Call a sequence with a variable

Hello!

I was wondering if it is possible to use a variable to call a sequence. So instead of typing a specific sequence in step of calling sequence, is it possible to use something like CurrentValue.String to choose which sequence should run?

Thank you

You can check the checkbox 'Specify expression' to determine the sequence that should be called. You can use variables in the expression.

Using ChnCalculate with a variable

The channel of LIN/LIN_Error has 3000 values inside. I want to add a correction value to each of the 3000 values inside.

If I use a constant, it works well. For example:

Call ChnCalculate ("Ch(""LIN/LIN_Error"") = (2 + Ch (" "LIN/LIN_Error" "" "))") adds 2 to each value.

However if I try with a variable it does not work.

Dim Corr

GlobalDim "Corr".

Corr = 2
Call ChnCalculate ("Ch(""LIN/LIN_Error"") = (Corr + Ch (" "LIN/LIN_Error" "" "))")

Hi Frank,.

The problem is your first line. By running 'Dim Corr' in the VBScript code, you force this variable name to refer to the variable in VBScript and not the variable global tiara - light color in the SCRIPT Panel does not reflect what is confusing. If you remove the statement Dim Corr, and then the VBScript code will correctly reference the global variable. Another way to put it is that your VBScript never affects the global variable to Corr 2. The command correctly done ChnCalculate() refers to the global variable of Corr, but it is always set to 0.

However, for this task, I'd recommend the ChnLinScale() function, which is simpler, will run faster, accepts regular VBScript variables and ignore so all this imbroglio.
```
Dim Corr

Corr = 20

Call ChnLinScale ("LIN/LIN_Error", "LIN/LIN_Error", 1, Corr)
```

How to call a sequence on a computer remote programmaticylly (using c#)?

Hello TS classmates!

I have succeedd local call from c# sequences inside but I cannot determine how to modify the code to call the sequence on a remote host.

Any suggestions?

using System;
using System.Collections.Generic;
using System.ComponentModel;

using System.Drawing;
using System.Linq;
using System.Text;

}

}
}

Hello weltaran,

The TS remote execution works in the following way:

You have a local engine with a local Executive who runs a sequence. This call sequence can be configured in

the sequence editor to be run in a new local thread of execution, or on a remote computer, which can be configured in the

step sequence-call the sequence file. This requires to set the options appropriate to the computer station remote and configuration of DCOM and Firewall settings

as indicated in Chapter 5 of the manual ref TS. To publish a remote TS-engine to other computers to access with directX on a client computer

is not recommended and tested by our side.

Best regards

Problems of execution of a SQL function with a variable in the WHERE clause

Hello world!
I have programmed a function that returns a boolean value based on the result of the SQL. It's the function:
FUNCTION existe_secuencial (seq_name VARCHAR2) RETURN AS BOOLEAN
cursor c2 is SELECT FROM all_sequences WHERE upper (sequence_name) = sequence_name' | seq_name | ' ;
BEGIN
OPEN c2;
DBMS_OUTPUT. Put_line (nombre_seq);
Get c2 INTO kk;
If c2% NOTFOUND = True THEN
RETURNS false;
on the other
RETURNS true;
end if;
END existe_secuencial;
And I give the floor to the function of a procedure in this way:
IF existe_secuencial ("SEQ_ARQUETA") = True THEN
DBMS_OUTPUT. Put_line ('exists');
ON THE OTHER
DBMS_OUTPUT. Put_line ("' NOT exists");
END IF;
The probrem that this SQL is forced to return results because this sequence exists in the comic book, but is not, return me the FALSE value. What makes me mad is that if I change the second line of the function in this way:
> > cursor c2 is SELECT FROM all_sequences WHERE upper (sequence_name) sequence_name ="SEQ_ARQUETA";
It works find and return of sequence existing (real)
Can someone help me please, I'm quite desperate to find what is the problem with that because I do not understand why if I built the slider with a variable returns no results so that if I do write it works...
Thanks in advance!
Itziar

Frame you your variable in quotes, which makes the string literal ' |. ' seq_name | "rather than the content of the variable.

I think that something like this would be an improvement.

function existe_secuencial (seq_name VARCHAR2) return a Boolean value as

number of exist_check: = 0;

Start

Start

Select 1

in exist_check

of all_sequences

where upper (sequence_name) = upper (seq_name);

exception

When no_data_found then

null;

end;

return (exist_check = 1);

end existe_secuencial;

Problem with the variable moveIntoFolder_Task

Hello
I spend a lot of time already trying to find how I can put VM I found in moveIntoFolder_Task.
What I'm doing:
1 create a folder
2. find a virtual machine provided in the text field
3. move this virtual machine in the target folder.
try {newFolder = parentFolder.createFolder ("test1") ;}
{catch (Err)}

findVM (vmname);
function findVM (vmname) {}
allVms = System.getModule("com.vmware.library.vc.folder").getAllVirtualMachinesByFolder (parentFolder);
RET = null; for (var i in allVms) {}
If (allVms [i] .name == vmname) {ret = allVms [i]; break; }} return ret;
}

var vms1 = new Array();
vms1 = [];
vms1 = vms1.push (ret);
task = newFolder.moveIntoFolder_Task (vms1);
var actionResult is System.getModule("com.vmware.library.vc.basic").vim3WaitTaskEnd (task, progress, pollRate);.

vms1 is VC:VirtualMachine type - but when I select this variable manually as an attribute - it works fine, I can't cmove VM in the target folder.
When I find this virtual machine by using the function {} findVM I get following error:
State: 'impossible', State of the business: "null" exception: ' cannot convert 1.0 [com.vmware.vmo.plugin.vi4.model.VimManagedEntity]

Do you know how I can convert VM to data type VimManagedEntity?

Hello

You have no need to convert the VM VimManagedEntity.

The problem is the next part of your code:
```
vms1 = vms1.push(ret);
task = newFolder.moveIntoFolder_Task(vms1);
```
It seems that you expect the first line to push the object ret at vms1 table and return the array object, which then you pass as an argument to the method moveIntoFolder_Task().

The problem is that the push() method will not return the table object, but the length of the array. So in fact you call moveIntoFolder_Task() method with the type argument number instead of argument array of virtual machines, and that's why you get this exception "cannot convert...". »

So the solution is to replace:
```
vms1 = vms1.push(ret);
```
with a little (no assignment)
```
vms1.push(ret);
```

How can I show a background image with a variable?

I try to explain it:

I have a div called "entrante1_ctn" that must contain a background image. This code works, but I don't want to do...

sym.getComposition () .getStage ().getSymbol("entrantes_sym").$("entrante1_ctn").css ('backgro undImage','url(images/entrantes/entrante1.png)');

I would like to the somtehing like that...

sym.getComposition () .getStage ().getSymbol("entrantes_sym").$("entrante1_ctn").css (' undImage ',' url backgro ( variable )');

The variable is a table element, but this code does not work:

sym.getComposition () .getStage ().getSymbol("entrantes_sym").$("entrante1_ctn").css (' undImage ',' url backgro ( ent_1 [0] )');

Please, helpp!

Hi or Hello,
- The principle( general case) ==> .css ("background-image ',' url(images/myImage.png)'");
- With a variable (a variable):
var image = "images/myImage.png ';

. CSS ("background-image", "url (" + image +') ');
- Your particular case (your case) ==> .css ('background-image', ' url ('+ ent_1 [0] + ')');

Assign a value of "dynamically created the sequence" to a variable
in my procedure I am creating a sequence on the fly, I prepare the name with some parameters passes as below

.
.
v_seq_name: = "seq_". loadid | v_table_name;
run immediately 'CREATE SEQUENCE'. v_seq_name | "MINVALUE 1 MAXVALUE 999999999999999999999999999 START WITH 1 increment of 1 hiding 20';
.
.

and now after doing some operations I need to assign the current value of the sequence to a variable number, I tried but does not subsequently

(1) v_curr_value: = v_seq_name.currval;
(2) select v_seq_name |'. nextval' in double v_curr_value;

can you please suggest me how can I get the value in plsql block.
And what is - this?

v_curr_value: = v_seq_name.currval;

Of course, it will fail. If you want to get currval in a sequence whose name is stored in a variable, you must use dynamic SQL:
```
SQL> declare
  2      v_seq_name varchar2(30);
  3      loadid number := 1;
  4      v_table_name varchar2(10) := 'tbl';
  5      v_curr_value number;
  6  begin
  7      v_seq_name := 'seq_' || loadid || v_table_name;
  8      execute immediate 'CREATE SEQUENCE ' || v_seq_name ||
  9                        ' MINVALUE 1 MAXVALUE 999999999999999999999999999 START WITH 1 increment
by 1 cache 20';
 10      for i in 1..5 loop
 11        execute immediate 'select ' || v_seq_name || '.nextval from dual'into v_curr_value;

How to fill out the "to:" line with a variable email address?

I'm new to coding and am not sure how to ask my question. I have a link in an 'Email' symbol that I would like to have the window open to a 'mailto', but there are several instances of that symbol on the timeline, each using a different email address. If the [symbol]. Email.Click code reads as follows:
Window.Open ('mailto:'+ sym.getVariable = ("emailWindow"), "_self")
and the line in the Stage.creationComplete code that is supposed to call the variable code reads:
sym.getSymbol("Details_David").$("Email").html ("[email protected]" "").setVariable("emailWindow","[email protected]");
With this code, the browser opens a window of mailto, but the ' to: ' line readings, "indefinite".
Either in the [symbol]. Email code. Click, I have:
Window.Open('mailto:"emailWindow"',"_self")
without the "emailWindow" as the variable name, the "to:" line to the mailto line reads, "emailWindow".
How to fill out the "to:" line with a variable email address?

Otherwise, it works better:

1)

replace

sym.getSymbol("Details_David").$("Email").html ("[email protected]").setVariable("emailWindow", "mailto:[email protected]");

with

sym.getSymbol("Details_David").$("Email").html ("[email protected]");

Call a script with several parameters
OK, it seems that it would be an easy question, but I have googled this to death and I can't find anything. How to pass variables to a script? I have a script with three variables, and only the first is necessary. I'm eager to make the BACK and SQLPlus command line. The only difference is that I would need to call information more SQLPlus connection when I call back.

I tried using single quotes, double quotes, I tried to delimit it with a space, the command and the semicolon, but nothing works.
```
sqlplus user/pwd@db @"F:\Script.sql" variable1 "" variable3
```
When I run the present, it always pushes me to the three variables. Once again, the only variable 1 is required. The variables 2 and 3 will be more often then not be blank. Any help would be appreciated.

I'm on 10.2.0.4 if it's important.

Apparently, you're never set variables such as & screen before you try to use them. Don't do this; set them all first.

When you call a SQL * more script like this:
```
@"F:\Script.sql" variable1 "" variable3
```
who defines and assigns values to variables substitution & 1, & 2 automatically and & 3
& 1 is 'variable1' in the example above,
& 2 is an empty string, and
& 3 is "variable3.
You pouvez use these variables in your script, like this:
```
...
   v_screen           := UPPER ('&1');
   v_app_layer_custom := UPPER ('&2');
   v_table            := UPPER ('&3');
```
but it is better to use meaningful names, like you do. To do this, copy the values & 1, & 2 and 3 & to & screen & layer_override and & table at the beginning of the script:
```
DEFINE     screen          = "&1"
DEFINE     layer_override     = "&2"
DEFINE     table          = "&3"

DECLARE
   v_screen            VARCHAR2 (40);
   v_app_layer_custom  VARCHAR2 (4) := '';
   v_table             VARCHAR2 (40);
BEGIN
   v_screen           := UPPER ('&screen');
   v_app_layer_custom := UPPER ('&layer_override');
   v_table            := UPPER ('&table');

getURL() does not work with the variable
I have a button that does two things:
First of all, it opens a new Flash movie in a new window, using the line:

getURL ("javascript:OpenBrWindow('/movie2.asp','MyMovie','status=0,scrollbars=1','865','690_','true')");

It then redirects the original window to another URL by using the line:

getURL (" http://www.mydomain.com")

This works very well when the two lines are combined into an instance of button as follows:

on (release) {}
getURL ("javascript:OpenBrWindow('/movie2.asp','MyMovie','status=0,scrollbars=1','865','69_0','true')");
getURL (" http://www.mydomain.com")
}

But if I set a variable to contain the first url, replace the url with the variable, the new window never opens.

Here's the new code:
It is located in frame 1:
MyURL = "javascript:OpenBrWindow('/movie2.asp','MyMovie','status=0,scrollbars=1','865','690','tru_e')";

This is the new code behind the button instance:
on (release) {}
getURL (myurl);
getURL (" http://www.mydomain.com")
}

The second command, redirection, works, but a new window never opens to the other film.

Any ideas?

Thank you
Beth

Okay - with some trial and error I figured it. I discovered that the variables declared and populated in the timeline not copied to the button unless they are configured as global variables. Call of my variable _global.myurl did the trick.

Incremented in trigger without call nextval sequence

Why when I call an insert with a value for my seq_test01 my obtained sequence column incremented?

INSERT INTO test01(test_string) VALUES ('Insert #1');
SELECT * FROM test01; 

INSERT INTO test01(test_string) VALUES ('Insert #2');
SELECT * FROM test01; 

INSERT INTO test01(test_string, seq_test01) VALUES ('Insert #3', 1);

How can I evaluate a variable with another variable?
Hi all
I'm working on the ODI which need to have a control loop that evaluate a variable (let's say it's 'ABC') with another variable (let's call it "XYZ"). Seems it should work, but I got the following error in the execution:
-error message-
java.lang.NumberFormatException: for input string: "YZ".
......
-----------------------------
In the evaluate text box, I put in "#XYZ" (without the quotation marks in the text box). But the error message indicates that the input string of the error is "YZ", i.e. without the first 2 characters. I also tried ': XYZ ' and also '#PROJECT. XYZ", but received the same error.
Can anyone help? Or advice are welcome, thx.
Hello

You are working in an Oracle database?

As I nevet had this kind of variable interaction works, I've used a workaround as:

Add a step to refresh in the procedure as:

Select case when #var1 = #var2
then 0
1 other
end
of the double

Now you have 2 knew 1 for false and 0 for the real values simply create an evaluation of 0 or 1 (fixed).

Make sense?

Adjust the data in the database with the variables

Hello

For my internship, I have an assignment to read and set a database with the variables. This SQL server 2005 database contains variables of a controller. These are read and write variables. The assignment is to display the read variables and the user can adjust the variables of Scripture. The first part was "easy" because the forum contained a lot of examples of this. The second part is more difficult because the forum contains absolutely no example of this. Can I use LabVIEW 2010 and 2011, and also I downloaded the 30 day trial of the database connection tool. If it's useful, I can recommend my company to buy this package. Playback vi makes use of a UDL (Microsoft data link) connection.

So you guys my question is: is it possible to adjust the specific variables in a database using LabVIEW? And maybe you can give me a little advice on this topic...

Thanks in advance!

Roy

In SQL, the specific data are always selected with the keyword WHERE. In VI to update there is a link for options, you can for example add a constant 'WHERE id = 1457 and measure > 0.54 ".

You can ofc. also build this chain through controls, settings and other means.

If you prefer, you can use the Execute Query (under Advanced tab I think) to which you can send the complete query example "TestTable Update set name ="Zeus"where id > 14 and id.<>

With a variable number of input ports on a Subvi

How can I have a Subvi with a variable number of input ports that can be changed in the other VI that uses the Subvi?

You can't actually do what you trying to do, how LabVIEW is implemented does not screw created by the user with arbitrary entries. And to be honest, there is probably a better way to do whatever it is you want to do.

If you really really want to do that, but... you can come kind of close.

1. create a new VI

2. change its connector to the one with the inputs and outputs pane more possible (terminals 8-6-6-8, 28)

3 create controls/indicators for any desired input/output of not scaling can connect the (i.e. the error in / error, son of reference, etc.)

4. hang them until the connector pane

5 count how many entries are left and create a control for each entry and their son all

6 drop your VI on the block diagram of the VI one another as a Subvi

7. Note that when you mouseover, it looks like a Pincushion

8. right click the VI and uncheck the "display as icon".

9. you can now "slide down" at the bottom of the VI

The terminals in the section "slide down" are as a package by name or node property that you can click on them to reallocate them to what it is not already selected. The default is to make all the entries in alphabetical order, then all the outputs in alphabetical order. If you rename the terminals that allows you to make appear in the order that you prefer is up to you.

As all terminals, for the best that you can do to detect if they are wired is to define a default value that should never be used. If she is floating points, you can use 'NaN' or 'Inf '. If this is a cluster that you did, add an item more boolean which is true in the default values for this entry VI.

Then just wire up all the identical terminals together in a table, filter the items which appear to be unwired and make all your treatment on the rest.
