I am an Indian working in Central Government and have applied for an Italian tourist visa for 17 days (to visit Rome-florence-paris-Vience-Rome-India). But my visa application got rejected with the reason "information submitted regarding the justification for the purpose and condition of intended stay is not reliable".  I have already submitted my original tickets to and from Italy and online hotel bookings, my salary slip, form 16 of the last 3 years, bank statement showing a good amount, nOC form employer and all the other relevant documents. May I know what the reason of refusal is and how I can get it corrected?
Schengen refusal formulae can be difficult to understand sometimes.  Sometimes an applicant receives a refusal with:       Justification for the purpose and conditions of the intended stay was not reliable.     often accompanied by:       Your intention to leave the territory of the Member States before the expiry of the visa applied for could not be ascertained.   What is meant by this refusal reason?  What are they trying to say?
Nvidia graphics card no longer works in Windows 10 (error: Code 43) but works in Ubuntu Currently, when I boot into Windows, one monitor stays black (undetected), and the other can only display 800x600 resolution.  When I look at Device Manager &gt; Display Adapters &gt; NVIDIA GeForce GTX 970 &gt; General &gt; Device Status, it says "Windows has stopped this device because it has reported problems. (Code 43)".  Details &gt; Problem Code says "00002b". Details &gt; Status says:  01802400 DN_HAS_PROBLEM DN_DISABLEABLE DN_NT_ENUMERATOR DN_NT_DRIVER   When I then click into the Events tab, it says "Device PCI\VEN_10DE&amp;DEV_13C2&amp;SUBSYS_29763842&amp;REV_A1\4&amp;25438c51&amp;0&amp;0008 requires further installation."  I have a EVGA Nvidia GeForce GTX 970 graphics card with the latest drivers (376.19 from 12/1/2016).  My Windows 10 Pro has the latest updates and is at Version 1607, OS Build 14393.576.  My ASRock Z170 Pro4 motherboard BIOS is also updated to the latest version (7.00 from 10/4/2016).  I have dual Acer monitors with 1920x1080 resolution.  I downloaded Ubuntu 16.04.1 LTS onto a bootable USB drive and booted into the Ubuntu operating system instead of Windows. Both monitors immediately worked at full 1920x1080 resolution. So the hardware seems functional! My remaining challenge is to figure out why my video card has stopped working within Windows.  What I Have Tried   I've tried using Display Driver Uninstaller from Guru3d in Safe Mode to delete all drivers and try to install fresh.   I've tried many different versions of the driver dating back more than 12 months. I've tried reseating the card. I've tried moving the card to a different slot. EVGA's phone support told me to reinstall windows (Windows &gt; Reset this PC &gt; Keep my files). Unfortunately, I followed their advice (and now don't have any of my programs), and I still get Code 43 with the EVGA Nvidia card.   What I Have NOT Tried   I would love to try installing this card onto a different Windows 10 computer to see what happens, but I don't have access to any other computers. If you live northeast of Atlanta, let me know. ;-)   I'd appreciate any other ideas you have!. A "friends list" on Stack Overflow would be nice I think it would be nice to have a "friends list" on Stack Overflow. This would allow us to be able to follow the questions and answers that are posted by users that we want to watch/monitor.  I suggest it be implemented in the same fashion as DotNetKicks.com; where you can add someone to your "friends list" without them needing to approve you the way that other social networks do it. It should be completely open for us to add anyone to our "friends list" that we like. Why is it that scanf() needs the l in "%lf" when reading a double, when printf() can use "%f" regardless of whether its argument is a double or a float?  Example code:  double d; scanf("%lf", &amp;d); printf("%f", d); Is there a keyboard command for 'show desktop'? Like Windows, I want to hit Super+D to jump to the desktop or minimize all windows. I don't see command like that in Keyboard Shortcuts. Any idea? Who are the Steam Mascots? So with the Steam Summer Sale in full swing, I've finally taken notice of the Steam Mascots.  Judging by the latest background, the black one, at least, has a name: Cyl.  Do the other two have names as well? Are there only these three?   What's their story? Counterexample to Leibniz criterion for alternating series I have this statement and I need to say if it is true or false:  Let $\{a_n\}$ be a real sequence.  $$\lim_{n\to +\infty} a_n = 0 \quad \implies \quad \sum_{n=1}^{\infty}(-1)^na_n \quad \text{converges}$$  I know, from the Leibniz criterion that:     If $a_n \to 0$, $a_n$ is decreasing and positive then $\sum_{n=1}^{\infty}(-1)^na_n$ converges   From this fact I believe that the statement is false but I couldn't come up with an infinitesimal sequence that isn't decreasing and for that reason is divergent. I tried some function with $sin(\frac{1}{n})$ without any luck. Any help would be very appreciated, thank you! I have a string "1112224444' it is a telephone number. I want to format as 111-222-4444 before I store it in a file. It is on a datarecord and I would prefer to be able to do this without assigning a new variable.  I was thinking:  String.Format("{0:###-###-####}", i["MyPhone"].ToString() );   but that does not seem to do the trick.  ** UPDATE **  Ok. I went with this solution  Convert.ToInt64(i["Customer Phone"]).ToString("###-###-#### ####")   Now its gets messed up when the extension is less than 4 digits. It will fill in the numbers from the right. so  1112224444 333  becomes  11-221-244 3334   Any ideas? Is there a terminal command that will log you out of your current desktop session and take you back to the login screen? What are the requirements to use iMac screen as a second monitor - Target Display Mode? I have a Surface Pro 4 and an iMac (late 2019).

SQL Server: Examples of PIVOTing String data Trying to find some simple SQL Server PIVOT examples.  Most of the examples that I have found involve counting or summing up numbers.  I just want to pivot some string data.  For example, I have a query returning the following.  Action1 VIEW   Action1 EDIT   Action2 VIEW   Action3 VIEW   Action3 EDIT     I would like to use PIVOT (if even possible) to make the results like so:  Action1 VIEW EDIT   Action2 VIEW NULL   Action3 VIEW EDIT     Is this even possible with the PIVOT functionality? Suppress a biblatex field in only one of split bibliographies? I am aware of \clearfield, \clearlist etc (cf. ) - but I'm really not sure how to apply it in this context:  Say you have a split bibliography (i.e. several calls to \printbibliography in one document). How can you filter a specific field in a bibliography item - but only in one bibliography (i.e. only in one call to \printbibliography)?  For instance, in the MWE below (compiles with pdflatex test.tex &amp;&amp; biber test &amp;&amp; pdflatex test.tex &amp;&amp; pdflatex test.tex), let's say I'd like to filter urldate (i.e. urldate is not typeset) only in the first bibliography - but for the second one, the original/default behavior should be restored (i.e. urldate is typeset). How to I do that?  \documentclass{article} \usepackage{filecontents} \begin{filecontents*}{\jobname.bib} @online{ctan,   title        = {CTAN},   date         = 2006,   url          = {http://www.ctan.org},   subtitle     = {The Comprehensive TeX Archive Network},   urldate      = {2006-10-01},   label        = {CTAN},   langid       = {english},   langidopts   = {variant=american}, } @misc{google,   title        = {Google},   date         = 2007,   url          = {http://www.google.com},   urldate      = {2007-10-01}, } @misc{hotmail,   title        = {Hotmail},   date         = 2008,   url          = {http://www.hotmail.com},   urldate      = {2008-10-01}, } @misc{yahoo,   title        = {Yahoo},   date         = 2009,   url          = {http://www.yahoo.com},   urldate      = {2009-10-01}, } @misc{aol,   title        = {AOL},   date         = 2010,   url          = {http://www.aol.com},   urldate      = {2010-10-01}, } @misc{altavista,   title        = {AltaVista},   date         = 2011,   url          = {http://www.altavista.com},   urldate      = {2011-10-01}, } \end{filecontents*} \usepackage[utf8]{inputenc} \usepackage[backend=biber,defernumbers=true,style=ieee]{biblatex} \bibliography{\jobname}  \begin{document}  \section{Section 1} \begin{refsection}  Citing some stuff here: first \cite{ctan}, then \cite{google}, and finally \cite{hotmail}.  \printbibliography[sorting=none,section=\therefsection,resetnumbers=true]  \end{refsection}  \section{Section 2} \begin{refsection}  Citing some stuff here: first \cite{yahoo}, then \cite{aol}, and finally \cite{altavista}.  \printbibliography[sorting=none,section=\therefsection,resetnumbers=true]  \end{refsection}  \end{document}   Output: I was looking for a derivation of the expression for the energy density at any point in a static magnetic field. I do know that it is  $$u_B=\dfrac {1}{2 \mu_0}\left|\mathbf{B}\right|^2,$$ I was just wondering if there was a derivation that could be built up the way one derives the energy density, $$u_E=\dfrac {\epsilon_0}{2}\left|\mathbf{E}\right|^2$$ at any point in an electric field, by considering the energy needed to build up a 'source' charge bit by infinitesimal bit.  Whatever proof I have come across seems to bring inductance into the picture -- is there a way of doing it without that? I ask because the corresponding proof for the electric field does not seem to need the definition of capacitance anywhere. Is there any relation between the chromatic number of a graph $G$ and its complement $G'$ that are always true?  I saw these ones: $\chi(G)\chi(G')\geq n$ and $\chi(G)+\chi(G')\geq 2n$,  but I'm not pretty sure about them.
