TwainController Methods |
The TwainController type exposes the following members.
Methods| Name | Description | |
|---|---|---|
 | CloseSource | Use this method to close the connection to the device. |
 | CloseSourceManager | Use to close the source manager and release Twain. |
| CreateTwainMemory | Returns a new TwainMemory class for the specified pointer. |
| Dispose | Closes any TWAIN connections and releases resources back to the system. |
 | Dispose(Boolean) | Closes any TWAIN connections and releases resources back to the system. |
| Equals | Determines whether the specified object is equal to the current object. (Inherited from Object.) |
| Finalize | Allow the TwainController to chance to clean up any resources before being collected by the garbage
collector. (Overrides ObjectFinalize.) |
| FreeTwainMemory | Release memory allocated for TWAIN. |
| GetCapabilityArray | Retrieves an array of values to the specified capability. |
| GetCapabilityTwainType | Returns the TWAIN type for the specified capability. |
| GetCapabilityType | Use this method to determine the .NET Type DotTwain expects for a specific capability.
|
| GetCapabilityValue(DeviceCapability, Boolean) | Reads a Boolean capability value. |
| GetCapabilityValue(DeviceCapability, RectangleF) | Reads a RectangleF capability value. |
| GetCapabilityValue(DeviceCapability, Int32) | Reads an Int32 capability value. |
| GetCapabilityValue(DeviceCapability, Single) | Reads a Single capability value. |
| GetCapabilityValue(DeviceCapability, String) | Reads a String capability value. |
| GetConditionCode | Returns the condition code from the source manager. |
| GetConditionCode(TwainIdentity) | Returns the condition code from the source device. |
| GetDefaultDevice | Returns the identity of the default system device. |
| GetHashCode | Serves as the default hash function. (Inherited from Object.) |
| GetPendingTransferCount | Use this method to get the number of pages waiting to be acquired, reset the pending count or to end the
current page. |
| GetTwainDevices | Returns an array of TwainIdentity classes; one for each Twain compatible device found on the
system. |
| GetType | Gets the Type of the current instance. (Inherited from Object.) |
| InitiateDataTransfer | Use this method to have DotTwain handle the data acquisition details. |
| MemberwiseClone | Creates a shallow copy of the current Object. (Inherited from Object.) |
| OpenSource | Opens a connection to the CurrentDevice. |
| OpenSource(TwainIdentity) | Opens a connection to the device passed in. |
| OpenSourceManager | Opens a connection to the TWAIN Source Manager. |
| ProcessEvent | This method will process the Message object retrieved from
PreFilterMessage to determine if the message should be handled by the device or passed along the
message loop. |
| ReadTwainContainerData(TwainContainer, TwainMemory) | Returns the value of a memory pointer retrieved from a device. |
| ReadTwainContainerData(TwainContainer, IntPtr) | Returns the value of a memory pointer retrieved from a device. |
| RegisterTwainCallback | Sets up a callback for TWAIN device messages instead of using the traditional message loop. This should only be called when using the TwainController directly; the Device object automatically handles the callback. The callback feature is only supported when using the TWAIN 2.0 Data Source Manager |
| ResetAllCapabilities | Call this method to reset all capabilities supported by the device. |
| ResetCapability | Resets a single capability to its startup value. |
| SendCommand(TwainTriplet, TwainIdentity, ITwainDataStructure) | Send a command to the TWAIN API |
| SendCommand(Int32, Int32, Int32, TwainIdentity, ITwainDataStructure) | Sends a command triplet that may not be contained in the TwainTriplet enumeration.
|
| SetCapabilityArray | Sets an array of values for a specific capability to the device. |
| SetCapabilityValue(DeviceCapability, Boolean) | Sets a capability to a Boolean value. |
| SetCapabilityValue(DeviceCapability, RectangleF) | Set a capability to a RectangleF value. |
| SetCapabilityValue(DeviceCapability, Int32) | Sets a capability to an Int32 value. |
| SetCapabilityValue(DeviceCapability, Single) | Sets a capability to a Single value. |
| SetCapabilityValue(DeviceCapability, String) | Sets a capability to a String value. |
| SetExtendedImageInfoOptions | Sets the extended image information id values that will be retrieved when acquiring data. |
| SetThreadUIControl | Sets the parent control used to invoke events from the TwainController. This method is
automatically called by the Device object when acquiring images. |
| ShowSelectSource | |
| ToString | Returns a string that represents the current object. (Inherited from Object.) |
