Disables the “Merge Documents” window in the Printer Driver. If BLF_EXISTING_APPEND is set using the SetExistingFileAction function, but the Merge Window is disabled, the printer driver will merge documents silently in the background. To disable merging documents, the SetExistingFileAction function should be called with the BLF_EXISTING_RENAME or BLF_EXISTING_OVERWRITE parameters.

Input value - handle to the BlackIceDEVMODE.
Return value - TRUE if the merge window was successfully disabled, otherwise FALSE.
NOTE: For 32-bit applications , use pBlackIceDEVMODE as Integer, instead of Long.
