问题 One of the ways to get number of lines from a file is this method in PowerShell: PS C:\Users\Pranav\Desktop\PS_Test_Scripts> $a=Get-Content .\sub.ps1 PS C:\Users\Pranav\Desktop\PS_Test_Scripts> $a.count 34 PS C:\Users\Pranav\Desktop\PS_Test_Scripts> However, when I have a large 800 MB text file, how do I get the line number from it without reading the whole file? The above method will consume too much RAM resulting in crashing the script or taking too long to complete. 回答1: Use Get-Content

问题 I am developing an application that has a few custom overlays on a MapView - representing vessels. When selecting a vessel, I am showing its previous positions on the map, again with custom overlay items, and I would like to connect them with a line.

That does not help me at all, since I have many points from different vessels, and cannot hard-code

问题 I want to bring back a question that was asked before: java draw line as the mouse is moved "I would like to add a feature to my application which allows the user to draw a straight line by clicking the mouse at the start location and releasing it at the end location. The line should move as the mouse moves until it is finally released; similar to the way that a line can be drawn using the Microsoft Paint application. How can implement this so that the line is repainted as it moves without

问题 !1I have the Canny edge output of a ear... i have connected the farthest two boundaries with a line(green). Now I want to draw a normal from the midpoint of this line to the outer boundary(left side). The code i have written helps me to plot a normal but i want the red line to exactly meet the white boundary. Also I want the point of intersection at the point where it meets. I have also thought about another method for the same.By changing 50 to 60 pixels (in the code) the red line crosses

问题 private void btnDump_Click(object sender, EventArgs e) { using (StreamWriter sw = new StreamWriter("E:\\TestFile.txt")) { // Add some text to the file. sw.WriteLine(txtChange.Text); } } This dumps the text of txtChange to a text file. txtChange is a Rich text box and has line breaks (new lines) in it.
