[DllImport("setupapi.dll", CharSet = CharSet.Auto, SetLastError = true)]
public static extern bool SetupFindNextLine(ref INFCONTEXT ContextIn, out INFCONTEXT ContextOut);
VB Signature:
Declare Function SetupFindNextLine Lib "setupapi.dll" (TODO) As TODO
User-Defined Types:
None.
Alternative Managed API:

Notes:
Parameters
| ContextIn | Pointer to the INF file context retrieved by a call to the SetupFindFirstLine function. |
| ContextOut | Pointer to a variable in which this function returns the context of the found line. ContextOut can point to ContextIn if the caller wishes. |
Return Value
If this function finds the next line, the return value is a nonzero value. Otherwise, the return value is zero. To get extended error information, call GetLastError.
Tips & Tricks:
None.
Sample Code:
C#
string infFile = <INF file full path>;
uint ErrorLine = 0;
IntPtr infHandle = SetupOpenInfFile(infFile, null, INF_STYLE_OLDNT | INF_STYLE_WIN4, out ErrorLine);
int iCode = Marshal.GetLastWin32Error();
if (infHandle.ToInt64() != INVALID_HANDLE_VALUE)
{
Console.WriteLine("INF file was opened successfully.");
INFCONTEXT Context = new INFCONTEXT();
if (SetupFindFirstLine(infHandle, "Manufacturer", null, ref Context) == true)
{
Console.WriteLine("Manufacturers list:");
string manufacturerName = "";
