问题 Thank you for taking the time to read this and I will appreciate every single response no mater the quality of content. :) I'm trying to create a php script which searches a text file for specific text. A person types in the specific text within a HTML form and the php script should search for that specific text within the text file. The value of the input field of the HTML form is "username" and within the php document, the variable "$username" is the entered data, example shown below:

Drawing a line using a Mouse Motion Listener

阅读更多关于 Drawing a line using a Mouse Motion Listener

问题 I'm new at using actionListener and mouselistner . I want to track the Mouse movements and connect the dots as I go. So it will be one continuous line. I am using the MouseMotionListener every time I move the mouse across the screen and get a new set of points. I am not using mousePressed or mouseReleased . Everytime I move the mouse, I can get every point of where my mouse's position is on my JPanel to show up on my results window, but in order to draw the line between two points, I'm not

问题 I have a text file named 1.txt which contains the following: 123456 011111 02222 03333 and I have created a python code which copy the first line to x number of folders to file number.txt then copy the second to x number of folders: progs = int(raw_input( "Folders Number : ")) with open('1.txt', 'r') as f: progs2 = f.read().splitlines() progs3 = int(raw_input( "Copy time for each line : ")) for i in xrange(progs): splis = int(math.ceil(float(progs)/len(progs3))) with open("{0}/number.txt"

How to make dashed grid lines intersect making crosshairs in gnuplot?

阅读更多关于 How to make dashed grid lines intersect making crosshairs in gnuplot?

问题 I'm plotting some data and I want to use dashed grid lines. Any dashed grid line would suffice, but I prefer a "long dash, short dash, long dash" format. For example, given the following code set grid lc rgb "#000000" lt 1 dt (50, 25, 20, 25) plot x**2 I get this result But I would rather the grid lines intersection to happen always at the middle of two dashes, like this If I could make horizontal grid lines different to vertical grid lines and I could add some offset to each one, then I'd

How to set the line width to 0.5 pt in ggplot2?

阅读更多关于 How to set the line width to 0.5 pt in ggplot2?

问题 In ggplot2 , it is easy to use element_text with argument size=6 to set the font size to 6 pt (For text, size has a unit of pt). However, we cannot use element_line with argument size=0.5 to set the line width to 0.5 pt (For line, size has no unit). So how to solve this problem? In grid package, I meet with the similar question. The code is as following: library(grid) grid.rect(width=unit(5, "cm"), height=unit(5, "cm"), gp=gpar(lwd=unit(2, "cm"))) and the result is: Obviously, the line width

How do I add a line as a sprite in pygame?

阅读更多关于 How do I add a line as a sprite in pygame?

问题 I want to add a grid to my level that stays with the terrain and not the screen. The way I thought of doing it is to add all the lines that form the grid as sprites and move them with the terrain, but I can't figure out how to represent the line as an image. I tried to do this myself, but had no success. EDIT: Here's what I've tried class Grid(): def __init__(self): self.grid = pygame.Surface(size) self.grid.set_colorkey((0,0,0)) def draw(self): # DRAW TILE LINES -----------------------------

ZedGraph - How to make a horizontal line drag-able?

阅读更多关于 ZedGraph - How to make a horizontal line drag-able?

问题 I have some straight horizontal lines that I want the user be able to drag vertically. How would this be possible? I think the best parameter for line selection would be a fixed number of pixels near the line. So if mouse is +/- 2 pixels, I should change the mouse cursor and make the line drag-able.. I see the CurveItem class has properties IsSelectable and IsSelected. Will these have any function in solving this issue? I can’t really understand what they are for from reading the class

Replace a specific line in a file using Ruby

阅读更多关于 Replace a specific line in a file using Ruby

问题 I have a text file (a.txt) that looks like the following. open close open open close open I need to find a way to replace the 3rd line with "close". I did some search and most method involve searching for the line than replace it. Can't really do it here since I don't want to turn all the "open" to "close". Essentially (for this case) I'm looking for a write version of IO.readlines("./a.txt") [2]. 回答1: How about something like: lines = File.readlines('file') lines[2] = 'close' << $/ File.open

firefoxs renders thin grey lines at content box edges of a png at certain widths - why?

阅读更多关于 firefoxs renders thin grey lines at content box edges of a png at certain widths - why?

问题 When firefox (3.0.6) renders a png image at certain widths (e.g., 50%), a thin grey line is shown along the left and top edges of the content box. The line disappears at other widths (e.g., 70%). Furthermore, the line doesn't seem to be present in the original image (using gimp to inspect the image). The phenomenon occurs in the absence of the CSS style markup -- in the HTML example below, the CSS is present to clarify where the grey lines are located -- it seems clear that the grey lines are
