I added another new tool to my Tiny Tools Collection: ToggleDisplay

Code: https://github.com/sgrottel/tiny-tools-collection/tree/main/ToggleDisplay
Released Binary: https://github.com/sgrottel/tiny-tools-collection/releases/tag/ToggleDisplay-v1.0

It allows you to enable, disable, and toggle a display.

Why? My computer is connected to 2-3 displays. Two computer monitors on my desk for work. And a TV on the other side of the room, e.g. to play games from my computer or to watch video files in style.

Often enough I boot the computer, and then my mouse disappears from the desktop, because I forgot the TV was configured “on” before, and the mouse moved beyond the desktop monitors. Annoying. The built-in feature “Windows-Key + P” is understandably limited to two monitors. So, I always had to press “Windows + P”, then “Further Settings”, wait for the dialog to appear, fiddle around, press apply, … you get my point.

So, I researched the net a bit on how to programmatically enable or disable a display. And there are several free tools to do that. I tried two, and both did not work. Then there is a hack with using a Windows 10 executable on Windows 11. Yeah, no. Ok. Search on!

It turns out, there is an easy API for that: ChangeDisplaySettingsEx. Some experimental code later I was able to deactivate the display, but not to (re-)activate it. Not good enough. Search on!

Some search later, turns out there is a second API, not as simple and with next to no useful documentation: SetDisplayConfig. This one seems to be the API the windows built in display configuration dialog uses. But … how. I found code by “PuFF1k” on StackOverflow (https://stackoverflow.com/a/62038912/552373) who reverse engineered the API calls of the windows dialog. I tried his code, and it works. Nice! Thank you, PuFF1k!

The core of the trick is to not provide any modeInfo data to SetDisplayConfig, and to set all sourceInfo.modeInfoIdx and targetInfo.modeInfoIdx of all paths to DISPLAYCONFIG_PATH_MODE_IDX_INVALID.

Some refactoring and some cleanup later, I have ToggleDisplay, ready to be shared with the world.

By the way, I now also included source code of some of my older tools in this Tiny Tools Collection repository:

I uses that opportunity to also update these projects to recent DotNet runtimes. I did not set up any automated build pipeline or releases. Maybe some other time.

Redate is another tool in my growing toolbox. The idea is simple: many applications generate files, write files, update files, with exactly the same content as before. The file write date, of course, is updated. The content stays the same. Other tools, then again, us the file write date as indicate if the files have been changed. Which makes sense, right.

So, this little tool, “Redate,” stores the MD5 hashes of the files, and their original write dates. When the tool is then re-run on that list of files, it restores the original write dates for all files with unchanged MD5s. And, that’s it.

I use it for Vue.js projects, to keep the write dates of files in the dist folders. Then, a simple FTP-sync only needs to update changed files for the final deployment. This helps for projects with many unchanged assets.

You can grab source and binary releases from github.

Simple computer graphics demos are often developed as console applications. Having the console window is simply convenient for debug output. However, if we then show these demos on our stereo powerwall, the console window flashing on program start is massively disturbing. That is why I take some time and wrote a little tool. It starts the console application, hides the console window, but captures the output. This way, we can still check what happened if something does not work.

I present the HiddenConsole:

And, because I can, the source is freely available:

NuGet is a handy package system for Visual Studio. Originally meant for Dotnet libraries it was extended some time to support native C++ projects as well. The only catch is, that the packages need to be made especially for NuGet. There are some, but by far not all which one (I) needs for the daily work. Most problematic is that many packages do not support Visual Studio 2013. And that is even today, as Visual Studio 2015 is almost here.

So there is only one thing to do: join the fray! Well, I could stay out of it and continue to grumble about it, but let’s just keep that as plan b. So, here it is; my first NuGet package:

the AntTweakBar v1.16

(with kind support of the author)

And this will not be the last you’ve seen of me.

Today I am presenting another small tool of mine: the ShutdownPlannerGUI

ShutdownPlannerGUI.zipShutdownPlannerGUI.zip Simple GUI for planned Shutdowns of MS Windows
[188 KB; MD5: 45cb64eef13ea47e98a7dcde0773e6f1; More Info]

The basic idea is simple: it is a small GUI, slapped together in C#, around the Shutdown command-line utility. It is about the timer, specifying when the system is going to shut down. The GUI provides several text boxes to conveniently enter the time in hours, minutes and seconds. And that is it.
