Invoke Remotely Failed : Object Identification and Technologies

[DanielS]

I've got this exception:

Exception: Ranorex.ActionFailedException: Action 'invokeremotely' failed on element '{Unknown:dawnGridControl}'. ---> System.Reflection.TargetInvocationException: Ein Aufrufziel hat einen Ausnahmefehler verursacht. ---> System.IO.FileNotFoundException: Die Datei oder Assembly "UITestApp.Interface, Version=1.0.4149.34227, Culture=neutral, PublicKeyToken=null" oder eine Abhängigkeit davon wurde nicht gefunden. Das System kann die angegebene Datei nicht finden.
Dateiname: "UITestApp.Interface, Version=1.0.4149.34227, Culture=neutral, PublicKeyToken=null"

What can i do? I'm using Ranorex 3.0.

now i changed to .Net 4.0 and i don't know wheter this problem still exists or not, if i know it i will post it here.

[DanielS]

Okay, the problems before are now solved, but i still have got this one, but with an new message:
*** Exception: Ranorex.ActionFailedException: Action 'invokeremotely' failed on element '{Unknown:dawnGridControlTaskfields}'. ---> System.Runtime.Remoting.RemotingException: Fehler beim Lesen von einem IPC-Port: Die Pipe wurde beendet.
What could be the Problem?
Best regards

update:
I've testet the same again and got this errormessage:
*** Exception: Ranorex.ActionFailedException: Action 'invokeremotely' failed on element '{Unknown:dawnGridControlTaskfields}'. ---> System.Reflection.TargetInvocationException: Ein Aufrufziel hat einen Ausnahmefehler verursacht. ---> System.IO.FileNotFoundException: Die Datei oder Assembly "UITestApp.Interface, Version=1.0.4155.20594, Culture=neutral, PublicKeyToken=null" oder eine Abhängigkeit davon wurde nicht gefunden.

Hi,

you are working with .Net 4.0 have you mentioned the that you have to create a config file?
See how it works in reason#5: http://www.ranorex.com/support/user-guide-20/technology-instrumentation/general-troubleshooting.html
If this won´t solve the problem can you provide us more information about your application and the actions that which leads to this problem?

[DanielS]

yes, i have created the config file. Without the config file it didn't work correctly ( the paths were not found).
Which information do you need? The Code which leeds to the error is:

Code: Select all

      override public string GetColumnCaptionByFieldName(string fieldName)
      {
         return (string)grid.InvokeRemotely(IR_GetColumnCaptionByFieldName, fieldName);
      }


grid has the type:
Ranorex.Control;

Best regards

[DanielS]

update: one important information could be that it's an Dev Express Control.

I'm using Win7 64 Bit and the program is 64 bit, too. While browsing in the Spy at this item i got two times an error, that the Ranorex Bridge failed, but i couldn't reproduce this error.

Hi,

According to your snapshot, Ranorex is able to recognize the controls.
Therefore I have following question
Why do you use the invoke remotely? Is there a control which isn't recognized by Ranorex and it is not included in the snapshot?
Please check the Event Manager of Windows, maybe we get more information of this log.

If it's no big deal, could you send or post us a sample application with the same behavior?

Thanks in advance.

Thank you for your answer,

Here is a code example:

invokeRemotely.rar

(328.2 KiB) Downloaded 16 times

Invoke remotely is used many times in my program, so it would be nice if don't have to rewrite the whole thing. The control shows a table with the results of a few entrys, and i have to check those results. The code is from my antecessor, so i don't know wheter it's possible to recode all without invoke Remotely.
Best regards,
Daniel

okay, now it's become very strange. The testSolution works now. But the first two times it did not work, and i changed nothing. This is the exception which was thrown:

In my main solution it's exactly the same code, and there it doesn't work.
Best regards,

[DanielS]

Now i've tested it with more InvokeRemotely functions, with the same code as in the main testAutomation, and in the testSolution it works, in the main solution it doesn't. How could that be?
This is the new Testsolution with one more InvokeRemotely function:

invokeRemotely2.rar

Hi,

Is there an AntiVirus or Firewall running on the computer where your InvokeRemotely call fails?
If yes, please deactivate this applications and retry it.
Regarding to your solution, is it possible to post us the corresponding application too?

Peter

[DanielS]

I deactivated AntiVirus, but without success, it still doesn't work. It's not possible to deactivate the firewall. Unfortunately i am not allowed to give someone the application.
How could it be, that two Ranorex Solutions with the same code work differently? What does the Error with the "Pipe"(Fehler beim Lesen von einem IPC-Port: Die Pipe wurde beendet.) mean?
Best regards,
Daniel
