Merci - cela fonctionne parfaitement (je pense). – Cheetah
+1 exemple de travail impressionnant! – BradleyDotNET
Est-ce que SetupDiGetDeviceProperty ne fonctionne pas avec .NET? Je reçois toujours l'erreur 87, mais en C++ faire la même chose, avec les mêmes paramètres fonctionne très bien. Je pensais peut-être un problème de déclaration DLLImport, comme une différence étrange que j'ai vu était les paramètres de commande ont été poussés sur la pile était différente dans C++ .NET. Mais j'ai eu exactement la même déclaration pour l'importation que ce code ici (et essayé plusieurs réglages). – Malaise
