navigation

问题 What I want to achieve is similar to this question (I can't comment so far, that is why I created the new question). I want this menu on the right side in the landscape mode (my activity allows only landscape). I need it to be scaled for any device size. It should have 5 items. For now, I wanted to do this by NavigationView like this: <android.support.design.widget.NavigationView xmlns:android="http://schemas.android.com/apk/res/android" xmlns:app="http://schemas.android.com/apk/res-auto"

After I click the "save" button on SecondWindow, the SecondWindow shall be closed and the DataGrid of MainWindow shall be updated. How to

问题 In C# WinForms, what's the proper way to get the backward/forward history stacks for the System.Windows.Forms.WebBrowser? 回答1: Check out http://www.bsalsa.com/downloads.html.

问题 Visual Studio tracks cursor positions and lets you move forward and backward through these positions. For example, you can type Ctrl+- to navigate backwards and Ctrl+Shift- to navigate forwards. I see that XCode tracks the history of which files you've visited, but does it also allow me to go forward and backward through the cursor locations?
