How to set product's price?

[mage_ento]

Hi everyone, this is my first post

I can add new products like

$product
                ->setTypeId($type)
                ->setAttributeSetId(4)
                ->setSku($simpleproduct['code']))
                ;

$product

                ->setName($simpleproduct['name'])
                ->setDescription('Description')
                ;

etc.. When I save the product it shows in admin panel but I cannot set price, taxclass, and weight values like this way. After I set them manually from admin panel the product is shown in frontend. How can I set price, taxclass, and weight values like the codes above? Thank you.

Try it, below approach:

//Create product object
$newproduct = new Mage_Catalog_Model_Product();

//Set the stock data
$stock_data = array(
				'use_config_manage_stock' => 1,
				'original_inventory_qty' => 0,
				'qty' => $paramData['qty_avail'],
				'use_config_min_qty' => 1,
				'use_config_min_sale_qty' => 1,
				'use_config_max_sale_qty' => 1,
				'is_qty_decimal' => 0,
				'is_decimal_divided' => 0,
				'use_config_backorders' => 1,
				'use_config_notify_stock_qty' => 1,
				'use_config_enable_qty_increments' => 1,
				'use_config_qty_increments' => 1,
				'is_in_stock' => '1', //1 -> In Stock and 0-> Out Of Stock
				);

//Define data array like the below one
$dataProduct = array
		(
            'name' => '<Product_Title>',
            'sku' => '<Product_Sku>',
            'weight' => '', 
            'status' => '1',
            'tax_class_id' => '0' , //Default tax class id is Zero
            'url_key' => '', 
            'visibility' => '4', //Set the visibility 4
            'price' => '<Set_Product_Price>' ,
            'cost' => 'Total of <Ship Cost + Product Price>',
    		    'special_price' => '', //Optional
    		    'special_from_date' => '', //Optional
    		    'special_to_date' => '', //Optional
            'enable_googlecheckout' => 1,
            'msrp_enabled' => 2,
            'msrp_display_actual_price_type' => 4,
            'msrp' =>  htmlentities($paramData['msrp']),
            'thumbnail' => 'no_selection',
            'small_image' => 'no_selection',
            'image' => 'no_selection',
            'media_gallery' => array
		(
                    'images' => '',
                    'values' => array("thumbnail"=>null,"small_image"=>null,"image"=>null)
		),

            'description' => '<Product_Description>',
            'short_description' => '<Product_Short_Description>',
            'custom_design' => '',
            'custom_design_from' => '',
            'custom_design_to' => '',
            'custom_layout_update' => '',
		        'stock_data' => '<Pass Stock Data Array>', //See $stock_data array above
            'options_container' => 'container2',
            'page_layout' => '',
            'is_recurring' => 0,
            'recurring_profile' => '',
            'use_config_gift_message_available' => 1,
            'website_ids' => array
		(
                    '0' => 1

		),
           'store_ids' =>array(0,1,2,3) ,
           'category_ids' => '<YOUR_CATEGORIES_IDS>',
           'affect_product_custom_options' => 1,
		);

//Pass the above data to product object and call save method.
$newproduct->setData($dataProduct);
$newproduct->save();
