What did i need if i compile my program into exe file.

i was compile my program to exe file call "maths.exe"
then if i install to a computer that do have visual basic,
what dll file i need to install in the "c:\window/system"
in order to run my program in non vb environment?

that depends on what you've included ... if u just used the controls that are set up for u then all u have to include is the msvbxxm.dll (where xx is the version of vb that you have so if u have vb5 then it would look like msvb50m.dll

what else i need ,vbrun300.dll need or not?

what version of vb do u have ?
what controls r u using ?

did u just use like textboxes, command buttons and that's it? if so like i said u only need the msvbxxm.dll file ...
