i have developed a program which will take parameters from the selection screen and will send to the LPT using the VB prog.
i have used the function WS_EXECUTE in my abap prog. the parameters are concatenated in bcode1 string.like this..
call function 'WS_EXECUTE' exporting commandline = bcode1 program = 'c:\bprint\BPRINT.exe' inform = '' exceptions frontend_error = 1 no_batch = 2 prog_not_found = 3 illegal_option = 4 others = 5.
my issue is ..... when i press execute button the values on the barcode is not printing what they are passed. means previous string values are printing instead of the current one.
i have used "free memory" after end-of selection event. Still problem is not solved.
is there any problem with WS_EXECUTE function.
can anybody suggest me the changes to be made.?
