Icons don't appear in projects (Windows)

@Platinum-Lucario said in Icons don't appear in projects (Windows):

@mrjj I know I have Visual Studio 2017 Community Edition installed, but surely this wouldn't prevent Qt Creator from loading the plugins, right?

well the Creator is compiled with vs and its runtime could affect it but
that should cause more global issues than just jpg and ico not working.

try to search your installation for qjpeg.dll and see if some app also installed a version.

And as for the imageformats plugin folder, it's there:

This is not the folder you want. This folder contains development plugins for the apps that you build.

Your issue is that Qt Creator can't read the icons. Qt Creator is a Qt-based application too, and it uses its own plugins (not your development plugins).

1. Check C:\Qt\Tools\QtCreator\bin\plugins\imageformats\ to make sure that qico.dll and qjpeg.dll are there
2. Try to open the resource editor again. When the window is open, use ListDLLs (https://docs.microsoft.com/en-us/sysinternals/downloads/listdlls ) to see which DLLs are loaded by Qt Creator. Do you see qico.dll and qjpeg.dll in the list? Are they loaded from the correct folder?

This is the files listed in the directory you mentioned, anything missing that requires it to work?

And of course, I ran ListDlls64.exe with the commands -r -v -d qjpeg.dll and this was the result:

And I ran ListDlls.exe with the same commands, and this was the result:

I ran them both as Administrator.

@Platinum-Lucario said in Icons don't appear in projects (Windows):

I ran ListDlls64.exe with the commands -r -v -d qjpeg.dll and this was the result:

I don't see Qt Creator in your screenshots.

1. Launch Qt Creator and open the resource editor.
2. Run ListDLLs64.exe QtCreator

I suspect that you'll see Qt Creator using plugins from a different folder instead of C:\Qt\Tools\QtCreator. Remove that other folder from your global PATH.

@JKSH These were the results when running the command, while having Qt Creator open (with the resource editor?):

And have I opened up the correct resource editor?

[jsulm]

@Platinum-Lucario You should copy paste the text from the terminal instead of posting screenshots only showing part of the output.

[JKSH]

@Platinum-Lucario said in Icons don't appear in projects (Windows):

These were the results when running the command

Your Qt Creator is loading DLLs from external folders:

• C:\Program Files (x86)\RedFox\AnyDVD\ADvdDiscHlp.dll
• C:\Users\Silve\AppData\Local\Microsoft\OneDrive\19.232.1124.0005\FileSyncShell.dll

Remove these 2 folders from your PATH, reboot, and see if that helps.

[Platinum Lucario]

@JKSH Do I remove the folders entirely from the locations provided? Or is there some file or directory that tells Qt Creator which .dll paths to load?

[hskoglund]

Hi, you don't need to remove the folders from your computer, what @JKSH meant was to remove them from the PATH environment variable. One quick test you can do, start a CMD window and type:

set path=
c:\qt\tools\qtcreator\bin\qtcreator

This will temporarily (only for that CMD window) remove all folders from your PATH. If Qt Creator starts up with the icons now visible (via then 2nd line above) then something in your PATH environment variable is the problem.

P.S. Also please uninstall your GeForce Experience, sometimes it doesn't play nicely with non-Steam apps (like Qt).

[JKSH]

@Platinum-Lucario said in Icons don't appear in projects (Windows):

It's not a file or directory; it is a "variable" in your operating system called the system PATH. The PATH tells all applications on your PC where to find DLLs.

See https://opentechguides.com/how-to/article/windows-10/113/windows-10-set-path.html to learn about (but do not touch the Registry unless you're not 100% sure what you're doing!)

Alrighty, I'll definitely give that a go as well! And possibly uninstall GeForce Experience

I've opened up PATH in the environment variable editor, and I've noticed that C:\Qt entries are not in there. Do I have to add in the C:\Qt entries in there?

Here are the entries in PATH:

And from what I can see, "C:\Program Files (x86)\RedFox\AnyDVD\ADvdDiscHlp.dll" and "C:\Users\Silve\AppData\Local\Microsoft\OneDrive\19.232.1124.0005\FileSyncShell.dll" aren't in there.

[JKSH]

@Platinum-Lucario said in Icons don't appear in projects (Windows):

Do I have to add in the C:\Qt entries in there?

No, don't add anything to the global PATH.

Having too many things in the PATH is common cause of problems. Qt does not need to be in the PATH.

Here are the entries in PATH:

You have posted the System PATH; you must also look at your User PATH (under "User variables for Silve")

And from what I can see, "C:\Program Files (x86)\RedFox\AnyDVD\ADvdDiscHlp.dll" and "C:\Users\Silve\AppData\Local\Microsoft\OneDrive\19.232.1124.0005\FileSyncShell.dll" aren't in there.

The PATH is a variable containing folders.

Check every folder in your PATHs and ensure that they don't contain Qt DLLs. Otherwise, you find yourself in DLL Hell

Anyway, I'm guessing that C:\Users\Silve\AppData\Local\Microsoft\OneDrive\19.232.1124.0005\ is causing you problems. OneDrive uses Qt. If Qt Creator tries to load the imageformats DLLs from OneDrive, it will fail.

[Platinum Lucario]

@JKSH Interesting, the only entry in the User PATH is:

%USERPROFILE%\AppData\Local\Microsoft\WindowsApps

Could this actually be the cause of the problem?

%USERPROFILE%\AppData\Local\Microsoft\WindowsApps

I'm not sure. %USERPROFILE%\AppData\Local\Microsoft\WindowsApps is meant to be there.

Well, for some reason your OS is linking DLLs from C:\Program Files (x86)\RedFox\AnyDVD\ and C:\Users\Silve\AppData\Local\Microsoft\OneDrive\19.232.1124.0005\ into Qt Creator, which is not supposed to happen. You'll need to find out what's causing this.

[Platinum Lucario]

@JKSH I'm not sure exactly what fixed it, but it's all working now! Either it was updating the NVIDIA GeForce driver, running Listdlls64.exe or enabling Windows Sandbox in the optional features that solved it, since it started working after rebooting my PC. I didn't even change anything in the Environment Variables.

Thank you for sharing your solution.
