Using forms to scan an image directly into the application.

I am not sure but my guess is this is possible in Forms but how, can I trigger a scanner or any other device (digital camera, etc) from Forms so I can populate image items directly from such devices instead of having to save to file and later use read_image_file built in.
null

simplest way I have done is creating an OLE type of Item and at run time we can insert an OlE server Application. I have used HP FLat Bed Scanner and after installing the Scanning Software the Scanner is shown in the 'Insert Object' List.
Another method is to call the external program using HOST command from a Button in Forms. This method is also ok. Works decently
But the ideal method would be to use DDE technique which fairly complex. I am not aware of the method.

    How do I import an image directly from the internet without printing and scanning it in first?

    You can also Ctrl click on the image, save the image to your desktop and open it in Photoshop.
    1.
    2.
    3. Open in Photoshop by double-clicking on the saved image on your Desktop or Cmd o in Photoshop.
    I don't see any point to copying and pasting from a browser into a new file in Photoshop.
    If you want to put an image onto an already open image in Photoshop, use the File > Place... command and select your saved image.

    Wanting to use Photoshop CS6 to open images directly from iPhoto 11.
    Using OSX10.8.2 and iPhoto 11.  Just installed Photoshop CS6 and want to open
    images directly from iPhoto.    Before I installed PS I was not able to edit photos
    in iPhoto 11.  Nothing happens when I click on ‘edit‘ it is blank. 
    And now it will not work using Photoshop CS6 either.
    From Help Center I have gone to iPhoto/Preferences/ Advanced and chosen Photoshop CS6  to Edit Photos but then cannot find an 'Open' to click? Perhaps this is the problem?
    When I select a photo in iPhoto and click the Edit button - nothing happens.
    Please advise. Glenys

    This may be of help to you:
    Using Photoshop or Photoshop Elements as Your Editor of Choice in iPhoto.
    1 - select Photoshop or Photoshop Elememts as your editor of choice in iPhoto's General Preference Section's under the "Edit photo:" menu.
    2 - double click on the thumbnail in iPhoto to open it in Photoshop.  When you're finished editing click on the Save button. If you immediately get the JPEG Options window make your selection (Baseline standard seems to be the most compatible jpeg format) and click on the OK button. Your done. 
    3 - however, if you get the navigation window
    that indicates that  PS wants to save it as a PS formatted file.  You'll need to either select JPEG from the menu and save (top image) or click on the desktop in the Navigation window (bottom image) and save it to the desktop for importing as a new photo.
    This method will let iPhoto know that the photo has been editied and will update the thumbnail file to reflect the edit..
    NOTE: With Photoshop Elements  the Saving File preferences should be configured as shown:
    I also suggest the Maximize PSD File Compatabilty be set to Always.  In PSE’s General preference pane set the Color Picker to Apple as shown:
    Note:  to switch between iPhoto and PS or PSE as the editor of choice Control (right)-click on the thumbnail and select either Edit in iPhoto or Edit in External Editor from the contextual menu. If you use iPhoto to edit more than PSE re-select iPhoto in the iPhoto General preference pane. Then iPhoto will be the default editor and you can use the contextual menu to select PSE for your editor when desired.

  • I'm trying to delete multiple pix in iPhoto that i stupidly made duplicates of without knowing, I've tried going into the applications folder and using image capture but i think I've missed a step , can anyone send the correct info / steps pls thanks

    I'm trying to delete multiple pix in iPhoto that i stupidly made duplicates of without knowing, I've tried going into the applications folder and using image capture but i think I've missed a step , can anyone send the correct info / steps pls thanks

    again image capture is not involved with deleting photos from iPhoto in any way ever
    the paid version of iPhoto Library Manager is very good for finding duplicates as is Duplicate Annihilator
    And I have no idea who told you this - or what it means - but re-read both of my opening statements
    I was told I could delete multpiles thru image capture by transferring my iPhoto library etc

  • I have a Cisco/Linksys WRT-54G wireless router and 2 Airport Extremes (the small ones that plug directly into the wall). Is it possible to extend the network from the router using these two AEs? I have a DVD player and Ext HD plugged into the router too..

    I have a Cisco/Linksys WRT-54G wireless router and 2 Airport Extremes (the small ones that plug directly into the wall). Is it possible to extend the network from the router using these two AEs? I have a DVD player and Ext HD plugged into the router too. Any ideas? I'm guessing the only way is to do what I've seen in these community pages which states that it can be done but it will drop the bandwidth by 50%. Thoughts?? Thanks!

    The Cisco/Linksys WRT-54G was one of the very few routers said to be compatible with Apple's implementation of WDS (Wireless Distribution System) settings.
    The info that I have on file indicates that only the WRT-54G versions 4 and under were compatible, so that would be one bridge to cross.
    Even if you find that your Cisco/Linksys might be the right version, Apple never published instructions on how to configure the Express devices with other manufactures, so users were left to their own devices to try to figure out how to get things working. Apple's instructions to connect to other Apple devices are in the link below:
    WDS network
    If you were hoping to use 2 Express devices in this type of configuration...even if it works...the bandwidth penalties will be extremely severe.
    The first Express drops the bandwidth (and speed) on the entire network in half and the second halves everything again. So, the result, in effect would be a "g" wireless network running at 25% speed. Few users would consider installing this type of network.
    At this point, it becomes one of those things where the fact that you might be able to do something does not mean that there would be much value in doing so. But, it is your decision to decide if you want to try to proceed.

  • Do I have to plug my ipad mini directly into the mains for a reliable charge?

    I've been having an issue with my new ipad mini not charging even when its plugged in using the mains adapter unless I plug it directly into the wall. This is a bit inconvienient as I don't have enough sockets and I like to use my ipad as a clock radio with TuneIn so when I wake up my battery is about 40% even though its been plugged in overnight.

    This is unclear and confusing...

    iPad Charging
    "The fastest way to charge your iPad is with the included USB Power Adapter.
    iPad will also charge, although more slowly, when attached to a computer with a high-power USB port (many recent Mac computers) or with an iPhone Power Adapter.
    When attached to a computer via a standard USB port (most PCs or older Mac computers) iPad will charge, but only when it's in sleep mode.
    Make sure your computer is on while charging iPad via USB. If iPad is connected to a computer that’s turned off or is in sleep or standby mode, the iPad battery will continue to drain."

  • Images burn into the screen after being there for only a few minutes?

    What's wrong with my mac if images burn into the screen after being there for only a few minutes?
    I can have an icon, like a folder or something, on my desktop for only a few minutes and then when I move it an image of it will be burned into the screen for another few minutes. Same thing happens with having a webpage open for a few minutes or word document. What part of my computer is malfunctioning and is Apple responsible for repairing it?

    Hi,
    Does it happen on all desktops applications as well as Modern UI Apps? Since this issue only happened recently, I suspect a newly-installed third party program causes this issue, please check these programs if possible.
    We can also boot into clean boot mode, test the issue.

  • Do I need an audio interface between my roland keyboard, garage band/MAC and Alesis 8.0multitrack mixer, or should I go direct into the USB of the Alesis with my keyboard into the mixer?

    Do I need an audio interface between my roland keyboard and alesis 8.0 multitrack mixer when interfacing with Garage Band? Or can I just go direct USB MAC into the Alesis Mixer with keyboard directly into the Mixer? ie, is the interface overkill?

    First of all the Alesis 8.0 is a usb audio interface so you already have a interface. Next you could go from the Roland into the Alesis into the Mac. You could also go from the Roland headphone or line out into the Mac Pro audio input. And depending on what Roland keyboard you have, you may be able to use Midi (usb) and use the Macs Midi voices.

  • How do I limit access of a computer that is plugged directly into the router?

    I have an AirPort Extreme, Version 7.6.1  I need to limit access of a computer that's plugged by usb directly into the router.  I have the MAC address for this computer and have had restrictions on it the in the past, but it was connected by WiFi then.  How do I do this?  Do I limit access to the Ethernet ID?  I don't want to lock myself out trying to figure it out; I did that last night.  Can someone advise please.

    You could use OpenDNS's parental controls:
    http://www.opendns.com/home-solutions/parental-controls
    It can restrict access according to your specifications for everyone on your network.
    It's free.

  • Is there a nonwireless headphone that plugs directly into the iPad? Thank you Artie

    Hi, name is Artie, I am not tech savvy, but am an old geezer. My kid is laughing at me for buying an iPad. I think my question is simple- is there a headphone that plugs directly into the iPad? I am interested in something cheap/simple that will allow me to watch shows/movies on the iPad while sitting on the couch with the Missus while she watches her shows on tv. I have a separate keyboard which is Bluetooth, but would prefer simple headphones so I can leave a pair at all the locations I will be using the iPad at, on a regular basis. Thank you Artie

    The iPad has a standard 3.5 mm headphone jack on it.
    Any set of headphones with a 3.5 mm jack will work.
    Thank you Johnathan, but I think I stated that pretty clearly: "you can use any stereo earphones with a 3.5 mm plug."

  • WiFi device that plugs directly into the USB slot on a printer?

    My next door neighbor has a MacBook with Airport installed.  She wants to use the portable around the house and send documents to a printer located in the basement.  She does not need a router to network additional devices, so what is the most reliable, reasonably priced device that plugs directly into the printer's USB port without the use of a cable (e.g. device with receiving antenna)?  Thanks.
    Bob

    Well, Badunit, it's more convenient and takes up less room if it plugs directly into the USB port, plus you save the cost of a cable unless one ships with the unit.  Here are two I found at Amazon:
    http://www.amazon.com/Compact-Wireless-802-11n-Newtork-Adapter/dp/B002VVITG8/ref =sr_1_6?ie=UTF8&qid=1311880281&sr=8-6
    http://www.amazon.com/802-11g-Wireless-Long-Rang-Network-Adapter/dp/B0035H4164/r ef=pd_cp_e_4
    Trouble is, they have too many negative reviews.  Besides, just how well do they work with the Airport Extreme card since most of these reviews are not Mac related, and those that are are negative?
    I'd like a device that is guaranteed to work well with the 2008 MacBook Airport card as the broadcast device.  Perhaps she will have to rely on a separate Linksys router with print server.

  • Maintain dimension members directly into the data base

    Hi,
    We need to update the dimension members directly into the data base.
    Instead of going into the administration and entering manually.
    I tried just updating the table mbr and dim. but that didn't work.
    Any insight on that?

    To update the dimension members from the backend tables, update the mbr<dimension>> table and process the dimension either from BPC Admin Console or a SSIS BPC Admin Task. The dimension processing will automatically update the dim<<dimension>> table in the backend.
    However, the updated dimension members can not be seen from the frontend in the BPC Admin. To see the updated dimension member sheet in the current client machine, use Export Dimension option in BPC Admin Console.
    To see the updated dimension an all client machines and get reflected in the current view, please follow this URL:
    Re: BPC 7 MS Update dimension (Make_dim task)
    Hope this helps.

  • TS3367 facetime microphone not working. i can hear the recieiver but they can't hear me. can hear if i talk directly into the microphone by turning the ipad round to the back, then the receiver can't see me!!!!!!

    the microphone on my ipad does not work for facetime. The person I am facetiming can see, but not hear me. if I go to the back of the ipad and speak directly into the microphone, they can hear, but obviously not see , as I'm at the back. HELP ! I CAN SEE AND HEAR THEM.

    I saw one post where a user said dust got in the small mic hole. Used a vacuum cleaner to remove and audio restored. Try it.

    It talks extensively about charging in the user guide, and how USB ports on PCs and older Macs may not provide sufficient power to charge the iPad.  The user guide is available for free from the iBook store (accessed directly via the iPad iBooks app).
    My iPad charges fine when plugged in to the back of my iMac, but I would always prefer to use the mains adaptor to save the strain on my USB circuits (which can wear out if used heavily to power external devices).
