• How Adobe Reader plugin Access database SQL?

  Hello

  I want to create a plugin for Reader version 9 and higher. The plugin must Access the SQL database to retrieve information. This information is displayed to the user in the form of a list.

  The user is then asked to select an element in the list. The plugin accesses the SQL database for the information based on the data selected by the user.

  I looked in the Adobe forum, who said that ADBC is frowned upon in Acrobat 9 and is completely deleted from Acrobat X. And that Adobe Reader requires Adobe LiveCycle Reader Extensions SS3 for connection to the base. All this is related to the presentation of the form to the server. My requirement does not include the shape or form data. I just want to access SQL database from a reader plugin.

  Is this possible?

  Can someone provide me with any documentation explaining how Reader plugin can interact with the SQL Server database?

  Thank you

  Technically, there is nothing for Adobe Document. If your plug-in wants to communicate with a server for any purpose, it can do so using whatever methods API are appropriate, and what protocols applications server; It's nothing specific to the treatment of the plug-in.

  The Acrobat SDK kit is available where you the form of plug-in interface. I don't know how to follow these steps.

  You will need to describe your proposed use to Adobe when you ask for a license to create plug-ins Reader. This is not automatic and can easily be denied. So apply early.  Of course, you are free to write plug-ins for Acrobat such unlicensed.

• Call of node on COM DLL can not configure the entry correctly

  I have a COM DLL, I try to use LV2013 32 bit. I managed to go as far as the ActiveX 'Automation open' and an invoke node. This makes me a list of parameters which resembles right (input and output), but I don't know that the real data types are correct.

  I have the DLL, a file header and an IDL file and 2 different bits of documentation (not everything agree).

  I am train to begin just to connect to the server by using the code below (see test Server Copnnect via dll.png)

  It does not work telling me that I have the incorrect input parameters.

  One of the pieces of documentation lists the parameters like:

  char * pConnection required

  long ITimeout optionally

  char * pOption in option

  but the idl file:

  HRESULT ConnectServer([in] CHAR *szPara)

  and the header file:

  virtual / * [helpstring] * / HRESULT STDMETHODCALLTYPE ConnectServer (/ * [in] * / CHAR __RPC_FAR * szPara) = 0;

  I would have thought the idl files and header would be more reliable but then why it the method has 3 parameters?

  Also the data types seem not fair.

  szPara must be a pointer which should be Unlt32 for a 32-bit program (which it is), but the data type reports as an I8 (8-bit integer). the szPara should contain txt connection such as "eth: 10.10.10.10:5000.

  I tried to create a string for the data pointer, but it does not work. I tried the typecasting of the I8 but that kills my data and I find zero to the dll. I tried then as above but the wind upward with points of constraint. I need to convert my multiple byte pointer? (Don't know how to do this).

  I looked at lots of other calls to invoke node in the same DLL and the direction of the setting always seems correct data types do not change (they are not all integer values, some report as real numbers) so it looks like the invoke node works but I do not know how to drive.

  Am I missing something obvious?

  Thank you very much

  A list of the function in the DLL names is also useful to diagnose the problem at hand as would be a list of random characters to understand one language: Niente, Nada!

  It's even worse than having just a header for a standard C DLL file, which can at least tell a little about the parameters, but C syntax is notoriously inadequate to describe the real API in a way disambigous.

  Here, ' char * name "can be a string, a single character, passed by reference, or a byte array. ' void * name "is even more ambiguous, since it could be basically anything! That's why Microsoft created ActiveX with a typelibrary interface that describes the functions much more in detail, and this typelibrary is LabVIEW (and Visual Basic and other languages 'Visual') has access to build the diagram nodes that have access to the methods and properties of an ActiveX object. If this type library is wrong there is nothing you can do in LabVIEW to make it work in any case except write a C++ wrapper that access the object ActiveX and translated them into a correct ActiveX interface. The reason is that end allows access to the typelibrary but as a descending C real also lets you do all the hard programming each detail explicitedly.

  As for your problem with the Denso library that will look much like the library in itself is bad, but that they forgot to certain attribute of the document or registry value that must be set in order to achieve unity of the robot in remote mode. Manufacturers of robotic are notorious for offering little support in access to their material to third-party applications. If they have a library at all so he has often paralyzed and hampered with these small disadvantages and problems.

  But trying to access an interface poorly documented to work around this limitation is very likely going to be an exercise even more frustrating. Simply being able to access their obviously badly designed interface you will probably run in a lot more problems. These interfaces at some point it will take magic numbers like parameter as save addresses to write specific values in and I'd be surprised if this documentation is more detailed on details such as the 'official' library is, what they offer for LabVIEW.

  You may want what all the bad talk about trying to take away the joy of having a fully working for your problem solution, but believe me, I've been there and dealt with the robotic interfaces and the only way that really works in the long term is to find the guy who knows and let them know what save the address must be tickled to make the LabVIEW interface works the way you want.

  An interesting industrial partner with a few good prospects for sales in which case it is possible to work of course helps a lot. Then sellers are sometimes more likely to continue to push the technical staff in the plant to spend a few minutes to find a document of dust collector in the depths of their (digital) archives.

• How to call a dll from another dll functions

  Hi, can someone please tell me some examples or instructions on how you go about calling functions from a dll from another dll including the IUR. The two DLLs were created with labwindows cvi.

  Thank you!

  Hi Sinnas,

  You mention that you use a UIR.  A DLL does not have a file UIR as part of it.

  DLL1

  Instead, when you build the DLL first, we'll call it DLL1, you create a header or the files that contain functions that you want to the client code to call.  When you build DLL1, you must export the file DLL1 function for his client to call code header.  Whatever the calling code is (a GUI or another DLL), you must include in the exported DLL1 project headers AND DLL1 .lib file generated when you generate it.

  DLL2

  DLL2 will contain in its project, the header file exported for DLL1, DLL1 .lib file - that gives it the feature in DLL1.  The code can then call any desired DLL1, but as DLL1, you should now have a header file that exports the functions of DLL2 desired HIS client code to call.  When you build DLL2, you create a .lib for THAT DLL file to include in the code of the final customer.

  GUI

  The final customer code will be a few GUI that you create to call DLL2 functions will have the UIR upper layer file.  It will include the exported DLL2 header file and the file .lib DLL2 in his project.  It can then call any function of DLL2.  It is the most clean way to have 2 dll working together.

  NOTE: You can create a GUI to test the lower level DLL1 functions before placing DLL2 in the system.  In fact, it's a good idea to do it - you want to make sure your lower level DLL1 code works properly before construction above it.

  Simple diagram

  Client code (calls to functions of the DLL2 header files) exported

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

  DLL2 (DLL1 function calls exported in header files)

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

  DLL1<--------------------  you="" can="" also="" create="" a="" gui="" that="" only="" calls="" dll1="" exported="" header="" files="" to="" test="" out="">

  A suggestion... I create my dll in debug mode and use them to test my code.  But I also build as static libraries.  When I do the final version of the system, I use static libraries.  They are built with the final executable and don't require additional files to install as do the dll.  When you install your system with DLLs, you must include all THE dll and they must be installed in the folder Windows/System32 of the target computer.

  I hope this helps...

• The DLL call fails when DLL uses a wide range

  I call a C++ dll in LabVIEW 32-bit on Windows 7. I kept getting error 1097 and finally understood it is because the dll uses two large paintings of 5 MB each. The tables are initialized in the constructor of an object, malloc is not used, or whatever it is. If I do the smaller berries, then everything works fine.

  The problem is not difficult to work around, now that I know what is the cause, but can someone tell me why a dll using a lot of memory would be a problem? I feel that 10 MB is really a lot of memory to use on modern computers.

  OK, you can test the appeal of the DLL in a Visual Studio test harness?

  In addition, in case you haven't seen another 'DLL error 1097' son type, here are a few. The cause of 1097 in your case can be illuminated by a multitude of courses of troubleshooting:

  Call dll error 1097

  Error code coming 1097 in DLL call

  error 1097 after the call dll function that allocates memory inside

  1097 error in the transition from table from C++ DLL for LabView (seems very relevant, although long)

  I know there are a lot of reading, but there is a good chance that the magic trick is in one of these threads already. We will ride on the shoulders of their work.

• TestStand do not call a Labview DLL copied to a new location.

  TestStand v4.2 & v8.6.1 LabVIEW: I have a problem with TestStand calling a Labview project DLL. It will call the DLL successfully if it points its record source (the directory where the DLL was built. However if the DLL is copied to the clients working directory and the appellant TestStand step points to the copied DLL, the problem occurs. The TestStand calls the DLL from the working directory of the client, but does not execute the DLL, simply set the status of the step to "Done" where he clearly didn't.

  The vi named in the DLL has correctly, all handles error clusters such that if there is an error in the vi running, the error would be forwarded to TestStand.

  Any ideas please?

  Update: the original problem was never solved, but another method was used successfully to generate an Excel results worksheet. This used controls Active-X to open a file, import a model, write the data, close the file, and then make the new file read-only. It now everything works fine.

• Call any thread DLLs the application crashes

  I have a built in 2015-labview application that acquires spectra of 6 spectrometers via an external dll. The dll triggers an event in labview when data is ready to be pulled from the spectrometers. Since this event, I am running a reentry no void / vi which contains a node function to retrieve the data, that are configured to run in any thread, as it gives a drastic improvement of performance as apposed to run in the UI thread.

  However this can slow down the application crash with a message from windows like the following journal:

  Name of the failing application: axiom 2.0.exe, version: 1.0.0.82, time stamp: 0x5581a6b7
  The failed module name: lvrt.dll, version: 15.0.0.4024, time stamp: 0x5581ac03
  Exception code: 0xc0000005
  Offset: 0x0000000000bec7c0
  ID of the process failed: 0x15c0
  Start time of application vulnerabilities: 0x01d11e6face9febd
  The failing application path: C:\Axiom 2.0\builds\Axiom 2.0\Axiom 2.0.exe
  Path of the failing module: C:\Program NIUninstaller Instruments\Shared\LabVIEW Run-Time\2015\lvrt.dll
  Report ID: 7d4ef3a8-8a91-11e5-94e9-90b11c894ef8

  I don't know if the dll is said to be thread safe or not. Also I do not understand how this causes a problem anyway since it is the only node that accesses the dll at the time, and each of the 6 spectrometers are interviewed in order?

  Is there anyway that I can still enjoy the benefits that the call of any thread dll provides without causing my application crash.

  An example of the increase in performance, it's that I can query the spectrometer from 6 to 70-80 Hz when configured to run in any thread, as opposed to a simple 10 Hz when the Run value in the UI thread.

  Thank you

  Looks like that the DLL is not thread-safe. If you do not run in the UI thread, there is no guarantee that the DLL will be always called from the same thread, even if you only call it in one no reentrante Subvi. By default, LabVIEW allocates multiple threads by the enforcement system, with the exception of the user interface. If the DLL stores certain information of one call to the other, this context can be lost when run in a different thread.

  Here's a thread that provides two possible solutions; a wrapper DLL is required, use the other the utility 'threadconfig' (or the corresponding INI file settings) to force a subsystem of a thread executing unique http://forums.ni.com/t5/LabVIEW/Force-DLLs-to-tun-in-the-same-thread-expect-the-UI-Thread/td-p/11438...

  Another option would be to put the call to the DLL in a timed loop that runs constantly, and you can use a queue or the notifier to pass data to. A timed loop runs in a single dedicated thread, so I think it will work.

• What is the banner that comes down from the top of good windows support for?

  Whenever I scroll down to read a page on the Apple forums, a banner comes down from the top of the window. The banner has the question on what started the thread.

  I don't see any use it serves unless you have a VERY short attention span. It's boring and covers a text (reduces the size of the window), so it's worse then 'not useful' - it is harmful.

  Yes, I see the 'X' which I can click to close the banner - but is it possible that I can turn off this feature altogether?

  Turn it off, no.. Guests sometimes read the posts here and see if all goes well your comment.

• Adobe Reader Plugin not available in FF38.05 64 bit - how to get it?

  The Adobe Reader Plugin is simply not available in my 38.05 Firefox 64 bit - I can't download it from (tried) Adobe or anywhere else - how do I get the Plugin?

  Thank you

  That's the downside of trying to use any Firefox Win64 versions (including the 38.0.5b2 that you are testing) are the plugins must be 64-bit as 32-bit Plugins won't work.

• DLL from the Windows API (user32.dll) causes a fatal error

  Hello
  On installation, we using a touch screen. LabView software is running in full-screen. I need to deactivage my Panel before if the screen saver is to warn the user start anyting. I use user32.dll SystemParametersInfoA and it works well, except, if I left the software. "myexe a fin a mistake and should be closed" (something like that my XP is in french).

  I have no issues in debug mode, this error happens in exe mode.

  I use LV 8.6.1. Do you have any idea why?

  Thank you

  SPI = 114 = SPI_GETSCREENSAVERRUNNING

  If * value! = 0, screen saver, ON the other scresaver OFF

  Still have the fatal error of Windows.

  Thank you

  I noticed the node having a rather odd way of user32.dll on the initial load of the library call. You happen to have copied this DLL somewhere and SEO with full path to your VI?

  It is a very big NO-NO! User32.dll and several other Windows system dll weird for the system and are all bad behavioured if you try to load another copy elsewhere on the disk as the system directory. Just rename the user32.dll library only and let Windows choose the good DLL from the system directory.

  Another problem with specifying the full path to a copy of such a DLL, it of that LabVIEW you will think that you must have this built application-specific DLL and will include it in the build. However your user32.dll is almost 200% VERY incompatible to any other Windows system there, because of the Windows Service Pack version and upgrades of the correction of a bug, as well as different versions of Windows.

  Hello

  Calls unrequested telephone of this nature are almost always a common scam. Do not let them give any info, do not give access to your PC, not give them all the money and do not go to all the websites that they suggest. One moment.

  Please see:

  Microsoft issues never not solicited for phone calls of support or security.

  These types of callers can use completely fictitious names or bogusly claim to be of real companies other than Microsoft as well.

• dll from System 32 error code (0 x 300000030)

  dll from System 32 error code (0 x 300000030)

  First of all, if you have gone through your windows folder, you might be familiar with the name of the system32 folder. This is a very important issue and part of your operating system without which your system may not work at all. Some consider it as the brains of the operation because it contains many dll files in what is active and runing in every process of your system. As it is an important part of your operation, I want to tell you to keep away from this folder and never delete or change anything. It's all about your system 32 folder located in your windows folder. This has nothing to do with system32.dll.

  System32.dll is a Trojan called harnig. Harnig Trojan isn't part of your operating system and is a very harmful infected file that will give all your information navigation to advertisers and sponsors. It can also result in loss of data and information from your system. The developer of this Trojan must were smart by naming "system32" to confuse people because the experts always fear users to stay away from the system32 folder.

  Now that you know the difference, you do not necessarily have to deal with these problems by yourself. But if you have a missing dll file or a file that is corrupted in your system 32 folder, you can try some easy stuff for yourself. First of all, you can try the system restore to an earlier date which is a good way to fix many problems by taking your computer to the date of the last when your operating system have saved all of your settings. You can easily do this by restarting your computer. Once the computer stops and tries to start again you must press f8 until you see the black screen with options and then select 'safe mode' and choose the option to start windows system restore. If this does not work, you can try another way by the same procedure that is, restart your computer and press F8, but instead select "safe mode", select "Start using last good known Configuration".

  Now, all these things might or might not help you fix or replace your system32.dll files. But how can you be sure that there is a corrupt or a dll file missing in your system 32 folder? Because their could be a virus in your system 32 folder that is if other dll files. It could be something similar to the system32.dll file. You can easily solve the problem of virus system32.dll and another problem of dll with the help of a good registry cleaner that got all of the definitions and the dll files library.
