Read Key(String).vi and spaces

Hello all,
I am having some trouble with the Read Key(String).vi. One of the strings I am reading in ends in spaces. This vi seems to want to truncate any trailing spaces. I don't want it to do that. Is there anyway of modifing the vi to not truncate spaces? Or should I not allow spaces to be written?
Thanks in advance,
Glen

I haven't dug very far into the config file VIs but the easiest thing to do is to enclose all of your strings with quote marks ("). If you do that, key values with trailing spaces are read correctly.

Read key bug?

Hi Technical and Expert NI Labview.
I am not sure if the read key.vi carries bug.
See my simple attached
I am using Labview 7.1
When I run the program , it reads "media_assets lpmsg.ini" instead of "media_assets\helpmsg.ini"
What could be the problem?
Pls advise Thanks
Clement

Hi Clement
You only need raw strings if your string contains special characters like \. You can open the "Read Key (String).vi" and check what happens if you work with raw strings or not.

How can I read "Keys" from a Config File that have square brackets in them?

I'm using the "Read Key (String).vi" from the config.llb and I'm having a problem because the key names in my file have square brackets in them. I'm creating an VI to read certain pieces of the TestStand �StationGlobals.ini� file and array elements appear as %[0] = "blah blah blah". It looks like they're not getting recognized at all. Is there a way to handle this?

I was just looking at the code inside the configuration VIs and the way they work under V6 is that the Open VI actually reads the contents of the configuration file, parses it (in nice-platform independent G) and stores it in a fancy LV2-style global called the "Config Data Registry.vi". The routine that does the parsing is called "String to Config Data.vi". My gut reaction is that this code is going to be the same in your version because between sometime prior to V6 of LV, NI changed the location of a couple terminals on the low-level Match String function and it looks like when this code was originally written the terminals were in the old configuration.
In any case, if your square-bracket containing strings are getting lost, this is probib
ly where it's happening at. The other place to check is in the read VI itself. The V6 VI for reading the configuration registry is called "Config Data Get Key Value.vi". It's output is then further parsed by a function called "Parse Store String.vi" if the "read raw string?" input is set to False (the default position).
Given that all the code for these functions are written in LV, you should be able to fix your VIs to read the strings you have in the ini file now. Which IMHO is actually the way they should work.

ConfigFile Read Key (Path).vi BUG?

I want to Read a UNC Path from my Configuration File.
[Path]
UNC_Path=\\Hssvr01\5_Test_Data\17_Labview\2009
For this I use the LV2009 VI Read Key (Path).vi and as result I get:
H:\ssvr01\5_Test_Data_Labview\2009
When I set in the Configfile the UNC Path to:
UNC_Path=\\\\\Hssvr01\\5_Test_Data\\17_Labview\\2009
The result is:
\\Hssvr01\5_Test_Data\17_Labview\2009
This looks OK but I updatated from LV8.2.1 to LV2009 and in LV8.2.1 the variant with "UNC_Path=\\Hssvr01\5_Test_Data\17_Labview\2009" gives me as result "UNC_Path=\\\\\Hssvr01\\5_Test_Data\\17_Labview\\2009"
Why this have in LV2009 changed? Is this a Bug?
In the LV2009 help I found this:
http://zone.ni.com/reference/en-XX/help/371361F-01/glang/unc_filename_support_of_io/
Isn't this valid for Read Key (Path).vi?

Check towards the bottom of this help page (also available from within LabVIEW)
Quote:
"The Configuration File VIs can read and write raw or escaped string data. The VIs read and write raw data byte-for-byte, without converting the data to ASCII. In converted, or escaped, strings LabVIEW stores any non-displayable text characters in the configuration settings file with the equivalent hexadecimal escape codes, such as \0D for a carriage return. In addition, LabVIEW stores backslash characters in the configuration settings file as double backslashes, such as \\ for \. Set the read raw string? or write raw string? inputs of the Configuration File VIs to TRUE for raw data and to FALSE for escaped data."
All clear?

what key(s) do it type to change language from english to other? i am writing a story in dual languages. I was told to click command and space bar together but it is not working.

Command Spacebar opens Spotlight as you have found out. If you want to change languages you need to say what app you are using to write the story in, I'm guessing you are using Pages or MS Word. If that's the case
Pages: Open Inspector - Click the T tab - Click Language and change your language.
MS Word: Tools Menu - Language - Choose your language.

Read Key and Write Key not working as expected with paths on RT

The configuration file VIs Read Key (Path) and Write Key (Path) don't seem to work as expected (at least not as I was expecting them to) on an RT target.
When working on my WinXP PC with these two VIs, paths are translated to what looks like is supposed to be a device-independent format before being written to disk. The path C:\dir\file.txt becomes /C/dir/file.txt when writing and vice versa when reading. On my RT target, however, that same path is written to disk as C:\dir\file.txt, unchanged from the native format.
The translaton of a native path to and from the device-independent format appears to be the responsibility of Specific Path to Common Path and Common Path to Specific Path. These both use the App.TargetOS property to determine the operating system. In the case structure for these two VIs, however, there is no case for PharLap or RTX. (My RT hardware is runnng PharLap; I don't know enough about RTX to comment.) This means that the results of String to Path or Path to String are used without translating between the device-independent format to the native path format.
This isn't a problem if you create a configuration file on one machine and use it on that same machine. I noticed this only when tranferring a config file from my PC to the RT target, where the target would not open the file paths it loaded from the configuration file.
This occurs on 7.1.1 and 8.0. I don't have 8.20 to see if happens there, too.

In LV 8.2, this was fixed.
The problem is App.TargetOS returns "Pharlap" on RT systems, and "Pharlap" is handled by the default case ("invalid OS target") in LV 8.0. In LV 8.2 the default case is "Windows 95/NT", however. The reason you could write and read an .ini file on RT in LV 8.0 and earlier is because these two VIs (listed below) were both running the default case of "invalid OS target".
vi.lib\Utility\config.llb\Common Path to Specific Path.vi
vi.lib\Utility\config.llb\Specific Path to Common Path.vi
As you saw, this fails when you perform one operation in Pharlap but the other in Windows. You can fix this by modifying the two VIs listed above. Just go to the case structure and make "Windows 95/NT" the default case.

Firefox 3.6.11 does not respond on mouse, only Tab key and space bar

HW: Lenovo R61i.
OS: MS Win-XP PRO, ver 20002, SP3
Internet Explorer is diabled in:
Contol Panal|add/remove programs|add/remove windows components
All other programs responds om USB mouse or the little joy-stick between G, H and B-keys.
Removed FF, booted and reinstalled FF 3.6.11.
Mouse works a couple of cliks - then Tab key and Space bar is the only tool.
By the way - living in Norway, means No version og FF :)

Getting very tired of this problem which is becoming much more frequent. I love the FF browser, but lately after I have been on line for a while, the browser stops responding to mouse clicks and I have to use the task manager to shut the program down and then reopen it to get it to work. From what I've been reading in the forums, this is not an uncommon problem. I've done all the recommended fixes and nothing works. Please fix this!!

Failure to read multiline string with Read Key.vi

I converted 2D array into a spreadsheet string and attempetd to write it as a key value into a configuration file. This worked just fine. However, when I attempted to read this multiline string using Read Key.vi, I got just the first line in return (see two vi's attached).
As sufficient documentation on configuration file vi's is all but missing, could you please advise on their (undocumented) features? What do I miss?
Thank you.
Michael

I use Config files all the time. Much more user-friendly than the
Registry. They are a Microsoft thing really, rather than LabView, and
come from Windows 3.11. Each value is limited to one line, so when you
write a spreadsheet string with end-of-line characters in it, you're
effectively breaking the .inf file
The solution? Try putting a "Search and Replace String
" after your
"Array To Spreadsheet String". Wire "Replace All" with a TRUE constant,
and wire "Search String" with a string in "\" view and enter \r\n (or do
0A0D in Hex view) and then then wire Replace String with a ";"
Now your .inf file will look like:
[Array]
Data=1.0000,0.0000,0.0000;0.0000,2.0000,0.0000;0.0000,0.0000,3.0000;
When reading it, just reverse the search and replace strings above.
I hope this helps,
Andrew

Unable to map expose and spaces keys to function keys on unibody macbook

Hi all. I just bought a unibody macbook and wanted to add the spaces key to view all the windows in all spaces to the F5 key, and another expose key to F6. I went into the control panel under "expose and spaces" and "keyboard shortcuts" under "keyboard" and tried to set these keys. But it never actually accepts any of the settings I make. I put the settings to make them f5 and f6 but nothing happens when I press the keys. I know about the gestures and the hardcoded keys that are predefined on the macbook, but none of these allows me to use spaces to look at all the windows.
What's going on here, have they made it impossible to set your own keys for these things now? Is f5 and f6 just totally unusable now? Is there a workaround?
This is really annoying. Any suggestions?

haha, I just figured it out after I posted it. It's Function-F5 that it get's mapped to even though it still says only f5. I don't know why it doesn't just say that in the first freaking place, but whatever.
Does anyone know of a way to do this without having to use function-f5 and just mapping it to plain old f5? As far as I can see the key is just sitting there unused..

Wireless keyboard n key is putting a space and my space bar does not work

My wireless key board keys are not working ... my n key adds a space my space bar is = and my delete is arrow left... no clear pattern to the incorrect key strokes. I have gone into language and text and keyboard and it does not help. I also rebooted and removed batteries

m, n, and space are only one bit apart in the code they generate. It sounds like it might be a hardware problem in the keyboard.

How to design and implement an application that reads a string from the ...

How to design and implement an application that reads a string from the user and prints it one character per line???

This is so trivial that it barely deserves the words "design" or "application".
You can use java.util.Scanner to get user input from the command line.
You can use String.getChars to convert a String into an array of characters.
You can use a loop to get all the characters individually.
You can use System.out.println to print data on its own line.
Good luck on your homework.

How can i limit the user to enter only A to Z and space in JFormattedText

dear
i want to use JFormatedTextField in two manners
1.Limit the no of charecters.means in a text field only 20 charecters r allowed.
2.and also check the enterd charecter must be a to z and space not other chareters r allowed.
3.same for numbers means 0 to 9 and decimal.
how can i do by using the JFormated TextFilef.

Probably lacks in some cases but what the hell.

this.key = key;
public String[] getValues() {

TupleBiniding code:
public class CSVRecordTupleBinding extends TupleBinding {

int valuesSize = tupleInput.readInt();
String[] values = new String[valuesSize];
for(int i=0;i<valuesSize;i++)
values[i] = tupleInput.readString();
return new CSVRecord(key,values);

could you please advise ?.
Thanks,

Hi Srini,
I don't see anything obviously wrong with the code you posted, except perhaps that the setter, setValues, does not update valuesSize -- you really don't need the valuesSize field, you can use the array length instead.
There must be something wrong elsewhere in your program. Please post a complete test program, that has a main() and can be run with only the JE jar file, that demonstrates the problem.

Reading a String with dynamic format.

Hello,
I'm learning Java and I'm relatively new to the scene. I decided to make a small free utility with the hope that it will help somebody. The utility is a Game Server (Call of Duty 4) connector that will help Administrators to connect to the server and execute commands without the need of running the game.
I have made a progress so far by searching these (very useful) forums but I came across a point that I can't by pass.
The only way to learn "Who Is" from the server is the rcon command "status". Using this command the server returns you the current map and the players playing with all their information. This is the part of the code that I need help at:
public static void StatusReader(String StatusInput) throws IOException {
                 ArrayList line = new ArrayList();
                    BufferedReader br = new BufferedReader(new StringReader(StatusInput));
                   String s = null;
                   int l=0;
              dokimi = StatusInput.split("\n");
         //    for(int j=0;j<9;j++){
          //        int i=0;
          //        dokimi2 = new String[0][0];
          //        dokimi2[0][0] = dokimi[0];
          //        System.out.println(dokimi2[0][0]);
              System.arraycopy(dokimi, 0, dokimi2, 0, 1);
            for(int i=0;i<(dokimi.length/9);i++){
                    for(int j=0;j<9;j++){
                   dokimi2 = new String[i][j];
                   System.arraycopy(dokimi, 0, dokimi2[i][j], 0, 1);
                   System.out.println(dokimi2[i][j]);
         //     while ((s = br.readLine()) != null)
              //     line.add(s);
               // StatusOutput = new String[line.size()][];
              //     for (int i = 0; i < StatusOutput.length; i++) {
              //               s = (String) line.get(i);
                   //          StringTokenizer st = new StringTokenizer(s, "");
              //               String[] arr = new String[st.countTokens()];
//                       for (int j = 0; j < arr.length; j++)
//                               arr[j] = st.nextToken();
        //               StatusOutput[i] = arr;
           //          for (int i = 0; i < StatusOutput.length; i++) {
      //                    for (int j = 0; j < StatusOutput.length; j++)
//                         System.out.print(StatusOutput[i][j] + " ");
     //                    System.out.println();
}I've been messing a lot with the code. +_What I want to do is to read this string that the server is sending,split it, and then place it in a 2D Array that I will attach on a table._+ So far I've made the StringTokenizer method to be able to , kind of, sort that String and put it in an array. However I usually get outofbounds errors because not always the lines have the same length. This is an example of the format that the server sends after executing the "status" command:map: mp_crossfire

In addition some nicknames contain spaces something that makes me wonder how I can set the nicknames to belong to the same position of the array. Something that i know is that all nicknames end with "^7" which is the in-game colour definition. Any help would be much appreciated. Thanks in advance.

Hello DeltaGeek and thanks for your answer.
I have 2 questions for you since you mentioned what the real problem is. The first question is how can I join 2 cells that will contain the 2 parts of the nickname in case of a space? Can I just check if the cell number x,y contains "^7" and then just copy that cell the x,y-1? Ive tried that but then I also have to move the rest of the columns to y-1 as well. Any idea how to do that?
I was assuming you'd be processing the split string anyways, and not just tossing it into your 2-d structure. If you want to use .split(), yes. you would need to merge those cells into the original name. System.arrayCopy() would likely be useful for doing most of the heavy lifting.
Another option you have is to tokenize the string using Scanner. That would let you pull each column out of the string individually. You'll need to populate the array manually (instead of just using what .split() gives you), but allows you to change the token delimiter between pulls.
As for the junk lines, I can just check if they don't much the tokens number and then just not add them to the array I suppose, am I right or....?That's certainly one option. I don't know what's being given back to you, it may be important.

UDF to read a file name and use some of its contents to map fields in target.

I have a scenario where I need to take the month and year from the file name and map it to suitable fields in the target. Ex - filename_apr2014 from this i should be able to read the month and year and map it. How to do this? I tried the udf -
public String getFileName(Container container){
DynamicConfiguration conf = (DynamicConfiguration) container.getTransformationParameters().get(StreamTransformationConstants.DYNAMIC_CONFIGURATION);
DynamicConfiguration conf = (DynamicConfiguration) container.getTransformationParameters().get(StreamTransformationConstants.DYNAMIC_CONFIGURATION);
DynamicConfigurationKey key = DynamicConfigurationKey.create("http://sap.com/xi/XI/System/File","FileName");
String ourSourceFileName = conf.get(key);
return ourSourceFileName;
got this error while testing the mapping -
Runtime exception when processing target-field mapping /ns0:MT_<<>>_Output/I<<>>; root message: Exception:[java.lang.NullPointerException: while trying to invoke the method com.sap.aii.mapping.api.DynamicConfiguration.get(com.sap.aii.mapping.api.DynamicConfigurationKey) of a null object loaded from a local variable at slot 2] in class <<>> method getSourceFileName[com.sap.aii.mappingtool.tf7.rt.Context@5b04fc0f]
See error logs for details

Hi Satish - You declared "conf" twice.
DynamicConfiguration conf = (DynamicConfiguration) container.getTransformationParameters().get(StreamTransformationConstants.DYNAMIC_CONFIGURATION);
UDF -
String filename = "";
DynamicConfiguration conf = (DynamicConfiguration) container.getTransformationParameters().get(StreamTransformationConstants.DYNAMIC_CONFIGURATION);
DynamicConfigurationKey key = DynamicConfigurationKey.create( "http:/"+"/sap.com/xi/XI/System/File","FileName");
filename = conf.get(key);
return filename;
And did you define the variable slot 2 in any of your UDF's?
The above UDF return the filename and you should handle the sub string later..

Read Key(String).vi and spaces
