using strings with percent sign

I have a long text string that gets parsed as I create custom controls.  The question that I have is to have a percentage in this text string and flags sign is to jump.

First of all, I doubled the percentage sign who took my first error an unknown specifier.  Now, I'm getting it again, but later in my code.

String = "ringchoose 1 = Variable check 1-Var, Var 2 = 2, Var 3 = 3; ring: Variable Type compare-char = 1, = 2 int, float/double = 3, chain = 4; the value Format specifier: using %%d used if this value is returned in the string. See Help)-% v; ringoperation-less = 1, equal to = 2, Greater Than = 3, not equal to = 4; "value: value to compare.

string_args = malloc(strlen(string_arguments)+1);                                  sprintf(string_args,string_arguments); //errored here first time                                        token = strtok(string_args,";");
while (token != NULL) {                                           item_list=0;                                          arg_token = realloc(arg_token,strlen(token)+1);
                                            sprintf(arg_token,token);   //error here now
                                                        arg_ptr = strtok(arg_token,":");                                            if (strstr(arg_ptr,"ring") != NULL) {                                               arg_ptr = strtok(NULL,"-"); //should now hold title of ring                                             controlIDs[i] = NewCtrl(funcHandle,CTRL_RING,arg_ptr,50*(i+1)+offset,40);                                               SetCtrlAttribute(funcHandle,controlIDs[i],ATTR_WIDTH,200);
                                                while (arg_ptr != NULL) {
                                                    arg_ptr = strtok(NULL,"=");
                                                    if ((arg_ptr == NULL) || (strchr(arg_ptr,';') != NULL)) break;
                                                    value = atoi(strtok(NULL,",\0")); //holds value
                                            InsertListItem(funcHandle,controlIDs[i],-1,arg_ptr,value);
                                                                if (arg_ptr[0] == '*') {
                                                        GetNumListItems(funcHandle,controlIDs[i],&item_list);   //holds index-1 to set active
                                                    }
                                                }
}
//Rest of if/elses not supplied  since I know looping works

i++;
                                            sprintf(string_args,string_arguments);  //resets tokening
                                            token = strtok(string_args,";");
                                            for (int j = 0; j < i; j++) {
                                                token = strtok(NULL,";");
                                            }

It's almost as if the extra percentage signs stripped the first time and the second time I did of this chain, they mistake.

In the example that you have posted, it seems that you could use strcpy() instead of the sprintf() function. strcpy() would not seek to interpret the content of the string in the same way.

  • LabVIEW 8.5 problems using strings with MATLAB Script node

    I am having some problems that seem to be a bug that I can not understand how to solve using strings in the MATLAB script node.

    I have two subVIs that make some calculations and both include a variable called "errortext" is a string. The two subVIs do their calculations using the MATLAB script node, so all the outputs are defined in the script node.

    The first sub - VI outputs that string and a number. The string is sent to an indicator on the front panel. The number is sent to the second Subvi which performs some calculations more and then returns another string of the same name to an indicator on the front panel. This second string is different from the first (error different two messages should appear).

    I did have problems with this in the past until this morning. This morning, it seems that two of these channels are now somehow mystically connected to each other. The second string repeat that what the first channel said despite the fact that the first string is not be linked to the Subvi where lives the second string. The only link between the two is a calculated value of double which went from #1 to the Subvi #2 Subvi.

    I tried many things: I tried to rename the strings so that they do not have the same name. Initially, he would not let me and gave me an error saying that the renowned string was a undefined variable (which is ridiculous). After removing and replacing things, I finally managed to do so I would change the name, but now it displays nothing at all and even more I think it might still display a completely different another string in my code!

    I also tried to remove the channel indicator and replace it. Yet once, it wouldn't let me initially. I would like to highlight, press DELETE and nothing. Finally after replacing all the subVIs with them, I was able to remove the flags, but this did not help the problem.

    Any idea for these problems pecular is greatly appreciated!

    I totally understand what you did, you were talking about variables in your fist post, and it was not clear if you were referring to a variable you have defined in the Matlab code, or you try to call a variable indicator/control, where is often seen on this forum (and who isn't). That said, the crux of The Matlab Script communicates with Matlab via ActiveX, and when you use a command window opens small. This is the workspace of Matlab environment. A variable that you define in a Matlab Script node will be visible in the other, even if it's in another VI (see attached for an example, figure). This is because the script nodes are running in the same environment space. It seems to me that if this is what is happening.

  • find the percent with grep sign

    Hello. I know it must be simple, but I can't seem to find it: how to find the percent with grep sign? Or % or -% nor [%] seem to do.

    Thank you

    There is nothing in particular the % sign: you should be able to find it by using one of the three methods you have tried. Have a good overview of the control panel search/replace. Don't find it what domain contain only the %? No space lurking here? It is on a locked layer? You have a style of paragraph or character set in the Panel "Find format '?

  • Format of column with the percent sign (%)

    Y at - it shaped the column put percent signs (%)?

    Currently, one of the fields in the report shows a number, for example "3.75", but we must add the percent (%) sign, for example "3.75%".

    I found the following:
    * To view '$5 234,10', I use "FML999G999G999G999G990D00", these formats with a dollar sign ($) and two decimal places.
    * To display "-5,234.10", I can use "S999G999G999G999G990D00", these formats with the sign (+) or (-) and two decimal places.

    However, I can't find how to add the percent (%) sign...

  • Split a string using regexp_substr with consecutive delimiter

    I split a string with tubes as a delimiter. A string like this for example:

    "THIS |" EAST | ONE | EXAMPLE '

    If I do something like this:

    SELECT REGEXP_SUBSTR('THIS|IS|AN|EXAMPLE', '[^|]+', 1, 4) FROM DUAL
    

    I would get the word EXAMPLE

    But if the string is like this:

    "THIS |" EAST | ONE | EXAMPLE '

    With the above query, I always get EXAMPLE, but the word should be in the next position (5) because after IS, there should be an empty element

    Is it possible to change the regular expression to also get the empty element?

    Thanks in advance

    Well, the way I understand it, you get this behavior, because there is 'nothing' between the delimiters. so there is a field, so it does not display it don't think the regular expression.

    Try it with a space between the delimiters - works fine.

    So, with this in mind, the simplest solution might be something like that?

    regexp_substr (replace(c,'||','| |'), "[^ |]") +' 1, 4)

    [edited to avoid having a partial answer marked "correct"]

    As mentioned below by a few others, there are other solutions using regular expressions.

    The solution above does not work if more than 2 consecutive fields are empty, or if the first or last is empty.

    A simple tweak to the logic would help with this:

    RTrim (regexp_substr (replace (c,'|))) ',' |'), ' [^ |] +', 1, level))

    However, even if it has still some limitations compared to the solution of the full regular expression mentioned by Frank, below.

  • What happened to the tab with the sign + to create an empty tab?

    I recently upgraded to v3.6 through several versions of Firefox v8.01. There was once a small tab with a sign more at the end of the tab bar that allowed me to create a new empty tab. It seems to have disappeared somewhere beyond v4.0

    What happened and how I get it back? Yes I know I can activate the button of toolbar for a new tab, but have it at the end of the tab bar is more natural to use.

    Thanks for help

    Break the string of numbers in a table of numbers.  (Spreasheet String to Array).

    In a loop For, index with each issue of this table.  Use in the range and Coerce to see if it is in the range of numbers.  (You can put this in a loop For as auto good indexing through the ranges).  If it's in the range, then use subset replace table to activate the corresponding item in a real.  If this is not the case, do nothing.  Maintain the table of Boolean in a shift register.

    Repeat this step for each number in your table.

  • Why the continuous measurement and Logging in LabVIEW 2012 Project uses strings instead of Enums and orders from the queue?

    Hello!

    I noticed that the continuous measurement and a project in LabVIEW 2012 Logging using chains instead of enums and orders from the queue. I wonder if there is a good reason for it?

    Kind regards

    Anguel

    First, string vs enum debate is probably the version of LabVIEW vim vs emacs. There are good arguments on both sides, and I doubt that there is always a "winner".

    A brief summary of our reasoning for the current state of the project examples:

    1. We used enums for the state machine because it is self-contained. A state machine will never tell himself to enter a State, he does not know. Knowing (as the programmer) all possible States with the help of an enum allows you to enlist the compiler in order to help us avoid mistakes to change the time (because you can't quite out an enum and LabVIEW can be said if you are not covering all cases to a structure of the case, etc..).

      Enums provide greater protection and rigidity by ensuring all withdrew at the time of publishing. This is often the 'default' recommendation that we do.

    2. We used strings for messages in queue manager because the producer of message and the message handler could be independent processes that are reused or traded. Channels avoid the need for the compiler to be able to connect the orders and push this responsibility to the programmer. This allows you to develop some sub-components independently as long as you agree to a series of channel commands that you can manage - you need not to share a file 'messages.ctl' or 'states.ctl '. It is conceivable a loop of message management a message it does not, how you can decide to either silently ignore it or will trigger an error (as we do in the model). The strings make it also easier if you want to swap the queues of LabVIEW outside by a TCP implementation for network vacilitate or intra-Processuse communication where the other end may or may not be written in LabVIEW.

      Channels to provide more flexibility (that is, you can add new commands to an existing via plugins system, you can pass parameters as part of the string, etc.) at the expense of pushing her potential errors at run time and to put more responsibility on the programmer.

    3. The actor's gifts frame a 3rd option - using classes such as messages. For me, it combines many of the advantages of these two enumerations (strictly typed, change errors) and strings (flexible and scalable), but with the disadvantage of being somewhat less transparent (you understand OO, be comfortable to navigate through a multitude of screws, legacy of understanding, etc.).

    I don't know there are other reasons, others to the breast OR had or seen as we validated models and examples of projects in-house, but here are my reasons. We know that we can not design for each situation there - our goal is to get useful models against new users to make them aware of what well thought LabVIEW programs are similar to experienced users know their applications better and I hope they do not hesitate to change what we provide or create their own designs, when they feel it's necessary. (On a side note, please share what you come up with - a community of experts sharing models would be really useful to us all LabVIEW users).

  • Initialization of a string with a UTF-8 character

    It doesn't seem like it should be that hard, but I am trying to initialize a string with a UTF-8 character (specifically a degree after a few numbers symbol).

    I tried:

    Dim myString As String = new String ("\uc2b0", "UTF - 8");

    as well as a few permutations but did not have luck...

    Java strings are in Unicode, UTF - 8 is a way to represent these characters in a stream of bytes.

    Take a look at the following code, it might be useful: I suggest to put point break in the line add and take a look at the content of the two strings.

    No compiled code, could not work, I hope you get the idea...

    Char [] testchars = new char [] {'\u00B0', '\u0020'};
    String displayString = "undefined";
    Byte [] testBytes = new byte [] {(byte) (byte), 0xC2 0xB0, 0x20};
    String displayString2 = "no set2";
    try {}
    displayString = new String (testchars);
    displayString2 = new String(testBytes,"UTF-8");
    } catch (Exception e) {}
    }
    BasicEditField bef = new BasicEditField ("Test2:", displayString + ":" + displayString2);

  • I need assistance with the signing of the app

    So I made an android app and when I heard about the offer of playbook I went and reconditioned using package online Manager. I sent my app for review and I just got an email saying that my application has not been approved because it has not signed correctly. I am so confused, I need help.

    HM, strange. I used the tool to sign several apps (loading of Android applications on my PlayBook is such a pleasure), and it worked very well.

    Open your BAR with WinRar or WinZip file, there should be 2 folders inside. META-INF folder must contain a MANIFEST file, two files RDK and two files of the AUTHOR if the app is signed. If you don't see these files not try once more with the online tool, if you have doubts about the measures, just ask, we will try to help you.

  • ASA5505 IPSEC only with self-signed certificates

    Hi all

    I have little Cisco training and was assigned to a pilot project. We have cleaning of the ASA from another Department, but I do not have access to support. It is running ASA v9.1 and ASDM 7.1. If all goes well I'll be sent on training and we can buy a nice 5520.

    So I scoured the internet for a guide that is easy to do as my title says, but I'm having major trouble. I find a lot of outwardly signed with self-signed SSL VPN or VPN IPSEC with CERT support but I can't only get ASA self-signed IPSEC IKEv2 with certificate authentication. Also, to make it even worse, I have to provide the user with the software, the profile and the certificate in hand. No access to the web or download portal.

    If you know where I can get good installation guide for this type of use please by all means save me here. If this isn't possible, I'm cool with that, let me know.

    Thank you fo any help you can provide

    If the ASA uses a certificate issued by a certification authority that is in-store customer trust root CA, then the certificate of identity ASA didn't need to be imported by the customer.

    Which is why it's usually recommend to follow the path of using experienced public CA because they are alreay included in most modern browsers and so the client has no need to know how to import certificates etc.

    If you are using a local certification authority that is not in the store trusted CA of the customer to deliver your ASA certificate or identity certificates on the SAA signing root then you must take additional measures at the level of the customer.

    In the first case, you could import the CA certificate in the store root CA of the client trusted root. After that, all the certificates it has issued (the IE the ASA certificate of identity) would automatically be approved by the customer.

    On the second case, certificate of identity of the SAA is would have installed on the client because it (the ASA) basically as it's own root certification authority. Usually, I install them in the CA store root confidence of my client, but I guess that's technically not necessary, as long as the customer knows to trust this certificate.

    Hi guys,.

    When you type information in a form in the DC or Pro Player I can enter text with fields of text etc and then save, close and return later to change the form. However once I use the function "Fill & Sign" to sign the document, and then save, it locks the file and all other fields become editable. Is there a way around this to remove this feature where it becomes locked and instead allows me to change the form after a signature is applied and saved. All the security properties of the form are on 'admitted', there is no restriction. Even though the document is locked all the properties remain still as 'authorized '.

    The signing is FINAL.  You cannot sign a PDF paper advance. Complete and save, do not sign.
