Question

我写了一个简单的驱动程序，只打印“Hello World”到调试。我使用Visual Studio 2012 RC和WDK 8来创建一个空的驱动程序项目并编写了以下代码：

#include <NTDDK.h>

extern "C" NTSTATUS DriverEntry(IN PDRIVER_OBJECT pDriverObject, IN PUNICODE_STRING pRegistryPath) 
{
    pRegistryPath = pRegistryPath; //unused
    DbgPrint("Hello World!");
    pDriverObject->DriverUnload = NULL;
    return STATUS_SUCCESS;
}

我把它编译成win7 x64。我已经读过，为了安装和运行这个驱动程序，我需要写一个.inf文件，但我似乎无法做到这一点。我从WDK 8中获取了一个示例.inf文件并将其更改为与我的.sys文件匹配，但它毁了我的虚拟框win7 x64 :-)。所以我在VS2012中创建了一个过滤器驱动程序项目，取了.inf文件并将其更改为匹配我的.sys文件，当我安装它时没有任何开心。我试图运行它用

创建的新服务

net start MyDriver

但是没有打印到调试中，也没有在计算机中看到MyDriver-＆gt; Manage-＆gt; Services。我正在使用DebugView查看打印到调试的内容（http://technet.microsoft.com/en-us/sysinternals/bb896647.aspx）。

当然，我想写一个acctualy做某事的驱动程序，但同时我只想知道如何运行它。

我从VS2012获取的.inf文件已更改为：

当我尝试使用wdreg.exe安装并运行我的驱动程序时，它说“在INF文件中找不到制造商部分”。（来自http://www.jungo.com/st/support/documentation/windriver/10.3.0/wdpci_manual.mhtml/dyn_windows.html）我读了很多关于.inf文件（来自一些微软书和很多谷歌），我仍然不知道如何修复我的.inf文件。

如果有更简单的方法来运行我的驱动程序，我很乐意听到它。一旦我知道如何运行它，就可以轻松地调试真实产品。

谢谢！

编辑：我还在测试模式下使用Driver Signature Enforcement Overrider烧录.sys文件（http://www.ngohq.com/home.php?page=dseo）。

原来Rohan是对的。我无法找到在win7中查看调试打印的方法（Rohan链接用于vista），所以我刚刚创建了一个文件。

#include <wdm.h>
#include <Ntstrsafe.h>

extern "C" NTSTATUS DriverEntry(IN PDRIVER_OBJECT pDriverObject, IN PUNICODE_STRING pRegistryPath) 
{
    UNICODE_STRING     uniName;
    OBJECT_ATTRIBUTES  objAttr;

    RtlInitUnicodeString(&uniName, L"\\SystemRoot\\example12345.txt");
    InitializeObjectAttributes(&objAttr, &uniName,
                               OBJ_CASE_INSENSITIVE | OBJ_KERNEL_HANDLE,
                               NULL, NULL);

    HANDLE   handle;
    NTSTATUS ntstatus;
    IO_STATUS_BLOCK    ioStatusBlock;

    // Do not try to perform any file operations at higher IRQL levels.
    // Instead, you may use a work item or a system worker thread to perform file operations.

    if(KeGetCurrentIrql() != PASSIVE_LEVEL){
        return STATUS_INVALID_DEVICE_STATE; 
    }

    ntstatus = ZwCreateFile(&handle,
                            GENERIC_WRITE,
                            &objAttr, &ioStatusBlock, NULL,
                            FILE_ATTRIBUTE_NORMAL,
                            0,
                            FILE_OVERWRITE_IF, 
                            FILE_SYNCHRONOUS_IO_NONALERT,
                            NULL, 0);


    CHAR     buffer[30];
    size_t  cb;

    if(NT_SUCCESS(ntstatus)) {
        ntstatus = RtlStringCbPrintfA(buffer, sizeof(buffer), "This is a test\r\n");
        if(NT_SUCCESS(ntstatus)) {
            ntstatus = RtlStringCbLengthA(buffer, sizeof(buffer), &cb);
            if(NT_SUCCESS(ntstatus)) {
                ntstatus = ZwWriteFile(handle, NULL, NULL, NULL, &ioStatusBlock, buffer, (ULONG)cb, NULL, NULL);
            }
        }
        ZwClose(handle);
    }


    pRegistryPath = pRegistryPath;
    pDriverObject = pDriverObject;

    return STATUS_SUCCESS;
}

我使用了同样的.inf我在我的问题中写道然后输入了cmd

net start MyDriver2

并且文件example12345.txt是在C：/ Windows中创建的。

Answer 2

当您加载/启动驱动程序时，它已加载并在内核中运行，因此很可能是您的驱动程序已加载。但是您可能没有看到的DbgPrint消息是因为在Vista之后，使用DbgPrint记录的调试消息会被过滤掉而不会显示在输出中。

您可以参考此信息以启用DbgPrint消息。 Getting DbgPrint Output To Appear In Vista and Later

另一种方法是将DbgPrintEx与适当的组件和级别一起使用。
