How to refresh the form icon?

Question

When I edit the form icon, how to reflect the new changes on the old forms?

HI BenTam, im not sure if you are referring to Windows forms but in case you do, here is how you do it:

The process is very similar for WPF, notes at the bottom

Set the Icon in the Designer:

• Open your form in the design view.
• Select the form (click on the form itself).
• In the Properties window, find the Icon property.
• Set the Icon property to your new icon file.

Refresh/Rebuild the Project:

• Save all the changes.
• Click on Build from the top menu and choose Rebuild Solution. This ensures that all the changes are compiled into the executable.

Run the Application:

• Once rebuilt, run your application. You should see the new icon reflected on your form.

Update the Application Icon:

  - If you also want to change the icon of the executable (the one you see before the application starts), go to **`Project`** > **`YourProjectName Properties...`** > **`Application`** tab > and set the **`Icon`** there.

  **Clear Cache**:

     - Sometimes, Windows caches icons. If you've updated the icon, but the old one still appears when the program is running, it might be due to Windows caching the old icon. Restarting your computer can help, or you can refresh the icon cache manually.

     If you're using WPF, the process is similar but the properties and steps can be slightly different. In WPF, you would change the **`Icon`** property of the **`Window`** in the XAML or in the code-behind.

     If this helps, please mark it as the answer and consider following
