问题 When installing the latest JRE 7 on Windows, it no longer adds the command java to the system path. So just calling java --version in bat file fails in that case (despite that Java from java.com is installed). What's a reliable way to find the java command installation directory in a windows bat file? I've seen it in the following locations: C:\Program Files\Java\jre6\bin\java.exe C:\Program Files\Java\jre7\bin\java.exe C:\Program Files (x86)\Java\jre7\bin\java.exe Not tried JRE 8 yet. Note:

问题 I am new to batch script, and I am trying to parse a file that has key value (kind) of pairs delimited by new line. For example: the value of abc 1234 the value of def 5678 the value of ghi 9876 I would like to read this file using new line as delimited so that I can access the values.

问题 I have found that this works PART of the time by inheriting the Windows Forms mouse point and subtracting out the height and width of my window to set the left and top (since my window's size is fixed): MyWindowObjectThatInheritsWindow window = new MyWindowObjectThatInheritsWindow(); System.Windows.Point mouseLocation = GetMousePositionWindowsForms(); window.Left = mouseLocation.X - 300; window.Top = mouseLocation.Y - 240; window.Show(); Edit: Here is the code for getting the mouse position..
