#16 : Applying Windows Registry Settings

Today we continue to expand on our application configuration logic. We'll read the Windows registry to apply system-wide setting values. Registry values are applied first. Then, settings are tailored, first from the environment, or user, level and then from program arguments are specific to the execution of the program.

Here we've added a general routine to read a setting value from the Registry.

Next, we've added the routine that reads all defined Registry settings and applies them to our application class instance.

We'll call the new GetRegistryVars method as part of our overall configuration routine.

To test, we first add a value in our application's registry space, which was created when we installed Ava as a service. If you don't want to install Ava as a service, you can use the Registry editor to manually create the registry path.

We've created a registry entry for the log prefix.

Now, when we run Ava, we see that the logging prefix is applied from the Registry and the logging path is applied from our Environment, as we saw previously.

We can confirm the path and prefix by locating the log file created.

Day 12 : 19 June 2022 : Adding Windows Service Logic

Image
My 100 Daze of Code https://github.com/davidjwalling/100-days-of-code #12 : Adding Windows Service Logic Today, we'll add some Win32 API logic in Ava to install, uninstall and run as a service on Windows. We'll add logic in Driver::Service that check if the program was started with the "service" argument as the first program argument. If so, the Service Control Manager will be invoked to start the program as a service. We'll also check for "install" and "uninstall" program arguments and handle these with logic that installs and uninstalls the program, respectively. In a later post, we'll do the equivalent on Linux and macOS and show how to enable Ava to run as a daemon configured in sysctl. Nowadays there are shortcut methods to install and run an executable as a service on Windows. But I prefer to illustrate the APIs that make this work. Some Code Refactoring Up to now we've been using a pointer-to-implementation (pimpl) method for exp...

Day 5 : 12 June 2022 : CMake on Windows

Image
 My 100 Daze of Code https://github.com/davidjwalling/100-days-of-code Day 5 : 12 June 2022 : CMake on Windows So far, we've seen using CMake on Linux and MacOS. Also, we've looked at native compilation on Windows using Visual Studio (VS). Today, we'll look at using CMake on Windows. I decided to devote an entire day (hour) to this because there are several ways to invoke CMake on Windows, using different "Generators". A generator will write the inputs to the native build tools. But Wait, There's More ... Before heading to CMake, I wanted to first point out that VS' native tools can build just fine without using CMake, of course. To build using "msbuild," open an x64 Native Tools Command Prompt for Visual Studio - this is provided when VS is installed. Invoke msbuild and pass the solution name and the desired platform and configuration. msbuild ava.sln /p:Platform=x64 /p:Configuration=Debug Repeat for Debug and Release configurations for Win32 an...

Day 11: 18 June 2022 : Handling Program Arguments

Image
My 100 Daze of Code https://github.com/davidjwalling/100-days-of-code #11 : Handling Program Arguments Up to now we've been carrying around Ava's program argument count (argc) and value array (argv) into a Configure method. Now it's time to start doing something with those values. We'll define four program settings that can be set by passing program arguments: the logging level, path, prefix and suffix, and show examples of using them. Logging Parameter Storage The singleton theLog is instantiated inside the Ava library (libava). Default values for several logging parameters are set by the Log::Init method, which is called both by the Log class constructor and the destructor, by way of the Reset method, so that runtime values are not left in deallocated storage on operating systems that do not automatically clear memory upon deallocation. Logging Parameter Symbols We use namespaces and enums to define symbolic names for the logging parameters so that we have a single lo...
