View 12 RepliesI'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?
This 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 4 radiobuttons hex dec oct bin all the buttons works perfectly except the Hex.When i calculate or press a number in decimal, and i check the Hex, the number will perfectly change into hexadecimal, but when i try to calculate within Hex, its a calculation in Decimal.So i repeat.. i can calculate in base 8 octal, base 2 decimal, and base 10 decimal, but i cant calculate in base 16... and i think it has something to do with the letter notation...

I have come across some Base64 conversion functions in .net(FromBase64.string etc). What i want is, for a sample, i have a base 64 encoded string as
"48YwojCi4yaiow==".
I need to convert this string to the corresponding Hexadecimal text(The sample stands for "Thisistest" in hex text) The below link is an online converter from base64 to hexadecimal text. If you give the same base64 encoded data in the link , click on convert, the one that is seen below "Hexadecimal text" is what I need.

I have an id called "AM01". I separated them by truncating the numbers out and increase it by 1 each time I want to add a new record. Therefore before I add the record, I would have to combine them back. I managed to truncate them and combine them back. However, the results turn out to be "AM2" instead of "AM02". So, is there a way where I could make the numbers as "02" instead of just "2"?

View 1 RepliesI'm having a bit of an issue getting the number formatting of VB .NET 3.5 to work just right for me. I have to convert numbers to scientific notation, with 2 digits for the exponent and 6 digits after the decimal. I've been able to get this for numbers that have enough digits, but for other numbers, it truncates the number to use as few digits as possible. For example, I would like 0 to be converted to 0.000000e00, or 123.4 to be 1.234000e02.
