Search and rescue for mindstorms 2.0 (nx?)

Hi guys, sorry not too knowledgeable about this stuff but could someone tell me the logic behind creating a search and rescue robot? (robocup style)
Having trouble getting a robot to follow a black line, detect when a green square is discovered and change direction to go the direction of the green square.
If possible could some kind of 'pseudo' code it for me? I'm not using any coding just the block editor and am quite confused!
Sorry, hope that was clear enough to understand! thank you guys

Hello,
I'd like to recommend you to start developping your application based on simple examples, then when you get stuck with some specific issue you can share these questions here in the forums.
This because it would be easier and faster for participants to give you a feedback about something that you are currently doing.

How do I search and replace for invisibles in Pages 5.5.2?

Three related problems all involving search and replace for invisibles.
1. A block of text where all double returns need to become single returns.
2. A block of text where all returns need to be replaced with a single word space.
3. A block of text where all double word spaces to be replaced with a single word space.
Pages 09 could do all three this handily. How can these be done in Pages 5.5.2?
Appreciated.

Here are screenshot of my attempts to make reducing double returns to one. First up selection of a double return:
Copy to the clipboard. Do a Command-F. Here's the resulting dialogue:
I paste in the contents of the clipboard:
Note the Search field no longer has an empty slot selected. Something is clearly in there, but no instance of whatever is has been found. Nevertheless, I proceed to set up the Replace field by selecting a single return:
Copy that to the clipboard and paste into the Replace field:
Nothing to search for and therefore nothing to replace. Am now wondering what that little scoop to the right of the eyeglass icon might indicate. Clicking on it reveals this:
Definitely not "a solution that just works."

Global Search and Replace for Scrambled/Garbled Characters

So I exported a bunch (over 3000) contacts from my Outlook on Windows by using Outlook2Mac, and also tried just using a straight CSV export. But the Chinese characters came out all garbled, and I no longer have the use of that Windows machine anymore.
Here's an example:
Name: ∂¿¨¸™K (May Huang)
Job Title: ±M§·∏g≤z
Dept: ¿Á∑~≥B/ODM∑~∞»≥°
Company: ®Ù•ﬂ∞Íª⁄
Address:
§≠™—∂m§≠≈v§≠∏Ù15∏π
•x•_ø§
•x∆W
I figure I can slowly piece together most of it by doing lots of global search and replaces -- for instance, "•x∆W" should be "台灣" (Taiwan) -- and changing each characters I know one by one.
Problem is, I can't figure out how to do a find and replace! Can anyone help me out?
Thanks in advance!
PowerBook G4 17 Mac OS X (10.4.5)

But for the sake of getting a solution to the
original problem, I wasn't able to export the vCards
from AddressBook and then do what you said. For some
reason, I couldn't open the .vcf file in TextEdit;
kept telling me that the file wasn't encoded in
"Traditional Chinese (Windows, DOS)" format.
You need to use the Open dialogue in TextEdit and open the .vcf in something that it will accept. When you export the stuff from Address book, it indeed is not in Trad Chinese.
I don't have your stuff, so I can't be exactly sure, but it should work something like this. You export everything from Address Book. Use the Open dialogue of TextEdit to open the file, probably as UTF-8. Save as MacRoman. Open again as Trad Chinese (Windows). Save as UTF-8. Reimport. You may need to experiment to find what works right.

Xml search and replace for 'Session Variables' in column title view

Hi Experts,
I have around 10 reports where measure column titles are displayed based the session variable.
Below is the syntax I have used in the column title
@{biServer.variables['NQ_SESSION.VariableName']}
Now I would like to replace the above syntax with some static text. To do this, I am trying to use the xml search and replace feature in the catalog manager.
For some reason, catalog manager is unable to find the syntax in the xml file. I have tried using escape character also for the apostrophe by using &apos, but no luck.
Any pointers on how to replace the text?
Thanks

Using Analysis get the xml conversion for @{biServer.variables['NQ_SESSION.VariableName']} from Advanced tab's xml code
use this code to find in catalog manager, if you able to find then go for search and replace option.
I think this should work for you.

Search and index for child projects

Hello I have a merged RoboHelp 9 project. Is there a way I can setup the project so that when the user does a search, the child projects are searched as well as the master? Is there a way that I can used the Smart Index Wizard from the master project to produce an index which includes the child projects as well as the master. Thank you for any help you can provide.

Welcome to our community, Steven
Sorry for slowness, forums seem hit or miss today.
What you are describing is exactly how a merge should operate. All projects that are part of the merge should be properly searched and an Index would work across all projects. Because of this, I'm struggling to see a need to index everything from only the Master.
As you likely already know, the Smart Index Wizard simply scans topics and auto-maps them to keywords in whatever project you have open.
Sorry, but there is no way I'm aware of for the Smart Index Wizard to be used from the Master and coax it to index child projects. It's an interesting thing to consider and I would heartily encourage you to submit a Wish Form to ask for this functionality to appear in a future release. You do this using the Wish Form. (link to the Wish Form is in my sig)
Cheers... Rick

How to Search and Array for multiple occurrences of a value

Hi,
I am trying to search an array of doubles for a number and report the index location(s) of a number. I.e. -allow for repetition. Search and report all index[i] where the number is contained in the array. For example I have
double[] myInputArray = new double[5];
double[] myInputArray = { 1, 2, 3, 3, 5 }I know how to search through the array ONCE and return the first occurrence of a number:
public double GetIndexOf(double Number) {
 for (int i=0; i<myInputArray.length; i++) {
 if (myInputArray[i] == Number){
 return(i);
 return(-1);
}How do I expand this code to report multiple index[i] locations if the number reoccurs in the array like the number 3 does in my example array above?

The way the Java libraries do this type of operation (String.indexOf(), etc) is to specify the starting index along with what you want to find.
Changing your example slightly (notice how I fixed your naming and more importantly, your return type):
public int indexOf(double num) {
 return indexOf(num, 0);
public int indexOf(double num, int fromIndex) {
 for (int i=fromIndex; i<myInputArray.length; i++) {
 if (myInputArray[i] == num){
 return(i);
 return(-1);
//usage to get all indices:
for ( int index = -1; (index = indexOf(num, index+1)) != -1; ) {
 System.out.println(index);
}Note that due to how floating point numbers work, you may find doing this on doubles (or any other operation that uses == with double arguments) to give you unexpected results.

Search and replace for Unicode characters

Hello,
I have a function which searches and replaces characters on file. It works with ASCI sharacters, but not when the strings which needs to be replaced contains Unicode ('á', 'ā') etc. The source file is codding
utf8 .
$file = "file.txt"
$SearchReplace = @($file)
#Process files by performing a search and replace
foreach ($file in $SearchReplace)
#Select-Object -Skip 1 |
(Get-Content $file) |
Foreach-object { $_ -replace 'unicode_string' , ';' } |
out-file -encoding Unicode $file
How to get working the search (and replace) function with Unicode characters?
Thanks!

No. it does not. I have verified that script does not recognize the diacritic
('á',
'ā') characters when at all the operations with the files I have specified encoding utf-8/Unicode.

When I upgraded to Lion the ability to search and look for "today" as a search parameter is gone. How do I get that back?

When I search for a document on my mac or want to add an attachment in mail I always used the defaults on the left to narrow down what I was looking at. it had the option for Today, this week, last week and not sure what else. now that I have upgraded to Lion that is gone and I need it back. Help.

In List View the center column will do that on a right click.

Search and replacing a url...

I just ran across an issue last night, my hyperlinks added a space at the end of the url. Does anyone know how to do a search and replace for the hyperlink window? I ended up editing every one of them. It probably wouldn't be so bad but that is a lot of repetition that InDesign should be doing.
Edit: I should mention that I am using CS3 on Windows XP. I am thinking I hit a bug with the above, the spaces should not have been there.

The document was imported from word 97. Last night I deleted the text and reimported it as I updated a few of the links. (Yeah I know about linking the document) I also added a few directly in InDesign. All hyperlinks except 2 had a space after them, those 2 were imported. Which makes me believe the problem was not with the importing(placing) but perhaps a bug in InDesign. This document use to export to pdf just fine. One thing I had noticed was the paragraph mark on all but those two were marked as a hyperlink. Even though I did a search and replace on all the paragraph marks to remove the hyperlink, the space remained in the url. So I ended up double clicking on each hyperlink in the hyperlink window and manually removing the space at the end of each url.

Perform search and replace in a custom command?

Hello,
Does anyone know how to perform a search and replace for selected text in a custom command?
My specific dilemma is this: I have a large document containing [very poorly formatted] songs. For example:
Verse1 Verse1 Verse1 Verse1 Verse1
Verse1 Verse1 Verse1 Verse1 Verse1
Verse1 Verse1 Verse1 Verse1 Verse1
Chorus Chorus Chorus Chorus
Chorus Chorus Chorus Chorus
Chorus Chorus Chorus Chorus
Verse2 Verse2 Verse2 Verse2 Verse2
Verse2 Verse2 Verse2 Verse2 Verse2
Verse2 Verse2 Verse2 Verse2 Verse2
Verse3 Verse3 Verse3 Verse3 Verse3
Verse3 Verse3 Verse3 Verse3 Verse3
Verse3 Verse3 Verse3 Verse3 Verse3
I would like to be able to select all the text in a verse and run my custom command on it that would remove the "" and replace "" with " ".
Thanks,
Kelso

replaceAll method in String is available only from 1.4 onwards.
http://java.sun.com/j2se/1.4.1/docs/api/java/lang/String.html#replaceAll(java.lang.String, java.lang.String).
You could use a method to search and replace a String with another...
public String replace (String source, String search, String replace) {
 StringBuffer result = new StringBuffer();
 int start = 0;
 int index = 0;
 while ((index = source.indexOf(search, start)) >= 0) {
 result.append(source.substring(start, index));
 result.append(replace);
 start = index + search.length();
 result.append(source.substring(start));
 return result.toString();
}

Oh my gosh I had the EXACT same problem, and for ages I couldn't figure out how to fix it until today. Here's what I did:
First I went onto my computer, opened itunes, and un-installed tumblr, vine and kik. These were the apps I was having problems with (it said I had them on my phone but, like you, they didn't show).
Then I went to the itunes store, searched for each one, and it said I could update them so I did (just FYI: for tumblr a window popped up saying "please click ok to confirm you are 17 years or older", so I did that also)
When I went back to my phone and tried installing them again (still on my computer), it worked!
I hope this helps, because it was incredibly frustrating. Good luck!

I am trying to connect Garritan Personal Symphony to Logic Express and Garageband. A dialog box pops up and asks for plugin Garritan-P. Where do I find it and what do I do with it. I can't locate this plugin doing searches on any of the porgrams.

How do I search a spreadsheet for a list of URL's | then search those URL's for keywords | save the output? (Oh yeah..., and schedule it)

Fist, I should mention I am not a programmer but am eagerly learning powershell!
I am looking for an automated solution to accomplish what I am currently doing manually. I need a script that would combine the following:
Reach out to a list of websites (probably a loop of some sort since the list will come out of a spreadsheet which could contain 1 or 100 different sites)
Search each page for a specific word or words (not contained in the spreadsheet though that may make it more scalable)
Save the URL of the site(s) that contained the keywords to one text file (versus the multiple .html files I am creating today)
Have the output contain which words it found on which site.
If not overly complicated, I would like to schedule this to recur once a week.
A working script would be ideal, but even the resources that show me how to incorporate each element would suffice.
I have had success pulling down the full content of the listed pages and saving them to a directory, which requires manual intervention.
So far this works, but it's not scalable:
     Set-ExecutionPolicy RemoteSigned
     $web = New-Object Net.WebClient
     $web.DownloadString("http://sosomesite/54321.com") | Out-File "C:\savestuffhere\54321.html"
     $web.DownloadString("http://sosomesite/54321.com") | Out-File "C:\savestuffhere\65432.html"
     Get-ChildItem -Path "C:\savestuffhere\" -Include *.html -Recurse | Select-String -Pattern "Keyword 1"
In otherwords, I have to manually replace the "http://sosomesite/54321.com" and "C:\savestuffhere\54321.html" when the URL changes to .\65432.com and the output name to match. That works fine when it's a couple sites, but again,
is not scalable.
Then, to see if any of the saved file's contain the keyword(s), I have to search the directory for the keyword which I am using:
Get-ChildItem -Path "C:\savestuffhere\54321.html" -Include *.html -Recurse | Select-String -Pattern "Keyword 1"

Hi Sure-man,
Sorry for the delay reply.
To automatically Reach out to all urls, you can list all urls in a txt file "d:\urls.txt" like this:
http://sosomesite/54321.com
http://sosomesite/65432.com
Then please try the script below to save the URL of the site(s) that contained the keywords to one text file "d:\outputurls.txt":
$urls = get-content d:\urls.txt
foreach($url in $urls){
$results = $web.DownloadString("$url")
$matches = $results | Select-String -Pattern "keyword1","keyword2"
#Extract the text of the messages, which are contained in segments that look like keyword1 or keyword2.
if ($matches.Matches){
$Object = New-Object PSObject
$Object | add-member Noteproperty keyword $matches.Matches.value
$Object | add-member Noteproperty URL $url
$output+=$Object}
$output|Out-File d:\outputurls.txt
If you want to schduled this script in Task Scheduler once a week, please save the script above as .ps1 file, and follow this article:

I hope this helps.

New iTunes search help!: I'd like to just start typing in the upper right search and have the list update like it did in older iTunes versions. Now it has little suggestions of WHAT IM NOT LOOKING FOR!

Remember the days when you were looking for that metallica song... you kind of knew the name... so you start typing it in the search, and that BIG WELL of music would whittle down with every character typed? the search covered titles, artists, genres, ANYTHING that was displaying. I know a lot of folks HATED this dynamic, but let's face it, it worked, and it worked WELL. And Apple's had us all get used to that dynamic for over a DECADE.
I get that times need to move foreward, but they went WAYYYYYYY too far with how the simple search box works now(upper right one) ... The columns of Title, Album, Artist, are still there, but they drastically change the layout and presentation with everything you search for... and newsflash, NOT EVERY SONG BELONGS TO A GENRE OR ALBUM OR ARTIST....
I'm the kind of guy that doesnt allow itunes to attempt to copy eveything into hundreds of folders. I already have it all pretty well organized...Lots of my music are soundbytes that I just had in the main widow of iTunes. Sure they'd be buried in the thousands of other songs, but with a click of a key I could get to it... now iTunes ONLY seems to try searching things that are in albums, genres, labeled so specifically that I would have to take a month off JUST to start catalogging my music the way iTunes wants... Even THEN only showing me a small number of choices in the search bar .... like "Do you want these 4 songs you DIDNT search in the invisible queue next?" "Did you mean all this other sh*t that you DIDNT search for?" **** I used to be able to find almost ANY song with like 3 keystrokes. if I type in "Zelda" ... (looking for that obscure live Zelda acoustic I recorded with my phone that I dont have the band name to) It suggests EVERYTHING else BUT that song... whereas before it would just list the 20 or so ANYTHINGS I have loaded into itunes with that string of letters in it.
Anyone else seem to have this issue? Is the OLD easy to search buried in the furthest preference trenches to TRY to weed out old dogs such as myself, who were able to master the crappy UI iTunes has neglected to give a **** about in the past?

Please try the action I supplied in my post.
If you untick the search Entire library
Then type in your search term it will give the list of songs in the main window

I have set up two users, one for myself and one for children. The computer automatically logs in for the children with no password required. When the children go to spotlight and type in a search criteria all of my files show up. How do I prevent this?

Log in to your account, and move all your files to your home folder. No other users should be able to access them there and they won't show up with a Spotlight search.
Make sure your kids' account(s) do not have admin privileges.
