 |
|
Hi everybody
I'm having problems with SetupVerifyInfFile() in C#, on pinvoke.net there are no examples so I'm here looking for some light
The function raises an exception PInvokeStackImbalance, after of a deep research on internet the exception it's raised because the Type of the variables
This is the C# code:
| Code: |
[StructLayout(LayoutKind.Sequential, CharSet = CharSet.Auto)]
public struct SP_ALTPLATFORM_INFO_V2
{
public uint cbSize;
public uint Platform;
public uint MajorVersion;
public uint MinorVersion;
public uint ProcessorArchitecture;
public uint Flags;
public uint FirstValidatedMajorVersion;
public uint FirstValidatedMinorVersion;
}
[StructLayout(LayoutKind.Sequential, CharSet = CharSet.Auto)]
public struct SP_INF_SIGNER_INFO
{
public Int32 cbSize;
public string CatalogFile;
public string DigitalSigner;
public string DigitalSignerVersion;
}
[DllImport("setupapi.dll", CharSet = CharSet.Auto, SetLastError = true)]
public static extern bool SetupVerifyInfFile([MarshalAs(UnmanagedType.LPTStr)] string InfName,
SP_ALTPLATFORM_INFO_V2 AltPlatformInfo,
out SP_INF_SIGNER_INFO InfFileName);
static void Main(string[] args)
{
SP_ALTPLATFORM_INFO_V2 pinfo = new SP_ALTPLATFORM_INFO_V2();
pinfo.cbSize =(uint)Marshal.SizeOf(pinfo);
//pinfo.Platform = VER_PLATFORM_WIN32_NT;
SP_INF_SIGNER_INFO pfname = new SP_INF_SIGNER_INFO();
pfname.cbSize = Marshal.SizeOf(pfname);
if (SetupVerifyInfFile(@"C:\WINDOWS\INF\OEM12.INF", pinfo, out pfname)) // <-- The exception PInvokeStackImbalance it's raised here!
{
}
}
|
The problem is in SP_ALTPLATFORM_INFO_V2 struct, if I comment all the inside variables it does not raise the exception so the SP_INF_SIGNER_INFO struct it's fine but obviously the function return FALSE
I have changed the variables types to uint, int, Int16, Int32, Int64... but without good results
Here is the C language code of the SP_ALTPLATFORM_INFO_V2 struct
http://msdn.microsoft.com/en-us/library/aa377636%28v=vs.85%29.aspx
| Code: |
typedef struct _SP_ALTPLATFORM_INFO_V2 {
DWORD cbSize;
DWORD Platform;
DWORD MajorVersion;
DWORD MinorVersion;
WORD ProcessorArchitecture;
WORD Flags;
DWORD FirstValidatedMajorVersion;
DWORD FirstValidatedMinorVersion;
} SP_ALTPLATFORM_INFO_V2, *PSP_ALTPLATFORM_INFO_V2;
|
And the SetupVerifyInfFile() in C language:
http://msdn.microsoft.com/en-us/library/aa377447%28v=vs.85%29.aspx
| Code: |
BOOL SetupVerifyInfFile(
__in PCWSTR InfName,
__in PSP_ALTPLATFORM_FORM AltPlatformInfo,
__out PSP_INF_SIGNER_INFO_W InfFileName
); |
Thanks in advance! |

The PInvoke forum is to ask for or comment on content of the PInvoke website, and does not offer any code help. Probably Stack Overflow is a better place to ask this sort of question.
In my experience, you have to be careful with structs and make sure the data length adds up. I've also used a lot of attributes that seem to help sometimes like
| Code: |
[StructLayout(LayoutKind.Sequential, Pack = 1)]
public struct UNICODE_STRING... |
And trying to force Marshal to use certain unmanaged datatypes like this:
| Code: |
void DefineDocument([MarshalAs(UnmanagedType.LPWStr)] String url,
...
[MarshalAs(UnmanagedType.Interface)] out ISymUnmanagedDocumentWriter RetVal); |
Good luck!
