Change Hostname After Installing Oracle

2007-03-08T22:48:00.000-08:00

Hi Folks

It was from a while. I didn't write anything in my blogs because I have exam's and a lot of assignment to do.

Today I have to work on Oracle 9i but the service stop immediately after starting. I don't know why but I remembered that I changed the computer name so everything goes wrong after searching I found the answer

You have to change hostname to the new one in the following files.

· tnsnames.ora

· sqlnet.ora

· listener.ora

And delete all *.q file inside network/agent folder

Thanks to Oracle Forum

Adding new file to Oracle Database not change Control File size

2007-01-16T05:38:00.001-08:00

This is nice, when you create a database on thing that you have to do is setting the Max Clauses MaxDataFiles so this will determine the max number of data files in the database. Oracle use this number to create the Control file. So when you add another file the Control file will never change. Consider it like that, why I have to recreate the control file if one Max Clauses change? Because Oracle uses them to create the Control file.

Pass the page to server without validation

2007-01-16T05:32:00.001-08:00

This is a tricky, I think if I didn't study yesterday I will never know about this.

You can make a button pass the page to server without validation by using the Button ( Command ) property CausessValidation

This is an example

<%@ Page Language="C#"

Inherits="System.Web.UI.MobileControls.MobilePage" %>

<%@ Register TagPrefix="mobile"

Namespace="System.Web.UI.MobileControls"

Assembly="System.Web.Mobile" %>

protected void Command1_Click(object sender, EventArgs e)

{

if (Page.IsValid)

ActiveForm = Form3;

}

protected void Command2_Click(object sender, EventArgs e)

{

ActiveForm = Form3;

}

</script>

<body>

<mobile:form id="form1" runat="server">

<mobile:Label ID="Label2" Runat="server">Write a value</mobile:Label>

<mobile:TextBox ID="TextBox1" Runat="server">

</mobile:TextBox>

<mobile:RequiredFieldValidator ID="RequiredFieldValidator1"

Runat="server" ControlToValidate="TextBox1"

ErrorMessage="Text is required ">

</mobile:RequiredFieldValidator>

<mobile:Command ID="Command1"

Runat="server"

OnClick="Command1_Click"

Format="Link">Validate </mobile:Command>

<mobile:Command ID="Command2"

Runat="server"

CausesValidation="False"

OnClick="Command2_Click"

Format="Link"

SoftkeyLabel="No Validation !!!">No Validation</mobile:Command>

</mobile:form>

<mobile:Form ID="Form3" Runat="server">

<mobile:Label ID="Label3"

Runat="server"

ForeColor="Green"

StyleReference="title">You Passed</mobile:Label>

</mobile:Form>

</body>

</html>

Write simple ASP.Net Mobile Application

2006-12-14T02:10:00.000-08:00

Hi folks,

I hope everything good.

I would like to write about how to build an ASP.Net Mobile Application.

First of all, tools you need:

Microsoft Visual Studio 2005.
Pocket PC Emulator (Check on It while you install MVS).
ActiveSync 4.2

Now, after installation:

Open MVS.
File -> New Web Site-> Empty Web Site
Choose the location and choose your programming language and then OK.
Create new Mobile Web Page:
1. File -> New File -> Mobile Web Form
2. Name : FirstPage.aspx
3. Okay

Now you notice that there is a new Toolbox called “Mobile Web Forms”.
Click and Drag a Label control to the Form in the Design Mode.

Now write “” in Text property.
Save all.
And Right-Click on the page and select “View in Browser”.

You have to see the page in IE.

Now, how can I run and test the page on Pocket PC Emulator?

Actually, this is easy:

Tools -> Microsoft Device Emulator.

Note: if you don’t have it maybe you don’t have a combatable framework. But if you install MVS and install this tool with it you have to find it under X:Program FilesMicrosoft Device Emulator.

Click on the emulator you would like to run and choose Connect.
After a green arrow appear chose cradle.

Notice that now there are some “cable” picture this is mean that the device is connected but not with ActiveSync and if you try to test a page you will get error.

To solve this problem, you have to click on ActiveSync and choose Connection Settings.

Now in the connection Settings dialog make sure that you enable connection to DMA and the choose that this computer is connected to “The Internet”
Click on Connect.

You can see now there is a connection between ActiveSync and PPC Emulator.

Now you have to open PPC IE.
And write the page URL with the following format

http://ComputerName_OR_IP:PortNumber/TheRestOfUR

e.g. http://PC-Name:1096/Hi%20Mobile%202/FirstPage.aspx

And press Go

Happy programming.

Changing Firefox Portable Splash Screen

2006-12-10T23:25:00.000-08:00

Hi folks

I hope you doing fine.

Did you use Firefox? Did you love it? If you don’t use it give it a try. You will lose nothing. I used Firefox from version 1.5 and I want to tell you something it is better now with the new version 2.0. It’s awesome. I used also Firefox Portable. It’s the best I feel I’m at home when browsing net from university.

For those how like Firefox Protection Splash and would like to change Firefox Portable Splash you can need these tools:

NSIS Compiler.
FindProc plug-in.
NewAdvSplash plug-in.
Registry plug-in for Thunderbird Portable Splash.
After install those tools go to X:\ FirefoxPortable\Other\FirefoxPortableSource and paste the new *.jpg picture you like to use but rename it to FirefoxPortable.jpg.
Now right click on FirefoxPortable.nsis and chose “Compile NSIS Script” from the sup-menu.
Copy FirefoxPortable.exe to X:\ FirefoxPortable\
Have fun.

By the way NSIS plug-in goes in X:\Program Files\NSIS\Plugins after unzip.

See yea

Hi folks

I was checking an old mails and I saw one that's good :)

Father: I want you to marry a girl of my choice
Son : "I will choose my own bride!"
Father: "But the girl is Bill Gates's daughter."
Son : "Well, in that case...ok"
Next, father approaches Bill Gates.
Father: "I have a husband for your

daughter."
Bill Gates: "But my daughter is too young to marry!"
Father: "But this young man is a vice-president of the World Bank."
Bill Gates: "Ah, in that case...ok"

Finally Father goes to see the president of the World Bank.

Father: "I have a young man to be recommended as a vice-president."
President: "But I already have more vice- presidents than I need!"
Father: "But this young man is Bill Gates's son-in-law."
President: "Ah, in that case...ok"
