HB_DirUnbuild

HB_DirUnbuild

Attempt to remove a directory

Syntax

      HB_DirUnbuild( <cDir> ) -> <lSuccess>

Argument

<cDir> : The name of the directory to delete

Returns

<lSuccess> : A logical value denotes either <cDir> removed or not

Description

This function attempt to remove the specified directory <cDir> and return .T. if deletion is successfull, else .F.

Note

<cDir> must be empty HB_DirUnbuild() look like a synonym of DirRemove() and HB_DirDelete(); difference is in return value.

Example

      PROC TstDirUnbld()
         LOCAL cDir := 'C:\temp\TstUnB'

         ? 'Is', CDir, 'exists ?    ', HB_DirExists( cDir )   // .T.
         ? 'Is', CDir, 'UnBuilded ? ', HB_DirUnbuild( cDir )  // .F. (*)
         ? 'Is', CDir, 'exists now ?', HB_DirExists( cDir )   // .F.

      RETU // TstDirUnbld()

      (*) observed that <cDir> not found after operation

HB_DirDelete

HB_DirDelete

Attempt to remove a directory

Syntax

      HB_DirDelete( <cDirectory> ) --> nError

Arguments

<cDirectory> The name of the directory to delete

Returns

<nError> 0 if directory was successfully removed, otherwise the number of the last DOS error.

Most probable error codes :

      Code Meaning
      ---- ----------------------------
        2  File ( directory ) not found
      145  Directory not empty

Description

This function attempt to remove the specified directory in <cDirectory>. If this function fails, it will return the last OS error code number. See FERROR() function for the description of the error.

Notes

. This function is file/folder names case sensitive

. <cDirectory> must be empty

. HB_DirDelete()is same as DirRemove() C5.3 function, but it’s always available, not just when HB_COMPAT_C53 is enabled.

Examples

      cDir := ".\backup"
      IF HB_DirDelete( cDir ) == 0
         ? "Remove of directory", cDir, "was successfull"
      ENDIF

HB_DirCreate

HB_DirCreate

Creates a directory

Syntax

      HB_DirCreate( <cNewDir>) --> <nSuccess>

Arguments

<cNewDir> : the name of the directory to be created, including an optional drive. If you do not specify a drive, the current one is used. The new directory can be specified relative to the current directory, or absolute, including a drive letter followed by a colon.

Return

<nSuccess> : zero on success, -1 if there is an argument error; Otherwise, HB_DirCreate() returns the DOS error code. HB_DirCreate() returns 0 if successful;

Description

HB_DirCreate() creates a specified directory. Note that first you must have sufficient rights to create a directory. To create nested subdirectories, you must create each subdirectory separately, starting from the top-level directory that you want to create (see example below.)

Note

HB_DirCreate() is equivalent to HB_DirBuild(), MakeDir() and DirMake()

Examples

      .  This example assumes that C:\TEST exists and uses HB_DirCreate()
         twice to create a nested subdirectory under it:

      HB_DirCreate("c:\test\one")    // Create top-most one
      nResult := HB_DirCreate("c:\test\one\two")
      IF nResult != 0
         ? "Cannot make directory, DOS error ", nResult
         BREAK
      ENDIF

      You may also use something like this:

      HB_DirCreate( ".\test" )

HB_DirBuild

HB_DirBuild

Creates a directory

Syntax

      HB_DirBuild( <cNewDir>) --> <nSuccess>

Arguments

<cNewDir> : the name of the directory to be created, including an optional drive. If you do not specify a drive, the current one is used. The new directory can be specified relative to the current directory, or absolute, including a drive letter followed by a colon.

Return

      IF nResult != 0
         ? "Cannot make directory, DOS error ", nResult
         BREAK

DirName

DirName

Returns the current directory name

Syntax

      DirName( [<cDrive>] ) --> <cCurDirName>

Argument

<cDrive> : Designates the drive for which the current directory is determined (a colon is unnecessary). The default is the current drive.

Return

<cCurDirName> : name of the current directory as a character string. The string does not include a drive letter.

Description

DirName() determines the current directory name on the selected drive. You can use this function to construct complete access paths.

Note

DirName() seem as a synonim of CurDir() and doesn’t support <cDrive> properly

Example

      ? '  ->', DirName(), CurDir()              //    -> \temp temp
      ?
      ? DirChange( 'C:\TEMP' )                   //           0
      ? DirChange( 'D:\TEMP' )                   //           0
      ? DirChange( 'E:\TEMP' )                   //           0
      ?
      ? 'C ->', DirName( 'C' ), CurDir( 'C' )    //  C -> \
      ? 'D ->', DirName( 'D' ), CurDir( 'D' )    //  D -> \
      ? 'E ->', DirName( 'E' ), CurDir( 'E' )    //  E -> \
      ?                                          //
      ? 'C:->', DirName( 'C:' ), CurDir( 'C:' )  //  C:-> \
      ? 'D:->', DirName( 'D:' ), CurDir( 'D:' )  //  D:-> \
      ? 'E:->', DirName( 'E:' ), CurDir( 'E:' )  //  E:-> \

DirMake

DirMake

Creates a directory

Syntax

      DirMake( <cNewDir>) --> <nSuccess>

Arguments

<cNewDir> : the name of the directory to be created, including an optional drive. If you do not specify a drive, the current one is used. The new directory can be specified relative to the current directory, or absolute, including a drive letter followed by a colon.

Return

<nSuccess> : zero on success, -1 if there is an argument error; Otherwise, DirMake() returns the DOS error code. DirMake() returns 0 if successful;

Description

DirMake() creates a specified directory. Note that first you must have sufficient rights to create a directory. To create nested subdirectories, you must create each subdirectory separately, starting from the top-level directory that you want to create (see example below.)

Note

              DirMake() is equivalent to HB_DirCreate(), MakeDir() and HB_DirBuild()

Examples

      .  This example assumes that C:\TEST exists and uses DirMake()
         twice to create a nested subdirectory under it:

      DirMake("c:\test\one")    // Create top-most one
      nResult := DirMake("c:\test\one\two")
      IF nResult != 0
         ? "Cannot make directory, DOS error ", nResult
         BREAK
      ENDIF

      You may also use something like this:

      DirMake( ".\test" )
