Error: Aufgerufener ist ungültig. [Error Code: -17502, System Level Exception.]

[Andreas Kuckhahn]

Hi!

Im trying to control an installed software package for a camera over an activeX-Server.

I have chosen a couple of methods and integrated it into the teststand sequence over the TestStand ActiveX Adapter. So far so good.

Now, there are a couple of methods, which work properly... but theres one problem:

My Problem: I got one method, which is unfortunatly responsible for reading out measurement data. I dont have to say that this is an essential function for me. This method doesnt work. 

I call the Method and give it some proper parameters. After that the following error occurs:

Error: Aufgerufener ist ungültig.
[Error Code: -17502, System Level Exception.] 

Its the German Version of TestStand. I guess it means that "the called one isnt valid, Error Code -17502 System Level Exception"

I have to admit that Im not really experienced in working with the activeX adapter.

I made a screenshot in the attachement below.

HELP!!!!!!!!!!!!!!!!!!!!!

Hi Andy,

What are the parameters for iGetStandardStatistic ?

There are three integer parameters to overgive to the method and 6 real-number parameters which are given back from the method. So the parameters aren't so complicated.

Furthermore I found out the following:

In the Problem described above I tried to call the method over the TestStand ActiveX Adapter.

Meanwhile I tried to create an LabView VI in which I overgive the ActiveX Reference and do the job over Invoke nodes... Surprise!Surprise! It worked.

So I found a solution for the problem, but I can't explain and I definitely dont know why it doesnt work with the ActiveX Adapter

What can be the problem?

Hi,

Maybe you have the wrong reference to your ActiveX Adapter step.

Maybe you can post a small example

Hi,

TS stores Numbers as double (8Bytes)

If you are using int, char or float TS will cast automatically

BUT if your Method is using a variant can not cast !

See this thread: http://forums.ni.com/ni/board/message?board.id=330&message.id=24860&query.id=1109895#M24860

Please post a screenshot of the ActiveX Module settings.
