• Changing aid necessary table problem

  Hello. I hope someone can help me with this problem.
  
  I have two tables, an and mv. Create the following script:
  
  create table (mv)
  the moduleId Char (2) CONSTRAINT ck_moduleId CHECK (moduleId in ("M1", "M2", "M3", "M4', 'M5', 'M6', 'M7', 'M8'")).
  credit ck_credits Number (2) CONSTRAINT CHECK (credits (10, 20, 40));
  constraint pk_mv primary key (moduleId)
  );
  
  create table (its)
  stuId Char (2) CONSTRAINT ck_stuId CHECK (stuId ('S1', 'S2', 'S3', 'S4', 'S5')),
  moduleId tank (2),
  primary key constraint (stuId, moduleId) pk_sa,
  constraint fk_moduleid foreign key (moduleId) references (moduleId) mv
  );
  
  And the scripts below is to insert data into the two:
  
  insert into VALUES mv ("M1", 20)
  /
  insert into VALUES mv ("M2", 20)
  /
  insert into VALUES mv ("M3", 20)
  /
  insert into VALUES mv ("M4", 20)
  /
  Insert in mv VALUES ('M5', 40)
  /
  insert into VALUES mv ("M6", 10)
  /
  insert into VALUES mv ("M7", 10)
  /
  Insert in mv VALUES ('M8', 20)
  /
  
  
  insert into a VALUES ('S1', 'M1')
  /
  insert into a VALUES ('S1', 'M2')
  /
  insert into a VALUES ('S1', 'M3')
  /
  insert into a VALUES ('S2', 'M2')
  /
  insert into a VALUES ('S2', 'M4')
  /
  insert into a VALUES ('S2', 'M5')
  /
  insert into a VALUES ('S3', 'M1')
  /
  insert into a VALUES ('S3', 'M6')
  /
  
  Now for the real problems.
  
  First of all, I need to try to overcome the problem of table mutation ensure that stuid = S1 in table its can not take the two moduleId M5 and M6.
  
  Just one or the other. I created a single trigger, but runs aground because of the changing table problem.
  
  The second problem that I need to overcome is that none of the stuids can have the ModuleID where total value of more than 120 credit credits. Credit value is stored in the table of mv.
  
  Thank you very much in advance for any help.

  Use a statement-level trigger:

  I'm having a lot of problems with firefox and cannot figure out how to get help. It all started when I updated to 13.

These issues are causing me to use Chrome quite often, although I like Fox better. I've searched and searched how to get help and find nothing. How can I get personalized technical help? These problems will not occur in Chrome at all. Thank you.

  I fixed it!

So I went to my Plugins of PDF from Adobe folder, which in my case is C:\Program Files (x 86) \Adobe\Acrobat DC\Acrobat\plug_ins and delete the plugin ReadOutLoud.api.

• Windows xp routing table problem

  I'm having a problem with windows routing tables on the pc at my workplace.
  These computers are running windows xp sp3 and the problem occurs when I change the default gateway

  the PCs are on subnet 10.181.1.0/24 with d/g 10.181.1.11.
  with this configuration, the routing on each pc table works as expected [for example, it stores a
  Directions to its own subnet [10.181.1.0/24] but no way to other subnets [for example, it will not store
  a road to 10.180.1.0/24, it will simply send this default network traffic
  gateway].

  However, due to a re-design network, I need to change the default gateway for this lan
  to 10.181.1.254. When I do cela something strange happens. the windows routing table on
  each pc begins to store routes to the entire 10.0.0.0/8 network, even if the current
  config on the pc is still a 24 network [for example, 10.181.1.21/24, d/g 10.181.1.254].
  its as if when I change default gateway from the computer, windows, pleasures of the routing table of the
  10.181.1.0/24 subnet as if it were a network 10.0.0.0/8 classful.

  While, right? I can still connect to other networks, the pc is just using a route
  stored in its routing table local instead of sending traffic to its default gateway.
  The problem is that we have a 10.181.1.12 default backup gateway that we switch to
  If the primary gateway goes down. When we test failover to 10.181.1.12 pcs are always
  Send non-local traffic to 10.181.1.11 [because they still have these routes stored locally in their]
  Windows routing tables]. I want to send traffic to 10.181.1.254 [switch a core of layer 3, which then]
  two lanes of traffic to 10.181.1.11 or. [12]

  I tried to change the default gateway to a range of ip addresses and the same problem occurs every time.
  I rebooted each pc after having changed its d/g and the problem remains the same. I tried
  delete all the information off the power the pc ip address, then re-enter with the new d/g, then restart
  the pc but the problem remains the same.

  so, to summarize, when I change the d/g from any pc on the 10.181.1.0/24 subnet, computers table routing begins to store routes
  in its local routing table to the classful, instead of just the classless 10.181.1.0/24 network 10.0.0.0/8 network.

  Has anyone encountered this before?

But when we create the same group of XML data from a php/asp script on the web server, the Spry table flashes the model for a fraction of a second, and then deletes them. Web pages that contain the data sets are identical except for the source used by Spry.Data.XMLDataSet. No matter where he gets to it, the XML is identical. The XML file that we use has been generated by recording the output of the php/ASP script. The XML source file works, but the source script does not work.
  
  Example code:
  XML source: (this is generated by st.php and saved in st.xml, model based on DW CS3 Spry documentation)
  
  <? XML version = "1.0" encoding = "utf-8"? >
  <>sets
  < Game >
  < user_id > ZZZZ < / user_id >
  < grp_id > ABCD < / grp_id >
  < / set >
  < Game >
  < user_id > ZZZZ < / user_id >
  < grp_id > EFGH < / grp_id >
  < / set >
  < / sets >
  
  HTML: (here, everything is generated as DW CS3 has created, starting a new html file)
  
  <! DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional / / IN" " http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd" >

  < script type = "text/javascript" >
  var DS1 = new Spry.Data.XMLDataSet ("st.php", "sets/set");
  < /script >
  < / head >
  < body >
  < div spry: region = "ds1" >
  < table >
  < b >

  < /tr >
  < tr spry: repeat = "ds1" >
  < td > {user_id} < table >
  < td > {grp_id} < table >
  < /tr >
  < /table >
  < / div >
  < / body >
  < / html >
  
  -note: the "xmlns: spry" in the code above has an extra space between the slashes - I added that because the preview kept adding tags additional head in the middle of this address...
  
  The above html code uses "st.php" as a source for the dataset, and the only difference between the two tests is to change the source to 'st.xml '. I tried to look in all the documents that I can find, and the CS3 code corresponds to all the examples for the use of XML or a set of data source php/asp. Documentation seems to assume that it should simply work little matter that I use as a source as long as it outputs xml, which is what I do. I can check if the output itself works well because it made when registering in a direct xml file. Also, if I try to build the dataset schema, DW correctly interprets the output of the php script, exactly as it does when generating the schema from the xml file.
  
  We get this behavior if use us IIS, Apache, php, or asp, IE or Firefox. Obviously we are doing something wrong somewhere, but I can't find others with this problem, I can't find any options that could correct. Anyone has any ideas what could be the problem?

  You must use the ASP/PHP code to configure the mime type of the XML file as
  "application/xml".

• manipulation of the table problem

  I'm using Labview 2009 and I have a problem with windows... I have to implement the following code in Labview (X and digital input boards):

  for (i = 0 to MAX (X)) {}

  If (X [i] > (X [i-1] + 1)) {}

  X.Add (X [i], X [i-1] + 1) / / add the value X [i-1] + 1 x [i] position of the X table

  Y [i] = 0

  }

  on the other

  Y [i] = Y [i]

  }

  If I try to add items in the original array Y with the function 'Replace subset of table', the output array is not changed by the VI. If I try to initialize and to build a new table, I get a matrix of zeros. Can someone help me?

  If you want to just add 0 to the index that does not exist in X [] then try this.

• MS Office report Express VI and table problem

  Hi all

  I have a strange problem with MS Office report VI, which is included with the report generation tool. I created an Excel template that I linked, according to the preference "Custom template for Excel" and all the named ranges. However, two of the named ranges that I entered are 1 d arrays of doubles. Now the problem:

  When I entered the berries to their specific name range (it's only 6 values), instead of simply enter the values in the table in the cells he entries like this:

  A value of 0

  1 value

  2 the value

  ...

  6 value

  He pushes the 'value' to the column next to the beach of name because of 0-6.

  He does it with two tables so it screws to the top of all formulas. Anyone know how to remove the 0-6 and simply enter the values?

  Thank you all

  The Express VI are easy and convenient, but some costs. Since the Express VI can also accept a waveform entry, you have to accept that it will add a channel name.

  With the tool report generation (who are also its limits), it's easy to add only the data you want:

• simple table problem

  I have read some data from a text file and form a table according to my requirement (the illustrious photo attached).

  What my problem was when I used this table in an other vi through the connector components, all the lines in the resulting table the width of the line of maximum size, and are filled with zeros.

  How do I remove it? I need the lines ending with its own values, here in my case two first rows should have 5 items in the table, the elements of line 7 third and so on...

  

  Your VI makes no sense. Why not autoidenxing? Why "delete from table?

  Here's a simple possibility (just to write the resulting string in a file).

  

• Table problems

  Hello OR Forums, I currently develping a VI to specify the tensions that will be send to the device that will run two mirrors. The idea and the configuration are pretty basic, but programming, it's a question. Matrices X and there are elements that correspond to a point located on a network of coordinates. For example, maybe my items in my grid for X [-2, - 1, 0, 1, 2] and my Y could be [-2, -2, -2, -2, -2]. However, the problem is that I need a larger value of X and Y for I could resign in the grid and reassemble in table X. For example, will be my next line of items [-2, - 1, 0, 1, 2] X and [-3, - 3, -3, -3, -3] for Y. However, how my program is written my last value of is less than the previous item. Thus, ideally I would form a table that would have an extra X element that corresponds to the step down in voltage on the axis Y. This would be ideal: [-2, - 1, 0, 1, 2, 2] x and [-3,-3,-3,-3,-3,-4] for y.

  Sorry for this question is a bit bad made. The application of this program is quite simple, but it seems to me a bit puzzled.

  If you want to start (start X, start) then continue to start X + step X, start. Continue (Start, X, Y). Then go to start X, Y + step start o and increment in X. Repeat for all the table again.

  Is that a correct understanding of what you want?

  If so, you can do this with a picture of the X values and an array of the values, or even with no tables at all.  Create a State with the States for Scan X machine, trace, and no matter what States are required for initialization and shutdown.  Have two shift registers to track the values X and Y or indexes. Whenever you increment X through the State X Scan. When X reaches the maximum value or the index reached the last X, change the State to trace. It increments Y and restores X X start or equivalent for the index. When you reach Max X and Y of Max, go to the State of clean shutdown or restart.

  No complicated manipulation table required.
