Error property
recently, I try to communicate between PC and NEC based on modbus Protocol.
using the engineer NOR, I started using the forums.and modbus library when I run programs, visa resource out.and the following program error property not worked as it was supposed to happen.
as a newbie, I'm confused.and that all advice is appreciated.
Thank you very much.
PS: my program is as follows.
Hello
OK, now you know if your connection is OK.
Try the attached programme with the data on the block diagram.
You can use loop control to make sure that your physical connection is OK.
If it works as your ModBus communications program should also work.

Error property in parallel loops node
Hi all
I run two screws under SP1 LabVIEW2014 at the same time and each of them contains a loop to do something. In this case a VI loop reading a control channel via the property node and the other VI makes a loop showing an empty IMAQ Image. After a few iterations of the loop, the property node read the string value throws an error that I do not understand. The error occurs again and again.
If anyone can reproduce this behavior and/or knows the question on this?

Script error: property not valid value operation
(in FormCalc)
I have a form with multiple pages. The first two are a graph and the other 8 diagrams. Diagrams have fields of number to the entry measures taken from an inspection process. The graphic form I have a button to fill in the chart with information from diagrams.
The click event of the button first retrieves the information from the diagrams and transfer them to the chart. He is then supposed to change the font color depending on whether the readings are within limits (black for good, red for the worse).
However, when I go in the preview PDF tab, enter test data in diagrams and click populate, I get an error that I don't know how to fix. I was not able to find something on the Internet about it.
Any help would be greatly appreciated. Here's what's on the screen of the error:
Script failed (language formcalc; context is)
XFA [0] form [0] .topmostSubform [0]. LHChart [0]. Button1 [0])
script =...
Error: The property not valid value operation; Police is not a default property
I found the solution to my problem.
I had the code in the target fields as well as the button trying to change color of font, based on imported figures. I deleted the code in the target areas and leave the code in the button field and everything worked right.
Thanks again for everyone's help.

I try to install Oracle JDeveloper 12 c on Windows 7, but I get the error 'Property CMD' not found in autorun.inf, when I run the file directly.
If I run Oracle installer (as an administrator), I get the file "corrupted", but I think it is misleading.
Google search, this seems to always point to that here where it says
Previously, I had a compatibility issue when installing Oracle Developer (forms, Designer, reports and JDeveloper10g), I corrected as saying that must be run on Windows XP SP2, and that did the trick. But I don't see anything about compatibility via the google search for this problem.
When the exe file is run some tests pre - req gets run as 64-bit JVM and Swap space. The other machine may not have the pre - req.

Right direct API - passing the error code
Hello
I'm trying to implement connection API in our application of DPS. I can see that there is a possibility to provide an error code in the action of SignInWithCredentials.
Results of the error:
HTTP 401 Unauthorized
Body:
< result httpResponseCode = error code "401" = "" / >
How to read this error on the side of the app code (in the action of the connection of adobeDPS.authenticationService.login (username.val (), password.val ()) ;)?)
It will be available in the field of the error of this transaction?
Or should I get another way?
I have need of this error code to display revelant message to the user that din't succeed to connect.Kind regards
PiotrThis API call returns a UserSignInTransaction. Once the fires of completedSignal you can watch the error property to get the error information.

Strange property undefined object
I created a clip and exported if ACE, naming the class "Tank." The clip has a couple of labels of image with a few photos inside on each label.
The SWF file opens, it gets added dynamically to the scene as follows:
var charMC:MovieClip = new Char();
addChild (charMC);
charMC.x = 164;
charMC.y = 624;It works fine without error.
However, further down I have a function that will call this clip and move it into a different image. As follows:
function someFunction (): void
{
a few things
charMC.gotoAndPlay ("start");
}
This does not work, and I get the error "Property not set of charMC access."
Note This function has not yet been called yet, I get the error when compile the swf file. It makes no sense to me. What I am doing wrong? It seems that the variable/object is in scope, as it has already been set and even added to the scene.
Where are you declaring and adding the clip?
If var charMC:MovieClip = new Char();
is inside a function, then it is not available everywhere, but inside this function.

Property not found (member) on a sprite
Hey, I have the following script against a sprite:
property pMyMemberCount, pMyMember, MySpriteNumon beginSprite me
MySpriteNum = me.spriteNum
pMyMemberCount = 1
end
endon exitframe me
pMyMemberCount = (pMyMemberCount mod 2) + 1
pMyMember = "GravPush" & pMyMemberCountMySpriteNum.member = member (pMyMember)
endWhich is supposed to change a sprite member between 2 images in the cast that I named 'GravPush1' and 'GravPush2 '.
Whenever I'm going to make the movie, I get an error:
Script error: property not found
MySpriteNum.member = member (pMyMember)
#member
Does anyone know how to fix this? Thank you
I think you want that last line to be:
Sprite (MySpriteNum) .member = member (pMyMember)

Hello
I have a cast member of text on screen called 'round of text '. I placed it on the stage. When the user proceeds to various things, the text in the cast member is updated. I am looking for a way to determine the height of the sprite on stage as the text changes.
I tried .height sprite (25) and it always returns the height of the sprite sprite was when it was added.
I tried member("cycle_text").lineCount, but get an error "property not found".
I'm sure I'm missing something obvious, but he can not see. Does anyone have any suggestions?
Thank you
PatchTry this:
Member("cycle Text"). Line.Count
The property 'lineCount' is only available for the members of #field, not #text
members. -
The API XNET-CAN allows to hardware configuration such that a call to read the framework/signal does not return until the message is received (no need to query the buffer, call to the function is as an event... function returns when a message is received) or if a time-out occurs). I don't really want to query for data, unless I absolutely have to. My plan is to have parallel code to wait for a specific message to receive and respond (should be very fast!) whil a different loop receives all other executives.
A time-out of the reading function call would work pretty good, but it doesn't seem to work (see extracts attached). The value of timeout only seems to work (no error property) is a value of 0 seconds.
Thank you

Problems installing JDeveloper
Hello! I'm launching jdev_suite_121300_win64.exe, but I get an error: 'property not found in autorun.inf CMD'.
After that, I decided to install manually.

I have some difficulty to get a button to load and unload a swf file that is incoming.
http://www.scottberks.com/clientwork/Flash/Flash.zip
I use CS6.
Any help would be REALLY appreciated.
Few things quickly... You use the right loadScene() in a frame script that is generally very well but just for security, it is often advisable to wait to enter a frame to trigger your first script, especially when accessing the scene.
for example
addEventListener (Event.ENTER_FRAME, onEF);
function onEF(e:Event):void {}
removeEventListener (Event.ENTER_FRAME, onEF);
stage is certainly ready here, run the function
loadScene();
}
Apart from that, you're not any verification error on request of the shipper. You can find many examples of audit for all kinds of charger page load errors:
Charger - Adobe ActionScript® 3 (AS3) QAnywhere
Specifically keep in mind add you listeners to the error property of the Loader object myLoader .contentLoaderInfo:
After that, your code of backButtonClick() function button performs a new URLRequest, asking the charger 'singleLoader' you did to load and then execute addChild (myLoader) instead of the "singleLoader". If your intention is literally to recharge it, you just need to use 'phone' once again rather than 'singleLoader '.

reset the position of the sprites
Hello world
I'm unable to a simple matching game.
Basically, I want to create a code that will ensure that each sprite is at a location given at the beginning of each game. Currently these sprites are not in their correct location when the game is re-played.
The following code displays the error "Script error: property not found. Can someone tell me what is wrong with him?
on prepareFrame me
-put the sprites where they are supposed to be
resetpOrigLoc()
end
on resetpOrigLoc
Member("Kngwarria").loc = point (73, 111)
Member("Kamaarra").loc = point (151, 69)
Member("Ngala").loc = point (220,24)
Member("Pungarta").loc = point (307,68)
Member("Pilthaarra").loc = point (375,25)
Member("Purrula").loc = point (445,68)
Member("Mpitjaana").loc = point (549,112)
end
Thank you, else
As James suggested:
However, you call this Manager each time Manager refreshes the screen, so the sprites will be constantly placed in these positions, even if the user tries to move them.
I suspect that you want 'resetpOrigLoc()' Manager in a beginSprite handler, instead of prepareFrame.
