由 孤街浪徒 提交于 2019-12-11 19:23:32

The main form displays the second form upon a button press, and the second form contains a DataGridView that is linked to an Access table on my local PC using a BindingSource (or DataSet, or what have you). When I first set the Data Source property of my grid to the table as a new data source

由 假如想象 提交于 2019-12-11 17:50:53
问题 I have an image in my app (android) taken from an URL: <img src="URL"/> If i change the image on the server (keeping the same URL), the app does not refresh and keeps always the old image.

由 和自甴很熟 提交于 2019-12-11 16:17:15
问题 When a user clicks the save button, I want all users currently in the page to be notified, or even better (or worse in a second thought) to enforce the page to refresh.
