Hallo,
ich versuche grade eine externe, vermutlich native dll, in ein Programm zur Farbtonmessung einzubinden. Die "eXact.dll" wurde vom Messgerätehersteller bereitgestellt. Leider kommt immer ein Fehler den ich nicht weg bekomme. Ich habe alternative mal ein bisschen mit der "kernel32.dll" probiert, diese funktioniert.
Hier erstmal mein Code.
Beim Aufruf von _connect kommt die Fehlermeldung
An attempt was made to load a program with an incorrct format.
Ich habe auch noch ein Beispielprogramm in C++ (2010) dabei, dies läuft aber leider bei mir nicht. Dies ist wohl die header Datei
Kennt sich damit jemand aus und kann mir helfen die dll richtig anzusprechen?
