passing parameter to an executable program

[peiyoon]

Hi sir,

currently i m doing a research, i tried to launch a dos cmd windown using my program in vb.net and passing few parameters by parameters at one at time. how can i do so???

i am searching for advice and suggestions. i have tried the following ways in developing but i failed to get my result.

following are some of the ways tat i have tired, but i failed.
i have tried using the batch file to execute my pgp.exe program but it doesn;t work.

eg. a.bat (tis is my content of my batch file)
cd d:\
d:\pgpk -g (add a new user gp in my pgp.exe)
1 (expecting parameter)
1
(userid)
(phrase userid)
(confirm phrase userid)


the above is how i wrote my batch file. wen i execute it by this a.bat, the whole program will hang and i got to end the command prompt the my pgp.exe hang there. This is because the pgp.exe file expecting user interaction wf the program.

please advice me.
