COM objects hierarchy

• Using ThinAPP COM objects exhibition

  Hello

  I try to get a working example of a COM object exposed in ThinAPP.

  I wrote a small ActiveX DLL using .NET and I'm trying to expose through ThinAPP so it can be used as an object embedded in a Web page.

  Apparently I am still missing some points, for example:

  • What kind of object use? a DLL? an EXE file?

  • Is it possible to incorporate a DLL in the registry to guests so it can be used regardless of membership. Package EXE I created with ThinAPP?

  • I would have the packed. EXE running at any time to access this object?

  I'd appreciate any help or comment.

  Thanks in advance,

  -Dror

  ThinApp works at the level of the .exe, not at the level of the .dll. This means that you can make out of process (.exe) COM objects available for applications that run outside of the virtual environment (applications running in the virtual environment have access to inproc COM objects contained in the package).

  You can expose your .exe COM object by including an ObjectTypes line in Package.ini and then save it with the package on the system using Thinreg. This will create the COM registry entries in the system registry. The COM libraries on the system will then take care of launch the ThinApp package when another application calls CoCreateInstance on either of the ObjectTypes.

• Occasional exception error occurs during the execution of a COM object.

  I am running Coldfusion 8 and search of addresses through the Mailroom Satori software database architect.
  
  6 times out of 10 the address returned, but other attempts to achieve what follows:
  
  An exception occurred when executing a COM method
  
  The cause of this exception was: AutomationException: 0 x 80040400 - Unknown exception in SearchAddress. in MRTKUKLib.MRTKUKPostCode.1
  
  I reinstalled the software architect and ensured that the COM objects are registered. I am puzzled, how it can work frequently, but then sometimes fail. I'm running a high volume website, this could be a problem?

  Possible.

  It could also be choking on something in the data that you send to the COM object. I would surround the code that calls the COM object with an error handler that automatically sends you the address information that you send to the mailroom architect when he chokes. See if you notice any model. Could be a number sign in the address or an apostrophe wandering? or maybe even a few non-ASCII text?

• Errors in creating Java Stub for the COM object.

  Any help is appreciated.

  I have not solved this problem. I worked around it by using an ASP.NET web service to expose the .NET assembly.

• Moveable object hierarchy

  Hello
  I wonder can you help me?
  I have 4 items on the screen I want users to drag and drop as see fit them. The problem is some objects are higher in the hierarchy than others, and when low priority items are driven near the highest priority that they get stuck. It's very annoying. How can I make the moved object always become more important?
  
  Thank you!

• Determine the hierarchy of objects based on the dependency.

  Hi all
  
  All packages in the database has invalidated due to a problem. You need to find the object hierarchy in oracle.
  
  Is it possible that I can the oracle object I the hierarchically based on the dependency?
  
  Is there a metadata table that stores this information?
  
  Example: Say, there are 10 packages. Package 1 depends on package 2 and 3-based package 2 and so on... and say package 10 is not dependent on.
  
  I need the list packages in the way below.
  
  Package of 10
  Package9

  Please let me know if you need any details.
  
  Thanks and greetings

  Something like this:

  select * from dba_dependencies where 1=1 and name ='PKGABC' and type = 'PACKAGE BODY'
  union all
  select * from dba_dependencies where 1=1 and referenced_name ='PKGABC' and type = 'PACKAGE BODY'

• Can't print Photosmart C5280. Error "object GPCore COM has stopped working and was closed".

  I have problems printing my Photosmart C5280 All-in-one on my desktop of Windows Vista 32-bit. I felt for a few years and have only recently met this issue. A few months ago, I set up a home network so I could print from my Toshiba laptop. The printer is connected to the computer via a USB cable and the laptop is connected via a Bigpond Modem/Router which is connected to the desktop via an ethernet cable. More recently, I have also configured for my son to be able to print from his HP laptop. Initially, we were able to print from any computer. The two paltops are running Windows 7 64 bit. However, in recent weeks, we noticed that we were no longer able to print from a laptop, and a few days ago, I was unable to print from the office. When I try to print from the office, the print job seems to go to the print queue, but is then removed from the queue. I then get an error message

  "GPCore COM object has stopped working and was closed".

  
  

  This applies to all applications even the test print. I just went through the steps on the HP site, including downloading and execution of printing HP troubleshooting and doctor Scan and uninstall then reinstall the printer. I'm a bit of a novice at the side Computer Hardware and wonder if there is anyone out there who has had a similar problem and found a solution. Any thoughts would be appreciated.

  Hello MikeF48,

  Sometimes to do a simple uninstallation / reinstallation is not do the trick, and we try to remove all the software from the computer completely. Most of the drivers available at HP have a scrubber utility that removes all traces of the software on the computer and allows you to reinstall the software fresh. We should start there and see if that gets us running.

  I recommend you to do all this on the Vista machine. Once we have a working computer we can then pass from there to other laptops.

  Here are the instructions to use the tool of the scrubber. There are two sets of instructions, one for if you have installed the drivers from the HP website or if you have installed the drivers from the CD that came with your printer. Follow the instructions for your installation accordingly.

  Of the Original installation CD:
  1. Insert the CD in the drive and then cancel Setup
  2. open my computer and click right then on the CD from the drive and select open
  3 open the Util folder
  4 open the CCC folder
  5. If you have an HP computer, run the L3uninstall.bat. If you have a computer not HP, run the L4uninstall.bat
  6. once the uninstall is complete, restart the computer
  7 run the Accessories\ System Tools Disk Cleanup
  8. download and install the latest version of Adobe flash player
  http://get.Adobe.com/flashplayer/
  9 download drivers and full software features
  Software & Driver Downloads - HP Photosmart C5280 All-in-One Printer - Vista
  10. run the download to reinstall the printer
  
  If the software has been downloaded and extracted to your system:
  1. type % temp % in the field of race
  2. Locate and open the folder starting with 7z (example: 7zS2356)
  3 open the Util folder
  4 open the CCC folder
  5. If you have an HP computer, run the L3uninstall.bat. If you have a computer not HP, run the L4uninstall.bat
  6. once the uninstall is complete, restart the computer
  7 run the Accessories\ System Tools Disk Cleanup
  8. download and install the latest version of Adobe flash player
  http://get.Adobe.com/flashplayer/
  9 download drivers and full software features
  Software & Driver Downloads - HP Photosmart C5280 All-in-One Printer - Vista
  10. run the download to reinstall the printer

  After having uninstalled the software and did a reinstall of fees. Let me know if the problem is still the Outlander.

• DLLSurrogate on Server 2008 STANDARD (NOT R2) does not not a COM 32 bits of the 64-bit VBS script object.

  I can't get DLLSurrogate on Server 2008 STANDARD (NOT R2) to load a 32-bit to 64-bit VBS script COM object.

  Yes, I tried the Wow6432Node "redirects" and THAT runs on Server 2008 R2, but NOT under the STANDARD!

  The PROBLEM is that the VBS Script is called from SCOM (which is 64 bit [SCOM 32-bit on a 64 bit OS is "unsupported"]), who, in turn, must run the application Code to 32-bit (return MOMScriptAPI.PropertyBag [64-bit, in this case])!

  Under Server 2008 R2, the technique to create entries of DLLSurrogate under HKCR\Wow6432Node...  Works PERFECTLY, the PROBLEM, this is the verion of the 32-bit code we (still) lack in Production does not support running on R2.

  I can't seem to find a way (once again, on Server 2008 R2 (x 64)) interact in a 64-bit environment / 32-bit mixed!

  Anyone have this working?

• Call COM components as a service Windows 7 (NOT A WEB SERVICE!) via LabVIEW

  First of all, what I'm trying to do is completely new terrority for me and I've looked everywhere, impossible to find a solution. I have reviewed the following resources and tried to get out but nothing helps:

  [1] ActiveX and LabVIEW
  http://www.NI.com/white-paper/2983/en

  [2] ActiveX and COM - part I
  http://www.NI.com/white-paper/2981/en

  [3] tutorial: Configure the node of the function of the library Call to call a Simple DLL
  https://decibel.NI.com/content/docs/doc-9069

  My problem is that I got a COM which was installed to run as a Windows 7 service, always running in the background (service.msc). So far, it seems only to be an intuition that you shoul dbe able to use:

  (A) ActiveX in LabVIEW to call the COM object by name or the .dll file.

  (B) call the .dll file of the service using the library function node call

  I see the COM running as a service if I (service.msc). I see also two .dll files associated with this service (they have the same base name as the service running). Let's say the service is called "TestService" then the other two .dll are called "TestServicePK.dll" and "TestServiceXY.dll." In test ActiveX and node library function call, I tried to call the two .dll files. When I tried the ActiveX method I get "the selected file is not a .NET, type library or executable automation assembly."

  Also COM binaries were made in C++, but if I understand well there should not be a problem at least for the library call feature.

  This seems to be a case of corner.

  Actually COM! = ActiveX!

  COM uses ActiveX to implements its objects and also to instantiate and control their but COM is simply a binary model of the API and some functions to control the instantiation and the lifecycle of objects COM, nothing else. The only way to access COM objects correctly (when no ActiveX type library is provided) is to have a C (++) compiler that can analyze the header files according to interface with the interface object methods. All ActiveX controls use COM to implement the interface calling of their objects, but also adds a type library in the DLL and a few other niceties such as the properties of the object. This type library describes how to match the properties and methods of the ActiveX for real virtual table COM interface pointers.

  LabVIEW lists this type library in order to be able to interface to the COM, Active X objects interface. A pure COM library is missing all these subtleties. If LabVIEW would be favourable to a COM interface node, its configuration should allow the configuration of all the things that describes the type library. This configuration would require a lot of manual configuration details, similar to what the library node call, only a magnitude more complex. If this is not really an option.

  If your server COM DLL does not an ActiveX type library interface, the only way to access it in LabVIEW must obtain such a type library as an external interface (not possible for all COM components) or to wrap the COM DLL server by a traditional DLL, which translates the methods standard COM exported C functions then that may be called by the node library call.

  Creating a library of types from a single COM DLL is more or less unfeasable. You should at least have the original IDL file that was used to create the interface com write a C (++) wrapper for your object COM is very probably the most practical approach, but will require some good C programming knowledge as well as experience handling COM objects in C code.

• How to create the SyncManager CSharp object

  Greetings!

  I am tryint to send a means to a sequence of testStand from a DLL of Chernobyl... it seems that I have to use the SyncManager, but I can't understand where the syncmanager object is defined:

  XXX foo = seqContext.Engine.GetSyncManager ("myNotification");

  The problem is that I can't determine what should be the type "xxx".  I would have thought it would be a "SyncManager", but this doesn't seem to be a valid type.

  I'm referencing: NationalInstruments.TestStand.Interop.API and NationalInstruments.TestStand.Interop.UI

  What is the correct type?

  Thank you

  Tom M.

  Hi Tom,

  you add the TSSyncLib.dll as a COM object to your c# project

  Then it should work

  Hello

  I don't know if this is the area to ask this question. If it is not please let me know where I need this post.

  We have an application that installs on desktop to users who access a COM object + in the same machine auto. This COM object + access to another COM object + on a server, which is used to send emails. The two COM + are ours.

  A few days before our application lying around and it is not able to send emails. This problem is solved after restarting server.

  We checked the event logs in the users machine and the server but unable to find problems.

  Please let us know where we need to check, to find the cause of this problem?

• How to use COM DLL in LabWindows

  Hello

  I have a COM .dll file that looks like this when opened with dll export viewer:

  

  I would like to use the Get4AxisPos function in LabWindows.

  I realized that, as I only have the .dll file, the only way to call these functions are the LoadLibrary() and GetProcAddress() functions.

  My problem is that the function Get4AxisPos is not of type exported function but COM method, so I don't know how to use it in my project LabWindows!

  My questions are: is - this will use this dll in Labwindows? If yes how?

  Thank you

  Use tools | Create the ActiveX controller... CVI to generate a range of function that contains the code of the interface that allows you to manipulate COM objects in the DLL. Search Help for "ActiveX controller Assistant" more information on this installation.

• COM Surrogate (dllhost.exe) and question of loading folder

  Hi all

  There are 2 problems that I think are related, but I could be wrong:

  1. Some files are loading very slowly (or even does not at all). The framework itself is displayed instantly, but the content is not and the Green loading bar in the address bar is.
  2. Surrogate COM (dllhost.exe) is always eat up to 13% of the CPU (so I guess that 100% of a wire with a processor of threads 4 cores x 2 I).

  Running on Windows 7 x 64, all updates installed.

  I saw a bunch of related issues here but with apparently different sources. I tried already to:

  • Run the System File Checker: no problem.
  • Run Microsoft Safety scanner: no problem.
  • Check the system drive to find errors: no problems.
  • Run Microsoft Fixit performance: some software/services launches at startup, but don't see any suspicious things.

  Any suggestions?

  Thank you very much!

  Niranjan salvation!

  And thank you for your fast answer :)

  First of all, my problem is (partly) solved! But not exactly by doing what you suggested.

  Pretty good for me and for the moment in any case. :)

  Let me explain:

  As you suggest, I created a new user account, restarted the computer and connected with the new account. And Yes, magic, the problem did not appear.

  So I happily spent at step 2 of your recommendation that would transfer all my data to this new account to use as the master account.

  But while I was browsing windows to copy my data the problem reappeared.

  So after some research and a few tests, I realized that the question was in fact a video file on my desktop. An .asf file to COM surrogate could not create a thumbnail *. Perhaps because of a mistake or missing codec? In any case, deleting, I solved the problem.

  Hope this feedback will help others and I hope that will come a software fix.

  Best regards

  * The COM Surrogate is a fancy name for sacrificial processes for a COM object that is running outside the process which has asked. Explorer uses the COM Surrogate during extraction of thumbnails, for example. If you go to a folder with thumbnails enabled, Explorer will trigger a COM Surrogate and use it to calculate the thumbnails for documents in the folder. It does because Explorer has learned not to trust miniature extractors; they have a poor track record of stability.

• Recovery of the class factory COM for component with CLSID {3CE74DE4-53D3-4D74-8B83-431B3828BA53} failed due to the following error: 80040154

  Recovery of the class factory COM for component with CLSID {3CE74DE4-53D3-4D74-8B83-431B3828BA53} failed due to the following error: 80040154

  Hello

  1. you remember to make changes to the computer before this problem?

  2 are you able to open files from other Adobe programs?

  Follow these methods.

  Method 1: The problem is that by default, when the PDF program is used as a COM object, then it cannot be activated by the following accounts:

  (a) a Director

  (b) system

  (c) interactive

  How to solve this problem is to change the DCOM settings for the Application'S object.

  Configure DCOM

  a. click Start, type run in the start search field.

  b. type DCOMCNFG , and then press OK. (This will load the "Component Services")

  c. navigate to Component Services, click computers, my computer, DCOM Config application PDF.

  d. right-click and select Properties.

  e. Select the Security tab.

  f. in "Launch and activate permissions" select personalise and press change.

  g. press the Add button to select the "Network Service" account

  f. click on the OK button, and then test your application, it should work fine now.

  Method 2: If this does not help, you can uninstall and reinstall Adobe reader software and check.
