How to use "Value signaling" for boolean-latch button?
Hello,
i hava an event-structure with a boolean-button on it (Mechanical Action: Latch when pressed).
For this button i have an event "Value Change" - works all fine.
Now i want to execute this event from an other event by sending a True into the Property-Node "ValueChangeSignaling" of this button.
But now labview tells me:
When a Boolean control has a latch mechanical
action, you cannot use the Value property to read or write its
value.
What can i do now to execute the existing event of the button?
Thanks
The reason the latched boolean cannot be set via Value property is described here:
http://digital.ni.com/public.nsf/allkb/0774F8F0498017B886256F080066E2E3
A little further info from the help:
Note You cannot use any latch action for objects with a local variable. The first local variable to read a Boolean control with latch action resets its value to the default. If you configure your Boolean value with a latching mechanical action, the Value Property and the Value (Signaling) Property always return an error. Due to race conditions that can occur when you have a Boolean value with latching mechanical action, you cannot programmatically read Boolean values that are set with a latching mechanical action.
So your options are to either change the change mechanical action to switched, and programmatically set it back to False inside your event case, or use another method to fire your event (as previouosly mentioned, consider user events).

How to use Value Mappings for simple translations?
Hello,
I want to use Value Mappings for simple translations in mappings, e.g. from IDoc to Inhouse structures.
For example unit of quantity:
IDOC --> INHOUSE
PCE P
ABC A
How can I use Value Mapping for this? What should be used as Agency, what should be used for Scheme? What about groups? I tried the following: I created a new Value Mapping in Integration Directory:
- Source Agency: DELVRY05
- Source Scheme: MENEE (IDoc field name)
- Target Acency: INHOUSE_DESADV (Name of structure)
- Target scheme: UNIT (Name of field)
Then, in the table, I added several lines for translating PCE to P and ABC to A and so on. But I have to define a group name for each line. I used INHOUSE. But than I get one INHOUSE group for each line.
This seems very complicated for simple translations from A to B. I don't want to use FixValue in Message mappings.
Any help appreciated.
Thanks,
ChristophHello,
@pavan kumar: Thanks, but I know all Blogs about Value Mappings. That does not help me. And I refer to PI 7.1.
Lets get it very simple: I want to have exactly the same functionality of "FixValues" as ValueMappings. In 7.1, I need to define a Group for every row / line in the conversion table (e.g. for units of measurement conversion between IDoc and FlatFile). That does not make sense for me, as the Group is always the same, e.g. "Unit of measurement". So I will get dozens of same groups called "Unit of measurement".
I don't really understand the concept of Groups. Maybe this is just not appropiate for my intenses? Maybe the Group has to be defined as one specific value of Unit of measurement, e.g. "pieces"?

How to use startscan signal for triggering for E-series DAQ
Hi, I want to collect the engine cylinder pressure data with a PXI-6070E DAQ card and BEI Encoder. I want to use the TDC signal as trig1, and crank angle signal as startscan for triggering. Could anybody give me an example or suggestions about doing this in labview. I cannot find any example that uses startscan signal for trigging. Thanks.
There is an example VI that is installed with LabVIEW. It is called "Cont Acq&Graph ExtScanClk D-Trig.vi" and it is located in the following LLB.
\Examples\DAQ\anlogin\anlogin.llb
Your project aligns very closely with a past project of mine. If you require professional expert assistance, feel free to call on us.

How to use same actions for differ pop-up
Hi gurus,
I am using 2 popup in a view.same popup's having same buttons 'Yes', 'No'.when i use 1st one i have to create an action for that Yes button where i put my code for that particular Action.
But when i used 2nd one the action define for that is not acceptable with differ name.it takes only standard one.
Now my Query is : How to use same actions for differ pop-up buttons with in a similar view?Where i put my code.
Plz sugges me.
<b>Points will be sured.</b>
Sanket sethiHi,
Take one integer value attribute in the context of view
when you r performing action on POP1 set it's value to 1
when you r performing action on POP2 set it's value to 2
create one method which receives integer argument, say diaplay(int a)
In the action call display(wdContext.currentContextElement().get<intvariable>()) by passing the value in the context attribute
in display() method, Check the value of integer variable..
if it is 1 then perform action related to POP1
if it is 2 then perform action related to POP2

How to use time capsule for wireless back-up but not internet?
Hello,
I have a tower and recently a laptop at work. The tower is connected to our local network with an ethernet cable and the laptop with wireless. So, the internet connection is fine for both.
I was hoping to use my time capsule to do time machine backups on my laptop. Do you have any advice on how to configure this? I do not want to use the time capsule to extend my Internet, as I believe my work I.T. would prefer to handle all access to their network.
Perhaps there is some documentation about doing this that you could point me to? I have not been able to find it.
Thank you for your help.Your original question was How to use Time Capsule for wireless back-up but not Internet?
There is no reason for you to connect the tower....or anything else...using Ethernet if your goal remains that same as you stated.
If you are asking if you can backup the Tower using Ethernet, and not wireless, then you can connect the tower to one of the LAN <-> ports on the Time Capsule....not the WAN port.
Yes, it appears to work without plugging into my tower.
Correct, it will work.
I just have to select the network that it created. Of course, I have no access to the Internet while this is happening and it can not auto backup, unless I am on that wireless signal.
As I stated, that is the downside to trying to back up without an Internet connection. You have to establish another network...and backup over that network.
If you are asking if you can stay connected to the work network while also backing up to your non-Internet "private" network, that is not possible. -
Can any one suggest me how to use drawPixels method for 40 series devices
Hello!
I am using drawPixels method of DirectGraphics class the code I have written is :-
Image offscreen=DirectUtils.createImage(width,height,0x00000000);// width and heights are integer value
public final int MODEL=DirectGraphics.TYPE_INT_8888_ARGB ;
Graphics offgra = offscreen.getGraphics();
DirectGraphics directgraphics = DirectUtils.getDirectGraphics(offgra);
directgraphics.drawPixels(imgData,false,0,width,0,0,width,height,0,MODEL); // imgData is a int array(int imgData[]) which contains required pixels of image.
The above code is working fine with NOKIA 60 series device but when i use it with NOKIA 40 series device it gives java.lang.IllegalArgumentException.
same time if i use :-
directgraphics.drawPixels(imgData,false,0,width,0,0,width,height,0,DirectGraphics .TYPE_USHORT_4444_ARGB ) ;
// imgData is a short array(short imgData[]) which contains required pixels of image. i have used different formet here.
it works fine with 40 series device,
can any one suggest me how to use drawPixels method for 40 series devices with format
DirectGraphics .TYPE_INT_8888_ARGB .If Remote wipe is activated it can't be undone. And Once the Wipe is done, the device can nö longer be tracked.

thank youHi,
I think you need to write the code for this from scratch (built on top of existing HTTP functionality). There may be open-source J2ME code you could use. I've never tried this so I'm afraid I don't know any more. But maybe that is what you were asking... i.e. does anyone have code that does this already...

how to use 2 GL for loss made on asset retirement w/o revenue.
hello everyone
i have some trouble.
my company want to use 2 GL account for asset retirement
example some time use GL 6500001 some time use 6500002
in standard configuration AO90 , field loss made on asset retirement w/o revenue, there is only one field.
so i can use only one G/L.
it' s not good if i must to change configuration (and transport request )every time that user need to change GL.
now i got one idea.
i know that table T095 keep account determinaton and GL account data.
so if i make program that change data from table T095 directly. i donot need to change config everytime.
but i am not sure that this way will make impact other standard program or not.
i will wait for better idea from everyone.
please help.Substitution consist of several steps each with two parts:
1- Prerequisite
2- Replacement
If the prerequisite is satisfied (TRUE), substitution (Replacement) is performed.
