HI!

You're right. It works.
I am now looking into installing/removing a service and I have
encountered a problem with LPVOID.
I have this Win32 function:
/*
BOOL WINAPI ChangeServiceConfig2(
SC_HANDLE hService,
DWORD dwInfoLevel,
LPVOID lpInfo
);*/
public boolean ChangeServiceConfig2(Pointer hService, int dwInfoLevel,
Pointer lpInfo);
lpInfo is a pointer to a structure which type depends on the dwInfoLevel
parameter. In my case, I want to pass a SERVICE_DESCRIPTION struct,
defined like this:
/*
typedef struct _SERVICE_DESCRIPTION {
LPTSTR lpDescription;
} SERVICE_DESCRIPTION,
*LPSERVICE_DESCRIPTION;*/
public static class SERVICE_DESCRIPTION extends Structure {
public String lpDescription;
}
Now, I am trying to do the call:
desc = new WINSVC.SERVICE_DESCRIPTION();
desc.lpDescription = "Test";
success = advapi32.ChangeServiceConfig2(service,
WINSVC.SERVICE_CONFIG_DESCRIPTION, desc.getPointer());
This returns true, but does not set the description. Am I doing
something wrong?
Thanks!
Thomas
