QBasic crashes immediately after selecting the "open" menu item

Question

Not sure if this is even an acceptable question, but I figured it's an IDE so...

I'm trying to write a small program in qb4.5, which has happily worked on my computer (XP SP3) for a while now. For some reason though it is now sluggish and error-prone. As the title reads, if I try to open a file then QB crashes out. A virus recently attacked my registry (among other things), and after removing it and fixing many entries there are probably some entries that I haven't corrected that may affect this.

Answer 1

I believe that QuickBasic uses the MSDOS edit command for its IDE

The QuickBASIC IDE (-> QB.EXE) is a self-contained application. QuickBASIC doesn't use the MS DOS editor (EDIT.COM) as an input screen. The QB IDE offers several features you won't find in EDIT.COM, for example a SUB/FUNCTION browser, live syntax checking, compile+launch menu, ...

The styling of the QB IDE looks very similar to the appearance of EDIT.COM but it's a different application. In fact, one can run QB.EXE in DOSBOX without even having EDIT.COM installed.

Answer 2

I believe that QuickBasic uses the MSDOS edit command for its IDE. Presumable that program is affected by the virus. If that is the case, you should have problems opening other files in EDIT too.
