Is it possible to combine Basic with Visual Basic.   I have a friend that has an exisitng basic program and he would like to chnage the menu system to Visual Basic, but still use the underlying basic program to do the work.  If it is possible how do I do it?

In your vb program

y$ = "c:\hello.bas"    'program path in QBASIC
x$ = "QBASIC /RUN " + y$

shell x$


This will auto run a Qbasic program  - if your using another Basic version similar command strings can be used

Another point!

You will want the focus in your DOS box so in the shell command use

shell x$ ,vbMaximizedFocus

It seems to work on my PC

Depending on the version of BASIC the old original code is in it may well port directly into VB with little or no changes. I have an extensive library of old DOS QuickBasic-IV code that I was able to dump into VB as Modules with few changes. The major area of difference that I found was that QB-IV allowed period as a placeholder in a variable name where VB5 Pro uses it as a separator between an object and it's property. A little fiddling with global search and replace selectively changing the .'s into _'s cleared that right up. The only other differences I noticed was the lack of a DATA/READ structure in VB. Once those were addressed it was only a matter of moments from that to a clean compile. Set the VB project properties to start the .BAS module and surround the code with:

SUB MAIN()

Old basic here
'
END SUB

and you should have a compilable VB5 module running the old code verbatim.
