$objDB = mysql_select_db("mydatabase");
// Search By Name or Email
$strSQL = "SELECT * FROM proposals WHERE (pro_name LIKE '%".$_GET["txtKeyword"]."%' or pro_company LIKE '%".$_GET["txtKeyword"]."%')";
$objQuery = mysql_query($strSQL) or die ("Error Query [".$strSQL."]");
$Num_Rows = mysql_num_rows($objQuery);

if (!isset($_GET['Page']))

this is the error :

Warning: mysql_fetch_array() expects parameter 1 to be resource, boolean given in C:\xampp\htdocs\CDMS\proposal2.php on line 79

there is also :

br /><b>Notice</b>: Undefined index: txtKeyword in <b>C:\xampp\htdocs\CDMS\proposal2.php</b> on line <b>10</b><br />

in the textbox..

From what i see, you have the connection, but you need to include the variable into the mysql_select_db

$objDB = mysql_select_db("mydatabase", $objConnect);

Second, make sure to difine txtKeyword. just add $txtKeyword = $_GET['textKeyword']. I would just make one if statement.

if (!isset($_GET['txtKeyword'])) {
    if($_GET["txtKeyword"] != "") {
        $txtKeyword = "%"
    }
    // rest of connection

Also, make sure you know the difference from $_GET and $_POST. To really test it, just have the connection by its self just to make sure everything is ok. I hope this helped.

you should check if $_GET["txtKeyword"] is set.
see you code in line 7 if($_GET["txtKeyword"] != "")

error will occur if you will try to read or put this index to a condition becuase this index might not be found..

as your code says there will be an instance that if($_GET["txtKeyword"] != "") will be empty so.. check first if it is set

if (!isset($_GET['txtKeyword']))
{
//Instruction if $_POST['value']doesnt exist
$_GET['txtKeyword']="%";
}
if($_GET["txtKeyword"] != "")
{ set

from your line of codes

you can do this instead: put $_GET["txtKeyword"] to a variable then check if its empty like this.

    $txtKeyword = (!isset($_GET['txtKeyword']))?"%":"";

    if($txtKeyword!= "")
    {  #..... preceeding code

It usually means that your query is wrong. Echo the query to the screen and copy/paste it into the sql window of phpmyadmin. See what it gives you.

yah diafol is correct
or see this line from your code $objQuery = mysql_query($strSQL); insert die(mysql_error())
so it looks like this $objQuery = mysql_query($strSQL) or die(mysql_error());

The code on lines 16 to 20 is a bit suspicious:

if (!isset($_GET['Page']))
{
    //Instruction if $_POST['value']doesnt exist
    $_GET['Page']="%";
}

$_GET['Page'] is supposed to be an integer, isn't it? In some circumstances the $Page variable could be assigned a value of % and the query would fail since $Page_Start and $Per_Page wont get calculated correctly:

$strSQL .=" order by pro_id ASC LIMIT $Page_Start , $Per_Page";
