Since people are asking about VB4D, and no-one's saying much about it:- Well, I installed Visual Basic for DOS (standard edition) on my system the other night. It took up about 4.3 meg of space. The IDE is not too bad, without a huge deal of difference to QB4.5's IDE. There is a small delay when switching to the Form Editor program. I compiled the example programs such as a clock and calculator app as standalone exe files (you can have a runtime module as well) and found that the EXE's are quite large- about 160k for the clock. Luckily, these exe's seem to run ok on a standard PC XT, which is a requirement for a financial app I have written in QB 4.5. I'm a little worried about this, as my app is around 4000 lines and in QB4.5 produces a 121k exe, which easily fits on a 360k disk. Hate to think what VB4D will make of it.... Overall, looks ok, but I'll reserve my judgement as to whether it's worth the Oz$149 upgrade cost. Steven Malikoff. steven@syacus.acus.oz.au

I too have a question concerning VB-DOS. I would like to know, whether
it is possible to run a VB-DOS application in graphics mode, so that
I can have text, listboxes, buttons etc. as well as a picture control
where I can draw lines. -- I have heard thet it supports full screen
graphics only (switch from text to graphics and back), but I hope that
this is not true...

Well, since people are expressing opinions about VB/DOS, I'll throw in my $0.02 worth. Firstly, I bought the professional edition upgrade for $199 which contains the whole 9 yards. Overlay support, ISAM support, etc.. I am using a 286-16 w/ a math chip & 2.5 Megs of RAM. 40 meg IDE harddrive. I must admit I was pretty suprised when I installed the software onto my system and found it needed ~11 Meg!! (my harddrive needed some house cleaning anyways :). I am in the midst of coverting several modules of a large appplication into VB/DOS from QB4.5. Each module was about 4000 lines in QB4.5 & I have about 4 or 5 modules. So far I have found VB extremely easy to use with excellent on line help and _MUCH_ improved documentation over QB45. The folks at MS finally ditched the idea of putting a users guide and a ref. manual in the same package. This makes it much easier to find stuff regaurding syntax etc. without having to wade through the entire users manual. As using VB is my first experience in using any type of object oriented programming, the basic idea took a little getting used to but again, the VB environment makes it simple for the novice to setup efficient event procedures for forms. Much of the "innerworkings" routines of my QB45 programs (ie data handling, file procedures etc.) was directly copied into my new VB programs and are working with no problems. Creating and editing forms is once again quite simple as the form editor is also quite user friendly. Again, good online help is one keystroke away:). It's so nice to be able to create a good looking user interface in a few minutes instead of struggling using LOCATE & COLOR statements all over the place. I really appreciate the extra programs included with VB. These programs contain dialog boxes which virtually every program uses and which can be used in any other programs by either adding them to the .MAK file (like you could ibn QB45) or by bunching several together and using them as a library (like I did). Both methods work flawlessly and save writing code for such things like an open file dialog box, a save file dialog box, a desktop setup dialog box, etc... All in all, VB is exaclty what I was looking for. A good efficient object oriented language which I didn't have to completely scrap my QB code, but the user interface is 1000% better looking then it used to be. -- ****************************************************************************** Peter G.
