Is it possible to extract all the commit history involving SubProject-0 from the parent git repository and move it to a new one? 回答1: See http://git-scm.com/docs/git-filter-branch I

问题 Let's say that I have a data frame that looks like this...

问题 If I have a Vista .ico file which contains a 16x16, 32x32, 256x256 etc. version of an icon, I can successfully load it as a .NET Icon by simply doing -: Icon myIcon = new Icon("C:\\MyIcon.ico"); I can then access all of the various sized images in the icon. I can even access the 256x256 Vista PNG using methods detailed HERE. However, I haven't found a way to get the full set of icon images from a Vista executable. Unfortunately, doing this -: Icon myIcon = Icon.ExtractAssociatedIcon("C:\

问题 I have a Spatialline that I converted from a polygon shapefile (digitized manually based on features in "imagebrick" - this means that spatially the "polyline" and "imagebrick" are overlapped as I wanted) polyline <- as(shapefiles_data[1,],"SpatialLines") > polyline class : SpatialLines features : 1 extent : 357714.3, 357719, 4076030, 4076035 (xmin, xmax, ymin, ymax) coord. ref. : +proj=utm +zone=11 +datum=NAD27 +units=m +no_defs +ellps=clrk66 +nadgrids=@conus,@alaska,@ntv2_0.gsb,@ntv1_can

问题 First of all, I am not aiming for a specific development answer, but rather a development approach. The problem that I am having, is I have a client with a enormous amount of articles in PDFs, about 150 articles in fifty pdfs per year for the last 20 years. All of these PDFs are compiled from Quark express, from people with macs (if that info matters). Every time a new pdf magazine is created, the web-development team copy and pastes (!) each article into a form on the internet (!), incl.
