ATTACHCONSOLE_ATTACHPARENTPROCESS

default value if not specifing a process ID

Declaration

public const uint ATTACHCONSOLE_ATTACHPARENTPROCESS = null

Field Value

Type	Description
System.UInt32

Methods

AllocConsole()

Allocates a new console for the calling process.

Declaration

public static bool AllocConsole()

Returns

Type	Description
System.Boolean

AttachConsole(UInt32)

Attaches the calling process to the console of the specified process. See AllocConsole function

Declaration

public static bool AttachConsole(uint dwProcessId)

Parameters

Type	Name	Description
System.UInt32	dwProcessId	The identifier of the process whose console is to be used. Or -1 to use the console of the parent of the current process.

Returns

Type	Description
System.Boolean

CloseHandle(IntPtr)

Closes an open object handle. See CloseHandle function The CloseHandle function closes handles to the following win32 objects:

Access token
Communications device
Console input
Console screen buffer
Event
File
File mapping
I/O completion port
Job
Mailslot
Memory resource notification
Mutex
Named pipe
Pipe
Process
Semaphore
Thread
Transaction
Waitable timer

Declaration

public static bool CloseHandle(IntPtr hObject)

Parameters

Type	Name	Description
IntPtr	hObject	A valid handle to an open object.

Returns

Type	Description
System.Boolean	true if it worked, use GetLastError if not

FreeLibrary(IntPtr)

Frees the loaded dynamic-link library (DLL) module and, if necessary, decrements its reference count. When the reference count reaches zero, the module is unloaded from the address space of the calling process and the handle is no longer valid. See FreeLibrary function

Declaration

public static bool FreeLibrary(IntPtr module)

Parameters

Type	Name	Description
IntPtr	module	IntPtr

Returns

Type	Description
System.Boolean	true if it worked, false if an error occured

GetModuleHandle(String)

Retrieves a module handle for the specified module. The module must have been loaded by the calling process. To avoid the race conditions described in the Remarks section, use the GetModuleHandleEx function. See GetModuleHandle function

Declaration

public static IntPtr GetModuleHandle(string lpModuleName)

Parameters

Type	Name	Description
System.String	lpModuleName	The name of the loaded module (either a .dll or .exe file). If the file name extension is omitted, the default library extension .dll is appended. The file name string can include a trailing point character (.) to indicate that the module name has no extension. The string does not have to specify a path. When specifying a path, be sure to use backslashes (), not forward slashes (/). The name is compared (case independently) to the names of modules currently mapped into the address space of the calling process. If this parameter is NULL, GetModuleHandle returns a handle to the file used to create the calling process (.exe file). The GetModuleHandle function does not retrieve handles for modules that were loaded using the LOAD_LIBRARY_AS_DATAFILE flag. For more information, see LoadLibraryEx.

Returns

Type	Description
IntPtr	If the function succeeds, the return value is a handle to the specified module.

GetProcessPath(Int32)

Method to get the process path

Declaration

public static string GetProcessPath(int processid)

Parameters

Type	Name	Description
System.Int32	processid

Returns

Type	Description
System.String	string

GetProductInfo(Int32, Int32, Int32, Int32, out WindowsProducts)

See GetProductInfo function

Declaration

public static bool GetProductInfo(int osMajorVersion, int osMinorVersion, int spMajorVersion, int spMinorVersion, out WindowsProducts edition)

Parameters

Type	Name	Description
System.Int32	osMajorVersion	The major version number of the operating system. The minimum value is 6. The combination of the dwOSMajorVersion, dwOSMinorVersion, dwSpMajorVersion, and dwSpMinorVersion parameters describes the maximum target operating system version for the application. For example, Windows Vista and Windows Server 2008 are version 6.0.0.0 and Windows 7 and Windows Server 2008 R2 are version 6.1.0.0.
System.Int32	osMinorVersion	The minor version number of the operating system. The minimum value is 0.
System.Int32	spMajorVersion	The major version number of the operating system service pack. The minimum value is 0.
System.Int32	spMinorVersion	The minor version number of the operating system service pack. The minimum value is 0.
WindowsProducts	edition	WindowsProducts

Returns

Type	Description
System.Boolean

GetVersionEx(ref OsVersionInfoEx)

See GetVersionEx function

Declaration

public static bool GetVersionEx(ref OsVersionInfoEx osVersionInfo)

Parameters

Type	Name	Description
OsVersionInfoEx	osVersionInfo	OsVersionInfoEx

Returns

Type	Description
System.Boolean	If the function fails, the return value is false. To get extended error information, call GetLastError.

GlobalAlloc(GlobalMemorySettings, UIntPtr)

Allocates the specified number of bytes from the heap. See GlobalAlloc function

Declaration

public static IntPtr GlobalAlloc(GlobalMemorySettings globalMemorySettings, UIntPtr bytes)

Parameters

Type	Name	Description
GlobalMemorySettings	globalMemorySettings	The memory allocation attributes. If zero is specified, the default is GMEM_FIXED. This parameter can be one or more of the following values, except for the incompatible combinations that are specifically noted.
UIntPtr	bytes	The number of bytes to allocate. If this parameter is zero and the uFlags parameter specifies GMEM_MOVEABLE, the function returns a handle to a memory object that is marked as discarded.

Returns

Type	Description
IntPtr	If the function succeeds, the return value is a handle to the newly allocated memory object. If the function fails, the return value is NULL. To get extended error information, call GetLastError.

GlobalLock(IntPtr)

Locks a global memory object and returns a pointer to the first byte of the object's memory block.

Declaration

public static IntPtr GlobalLock(IntPtr hMem)

Parameters

Type	Name	Description
IntPtr	hMem	IntPtr with a hGlobal, handle for a global memory blockk

Returns

Type	Description
IntPtr	IntPtr to the first byte of the global memory block

GlobalSize(IntPtr)

Retrieves the current size of the specified global memory object, in bytes.

Declaration

public static int GlobalSize(IntPtr hMem)

Parameters

Type	Name	Description
IntPtr	hMem	IntPtr with a hGlobal, handle for a global memory blockk

Returns

Type	Description
System.Int32	int with the size

GlobalUnlock(IntPtr)

Decrements the lock count associated with a memory object that was allocated with GMEM_MOVEABLE. This function has no effect on memory objects allocated with GMEM_FIXED. If the memory object is still locked after decrementing the lock count, the return value is a nonzero value. If the memory object is unlocked after decrementing the lock count, the function returns zero and GetLastError returns NO_ERROR. If the function fails, the return value is zero and GetLastError returns a value other than NO_ERROR.

Declaration

public static bool GlobalUnlock(IntPtr hMem)

Parameters

IntPtr	hMem	IntPtr with a hGlobal, handle for a global memory block

Returns

Type	Description

Returns

Type	Description
IntPtr	IntPtr for the module, IntPtr.Zero if this failed, use last error to see what went wrong
