DirTree Unicode C++ Reference Documentation

CkDirTreeW

Current Version: 10.1.2

API for iterating over the files and sub-directories in a directory tree. The intent of this class is to provide a simplified, non-recursive way to iterate over an entire directory tree.

Object Creation

// Local variable on the stack
CkDirTreeW obj;

// Dynamically allocate/delete
CkDirTreeW *pObj = new CkDirTreeW();
// ...
delete pObj;

Properties

BaseDir
void get_BaseDir(CkString &str);
const wchar_t *baseDir(void);
void put_BaseDir(const wchar_t *str);

Begin iterating from this directory.

top
DebugLogFilePath
void get_DebugLogFilePath(CkString &str);
const wchar_t *debugLogFilePath(void);
void put_DebugLogFilePath(const wchar_t *str);

If set to a file path, this property logs the LastErrorText of each Chilkat method or property call to the specified file. This logging helps identify the context and history of Chilkat calls leading up to any crash or hang, aiding in debugging.

Enabling the VerboseLogging property provides more detailed information. This property is mainly used for debugging rare instances where a Chilkat method call causes a hang or crash, which should generally not happen.

Possible causes of hangs include:

  • A timeout property set to 0, indicating an infinite timeout.
  • A hang occurring within an event callback in the application code.
  • An internal bug in the Chilkat code causing the hang.

More Information and Examples
top
DoneIterating
bool get_DoneIterating(void);

Set to true when the last file or sub-directory has been iterated.

top
FileSize32
int get_FileSize32(void);

The file size of the current file in the iteration. (0 if it is a directory.)

top
FileSize64
__int64 get_FileSize64(void);

The file size as a 64-bit integer of the current file in the iteration. (0 if it is a directory.)

top
FileSizeStr
void get_FileSizeStr(CkString &str);
const wchar_t *fileSizeStr(void);
Introduced in version 9.5.0.88

The file size of the current file in the iteration as a decimal string. (0 if it is a directory.)

top
FullPath
void get_FullPath(CkString &str);
const wchar_t *fullPath(void);

The absolute directory path of the current file or sub-directory.

top
FullUncPath
void get_FullUncPath(CkString &str);
const wchar_t *fullUncPath(void);

The absolute UNC directory path of the current file or sub-directory.

top
IsDirectory
bool get_IsDirectory(void);

true if the current position is a sub-directory, false if it is a file.

top
LastErrorHtml
void get_LastErrorHtml(CkString &str);
const wchar_t *lastErrorHtml(void);

Provides HTML-formatted information about the last called method or property. If a method call fails or behaves unexpectedly, check this property for details. Note that information is available regardless of the method call's success.

top
LastErrorText
void get_LastErrorText(CkString &str);
const wchar_t *lastErrorText(void);

Provides plain text information about the last called method or property. If a method call fails or behaves unexpectedly, check this property for details. Note that information is available regardless of the method call's success.

top
LastErrorXml
void get_LastErrorXml(CkString &str);
const wchar_t *lastErrorXml(void);

Provides XML-formatted information about the last called method or property. If a method call fails or behaves unexpectedly, check this property for details. Note that information is available regardless of the method call's success.

top
LastMethodSuccess
bool get_LastMethodSuccess(void);
void put_LastMethodSuccess(bool newVal);

Indicates the success or failure of the most recent method call: true means success, false means failure. This property remains unchanged by property setters or getters. This method is present to address challenges in checking for null or Nothing returns in certain programming languages.

top
Recurse
bool get_Recurse(void);
void put_Recurse(bool newVal);

If true, the iteration will be recursive. If false the iteration is non-recursive. The default value is true.

top
RelativePath
void get_RelativePath(CkString &str);
const wchar_t *relativePath(void);

The relative directory path of the current file or sub-directory. (Relative to the BaseDir)

top
VerboseLogging
bool get_VerboseLogging(void);
void put_VerboseLogging(bool newVal);

If set to true, then the contents of LastErrorText (or LastErrorXml, or LastErrorHtml) may contain more verbose information. The default value is false. Verbose logging should only be used for debugging. The potentially large quantity of logged information may adversely affect peformance.

top
Version
void get_Version(CkString &str);
const wchar_t *version(void);

Version of the component/library, such as "10.1.0"

Methods

AdvancePosition
bool AdvancePosition(void);

Advances the current position in the directory tree traversal to the next file or sub-directory.

Important: If AdvancePosition returns false, it can be an error, or it could be that there are no more files and directories. To distinguish between the two cases, examine the DoneIterating property. If DoneIterating is true, then the false return value is not an error, but instead indicates that the end has been reached.

Returns true for success, false for failure.

top
BeginIterate
bool BeginIterate(void);

Begins a directory tree traversal. After calling this method, the various property values such as Fullpath, FileSize32, etc. can be retrieved for the 1st file / sub-directory in the traversal.

Important: If BeginIterate returns false, it can be an error, or it could be that there are 0 files and directories. To distinguish between the two cases, examine the DoneIterating property. If DoneIterating is true, then the false return value is not an error, but instead indicates 0 files/directories.

Returns true for success, false for failure.
