Microsoft Visual C++ 1.5 Professional

[Daniel Zaharia]

The difference must be between MV C++1.5 and MV C++ 1.5 Professional. I the first does not support development of DOS applications

Are you needing to modify an existing project, or create a new one? If the latter, could you use VC++ v6?

I need to compile a file. But it must be older that VC++ 1.5 (it must be on 16 bits)

Which i think takes you back to v1.0. Are you needing to modify an existing project, or create a new one? What is the target OS?

DR DOS (not MS DOS!) It is about an barecode scanner from Symbol. They have their own operating system. They provide some examples .C and .exe. I need to modify a bit the sample file and compile it to .exe. My .exe does not work.(even if i copile exactly the same file that generated their exe). Of course, customer support is off.

and their exe works ? The problem could be somewhere else not in the compiler

Where?

Write the software using assembler... then you don't have any problems :D Don't try it, just do it! ;-)

we use MVC 1.52 to compile DOS 6.22 applications all the time here at work...and have been for almost 10 years...as far as I know 1.52 is a complete package...I don't recall separate Standard/Pro versions. Steve

[Gordon Brandly]

I agree with Steve; I don't think there were separate Standard and Pro versions. I just checked our CD here at work -- it says nothing about being any particular edition. That said, as long as Symbol gives you standard C libraries and headers, you could always use Open Watcom[^], which I understand still compiles 16-bit DOS programs.

I'm very confused .. In the documentation they say: For writing applications for Series 3000 terminals: • The Microsoft Visual C++ 1.5 development system should be installed on your development PC. Note: It is important that you use the Microsoft Visual C++ Professional edition, and not just Microsoft Visual C++. The latter does not support the development of DOS applications. Further on in the documentation there are mix references to MV C++1.5 and MV C++ 1.52. I could not find any professional version of VC++1.52 . But the fact is that the executable that i compile with VC++1.52 is different from the one that they provide. It is slightly bigger and it isn’t fully functional (some parts doesn’t work). Any way , someone responded me from Symbol so maybe there is a chance. Thank you for you posts!
