This blog post introduces a PowerShell script designed to automate this process efficiently. The script scans a specified directory, identifies file names containing prices using a regex pattern, extracts these values, and calculates their total, making it an ideal solution for tasks like invoice management.Windows Development3CC911B8-F4E2-494D-BCFD-AE2DD664BFC82025-01-02T08:08:35Z2025-01-02T08:08:35Zhttps://edi.wang/post/2020/2/4/how-to-check-if-net-core-program-is-running-under-remote-desktopThere are a few reasons that we need to know if our program is running under the Windows Remote Desktop (RDP) session. For example, if it is running under RDP, we may disable animation and other fancy graphics effects. But how can we detect if our program is currently under RDP? Let's see.
