook

Account Type: POP3
Incoming mail server: pop.gmail.com
Outgoing mail server: smtp.gmail.com
User Name: your-gmail-account ( I prefer full gmail rather than ID )
Password: your-gmail-password
Check the 'Require logon using Secure Password Authentication (SPA)


Outgoing SMTP



Delivry settings ( no need to check it )

You may test your email by sending it to your self :)

Thank Gmail for POP3 service !!
