Enables the “Merge Documents” window in the Printer Driver. To use the merge window, the driver has to be set to append documents by calling the SetExistingFileAction function with the BLF_EXISTING_APPEND parameter. If BLF_EXISTING_APPEND is set, but the Merge Window is disabled, the printer driver will merge documents silently in the background.
EnableMergeWindow(pBlackIceDEVMODE As Long) As Boolean
Input value - handle to the BlackIceDEVMODE.
Return value - TRUE if the merge window was successfully enabled, otherwise FALSE.
NOTE: For 32-bit applications , use pBlackIceDEVMODE as Integer, instead of Long.
