Help with PInvoke of a struct

[Michael]

Hi all,

I believe I'm not PInvoking this struct correctly.
Here's the API definition.

typedef struct _SP_DRVINFO_DATA {
DWORD cbSize;
DWORD DriverType;
ULONG_PTR Reserved;
TCHAR Description[LINE_LEN];
TCHAR MfgName[LINE_LEN];
TCHAR ProviderName[LINE_LEN];
FILETIME DriverDate;
DWORDLONG DriverVersion;
} SP_DRVINFOR_DATA, *PSP_DRVINFO_DATA;

Here's my latest implementation attempt:

[StructLayout(LayoutKind.Sequential)]
public struct SP_DRVINFO_DATA
{
public System.UInt32 cbSize;
public System.UInt32 DriverType;
public System.UIntPtr Reserved;

[MarshalAs(UnmanagedType.ByValTStr, SizeConst = 256)]
public System.String Description;

[MarshalAs(UnmanagedType.ByValTStr, SizeConst = 256)]
public System.String MfgName;

[MarshalAs(UnmanagedType.ByValTStr, SizeConst = 256)]
public System.String ProviderName;

public System.Runtime.InteropServices.ComTypes.FILETIME DriverDate;
public System.UInt64 DriverVersion;
}


Thanks, all

Here's my latest implementation attempt:

Looks correct to me (assuming LINE_LEN = 256).

Thanks Mattias,

I believe LINE_LEN is 256 . It's been a chore tracking down this latest
PInvoke problem .

I think my main hang up is w/ the TCHAR arrays... I'll start a separate, new
thread for that in this ng.
