Convert webpage to image from ASP.NET
I would like to create a function in C# that takes a specific webpage and coverts it to a JPG image from within ASP.NET. I don't want to do this via a third party or thumbnail service as I need the full image. I assume I would need to somehow leverage the webbrowser control from within ASP.NET but I just can't see where to get started....
Improving method to read signed 8-bit integers from hexadecimal.
Scenario: I have a string of hexadecimal characters which encode 8-bit signed integers. Each two characters represent a byte which employ the leftmost (MSB) bit as the sign (rather than two's complement). I am converting these to signed ints within a loop and wondered if there's a better way to do it. There are too many conversions and ...

What is the rationale to not allow overloading of C++ conversions operator with non-member functions
C++0x has added explicit conversion operators, but they must always be defined as members of the Source class. The same applies to the assignment operator, it must be defined on the Target class. When the Source and Target classes of the needed conversion are independent of each other, neither the Source can define a conversion operator...
How to change handedness of coordinates?
How to convert from Euler's coordinates E1 = (x1, y1, z1, yaw1, pitch1, roll1) to E2 = (x2, y2, z2, yaw2, pitch2, roll2) where x, y, z are the coordinates of a point and yaw, pitch, roll the direction/orientation of a vector which origin is the point. yaw is around y, pitch around x, roll around z. They are performed in that ord...

Convert Unix Epoch Time to Seconds in SQL or .NET
First let me thank you all for your help. What I need is a function that takes in a EPOCH time stamp, like 1452.235687 and converts it to a readable timestamp like '01-01-1970 00:00:00'. More specifically I only need the time not the date. If at all possible I would prefer a .NET function instead of a SQL stored procedure. However an S...
casting odd smallint time to to datetime format.
Hello everyone, I'm working with a db (SQL server 2008), and have an interesting issue with times stored in the db. The DBA who originally set it up was crafty and stored scheduled times as smallints in 12-hour form-- 6:00AM would be represented as 600. I've figured out how to split them into hours and minutes like thus: select floor(t...
