    I wish to replace spaces with underscores in a sting

    Hello experts
    maybe this is simple for you,

    I have the following function.

    void replacestring() {

    quality = quality->Replace(" ", "_");

    }

    I wish to replace spaces with underscores in the string "quality"

    When I compile I get the error message:

    config_files.c: In function ‘replacestring’:
    config_files.c:79: error: request for member ‘Replace’ in something not a structure or union

    Here is the code,

    config_files..c

    There is no 'replacestring' in the file you posted.
    Post a minimum example here that reproduces the problem. Do not attach files, post the code using code tags.

    Re: I wish to replace spaces with underscores in a sting

    I found the solution and am posting here for other people if they have the same problem, I needed to replace spaces with underscores, the program uses a gtkcombo box, where you can enter, a name for the mount point of darkice, and it does not like spaces.

    here is the code,

    Code:
    quality = (g_strdelimit (quality, " ", '_'));
    Thankyou for your time to reply to me, so I have spent my time to submit the solution, for others to see.

    Re: I wish to replace spaces with underscores in a sting

    What's the problem? Just write a loop that looks at each char in quality and if it's a space, change it to an _

    Red face Solved, I wish to replace spaces with underscores in a string

    The code that I have submitted on this thread is a single function "darkice_config_store"

    so when I used.

    Code:
    quality = (g_strdelimit (quality, " ", '_'));
    then the above code became part of the "darkice_config_store" function.

    When the start button is pushed on the darksnow gui then this function is activated, this function writes the config files for darkice.

    Unfortunately the code,
    Code:
    quality = (g_strdelimit (quality, " ", '_'));
    would back feed the text with "spaces replaced with underscores to the gtkcombo box",

    so I tried
    Code:
    strcpy(name2, quality)
    quality = (g_strdelimit (quality, " ", '_'));
    But the code
    Code:
    strcpy(name2, quality)
    kept crashing the gui and doing weird stuff, like if I enter lots of text and pushed start on the gui, it would crash and burn.

    after spending all night on this and experimenting with varies String Utility Functions from http://www.gtk.org/api/2.6/glib/glib...Functions.html



    I found the following code worked perfect.

    Code:
    name2 = g_strdup (quality);
    name2 = g_strdelimit (name2, " ", '_');
    So the string "name2" has the spaces replaced with under scores and the string "quality" is left with spaces,

    Now I can use the string "quality" in the places of the darkice config file where spaces are allowed, like the stream name.



    so now the complete code looks like this,

    Code:
    #include <stdio.h>
    #include <unistd.h>
    #include <stdlib.h>
    #include <string.h>
    #include <libintl.h>
    
    #ifndef __GTK_H__
    #include <gtk/gtk.h>
    #endif
    
    
    #ifndef __GLOBAL_H__
    #include "global.h"
    #endif
    
    #ifndef __CONSTANTS_H__
    #include "constants.h"
    #endif
    
    #ifndef __CONFIG_FILES_H__
    #include "config_files.h"
    #endif

    All of that just to replace spaces with an underscore???

    This is no more than 3 or 4 lines of code:
    Code:
    #include <string.h>
    #include <stdio.h>
    
    /* assume pString is null terminated and is not NULL */
    void ReplaceChars(char *pString, char origChar, char replaceChar)
    {
        while (*pString )
        {
            if ( *pString == origChar )
                 *pString = replaceChar;
           ++pString;
        }
    }
    
    int main()
    {
       char str[] = "This is a test";
       ReplaceChars( str, ' ', '_');
       printf( "%s", str );
    }
    I don't know what that stuff is that you posted, but it sure isn't what someone reading this thread would expect to be the solution.

    Red face Re: I wish to replace spaces with underscores in a sting

    this was my solution

    Code:
    name2 = g_strdup (quality);
    name2 = g_strdelimit (name2, " ", '_');
    all of 2 lines

    I included all of the code of the file I was working on, this was all I needed to add to my existing code which I had included in my post, since I was using GTK, in my code I decided to use string utility functions from glib. GLib is kind of an "objects for C" have a look at .http://www.gtk.org/api/2.6/glib/glib...Functions.html

    Thankyou for the function,

    kind regards

    I used standard 'C'. I have no idea what g_strdup() or g_strdelimit() are supposed to do, and neither would anyone else looking for a simple, standard solution. As long as the compiler is standard, my solution works regardless of compiler brand, compiler version, operating system, etc.

    Second, if g_strdup() is supposed to be some sort of a clone of the standard strdup() function, who cleans up that memory that was allocated? If that is the case where g_strdup() is the same as strdup(), then all you did was go from the frying pan into the fire by introducing a memory leak (or a potential for memory leaks).

    Thumbs up Re: I wish to replace spaces with underscores in a sting

    I must say truthfully I like your solution the best, and am most grateful for the time you spend explaining this stuff to me.

    can I output the result to a different string with your solution like;


    Code:
    #include <string.h>
    #include <stdio.h>
    
    /* assume pString is null terminated and is not NULL */
    void ReplaceChars(char *pString, char origChar, char replaceChar)
    {
        while (*pString )
        {
            if ( *pString == origChar )
                 *pString = replaceChar;
           ++pString;
        }
    }
    
    int main()
    {
       char str1[] = "This is a test";
       char str2;
       ReplaceChars( str1, ' ', '_');
       printf( "%s", str2 );
    }
    If so I will try your solution, thank you for sharing your knowledge.

    Most
    kind
    Regards

    Re: I wish to replace spaces with underscores in a sting

    You can simply pass the second string to the function as well:
    Code:
    #include <string.h>
    #include <stdio.h>
    
    /* assume pString is null terminated and is not NULL */
    void ReplaceChars(char *dstString, const char *srcString, char origChar, char replaceChar)
    {
        while (*srcString )
        {
            if ( *srcString == origChar )
                 *dstString = replaceChar;
            else
                *dstString = *srcString;
           ++srcString, ++dstString;
        }
        *dstString ='\0'; // make sure dstString is null-terminated
    }
    
    int main()
    {
       char str1[] = "This is a test";
       char str2[20]; // this value of 20 is completely arbitrary, but you must make sure that it is large enough to hold str1.
                           // You could as well malloc the space like so: char *str2 = malloc(20);
                           // but then you have to make sure you call free(str2)  when you are done with it to avoid a memory leak
       ReplaceChars( str1, ' ', '_');
       printf( "%s", str2 );
    }
    HTH,
    Richard
