it would not let me post this initially
below is the error message

I did change it as suggested and it started acting like one would expect .. in the end I changed the calling Thread so that I now can wait direct for the flag without using async calls at all - I feel a lot better about this approach - & but I did learn something :-)
Thanks !

Isn't that what i already had ? .. I must have missed something
-I'll give it a try and let you know

Another Method following the Wait_move

Problem is timing as the wait might be very short (5ms is what i see now)
I could use a simple loop with a delay in the main thread but that makes it unresponsive with short delays (using sleep)
I was hoping for a cleaner solution :-)

"doSomething" is just for me to cancel the move if something goes wrong

Georg Kohler 13-Feb-18 13:09pm View

Ismoving is modified by another thread that's handling the moving of the axis.
After commanding the axis there is a short delay before they actually start usually a few ms but if we never start the move the main thread is the only thing that can stop the process (by pushing the stop button on the GUI and canceling out of the wait loop)

We do like to pick up the change of the isMoving flag as fast as possible because the move might be super short (10 ms or so)

Async call seemed the right thing to do (if it worked)

I know it's not working because the next method is called before the wait task finished - even after reading trough hours of online pages I really don't understand how this actually works ..

Any ideas on how to accomplish this without blocking the main thread 
I'm open to any ideas

KDMuser_settings is defined in a module that's added by reference to the DLL (That way they are always the same) - but that probably still counts as two separate definitions ....
What's frustrating, is that it seems like the data is right there at you're finger tip (at least in the debugger)

Georg Kohler 25-Jul-13 10:26am View

I think you're right - I ended up with the same "conclusion" (not that I understand why or what's the actual reason behind it)
I realized it once I started using ByRef in the DLL sub
>Public Sub DLL_SUB(ByRef Par As Object)<
It ended up giving me a more detailed error Message saying Object [A] can not be copied into Object [B] because they don't have the same origin - with the full path to both structure definitions - both are identical as one is a copy by ref of the other ....
Anyway I gave up at that point ... the current solution of translating the structure into a string and back works just fine - all It needs now is a better way of creating the string in a loop to collect all items from the structure...(avoiding typos)
Thanks for looking into it for me :-)

Georg Kohler 24-Jul-13 1:22am View

You again ??? I'm getting confused - again ?? what's all this miles of talk about something that has nothing to do with my actual question ??
I really love this Blog and have been asking on it for 10 years ?? or for sure for a long long time .. but I really don't understand what all this "Political" talk is about.
OK I understand you know a lot lot more about programming then most of us do and I don't know the correct terms to be used so lets leave that aside...

I come here to get some advice on how to solve probably rather simple problems that I just don't understand ..

Now to the Question ... It's very very simple ...
I have data inside a structure that I need to copy over in one step to my DLL -It's that simple
I use Reflection (i hope that the correct term if not I'm really sorry) to load and communicate with my Dll.. now at the point where I try to convert the data back into a structure on the DLL side is where I get in trouble - The data is there (You can "see" it in the debugger) but it fails to convert the data back into my new structure.. That simple
Maybe I need to create a new sub that Instead of the Object is passing the Structure ?? Could it be that simple ?? for whatever reason I thought that when using Reflection the only data type allowed to be "transmitted" is an Object (again sorry for my bad programming English)
is that correct or that what I'm missing - I haven't tried that yet but I will in a bit

Maybe this helped solving some of the misunderstandings ? I sure hope so

Thanks

Georg

Sure enough - once I tested the code in a blank form it worked ....Therefore I assume you where correct in that another control grabbed the "message"
Thanks for you're help...

Obviously I'm on the wrong track as far as the usage of the message structure goes (Dave's answer make this pretty clear to me)

Georg Kohler 7-Jun-13 18:21pm View

OK that makes sense - I'll run some tests and see what happens

Thanks

Georg

Georg Kohler 7-Jun-13 16:56pm View

I'm confused - What advice ?
You told me not to disable moving /resizing - This has absolutely nothing to do with my question!
what Am I missing ?

Georg Kohler 7-Jun-13 16:48pm View

Not sure why we argue about this..
Do you have anything to say about the actual Question I asked ?

Georg Kohler 7-Jun-13 15:51pm View

Actually your wrong .. working on an industrial solution most companies don't allow there Operators to play around with the forms ..
Also if you read the question, the removing /resizing is not my "problem" that's working perfect
- I'm wondering if I can actually trap a keydown event like this - it sure looks like you could - it's just "not working"

Georg Kohler 4-Jun-13 18:19pm View

Ok that makes sense ...

Georg Kohler 4-Jun-13 18:01pm View

So what you're saying, is that if the code indside the [userForm.someMethode()] task a long time, the UI thread will wait until it's process ?

Maybe I should to explain a bit more about my specific situation

I have a separate thread that reads axis positions(up to 6 axis) from a motion controller at a given interval( programmable but usually 100ms-200ms)
now I need to pass the Pos values to my DLL (if it's loaded)
I'm trying to determine, if I can safely do this without missing my readout "beat" of 100ms
Obviously I was wondering If it would make sense, to pass tasks in the DLL to a separate thread

Georg Kohler 24-Oct-12 12:51pm View

I believe it's related to a thread that I constantly stop and restart - actually I ended up Killing it at times with the abort command ...(not what you should be doing ... I know :-) ... but somehow that was the only way I was able to make it work "properly" until now ....

Georg Kohler 23-Oct-12 23:40pm View

I'm actually running in in the debugger ..- when the exception occurs some line get's highlighted (light green ..) but the debugger always highlights a different line ...with now further indication of what caused the issue ???

Georg Kohler 19-Jan-12 1:13am View

I had the feling it won't be that easy - I think i get the idea ...
I'll work on it tommorrow
you mentione quote : "and they are, again, are stored in some container"
Question - any idea how to locate this "container" - is it somehow "related" to the base class (that's what i remember , that there is a way to get a list of all instances of a particular class ....) But I might be wrong :-)

Georg Kohler 21-Dec-11 20:19pm View

Darn! I wish you would have posetd that 5 min ago :-) - I knew there was an easy way of doing this ....
just for everybodys entertainment - here is what I ended up doing ....

I changed the controls Tab Order to 0 in the VB / then by selecting tab order in the form I could actually locate the component on the form....(hidden under then main menue of course ).. changing the dock property for and back on the mnneubar eventually showed the component again ..

Thanks Anyway

I "love" you guys

Actually I just realized that It's not throwing an exeption at that point
It just reads out Nothing ( As nothing has been assigned) The exeption happend when I tried to compare it to a Type.. (sloppy me ..sorry)
Do you have any ideas what to use to read out the Type of the variable ?? (I've tried typof and son on and so on) TypeName just seemed the logical thing to use - but it looks like it won't work for Structures??

Georg Kohler 13-Sep-11 3:15am View

Correct -It's just a typo
I think I also have to rework the question a bit ...
The main thing is not for the Structure to work - The question is why I can not read out the Variable type befor I assigned anything to it ...
It seems once I assigne a value to the variable it works ...
As I'm loading Config values I would like to know forhand what Type can be accepted by the variable.

Georg Kohler 11-Jun-10 18:08pm View

THIS WORKED !!!!!!!!
THANKS :-)
