View Full Version : Get version from a rc file?

21st August 2006, 19:46
Does anyone know how to get the version from an rc file? Or is there a better way to keep track of version within QT?

When I used MFC I used 'GetModuleFileName' a win api I passed in an 'AfxGetInstanceHandle' which is an MFC call. I really don't want to keep MFC in my qt program.

Thanks for any help!

I'm not sure how you mean. Do you want to get the version of the resource or the version of you application.

If you saved the application's version as a string resource, you can use a const QString or a define just as well.

rc files are fairly specific to Windows. ergo, I don't think Qt supports them. Qt has its own resource system to embed resources inside the executable, but is used mostly for storing individual files/graphics, not for plain strings - unless you want to store your string inside a separate file. Otherwise, storing version in a macro #define or const string is fairly typical (and more flexible/portable)

I tend to use a define in .pro file:

# MMmmPP
# MM = major, mm = minor, PP = patch

QString version = QString("%1.%2.%3")
.arg((MYAPP_VERSION & 0xFF0000) >> 16, 2, 16, QChar('0'))
.arg((MYAPP_VERSION & 0x00FF00) >> 8, 2, 16, QChar('0'))
.arg((MYAPP_VERSION & 0x0000FF), 2, 16, QChar('0')); // "03.12.01"
