multithreading - C# Background Worker UI Update -


To get a large amount of data from the database without stopping the main thread, I try to use a background worker I am here. It works well, except that when it comes to updating the UI, the update will freeze the screen. The related code is as follows: 

  Private Zero contains bw_RunWorker (Object Sender, RunWorkerCompletedEventArgs e) {lvwTest.BegginUpdate (); LvwTest.Items.Clear (); // UI foreach to population (test data in test data) {ListViewItem lvi = lvwTest.Items.Add (ti.Value1); Lvi.SubItems.Add (ti.Value2); } LvwTest.EndUpdate (); }

The update takes approximately 2 to 3 seconds, for which the screen is locked. I know that only the main thread can update the screen, but is it possible to load this data in memory somehow (any other example in the background thread or any other list) and then display it? What I want to do is to program the program to refresh the data while not taking time in the main thread.

"post-text" itemprop = "text">

I want to load data in memory and use virtual mode listview I recommend. In this way, you only create ListViewItem objects because they are necessary.

Eclipse CDT variable colors in editor -

I hope this is a good question to ask here. This programming is related, so I thought it would be better than the superuser, so I am using the CDT C ++ Eclipse plugin. I know how the editor changes colors for some things But is there a way to do that all the variables are different colors? For example in KDEValue, it sets the local variables and square variables in different colors and bold square squares. Can I copy it to CDT? Eclips provides some level of color customization for text editor syntax You can see it on the following: There are many elements, including the Window> Preferences> C / C ++> Editor> Syntax color code that can be changed, assembly, Comments, Preprocessor and Doxian Under the code, it is possible to change the color of some variable types, such as global variables, local variable announcements, local variable references, and parameter variables. But I do not think the code is capable of changing the color of each variable declared....
