You’ve Got a New Verisign Authenticode Certificate – Now What?

The good news first: You can get a Verisign Authenticode code signing certificate for $99. Just check out https://sysdev.microsoft.com/ for details. This price even applies to the renewal when the original certificate expires after a year. The bad news: Actually getting the certificate and using it is not so easy. Here are some tips.

DsGetDcName Timeout

Today I was looking for the source of frequent delays when setting permissions from my new application SetACL Studio. I sprinkled the code with timestamped debug statements like these…

How to Map Generic Rights to Standard and Specific Rights

There are two equivalent ways trustees can be assigned a specific set of permissions on Windows: via generic rights and via a combination of standard and specific rights. Generic rights are identical for all object types. There are only four of them: GENERIC_READ (0x80000000) GENERIC_WRITE (0x40000000) GENERIC_EXECUTE (0x20000000) GENERIC_ALL (0x10000000) As the name implies, generic […]

What is the SYNCHRONIZE File Access Right?

When dealing with Windows NTFS file system permissions, one quickly encounters the SYNCHRONIZE access right, the purpose of which may not be obvious. SYNCHRONIZE belongs to the standard access rights, just like DELETE, READ_CONTROL, WRITE_DAC and WRITE_OWNER. Here is the definition of SYNCHRONIZE from MSDN (2010): The SYNCHRONIZE access right is defined within the standard […]

How to Generate Directory Listing with Full Path from Batch

Sometimes you need a list of all the files and/or folders in a directory with their full path, without any additional information. “DIR /B” would be the right command, if it only printed out the full path (it does that only if combined with the recursion parameter /S). Here is a way to print a […]

Taking Ownership Fails With UNC Path, Works Locally!?! Why?

Here is an interesting tidbit related to Windows security: Create a test file share, e.g. C:\temp\test, and share it with full permissions for everyone (share, not NTFS permissions) as “test” Create the following directory hierarchy below the share: C:\temp\test\1\2\3\4 Assign ownership of the four folders 1, 2, 3 and 4 to any user (but do […]

EFS Encryption and CopyFile(Ex): Why DIY is Better

Generally I am not the type to recommend re-implementing functionality present in some API. But with the Windows function CopyFile(Ex) there may be no alternative, because of the less than sub-optimal way Windows copies EFS-encrypted files: If the source encryption key can be used on the target (i.e. if the target computer can access the […]

How to Enable Drag and Drop for an Elevated MFC Application on Windows

Finding good information on how to enable drag and drop for MFC applications is hard enough (why?). But just when you think you should have it working, you hit a very solid wall: UIPI (User Interface Privilege Isolation, a variant of UAC, User Account Control). Because of “security” reasons, UIPI disables drag and drop from […]

Deploying Visual C++ Runtime Files as Private Assemblies

If you create a C++ project in Visual Studio and configure it to “Use MFC in a Shared DLL” (the default) you need to make sure the C runtime (CRT) and the MFC libraries are installed in the correct versions on the end user’s computer. That can be difficult. There are three ways to install […]

Visual Studio: Adding DLL References Whose Version Changes Frequently

Let’s assume you have a C# project in Visual Studio. In that project, you reference an assembly (DLL) created by another of your projects. Because both projects are in active development, the version number of the referenced assembly changes frequently. There is one easy way to solve this: Add a reference to the project by […]

Visual Studio: Fixing Broken $(WindowsSdkDir) Variable

If you get weird errors in Visual Studio that basically state files like Windows.h cannot be found, the reason may be a missing or incorrect WindowsSdkDir variable. In my case, working with Visual Studio 2008 SP1 (32 bit) on Windows 7 x64 (64 bit) everything was fine until I installed the Windows 7 SDK. After […]

Found my first bug in Windows 7 APIs: PdhBrowseCounters requires Elevation

I just found out the following, which does not seem to be documented anywhere: The Windows API has a function for displaying a dialog that lets the user select a specific performance counter from all counters available on the local or a remote computer. The dialog is used by perfmon.exe, for example, and looks like […]

Radio Buttons in MFC (Visual Studio 2008 / C++)

This is a quick and dirty description of how to use radio buttons in MFC, written because I could not find this information in a single place on the web. In the dialog editor: Create a new group with the group box control and set a meaningful caption Add radio button controls inside the group […]
