How to build a library of string functions?
I want to create a set of my own special string functions. Trouble is I cannot create a class that extends String because it has been declared final. I want to be able to use the existing String functions as well as my own. Any ideas?
Thanks in advance.
Create a class that doesn't extend String. Use the String methods. You don't have to extend a class to use its methods. Example:public class LameUtility {
public static char getFirstCharacter(String s) {
return s.charAt(0);
}

Utility library error string function?
I've been working on an Error Handler library, culled mostly from these wonderful fora (Roberto!). I can't seem to find an error code string generator for the functions in the Utiltiy Library though (in particular, functions like RenameFile, CopyFile, GetDir, SetDir, MakeDir, all the file i/o functions).
Most of those make mention to negative error types with some plain text explanations. But there's no mention of a nice code-to-string converter function, as there is in other libraries. For instance, for the RS232 library, there is GetRS232ErrorString. For the Formatting & I/O library, there is GetFmtIOErrorString.
Am I not seeing it somewhere? Inside the Utility library, there is a multithreading error code function called CmtGetErrorMessage.
Solved!
Go to Solution.You're right: the Urility Library does not incorporate a function that translates error codes to a meaningful text. I suppose this is due to the fact that error codes partly overlap, so a unique function could not be used.
Just as an example, error -1 means File not found in almost all file I/O library functions, but it translates to No files found matching the search criteria in GetFirstFile () , to No more files in GetNextFiles () and Invalid Parameters in MakePathname ().
Another example: error -2 means GetFirstFile must be called before if returned by GetNextFile (), and Resulting pathname too long if returned by MakePathname ().
And this considering only File I/O section of the library!
While developing my own toolbox of utilities, I have created the following function, which I know is far from perfect and covers only file I/O functions:
char * CVIFUNC GetULibFileIOErrMsg (int error)
// Messages associated to error codes returned by functions in File Utilities class in Utility Library
switch (error) {
case 0: return "Success";
case -1: return "One of the path component not found";
case -2: return "Resulting pathname longer than 260 chars";
case -3: return "General I/O error occurred";
case -4: return "Insufficient memory to complete operation";
case -5: return "Invalid path";
case -6: return "Access denied";
case -7: return "Specified path is a directory, not a file";
case -8: return "Disk is full";
case -9: return "New file already exists";
default: return "Unknown error";
return NULL;
Proud to use LW/CVI from 3.1 on.

How to build a fixed-length string representing an integer
Hi,
I would like know how can I use the API to get a String representing an int with fixed length. I mean, I would like something similar to Integer.parseInt(), but I need to set the length of that String in such a way that, for instance, if I need the String to be 5 character long, and the int is 37, the String would be 00037
Thanks in advance and best regards,
Miguel ?ngelI wrote pad() methods in my string helper that can be used for this purpose.
In particular, you want to prepad with '0' to a length of 5:
com.Ostermiller.StringHelper.prePad(Integer.toString(37), 5, '0');

How to find out what are the functions supported by string class
Hi,
Can any one let me know how to find what are all the functions supported by the string class in standard(STL) library on solaris.
Regards,
Vignesh1. Any C++ textbook that covers the Standard Library will tell you about the standard string class. A good tutorial and reference for the entire Standard Library is "The C++ Standard Library" by Nicolai Josuttis, published by Addison Wesley.
2. WIth Sun C++, the command
man -s3C++ basic_string
provides documentation for the default libCstd version of the Standard Library.
3. You could look at the <string> header itself. I don't recommend that approach. -
How to deploy a single PBL (Build Runtime Library) in 64Bit
Hello There,
I am testing PB15 and create
two Project Files within the application. One Projectfile to compile a 32Bit Version and the other one to deploy a 64Bit version in P-Code. We are delivering today Patches in a Patch Library at the top of the library list (we are aware for the dependencies and know how to avoid the “Wrong Function Call” issue).
How can I create a Patch Library for 64Bit?
Today we just recompile the Patch.PBL two times and rename Patch.PBL -> Patch.PBD. But that did not work with 64Bit Project because I can’t choose the desired Platform (I am guessing it is always compiles in 32Bit).
There is an additional menu point “Build Runtime Library” which seems to have the settings / option similar to the Project settings. But there is the Platform the missing link either (see attached Picture).
So how can I get a single PBL compiled in 64Bit without deploying the whole Project?
BTW:
Compilation of the Whole app takes about 6 hours and results in full XCOPY deployment
of 730MB (in 64Bit), so we want wait that time or deliver so much files if a single
Patch.pbd of 500KB would be sufficient.
Regards
MarcoHi Marco,
You should try orcascript to build your patches. It is much cleaner and faster.
I setup a .dat file with the orcascript and then run it using a .bat file.
this is my batch file command: OrcaScr125 build.dat >buildlog.txt
Note that the orcascr command is version specific. I have NOT tried this yet with PB 15 32 or 64 bit.
this is what the build.dat would have in it. The liblist has to be your lib list, same with the main applicaiton info.
NOTE: i regen a function in the script in order to set a patch date that users can see. Also, note that i copy the patch.pbl to a build directory, build it, then copy the .pbd to various locations.
start session
file copy "patch.pbl" "build\patch.pbl"
set liblist "build\patch.pbl; ...."
set application "C:\main.pbl" "app"
regenerate "build\patch.pbl" "f_get_patch_date" "function"
build library "build\patch.pbl" "" pbd
file copy "build\patch.pbd" "patch.pbd"
file copy "patch.pbd" "..\patch.pbd"
end session

Hello,
does anyone know a tutorial to install the gd2 library on leopard server?
the tutorial from http://osx.topicdesk.com/ is not working properly.
Is it necessary to recompile php 5.2.4 which is shipped with leo server?
many questions here
chicoI am trying to setup GD with the default PHP build that comes preinstalled on Leopard, but I am unable to get it work correctly.
So far I have followed these instructions to get PHP5 working with with Apache2, this works fine and I am able to setup multiple virtual hosts for each of my websites and I have also downloaded and installed MySQL 5.0.45 which is now working fine with PHP the only problem is trying to get the extensions working.
I then tried following: Add the GD Extension to PHP5 on OS X Server 10.5.x guide to install GD2, which all seemed to work in the terminal, but after I restarted Apache and reloaded my phpinfo() there is still no mention of GD.
Any ideas why it isn't working (PS I have installed Xcode and X11SDK, from the Leopard DVD)
Heres my terminal log:

How to declare and initialize a STRING ARRAY (assign strings to array elements)
How to declare and initialize a STRING ARRAY (assign desired strings to elements of an array, for example "abc", "def", "ghi", "jkl", etc.) in LabVIEW? I saw a "string array" block in help, but could not find it in the function palette. Does a spreadsheet string have to be in a file (or can it be in a string constant block)? Thank you.
Hi,
you can do it in several ways:
1. Direct way: Create string array control on front panel and type strings in its elements
2. Programmatically 1: Create string array indicator (or local variable of control), right click on it in block diagram, select "Create constant" from drop down menu. The array constant will appear. Now type values in this constant's strings
3. Programmatically 1: Use "Build array", "Replace array subset", "Insert into array" or "Initialize array" functions from "Functions->Array" palette.
And of course you can combine all of these methods.
Good luck.

How to add a library (libSomeRandomlib.so) to a project....??
Ok, so I've been trying to get CERN's ROOT program/libraries to work in an xcode project for a while, but I'm running into one really weird error, and I think I may just not know how to add a library to a project correctly.
Suppose I create a new Xcode C++ command line tool project. I hit Build and go, and it gives me a nice little Hello World! in the console, just as it should. If I then click on the project in Groups & Files, go to Project>Add to Project..., and choose, say, libCint.so, from my root/lib directory, and click ok, then click Build & Go, I get an error in the console:
dyld: Library not loaded: @rpath/libCint.so
Referenced from: /Users/paulthompson/Documents/Programming/Build Products/Debug/LibraryIncludeTest
Reason: image not found
sharedlibrary apply-load-rules all
Data Formatters temporarily unavailable, will re-try after a 'continue'. (Cannot call into the loader at present, it is locked.)
My assumption is that either I'm missing a step in the process of adding a library, or else there is something jacked up with the libraries themselves. Anyone have any advice?
Thanks,
Paul
EDIT* Oh, I should mention that the actuall binary that gets built after adding the library WILL execute properly in the Finder, or from terminal, just not with the Build & Go, or Go commands from within xcode.

I honestly don't know much about @rpath. I found this page that explains it a bit more: http://blogs.sun.com/dipol/entry/dynamiclibraries_rpath_andmac
So, since I don't want to deploy with the environment variable set, I should ask, what IS the correct, MacOS X way to do it?
The best way to find that is to look at how Apple does it. They put frameworks in /System/Library/Frameworks and regular shared libraries in the standard places. You can do the same. Put your frameworks into /Library/Frameworks and your shared libraries into /usr/local-based paths.
If you want to create stand-alone executables that can be installed via drag-n-drop, you can put shared libraries inside the application bundle. If your shared libraries/frameworks are elsewhere, you will need some sort of installer to get them installed.
I've been sifting through Apple's developer documentation but I have yet to find a concise, straightforward explanation of how to add shared libraries. I'm horribly confused at this point. Is there a good tutorial available anywhere for both the general unix case of linking to dylibs and .so's, and the Mac specific case?
Hopefully someone else knows an answer for this one.
*EDIT* I do already have the variable defined both in ~/.MacOS/environment.plist and also in Xcode as an additional user variable.
I'm not sure about the whole RPATH thing. Setting environment.plist will define environment variables for use in the Finder, but that is really a hack. There are better ways to do it, but if you are porting some open-source programs, that may be the only way. You should be able to define those variables in Xcode. You have to selected the debug executable under "Exectuables" -
How do I process serial port strings as bits
In response to my commands, my instrument is sending bytes to my serial
port. In one instance, 2 bytes are received. I want to treat these 2 bytes
as a group of 16 bits.
The VISA and Compatibility Serial functions return these bytes from the
serial port to Labview clearly labelled a "string".
Everything I can find in the way of Labview functions and .vis don't want to
do bit twiddling, bit swapping, and bit dropping, with "string" data.
I thought "hex string to number" could be used here, but I can't find a way.
The 2 Bytes in question can be represented as hex, but the data are not the
ASCII codes for the hex representation of a binary number, they are the
binary number. This "hex string to number" seems to want ASCII c
odes.
You can feed a hex number typed into a "control" box wired into "hex string
to number" and you get a meaningful number. You can feed the 2 bytes from
the serial port into an "indicator" set to read in hex and you get a hex
number that is a correct representation. But that is Labview handing them
around to itself. I need to get my "hands" on them.
I can't feed those same bytes that show up as a correct hex representation
in an indicator into the "hex string to number" or anything else, so far,
and get a number that is useful for further processing.
I thought "variant to data", but I can't find enough reference material to
understand how to use it. A boolean array seems like a bit of a weird
approach, so I thought I'd ask before I looked into that.
I'm used to dealing directly with binary numbers on the processor stack, I
call them whatever I want, and turn them into anything I feel like.
I'm sure I'm staring the solution in the face, but I can't find any way to
persuade
Labview to treat this "string" data as 16 bits.
I've got the 16 bits, which is better than not having them, but I don't have
much hair left.duh, well I finally discovered the "Unflatten from String" function. A guy
just feeds in the bytes he's collected from his serial port that Labview
thinks are a "string", and out come lovely little unsigned 16 bit numbers,
or whatever other type of number he wants to turn the bytes into. And there
are great little bit twiddlers available after that, like "swap bytes", and
you can mask out bits with the logic operators, why this is fun. There's
nothing like being a moron...... fly me to the moon...................

It only stores your iPhone/iPad versions on your device, which is amazing. Why would you need anything else? It freed up around 8-10GB of space on my device which is amazing. But how does it work when you use it?
When you email it seems to ask you, when sending what size you want to send like it's always done. It gives you the original 2.4MB version. This works like I'd imagine and when I received the test email the photo was correct. In this case I assume it hits iCloud and sends it from there, not your actual device. (Like it doesn't re-download it to email it). Correct?
When posting to Facebook, does it do this same thing? Or is this something Facebook has to build into their iOS app in an update? Or does it just work? Correct?
When posting to Instagram, does it grab the right version. Obviously the phone optimized version should be fine, but when viewing on a Desktop version of Instagram at instagram.com, will it show the right version?
Sometimes I backup photos using Image Capture on the Mac. If I did that right now, would it only grab the iPhone versions? Obviously I can just test it but it'd be amazing if someone who knows these things could explain all of these use cases.
Do you need to be on
In closing it's more of how does this work? Does it work? Why wouldn't you want to use this feature if it saved space and made more sense? I guess I just would love some real clarity since not even the blogs are explaining how it works in every application.
In closing part 2. It does seem to work really well, it's just those fringe cases. I just viewed all my photos on https://beta.icloud.com/#photos and they're all there, easy download of the high res, delete, it deletes from my camera roll on my phone, it's amazing, it works, it's magic. Just tell me what issues there are with storing only low res iPhone on my device and if there are none, game on!

And of those 4.3GB of backup, my Photo Library is 1.4GB.
So my question is, how do I prevent my Photo Library from being backed up to the cloud, since I already have a backup of it everytime I connect to iPhoto and it copies all those photos to my mac?
I don't know, sorry. It's supposed to work alongside Photos & iCloud, so that photos are stored only once. When it doesn't work you have a couple of options as I see it –
Delete the old backups on iCloud to hopefully start over (I don't like deleting the only backup of anything).
Forget about iCloud backups & use iTunes to backup instead, it might not be suitable if you have no computer etc.
Buy more storage for iCloud.
I don't use iCloud backup, it bemuses me with issues like this, there is no easy way to resolve when it fails.
And one more question while we are at it...can I erase iphoto from my computer now that I have the new Photos app?
That is up to you. If you are happy you do not need it & have a backup of it go ahead & remove it. You can re-download it from the app store if it is already in your Mac App store account. -

I'm giving 3 input in Export parameter in BBP_PD_AVL_GETLIST and E_pdlist should contain data .
but e_pdlist is not getting data...any suggestion..

How to get sysnr value in a Function Module
Hi all,
I need to get the sysnr(system number) value of the R/3 system. I execute a RFC function module and need to get the value of sysnr of the system it executes in as a return parameter. Can somebody tell me how to get this value in the function module and return it.
Thanks and Regards,
PratikHello Pratik
The system number has to be defined in the RFC destination. Thus, select on your local system (where you call the RFC function module) the corresponding RFC destination from table <b>RFCDES</b>. In field RFCDES-RFCOPTIONS you will find a string like this:
H=<ip address>,S=21,R=N, ...
S=system number

Search and replace string function
Hello, I am using the "search and replace string" function and it does nt seem to work consistently for me. I am using it in a situation where I am taking an array of strings, converting this into a spreadsheet string then deleting all of the commas. Has anyone experienced the same behavior? I have searched through other posts and found other simular faults but none of the fixes worked for this. I can post the code it needed.
Thanks,
AndrewI agree that commas are often not desirable, especially if your software should also work in countries where comma is used as a decimal seperator.
Where are the commas coming from? Does (1) each element of the original array have one (or more), do you (2) use comma as seperator if you convert it to a spreadhseet string?
For (1), you might just strip out the comma for each element right in the loop. For case (2) you would simply use a different separator to begin with, of course.
Btw: you are abusing a WHILE loop as a FOR loop, because you have a fixed number of iterations. Please replace it with a FOR loop. If you use a FOR loop, LabVIEW can manage memory much more efficiently, because it can allocate the entire output array before the loop starts. For While loops, the total number of iterations is not known to the compiler. (Of course a real program would also stop the loop if an error occurs. In this case you would need to stay woth the WHILE loop. )
Do you have a simple example how the raw array elements look like. How many commas are there?
