Is it possible to separate U32 value into four U8 values?

Hello all...
I'm working on a project where I need to use electronic load and set it on different values..To communicate with electronic load I need to give commands in HEX format... The format I have to use is an array of U8 with 26 byte... Each byte is dedicated for some purpose... Like
1st byte - start bit
2nd byte - address
3rd byte - command
4th byte - the lowest byte of voltage value
5th byte - the lower byte of voltage value
6th byte - the higher byte of voltage value
7th byte - the highest byte of voltage value
and the manual says
"represent voltage by 4 bytes of HEX. Lower byte are in the front location, higher bytes are in the latter location. For example : voltage is 16.000V, HEX code is 0X00003E80, 4th byte 0X80, 5th byte is 0X3E, 6th byte is 0X00, 7th byte is 0X00."
in program I'm taking input voltage from user which in decimal format like 16V... Now rest work should done by software i.e. converting into HEX n separating it into 4 bytes... Enter into array...
my problem is I'm not able to separate it from U32 to U8. Can anyone please help me...?
thank you.
Solved!

I don't know how you get from 16V to x00003E80, so most likely the manual would provide more information on the details.
If the voltage is actually 4byte SGL (16 (SGL) is however x41800000), you would simply make one small modification as shown here.
In any case, this should get you enough ideas to get started. Good luck!

Is there possibility to add dimension value into hierarchy using dml or spl

1 Is there possibility to add dimension value into hierarchy using dml or spl?
If such possibility exists how to do that.
2 Is it possible to sort dimension values inside one branch of the hierarchy?

What version of OLAP are you using and how did you create your AW (e.g., AWM)?
Assuming that you're used either AWM or the Java API for AWs in 10g, there isn't an OLAP DML for adding a dimension member to a dimension (and have all the meta data kept in sync); you must load dimension members using AWM the Java API for AWs.
So, make your changes in the the dimension table and process that table.
For sorting, you can add a sort attribute to the dimension. Add the sort attribute to the model, indicate that it's used for sorting, add the sort attribute to your dimension table and maintain the dimension.

Parameter validation failed. It is not possible to provide valid values for all parameters

I'm trying to test passing in parameter values from the URL. I have RS 2008 . I created an ultrasimple report based on a stored procedure output. There is no validation, No available values, No default values.
I'm trying to run the report like this:
/Reports/Pages/Report.aspx?ItemPath=%2fProduction%2fDBA+Reports%2fTest&iTest=1
I get:
Parameter validation failed. It is not possible to provide valid values for all parameters. (rsParameterError)
the one int parameter is iTestId
The RS log file says the following:
processing!ReportServer_0-54!9138!01/25/2013-09:22:51:: e ERROR: Throwing Microsoft.ReportingServices.ReportProcessing.ReportProcessingException: Parameter validation failed. It is not possible to provide valid values for all parameters., ;
Info: Microsoft.ReportingServices.ReportProcessing.ReportProcessingException: Parameter validation failed. It is not possible to provide valid values for all parameters.
What am I missing?

Hi F-ram,
From your description, you want to pass multiple parameters via URL, right? To pass multiple parameters through URL, we can use an ampersand (&) to separate them. For example, I have a report with two parameters p1 and p2. The report is deployed in a
folder on the Report Server. When I navigate to the report on the Report Server, I can see the report URL is http://localhost/ReportServer_SQL2008NEW/Pages/ReportViewer.aspx?%2fFolder%2fReport&rs:Command=Render.
If I need to pass parameters through URL, I can just add &p1=value1&p2=value2 at the end of the URL and the entire URL would be http://localhost/ReportServer_SQL2008NEW/Pages/ReportViewer.aspx?%2fFolder%2fReport&rs:Command=Render&p1=value1&p2=value2
If you have any questions, please feel free to ask.

Is it possible to use the value of a string to reference a component in the

I'm fairly new to Java so this may be a stupid question!
Is it possible to use the value of a string to reference a component in the code? For example in the code below, Wall is a class holding 3 different arrays. The Robot class has an array called finishBricks. When the buildWall method is run it receives the integers width and height which are used to construct the dimensions string. I want to use this string to then load the appropriate Wall array into the finishBricks array.
I hope this makes sense! Any help would be greatly appreciated!
class Robot {
public double[][] finishBricks;
public void buildWall(int width, int height) {
Wall w = new Wall();
String dimensions = "Wall" width "x" +height;
this.finishBricks = w.xxxx; // where xxxx is replaced by whatever the String dimensions is
class Wall {
     public double[][] Wall4x2 = {
          {-30.00,-01.60,27.45},
          {-30.00,-06.75,27.45},

Is it possible to set valid values at run time?

Hi,
I'am using a BPM Presentation and I want to know if it is possible to set the values of a combo box depending of the value of other field in the same presentation ando if so how to do it? I tried to do somethin like:

Hi, thanks Anup
I followed your advise but i didn´t success. I have question, if I'm getting the default values of a field with a method using a query. The type field is String and I'm using it into a combo box so the method I'm using returns a String[], is something like this:
for each row in SELECT column
FROM DataBase.SYSBPM.TABLE
where var1 = var2
do
clases[] = row.clase
end
return clases
But if I use a method for the onChange property if the field how to set the default values?
I tried with
for each row in SELECT column
FROM DataBase.SYSBPM.TABLE
where var1 = field1
do
clases[] = row.clase
end
clases = claseValidValues()
But this is not working, do you have any ideas??
Thanks

Merging two separate MUSE sites into a single MENU system and Paid & online BC eCommerce site

Hi all! I am stuck trying to figure out a Process Conundrum:
1> I have a BC site with e-commerce ready to go - paid - online with store template in place.
2> I also Have a 2nd MUSE created web site (with the client content/pages) that needs to merge with that E-commerce BC site.
What is the move to merge the two separate sites into a single site with the Menus all in proper order?
Is this simple and I can not see it? (merge the two sites in a folder and reopen in muse for new menus?
Or do i need Dreamweaver to assist in the merge?
In other words:
What is the PATH/PROCESS to merge a 2nd MUSE designed web site (sans e-commerce), in order to tie into the online BC e-commerce template paid site - so the menus update together as "one" site?
Menu Update Concern: merging two separate MUSE sites into a single MENU system with the "Paid on line Active BC e-commerce Template". How do it do it Process wise so that the menus adjust automatically... so they are "one" menu.
Reminds me of an old joke: Q: "What did the Buddhist say to the hot dog vendor at the ball park?"
A: "Make me one with everything!"
ONWARD>>>>>
Possible paths I am about to take attempting to Solve the problem - and scale the learning curve...
download the BC e-commerce site into Dreamweaver -
export the 2nd muse site by publishing it to a unique folder.
combine them by going back into dream weaver and attempting to figure out linking the menus. - perhaps they are automatic there too.
or load them both up to BC and back down to MUSE to fix the menus?
I appreciate Any recommendations, hits or humor that you could help on this.
Cheers!

Thanks, Liam... I will get it eventually...
Sadly: I do not have a budget to hire this out...
   - I have gone through lots of the BC and Muse training exercises. Adobe
   and BC Gurus.
But... if the only problem is that I need to work though my partner site BC
interface...
   - that would be fine...
   - so would using dream weaver....
I will go back and review the BC interface and also dreamweaver
capabilities.
without a budget... i need to figure it out... please do point to any
material or training you might be able to point me to.
I don't have to use muse, if that is my sticking point. I just need to get
the project up and BC looks perfect.
Thanks.

How can I separate one column into multiple column?

How can I separate one column into multiple column?
This is what I have:

BUYER_ID PHONE_NUMBER EMAIL CURRENCY
0001 555-555-0001 [email protected] USD
0002 555-555-0002 [email protected] USD
0003 555-555-0003 [email protected] CAD
Any help would be greatly appreciated.

This is another solution. Suppose your actual table's name is test(which has the redundant data). create a table like this:
CREATE TABLE test2 (BUYER_ID number(10),PHONE_NUMBER varchar2(50),EMAIL varchar2(50),CURRENCY varchar2(50));
then you will type this procedure:
declare
phone_number_v varchar2(50);
EMAIL_v varchar2(50);
CURRENCY_v varchar2(50);
cursor my_test is select * from test;
begin
for my_test_curs in my_test loop
select ATTRIBUTE_VALUE INTO phone_number_v from test
where person_id=my_test_curs.person_id
and attribute_name ='PHONE_NUMBER';
select ATTRIBUTE_VALUE INTO EMAIL_v from test
where person_id=my_test_curs.person_id
and attribute_name ='EMAIL';
select ATTRIBUTE_VALUE INTO CURRENCY_v from test
where person_id=my_test_curs.person_id
and attribute_name ='CURRENCY';
INSERT INTO test2
VALUES (my_test_curs.person_id,phone_number_v,EMAIL_v,CURRENCY_v);
END LOOP;
END;
Then you will create your final table like this:
create table final_table as select * from test2 where 1=2;
After that write this code:
INSERT ALL
into final_table
SELECT DISTINCT(BUYER_ID),PHONE_NUMBER,EMAIL,CURRENCY
FROM TEST2;
If you have a huge amount of data in your original table this solution may take a long time to do what you need.

I have not optimized the code (it's a bit slow). Is this what you are looking for?
See attachment in LV8.2
It does not sort the arrays but splits them in the order as they are found. The front part of the code is to generate 500 random numbers in two groups 100 to 109 & 300 to 309, to represent the numbers you have shown.
R
EDIT: Question: When you say "split in real time", are the numbers already into an array or it is prior to being in an array?

Where it is possible to change the value separator in Custom Field?

Hello,
This is a question around the "Custom Fields" and "Lookup Table"
I linked a "Custom Field" to a "Lookup Table".
I select the option "Allow multiple values to be selected from lookup table"
When I used this "Custom Field" in a view, the selected values are separated by a comma ",".
Where it is possible to change this value?
I saw another project server where the character is a semi-column ";" and I would like to test with ";".
Thank you in advance

Hi,
This will be triggered by your regional settings.
Hope this helps,
Guillaume Rouyre, MBA, MVP, P-Seller |
Hello,
Thank you for the answer.
Do you mean the "local regional settings"?
Because, depending on the PWA site I'm connected to I don't have the same values. I'm obviously using the same workstation.

How can I combine separate pdf documents into one document with several pages

I have been using Preview to separate pdf pages into separate pdf documents. How might I do the reverse. Preview appears to have combined the documents in the thumbnail, but will not allow saving this. It just saves the highlighted page.

Open all the documents. Choose View > Contact Sheet. All the pages will be shown as thumbnails, separated by document. Select the pages you want in the final document and drag them into the desired order, in one document space.
