How to create a circle with the origin not at (0,0)
I want to create a circle but the origin is not at (0,0).
I have the following data;
- point coordinate (X1,Y1)
- radius of the circle
Also, I want to create a line between the origin and the point (X1,Y1).
Kindly show me how can I do this. Thank you very much.
The accuracy of the GPS Receiver is +/- 0.5 meter. Its a Novatel product (Flex Pak). I am getting the string data from the GPS receiver. I took the Longtitude data as for my X and Latitude data for my Y. I took the Longtitude and Latitude data from the center of post for my reference calculation only to get the true value of X and Y at the end of the boom. I call the X and Y value at the end of the boom as dynamic because it always give me the value wherever the boom goes. Please see the attached sample VI's.
At one point , I actually measured, using a tape measure, the distance from the end of the boom to the center of post and i am getting the correct radius. But when I rotate the boom on the other side it will give me a different radius. And looking at this radius value, while rotating the boom, I can judge that my point of origin is not (0,0).
At this point I have no idea how to get the correct origin. Kindly teach me if you have idea on this.
Do you think the way I calculated for the true value of X and Y is still correct? Is my reference too far?
Thank you very much.

How to create a pdf with the correct size?
Hi there
How do I create a pdf with the correct size? I created several albums and ordered them. Now I want to backup the album and I know how to create a pdf, but when I choose A5 it's to big, when I create my own size it's not the size it should be. The original (made with iphoto) is a small size album 200x150mm. But when I create my own size (200x150) it shows some white borders.
Does anybody have some tips ore workarounds?

Iphoto 11 (9.4.2)Books are designed for and printed on 8.5 x 11 inch stock, US Letter size. You shouldn't have to select any size. While viewing the All Pages mode in the book Control-Click on the page and select Save Book as PDF from the contextual menu.
That will create a PDF that iPhoto uses to upload and print. Not all pages will be the same size as the dust jacket will be present in it's full size, 32.8 inches x 8.91 inches:
If you want a PDF that's designed for your own printing the type Command+P while viewing the All Pages window. In the first print window click on the PDF button. It will present you with a contextual menu where you should select Save as PDF. That will give you an 8.5 x 11 PDF file with all pages the same size.

How to create a circle from the centre?
Hi. I'm using PS CS3 and I want to create a perfectly round circle from the centre. How do you do this?
I know pressing shift while dragging makes it perfectly round. I've also read that pressing alt at the same time draws it from the centre, but it's not working, it just comes up with the eyedropper tool. Am I missing something or is there a different way to do it?
Thanks.Hi,
If you click and hold the mouse and then press the Alt key and drag it should work.
Also, after you start dragging, add the Shift key to constrain to a circle. -
How to create reports servers with the same name in two nodes in Reports
Greetings
We are migrating Oracle Application Server 10g (9.0.4) to a better hardware infrastructure with high availability. We want to provide 2 new Oracle Application Server 10g (9.0.4) in High availability and we want to avoid modify the existing forms and reports code, but the code is looking for a specific reports server name when calling reports, but I couldn't create the same reports server name in the both oas machines, I could create the reports server in only one node. I want to create a reports server with the same name in both nodes but it is not possible. I know that there is a procedure to do that in 10.1,2 (Note 437228.1, How to Create Two Reports Servers With the Same Name in the Same Subnet) but I couldn't find the equivalent procedure in 9.0.4.
Anybody kwows how to create a reports server with the same name in two nodes using 10g (9.0.4)
Thanks
Ramiro Ortiz.Hello.
I applied the patch 4092150 on my oas 9.0.4.2 and I modified my rwnetwork.conf file changing the port to 14022 by following the note "How to Create Two Reports Servers With the Same Name in the Same Subnet? [ID 437228.1]" but I am facing the same error rep-56040 "server already exists in the network".
When I run osfind command I get the following information (My reports server is senarep and I want to create it on SNMMBOGOAS10):
osfind: Found 2 agents at port 14000

How to: Create a Program with the rs232 Device -Magcard Reader Writer
Hi Guys!.
Im New in using VB.net 2010 express
and it is my first time to do a project with a device needed to incorporate with it.
I have a device Magnetic Card Reader writer and a i want to create a connection and UI
that interacts with the device alone without using the default application and process.start command.
the main problem i want to be solve is to perform the connection and commands on a single form by allowing the user to read and write the data on a single form.
what i want to do is to create a main form that executes the commands needed to activate the event or allows the user to use the device w/o using the software. with the use of text box and button, while the read executes automatically if the card is swipe
to it end fill out the focus textbox given.
i have here a document that discuss commands for the device and i think it is needed to successfully connect all the process from device to the system
can you help me to do this project? tnx.. :)Hi,
Welcome to MSDN.
I am afraid that this is not the proper forum for this issue, since each Magnetic Card Reader writer has its API for developers.
You could consider getting supports by connecting with the publisher of that Magnetic Card Reader writer which should have the sample about using its API.
In addition, I did a research, you could refer to
Build a .NET Class for Serial Device Communications with P/Invoke to get how to communicate with that serial device.
Thanks for your understanding.

How to create web applications with the LabVIEW web server
Wonderful Forum,
I've noticed that sometimes it can be tricky for LabVIEW users to learn how to create their own custom web clients using the LabVIEW web server. I created a LabVIEW web development community group and wrote some tutorials to teach the basics of creating web clients using HTML, Javascript, and AJAX. The idea is that LabVIEW users without any web background can quickly look at some tutorials and examples to get started on their own projects.

National InstrumentsHi Joey,
A great idea! I recently presented at a local user group meeting about my WebSockets API (see the links in my signature). I've uploaded the presentation and the demo code I gave to our UG here.
I think the barrier to entry is with needing to know the web languages (e.g. html/css/js) as well as writing your LabVIEW code. I have joined the group and look forward to seeing some interesting content on there! Certainly some demos of using AJAX to make requests to Web Services and do something with the data (e.g. display on a graph) would be a good place to start.

How to create a circle with text that is transparent
I am trying to achieve this affect. I want a black circle with text in it but where ever I place the circle the text needs to be transparent and you see through it.
Any help would be much appreciated.
I am using Illustrator CC 2014
ThanksI am using CS5.1 but the technique is the same, hope the info below will be of help.
1. Create circle
2. Type word - then select Type from the top menu and select Create Outlines (for ease of selection I colour the type)
3. Select shape and text with the (black arrow) selection tool.
4. Top menu - Window - scroll down to Pathfinder
5. Select Divide - then select shape and text again and select the top menu Object and scroll down to Ungroup.
6. Then select the red parts of the text and delete or another way is to select a part of the text with colour go to top menu and go to Select scroll down to Same and select Fill Colour this will select all the same colour you will want to delete instead of clicking on each part separately and then delete.
Then save the file as a eps or Ai file etc

How to create a CD with the WinXP OS OEM?
Hi all,
Recently I bought a Tecra A7 that has WinXP OEM preinstaled. My question is: has Toshiba any tool to create WinXP CD? If not, why so and how can I do it cleanly? I want my PC to make tests and I probably have to format it in future!
Thank's
PedroEldorado, thank's for your reply.
I can use ghost, yes, but I think I should not have to do it because it makes no sense! First, I bough a computer WITH the Operating System and I must assure that if something happens to my OS I can restore it, WHATEVER it happened; second, if I want to use Ghost, I have to get an unauthorized copy (because I don't have it) and I don't want to do it! As far as I know, the only thing that you can generate a CD copy is the Tools and Drivers CD.
Of course I could *make* the WinXp with the directories that exist in CD and some freeware. But I think I don't have to do it, it should be done. Do you understand what I mean?
I have the Restore CD, yes. And the short time I contact with it (only yesterday) I didn't see a way to create Win Xp image.
It was nice if someone from Toshiba answers my question.
Thank's.

How to create a FSV with the text groups in spabish and English
Hi gurus,
could you help me with a issue. I want to know where i can add the text in english in the groups of the fse2 , because i have tha configuration with spanish text but when i execute the f.01 with the language EN the system do not give text in English. So could you help me?
best regards!I just tried it with our FSV, system language is EN and i executed the report in DE. I could see german texts but not on the FS items.
I dont know, if that is possible because these are custom texts/input fields from you as compared to the system text converted to the required language on the report header and other layout fields
If you want the FS items to also show text in 2 languages, i recommend creating another FSV in the alternate language and using it. -
