How to subtly inform the user that his input has been received

I am writing a DLL that automatically loads upon loading in a specific application. Since I would like to run the program while working on it, and my users may want to download the program without it in certain cases (for example, when searching for errors), I sometimes want to prevent the DLL from loading. I am currently doing this by checking GetKeyState for VK_LCONTROL, VK_LSHIFT and VK_LMENU at boot, and if everything does not work, I silently unload myself. However, loading the program may take a few seconds and see if the DLL was loaded or not, so I want to inform users about unloading. I reviewed MessageBox, but it is too destructive. I tried MessageBeep but didn't seem to do anything in my setup. I am currently using a simple double beep (Beep, Sleep, Beep) to indicate discharge,but it will probably become quite annoying for my staff. I also looked at the system tray icon, but that would have created a lot of code features and errors, while I'm going to get a minimal notification so as not to introduce any subtle errors.

Does anyone else know a subtle way (preferably visual) to tell the user that their input has been successfully accepted?

Given the limited scope of your goal, it may actually be the appropriate use of tooltips for taskbar tooltips .

If your application has a status bar at the bottom, you can place the message text there ...

:

  • Rotate it. Have a visual indication when loading the DLL and no indicator, tell you that the DLL has been unloaded. Perhaps the suffix in the title bar. That way you can tell at any time, not just during startup.

  • FlashWindowEx .
