• Allow for animations
  • Maybe add an option for timers?
  • How would we present this in a config file?
  • Maybe multiple timers at different intervals for different concurrent animation speeds?
• Add stretch option for each resource usable in ImageRenderer
• Improve Luna's screenshots Add XP visual style renderer
• Implement Quick Launch rendering
• Add layout options (constraints, padding, margin etc.)
• Preview theme in the config menu

In SCTT Alpha 0.0.7642.30810, time was displayed in 12 hour format (i.e., 3:00 PM). In the latest Beta 0.0.7709.39241, it's now in 24 hour format (i.e., 15:00).

Personally I prefer 12 hour, but I'm sure others prefer 24... is it possible to make a 12/24 hour option available in the Configuration window?

Fully DPI-awareness (PerMonitorV2)
Layout at 96dpi, scaled up afterwards
After scaling layout changes must be done at full DPI
Renderers will draw at full DPI
Branch: scaling (based on ad8110e)

General:

• Set high DPI mode to PerMonitorV2 (commit c2b17d6)

Taskbar:

• Disable WinForms automatic scaling (commit 2d1ada4)
• Manually scale the taskbar
• Reshow taskbars when scaling options changed
• Make renderers DPI aware when they change widths and positions

Settings:
To be done

If I open multiple windows or programs, as soon as more than 6 task bar buttons appear on the task bar, I get this message:

I can click OK to close it.

None of the open programs close, none of the task bar buttons disappear or stop working, and SCTT continues to function.

But, the message above will pop up again within 3 - 10 seconds, and continue to do so, until I close enough programs or windows to get it to stop.

When the message is up, I cannot use the task bar. For example, if I click a task bar button to bring an open window to the foreground, it instead brings the above message to the foreground. Until I click OK on the message, the task bar is locked.

So obviously this makes it very difficult to work when there are more than 6 task bar buttons.

No Windows event log is generated.

A SCTT log event is generated every time the message appears. Here's the contents of one:

Right click taskbar, select "Configure SCT Taskbar", get this window (don't know how to get this in English; I made a separate issue):

Click OK without touching anything, and SCTT crashes:

There is no taskbar at all after the crash (no system taskbar, no SCTT taskbar). I can get to the Start Menu by hitting the "Windows" key on the keyboard.

Not sure if there's any kind of log file saved anywhere. But there are two Windows Application Event logs; not sure if they tell you anything useful:

OS is Win 10 Pro x64 build 2004.

Currently running SCT 1.1.9 and SCTT Alpha 0.0.7642.30810, working as expected.

The current directory structure for SCT and SCTT, is SCT is in C:\SCT, and SCTT is in C:\SCT\Taskbar. There is also a zip archive of SCTT which contains the files in C:\SCT\Taskbar in C:\SCT\sctt.zip.

I tried installing the new SCTT Beta 0.0.7707.37574 the same way. I moved the above C:\SCT\Taskbar folder and C:\SCT\sctt.zip file to a backup directory, then downloaded SimpleClassicThemeTaskbar_x64.zip to C:\SCT and renamed it to sctt.zip. I then extracted this to C:\SCT\Taskbar. So my setup looks like this:

I first tried running SCT.exe (still at version 1.1.9). I found that the "Enable" and "Disable" buttons are now greyed out:

If I move and replace C:\SCT\sctt.zip and C:\SCT\Taskbar* with the older Alpha version 0.0.7642.30810, the above "Enable" and "Disable" buttons work again.

With the new SCTT Beta 0.0.7707.37574 folders back in place, I tried running SimpleClassicThemeTaskbar.exe directly. I received this error:

This dialog box disappears and does nothing regardless of which button, "Yes" or "No" is clicked.

I have Microsoft .NET installed up to 4.8. ASoft .NET Version Detector shows that I have installed Microsoft.NETCore.App 5.0.0.

Is there a specific installer I need for Microsoft .NET that I need in order to run SCTT Beta 0.0.7707.37574? If so, do you have a link to it?

Should I wait for a new version of SCT before I try running the new SCTT beta, since it appears that it breaks the current version 1.1.9? I see that SCT version 1.2.0 and 1.2.1 were posted but removed due to compatibility issues.

• Listen for messages of windows getting created/destroyed
• Reduce CPU usage of 'WindowIsOnCurrentDesktop(hWnd)' This function is now rarely called and has actually been optimized as far as it can.
• Look into repeating changing workspace area (glitching maximized windows)

Windows Vista/7 added following features:

• Progress inside taskbar
• Icon emblems
• Thumbnail actions

It would be awesome if there could be a classic backport of those features.

One issue, three bugs:
Shutting down causes SCTT to crash and your shutdown to automatically cancel
Right clicking and pressing Exit SCT Taskbar only closes the taskbar on the screen you close it on
Killing it sometimes breaks the registry config

Describe the bug
The tray does not appear on the taskbar

Reproduction
Everytime SCTT is open the tray does not appear

Expected behavior
I expected to see an arrow revealing the tray, like in the screenshots on the WinClassic Boards thread.

Screenshots

Environment:

• OS: (Win10 ver 1909)
• SCT Version (1.2.2)

I will do this in merge-master-tray (Based on tray)

• Fix text on task view items
• Make error messagebox close the loggers stream, open the file in notepad, and reopen the stream in append mode
• Replace all Windows 10 version checks with Windows 10 or higher version checks
• Make NetworkUI accessible through commandline but show warning about it being unfinished
• Make VDM Notification service just return 0 when it fails
• Implement old tray and make the new tray an option inside the settings menu (Maybe default it on W11)
• Replace the option to enable the new taskbar collection system with an option that restores the old one
• Fix bindingflags to actually save settings
• Customizable mouse actions
• Fix grouping
• Fix dragging around grouped windows
• Figure out why the config menu takes 3x as long to load as before
• Better hover highlight
  • Quick launch
  • System tray
• Finish Classic renderer for quick-launch
• Move stuff to SCT.Common
  • Error reporting
  • Logger
  • Config
• #41
• Fix bugs around new rewrite
• Clean code (if you know what I mean)
• Visual style previews

Starting from 0.0.7710.36086 the systray and clock functions aren't being called. This results in the clock being stuck at 5:03PM and the systray being empty.

I did some manual digging as to why SCTT seems to crash querying a process. A great article from Giorgi Dalakishvili shows why, TLDR: .NET Runtime is calling Win32 in a wrong way, requiring us to call things manually.

Sketch of possible UI/options:

In SCTT Alpha 0.0.7642.30810, Taskbar-Context-Menu-Tweaker worked for creating a classic grey Taskbar context menu.

In SCTT Beta 0.0.7709.39241, it no longer works:

Troubleshooting:

• Ensure C:\Windows\System32\TaskbarContextMenuTweaker.dll is present

• Kill and restart all explorer.exe processes after enabling SCT

• Run rundll32 TaskbarContextMenuTweaker.dll,Inject

Didn't work... is it possible to get Taskbar-Context-Menu-Tweaker functionality restored? (Obviously not a huge problem but still something that would be nice if it could still work!) :)

CsWin32 will take away the burden of having to write all native methods manually.
There's a good reason not to use it, it seems like the repository owners/maintainers aren't acting to issues (even ones created by myself). (just took longer than expected)

Right click taskbar, "Configure SCT Taskbar".

I see:

Any way to get this in English?

Currently while testing there are way too many cases where SCTT fails, like disposed handles, etc., causing the application to crash. This issue should track many of the unexpected exceptions.

• System.OverflowException: Arithmetic operation resulted in an overflow.
  UnmanagedCodeMigration.cs:232
• System.ObjectDisposedException: Cannot access a disposed object. Object name: 'Icon'.
  GroupedTaskbarProgram.cs:34

After I run SCT and close its box, Explorer is loaded and my Documents folder gets displayed.

Mostly an annoyance since I then have to close Explorer (I use a different file manager and never use the Documents folder). But something it would be good to fix if you get a chance.

SCTT's memory usage keeps increasing very slowly, but GC doesn't clean some things.

Currently most SCTT components compare UI against data, this is possible to improve, I'd suggest this:

1. probably make event/interface/class for item changes
2. for static updates/fetches/pulls, you compare those two collections and call events accordingly

I imagine sharing one base class/interface for either event-based updates or pulling.

Examples of old code

Most of SCTT's current code is like this.

List<Item> newItems = new();
foreach (var item in SomeItemSource)
{
    newItems.Add(item);
    if (!items.Contains(item))
    {
        /* some init here */
        items.Add(item);
    }
}

foreach (var item in items)
{
    if (!newItems.Contains(item))
    {
        _ = items.Remove(item);
        item.Dispose();
    }
}

/* additional processing here */

Open tasks partially render under the system tray.

Windows 10 Pro 2004 x64 / SCT 1.2.2.0 / SCTT 0.0.7712.2869

Using Custom button:

The leftmost taskbar button is too close to the start button:

This seems to happen after changing "Space between taskbar programs", even after changing it to the default setting of 2. If I change it it looks like this after clicking OK:

But clicking then minimizing the first program on the taskbar (next to the Start button) will result in the former image, where it appears to overlap.

For comparison here is the Windows 7 classic taskbar using Classic Shell:

And here is Windows XP:

It's clear there should be more space between the Start button and the first taskbar button. But I'm not sure if SCTT should be doing this, or if I should be adding transparent pixels to the right of the custom Start button PNG image.

I tried the development build and it crashed immediately. (Clicking "enable" in SCT.)

Right or left clicking any of the built in Windows system tray icons for Volume, Safely Remove Hardware, and Networking returns this error:

 
There are no Windows Events logs, but there are logs created in the SCTT folder:

I have no idea if it crashed or closed. Every 24 hours or so, the taskbar vanishes. SCTT closes and does not leave any other system taskbar in its place. There is simply no taskbar. I can bring up the Start menu by hitting the "Windows" key on the keyboard, then running SCT from there and click the "Enable" button which re-starts SCTT.

This didn't happen with any of the SCTT releases labeled as "Alpha" (i.e., Alpha 0.0.7642.30809, etc.)

This is a hard one to do anything with if you can't reproduce it, because I can't find any kind of tracing. There's no Windows Event log generated when SCTT shuts down, which seems to indicate (but doesn't necessarily mean) that it didn't crash.

I'm only running Windows Defender. I tried putting in an exclusion in for C:\SCT:

This had no effect on the issue.

I can't find any kind of logging for SCTT. Is there any way to get SCTT to generate verbose logging?

When opening any UWP app a button shows up on the taskbar, but it doesn't have the associated app icon.

• Check if the app is a UWP app before adding the button
• Find out which UWP app it is
• Locate the app icon and add it

• Support for transparent bitmaps (default XP VS seems to work fine but other bitmaps seem to have issues)
  • Add start button icon bitmaps.

• System tray icons
• Start button
• Quick launch items
• Program buttons

1. Open SCT from the file you downloaded
2. "Install" (auto-launch)
3. Open SCT from your Start Menu.
4. Click File -> Options (or press Alt+F and then O)
5. Select SCT Taskbar (alpha) in Taskbar Type (This is still incorrectly branded as SCT Taskbar is in beta not alpha anymore)
6. It'll ask you if you want to install SCT Taskbar, press Yes
7. Click OK
8. Press Enable

The above instructions were followed precisely on a clean installation of LTSB 2016. I've tried it with "Classic Taskbar" ticked and unticked and the result is the same.

https://i.imgur.com/GVZV6Qg.png

I have tried the current nightly on your WinClassic post and it just instantly crashes. No pop-up, just disappears from Task Manager. What's going on?

Quick Launch only shows 5 of my programs that are pinned in the normal taskbar, is there anyway to make it show more?
