How to get Coordinates of edges from image into excel

Hi,
I am new to labview and I am doing a project in which i move an XY stage under a laser to etch pictures. So far I have managed to get the stage to move by reading off coordinates from an excel spread sheet and so can draw pictures if I have the coordinates.
I am trying to use the vision module to be able to put any image in and then find the edges, get the coordinates of the edge and so draw the image. Using the vision assistant I do colour plane extraction (to make greyscale) then use shape detection looking for lines with a small minimum length, this gets the information i want and if i click the button on the right that says send data to excell i get a spread sheet with all the information i need. However, I cant get it to automatically save to excell (the write to spread sheet function doesnt work as "The type of the source is 1-D array of cluster of 5 elements."
It would probably be bettter if i could use the output of the vision assistant (shape detection) straight away without having to save to excell but I cannot extract the information i need from the output as none of the array/cluster functions seem compatible with the data. I am using labview 10 and have attached my VI below any help would be greatly appreciated!

Hello hzub1,
It seems your having trouble getting to the information in the output of your Vision Assistant. You can use Context Help (Ctrl+H to show) to help understand the contents of a large array or cluster when you hover your mouse over the wire (see below).
Looking at the above I created the code below which breaks out all the contents of one item in the array.
Here I use the Index Array function to break out one element of the array. Each element is a circle descriptor, cluster of 5 elements so I use the Unbundle by Name function to access each of the values in the cluster
I hope this helps,

How to get an opening title from imovie06 into imovie09 ?

There is a opening title I really want from imovie06 which is not available in imovie09 is there any way of getting it ? or how to import it please.

Prepare your title in iMovie HD 6, then export the movie. Go to Share>QuickTime and select Full Quality.
Before starting your Title project, make sure you set it up as the same aspect ratio as your proposed iMovie '09 project, that is, Standard 4:3 or Widescreen 16:9.
The exported movie can be imported to iMovie '09 by selecting File>Import>Movies from the Menu.

How to get the forecast data from SCM into BW

Hello,
Is there a table or Function module in SCM F&R that can be used to transfer the forecast data from SCM F&R into BW? I dont see any Business content datasources that has the forecast data.
I would like to get the future forecast data. For ex, if there is a forecast for a material and Site for the next 52 weeks, I would like to retrieve
the same from SCM. I dont see any business content. The closest would be 0FRE_ANA_WEEKLY_1. But it has only the past data, not the future data.
Thanks,
SBS.

Hi,
You would follow the same process as you would for getting data from a R3 system to BW, i.e generate datsources on the APO side and then set the extraction to flow from APO to BW. On the BW side, you'll need a source system for the APO, replicate datsources, set up update and transfer rules in the infosource and then load data to the data targets.
Cheers,

How to get all the values from the dropdown menu

How to get all the values from the dropdown menu
I need to be able to extract all values from the dropdown menu; I know how to get all those values as a string, but I need to be able to access each item; (the value in a dropdown menu will change dynamically)
How do I get number of item is selection dropdown?
How do I extract a ?name? for each value, one by one?
How do I change a selection by referring to particular index of the item in a dropdown menu?
Here is the Path to dropdown menu that I'm trying to access (form contains number of similar dropdowns)
RSWApp.om.GetElementByPath "window(index=0).form(id=""aspnetForm"" | action=""advancedsearch.aspx"" | index=0).formelement[SELECT](name=""ctl00$MainContent$hardwareBrand"" | id=""ctl00_MainContent_hardwareBrand"" | index=16)", element
Message was edited by: testtest

The findElement method allows various attributes to be used to search. Take the following two examples for the element below:
<Select Name=ProdType ID=testProd>
</Select>
I can find the element based on its name or any other attribute, I just need to specify what I am looking for. To find it by name I would do the following:
Set x = RSWApp.om.FindElement("ProdType","SELECT","Name")
If I want to search by id I could do the following:
Set x = RSWApp.om.FindElement("testProd","SELECT","ID")
Usually you will use whatever is available. Since the select element has no name or ID on the Empirix home page, I used the onChange attribute. You can use any attribute as long as you specify which one you are using (last argument in these examples)
You can use the FindElement to grab links, text boxes, etc.
The next example grabs from a link on a page
Home
Set x = RSWApp.om.FindElement("Home","A","innerText")
I hope this helps clear it up.

Hi,
What kind of web page do you have? Do you have possibility to for example make RFCs? Then you could trigger events (with parameters that could "return" the values) and the workflow could react to those events. For example your task can have terminating events.

Hi
Thanks, that will work, but then I'll have to insert code into all my reports.
I can see that "Application Server Control Console" is able to rerun a report.
This must mean that the Report Server has access to the runtime parameters.

How to get the path of the image stored in sap??

Hi All
The problem is
While making an entry in standard there is a field called documents through which we attach our images in sap.
How to get the path of the image stored with the corresponding order so that the image can be displayed while we are creating a report.
I know how to upload the image while creating a report using docking control.
I am not able to get the path of the image stored...
Please Help
Thanks in advance..
Pooja

I am not aware of exactly which tables are used for storing the attached doc. details, but we have worked in the similar requiremnent.
What you can do is .... before uploading the image to any order, try swich on the SQL trace ST05 and after upload switch off.
The log will display what are the tables involved while storing the image. And you can easily find out the image location.

Hi,
I did a test with your code in my environment and it works fine.
For a better troubleshooting, I suggest you debug your code step by step. You may need to check if file.ListItemAllFields.ID is valid.
If you want to get video Thumnail image, there is a column named Preview Image URL, the internal name of the field is AlternateThumbnailUrl.
You can get the field value using Sever Object Model like below.
String url = item[“AlternateThumbnailUrl”].ToString();
Here is a similar thread for your reference:
