TwainMemory Methods |
The TwainMemory type exposes the following members.
Methods| Name | Description | |
|---|---|---|
  | Allocate | Call this method to allocate memory for this object. If memory has already been allocated, it will be
released before allocation new memory. |
| Copy(Byte, IntPtr) | Copies data from a pointer into a byte array. |
| Copy(IntPtr, Byte) | Copies a byte array into a pointer. |
| Copy(IntPtr, IntPtr, Int32) | Copies memory from one pointer to another. |
| Create | Returns a new TwainMemory object with no memory allocated. |
| Create(IntPtr) | Creates a new TwainMemory object for a pointer returned from TWAIN. |
| Dispose | Releases the memory used by the object. |
| Equals | Determines whether the specified object is equal to the current object. (Inherited from Object.) |
 | Finalize | Called by .NET when the object is being destroyed. (Overrides ObjectFinalize.) |

position. |

position. |

| ReadStructure(Type) | Reads a structure from the current Position and advances the position by the
structure memory size. |
| ReadStructure(Type, Int64) | Reads a structure from the specified memory offset. |
| ReadTwainMemory | Reads a TW_HANDLE from the current Position and advances the
position. |
| ReadTwainMemory(Int64) | Reads a TW_HANDLE from the specified memory offset. |
| ReadUInt16 | Reads a TW_UINT16 from the current Position and advances the
position. |
| ReadUInt16(Int64) | Reads a TW_UINT16 from the specified memory offset. |
| ReadUInt32 | Reads a TW_UINT32 from the current Position and advances the
position. |
| ReadUInt32(Int64) | Reads a TW_UINT32 from the specified memory offset. |
| ReadUInt8 | Reads a TW_UINT8 from the current Position. |
| ReadUInt8(Int64) | Reads a TW_UINT8 from the specified offset. |
| ToString | Returns a string that represents the current object. (Inherited from Object.) |
| Unlock | Unlocks the moveable memory when finished reading or writing. |
| Write(Byte) | Writes a byte array into the memory at the current Position and advances the
position. |
| Write(Byte, Int64) | Writes a byte array into the memory at the specified memory offset. |
| WriteBoolean(Boolean) | Writes a TW_BOOL into the memory at the current Position and
advances the position. |

advances the position. |
| WriteInt32(Int32, Int64) | Writes a TW_INT32 to memory at the specified memory offset. |
| WriteInt8(SByte) | Writes a TW_INT8 to the memory at the current Position.
|
