i m trying to write a program that displays in a textbox a table of the binary, octal, and hexadecimal equivalents of the decimal numbers in range 1-222.
View 3 Repliesalright iam having an issue with this my code is working however i cant figure out 1 oftwo things 1. how do i get the numbers to align under their proper title like binary numbers under the word binary and 2. what can i add to ensure that no one can type in the txtbox or anything else to make sure the code cant be broken ?? HELP PLZZZZ =] here is my code:

I have a hw assignment and it asks this: program Description: Write a program that has four sub procedures that will calculate and print out a table of numbers 0 to 17 in decimal, hex, octal, and binary notation. Statements Required: output, loop control, subprogram
Sample Output: (you will design your own output but 4 adjacent label boxes would be suitable) [Code] What I want to know is how do I display my numbers from 1 to 17 as either Hex, Decimal, Octal or Binary. Also how would I display that on my form?
I was going to try to write a hex/octal/binary/decimal converter in Visual Basic 2010 express and was wondering how I would start to do this.
View 2 RepliesI'd like to convert a string which contains a decimal number into string that contains the binary value, the octal and the hexadecimal value of that decimal number.Afterwards I also like to convert a string containing a binary, octal and hexd. number into a decimal string.Basically I'm looking for the functions:
dec2bin
dec2oct
dec2hex
bin2dec
oct2dec
hex2dec
I'd not prefer to rewrite a function, I'm sure the framework must have these functions already.
I have this code for a decimal to binary conversion in a calculator. It is working, but when I entered numbers with decimal, the conversion didn't work.[code...]

View 12 RepliesSo the server I am running has a database of players equipment, I am trying to write a program to see if they are hacking by comparing the item requirement with the stats the player has, to do this I need to convert the varbinary(512) column from the SQL Database too a Hexadecimal string, then from that string remove certain parts of it.
Example:This is the hexadecimal code for an item:
0x440047000028000000000000896B4685
the part I need is "4400" numbers (Position 3,4,5,6 from start) I then need to flip these backwards so it reads "0044". I then will compare this itemIDX with a list of items I have set aside that people mainly use this hack for.
So the main things I need help with, are converting varbinary(512) to hexadecimal and then making my program bring a list of accountID's up who are using the hack, here is how the databases are set out:
Account:
Contains account data ONLY
Game:
Contains the Character and Equipment DB
i need to compare the equipmentDB, then return the CharacterID from the equipmentID, compare that ID with the CharacterID in CharacterDB, then extract the accountID then return the account name from the accountDB I don't know how the binary is split up from item too item, although I would imagine, it isn't, i would have thought it just goes onto the next item when the item ends.Although, all the items start with hex string "0x" so this may be the separator!
I'm writing a small program that will convert a negative number (e.g. -200) to a hexadecimal number (e.g. FF38). And back to a decimal number. FF38 back to -200. (I can only use two bytes when converting back and forth.)
Question: is there a function in VB that will help?

View 14 RepliesPossible Duplicate: How to convert numbers between hexadecimal and decimal in C#? In C, you can do something like int x = 255; printf("x is: %d and in HEX, x is: %x", x, x); How can I do that in C# or VB.net? print the variable's hex equivalent
View 7 RepliesThis program, it reads in a file, and displays it in hexadecimal, like using a hex editor. It then goes to compare the strings and whatnot, and display certain values. During the program, there is a time where I need to display a set of offsets as decimal because that is the way that it is shown regularly.
Taking the two specific offsets and displaying them in hex ends up giving me something like "3039" or "000A", which should respectively convert to 12345 or 00010. This "ID" that I am converting, can be 00000 to 65535, which in hex is 0000 to FFFF. The current method I was given only works if the value is less than 512 or something like that.

I have a DataGridView bound to a DataTable that has 1+16 columns defined as Integer.The default cell style is hexadecimal 2 digits (.Format="X2").When entering in cell editing I would like to provide to the user, the possibility to write the value in decimal or hexdacimal.Hexadecimal could be written like, for example, 0x00, 0X01, x02, XFF
Decimal like 0, 1, 2, 15For this reason in EditingControlShowing I add "0x" to the TextBox value

this is only for the decimal to binary part though. it keeps not wanting to work.
I write a program to convert Decimal numbers to Binary numbers. It is working well. But I want to control the bits. i.e - We can write 31 as a) 11111 or b) 011111. When I run my program it displays 11111. I want to take input bit from a text box and display it like 0011111 or 011111 or what ever bit I input. How can I do that ?
Private Sub DecToBin()
Dim i As Integer = txtDec.Text
Dim binary As String = Convert.ToString(i, 2)

I have a decimal I want to be able to display as a binary or a hex. I keep seeing code that says Convert.ToString(decimal, 2) to display as binary string, but in 3.5 that is invalid.
Is there no built in formating for binary in 3.5?

View 1 RepliesI was given a school project in which I have to make a program that converts numbers between binary,decimal,octal and hexadecimal systems. I have figured out how to make a function to convert binary number to decimal number [code]With this code,a user can enter a number that isn't binary,and program will calculate it. How can I make that program doesn't calculate those numbers or doesn't accept anything else than 0 or 1? This is needed for other cases like octal and hexadecimal system.

View 3 RepliesI'm doing a uni assignment regarding changing decimals to binary. However this assingment seems to be different to most of its kind from what I can see.Our assignment asks us to have a text box in which we'll enter the decimal, then we'll use a menuscript to and highlight the button 'dec-to-bin' which will then change the colour of 8 image boxes (located in a row above the text box) from black to red based on whether the binary is '1' (Red) or '0' (Black) for that bit.I've struggling to find a starting point as I need to ensure I link the text boxes to the outcome of the decimal and binary but not sure how.
