K8055D USB Intercace

[raphaelf]

Hallo Zusammen,

OS:Windows xp Professional
Compiler: Visual Studio .Net

Ich habe mir ein K8055D USB Intercace geholht (http://www.conrad.de/script/usb_experiment_interface.sap)und habe probiert über die Funktion OpenDevice mich zu verbinden.
Ich habe aber nicht geschaft.
Im Projekt verzeichniss liegt das DLL k8055D.dll. Ich weiss nicht was ich noch vergessen habe. Ich wäre für eine Hilfe sehr dankbar

Hier meine Fehlermeldung:
mainwindow.obj : error LNK2019: Nicht aufgelöstes externes Symbol '__imp__OpenD
vice@4', verwiesen in Funktion '"public: virtual void __thiscall MainWindow::in
tDevice(void)" (?initDevice@MainWindow@@UAEXXZ)'
tutorial1.exe : fatal error LNK1120: 1 unaufgelöste externe Verweise
NMAKE : fatal error U1077: 'link': Rückgabe-Code '0x460'
Stop.
