• After saving a file PDF with a layer of Spot UV, all the highlights and details in the tones are flattened in the overprint preview. What I'm missing here?

  I'm trying to print business cards with a Spot UV coating. I have a layer above the work with a spot color (set to Green by request of the printer). Below is a logo, essentially a red circle with a few highlights and depth. My question is that, after exporting a PDF file, all of the highlights and details on the red circle disappear in the overprint preview (it is there when I hide Spot UV layer, but missing when I'm hiding the color of the task). What can I do to keep this information?

  Thank you!

  I managed to solve the problem and embarrass me in the process. It wasn't a problem with the settings, but rather a "stowaway" duplicate of a red circle that lurked on the layer UV Spot on top of all the details. Thanks for your help, but it seems that my problems require a different kind of forum!

• Why my front panel opens with a white background and most of the invisible control

  When I open my vi and several others, they open with a white background and most of the controls not returned as theis

  

  After I resize it looks like it should

  

  It's probably somewhat similar to these problems of crazy object.

  Sometimes copy/paste works because it takes your code on a VI that could have a corruption and put in a cool VI.  In your case, the corruption could be linked to the control itself and he just copied over in the new VI.  Money controls are a relatively recent creation which added some fancy appearances.  They don't seem to be the style that is most likely to have some behind the bugs of scenes from the styles of controls that were longer.

  If you have a shared services provider, or if a person nor jump here and wants to study, they want to can see your VI and understand what goes wrong.  If this isn't the case, I hope that what you've done has solved the problem and you can spend without return.

• Rewrite the query with joins, and group by

  Hello
  
  It's an interview question.

  When I was in College, I read most of SELECT statements can be replaced by operations base SQL (DEFINE the OPERATORS). Now, I am rewriting the query with SET operators, but not able to get the exact result.
  
  Kindly help me on this.

• Internal XML to the query with join

  I have a CF page that reads an XML file in a query using < cffile > XMLParse and QueryAddrow.

  I then do a QoQ on the result and voila! I have my page.  I hide the query for 8 hours and the XML file is only reread this cache expires.  It works well.

  My problem now is that the file contains data from three tables of database instead of one, so I need to make an inner join on the tables.  But I can't do a t/t with an inner join.

  Does anyone know a way for me to do this?

  Oh, didn't know that.  How about interweaving of QofQ?  Join Query1 and Query2 requests in a new query, then join for 3 statement?

• Update query with join statement

  Hi guys, would check how to write a query to update with the inner join statement? The case is like this, I need to update PRD_ID on TBL A as below, based on the information of lookup table. The keys are based on the A03 column to the table time to condition only select records in LOOKUP_TBL where PRD_ID = 110001 then update to TBL_A for those who match the data and FIX_FLT = 1

  I have an update query and it works in SQL SERVER but not in ORACLE

  Update a PRD_ID = B.PRD_ID set

  Inner TBL_A A join B LOOKUP_TBL

  On A.A03 = B.A03

  AND A.FIX_FLT = 1 AND B.PRD_ID = '110001';

  TBL_A

  PRD_ID	A03	FIX_FLT	TXN	DATE
  1	A1	1	1	23/10/2010
  1	A2	1	1	10/24/2010
  1	A3	3	2	10/25/2010
  1	A4	3	2	10/26/2010
  1	A5	3	1	27/10/2010

  LOOKUP_TBL

  PRD_ID	A03	NOTE
  110001	A1	NULL VALUE
  110001	A2	NULL VALUE
  110005	A3	NULL VALUE
  110005	A4	NULL VALUE
  110001	A5	NULL VALUE

  You can write updates like this in Oracle.  It's called updatable join views.  Something like this:

  Update
  (select a.prd_id a_prd_id
  b.prd_id b_prd_id
  Inner TBL_A A join B LOOKUP_TBL
  On A.A03 = B.A03
  AND A.FIX_FLT = 1 AND B.PRD_ID = '110001'
  )
  Set a_prd_id = b_prd_id;

  But you must have the constraints appropriate in place, otherwise you will get the error "key preserved table.

  The problem is now, if I limit the query about the h.hist_date, the lines disappear when there is no entry in HIST for this ALPHA_NR,
  in particular the line with alpha_nr = 12 disappears.

  When you use the old notation join, outer join, whenever a column of a table is marked with the + sign, then all the conditions in the WHERE clause that references the same table need a sign +. Otherwise, the effect is identical to an inner join.
  Using the old syntax, you must say something like:

  ...
  FROM       hist        h
  ,       alpha        a
  WHERE       h.hist_alpha_nr (+)     = a.alpha_nr
  AND       a.active          = 'Y'
  AND        a.alpha_nr          >=  1
  AND        a.alpha_nr           <=  10000
  AND        a.alpha_date           >=  TO_DATE ('01.01.2000', 'dd.mm.yyyy')
  AND        h.hist_date (+)     >=  TO_DATE ('01.01.2000', 'dd.mm.yyyy')
  AND       h.hist_date (+)     <=  TO_DATE ('02.02.2222', 'dd.mm.yyyy')
  ...
  

  Notice the + sign in the last 2 lines, after the columns in this table of reference h. I find the ANSI join syntax much more clear in this case.

  How you use NVL makes no sense. NVL (NULL, x) returns x, no matter what x is.
  What you trying to do? Perhaps you meant

  AND        NVL (a.alpha_nr, 1)          >=  1

  Yet, no network connection. Any help will be greatly appreciated.

  Hello

  Keep the changes and open the wireless. For example, to disable security in the router (turn on when to managed to connect).

  You can also try the wireless in a friends house, or an Internet café to get a frame of reference for this behavior elsewhere.

  -------------------

  Wi - Fi in general.

  These steps and tell us where is the breaking point.

  Check the Device Manager for the wireless card valid entry.

  http://www.ezlan.NET/Win7/net_dm.jpg

  If there is no valid entry, remove any entry from fake and re - install the drivers for the wireless card.

  Check network connections to make sure that you have a network icon/entry wireless connection, and that the properties of the icon (right-click on the icon) are correctly configured with the TCP/IPv4 protocol in the properties of network connections.

  http://www.ezlan.NET/Win7/net_connection_tcp.jpg

  ------------------

  The wireless card drivers much also install utility wireless of the seller.

  Make sure that if there are teas from Wireless Utility of seller does not work with the native Windows wireless utility (Service WLAN).

  ----------------

  Make sure you firewall No. preventing / blocks wireless components to join the network.

  Some 3rd party software firewall continue to block the same aspects it traffic Local, they are turned Off (disabled).

  If possible set up the firewall correctly, otherwise totally uninstall and get rid of its remaining processes that permit the own local network traffic flow.

  If the 3rd party software is uninstalled, or disables, make sure Windows native firewall is active .

  party like Hello and NetMagic 3rd network managers can block local traffic too.

  The date of the lease must be valid at the present time.

  * Note 1. IP that starts with 169.xxx.xxx.xxx isn't valid functional IP.

  * Note 2. There could be an IPv6 entries too. However, they are not functional for Internet or LAN traffic. They are necessary for Win 7 homegroup special configuration.

  ---------------------------------------------------

  A message in the small window that says connected wireless doesn't means that you are really a valid functional connection.

  Above everything is OK, you must be able to connect to the router.

  Connection to the router means that you can enter the IP of the router base in an address bar in one go, being able to connect and configure the router menus see.

  If it doesn't connect to the router, journal newspaper from any computer that can connect to the router wirelessly with a wire, disable wireless security, make sure that the wireless SSID broadcast is enabled and try to connect with no. wireless security.

  Enable security wireless after you eat to make a functional connection.
