It seems like with SAL equipped, legacy Win32 program can still be useable in future business world scenarios. Through building this legacy projects written in 1998 with VC++ 5.0, I still learned something new, especially SAL stuff from Microsoft. Run this application and we will see a message box pop up: MessageBox(NULL, TEXT( ' Hello, Windows 98!'), TEXT( ' HelloMsg'), 0) Īfter these fixes, we can see it compiles smoothly. */ #include int WINAPI WinMain(_In_ HINSTANCE hInstance, _In_opt_ HINSTANCE hPrevInstance, HelloMsg.c - Displays 'Hello, Windows 98!' in a message box Step 2Īdd a C language source code file such as main.c and copy the following code from Charles Petzold's book into this main.c. Step 1Ĭreate an empty project by this sequence in Visual Studio 2019: file->create new project->C++->Console application -> empty project. Let's see if we can make it work in Visual Studio 2019. I am using the first example in the book and will walk through the process.

Win32 Program of Hello World from the Book Let's dig some old legacy Win32 programs written in 1998 and see if they still work now. BackgroundĪlthough Windows has evolved over many versions, Win32 programming still holds its ground. I will continuously add more contents into this post and hope to resolve more compilation issues and warnings.

If you read through this post, it may save you a few hours trying to figure out how to do it. Here I aggregate them as an article to share here. So will these examples work in Visual Studio 2019? If not, how can we make them work? Here are some tips I gleaned through the internet and tested. These examples were compiled in Visual C++ 5.0 projects. It comes with a CD-Rom loaded with source code. Last weekend, I got an old book on Programming Windows by Charles Petzold published in 1998.
