Process 50 files in one folder a file at a time thru a dialog editbox using VC++ 6.0

Posted on 2002-03-12
Last Modified: 2010-04-01
I wrote a program to process a file at a time thru the edit box by selecting the file from the folder.  Now I need to modify the program so that I can process up to 60 files in a directory and run them thru the program that I wrote using VC++ 6.0 or by using wildcards for the file names.  Is there a way that I can do this? and if there is could your provide the sample code to do this?

What type of program do you write? (Dialog based, Doc/View, Console)

>>Is there a way that I can do this?

>>and if there is could your provide the sample code to do

What method do you prefer?  Do you want the user to select the files from a Common dialog?
Or do you want the wildcard approach?

You can use _findfirst, _findnext ...

* FFIND.C: This program uses the 32-bit _find functions to print
 * a list of all files (and their attributes) with a .C extension
 * in the current directory.

#include <stdio.h>
#include <io.h>
#include <time.h>

void main( void )
    struct _finddata_t c_file;
    long hFile;

    /* Find first .c file in current directory */
    if( (hFile = _findfirst( "*.c", &c_file )) == -1L )
       printf( "No *.c files in current directory!\n" );
            printf( "Listing of .c files\n\n" );
            printf( "\nRDO HID SYS ARC  FILE         DATE %25c SIZE\n", ' ' );
            printf( "--- --- --- ---  ----         ---- %25c ----\n", ' ' );
            printf( ( c_file.attrib & _A_RDONLY ) ? " Y  " : " N  " );
            printf( ( c_file.attrib & _A_SYSTEM ) ? " Y  " : " N  " );
            printf( ( c_file.attrib & _A_HIDDEN ) ? " Y  " : " N  " );
            printf( ( c_file.attrib & _A_ARCH )   ? " Y  " : " N  " );
            printf( " %-12s %.24s  %9ld\n",
     , ctime( &( c_file.time_write ) ), c_file.size );

            /* Find the rest of the .c files */
            while( _findnext( hFile, &c_file ) == 0 )
                printf( ( c_file.attrib & _A_RDONLY ) ? " Y  " : " N  " );
                printf( ( c_file.attrib & _A_SYSTEM ) ? " Y  " : " N  " );
                printf( ( c_file.attrib & _A_HIDDEN ) ? " Y  " : " N  " );
                printf( ( c_file.attrib & _A_ARCH )   ? " Y  " : " N  " );
                printf( " %-12s %.24s  %9ld\n",
         , ctime( &( c_file.time_write ) ), c_file.size );

       _findclose( hFile );

WIN32_FIND_DATA filedata;
char *filename;
HANDLE handle=FindFirstFile("*.txt",&filedata);
if handle{
    filename = filedata.cFileName;
    //call your processing routine for filename here
    BOOL ret=FindNextFile(handle,&filedata);

It is a a Dialog based program and I would rather use the wildcard approach by entering the directory in the edit box ie...   "c:\morethings\jackson\*.050"

that way it can go to that directory and process all the files in it that match the .050 extension.

Use a common dialog as Axter suggested. With the Common dialog you can apply the filter where only files with a specific extension will be shown in the File Open Dialog that is displayed.

This way users can choose from only files with the .050 extension you specify.

Have a look at the CFileDialog class in the MSDN docs.
