Remove Blogger navigation bar

2011-01-28T10:26:00.000-08:00

I know I don't usually write my blog. But today I changed my template because the old one really looks ugly. I didn't know why I picked that at the first place few years back.

After changing my template, I found out that the navigation bar from blogger is back!!! I forgot what I did before, so I ended up checking the CSS using Firefox + Firebug(best combination ever in my opinion). A picture is worth 1000 words. The highlighted is what you need to add.

Settings / Design / Edit HTML

Add the CSS code at the top of the template you chose.

#navbar-iframe { display: none !important;}

Save the template and you should see the magic :)))

ASP.NET IIS Firefox authentication required problem

2009-07-25T16:03:00.000-07:00

Today, I had problem with running my asp.net project while using Firefox. It asked me to enter username and password to see the page. However, I tried all the passwords and none of them worked. This problem never occurred before, so I googled and finally found the solution.

Enter about:config at firefox address bar. (You will see warning message indicating that these are advanced settings that may affect the browser security and stability)
Click "I'll be care, I promise" button
Search network.automatic-ntlm-auth.trusted-uris at filter. (Only one entry will be appear)
Double click the entry and type localhost.
Save it and reload your web page then DONE!

Accessing Posted Data in ASP.NET

2009-07-24T19:05:00.000-07:00

There are two ways to access data using Page.PreviousPage in asp.net

1. Using FindControl function


string username = ((TextBox)PreviousPage.FindControl("tbxUsername")).Text;

2. Using Strongly Typed Data
I personally like this one because I don't care about what the control name is. Also, no typo mistakes will be made.
Here is how to make a strongly typed data


public string UserName
{
 get{return tbxUsername.Text;}
}

Also we have to set the code below at the page that receives the posted data.


<%@ PreviousPageType VirtualPath="~/pageName.aspx" %>

Last step, you have to rebuild in order for page to see the property in receiver page.

ASP.NET CustomValidator with Javascript

2009-07-22T15:13:00.000-07:00

To use CustomValidator with client side javascript validation, we need to implement a javascript with two parameters.


function YourFunctionName(source, arguments)

Set property ClientValidationFunction to the name of your javascript at CustomValidator control.

arguments.Value is the data that we will be validated.

arguments.IsValid indicates validation success or failure.

If the validation is passed, we set arguments.IsValid = true. False otherwise.

Using Output Caching to Enhance Web Site Performance

2009-07-11T16:50:00.000-07:00

There are 2types of caching for ASP.NET

1. Configuring Page-Level Caching
copy the code below to aspx html source page


<%@ OutputCache Duration="15" VaryByParam="none" %>

Duration means the duration of the cache. In this case, it will cache for 15 seconds.

the name "AppCache1" will be used to the pages that you want to have cache. You can have different kinds of cache options by just adding another profiles like the code below

what we have to do in each of our page is add the code below


<%@ OutputCache CacheProfile="AppCache1" VaryByParam="none" %>

Note: the name of the CacheProfile is the name you set in outputCacheProfiles in web.config.

The attribute VaryByParam is used for caching parameters (eg. querystring) of a page.
example:


<%@ OutputCache Location="Server" Duration="60" VaryByParam="Color" %>

Here we have a param called "Color". (http://mysite/mypage.aspx?Color=red)
When user goes to the page wtih Color=red, it caches the page with param Color=red for specific duration according to our setting.

If we specify the VaryByParam parameter, any new value will be cached. For cached value, it loads data from cache.

Here's the detail explanation of VaryByParam from Microsoft MSDN
==================================
The @ OutputCache directive requires you to set the VaryByParam attribute, which until you now you have set to "none". The VaryByParam attribute enables you to configure caching so that ASP.NET stores different versions of a page depending on parameters such as query strings, form post values, request headers, and so on.

For example, you can use cache parameters in a page that displays weather conditions for select cities, where the weather data is refreshed only every three hours. In this scenario, you want to cache a separate version of the page for each city. You can do so by setting the cache parameter to vary by a query string parameter.
==================================

Silverlight 3 Element to Element Binding

2009-07-10T15:42:00.000-07:00

We don't have to create tons of events for updating values, texts to different controls.

The code below does it all. No additional coding inside cs file.
{Binding Value, Mode=OneWay, ElementName="MyControlxName"}

It's like the old binding style except that we have ElementName to tell the compiler that we want to bind the property to the element MyControlxName's Value property.

ASP.NET Dynamic Compilation

2009-07-09T11:15:00.000-07:00

Unlike ASP, ASP.NET doesn't have to compile each and every time it is requested. An ASP.NET page is compiled only once when an application is modified. If it is not modified, the Framework will look for the directory

\WINDOWS\Microsoft.NET\Framework\v2.0.50727\Temporary ASP.NET Files

to load the compiled dll.

However, if a site contains thousands of pages. Having Framework to precompile everything and store in the temp folder isn't a good choice. Here the way to chose if you want the compiler to precompile or not.
Adding CompilationMode attribute inside the <%@ Page Language="C#" %> tag at html source code view.
The attribute has Always, Auto, and Never. I believe the default is Auto :)

InvalidOperationException: HtmlPage_NotEnabled

2009-06-09T16:01:00.000-07:00

Add this in Page_Loaded
==========================
if (DesignerProperties.GetIsInDesignMode(this))
return;

To avoid this problem, be sure to check if you use HtmlPage class in Page_Loaded.

If inside Page_Loaded you call another functions, make sure they do not call HtmlPage class. Otherwise, use the if statement I provided above.

Spring + Hibernate

2008-03-08T04:02:00.000-08:00

There are some packages that will be missing if you just copy sample code from the book "Manning.Spring.in.Action.2nd.Edition" when working with hibernate template

NoClassDefFoundError: javax/transaction/TransactionManager
you need jta.jar from springframework folder "lib/j2ee"

NoClassDefFoundError:org.hibernate.cfg.AnnotationConfiguration

value hibernate.dialect property is from http://www.hibernate.org/hib_docs/v3/api/org/hibernate/dialect/package-summary.html
depends on the database you are using, find the proper one. I am using PostgreSQL, so the value will be "org.hibernate.dialect.PostgreSQLDialect"

Basically to run hibernate in spring framework
the jars listed below are the necessary ones

my spring framework folder is C:\spring-framework-2.5.1-with-dependencies\
I will use springfolder for now

Setting PostgreSQL to SSL Enabled

2008-03-08T00:42:00.000-08:00

Follow the steps below to set your PostgreSQL database to SSL enabled.

At the very begining, we have to determine the operating system that we are using, I don't know how to do in Linux or Unix because the OS I'm using is Windows.

1. Download Win32 OpenSSL program from Shining Light Productions

2. Install the exe file by clicking next, next ... next, done ( very basic way to install a program)

3. Open command prompt (cmd.exe) and go to your Win32 OpenSSL installed folder (in default, C:\OpenSSL\bin)

4. type "openssl req -new -text -out server.req" and press enter

Loading 'screen' into random state - done
Generating a 1024 bit RSA private key
.................................................................................++++++.............................++++++
writing new private key to 'privkey.pem'
Enter PEM pass phrase: "ENTER PASSWORD" (example, "changeit")
Verifying - Enter PEM pass phrase:"REENTER PASSWORD" (example, "changeit")
-----You are about to be asked to enter information that will be incorporated
into your certificate request.
What you are about to enter is what is called a Distinguished Name or a DN.
There are quite a few fields but you can leave some blank
For some fields there will be a default value,
If you enter '.', the field will be left blank.
-----
Country Name (2 letter code) [AU]: Just Press Enter (leave it empty)
State or Province Name (full name) [Some-State]:(leave it empty)
Locality Name (eg, city) []:(leave it empty)
Organization Name (eg, company) [Internet Widgits Pty Ltd]:(leave it empty)
Organizational Unit Name (eg, section) []:(leave it empty)
Common Name (eg, YOUR name) []: your host name (lanf-blog.blogspot.com)
Email Address []:Just Press Enter (leave it empty)

Please enter the following 'extra' attributes
to be sent with your certificate request
A challenge password []:(leave it empty)
An optional company name []:(leave it empty)

5. now that if you go back to openSSL instaled folder c:\openSSL\bin\ you will see "privkey.pem" and "server.req"

6. go back to command prompt and enter "openssl rsa -in privkey.pem -out server.key"
Enter pass phrase for privkey.pem: enter the password you entered from previous step (example, "changeit")
writing RSA key

7. now that you'll see "server.key" in your bin folder

8. Delete privkey.pem. (We delete this is because it's not needed anymore, if we leave it there, we then have to type our password everytime we restart our computer <-- not tested, I just deleted) 9. go back to command prompt and enter "openssl req -x509 -in server.req -text -key server.key -out server.crt" to create server.crt certificate

10. copy server.crt and server.key to your PostgreSQL data folder (int default, "C:\Program Files\PostgreSQL\8.2\data"

11. at the same folder mentioned from previous step, search for "#ssl" and change "#ssl = off" to "ssl = on" (delete "#" and change "off" to "on")

12. stop and start PostgreSQL server

13. done

to test if it's properly modified, we then open pgAdmin III (exists when installed PostgreSQL server in windows environment) and check the database property "Encryption" to see if the value is "SSL encrypted".

Linux 的簡單指令

2007-10-25T23:44:00.000-07:00

本身從來沒碰過linux,但也是因為學校所以我就小學了一下linux的指令
雖然用fedora的話就不太需要指令了還是可以用Ctrl + C(複製) 跟 Ctrl + V (貼上)

但是呢另一個課是需要用 putty 來連我們老師的linux server
話說~putty這程式的名字唸起來還真是可愛

回正題~連老師的linux的server的時後就是command line mode了所以我們才需要學一些指令

mv a b (將a檔案改名成b, 目錄也可以)
rm a (將a檔案殺掉)
rm a -r (將a這個資料夾刪掉,包括a裡面的檔案) (其實也可以直接用rm a就好但是如果資料夾有東西的話就沒辦法刪了。而-r 這個parameter就是也刪除裡面的檔案的意思)

mkdir b (建立一個資料夾叫b)

在linux裡面 . 是目前的資料夾位置

cp 是copy 指令

強制刪除印表機的任務

2007-10-22T22:43:00.000-07:00

相信有印表機的人可能有這樣子的經驗
我想要列印但是印表機的狀態上有一個文件 or 任務卡在那邊害我沒辦法列印我想要印的東西

以下也是我在網路上找到的方法

rem ------- 從此複製 -------
@echo off
Net Stop spooler
Del /f /q %systemroot%\system32\spool\printers\
Net Start Spooler
rem ------- 複製結束 ------

將上面有顏色的文字複製下來並貼在一個文件檔裡面存好檔之後再把檔名改成 .bat
之後再執行這個bat檔就好了
以上的code就是先停止印表機的服務然後再刪掉
%systemroot%\system32\spool\printers\ 裡面的任務
最後再開啟印表機的服務

我本人試過了真的可以用用這方法我們就不需要重開機搞些有的沒的了
