vb.net - Remove first 27 characters from each line in richtextbox -

-

how go removing first 27 characters each line in richtextbox?

i have tried

for each in richtextbox1.lines         = richtextbox1.text.remove(0, 27)     next

if want preserve formatting in richtextbox, way:

private sub button1_click(sender object, e eventargs) handles button1.click     integer = 0 richtextbox1.lines.length - 1         dim index integer = richtextbox1.getfirstcharindexfromline(i)         richtextbox1.select(index, math.min(27, richtextbox1.lines(i).length))         richtextbox1.selectedtext = ""     next end sub

i have data grid rows represent theta (0, pi) , columns represent phi (0, 2*pi) , f(theta,phi) density of dark matter @ location. wanted calculate power spectrum , have decided use healpy. what can not understand how format data healpy use. if provide code (in python obvious reasons) or point me tutorial, great! have tried hand @ doing following code: #grid dimensions nrows*ncols (subject change) theta = np.linspace(0, np.pi, num=grid.shape[0])[:, none] phi = np.linspace(0, 2*np.pi, num=grid.shape[1]) nside = 512 print "pixel area: %.2f square degrees" % hp.nside2pixarea(nside, degrees=true) pix = hp.ang2pix(nside, theta, phi) healpix_map = np.zeros(hp.nside2npix(nside), dtype=np.double) healpix_map[pix] = grid but, when try execute code power spectrum. specifically, : cl = hp.anafast(healpix_map[pix], lmax=1024) i error: typeerror: bad number of pixels if point me tutorial or edit code great. more specifications: data in 2d np array , can change numrows/...
