Jan 2, 2011I made an email account today and out of curiosity I was wondering if this is possible. Is it? Has it ever been done before? How is it even possible? I mean, all that spam email I get, it must be generated emails doing that because even though I "mark as spam" it, I still get the same email but from another address.

Way To Capture Screen Image And Then Read Data (OCR?) From Image
Feb 13, 2010I play a game and in the game you acquire skills which you can display on the screen in a box very similar to a data grid. The grid has 3 columns and X number of rows.Column 1 is the name of the skill, column 2 has a descriptive term like "Beginner" and column has the number of points you have acquired in that skill. So it would look something like this:[code]Remember that it is in a data grid so it has cells like an Excel spreed sheet.The program that I use is able to parse the skill name and the points and save that information outside the game to a n area in the program.My question is, is this possible to do something similar in VB? That is something like, Press a hot key, with will get a screen shot, parse the data and save to a data grid in my VB program.

VS 2008 - Read A 16bit Binary File (tif Image) And Pixel Values Of The Image Ranges From 1200 To 4500 - EndOfStreamException Unhandled Error
Mar 18, 2012I am trying to read a 16bit binary file (tif image) and pixel values of the image ranges from 1200 to 4500. I tried to use BinaryReader using ReadUInt16 but I get EndOfStreamException Unhandled error. ReadByte method works fine with an 8bit tif file. I do not know how to read a 16bit image file using binaryReader. Shouldn't I use ReadUInt16 since values of pixels range from 1200 to 4500?

It appears that only a section of the string is not in plain values.I added the pipe separators for clarity. I have determined those columns are: EMPID | DateTime | TechID | Results | ResultType = Test.[code]

Encode/Decode Chinese Characters?
Nov 10, 2011I have a call to Server.URLEncode(string) from an old asp file that stores user input into a table. In this case it was a string of Chinese charters.
The actual data is :
%E8%B0%B7%E6%AD%8C%E7%9A%84%E5%89%8D%E6%99%AF%E9%BA%A6%E5%85%8B%E6%96%AF%E9%9F%A6
I rewrote the code to vb.Net and after I get the data from the table, I call
HttpContext.Current.Server.UrlDecode(string) to decode the string, add it existing mark up for an email and send it on its way.
Note that with Visual Studio i can see the HTML markup as it appears in the email, and ALL of the Chinese data is EXACTLY as I would expect it.
When the emial is received i get "???????????" characters where there should be the Chinese characters.
What I do not understand:
What Server.URLEncode actually encodes the data to. It appears to be HEX.
What the array of "?" means in outlook or any other email system that opens it, I assume it means "Hey i cant convert this stuff, so here is a question mark for kicks, good luck."
