I bought [Iiyama XB2783HSU-B1DP](http://www.iiyama.com/gb_en/products/prolite-xb2783hsu-b1dp/) monitor. However I'm not able to connect my MacBook Pro 2015 from HDMI with [DisplayPort to HDMI](https://www.alza.co.uk/roline-displayport-hdmi-connection-shielded-2-m-d504901.htm?catid=18848641) cable. From monitor menu I am able to select DisplayPort, but monitor will fail to receive any signal from laptop. I tried to connect monitor with Asus laptop, DisplayPort no signal again, while connection through VGA port works fine. Any advice?

Does anyone can recommend some application to play Blu-ray on pc? I have CyberLink PowerDVD 8 that came with optical drive, but often there is a lag (visible stop in playback). I would love if VLC player people added BR support to application, but at the moment libbluray is more of trouble then success

Simple code to see if array of primitives has duplicates. The aim is to only check if there are any duplicates, but not to check what element is repeated, or its position etc. PS: Do you know some handy snippet? Don't way, post it!

Two ints and a float are in a bar. They spot an attractive double on her own. The first int walks up to her. “Hey, baby”, he says, “my VM or yours”. She slaps him and he walks back dejected. The second int walks over. “Hey, cute-stuff, can I lick your Bean?”. After a quick slapping, he too walks back. The float then ambles over casually. “Were those two primitive types bothering you?”, he remarks. “Yes. I’m so glad you’re here”, she says. “They just had no Class!”

Since we are already mentioned in [URL="https://github.com/search?q=daniweb&type=Everything&repo=&langOverride=&start_value=1"]few projects[/URL] ;) could we get official account where we may actually upload tutorials and link them in posts? That will also mean that someone will have to actively monitored or perhaps mods or selected members would be contributors.

Sometimes one line of tool tip is not enough. You may want to try and play around with JToolTip, but if you in hurry this "little hack" can be handy. With little of HTML plus CSS code you can work out various formats (font, colour, alignment, size etc.).

I have VLC running on my laptop which does happily plays CDs and movies on the local disk. However I'm not able to play DVDs. In the Preferences under Input & Codecs Settings where default disk device can be set I'm getting 2 question marks in diamond shape and the browse button next to text field doesn't respond. I have distinct feeling that Ubuntu is not picking my DVD driver correctly and misplacing it with CD drive. Suggestion how to solve this issue?

Would be possible to create "generic" sub-forum in Databases where we can place any db related stuff which doesn't fit into any of our present options?(MySQL, MS SQL, Oracle, MS Access and FileMaker Pro, Database Desing) Having something similar to Software Development sub-forum Legacy and Other Languages. Reason: Often there is no real place to move questions on SQLite, Derby, DB2, HSQLDB, Postgres, MongoDB and many others and have to leave them either in Software Development section with language they are used or IT Professionals' lounge. This is pointless specially if asked question is on user or admin side instead …

I have table something like [ID, ITEM_ID, URI, IMAGE_FILE_NAME, UPDATED_AT etc.]. I need to compare URI that can be something like /system/images/777/medium/Debrecen_-_University.jpg?1279547675 with IMAGE_FILE_NAME that is as Debrecen_-_Protestant_Great_Church.jpg Is there a way so I can provide IMAGE_FILE_NAME as sort of substring of URI and check if that substring is part of the string?

In my current project we need to provide drag&drop functionality of items from left to right and vice-versa and on click of the button send array of item IDs to server. Main problem was that we couldn't get array across to server and online examples that we found did not work. Above snippet will grab "id" attribute of all list elements (order/unorder list) from container with ID of "sortable2". Push IDs from listed elements to array "ids". After that, it will get currently selected value from drop down menu and store it in "id" variable that is used in next …
