Pro: in RF Development how can i get the scaned barcode value to Tcode
Hi,
I need to develop a custom RF settings for Scaner. I have gone through the SAP Provided documentation. SAP Has given in report we need to call Screen.
Every thing is clear for me... creating report, screen, triggering messages, customization.. etc. <b>My question</b> is what are naming conventions i need to use. it's custom Transaction. When ever we scan the Barcode, how that value is passing to initial screen of my Program. how can i keep it in SAP Memory. once after getting the value it's anormal transaction. i can code for that. how can i get the scaned value.
Hi!
Most (of my) customers use their scanners in keyboard simulation mode. Than it's like typing the number (or character) of the barcode. -> You need an input (char) field. Most (all?) scanners can be programmed to add a constant at the end -> use 'enter' and you get your PAI triggered.
Then scanning is same as typing 11 (or 13 or whatever) numbers on keyboard.
Other option would be, using scanner in native mode. But then you need a kind of device driver, which calls SAP via RFC. Possible, but more complex (because of missing alternative 'keyboard' in case of trouble).
What happens, if scanner can't read barcode, but user can identify numbers below -> you need anyway char-input field reacting on keyboard, too.

Christian

How can i get the all values from the Property file to Hashtable?
how can i get the all values from the Property file to Hashtable?
ok,consider my property file name is pro.PROPERTIES
and it contain
8326=sun developer
4306=sun java developer
3943=java developer
how can i get the all keys & values from the pro.PROPERTIES to hashtable
plz help guys..............The Properties class is already a subclass of Hashtable. So if you have a Properties object, you already have a Hashtable. So all you need to do is the first part of that:Properties props = new Properties();
InputStream is = new FileInputStream("tivoli.properties");
props.load(is); -

How can I get the phone numbers in contacts to appear with dashes between the first 3 numbers, the next 3 numbers, and the last 4 numbers? Until very recently
it did so. Contacts on my macbook pro does show up this way. I do have a mobile me account and in the past syncing was no problem. What setting has changed?The phone number format as well as the date language and format and the time format are controlled by the Region Format setting. Go to Settings > General >International > Region Format. When you change a region format, you can go back one page (to International) and see an example of the date/time/phone number format that your selected region format will produce.

How can I get the old view of iCal back on my MacBook Pro and iPhone?
How can I get the old view of iCal back on my MacBook Pro and iPhone? The Mavrick version is crisp and clean but a colored dot is not the same as a highlighted word. I rely on my iCal on my MacBook Pro and iPhone 5 to help me track which of the 8 sites I visit for my job during the week - the color coding is (was key) to organizing and tracking meetings. I hate the upgrade!
If purchased through the Mac App Store then it can be installed on up to five authorized CPUs. Otherwise, it's controlled by the license that came with the software.
To install on another computer copy the downloaded installer application to the other computer. -

I have a Mac Pro OS 10.7.5 and have a DVD+R disc with files on it, but it ejects the disk after about 10 seconds--what to do? How can I get the data off this disc? I can see it has been already burned, so files are on there?
Try cleaning the lens and see if that will restore functionality to the DVD drive. Use a DVD lens cleaning disk, if you have a can of compressed air, shoot some into the slot or wrap a fine microfiber cloth (eyeglasses cleaning cloth) around a business card and insert it gently inside the slot.
If no success, make an appointment at an Apple store genius bar and get a free diagnosis from them.

I am trying to import standard midi file that I created in Band in a Box into Logic Pro 9. I can not get all the track to play with internal instrument sounds... only the piano track. how can I get the others to play... drums, bass etc???? Help
Don't drag the midi into an open Logic project. The tracks won't set up correctly.
'Open' the midi file with Logic as if it were a Logic project. Then all the tracks will be set up so you can start editing them and applying better saved sounds and instruments, but you'll be at a starting place where you can hear what's going on. -

I purchased Adobe Acrobat x Pro recently and installed it, I have compatibility issues vision 2013. The adobe pdf converter plug in stays inactive despite all my efforts to activate it, I need help with this? How can i get the plug in to work with Visio 2013?
For MS Visio (any version) only the appropriate version of Acrobat *PRO* provides PDFMaker for Visio.
For Visio 2013 specifically you must have Acrobat XI Pro (updated to at least 11.0.1).
