(Open Clipboard)
| Mnemonic: | (OpenClipboard) |
|
Discussion: | This mnemonic was added (along with CloseClipboard) to solve the problem where the clipboard may be unavailable because it is in use by another program (the clipboard can be opened by only one program at a time). If the clipboard was already in use the other clipboard functions would fail. Using this mnemonic you can ensure that the clipboard is available and remains open while you complete your desired operation. |
|
Note: | (OpenClipboard) is currently supported only in Comet32 and only when using the "X00", system device for clipboard access as demonstrated below. |
| Example: |
Length 254 & Local RESULT$ ! Define a variable Length 10.0 & Local ClipErr Open (1) "X00" ! Open system driver TryClipboardOpen: Print (1) (OpenClipboard) ! Copy data from clipboard Input (1) Result$ ! to this variable ClipErr = IHexDec(Result$) If (ClipErr EQ 5) Goto TryClipboardOpen ! This error indicates that the clipboard is in use If (ClipErr NE 0) Goto ErrExit Do other clipboard operations Print (1) (CloseClipboard) ! We're done - close the clipboard Close (1) ! Close system driver Goto Exit ErrExit: Print "Error opening clipboard: ";ClipErr Exit: Stop |
