Progressbar does not update using Interface

I use VB .Net and try to do som intensive actions on a database (in a
seperate module). I defined an Interface for updating a progressbar on the
main form. When I test it from a procedure within the Main Form Class, all
works Ok. But when I use the Interface functions, the controls (ProgressBar,
Textboxes) are not updated, although the ProgressBar.Val ue is changed.
Me.Refresh(), Me.Invalidate() or Me.Update() and Appliocation.Do Events()
does not help. Has anyone got a clue? Does Interfaces work well? Are the
intensive calculations the problem? Should it help to do the calculations in
a seperate thread?

Hi all My requirement is to "on button_click, backup a SQL database using SQLDMO.Backup object and update the progress in a ProgressBar. The problem is the progress bar does not update at all until the very end of the backup process, when the backup is almost going to be over, the progress bar updates itself once on a stretch, which is no use,it is not showing any progress. SQLDMO documentation says, the SQLDMO.Backup object fires

Hi, thanks for the previous advice on progressbars with showing the percentage. I would now like to create a less clunky version. I.e at the moment my progressbar shows 7 separate steps. Some steps can take seconds to process, but others could take upto 10 minutes (leaving the users thinking nothing is happening!). Is there a way to show the progressbar smoothly increasing until the final step has finished instead of clunking it's way...

Please consider: foreach (ListViewItem item in listViewFiles.Items) { // Display the ProgressBar control. pBar1.Visible = true; // Set Minimum to 1 to represent the first file being copied. pBar1.Minimum = 1; // Set Maximum to the total number of files to copy. pBar1.Maximum = 4; //filenames.Length;

Overview: Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
