I love doing crossword puzzles: I’m a huge fan of Merle Reagle (I have all his books www.sundaycrosswords.com) and I love the NY Times Sunday puzzles, both of which come in the Seattle Times. We also love listening to the NPR Sunday Puzzle by Puzzlemaster Will Shortz, from whom we first heard about Sudoku a few weeks ago.
Crossword puzzles require a fairly large amount of prior knowledge to solve. Sudoku requires almost no prior knowledge: just logic and deduction.
My family has been enjoying Sudoko puzzles. In fact, about a month ago, both the newspapers to which we subscribe started carrying daily Sudoku puzzles within a week of each other (USA Today, Seattle Times). If you haven’t tried one give it a whirl. A Sudoku puzzle consists of a 3x3 grid of 3x3 grids of squares, some of which are prefilled with digits. Sudoku rules are simple. Enter digits from 1-9 in blank spaces. Each row, column and 3x3 square must have 1 of each digit. Each Sudoku has a unique solution that can be reached logically without guessing.
Before I wrote a program to generate Sudoku puzzles, I needed to learn about them first. There are many web sites that provide Sudoku puzzles. I started by copying them to a word document (using Alt-PrtScrn to capture to the clipboard), resizing them to fit many on a page, then printing them out. That became rather tedious, so I automated the process.
Here is some code to capture Sudoku puzzles from a web site and add them to a Word document, 9 to a page. Why 9 to a page? Because Sudoku is all about 3x3<g>.
The code automates Internet Explorer and Word. Just change the URL to a web site that produces Sudoku puzzles and adjust the x,y,width,height coordinates. Be sure to heed any copyright notices.
I’ll post code that helps solve a Sudoku puzzle next.

I try to modify your ScrnScrape() function to capture a web page into one image (jpg,png,bmp,gif,…) done with its URL…without success.
That code is already functionnal in other softs(c++..).
Can you adapt it for this circonstance with conjonction in gdiplus ?
I see that uses a VB function DrawToBitmap who is not implemented in VFP (.
Thanks in advance.
this is my code :
*******
publi apIE
do locfile("system.app") &&gdiplusX
apIE=createObject("internetexplorer.application")
apIE.visible=.f.
apIE.navigate("http://msdn.technetweb3.orcsweb.com/calvin_hsia/default.aspx?p=17")
do while apIE.busy or apIE.readystate#4
enddo
local scrollwidth,scrollHeight
scrollHeight = apIE.Document.Body.offsetHeight
scrollWidth = apIE.Document.Body.offsetWidth
with _screen.system.drawing
bm=.bitmap.new(scrollWidth,scrollHeight)
apIE.DrawToBitmap(bm, .Rectangle.new(0, 0, bm.Width, bm.Height)) &&dont work in VFP9
bm.Save("c:ywebcapture.png",.Imaging.ImageFormat.Png)
endwith
