• fgetc reports ' argument open stream ", the fopen() function succeeded

  Hello

  I'm looking to implement the GNU 'getline()' function in CVI and the function starts as:

  getline.dll:

  Ssize_t getline WINAPI LIBAPI (char * lineptr, size_t * n, FILE * stream) {}

  int c;

  While (TRUE) {}

  c = fgetc (stream);    Error occurs here

  ...

  }

  }

  (LIBAPI is DLLEXPORT or DLLIMPORT). It is then compiled as a DLL and put it somewhere in the world. Then I have another DLL that does this:

  Driver.dll:

  int ReadWaveform (void) {}

  FILE * fwave;

  char * lineptr = NULL;

  int n = 0;

  fwave = fopen ("waveform.txt", "r");

  Len = getline (& lineptr, & n, fwave);

  ...

  }

  I get the error "Argument must be an open stream" when the 'fgetc()' function is called. It does not produce an error if this fgetc() is put in the ReadWaveform() function. The file exists, it is readable (the permissions of files are read-only, but read/write changes its behavior either). The two libraries are compiled in debug (or the getline.dll has also been compiled as a liberation, but does not change because the file can not be read and fgetc() reports EOF immediately that it should in case of error).

  So there seems to be some issues to limit cross-DLL when using file streams if open the stream in the DLL driver.dll and work with her in getline.dll. I did not have this problem with other C languages.

  any help on this would be appreciated. I use CVI 9.0 on Windows XP.

  Thank you

  Jason.

  I think this problem is the same as malloc/free deliver you in the other thread. Basically, I think that your two dll is built with runtime different support options, and so, engine running different CVI DLLs are called to manage resources. If you build your dll/program with the same runtime support option, then you should be able to share the FILE pointer through modules - you can't always do it for other reasons of design.

• SetCtrlVal used during the Thread function works causes memory leaks

  I am writing a program that works if... Or not work if... - see the next lines... :-)...

  The program includes a section, mostly GUI - and User Interaction.

  The other part is a DLL. In the DLL we readings on an external consultant controller RS232. Sometimes the controller card needs (called how much) time and this time must pass then the result can be read card controller... and so on...

  Blocking is not GUI-user-program for the expectation of the return value of the DLL functions (which need a few seconds to be finished) I start a thread in the DLL with

  CmtScheduleThreadPoolFunction (DEFAULT_THREAD_POOL_HANDLE, THREAD_FunctionX, & tmpTFP, NULL);

  with "tmpTFP" as an instance of type "TYPE_THREAD_FUNCTION_PARAMETERS":

  typedef struct
  {
  //
  int IntVal1;                // 1. Integer-Wert
  int IntVal2;                // 2. Integer-Wert

  } TYPE_THREAD_FUNCTION_PARAMETERS;

  In the GUI-user program - I get fast by default-return value of the thread start function.

  Then I asked the DLL (some global state variables are used for this) when it is finished.

  According to the map-controller (RS232) contacted the waiting time depends on the 'mood' of the controller card.

  In the DLL-mark of the GUI-user-program routine now everything works fine - without using "SetCtrlVal!"

  In my GUI, there is a text box of the info/comment for messages. If I do a few outputs user using 'SetCtrlVal' I always errors, caused by the false "TYPE_THREAD_FUNCTION_PARAMETERS"-values in the service of thread. "» If I set a breakpoint at the beginning thread-function I see mostly erroneous values in my transfer structure variables. If I put a breakpoint in the thread-function-calling 'CmtScheduleThreadPoolFunction (...)"and at the beginning of the thread values are (mostly) correct!

  I tried several and different things - but:

  If I ONLY (!)  Commenting on the (!) of a line with "SetCtrlVal", the program works, all States are asked out of the DLL.

  If I replace the "SetCtrlVal" with a written record-file function clean everything works fine and after completing the program I can look at the log file and see all the user information. BUT with 'SetCtrlVal' instead or set or (...) it does not work.

  My description is maybe not entirely clear, but believe me: only ONE line the «SetCtrlVal "line - should be commented out to let the program run properly!»

  Because if the line "SetCtrlVal"is program-user-GUI, after the call to the thread in the DLL, the DLL-memory seems to be corrupted by the call "SetCtrlVal" in the user-GUI program.»

  There may be a problem in your structure that your variable is set.

  You said that, after the address of the variable in the thread function the appellant one ends. Now, as you can read help each value passed in parameter threadFunctionData of the layed function must point to an area of memory that persist when the fuction is running: If your variable is defined at the level of the functions it is not valid when the thread runs since the appellant finished and released its local memory.

  Your approach with a global variable is a valid alternative, but if it is the solution, you will find data passed to the thread function must be valid for all his life.

• Search function does not work correctly (it does not mark the words found, instead, he built a light blue frame); When you open the PDF with Foxit, the search function works.

  Hello

  I use a PC (not a MAC). The document that I have a problem with emerged on a Word Document. I opened it using Adobe Acrobat Reader DC.

  When I tried to search for a Word, it worked. He scored the first word matching my search. As I pressed Enter to get results, he built a clear blue frame around large parts of the text presenting the result somewhere in the framework:

  

  When more pressing enter, the frame moves to the right or expands, but no other match is found. I tried to open the same file with Foxit pdf and here the function works correctly (marking all the matches one by one).

  Unfortunately, I can't tell all my customers to use Foxit. They all use Adobe and are complained about the search function.

  The size of the document is 9,32 MB and contains 324 pages.

  Thanks in advance for your help.

• Why is the hitTest function works only with attachmovie?

  Hello.

  I need help. I can't get the hitTest to work for my script below.

  I tested using movieclips created on stage at design-time and collided during execution. hitTest, works very well in this situation.

  But if I use the attachmovie command and create a movie on stage during the performance, the video cannot hitTest with other clips. The hitTest just doesn't work.

  Please help me by recommending changes. I don't know what to do. It is not that difficult.

  Thank you.

  """"""""""""""""""""

  The script below is essentially to create instances of enemymc, and he will fall vertically, hitting a movieclip target_mc which is set at design time. Please help, out of ideas.

  """""""""""""""""""""

  var enemyTime:Number = 0;

  var enemyLimit:Number = 20;

  onEnterFrame = Function)

  {

  enemyTime ++;

  trace (enemyTime);

  if(enemyTime == enemyLimit)

  {

  var enID: Number = Math.Random ();

  enemy_mc = _root.attachMovie ('enemymc', 'en' + enID, _root.getNextHighestDepth ());

  ["fr" + enID] _root ._x = int (Math.random () * Stage.width);

  _root ["fr" + enID] ._y = - 5;

  _root ["fr" + enID] .onEnterFrame = function()

  {

  var chk:Boolean = false;

  var currMov:MovieClip;

  ce ._y += 5 ;

  currMov = this;

  if (this.hitTest (_root.target_mc, true))

  {

  trace ("the enemy detected a success.");

  }

  if (this ._y > (Stage.height - 10))

  {

  this.removeMovieClip ();

  }

  }

  enemyTime = 0;

  }

  }

  If you have two targets mc then they must have different instance names and you must hitTest for each of them.

  If (this.) HitTest (target_mc1) | this.hitTest (target_mc2))
  {
  trace ("the enemy detected a success.");
  }

  And if you need to deal with them in different ways depending on who gets the success, just use two separate tests.

  As far as why my way and not your way, I have to be honest and say that I spent time trying to get your way to work and by trial and error, I ended up with, that's what you see.  I thought that the biggest change took place (which means he started work) when I changed the hitTest to not include the "true" setting, which I think is applicable to the use of corrdinates, and not an object.  But when I started your code and changed only this line, it still does not work, so something else in my revised code also applies.

  I didn't like using the random calculation for falling objects, which may have been part of the problem.  That will produce a fractional value with a point decimal, and names of the instance with dots in them are probably an accident waiting to happen (ex: en0.27365514)

  If you want to know what changes were absolutely necessary for its work, start with your code and the hitTest change first and then see what must be done to get things working properly.  I was tempted, but I had other things I wanted to do, so I got what I got the job.

  Maraarto

  ==============================================
  What is the exact name of the viewer you are using?

  If you are referring to Windows Picture and Fax Viewer... it made
  not a resizing function. You can zoom in to look at one, but that
  cannot be saved. It has a rotate option and that
  must be permanent.

  If you make resize them and rotate in an Image functions
  Editing program... the result should be permanently recorded.
  Try... Save under... and the modified version of the give a new name.

  To resize... the free ImageResizer PowerToy can be very useful:

  Click on the following link and the left click of the
  PowerToys tab...

  Windows XP downloads
  http://Windows.Microsoft.com/en-us/Windows/downloads/Windows-XP

  (FWIW... it's always a good idea to create a system)
  Restore point before installing software or updates)

  Download and install: ImageResizer.exe
  (Filename: ImageResizerPowertoySetup.exe)
  (does not work on Vista)

  Then, you can open any folder containing
  images and you will have an option to resize.
  Just right click the selected image files and
  Choose resize images in the menu. You
  can select a picture or an entire group.

  The program will place the resized in copies
  the folder with your originals.
  (Tip: * never * overwrite your originals)

  To ensure that images in both portrait and
  landscape orientation are resized to the
  same dimensions... go to... Advanced...
  and enter the largest number in these two areas.
  IOW... for 600 x 800... Enter 800 in these two areas.

• Using the interval function works well for the end of the month

  
  I need to be able to get 1 year, 2 years, etc and also 1 month 2 months ago for each date in the calendar.  I can use the function of the INTERVAL for the most part, but it does not work if there is 1 month (year) would produce an invalid date.

  For example, the monitoring generates an error.

  Select TO_DATE (February 29, 2012 ')- INTERVAL of '1' YEAR  FROM DUAL; 

  Select TO_DATE('31-MAR-2011') - MONTH INTERVAL '1' FROM DUAL;

  Is there a way to get chosen to return on February 28, 2011?

  Thank you for your help.

  Sandy

  Hi, Sandy,

  ADD_MONTHs always returns a valid DATE.

  ADD_MONTHS (TO_DATE ((29 février 2012 ', «DD-MON-YYYY»), 12 * n))

  will return on February 29, n years after 2012, if this year is a leap year and February 28 this year, if it is not a leap year.

  In general

  ADD_MONTHS (d, m)

  Returns the date months after DATE m d.  If d is located near the end of his month and months m months in the future is for several days, then ADD_MONTHS returns the last day of that month.  By example, if d is on 31 March and 1 m, then ADD_MONTHS returns the last day in April (1 month after March), because there is no day 31 in April.

• How can I get the shuffle function works?

  When I select shuffle songs, albums or playlists, my ipod continues to play the same song again and again.  How can I mix between songs (it's the third ipod I had and it has always worked before)

  There is a separate parameter called repeat (unrelated to the Shuffle setting).  It can be set to Repeat OFF (no repeat) Repeat ALL (repeat current list) or Repeat ONE (repeat current song).  I think you have to repeat the value Repeat ONE.

  This setting is on screen Now Playing on the iPod to an iPod with a touch screen.  Tap the screen to see repeat the setting button.  It looks like two arrows in a loop.  This time, it is probably blue with a little "1"; Tap change setting repeat (by blue without the '1' or not blue).

• Printer stopped printing, but the other functions work

  I have a 1536mfp that has worked very well for many years... no problem.  I installed a second printer about two months (Officejet Pro 8620) for printing of color presentations... no there was no problem until last week when the 1536 stopped printing.  A few times I turned it and turn it back on and it would print.  Then it stopped printing completely.  I've replaced the USB cable in case that's the problem.  I checked the ports and they work.  I can scan my computer the 1536, but when I print... nothing.

  I updated the drivers to check to see if this is the problem.  I've uninstalled and reinstalled the printer... but so far nothing has worked.  Anyone has any ideas at this point?

  Thank you

  CJM111

  I tried the first option and nothing... I thenk tried the second and found several files in that location as... I deleted these files and followed your direction; tried to print... nothing... got nothing else that a warning light flashing... off the printer, then turn it back on and deleted printing only and reproduced the document and WOW! It worked!

  Thank you for taking the time to help.  He appreciates a lot... quite frustrating when something works so well for so long and then nothing.  Have a great day.

• Using the data logged in an interface with the aggragate function

  Hello
  
  I'm trying to use logged data from a source table in one of my interfaces in ODI. The problem is that one of the mappings on the columns target implies a function (sum) overall. When I run the interface, I get an error saying not "a group by expression. I checked the code and found that the columns jrn_subscriber, jrn_flag, and jrn_date are included in the select statement, but not in the group by statement (the statement group contains only remiaining two columns of the target table).
  
  Is there a way to get around this? I have to manually change the km? If so how would I go to do it?
  
  Also I'm using Oracle GoldenGate JKM (OGG oracle for oracle).

  "ORA-00979"when the CDC feature (logging) using ODI with Modules of knowledge including the aggregate SQL function works [ID 424344.1]
  Updated 11 March 2009 Type status MODERATE PROBLEM

  In this Document
  Symptoms
  Cause
  Solution
  Alternatives:

  This document is available to you through process of rapid visibility (RaV) of the Oracle's Support and therefore was not subject to an independent technical review.

  Applies to:
  Oracle Data Integrator - Version: 3.2.03.01
  This problem can occur on any platform.
  Symptoms
  After successfully testing UI integration ODI using a function of aggregation such as MIN, MAX, SUM, it is necessary to implement change using tables of Journalized Data Capture operations.

  However, during the execution of the integration Interface to retrieve only records from Journalized, has problems to step load module loading knowledge data and the following message appears in the log of ODI:

  ORA-00979: not a GROUP BY expression
  Cause
  Using the two CDC - logging and functions of aggregation gives rise to complex problems.
  Solution

  Technically, there is a work around for this problem (see below).
  WARNING: Problem of engineers Oracle a severe cautioned that such a type of establishment may give results that are not what could be expected. This is related to how ODI logging is applied in the form of specific logging tables. In this case, the aggregate function works only on the subset that is stored (referenced) in the table of logging and on completeness of the Source table.

  We recommend that you avoid this type of integration set ups Interface.
  Alternatives:

  1. the problem is due to the JRN_ * missing columns in the clause of "group by" SQL generated.

  The work around is to duplicate the knowledge (LKM) loading Module and the clone, change step "Load Data" by editing the tab 'Source on command' and substituting the following statement:
  <%=odiRef.getGrpBy()%>

  with
  <%=odiRef.getGrpBy()%>
  <%if ((odiRef.getGrpBy().length() > 0) && (odiRef.getPop("HAS_JRN").equals("1"))) {%>
  JRN_FLAG, JRN_SUBSCRIBER, JRN_DATE
  <%}%>

  2. it is possible to develop two alternative solutions:

  (a) develop two separate and distinct integration Interfaces:

  * The first integration Interface loads the data into a temporary Table and specify aggregate functions to use in this initial integration Interface.
  * The second integration Interfaces uses the temporary Table as Source. Note that if you create the Table in the Interface, it is necessary to drag and drop Interface for integration into the Source Panel.

  (b) define the two connections to the database so that separate and distinct references to the Interface of two integration server Data Sources (one for the newspaper, one of the other Tables). In this case, the aggregate function will be executed on the schema of the Source.
