Hi again,
Several points that can help more:
1. If you are working with Dot.Net, then I highly recommend read the first link that you got! This is nice and simple coding. Another option is this link which is even better in my opinion:
http://www.dotnetgallery.com/kb/resource21-How-to-store-and-retrieve-images-from-SQL-server-database-using-aspnet.aspx
2. As i mention above both link use the column's type image. There are several other option of working with Files. In most of my applications architecture I find that it is better to use a column which let us use any type of file and not an image column.
In choosing the right column's type for your needs basically your fist question should be if if you want to store your data inside relational database environment or outside relational environment. It is a good idea to look for blogs on this issue. Next
if you chose to store your data inside then you need to chose the right column type according to your server version. I highly recommend to look for blogs on the differences between those column's types: IMAGE, 
Check those links:

  • How do I create a duplicate image inside the same page? Then how do I change the color of that image

    how do I create a duplicate image inside the same page? Then how do I change the color of that image from black to red?

    Hello there!
    Here is one way to create a duplicate image and colorize it. As you can see below, I have one image right now, that I want to duplicate.
    My layers panel looks like below.
    To duplicate your image, click the downward arrow on the right side of your Layer Panel.
    Select Duplicate Layer. This will duplicate the layer that the image is on.
    Select "OK" to approve the duplication.
    As you can now see in the Layers panel, the image is duplicated. The new layer is now at the top of the Layer panel.
    Now to colorize your image, go to Window > Adjustments.
    The Adjustments panel will now be opened. Select the Hue and Saturation icon as seen circled in red.
    The Hue and Saturation propertied panel will be opened. I selected "Colorize", and adjusted the hue and saturation bar to achieve the level red in my photo.
    As you can see below, the image is now red.
    Now i want to make sure only ONE of my image layers is red. I moved the Hue and Saturation layer to only be on top of the bottom layer. The image on the top layer now will not be affected by the red.
    Select the move tool, so I can now move the image layers so we can see both of them.
    With each image layer selected, you can take the move tool and move the images. I moved mine on top of eachother and you can see my red layer (bottom) and the non red layer (top).
    I hope that helps. i have also included helpful links.
    Please post back with any questions,
    Janelle

  • TS3212 i have a toshiba thrive and want to put itunes on it, is that possible and how?

    how do i get itunes on my toshiba thrive?

    I gather that the Toshiba Thrive is an Android device. There is no version of iTunes for the Android operating system and therefore you cannot install iTunes onto the Thrive.
    Note: you have posted in the iTunes For Windows discussions. There is a discussions forum for iTunes for Mac. Did you not notice that there isn't one for Android?

  • I installed Mavericks on my macbook pro and now I want to go back to Lion, is this possible and how?

    I'm not satisfied with OS X Mavericks and I'd like to go back to OS X Lion! How do I do this as easy as possible?

    Erase your hard drive and install your Lion system backup. If you don't have a Lion backup, the you can do an Internet Recovery:
    Install Mavericks, Lion/Mountain Lion Using Internet Recovery
    Be sure you backup your files to an external drive or second internal drive because the following procedure will remove everything from the hard drive.
    Boot to the Internet Recovery HD:
    Restart the computer and after the chime press and hold down the COMMAND-OPTION- R keys until a globe appears on the screen. Wait patiently - 15-20 minutes - until the Recovery main menu appears.
    Partition and Format the hard drive:
    1. Select Disk Utility from the main menu and click on the Continue button.
    2. After DU loads select your newly installed hard drive (this is the entry with the mfgr.'s ID and size) from the left side list. Click on the Partition tab in the DU main window.
    3. Under the Volume Scheme heading set the number of partitions from the drop down menu to one. Click on the Options button, set the partition scheme to GUID then click on the OK button. Set the format type to Mac OS Extended (Journaled.) Click on the Partition button and wait until the process has completed. Quit DU and return to the main menu.
    Reinstall Lion/Mountain Lion. Mavericks: Select Reinstall Lion/Mountain Lion, Mavericks and click on the Install button. Be sure to select the correct drive to use if you have more than one.
    Note: You will need an active Internet connection. I suggest using Ethernet
                if possible because it is three times faster than wireless.
    This should restore the version of OS X originally pre-installed on the computer.

  • How to add a formula column in a report

    Hi
    I have made a report based on a query.
    There are 3 columns in the query and all the 3 are displayed.
    Now I want to add a new column (fomula column) to the report.
    I want to write a query inside the formula column. To execute the query col1, col2 and col3 values are required in the formula column.
    Could you please tell me how to add a formula column in the report and how to pass database column value to inside the formula column
    regards

    Here is how you would create a formula column:
    Open data model of the report.
    Formula column button is on the left side of the tool palette.
    Click on that button.
    Now click in the query group where you want to place the formula column.
    You would see a new field something like CF_1. That is the formula column.
    Double click on the field CF_1. It will open property inspector.
    You would see, Datatype of the formula column is Number. Change this as per your requirement.
    Double click on PL/SQL Formula property. It would open up a editor. Here you can write the code.
    And now to access the data model column here, you can use : and column name. i.e. :col1 or :col2, etc
    And remember you have to return the value back to the formula column. Like this: RETURN(some value).
    You can also take a help from here:

  • How to add a tip to flexfield columns

    How to add shorttip to Flex: (BankDetails) columns/segments. I know how to add shortip if it is a messtext input, I would like to know is there a way to add shorttip to Flexfield columns using personalizations.

    There seems to be no way for adding tip for a single segment using personalization.
    FYI:
    1. For whole region you can add a tip by creating a tip item just under flex item.
    2. Using controller, get the handle of any single segment. Then use the below method:
    oamessagetextinputbean.setLongTip()

  • How to Add the Dynamic List Wizard Form to a Spry Accordion Panel?

    Is it possible to add ADDT Dynamic Forms to the Spry Widgets?
    - I have been trying to add the Dynamic List Wizard to my existing Accordion but everytime I do, the Accordion turns into plain text?
    -Also, If it is possible then how do I target the Panels and have the detail record open up in Panel number 2?
    I plan on having the ADDT Dynamic Form in Panel 1, and want the Add, Edit, New, Delete form to open up in Panel 2.
    Thanks for your help,
    jlig

    I figured this out.
    1) First add all the Fields to the Form using the ADDT Insert Record Form Wizard.
    2) View the ADDT form in the browser to make sure the fields all display.
    3) In DW design view, move the cursor just to the left of the ADDT Form and hit Enter to Add a line just above the ADDT Table.
    4) With the cursor below the Red Form line and just above the ADDT table add the SPRY widget. (ex..Tabs)
    5) Now highlight the rows you want to move & hit Cut, then open up Tab1, highlight Content1 and hit Paste.
    I decide to leave my date_added, modified_By & date_modified fields below the SPRY tab widget so that these fields are visible all the time. When I click on the Insert button, the record was added correctly to my Table after Validation passed.
    Thanks,
