• Download all packages or just the sound with the latest dates?

  Hi, maybe it's a stupid question, but when you go to the drivers and it shows are all pilots who are selected to download to your laptop you wanted to install only those with the latest dates or each package that is there?

  Hello:

  You must install the driver with the most recent date if you are sure this is a driver that you are interested in.

• How to create two different smart albums with photos with the same date?

  I created a smart album by using 'Date is' and ' keyword is EAA.»  (The photos have a keyword like "EAA" or "Flower".  Photos of keyword EAA & flower have the same date.)  When I use "Corresponding to all" are has no pictures in the album.  When I use "Match any" all the photos are in the album - EAA & flower.  I would like an album with only pictures of CEA for that date and another album with photos of flower with the same date.

  I get the same answer.  I can get the date and to a key word to work with 'all' selected, but not date and keywords.  So you will need two smart albums: one with date and ECA ('all' selected) and the other with date and flowers ('all' selected).

  Use the file menu option ➙ new Smart Album.

• Is there a problem with the maximum size of the RAM for Satellite 320CDT?

  I have a 320CDT Satellite with the latest BIOS (v8.00) and Windows 98 Second edition installed. There are 32MB memory base and a 32 MB module in the single expansion slot. If I change it to a plug-in 64 MB I see that 64 MB of total memory reported, not 96 as expected; the specification for the machine indicates that the admissible maximum memory is 160 MB (32 MB base + 128MB expansion). Does anyone know if there is a problem with the maximum memory size for this model and if there is a solution or workaround? I need to know quickly, in order to decide if I should return the memory module to the vendor! Thanks a lot for any help, Peter

  Satellite 320CDT supports an internal memory of 32 MB and a single slot can be used!
  You can improve it to max 96 MB (32 + 64 MB)
  I found a few old memory modules. You can use the modules SODIMM 144 pin EDO PA2043U 32 MB or 64 MB PA2044U

• problem with the backup data in text file

  Hello

  The problem I am facing wihile, saving the data in the text file is that everytime when I'm slecting the path of the façade, data that are recorded are added with the previous data, not only in the new text, the new data set is saved but also, is there any previuos run for the program , the corresponding data is also present in this text file.

  However, when I change the same ''(file path) to 'constant' in the control block diagram, and then add the path of the file, it doesn't have this problem. Basically, changing the "file path" constant in the diagram of control block (so that it is displayed in the front panel) is at the origin of the problem.

  Help, please!

  Thank you

  Your shift on the loop Register For is not initialized. It will keep the value of the string since the last time that he performed. That initialize and it should solve your problem.

• DLL for LabWindows/CVI 8.0 with the bool data type

  Hello

  I want to use a new SWIR camera in LabWindows/CVI 8.0 (Windows XP 32bits).

  The company delivered with the camera produced a 32-bit dll by using Microsoft Visual C++ 2010. The .dll and .lib and .h files include a working SDK/API (some functions with the bool data type)

  Compilation-online syntax error, variable Boolean is not a data type in LabWindows/CVI 8.0

  Generate the import of DLL-online syntax error library

  I tried to convert bool char (typedef unsigned char bool => no more syntax error but the functions does not work.)

  What can I do?

  Martin

  Hello again, Naumann!

  Microsoft Visual C++ 2010 represents Boolean using 1 byte, as stated by MSDN: https://msdn.microsoft.com/en-us/library/tf4dy80a(v=vs.100).aspx

  I guess that you import C++ functions using the syntax for extern "C". Otherwise, because of the C++ name mangling wouldn't you able to bind C++ library against your code CVI.

  You can also specify how you import C++ functions?

  In addition, because you have not described the problem as a corruption of heads or runtime error, I guess the C++ library function is called correctly the CVI. That said, I tend to believe that the problem is not really in the mechanism of interaction of C/C++, but in the C++ library. If you would start calling a dummy C++ function returning an integer from a simple CVI application that should work, because redefine bool in CVI 1 byte must ensure that settings are correctly transferred onto the stack.

  If you need to create a wrapper function of C++ that is not using bool and calls the C++ function, I expect to return the same result.

  Maybe you are missing a few prior initialization steps required? The provider of the camera also comes all example code?

  Best regards!

• Insert/update the column with the clob data type

  Hi all

  ORCL Version: 11g.

  I have a table with the clob data type.

  Test12

  (col1 clob);

  I'm trying to insert/update to update the column with more than 4000 characters.

  But due to the limitation of tank 4000, I could not Insert/Update.

  Need your help in resolving this issue.

  THX

  Rod.

  The limit of 4000 characters is incorrect.  That pertains only to the varchar2 data type.  A clob can hold more than 4 G.

  Here is an example that shows how to insert it, I found...

  Otherwise, here is a way 'dirty' to do.

  insert into your_table (COLA, COLB)

  values

  (PRIMARY_KEY, PART 1 OF DATA)

  ;

  Update your_table

  Define COLB = COLB | PART 2 OF BIG DATA

  where COLA = PRIMARY_KEY;

  Update your_table

  Define COLB = COLB | PART 3 OF BIG DATA

  where COLA = PRIMARY_KEY;

  .. and so on...

  I don't know that I personally recommend the second style...  But he could do the job.

• Question about report with the format "Date."

  Hello friends! I want to make a line chart with a measure on the columns and type 'date' Format (MM/dd) data on lines and my report is invited with the type 'date '. In my dashboard page, I have a prompt with the Date and the operator is "BETWEEN".
  
  For example if I choose in my line of the first date: 01/01/2009 and the second date: 01/10/2009 in my chart, I see the results between these dates. But my question is... I see the same date last year? I mean if I choose the 01/01/2009 - 10/01/2009 I see this line and another line with 01/01/2008-01/10/2008. Is this possible?
  
  Because in my guest I can't type a variable presentation because date type is not taken care of...
  
  
  Thank you very much!!

  Let's say you have fresh measure
  then in your SPR you create logical column with the AGO formula (costs, TimeDim.YearLevel, 1)-Let's call him ' py 'measure.
  This will be your column YAGO...

  now in your report - you drop date, measure and measure columns py... it should work as long as you have the right size of set up time
