sorting table, how to get the new index of the last value?

Hi all!

I use a Subvi, which adds a cluter of the parameters to an array and then sort this table by one of the parameters in clusters.

It works very well, with examples, that I found in this forum

but now, I would like to know if it is possible to obtain at the end of the new cluster index first added.

See attached VI

Thank you

You take the size of the table and insert the new element to this level is anything other than the table of construction and a simple construction would do that.

In your question, I assume you're asking on the index of the item that you inserted after the sorting of the table, right? In this case, you can compare the cluster element that you introduce to the initial with the cluster table you get after a sorting of the table. This will give you the index of the item that you insert at the start.

DVT:pivotFilterBar - how to get the selected values of the filter
Hi all

I have a question: how to get the selected values from the pivot table filter bar programmatically?

I tried to use
```
pivotTable.getDataModel().getDataAccess().getValueQDR(startRow, startCol, DataAccess.QDR_WITH_PAGE);
```
but to the edge of the side DATA INCORRECTESdeclarations page, it seems that it will return the cached values.

Environment: JDev 11.1.1.3.0 without tasks.

Thank you
Miroslaw
Hello

You can retrieve the value selected in the PivotFilterBar through the PivotFilterBar model, instead of dataaccess:

Download the template of the bar pivot filter instance
QueryDescriptior queryDescriptor = (QueryDescriptor) pivotFilterBar.getValue ();

retrieve a list of criterion, each of them is used to fill each lov in the pivot filter bar
ConjunctionCriterion conjunctionCriterion = queryDescriptor.getConjunctionCriterion ();
List criterionList = conjunctionCriterion.getCriterionList ();
for (int i = 0; i)<_criterionList.size(); i++)="">
AttributeCriterion = (AttributeCriterion) criterionList.get (i) criterion.

_selected is the currently selected value
Selected object = criterion.getValues () .get (0);

System.out.println (_selected);
}

Hope that helps,
Chadwick

Hi, guys! Does anyone know how to get the RGB value of a pixel in a psd document using scripts in Photoshop? I myself have missed for a long time and could not resolve. I am very happy to hear your voice as soon as possible!

Here is an example...

var originalUnits = app.preferences.rulerUnits;

var doc = activeDocument;
var Colour1 = GetHexColour(eyeDropperRGB(1,doc.height-1));
var Colour2 = GetHexColour(eyeDropperRGB(20,doc.height-5));
var Colour3 = GetHexColour(eyeDropperRGB(40,doc.height-14));
alert("Colour 1 = " +Colour1 + "\rColour 2 = " +Colour2 + "\rColour 3 = " +Colour3);
var decColour = eyeDropperRGB(40,doc.height-14);
alert("Red = " +decColour[0] + "\rGreen = " +decColour[1] + "\rBlue = " +decColour[2]);
app.preferences.rulerUnits = originalUnits;
function GetHexColour(reqHex){
var out='';
for(No in colours = reqHex){
 out = out.concat(zeroPad(d2h(reqHex[No]),2));
 }
return out;
};
function eyeDropperRGB(x,y) {
 var x2 = x + 1;
 var y2 = y + 1;
 var out = new Array(3);
 activeDocument.selection.select([[x,y], [x2,y], [x2,y2], [x, y2]], SelectionType.REPLACE, 0, false);
 for(ch in list = ["Red", "Green", "Blue"]) {
 histogram = activeDocument.channels[list[ch]].histogram;
  for (i = 0; i <= 255; i++) {
   if (histogram[i]) {
    out[ch] = i;
    break;
   }
  }
 }
  return out;
};
function d2h(d) {return d.toString(16);}
function zeroPad(n, s) {
   n = n.toString();
   while (n.length < s)  n = '0' + n;
   return n;

How to get the internal values of Photoshop one ID assigned

I have difficulties to obtain values for the internal settings. It's less hard to set, you can use the Listener Script to get the code to use. Presumably, you use executeActionGet() with an ActionReference. The problem is to know how to build the ActionReference. It doesn't seem to be a lot of documentation on that.
My immediate problem is how to get the parameters of the 3D camera. I know this requires Photoshop Extended, but the principle must be the same. This code sucessfully defines these parameters:
< code >
function setPhotoshopCamera (angleX, angleY, angleZ, posX, posY, posZ) {}
Camera
var idGet3DCamera = stringIDToTypeID ("get3DCamera");
var idSet3DCamera = stringIDToTypeID ("set3DCamera");
var descCamera = new ActionDescriptor();

Camera position
var idKey3DCurrentCameraPosition =
stringIDToTypeID ("key3DCurrentCameraPosition");
var descCameraPosition = new ActionDescriptor();

var idkeythreeDXPos = stringIDToTypeID ("key3DXPos");
descCameraPosition.putDouble (idkeythreeDXPos, posX);
var idkeythreeDYPos = stringIDToTypeID ("key3DYPos");
descCameraPosition.putDouble (idkeythreeDYPos, posY);
var idkeythreeDZPos = stringIDToTypeID ("key3DZPos");
descCameraPosition.putDouble (idkeythreeDZPos, posZ);
var idkeythreeDXAngle = stringIDToTypeID ("key3DXAngle");
descCameraPosition.putDouble (idkeythreeDXAngle, angleX);
var idkeythreeDYAngle = stringIDToTypeID ("key3DYAngle");
descCameraPosition.putDouble (idkeythreeDYAngle, angleY);
var idkeythreeDZAngle = stringIDToTypeID ("key3DZAngle");
descCameraPosition.putDouble (idkeythreeDZAngle, angleZ);
descCamera.putObject (idKey3DCurrentCameraPosition,
(idKey3DCurrentCameraPosition, descCameraPosition);

These must be defined in the ActionDescriptor to make it work,
// , but we do not have them
var idkeythreeDCurrentFStop = stringIDToTypeID ("key3DCurrentFStop");
descCamera.putDouble (idkeythreeDCurrentFStop, 0.000000);
var idkeythreeDCurrentFDist = stringIDToTypeID ("key3DCurrentFDist");
descCamera.putDouble (idkeythreeDCurrentFDist, 0.500000);
var idkeythreeDCurrentFocalPointX = stringIDToTypeID ("key3DCurrentFocalPointX");
descCamera.putDouble (idkeythreeDCurrentFocalPointX, 0.500000);
var idkeythreeDCurrentFocalPointY = stringIDToTypeID ("key3DCurrentFocalPointY");
descCamera.putDouble (idkeythreeDCurrentFocalPointY, 0.500000);
var idkeythreeDCurrentFOV = stringIDToTypeID ("key3DCurrentFOV");
descCamera.putDouble (idkeythreeDCurrentFOV, 30.000000);
var idkeythreeDOrthographic = stringIDToTypeID ("key3DOrthographic");
descCamera.putBoolean (idkeythreeDOrthographic, false);
var idkeythreeDOrthographicScale = stringIDToTypeID ("key3DOrthographicScale");
descCamera.putDouble (idkeythreeDOrthographicScale, 6.928203);
var idkeythreeDViewIndexString = stringIDToTypeID ("key3DViewIndexString");
descCamera.putString (idkeythreeDViewIndexString, "");

var / / desc = executeAction (idSet3DCamera, descCamera, DialogModes.ALL);
return of ESCR;
}
< code >
The problem is that it does not work unless you also set the lower elements. I want to leave what they are currently defined, but I don't know how to get these values. Apart from that, I'll get the values of position of camera beforehand. 9 ID, string or otherwise, this should be necessary are known from the top.
I assume you are using something like:
< code >
Var ref = new ActionReference();
ref.putIndex (idkeythreeDCurrentFStop, idkeythreeDCurrentFStop);
var / / desc = executeActionGet (ref);
< code >
However, I was unable to get something to work. I am not sure
1. That of the putXXX method to use.
2. What to use for the desiredClass, which is the first argument.
Any help would be appreciated.

That you will get the 3DCurrentCameraPositon
```
var ref = new ActionReference();
ref.putEnumerated( zTID("Lyr "), zTID("Ordn"), zTID("Trgt") );
var desc = executeActionGet(ref).getObjectValue(stringIDToTypeID('layer3D')).getObjectValue(stringIDToTypeID('key3DState')).getObjectValue(stringIDToTypeID('key3DCurrentCameraPosition'));
```
Which returns a descriptor with the following keys.

Key 0 = key3DXPos: DescValueType.DOUBLETYPE
1 key = key3DYPos: DescValueType.DOUBLETYPE
2 = key3DZPos key: DescValueType.DOUBLETYPE
3 = key3DXAngle key: DescValueType.DOUBLETYPE
Key 4 = key3DYAngle: DescValueType.DOUBLETYPE
5 = key3DZAngle key: DescValueType.DOUBLETYPE

At least with my sample 3D layer. I don't really do a lot with the 3D, so there may be other keys.

How to get the peak value

Can I know how to get the 2 peak values v1 and v2 and 2 duration times t1 t2.

Since there is a small amplitude noise, difficult to use the Max simplely.

May need to use a filter such as wavelets or TREE to Denoise it first. Can I know how to use, any Toolbox in labview. How do the curve smooth first.

Thank you.

I can't watch your vi now (I'm at work), but if your signals are long enough, you might consider a median filter. You can set the number of points before and after use. I found that it is useful for some smoothing problems (not all).

How to get the parameter values of a step type custom when I create file and adding a type of step seq

I use lv 8.5 and teststand 4.0.

I did a step type custom and recorded at the MyTypes.ini in pallets of type.

I specified a default module by opening the properties of the custom step of *.ini type window, then I put some values of the parameters.

T1) when I open teststand and I add the custom step type manaully in seq file, the labview module parameter values are represented.

But, if to use file (create and add support prototype stage), the labview module parameter values has the default value.

Using joint file, how to get the setting custom step type values I put in *.ini?

Q2) each type of step are automatically by name through the use of LoadTypePaletteFilesEx. When I open teststand and I add the custom step type manaully in seq file, the module is loaded automatically. Inside the attachment, I use a prototype of charge and a fixed path where the module labview is to load the labview module.

Can I load module automatically without using a prototype of charge or how can I get a dynamic path of type step?

I solved Q1 for myself by using the mapping tab of the parameter within the configuration to the default module window.

Everyone knows Q2?

Thank you.

How to get the last access to the workflow? (OM, WMS) release 11.5.9

Hello my friends.
I am looking for information on how to get the date of the access and the user name who did use some WFs in OM and last WMS.
If it is through the application or running in the background via SQL for the information is not important to me.
Could you help me with this?.
Thank you

the 'item_type' attribute must match the name of the WF?

Yes (internal name. For example OEOL).

The custom of those who will not be affected by the upgrade.

You must run the query that I provided before to identify if the workflow is used or not.

For the workflow of order lines, it is intended to be used as you use the order management.

Kind regards

As Ftsiot said in this post, it will work only to exclude the sat and Sun. Another one if you want to exclude regional holiday, you may need a calendar in DB table.
