progress-bar

问题 I'm new to asking questions here so any advice about that will be appreciated...but to my problem: I'm trying to switch from one activity to another, where I'll show some data from the server.

问题 I want to show the user detailed progress information when performing potentially lengthy database operations. Specifically, when inserting/updating data that may be on the order of hundreds of KB or MB. Currently, I'm using in-memory DataTables and DataRows which are then synced with the database via TableAdapter.Update calls.

问题 7z.exe do not show any extraction progress in cmd. "C:\Program Files\7-Zip\7zG.exe" -y x -pPASSWORD "D:\Myfile.rar" Extracts the file with a GUI progress-bar. But I don't want a GUI progress bar.
