paste

The paste command copies the contents of the clipboard into the workspace. Digital-video devices recognize this command.

To send this command, call the mciSendString function with the lpszCommand parameter set as follows.

_stprintf_s(
  lpszCommand, 
  TEXT("paste %s %s %s"), 
  lpszDeviceID, 
  lpszItem, 
  lpszFlags
); 

Parameters

lpszDeviceID

Identifier of an MCI device. This identifier or alias is assigned when the device is opened.

lpszItem

One or more of the following flags.

Value Meaning
at rectangle Specifies the location within the frame where the data is pasted. The upper left corner of the rectangle corresponds to the upper left corner of the added data. If the rectangle has a nonzero size in X or Y, the contents of the clipboard are scaled in those dimensions when they are pasted into the frame. If omitted, the rectangle defaults to the entire frame. If this flag is specified in "insert" mode (the default), any region outside the rectangle is painted a solid color.
audio stream stream Specifies the audio stream in the workspace affected by the command. If only one audio stream exists on the clipboard, the audio data is pasted into the designated stream. If more than one audio stream exists on the clipboard, the stream indicates the starting number for the stream sequences. If you use this flag and also want to paste video, you must also use the "video stream" flag. (If neither flag is specified, all audio and video streams are pasted and retain their original stream numbers.)
insert Specifies that the data is inserted into the workspace. Any data after the insertion point is moved forward in the workspace to make room. This is the default value.
overwrite Specifies that the data is copied into the workspace by writing over any existing data after the insertion point. The "insert" and "overwrite" flags affect whether frames are destroyed or moved during the paste operation, not how the data is pasted within each frame.
to position Specifies the position in the workspace at which the data is pasted. If omitted, it defaults to the current position.
video stream stream Specifies the video stream in the workspace affected by the command. If only one video stream exists on the clipboard, the video data is pasted into the designated stream. If more than one video stream exists on the clipboard, the stream indicates the starting number for the stream sequences. If you use this flag and also want to paste audio, you must also use the "audio stream" flag. (If neither flag is specified, all audio and video streams are pasted and retain their original stream numbers.)

lpszFlags

Can be "wait", "notify", "test", or a combination of these. For more information about these flags, see The Wait, Notify, and Test Flags.

Return Values

Returns zero if successful or an error otherwise.

Remarks

No signals are present in the data copied from the clipboard. The change becomes permanent only when the data is explicitly saved; however, playback acts as if the data has been added.

Requirements

  Windows NT/2000/XP: Included in Windows NT 3.1 and later.
  Windows 95/98/Me: Included in Windows 95 and later.
