Desktop Auto-Load

Return to DisplayFusion Scripted Functions (Macros)

Description	This function applies a desktop icon profile, restores a backup of desktop gadget settings and applies them, and restores size and positions of currently running windows (restored ones only). I assigned the Hotkey 'Ctrl + Win + R' and the trigger "Change Monitor Profile' to this function and use that to restore the desktop info any time the monitor profile changes. I have another function 'Desktop Auto-Save' which is called by a hotkey and saves all that.

Nevertheless an attempt to restart them was made, leading to the opening // of the System32 folder. // // V2.02: // Improvement: // Some windows seem not to be on the right place when this function is triggered by a change in monitor profiles. // Only when calling it a second time it works. // Introduced a wait time. RearrangeWait variable contains this time. // 1s works most of the time, but not always // 2s seems also not OK. Moved to desktop windows only, wait 2s after desktop gadgets // 2s not enough, tried 5s // // V2.03: // Removed wait time because it doesn't work // Remove check, if Desktop Gadgets are running. Instead check, if a settings file for the profile exists // Check program windos before Desktop Gadgets // // V2.04: // Desktop gadget settings (sidebar): do not check, if setting exist. Info about start/stop is now stored with Program Settings // The path to the sidebar appliaciton will also be stored // Assure that LoadProgramSettings returns an object != null // // V2.05: Changes only in Desktop Auto-Save public static class DisplayFusionFunction { public static void Run(IntPtr windowHandle) { string app = ""; // Are there desktop gadgets running?
