I am trying to rotate a select number of bits to right with click of a button. ( bit 7 to bit 0 and rotate.) The patterns should not matter. It could be any combination of set or reset bits. The bit patterns are selected by checkbox0 to checkbox7. I like to rotate without a carry bit. Is there any way(s) to do this?

I'm using Visual Studio 2008 on an XP machine and am trying to develop a web app that can interact with websites and carry out automatic tasks.One problem I have is trying to recreate the web requests for automatic interaction.
For example:I use a webBrowser control to allow me to surf a page manually. Then, once I am at a specific location, I'd like the automatic interaction to take over.Part of the website requires a log-in and exchanges cookie data.When I try to read the cookie info from the webbrowser control to build the subsequent automatic requests, the cookie content is incomplete.Upon further investigation, it appears that the site sets one of the cookies to "http only". This stops the value being visible to the webbrowser control.Is there another control or method I could use to retrieve this info?
Which is the most efficient and speedy data structure in order to carry out calculations on it?. I have seen, collections, arrays, list arrays, databases and more. I would prefer to write just straight forward code that will be effective and which I can still understand. What I would like to do initially is have the ability to add new draws to the end of the file, edit the individual files and delete lines if required.
File would then be reformatted to show the corrections made. Some kind of data entry window is envisioned. As far as number crunching goes, I would like to make counts of each number in each of the columns , calculating averages, times since last drawn and so on.
Without being too long winded, I would eventually like to find triple combinations and maybe use them as predictions. So there you have it. This way I won�t have to go off on the wrong path, on a data structure that may not be able, or be too slow for the tasks at hand.
I have an asp:table which I want to exported to excel. One of my fields are alpha numeric and when exported to excel the leading 0s are stripped off. After going through this thread: Validation (CSS 2.0): 'mso-number-format' is not a known CSS property name I would like to use the css method "mso-number-format:@;.But the css is not exported to excel. I just tried to test it with simpler css things like bold font etc but its not getting carried over. I can see that if I surround my asp:Label with tags this change gets carried over to the excel but not the css bold . Other solutions in other thread does not work for me as ="00111" shows up as desired in excel but in the web form it shows up as ="00111" which is not what i want.
View 2 RepliesLet's say you have a user class. When the user is logged in there are properties representing basic user info, an associated address and, say, 5 profile pictures, the last a generic lsit like this: Private _photos As List(Of Photo). However, instead of carrying the weight of the profile pictures in a session vairable, to reduce resource usage, I only want to populate them if the user needs to acces them. So, for the most part, the generic list of photo's is empty. Will it carry weight anyway? I'm trying to decide if I should just not populate ituntil needed, or if I should create an alternative "light" user class which doesn't have this property.

Trying to develop a text editor, I've got two textboxes, and a button below each one.When the button below textbox1 is pressed, it is supposed to convert the Unicode text (intended to be Japanese) to Shift-JIS.The reason why I am doing this is because the software VOCALOID2 only allows ANSI and Shift-JIS encoding text to be pasted into the lyrics system. Users of the application normally have their keyboard set to change to Japanese already, but it types in Unicode.How can I convert Unicode text to Shift-JIS when SJIS isn't available in the System.Text.Encoding types?
View 1 RepliesIn vb6 when you wanted to alter the effect of a mouse click, you could use the mouse down event and alternate the action depending on the value of the shift, control and alternate key. (and also detecting if the right or left mouse button was clicked)

I'm trying to make a prank program that registers all of the letter keys on the keyboard and then will make random message boxes pop-up when you press certain ones, or just re-arrange the letters.But before adding any pranks, I'm trying to just get all of the hotkeys to work like a normal keyboard because when you register a key to be a hotkey, it no longer works for anything else. So registering "e" in the program will cause "e" to do nothing when your in notepad or something.
So far I've gotten pretty much everything to work except for this weird Shift bug. Whenever I press Shift and then a letter, the Sendkeys will correctly send the uppercase key, however as soon as I release shift and press a key without it, it still keeps the uppercase for one more letter.So if I press Shift + E then "E" will be successfully sent to Notepad, but then if I just press "b", "B" will be sent instead, but then after that first error it will successfully send lowercase again.
I was using wordlabel to store the letters so as to see if the shift uppercase problem was something in my coding, but actually when I press Shift + A and then just press a, it will do Aa in the label but AA in a program with the focus, like Notepad. So I don't know if this is a problem with Sendkeys or what but does anyone know of a solution?
I have this code which shifts the alphabet by a certain amount. The size of the alphabet is 26. When I enter a larger size shift (for example 22) I get some weird characters displaying. I think I need to mod the ASCII alphabet to 26 to get it working but Im not quite sure which bit to mod. Basically I need to wrap around the alphabet (once it reaches Z it goes back to letter A) Do I have to create a dictionary for the mod to work (like A = 0... Z = 26) or can I stick with using the normal ASCII table? Here is the code below:
Public Function encrypt(ByVal input As String) 'input is a variable within the funcion
Dim n as Integer

I have some questions regarding vb.net bit shifting. I understand the << >> operators are bit shift operators in vb.net. I have a two byte hex value 0x3ACC, each bit in this two byte represents either a day, month or year. The bit structure of this hex value is yyyy yyym mmmd dddd. I am confused as to how I should bit shift these values so that year, month and day are in their own UINT16 values. Just want to know about shifting numbers and if I need to add any padding to the shift?
