Kernel Class

Description

COM API for calling some of Kernel32 functions.

Object model

Kernel - COM API for calling some of Kernel32 functions.

Process - Process object. Timing informations, priority settings and Ids. (CurrentProcess property, Current process.)

Thread - Thread object. Timing informations, priority settings and Ids. (PrimaryThread property, Primary thread of the process.)

Thread - Thread object. Timing informations, priority settings and Ids. (CurrentThread property, Current thread)

Process - Process object. Timing informations, priority settings and Ids. (Process property, The process of the thread.)

Methods

CloseHandle		Closes an open object handle.
CopyFile		The CopyFile method copies an existing file to a new file.
CreateProcess		Creates a new process and its primary thread. The new process executes the specified executable file.
DeleteFile		The DeleteFile method deletes an existing file.
MoveFile		The MoveFile method renames/moves an existing file or a directory (including all its children).
Sleep		Suspends the execution of the current thread for a specified interval.
SwitchToThread		Causes the calling thread to yield execution to another thread that is ready to run on the current processor. The operating system selects the thread to yield to.
WaitForSingleObject		returns when one of the following occurs: The specified object is in the signaled state . The time-out interval elapses.

Properties

CurrentDirectory		Retrieves or sets the current directory for the current process.
String, RW
CommandLine		The command-line string for the current process.
String, RO
ComputerName		Retrieves the computer name of the current systém.
String, RO
CurrentProcess		Current process.
Process, RO
CurrentThread		Current thread
Thread, RO
EnvironmentStrings		The environment block for the current process.
String, RO
EnvironmentVariables		Retrieves the value of the specified variable from the environment block of the calling process.
String, RO
hrCounter		Retrieves the current value of the high-resolution performance counter, if one exists.
double, RO
hrFrequency		Retrieves the frequency of the high-resolution performance counter, if one exists.
double, RO
hrTimeCounter		Retrieves the current value of the high-resolution performance counter, if one exists. The value of counter is converted to time (divided by hrFrequency).
double, RO
TempPath		Retrieves the path of the directory designated for temporary files.
String, RO
TickCount		The number of milliseconds that have elapsed since Windows was started.
Long, RO

ScriptUtils

Easy to use, hi-performance ASP file upload component with progress bar indicator. Let's you upload multiple files with size up to 2GB to a disk or database along with another form fields. Works with large posts, any character set (including unicode utf-8). Contains one-click multiple files/folders download with on-the-fly compression (Using BinaryWrite/BinaryRead).

      Hi-performance text file logging for ASP/VBScript/VBA applications. Lets you create daily/weekly/monthly log files with variable number of logged values and extra timing and performance info.
       Lets you work with safearray binary data in VBS/JS. It also enables conversion between binary and String data using several code pages. ZLib compress and uncompress functions. Lets you transfer files using compressed stream from a client to server using IE.
      This library also enables calling of some Kernel and Advapi functions (performance, timing, sleep, configuration ...) and enables native work with INI files.
