I have a VB app that is used in a medical environment to capture images from a digital camera. We are wanting to switch to the Kodak DCS Pro/N. The software development kit for the Kodak camera provides a firewire driver and a .dll with functions for capturing images, etc. I have no idea how to use that C++ .dll in my vb app. Does it have to be "converted" for use in VB? Can it be called directly? Where do I go from here?
